Abstract

The present invention relates to a pallet for transporting coiled steel, and relates to the field of railway transportation technology. The pallet comprises a base and multiple rows of triangular seats supported on the base. Adjacent triangular seats form a coiled steel bearing space for inserting and positioning the coiled steel. The triangular seats comprise two left and right sets of triangular seat square tubes and abutment ramps arranged at the inclined side ends of the two sets of triangular seat square tubes. The abutment ramps have an inclination of 38-39 degrees. The beneficial effects are that the transport vehicle is more stable during the process of transporting coiled steel and the pallet can adapt to coils of a larger diameter range. The overall width of the base is reduced to allow for stacking of multiple pallets, reducing the weight to alleviate transportation pressure, and the support surface is widened to ensure support strength when the I-beam or channel steel is changed to a hollow square tube. This increases the transportation efficiency and economy when transporting empty pallets.

Background

Steel coil, also known as coil steel. Hot-pressing steel material cold press molding to form a coil shape. For convenience in storage and transportation, various processes (for example, processing into steel plates, steel strips, etc.) are facilitated.

There are two common methods of coil transportation, sea and rail transportation. The marine transport has the characteristics of low transport cost, large batch, wide coverage and the like for large-batch steel coil transport. Meanwhile, under the conditions of long-distance transportation, overseas transportation and the like, the sea transportation is a safer and more reliable mode. The railway transportation mode is one of the transportation modes which are relatively energy-saving and have little pollution to the environment, the railway can be connected with different regions of the country, the rapid transportation of large-scale steel coils is convenient, and the railway transportation mode has the defects of relatively long transportation time and inapplicability to relatively urgent transportation.

Thus, the prior art has attempted a number of methods to improve the stability of coil steel in railway wagons. In general, pallets are used to hold coil steel in open railroad cars. The tray comprises a tray base and a plurality of rows of triangular seats arranged on the tray base, a space for placing coil steel is formed between two adjacent rows of triangular seats, so that the coil steel is positioned, the conventional triangular seats are formed by left and right metal I-shaped steel or channel steel, the supporting surface is 45 degrees, the gravity center of the coil steel is upwards moved by 45 degrees, and then the railway open wagon is more easily influenced by the coil steel in the transportation process, so that the transportation is not stable enough.

Meanwhile, most of research and development at present is to consider the safety and stability of the coiled steel transportation. Often neglect the tray of bearing coil steel itself and also have the defect in the transportation, like when transporting the tray (not carrying the coil steel), often a plurality of trays pile up, because of tray monomer weight is big, the layer number of pile up is few, and the cost of transportation is high, and then influences conveying efficiency and economic nature.

Detailed Description

The invention will be better explained by the following detailed description of the embodiments with reference to the drawings.

Example 1

Referring to fig. 1 and 4, a pallet for transporting coiled steel comprises a base and two rows of triangular bases 6 supported on the base, wherein the two rows of triangular bases 6 are arranged at intervals to form a coiled steel bearing space, and the pallet is a single-groove pallet in the embodiment.

The triangular base 6 includes two groups of triangular base square tubes 62 which are connected and form an included angle, each group of triangular base square tubes 62 includes two triangular base square tubes 62 which are arranged at intervals from front to back, all triangular base square tubes 62 in a group of triangular base square tubes 62 facing the coil steel bearing space are parallel to each other and are fixed with an abutting inclined plate 63 thereon, in the embodiment, due to the single-groove tray, only one side of each triangular base forms a supporting surface for coil steel by the abutting inclined plate 63. In describing the triangular base 6, the front-rear direction is taken along the axial direction when the coil is placed in the coil-carrying space, and the left-right direction is taken along the direction perpendicular to the axial direction.

As above, the two sides of the triangular base are provided with a plurality of square tubes instead of the original I-steel or channel steel, the thickness of a single square tube can be reduced under the condition of obtaining the same supporting strength, the mass of the square tube relative to the I-steel or channel steel can be reduced, and the width of the square tubes after being arranged side by side can be obviously larger than the width of the original I-steel or channel steel so as to provide a wider supporting surface. Therefore, comprehensively considering the scheme of the single-side multiple square tubes, the invention can simultaneously reduce the height of the base single body to stack a plurality of trays, lighten the mass to lighten the transportation pressure, widen the supporting surface to ensure the supporting strength under the condition that I-steel or channel steel is changed into a hollow square tube, and further improve the transportation efficiency and economy when transporting empty trays.

Further, in the present embodiment, the angle of the abutment inclined plate 63 with respect to the horizontal plane is 38 to 39 degrees. When the coil steel is placed in the coil steel bearing space, the center of gravity of the coil steel is lower, so that the center of gravity of the railway open wagon during transportation of the coil steel is reduced, and the stability and the safety are improved. Meanwhile, the tray can be adapted to coil steel with a larger diameter range.

Further, the abutment inclined plate 63 includes a metal plate layer and a deformed anti-slip adhesive layer 6411 covering the metal plate layer to reduce abrasion of the coil steel while having sufficient supporting strength. Specifically, the metal plate layer abutting the sloping plate 63 and the deformed anti-skid glue layer 6411 are fixed by bolts, and the metal plate layer is welded on the triangular base square tube 62.

In this embodiment, the base includes a rectangular bottom frame a, and a cross beam and a longitudinal beam welded inside the rectangular bottom frame a.

The rectangular bottom frame A comprises four square steels 1 which are arranged in a rectangular mode, adjacent square steels 1 are perpendicular to each other, and the adjacent square steels 1 can be directly connected or indirectly connected through other structures.

At the four corners of the rectangular bottom frame a and at the open ends 12 of the square steel 1 there is mounted one spreader 5 each, i.e. one spreader 5 is arranged at each corner of the rectangular bottom frame a. From the view of fig. 1, three spreaders 5 are visible, the other spreader 5 being blocked by the coil steel.

In this embodiment (see fig. 1-4), four spreaders 5 are mounted on a pair of opposed square steels 1 of a rectangular base frame a, both ends of the square steels 1 being open ends 12, one spreader 5 being mounted at each end of each square steel 1. As can be seen from the figure, the lifting devices 5 are arranged on two square steels 1 corresponding to two axial ends of the coiled steel, and the direction of the lifting devices 5 extending out from the open ends 12 of the square steels 1 is two horizontal directions perpendicular to the axial direction of the coiled steel bearing space.

A part of the spreader 5 is inserted in the open end 12 of the square steel 1, the part located in the square steel 1 being referred to as the rear part, and the part exposed outside the square steel 1 being referred to as the front part.

The hook portion 51 includes a first plate 511, and the first plate 511 protrudes from the open end 12 of the square steel 1 and is provided with a first hanging hole 512 exposed to the square steel 1, in other words, the first hanging hole 512 is provided at the front of the first plate 511. The first hanging hole 512 penetrates the first plate 511 in the thickness direction of the first plate 511 and penetrates the bottom wall of the first plate 511, thereby forming a hook shape of the protruding end of the hook portion 51. In short, the first suspension hole 512 of the hook portion 51 for engagement with the suspension tool is open, and is adapted for the suspension tool to be a wire rope loop.

Further, in this embodiment, the first plate 511 is generally rectangular and includes two parallel, relatively large-area side walls, a top wall, a bottom wall, a rear wall, a front wall, and a curved wall. The top wall and the bottom wall are parallel and perpendicular to the side wall, the back wall and the front wall are parallel and perpendicular to the side wall, and the curved wall is connected between the front wall and the bottom wall to outline the hook-shaped front end.

The end of the first plate 511 protruding from the open end 12 of the square steel 1 is formed into a hook shape, and the bottom wall of the hook shape is retracted upward with respect to the bottom wall of the first plate 511, i.e., a short hook is formed to be more easily engaged with the suspension means.

The ring portion 52 includes a second plate 521, the second plate 521 protruding from the open end 12 of the square steel 1 and provided with a second hanging hole 522 exposed to the square steel 1, the second hanging hole 522 penetrating through the second plate 521 only in the thickness direction of the second plate 521, thereby forming a loop shape of the protruding end of the ring portion 52. Briefly, the second suspension aperture 522 of the suspension ring portion 52 for engagement with a suspension tool is closed. The ring is not limited to a circular ring, but only means that the suspension hole for engagement with the suspension tool is closed, and that the suspension tool is suitably a steel hook.

Further, in this embodiment, the second plate 521 is rectangular and includes two parallel, larger-area side walls, a top wall, a bottom wall, a rear wall, and a front wall. The top and bottom walls are parallel and perpendicular to the side walls, and the rear and front walls are parallel and perpendicular to the side walls.

The first plate 511 and the second plate 521 are parallel, i.e. the side wall of the first plate 511 is parallel to the side wall of the second plate 521. Meanwhile, the top wall of the first plate 511 and the top wall of the second plate 521 are coplanar and parallel to the top wall of the square steel 1, the bottom wall of the first plate 511 and the bottom wall of the second plate 521 are coplanar and parallel to the bottom wall of the square steel 1, and can be stably supported in the square steel 1 after being inserted into the open end 12 of the square steel 1. The first suspension hole 512 includes a semicircular hole and a rectangular hole smoothly connected to the semicircular hole, the rectangular hole penetrates through the bottom wall of the first plate 511, the second suspension hole 522 is a circular hole, and the axes of the semicircular hole and the circular hole are coincident.

Also, the arrangement direction of the first and second plates 511 and 521 is a lateral direction, i.e., the first and second plates 511 and 521 are arranged in the width or length direction of the rectangular bottom frame a, i.e., in the width or length direction of the railway flatcar placed later, instead of being stacked one on top of the other.

In the present embodiment, since the three-groove pallet is used, only one side of the two triangular bases positioned at both ends forms a supporting surface for coil steel by the abutment sloping plate 63, and both sides of the two triangular bases positioned in the middle form a supporting surface for coil steel by the abutment sloping plate 63.

The lifting appliance in the first embodiment is omitted, and a traditional hook is arranged on the side face of the rectangular bottom frame A.

Example III

Referring to fig. 6-14, the difference between the present embodiment and the first embodiment is mainly that the triangle base structure is different, the suspension structure of the rectangular bottom frame a is different, and a special corner piece and a blocking component are added. The specific description is as follows:

In this embodiment, five rows of triangular bases 6 are provided, and two adjacent rows of triangular bases 6 are arranged at intervals to form a coil steel bearing space, and in this embodiment, a four-groove tray is provided, namely, four rows of coil steels can be placed.

Wherein, a horizontal reinforcing beam is added between two triangular seat square tubes 62 on the same side of the triangular seat 6.

In particular, in this embodiment, four pairs of blocking assemblies 2 are provided on both side walls of the rectangular bottom frame a along the width direction of the railway open wagon, that is, on the side walls of the square steel 1 on the left and right sides, so as to be particularly suitable for the case where the transport vehicle is the railway open wagon. The catch assembly 2 can abut the front or rear side of the reinforcement seat 31 on the side wall 3 of the railway gondola when the pallet is dropped onto the floor of the railway gondola.

Specifically, three reinforcement seats 31 are arranged on one side wall 3 of the railway open wagon from front to back, and among four clamping and blocking assemblies 2 on the same side of the rectangular base, two middle clamping and blocking assemblies 2 are positioned on two sides of the reinforcement seat 31 in the middle of the side wall 3, a first clamping and blocking assembly 2 positioned in front is positioned on the rear side of the reinforcement seat 31 corresponding to the side wall 3, and a first clamping and blocking assembly 2 positioned in rear is positioned on the front side of the corresponding reinforcement seat 31. Of course, it is not limited to the four catch assemblies 2 on one side all abut against the three reinforcing seats 31, and as long as one catch assembly 2 abuts against the front side of one reinforcing seat 31, the other catch assembly 2 abuts against the rear side of the same or the other reinforcing seat 31, so that the longitudinal limit of the whole tray can be realized.

The blocking component 2 comprises a main blocking component 21, wherein the main blocking component 21 is made of steel and is fixedly connected with the square steel 1 in the rectangular bottom frame A. The side of the main catch 21 facing away from the square steel 1 is provided with a groove. The catch assembly 2 further comprises a catch 22 which is connected to the main catch 21 in a vertically rotatable manner by means of a support shaft 23 and is located in the recess, the catch 22 being a steel part. The tongue 22, in the state shown in the figures, protrudes from the recess, i.e. laterally outwards with respect to the main catch 21.

The upper side of the latch 22 is provided with a first elastic piece 24, the lower side is provided with a second elastic piece 25, one ends of the first elastic piece 24 and the second elastic piece 25, which are close to the rectangular bottom frame A, are connected with the main catch 21, and in the embodiment, the first elastic piece 24 and the second elastic piece 25 are fixed through a plurality of bolts 54 penetrating through the main catch 21.

The first elastic piece 24 and the second elastic piece 25 press against the upper surface and the lower surface (the rear surfaces of the upper inclined surface 221 and the lower inclined surface 222 described later) of the latch 22 in a natural state, so that the latch 22 is in a natural position, that is, the force provided by the first elastic piece 24 and the second elastic piece 25 to the latch 22 is symmetrical.

The first elastic piece 24 includes a first long elastic piece 241 and a first short elastic piece 242, the first long elastic piece 241 is longer than the first short elastic piece 242, the first long elastic piece 241 is abutted to the latch 22, the first short elastic piece 242 is overlapped with the first long elastic piece 241, and the first long elastic piece 241 covers more area of the latch 22 towards the extending direction of the latch 22 relative to the first short elastic piece 242. The second elastic piece 25 includes a second long elastic piece 251 and a second short elastic piece 252, the second long elastic piece 251 is longer than the second short elastic piece 252, the second long elastic piece 251 is abutted with the latch 22, the second short elastic piece 252 is overlapped with the second long elastic piece 251, and the second long elastic piece 251 covers more area of the latch 22 towards the extending direction of the latch 22 relative to the second short elastic piece 252.

In this embodiment, the elastic sheet is used to provide a restoring force, so that the checking and replacement are facilitated, and of course, other embodiments of the present invention may be modified by setting a torsion spring on the supporting shaft 23. When the long elastic sheet returns to a state of tending to be flat, the given force becomes very small by utilizing the long elastic sheet, and the short elastic sheet is used for assisting the long elastic sheet to return. In addition, the long elastic sheet can be prevented from losing elasticity due to local fatigue. One or more shims 26 may be provided between the long and short spring plates to adjust the spacing therebetween, for example, to reduce the number of shims 26 used if the return force is not good, and to increase the number of shims 26 if the latch 22 is bent upward or downward with excessive force.

The tongue 22 rotates up and down with respect to the main catch 21 between a first, upwardly inclined, yielding position, a horizontal, natural position, and a second, downwardly inclined yielding position. The end of the tongue 22 extending out of the groove of the main catch 21 is formed by an upper inclined surface 221 and a lower inclined surface 222 which taper toward the extending direction, the upper inclined surface 221 and the lower inclined surface 222 are connected by an arc end surface, and the inclination of the upper inclined surface 221 and the lower inclined surface 222 are the same. The front side 223 and the rear side 224 of the end of the tongue 22 protruding from the recess of the main catch 21 are vertical planes.

The catch 22 protrudes laterally outwards in relation to the main catch 21 in the natural position, i.e. in a direction away from the rectangular bottom frame a.

In the process that the tray falls into the railway open wagon from top to bottom, the clamping tongue 22 is firstly pushed by the side wall 3 cross beam of the railway open wagon to rotate upwards from a natural position to a first abdication position, in the process, the lower inclined surface 222 of the clamping tongue 22 is pushed by the side wall 3 cross beam, and is pushed to be vertical to the lower inclined surface 222 and flush with the end surface of the main clamping block 21, and the upper inclined surface 221 is horizontally oriented. Therefore, the clamping tongue 22 rotates into the groove of the main clamping block 21 and does not transversely extend out of the groove, so that the clamping block assembly 2 can pass through the beam of the side wall 3, meanwhile, the first elastic sheet 24 bends upwards along with the clamping tongue 22 to store force (at the moment, both the first long elastic sheet 241 and the first short elastic sheet 242 bend upwards), the second elastic sheet 25 does not move, and when the clamping block assembly 2 passes through the beam of the side wall 3, the clamping tongue 22 is reset from the first yielding position to the natural position under the action of the reset force of the first elastic sheet 24.

In the process of moving the tray out of the railway open wagon from bottom to top, the clamping tongue 22 is firstly pushed by the side wall 3 cross beam to rotate downwards from a natural position to a second abdication position, the upper inclined surface 221 of the clamping tongue 22 is pushed by the side wall 3 cross beam and is pushed to be vertical to the upper inclined surface 221 and flush with the end surface of the main clamping block 21, and the lower inclined surface 222 is horizontally oriented. Therefore, the clamping tongue 22 rotates into the groove of the main clamping block 21 and does not transversely extend out of the groove any more, so that the clamping block assembly 2 can pass through the beam of the side wall 3, meanwhile, the second elastic sheet 25 bends downwards along with the clamping tongue 22 to store force (at the moment, both the second long elastic sheet 251 and the second short elastic sheet 252 bend downwards), the first elastic sheet 24 does not move, and when the clamping block assembly 2 passes through the beam of the side wall 3, the clamping tongue 22 is reset from the second yielding position to the natural position under the action of the reset force of the second elastic sheet 25. In summary, the effective width of the tray is increased by the outward protruding tongue 22 in the natural state, the depth of engagement with the reinforcement seat 31 is increased, and the stability is improved. Meanwhile, the side wall 3 cross beam is avoided through rotation of the clamping tongue 22, and accordingly smooth loading of the tray is guaranteed. Specifically, in the normal loading condition, the portion of the main catch 21 protruding from the tray is used to abut against and abut against the reinforcing seat 31 to play a role of a main catch, and in the condition that the tray is jumped, the main catch 21 jumps out of the reinforcing seat 31, and the front side 223 or the rear side 224 of the protruding portion of the catch 22 abuts against the reinforcing seat 31 immediately due to the protruding of the catch 22 relative to the main catch 21, so as to continuously contribute to the longitudinal limit of the tray, which can be understood as the catch 22 being an auxiliary catch or a remedial catch.

In this embodiment, the vehicle body inner width is 2900mm, and the distance between the two side wall 3 cross members is 2800mm. Based on this:

the width of the pallet at the outer ends of the two side main catches 21 is 2780-2800mm, thus ensuring that the rigidly fixed main catches 21 can pass over the cross beam of the side wall 3.

When the clamping tongue 22 is positioned at the natural position, the width of the widest part of the tray (namely, the transverse distance between the arc end faces of the clamping tongue 22 in the two symmetrical clamping and blocking assemblies 2) is 2840-2890mm, the length of the clamping tongue 22 extending out of the groove is 20-50mm, and thus, the matching depth of the clamping tongue 22 with the reinforcing seat 31 is increased by 20-50 mm.

When the latch 22 is located at the first yielding position and the second yielding position, the upper inclined plane 221/the lower inclined plane 222 of the latch 22 are flush with the end surface of the main catch 21 in the present embodiment, so that the width of the widest part of the tray is the width of the tray at the outer ends of the main catches 21 at two sides, that is, 2780-2800mm. Of course, the present invention is not limited to this, and when the clamping tongue 22 is located at the first yielding position and the second yielding position, the clamping tongue may not completely rotate to enter the groove, but the width of the widest part of the tray is ensured to be less than or equal to 2800mm at this time, so that the tray can smoothly pass through the side wall 3 beam.

The main catch 21 includes two side supports 211, an upper plate 212 and a lower plate 213, the two side supports 211 being spaced apart to form a recess for receiving the catch 22, the catch 22 being rotatably supported on the two side supports 211. The upper plate 212 is extended from both arms to be coupled to the top ends of both side supporters 211, thereby forming grooves, the lower plate 213 is coupled to the lower rear ends of both side supporters 211, the upper plate 212 covers the upper surface of the square steel 1 of the rectangular bottom frame a and is fixed to the square steel 1 of the rectangular bottom frame a, preferably by welding, and the lower plate 213 is fixed to the side wall of the square steel 1 of the rectangular bottom frame a, preferably by welding.

In this embodiment, the side supporting piece 211 is a U-shaped seat with an upward opening, which can improve the rigidity of the whole structure and reduce welding. The U-shaped seat is provided with a supporting hole connected with the supporting shaft 23. The front side 223 and the rear side 224 of the U-shaped seat are both vertical planes, and the front side 223 and the rear side 224 of the side support 211 are both vertical planes so as to be convenient for abutting against the corresponding reinforcing seat 31.

In the embodiment, the side wall of the rectangular bottom frame A is also provided with a stop bar 13 connected with the blocking component 2, the stop bar 13 is retracted relative to the main blocking component 21, and when the tray falls on the floor of the railway open wagon, the stop bar 13 can be abutted with the inclined surface of the reinforcing seat 31 facing the center line of the railway open wagon. The stop strip 13 can promote the limitation of the lateral movement of the tray.

Referring to fig. 11 to 13, the tray base a includes a rectangular bottom frame including four square steels 1 arranged in a rectangular shape, adjacent square steels 1 are perpendicular to each other, and the adjacent square steels 1 may be directly connected or indirectly connected through other structures. In this embodiment, the square steel 1 is connected at four corners of the rectangular bottom frame through hollow corner pieces 14, the bottom wall of the corner piece 14 is provided with long holes 141 which can be spliced with mushroom heads 4 of container locking devices on the railway container flatcar, so that the pallet of this embodiment can also be used for the railway transportation container flatcar (four-slot pallets are connected by 4 corner pieces, and three-slot pallets and single-slot pallets are only provided with 2 corner pieces 14 at one end of the seat frame, because the total length of the three-slot pallets and the single-slot pallets does not reach the length of the container, when the three-slot pallets and the single-slot pallets are used on the flatcar, one side of the corner piece 14 is embedded into the mushroom heads 4, and the other side of the corner piece 14 is bound with a car body by steel wires).
