Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a cargo handling device in a cargo hold, and particularly to cargo handling equipment in a cargo hold for transporting cargo carried into a cargo hold to a desired location and stacking or transshipping it. Regarding equipment.

[Prior Art] Cargo ships that transport frozen cargo and the like are generally equipped with cargo handling equipment such as an overhead crane in their holds.

[Problems to be Solved by the Invention] However, since there are usually a number of pillars, etc., arranged in a row inside a hold, it is difficult to handle cargo within the entire area of the hold with a single overhead crane. there were.

For this reason, conventionally, by installing a large number of relatively small overhead cranes within the hold within a range that does not interfere with the supports etc.
Although this system was designed to handle cargo within the entire range of the cargo hold, it had the disadvantage that the volume occupied by the cargo handling equipment became large, which limited the amount of cargo that could be loaded.

[Object of the Invention] The present invention has been made in order to eliminate the drawbacks of the above-mentioned prior art, and its purpose is to be able to handle the entire range of cargo in a cargo hold with a single device, and to reduce the volume occupied by the cargo handling device. An object of the present invention is to provide a cargo handling device in a hold that can greatly increase the amount of cargo to be loaded.

[Summary of the Invention] In order to achieve the above object, the present invention provides a girder in the central part of the ceiling in the hold so that it can span in the width direction of the ship and move freely in the ship's direction, and a shuttle beam is connected to the girder via an intermediate beam. The shuttle beam is provided so as to be movable in both directions of the ship's width, and the hoist is movable along the shuttle beam.

In FIG. 1, 1 is the interior of a cargo ship, the ceiling of which is covered with a deck 2, and this deck 2 is provided with a hatch 4 for carrying cargo 3 in and out.

A girder 5, which constitutes a part of the cargo handling device in the hold according to the present invention, is hung in the center of the ceiling of the hold 1 in the width direction of the ship.
It is installed so that it can run freely in the direction of the ship's captain. In particular, Garda 5
is set to a length that does not interfere with the support column 6, etc. Pillar 6
are erected from the bottom 7 of the ship to support the deck 2, and are arranged at appropriate intervals in the ship width direction and the ship length direction. The girder 5 is configured to run between struts 6, 6 disposed on both sides of the center in the width direction of the ship.

In order to guide the running of the girder 5, FIG.

As shown in FIG. 3, a set of guide rails 8.8 are installed parallel to each other along the longitudinal direction of the pillars 6.6 on opposite inner sides thereof, and the guide rails 8.8 are attached to both ends of the girder 5.
Wheels 9, which move over the guide rails 8, are mounted so as to sandwich the guide rails 8, 8 from above and below. Further, as traveling means for the girder 5, traveling chains 10 and 10 are fixedly stretched along the longitudinal direction on the opposing inner sides of the guide rails 8.8, and the traveling chains 10 and
A traveling drive 13 is provided which has drive sprockets 11.11 meshed at 10° at both ends of the rotating shaft 12. As shown in FIG. 4, guide sprockets 14 and 14 for winding the chain 10 around the drive sprocket 11 are provided on both sides of each drive sprocket 11, respectively.

At the bottom of the girder 5 there is an intermediate beam 1 along its longitudinal direction.
5, a shuttle beam 16 is provided so as to be movable laterally in both directions in the width direction of the ship, and a hoist 17 is provided on the shuttle beam 16 so as to be movable transversely along the longitudinal direction of the shuttle beam 16. The intermediate beam 15 and shuttle beam 16 are connected to the girder 5
Seven flange portions 18 and 19 are formed along the longitudinal direction at the top and bottom of the shuttle beam 16. The intermediate beam 15 is formed to have an inverted U-shape in cross section,
Guide rollers 20 that support the upper flange portion 18 of the shuttle beam 16 in a traverse manner are installed at appropriate intervals along the longitudinal direction on the opposing inner side, and traverse wheels are installed on the outer side of the shuttle beam 16 along the longitudinal direction. 21... are installed at appropriate intervals. The lower part of the girder 5 is formed into an inverted U-shape in cross section, and the opposite inner side has a traversing rail 2 for guiding the traversing heavy wheels 21 of the intermediate beam 15.
2.22 are arranged along the longitudinal direction.

The intermediate beam 15 can telescopically move in and out of the girder 5, and the shuttle beam 16 can move in and out of the intermediate beam 15 telescopically in both directions, and are prevented from being handled when projected through a stopper (not shown). In particular, the extension lengths of the intermediate beam 15 and the shuttle beam 16 are set so that the tip of the shuttle beam 16 can reach the side wall 23 of the hold 1 in its maximum extension state.

The hoisting machine 17 has a base 25 that is suspended from the lower flange 19 of the shuttle arm 16 via wheels 24 for traversing. 2
6 is installed. The tip of the hoisting loaf 127 fed out from the hoisting drum of the hoisting machine body 26 is fixed to the base 25, and a hanging beam 28 is suspended from the hoisting loaf 27 via a sheave 29 provided at its upper end. The cargo 3 is suspended from the suspension beam 28.

And the intermediate beam 15. As a means for moving the shuttle beam 16 and the hoist 17 laterally, the following driving method using lobes or chains is adopted. That is, as shown in FIG. 5, the girder 5 is provided with a driving sprocket 30 for traversal at the right end and a driven sprocket 31 at the left end, and one end 32a is fixed to the left end of the intermediate beam 15, and from this the driving sprocket 30 is installed. and driven sprocket 3
The other end 32b of the intermediate beam traverse chain 32, which is wound around the intermediate beam 15 in turn, is fixed to the right end of the intermediate beam 15. Also, sprockets 33.3 are provided at both ends of the intermediate beam 15.
4 is arranged, one end 35a is fixed to the left end of the girder 5, and the other end of the first chain 35 for shuttle beam traversal, which is wound around the right end sprocket 33 of the intermediate beam 15, is fixed to the left end of the shuttle beam 16. At the same time, one end 36a is fixed to the right end of the girder 5, and the other end 36b of the second shuttle beam traverse chain 36, which is wound around the left end sprocket 34 of the intermediate beam 15, is fixed to the right end of the shuttle beam 16. ing. Furthermore, sprockets 37 and 38 are arranged at both ends of the shuttle beam 16, and one end 39a is fixed to the left end of the intermediate beam 15, and from this the sprocket 37, 38 for hoisting and surfing the shore is wound around the right end sprocket 37 of the shuttle beam 16. The other end 39b of the 1 chain 39 is fixed to the right end of the hoist 17, and one end 40a is fixed to the right end of the intermediate beam 15, from which the shuttle beam 1
The other end 40 b of the second chain 40 for hoisting and rock traversing, which is wound around the left end sprocket 38 of No. 6, is fixed to the left end of the hoist 17 .

A traverse drive device 41 for driving the traverse drive sprocket 30 is connected to the traverse drive sprocket 30.

Next, we will discuss the effect. For example, when the intermediate beam 15 is caused to traverse to the right by rotation of the drive sprocket 30 by the traverse drive device 41, the first chain 35 for shuttle beam traverse is pulled by the right end sprocket 33 of the intermediate beam 15, and thereby the shuttle beam 16 moves to the right.

At this time, the first chain 39 for traversing the hoisting machine is pulled by the right end subrockets 1 to 37 of the shuttle beam 16 that traverses to the right, so the hoisting machine 17 also traverses to the right. In this case, the shuttle beam 16 will traverse at twice the traverse speed of the intermediate beam 15, and the hoist 1117 will traverse at three times the traverse speed of the intermediate beam 15, so the hoist 17 will be moved in the transverse direction of the ship. can be quickly moved to the desired location.

Next, when the girder 5 is to travel, the shuttle beam 16 and the intermediate beam 15 are first stored under the girder 5, and the travel drive device 13 is started. As a result, the traveling driving tin rocket 11°11 is connected to the traveling chain 10.
．． By rolling on the girder 10, the girder 5 travels in the longitudinal direction without interfering with the strut 6.

By combining these operations, the hoisting machine 17 can be spread over the entire area of the hold 1 without interfering with the pillars 6, etc., and cargo handling of the entire area inside the hold can be achieved with one cargo handling device. .

In the embodiment, one traverse drive device 41 drives not only the traverse of the intermediate beam 15 and the shuttle beam 16 but also the traverse of the hoist 17, but the hoist 1
7 may be made to traverse independently by providing a separate traversing means for the shuttle beam 16. Further, in the embodiment, the traverse drive means is simplified by adopting a lobe or chain drive system, but a traverse drive fJ+ means such as a rack and pinion type may be provided for each beam. Furthermore, although there is one intermediate beam 15 in the embodiment, two or more intermediate beams 15 may be combined depending on the depth in the width direction of the ship.

[Effects of the Invention] In summary, the present invention exhibits the following excellent effects.

(1) The shuttle beam is provided on the girder via an intermediate beam so that it can move in and out in the transverse direction of the ship, allowing the hoist to move freely in parallel in the transverse direction of the ship.
Since the shuttle beam and intermediate beam can be stored in a compact state on the girder and run in the direction of the ship's ship, the hoisting machine can be moved throughout the entire area of the hold without interfering with the pillars set up inside the hold. The cargo handling equipment can handle the entire range of cargo within the hold.

(2) As a result, the number of cargo handling devices in the hold can be reduced all at once, so the volume occupied by the cargo handling HU can be reduced, thereby achieving a significant increase in the amount of cargo loaded.
