Abstract
Description
본 발명은 도로 컷팅장치에 관한 것으로, 더욱 상세하게는 도로를 컷팅하는 컷팅체의 승하강 동작은 물론 좌우측 이동 동작이 용이하여 도로 컷팅작업에 따른 편의성과 작업성을 크게 향상시킬 수 있는 도로 컷팅장치에 관한 것이다.The present invention relates to a road cutting device, and more specifically, to a road cutting device that can greatly improve convenience and workability in road cutting work by facilitating the raising/lowering motion as well as the left/right movement motion of a cutting body for cutting a road.
일반적으로 지중의 수도나 전기 통신선로 또는 도로의 신설이나 개보수공사시에는 지면 위에 기 시공되어 있는 아스팔트 도로나 콘크리트 포장을 절단할 필요가 있으며, 이러한 아스팔트 도로나 콘크리트 포장을 절단하기 위한 수단으로 도로 컷팅장치가 사용되고 있다.Generally, when constructing or repairing underground water lines, electric communication lines, or roads, it is necessary to cut the asphalt roads or concrete pavements that are already constructed on the ground, and a road cutting device is used as a means to cut such asphalt roads or concrete pavements.
종래 도로 컷팅장치는, 작업자가 손으로 파지하는 손잡이를 갖는 본체와, 상기 본체의 전방측에 구비되는 컷팅부와 상기 컷팅부를 회전시키는 모터동력부와 상기 손잡이를 잡고 작업자가 이동하는 것에 의해 상기 본체가 이동되도록 하는 바퀴로 이루어져 있으며, 통상 작업자가 손잡이를 잡은 상태로 본체를 밀어주면서 모터동력부의 동력에 의해 회전되는 컷팅부에 의해 도로면이 컷팅되도록 하고 있다.A conventional road cutting device is composed of a main body having a handle that a worker holds with his or her hand, a cutting section provided on the front side of the main body, a motor power section that rotates the cutting section, and wheels that allow the main body to be moved by the worker holding the handle and moving it. Normally, a road surface is cut by the cutting section that is rotated by the power of the motor power section while the worker holds the handle and pushes the main body.
이러한 도로 컷팅장치는, 하나의 컷팅날에 의해 도로를 컷팅함에 따라 도로의 폭에 따라 도로면의 좌측과 우측을 번갈아가면서 컷팅해야 하기 때문에, 도로 컷팅작업이 지연됨은 물론, 컷팅라인이 일정하지 못하고 좌우 동일한 간격으로 컷팅하기 어려운 문제점이 있다.Since these road cutting devices must cut the road alternately on the left and right sides of the road surface depending on the width of the road as the road is cut by a single cutting blade, not only is the road cutting work delayed, but the cutting line is not constant and it is difficult to cut at the same intervals on the left and right.
또한, 컷팅체를 이동할 때 승강시킨 후, 도로를 컷팅할 때 컷팅체를 하강시켜야 하는 바, 컷팅체의 승강 및 하강 동작이 모두 수작업으로 이루어질 뿐만 아니라, 작업자가 무거운 컷팅장치를 손으로 직접 밀어주면서 도로면을 컷팅함에 따라, 도로 컷팅작업에 따른 작업자의 피로감이 가중되는 문제점이 있으며, 특히 더운 여름철의 뜨거운 도로면 열기를 작업자가 그대로 받으면서 도로를 컷팅함에 따라 작업자의 피로감이 빠르게 증대되는 문제점이 있다.In addition, since the cutting body must be raised and lowered when moving and cutting the road, both the raising and lowering operations of the cutting body are performed manually, and since the worker cuts the road surface while directly pushing the heavy cutting device by hand, there is a problem that the worker's fatigue increases due to the road cutting work, and in particular, since the worker is directly exposed to the hot road surface heat during the hot summer, there is a problem that the worker's fatigue increases quickly as the worker cuts the road.
즉, 종래 기술로, 등록특허 10-0638858호인 콘크리트 포장 도로용 커팅기가 안출된 바 있으며, 이는 몸체 상부에는 사용자가 파지하여 이동시킬 수 있는 손잡이가 설치되며 하부에는 이동 시 회전하여 지면을 따라 구르는 이동바퀴가 장착된 케이싱부와, 상기 케이싱부에 설치되며, 회전 동력을 발생시키는 엔진부와, 상기 케이싱부에 회동 가능하고, 분리하여 교체할 수 있도록 장착되어 상기 엔진부의 회전동력에 의해 회전하여 콘크리트 도로를 커팅하는 절삭부와, 상기 엔진부에서 발생되는 회전 동력을 절삭부로 전달시켜 절삭부를 회전시키는 동력전달부와, 상기 케이싱부의 앞측에 장착되어 이 케이싱부의 전방을 들어올려 상기 절삭부의 높이를 조정할 수 있는 높이조절장치로 구성된 것에 있어서, 상기 절삭부는 원판의 외주면에 두께를 가지는 줄눈홈절삭날이 구비되는 제1절삭날부재와, 상기 제1절삭날부재의 직경보다 작은 직경을 가지는 원판으로 형성되어 그 외주면에 하부에서 상부로 경사진 제1경사절삭면이 형성된 제1우각부절삭날이 구비되어 상기 제1절삭날부재의 일측면에 장착 고정되는 제2절삭날부재와, 상기 제2절삭날부재와 동일한 직경을 가지는 원판으로 형성되어 그 외주면에 상기 제1우각부절삭날과 대칭으로 하부에서 상부로 경사진 제2경사절삭면이 형성된 제2우각부절삭날이 구비되어 상기 제1절삭날부재의 타측면에 장착 고정되는 제3절삭날부재로 구비되고, 작업자가 엔진을 작동시켜 절삭부를 회전시킨 상태에서 콘크리트 도로의 노면을 따라 이동하면 제1절삭날부재에 의해 줄눈홈이 절삭되고, 제2, 3절삭날부재의 제1, 2우각부절삭날이 제1절삭날부재로 절삭된 줄눈홈의 모서리를 테이퍼지도록 절삭하여 우각부로 이루어져 있다.That is, as a conventional technology, a cutting machine for a concrete pavement road, registered patent number 10-0638858, has been devised, which comprises a casing part having a handle installed on the upper part of the body so that the user can hold and move it, and a moving wheel installed on the lower part that rotates and rolls along the ground when moved, an engine part installed on the casing part and generating rotational power, a cutting part that is rotatably mounted on the casing part and can be separated and replaced, and rotates by the rotational power of the engine part to cut the concrete road, a power transmission part that transmits the rotational power generated from the engine part to the cutting part to rotate the cutting part, and a height adjustment device installed on the front side of the casing part to raise the front of the casing part to adjust the height of the cutting part, wherein the cutting part comprises a first cutting blade member having a grooved cutting blade having a thickness on the outer surface of the disc, and a first inclined cutting surface formed on the outer surface thereof by a disc having a diameter smaller than the diameter of the first cutting blade member and inclined from the bottom to the top. A second cutting blade member having a first right-angled cutting edge and being mounted and fixed to one side of the first cutting blade member, and a third cutting blade member having a second right-angled cutting edge formed as a disk having the same diameter as the second cutting blade member and having a second inclined cutting surface formed on an outer surface thereof that is symmetrical to the first right-angled cutting edge from bottom to top, and being mounted and fixed to the other side of the first cutting blade member, is provided, and when a worker operates the engine to rotate the cutting member and moves along the surface of a concrete road, a groove is cut by the first cutting blade member, and the first and second right-angled cutting edges of the second and third cutting blade members tape the edges of the groove cut by the first cutting blade member to form a right-angled portion.
이러한 종래 기술은, 줄눈홈의 모서리부를 절삭하여 우각부를 형성하는 작업을 한 번의 컷팅작업으로 할 수 있어 도로의 줄눈 시공 시 작업공수와 작업시간을 줄일 수 있도록 하고 있다.This conventional technology enables the work of cutting the corners of the joint groove and forming the right-angled portion to be done in a single cutting operation, thereby reducing the work manpower and work time when constructing joints on roads.
그러나, 종래 기술 역시 케이싱부에 구비되는 핸들을 수동으로 돌려주는 동작에 의해 컷팅체가 승강 및 하강되도록 이루어짐에 따라, 작업자의 피로감이 가중되어 쉽게 피로감을 느끼게 되는 문제점과 하나의 컷팅날에 의해 도로면이 컷팅되기 때문에, 도로면에 좌측과 우측에 컷팅라인을 형성할 때, 도로면의 좌측과 우측을 번갈아 컷팅해야 함에 따른 문제점 역시 해결하지 못하고 있는 실정이다.However, since the conventional technology raises and lowers the cutting body by manually turning the handle provided in the casing, it also has the problem that the worker's fatigue increases and he or she easily feels tired, and since the road surface is cut by one cutting blade, when forming cutting lines on the left and right sides of the road surface, the left and right sides of the road surface must be cut alternately, which has not been solved.
다른 예로, 등록특허 10-2133652호인 도로 컷팅기가 안출된 바 있으며, 이는 전륜과 후륜이 설치되는 본체부, 상기 본체부 전방측에 구비되는 탱크부, 상기 본체부 후방측에 구비되는 엔진부 및 상기 엔진부로부터 동력을 전달받아 회전되고 상기 본체부 후측 좌우에 구비되는 제1컷팅부 및 제2컷팅부를 포함하는 컷팅부를 포함하되, 상기 제1컷팅부 및 제2컷팅부는 상기 제1컷팅부 및 제2컷팅부에 각각 연결되어 상기 엔진부 후면에 연결되고, 각도를 조절하는 각도 조절실린더를 포함하고, 상기 각도조절실린더로 상기 제1컷팅부 및 제2컷팅부의 각도를 조절하고, 컷팅 깊이를 조절할 수 있도록 이루어져 있다.As another example, a road cutter, registered in Patent No. 10-2133652, has been devised, which includes a main body having front and rear wheels installed, a tank provided on the front side of the main body, an engine provided on the rear side of the main body, and a cutting section that receives power from the engine to rotate and includes a first cutting section and a second cutting section provided on the left and right sides of the rear side of the main body, wherein the first cutting section and the second cutting section are respectively connected to the first cutting section and the second cutting section and are connected to the rear side of the engine section, and include an angle adjusting cylinder that adjusts an angle, and the angles of the first cutting section and the second cutting section are adjusted by the angle adjusting cylinder, and the cutting depth is adjusted.
그러나, 이러한 종래 기술은, 각도 조절실린더에 의해 제1컷팅부와 제2컷팅부의 각도가 조절될 때, 각도 조절실린더가 제1컷팅부와 제2컷팅부에 직접 연결되어 있기 때문에, 제1컷팅부와 제2컷팅부가 심하게 흔들거리게 되는 문제점이 있다.However, this conventional technology has a problem in that when the angle of the first cutting portion and the second cutting portion is adjusted by the angle adjusting cylinder, the first cutting portion and the second cutting portion shake violently because the angle adjusting cylinder is directly connected to the first cutting portion and the second cutting portion.
또한, 제1컷팅부와 제2컷팅부가 회전될 때 발생되는 회전진동이 제1컷팅부와 제2컷팅부에 직접 연결된 각도 조절실린더에 그대로 전달되기 때문에, 각도 조절실린더의 틀어짐 현상이 발생되어 장시간 사용시에 각도 조절실린더의 인출입 동작이 용이하지 못하게 됨에 따라 제1컷팅부와 제2컷팅부의 각도 조절이 제대로 이루어지지 않는 문제점이 있다.In addition, since the rotational vibration generated when the first cutting part and the second cutting part rotate is directly transmitted to the angle adjustment cylinder directly connected to the first cutting part and the second cutting part, the angle adjustment cylinder becomes misaligned, and the withdrawal/intake operation of the angle adjustment cylinder becomes difficult when used for a long time, so there is a problem in that the angle adjustment of the first cutting part and the second cutting part is not properly performed.
또한, 제1컷팅부와 제2컷팅부의 위치를 조절하여 제1컷팅부와 제2컷팅부 사이의 폭을 조절하는 수단이 제1컷팅부와 제2컷팅부가 각각 축설되는 스크류의 회전동작에 의해 이루어지기 때문에, 먼지가 심한 도로공사현장에서 먼지가 스크류에 쌓일 경우, 스크류가 제대로 회전되지 못하게 되어 제1컷팅부와 제2컷팅부의 위치 조절이 용이하지 못한 문제점이 있다.In addition, since the means for adjusting the width between the first cutting portion and the second cutting portion by adjusting the positions of the first cutting portion and the second cutting portion is achieved by the rotational motion of the screw on which the first cutting portion and the second cutting portion are respectively installed, there is a problem that when dust accumulates on the screw at a road construction site with a lot of dust, the screw cannot rotate properly, making it difficult to adjust the positions of the first cutting portion and the second cutting portion.
본 발명은 컷팅체의 승강 및 하강동작은 물론, 좌우 이동동작이 각각 실린더 동작에 의해 이루어지도록 하되, 컷팅체의 승강 및 하강동작은 물론 좌우 이동동작시에 컷팅체를 견고하게 지지하도록 하여 컷팅체의 유동을 방지하도록 하며, 컷팅체의 컷팅폭 조절이 쉽고 용이하게 이루어질 수 있도록 하며, 작업자가 본체에 탑승한 상태에서 컷팅체가 전진하면서 도로의 컷팅이 이루어지도록 한 도로 컷팅장치를 제공함에 그 목적이 있다.The purpose of the present invention is to provide a road cutting device in which the cutting body is raised and lowered and the left and right movement movements are each performed by a cylinder operation, the cutting body is firmly supported during the raising and lowering movements as well as the left and right movement movements of the cutting body to prevent movement of the cutting body, the cutting width of the cutting body can be easily and conveniently adjusted, and the cutting body moves forward while cutting the road while a worker is riding in the main body.

본 발명은 본체와 연결되는 지지체에 의해 제1컷팅체와 제2컷팅체가 각각 연결 구비되어 있음에 따라, 제1컷팅체와 제2컷팅체의 승하강 동작은 물론 좌우이동 동작시에 지지체에 의해 제1컷팅체와 제2컷팅체가 견고하게 지지될 수 있어 제1컷팅체와 제2컷팅체의 흔들거림과 유동을 방지할 수 있을 뿐만 아니라, 제1컷팅체와 제2컷팅체가 승하강실린더와 좌우이동실린더에 직접 연결되지 않고, 제1컷팅체지지프레임과 제2컷팅체지지프레임에 의해 연결됨에 따라, 제1컷팅체와 제2컷팅체의 회전동작 시 발생되는 회전진동이 승하강실린더와 좌우이동실린더에 전달되는 것이 최소화되며, 제1컷팅체와 제2컷팅체의 간격이 자유롭게 조절 가능하기 때문에 도로면에 대한 컷팅 폭을 공사현장에 맞도록 쉽게 조절하여 작업할 수 있으며, 제1컷팅체와 제2컷팅체의 승하강 동작 및 좌우 이동 동작이 유압에 의해 인출입되는 승하강실린더와 좌우이동실린더에 의해 동작되기 때문에, 작업자가 편리하고 용이하게 제1컷팅체와 제2컷팅체를 승하강 시키거나 좌우폭을 조절하여 작업할 수 있어 작업성은 물론 편의성이 크게 향상될 수 있으며, 무한궤도 바퀴에 의해 전진되는 본체에 작업자가 탑승하여 도로면 컷팅작업을 진행할 수 있기 때문에 작업자의 피로감을 최소화할 수 있다.According to the present invention, since the first cutting body and the second cutting body are respectively connected by a support connected to the main body, the first cutting body and the second cutting body can be firmly supported by the support during the raising/lowering operation as well as the left/right movement of the first cutting body and the second cutting body, thereby preventing the shaking and movement of the first cutting body and the second cutting body, and since the first cutting body and the second cutting body are not directly connected to the raising/lowering cylinder and the left/right movement cylinder, but are connected by the first cutting body support frame and the second cutting body support frame, the rotational vibration generated during the rotational operation of the first cutting body and the second cutting body is minimized from being transmitted to the raising/lowering cylinder and the left/right movement cylinder, and since the gap between the first cutting body and the second cutting body can be freely adjusted, the cutting width for the road surface can be easily adjusted to suit the construction site, and the raising/lowering operation and left/right movement of the first cutting body and the second cutting body Since the operation is driven by a hydraulically driven elevating and lowering cylinder and a left-right moving cylinder, the worker can conveniently and easily raise and lower the first and second cutting bodies or adjust the left-right width to work, which greatly improves workability and convenience. In addition, since the worker can ride the main body that is advanced by the caterpillar wheels and perform road surface cutting work, worker fatigue can be minimized.

이와 같이 이루어진 본 발명은, 상기 제1컷팅체(200)와 제2컷팅체(300)가 상기 지지프레임(110)에 대해 가로방향으로 좌우측 슬라이딩 이동됨이 용이하기 때문에, 제1컷팅체(200)와 제2컷팅체(3000의 간격 조절작업이 쉽게 이루어질 수 있다.The present invention, which is made in this manner, can easily adjust the gap between the first cutting body (200) and the second cutting body (300) because the first cutting body (200) and the second cutting body (300) can easily slide left and right with respect to the support frame (110).
즉, 본 발명의 상기 제1컷팅체(200)의 좌우 이동을 설명하면, 상기 지지프레임(110)에 일측이 고정된 제1좌우이동실린더(410)를 인출시키거나 인입시키면, 상기 제1좌우이동실린더(410)의 타측이 연결된 제1좌우이동연결브라켓(181)이 인출되거나 인입되는 제1좌우이동실린더(410)에 의해 밀리거나 당겨지게 되고, 이에 따라, 상기 제1좌우이동연결브라켓(181)이 상단에 구비된 제1하단힌지부(131)는 물론, 제1하단힌지부(131)와 일측이 힌지연결되는 상기 제1컷팅체지지프레임(140) 및 제1컷팅체지지프레임(140)의 타측과 연결되는 제1컷팅체(200)가 좌우측 방향으로 이동되면서 간격이 조절된다.That is, when explaining the left-right movement of the first cutting body (200) of the present invention, when the first left-right movement cylinder (410) of which one side is fixed to the support frame (110) is withdrawn or introduced, the first left-right movement connecting bracket (181) to which the other side of the first left-right movement cylinder (410) is connected is pushed or pulled by the first left-right movement cylinder (410) being withdrawn or introduced, and accordingly, the first lower hinge part (131) provided at the upper end of the first left-right movement connecting bracket (181), as well as the first cutting body support frame (140) of which one side is hinge-connected to the first lower hinge part (131) and the first cutting body (200) connected to the other side of the first cutting body support frame (140), move in the left-right direction, so that the gap is adjusted.

이에 따라, 상기 제1컷팅체(200)를 지지프레임(110)의 가로방향에 대해 좌우측으로 슬라이딩 이동시킴이 용이하여 상기 제2컷팅체(300)에 대해 제1컷팅체(200)의 간격 조절작업을 편리하게 진행할 수 있다.Accordingly, it is easy to slide the first cutting body (200) left and right with respect to the horizontal direction of the support frame (110), so that the spacing adjustment work of the first cutting body (200) with respect to the second cutting body (300) can be conveniently performed.
또한, 본 발명의 상기 제2컷팅체(300)의 좌우 이동을 설명하면, 상기 지지프레임(110)에 일측이 고정된 제2좌우이동실린더(420)를 인출시키거나 인입시키면, 상기 제2좌우이동실린더(420)의 타측이 연결된 제2좌우이동연결브라켓(182)이 인출되거나 인입되는 제2좌우이동실린더(420)에 의해 밀리거나 당겨지게 되고, 이에 따라, 상기 제2좌우이동연결브라켓(182)이 상단에 구비된 제2하단힌지부(133)는 물론, 제2하단힌지부(133)와 일측이 힌지연결되는 상기 제2컷팅체지지프레임(150) 및 제2컷팅체지지프레임(150)의 타측과 연결되는 제2컷팅체(300)가 좌우측 방향으로 이동되면서 간격이 조절된다.In addition, when explaining the left-right movement of the second cutting body (300) of the present invention, when the second left-right movement cylinder (420) of which one side is fixed to the support frame (110) is withdrawn or introduced, the second left-right movement connecting bracket (182) to which the other side of the second left-right movement cylinder (420) is connected is pushed or pulled by the second left-right movement cylinder (420) being withdrawn or introduced, and accordingly, the second lower hinge part (133) provided at the upper end of the second left-right movement connecting bracket (182), as well as the second cutting body support frame (150) of which one side is hinge-connected to the second lower hinge part (133) and the second cutting body (300) connected to the other side of the second cutting body support frame (150), move in the left-right direction, so that the gap is adjusted.
이 때, 상기 제2컷팅체지지프레임(150)에 구비된 제2컷팅체힌지부(151)와 하측이 힌지연결되는 제2승하강실린더(170) 역시 제2컷팅체지지프레임(150)과 동일하게 좌우측 방향으로 슬라이딩 이동된다.At this time, the second cutting body hinge part (151) provided on the second cutting body support frame (150) and the second lifting and lowering cylinder (170) whose lower side is hinge-connected also slide in the left and right directions in the same way as the second cutting body support frame (150).
