Description

그리퍼 방식의 전선 포설장치Gripper-type wire laying device
본 발명은 전선 포설장치에 관한 것으로서, 보다 구체적으로는 선박의 케이블 트레이와 같이 작업자의 접근성이 불량한 장소에 경박단소의 구조로 설치되는 그리퍼 방식의 전선 포설장치에 관한 것이다.The present invention relates to an electric wire laying apparatus, and more particularly, to a gripper-type electric wire laying apparatus installed in a structure of light and thin in a place where a worker's accessibility is poor, such as a cable tray of a ship.
통상적으로 다심 구조의 피복된 전선을 포설하는 것은 많은 인원 투입을 요구하는 작업이지만 각종 포설 자동화 장치가 도입되면서 효율성이 점차 증대되고 있다. 그럼에도 불구하고 선박 및 해양플랜트와 같이 협소한 공간에 설치되는 케이블 트레이에 대한 전선포설 작업은 여전히 수작업에 의존하여 많은 작업인원이 필요하고 근골격계 질환을 유발하기 쉬워 작업의 효율성이 낮은 편이다.In general, the installation of the multi-core coated wire is a task that requires a lot of personnel input, but the efficiency is gradually increased with the introduction of various installation automation devices. Nevertheless, the wire laying work for cable trays installed in narrow spaces such as ships and offshore plants still depends on manual labor, which requires a large number of workers and causes musculoskeletal disorders.
전설포설 장치에는 전기/엔진/공압식 윈치류 포설기, 롤러/무한궤도/볼 형태의 풀러와 피더, 그리고 가이드로프를 견인하기 위한 로봇 등이 주로 사용되고 있다. 하지만 전술한 대부분의 장치는 무겁고 크기가 커서 주로 직선형의 넓은 전로에서 적절하다. 이에 작업공간이 협소하거나 곡선과 수직으로 이어지는 전로에는 적용이 곤란한 실정이다. Legendary installation devices include electric / engine / pneumatic winch spreaders, roller / tracking / ball pullers and feeders, and robots for towing guide ropes. Most of the devices described above, however, are heavy and large in size and are suitable for use in large, wide converters. Therefore, it is difficult to apply to a converter that has a narrow working space or runs perpendicular to the curve.
특히 선박이나 플랜트의 경우 대부분의 전로에 곡선과 수직 구간이 많아 새로운 형태의 케이블 포설 시스템이 필요하다. 이러한 시스템에 사용되는 장치는 소형, 경량, 고속, 고출력의 특성을 요한다.Especially for ships or plants, most of the converters have curves and vertical sections, requiring a new type of cable laying system. The devices used in these systems require small size, light weight, high speed and high power.
이와 관련하여 참고할 수 있는 선행기술 문헌으로서 한국 등록특허공보 제1205921호, 한국 등록실용신안공보 제0454764호 등이 알려져 있다. 전자에 의하면 견인부를 포함한 전장이 길어지므로 좁은 공간에 설치하기 곤란하다. 후자에 의하면 구조가 복잡화되므로 신뢰성과 내구성이 약화될 우려가 크다.In the related art, Korean Patent Publication No. 1205921, Korean Utility Model Publication No. 0454764, and the like are known. According to the former, since the overall length including the towing portion is long, it is difficult to install in a narrow space. According to the latter, since the structure is complicated, the reliability and durability are greatly deteriorated.

이하, 첨부된 도면에 의거하여 본 발명의 실시예를 상세하게 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 1은 다수의 트레이(110)(120)(130)를 지닌 전로 상에 전선(150)을 포설하는 시스템에 관하여 제안한다. 전로는 수평트레이(110), 수직트레이(120), 코너트레이(130)를 포함하여 구성된다. 선박과 플랜트에 있어서 전로는 협소하거나 다수의 직선과 곡선을 포함하는 긴 길이로 형성된다. 곡선의 전로는 코너트레이(130)를 비롯한 다수의 지점에 구성되기도 한다.1 proposes a system for laying wires 150 on a converter with multiple trays 110, 120, 130. The converter is configured to include a horizontal tray 110, a vertical tray 120, a corner tray 130. In ships and plants, converters are either narrow or formed into long lengths containing a number of straight lines and curves. The curve converter may be configured at a number of points including the corner tray 130.
본 발명에 따르면 상기 전로 상에 파지수단(300)이 배치된다. 파지수단(300)는 후술하는 구동수단(400)의 왕복운동시 파지와 파지해제를 자동으로 수행한다. 파지수단(300)을 도입하는 것은 협소한 전로에 설치가 용이한 점에 기인한다. 종래의 윈치류 포설기의 경우 주로 직선전로에 굵은 전력선을 포설할 때 사용된다. 매우 긴 전로에 케이블을 설치하는 경우에는 케이블과 전로의 마찰 때문에 마찰을 줄이기 위해서 주로 롤러 등을 함께 이용하지만, 그럼에도 불구하고 전선(150)에 매우 큰 장력이 작용하므로 전선(150)이 손상될 가능성이 높다. According to the present invention, the holding means 300 is disposed on the converter. The gripping means 300 automatically performs gripping and gripping release during the reciprocating motion of the driving means 400 which will be described later. Introduction of the holding means 300 is due to the ease of installation in a narrow converter. Conventional winch laying machine is mainly used to install a thick power line in a straight line converter. When the cable is installed in a very long converter, the roller and the like are mainly used to reduce friction due to the friction between the cable and the converter, but nevertheless, the wire 150 may be damaged because a very large tension acts on the wire 150. This is high.
특히나 곡선전로와 직선전로가 혼합된 경우에는 곡선전로 자체에도 매우 큰힘이 작용하게 되므로 파손의 위험이 높아 곡선전로가 혼합된 경우에는 윈치의 사용에 한계가 있다. In particular, when a curved converter and a linear converter are mixed, a very large force acts on the curved converter itself, so the risk of breakage is high. Thus, when the curved converter is mixed, the use of the winch is limited.
본 발명의 세부 구성에 의하면, 상기 파지수단(300)은 카형그리퍼(331), U형그리퍼(333), 풍선형그리퍼(335)에서 선택되는 조합을 사용하는 것을 특징으로 한다. 카형그리퍼(331)는 아암의 회동으로 전선(150)의 이동을 단속하고, U형그리퍼(333)는 U자밴드의 승하강으로 전선(150)의 이동을 단속하고, 풍선형그리퍼(335)는 공압으로 밴드의 팽창과 수축을 유발하여 전선(150)의 이동을 단속한다. 카형그리퍼(331), U형그리퍼(333), 풍선형그리퍼(335)는 소형화가 가능하여 협소한 트레이(110)(120)(130)에 설치가 용이하다.According to a detailed configuration of the present invention, the holding means 300 is characterized in that using a combination selected from the car gripper 331, the U-type gripper 333, the balloon-type gripper 335.

Therefore, the link 220 may move along with the wire by the action of the frictional force on the wire during the forward movement, and may reverse back separately from the wire during the backward movement. This one-way laying force is performed by a simple mechanical mechanism as described below, which is a simplification of the overall configuration.

To prevent this, a coating material 313 having a high frictional coefficient and abrasion resistance is added to the outer surface of the gripper 310. The coating material 313 uses at least one of air hose, vinyl, leather, fiber, and rubber, which are resin materials. Of course, it is not necessary to use the covering material 313 when the wire 150 is not concerned about damage.

따라서 작업자는 볼트(251)를 상하로 이동시켜 슬롯(105)에 일치되게 끼울 수 있게 된다.Therefore, the operator can move the bolt 251 up and down to fit in the slot 105.
이렇게 볼트(251)가 슬롯(105)에 끼워진 상태에서 케이블 트레이(100)의 배면에서 손잡이(252)를 볼트(251)에 체결함에 따라 트레이 클램프(180)의 장착이 완료된다.Thus, the mounting of the tray clamp 180 is completed by fastening the handle 252 to the bolt 251 at the back of the cable tray 100 in a state where the bolt 251 is inserted into the slot 105.
이와 같이 트레이 클램프(180)의 장착이 완료되면, 그리퍼(351, 352, 353)에는 포설하고자 하는 전선(150)이 삽입된다.When the mounting of the tray clamp 180 is completed as described above, the wires 150 to be installed are inserted into the grippers 351, 352, and 353.
다음 도 19 내지 도 21을 참조하여 본 발명의 바람직한 실시 예에 따른 수직 그립형 트레이 클램프가 케이블 트레이에 포설되는 상태를 간략하게 설명한다.Next, a state in which the vertical grip tray clamp is installed in the cable tray will be briefly described with reference to FIGS. 19 to 21.
본 발명의 트레이 클램프(180)가 케이블 트레이(100)에 일정한 높이 간격으로 설치된 상태에서 전선(150)을 삽입시킨다. 또한 케이블 트레이(100)에는 트레이 클램프(180) 사이에 전선(150)을 끌어당기는 케이블 포설 로봇(미도시)이 설치된다.The tray clamp 180 of the present invention inserts the wire 150 in a state in which the cable tray 100 is installed at a predetermined height interval. In addition, the cable tray 100 is provided with a cable laying robot (not shown) that pulls the wire 150 between the tray clamp 180.
즉, 케이블 포설 로봇은 전선(150)을 일정 길이만큼 당겨 주어 케이블을 포설되게 한다. 이러한 케이블 포설 로봇은 본 출원인에 의해 다수 출원된 '그리핑 방식의 전선포설 장치(특허출원번호 제10-2013-0114512호 참조)', '케이블 포설 시스템(특허출원번호 제10-2013-0098981호 참조)' 등을 사용하므로, 본 발명에서는 이에 대한 구체적인 설명을 생략하기로 한다.That is, the cable laying robot pulls the wire 150 by a predetermined length so that the cable is laid. Such a cable laying robot is a wire laying device of a gripping method (see patent application No. 10-2013-0114512), and a cable laying system (patent application No. 10-2013-0098981) And the like, '' a detailed description thereof will be omitted herein.
전선(150)은 케이블 포설 로봇에 의해 일정 길이만큼 상승하게 되며, 케이블 포설 로봇의 작동 중에 전선(150)의 상승이 일시적으로 정지된 상태를 유지하게 된다. 이때 전선(150)은 장착부(218)에 장착된 그리퍼(351, 352, 353)에 의해 낙하가 방지된다.The wire 150 is raised by a cable laying robot by a predetermined length, and the rising of the wire 150 is temporarily stopped during the operation of the cable laying robot. In this case, the wire 150 is prevented from falling by the grippers 351, 352, and 353 mounted on the mounting part 218.
도 19에 도시된 바와 같이, 아이 그리퍼(351)는 그리퍼 내측에 전선(150)이 위치하게 되고, 케이블 포설 로봇에 의해 일정 높이만큼 상승시키게 된다.As shown in FIG. 19, the eye gripper 351 is positioned with the wire 150 inside the gripper and is raised by a predetermined height by the cable laying robot.
케이블 포설 로봇은 일정 높이만큼 상승이 완료된 이후 전선(150)을 다시 상승시키기 위하여 일시적으로 정지할 때 전선(150)의 무게에 의하여 처짐(낙하) 현상이 발생하게 된다.When the cable laying robot temporarily stops to raise the electric wire 150 again after the ascending is completed by a certain height, sag (falling) occurs due to the weight of the electric wire 150.
이때 아이 그리퍼(351)는 전선(150)의 처짐 현상에 의해 아이 그리퍼(351)가 도면상 밑으로 젖혀지게 되어 전선(150)의 처짐을 방지하게 된다. 즉, 전선(150)은 아이 그리퍼(351)의 내면에 밀착된 상태를 유지하게 되고, 케이블 포설 로봇이 전선(150)을 상승시킴에 따라 전선(150)이 상승된다.At this time, the eye gripper 351 is prevented from sagging of the wire 150 because the eye gripper 351 is bent downward on the drawing by the deflection phenomenon of the wire 150. That is, the wire 150 is maintained in close contact with the inner surface of the eye gripper 351, and as the cable laying robot raises the wire 150, the wire 150 is raised.
그러나 전선(150)이 처지게 되면, 아이 그리퍼(351)가 밑으로 젖혀지면서 전선(150)을 트레이 클램프(180) 쪽으로 끌어당기게 된다. 이에 따라 전선(150)은 아이 그리퍼(351)에 의해 처짐이 방지된다.However, when the wire 150 sags, the eye gripper 351 is bent downward and pulls the wire 150 toward the tray clamp 180. Accordingly, the wire 150 is prevented from sagging by the eye gripper 351.
즉, 아이 그리퍼(351)가 도면상 밑으로 젖혀짐에 따라 전선(150)이 아이 그리퍼(351)에 긴밀하게 밀착(압착)되어 전선(150)의 처짐이 발생하지 않게 된다.That is, as the eye gripper 351 is flipped downward in the drawing, the wire 150 is closely adhered to the eye gripper 351 (compression bonding) so that the sagging of the wire 150 does not occur.
또한 벨트 그리퍼(352)는 대략 삼각형상으로 일정 길이를 갖는 벨트가 일 방향으로 회전 가능하게 설치되어 있다. 즉, 벨트 그리퍼(352)는 원웨이(one way) 베어링 등에 의해 벨트를 일 방향으로 회전된다. 이때 전선(150)은 다수의 벨트가 밀착되어 있다. 벨트는 전선(150)의 상승 시에 회전되고, 전선(150)이 처지게 되면 벨트는 전선(150)에 긴밀하게 밀착(압착)된 상태를 유지하게 되어 압착에 의해 전선(150)의 처짐을 방지하게 된다.In addition, the belt gripper 352 is provided so that a belt having a predetermined length in a substantially triangular shape is rotatable in one direction. That is, the belt gripper 352 rotates the belt in one direction by a one-way bearing or the like. At this time, a plurality of belts are in close contact with the wire 150. The belt rotates when the electric wire 150 is raised, and when the electric wire 150 sags, the belt is kept in close contact (compression) with the electric wire 150 to prevent sagging of the electric wire 150 by pressing. Will be prevented.
아울러 쐐기형 그리퍼(353)는 벨트 그리퍼(352)와 같이, 대략 등각 삼각형상으로 이루어져 있고, 삼각형의 각 변에는 일 방향으로 회전되는 롤러 또는 베어링 등이 일 방향으로 회전 가능하게 설치되어 있다.In addition, like the belt gripper 352, the wedge-shaped gripper 353 has an approximately equilateral triangle shape, and rollers or bearings that are rotated in one direction are rotatably installed in each side of the triangle.
즉, 쐐기형 그리퍼(353)의 롤러 또는 베어링 등은 일 방향으로 회전되며, 평상 시에는 전선(150)의 외면에 밀착되어 있다. 이에 따라 전선(150)의 상승 시에는 롤러 등이 회전되고, 전선(150)의 상승이 일시 중지된 상태에서 전선(150)이 처지게 되면 압착에 의해 전선(150)의 처짐을 방지하게 된다.That is, the roller or bearing of the wedge-shaped gripper 353 is rotated in one direction, and is usually in close contact with the outer surface of the electric wire 150. Accordingly, when the wire 150 is raised, a roller or the like is rotated, and when the wire 150 sags while the rise of the wire 150 is suspended, the sagging of the wire 150 is prevented by crimping.
