Description

Cable Multi Pulling Device

The present invention relates to a cable multi-pulling device, and more particularly, to a cable multi-pulling device for efficiently withdrawing the cable embedded in the power outlet or pipeline, and the stripping and cutting of the cable to be drawn out continuously. .

In general, underground facilities are superior to ground facilities in terms of social and economic aspects such as stable supply of electric power, improved reliability of supply, beautification of urban environment, safety, etc., and underground facilities are continuously increasing every year.

These underground facilities consist of underground pipelines, manholes buried on both sides of the pipelines, and cables installed in the pipelines between the manholes and the manholes, and transformers or switchgear are located at branch points or power supply points.

The cable installed inside the underground pipeline is usually supplied to the site in the state of being wound on the drum, and the length of the cable that is installed at one time is about 250 to 300M. Three strands are called one line (for three-phase alternating current). For example, a cable wound on a drum may be moved to an underground pipeline or to the ground, and then installed by loosening the cable.

In addition, underground cables installed in pipelines need to be replaced sequentially for safety by inspecting the construction of the 1st new city in the 1990s. In addition to the difficulties in the cable demolition process, the methods for recycling the removed cables' resources are sought. I have to do it.

Typically, the apparatus for recovering the cable by the contractor is Republic of Korea Patent No. 10-0590852 "wire winding device" and Patent No. 10-0697324 "engine driving hydraulic wire winding device" and Patent No. 10-0921984 "wire A recovery winding device "has been proposed, and these devices have been recovered by winding a cable by rotating the winding drum by hydraulic pressure supplied from a car crane.

The cable wound around the winding drum is usually moved to a material warehouse, stored for a certain period of time, and then sold to a recycling company for reprocessing. At this time, the cable to be discarded, which has been transported and stacked several times, will be reclaimed by the reprocessing company and only copper will be recycled.

Current cable demolition (recovery) process is to pull out the cable puller (cable puller) using an electric motor to remove. In this method, the tie and pull are repeatedly carried out in a narrow manhole, and the cable is cut and dismantled out of the manhole about 3m at a time. Considering that the manhole is 250 ~ 300M, it was a complicated and very difficult task to complete the section work by repeating the bundle and loosening at least about 80 ~ 100 times in order to demolish one section.

Therefore, while the demolition work requires more work time than the new cable work, the construction cost is simply reflected in the new construction cost by 50%, and in actual sites, heavy equipment such as crane vehicles or backhoes are used rather than cable pullers. It is pulled along the roadside by the road and extended to demolish.

The removal method using the vehicle or heavy equipment is effective for shortening the working time, but it is difficult to control the speed because it is pulled out at a high speed, which may damage other live cables in the manhole, and the cable of about 250 ~ 300M The traffic control section is lengthened and the traffic vehicle and worker safety are also a problem because it has to be pulled to the ground road side.

In order to recover the cables removed from the side of the road, two people became a pair and cut the removed cables while moving about 2-3m by a large manual cutter.These cables were tied together by dozens of cargo cranes for transportation to the vehicle. Withdraw the car after loading.

The cable demolition process is a situation that requires the improvement of the cable demolition process work because the lane of about 250 ~ 300M is continuously controlled during the pull, pull out, cutting, bundling, and loading of the cable. .

Therefore, there is a need for a new device that can immediately dismantle the cable to be removed in the field without going through a series of manual processes.

In order to solve the above problem, Republic of Korea Patent No. 10-1031795 has been proposed a vehicle-mounted three-phase distribution cable automated demolition device. The dismantling device draws out the cable inside the electric power port or pipeline to the winch and connects it to the retractor of the dismantling device and simultaneously cuts and bundles the work, thereby greatly reducing the working time, thereby relying on manpower. By automating the work, it was proposed to reduce labor costs and significantly reduce construction costs.

However, the retractor of the demolition apparatus is a method of pressing the cable disposed between the upper roller and the lower roller by pressing with the help of the hydraulic cylinder and then driving the hydraulic motor to pull the cable when rotating the upper roller and the lower roller. Since the weight of the cable itself installed at a length of ˜300M is very large, the rotational pressing force for pulling out only a part of the circumference of the upper roller and the lower roller in contact with the cable is insufficient, and the outer skin of the pressed portion is torn. It is impossible to pull out the cable because the rotational force is not applied. To solve this problem, dozens of upper rollers and lower rollers can be installed to increase frictional force for movement, but this increases the manufacturing cost and increases the size of equipment. Mobile tasks and management also have very difficult problems.

Therefore, the present invention has been made to solve the problems of the conventional underground cable recovery pooling device, but to pull the multi-line cable at the same time, by improving the towing unit for pulling the cable in a linear reciprocating motion method safely and efficiently It is an object of the present invention to provide a cable multi-pulling device that can be expected to reduce work time and improve workability by pulling cables out.

In addition, the present invention is to improve the workability and the improvement of workability by improving the structure so that when cutting the cable by a certain length in a straight reciprocating movement is made at the same time cutting the outer shell for stripping and a predetermined length for transporting. The object is to provide a cable multi-pulling device.

Cable multi-pulling device of the present invention is mounted on the vehicle or mounted on the road side ground to recover the cable, the vertical wall is fixed in the longitudinal direction spaced apart in the upper portion of the base body; An L guide comprising a rail fixed to an upper end of the vertical wall and a block fixed to a support plate of a cable traction part; The towing unit includes a pair of first clamping devices and a second clamping device, wherein the first clamping device and the second clamping device have a semi-circular lower part for fixing a block of the LM guide to the bottom and crimping a cable to the upper part. A support plate on which the mold is fixed, a pillar having a lower end fixed in a vertical direction on all sides of the support plate, a pressure plate on which a semicircular upper mold for crimping a cable on the bottom surface is fitted while all four sides are fitted so as to be movable along this column, and an upper portion of the pressure plate. A hydraulic cylinder having an operating shaft connected to and swinging the support shaft and a support plate fixed to the top of the column while mounting the hydraulic cylinder; The first clamping device and the second clamping device are respectively spaced apart by a length to move and fixed to the upper portion of the vertical wall with the help of the block of the L guide guide fixed to the bottom plate of the first clamping device and the second clamping device Technical features comprising a first hydraulic cylinder and a second hydraulic cylinder having an operating shaft fixed to the bottom of each support plate so that the first clamping device and the second clamping device can be moved forward or backward along the rail simultaneously or independently.

According to the present invention, in recovering the underground cable, the first clamping device and the second clamping device, which constitute a pair, simultaneously move the crimped cable and pull out the cable, followed by the first clamping device and the second clamping device. It is very safe and efficient to operate by the straight reciprocating method of the towing part which is carried out by the length which is easy to carry the bundle while holding the cable at all times by the repeated operation of releasing the crimping state and staggering the crimping state when returning to The cable can be pulled out, which reduces the work time by reducing work time and improving workability.

In addition, the present invention assists withdrawal of the initial cable as a winch, and facilitates the recovery of the cable by guiding the cable drawn out from the manhole to the towing unit reliably, helping to peel off the outer sheath of the cable with no power or power in the cutting unit It is very safe and efficient by cutting to the length that can be delivered in bundles, so the work time can be shortened and workability can be improved to reduce the construction cost.

First, the vertical portion fixed in the longitudinal direction while being spaced apart on the upper portion of the base body 1 so that the towing portion 3 is seated to provide a moving distance for holding the cable 10 drawn out from the manhole and reciprocating. The wall 11 is provided. The winding drum 51 of the winch 5, which will be described later, is disposed between the vertical walls 11, and the first hydraulic cylinder 4a and the second hydraulic cylinder 4b for operating the towing unit 3 are disposed. To provide space for

And the LM guide 2 to help the movement of the traction unit 3 is composed of a rail (21) and the block 22 is inserted into the rail 21 to move, the rail 21 is a vertical wall (11) It is fixed to the top of the block 22 is fixed to the bottom surface of the support plate 31 of the towing unit (3).

On the other hand, the traction part 3 must always hold the cable 10 when repeatedly pulling the cable 10 drawn out of the manhole by a predetermined length, and at the same time, the cable 10 is crimped, moved, and then returned to each other when moving. The first clamping device 3a and the second clamping device 3b are divided to form a pair so as to alternately release and maintain the gripping state. It is noted that the moving distance for pulling the cable 10 withdrawn from the manhole by the towing unit 3 is preferably about 2M, which is easy to carry after bundle cutting, but the present invention is not limited thereto.

In addition, the first clamping device (3a) and the second clamping device (3b) of the towing unit 3 is arranged and operated in the vertical wall 11 spaced apart by a moving distance equal to a length suitable for carrying a bundle. It is made of the same configuration. Therefore, when looking at the configuration of the base plate 31, the base plate 31 is fixed to the block 22 of the L guide (2) fixed to the bottom and the semi-circular lower mold 32 for crimping the cable 10 on the top, and the base plate 31 everywhere Column 33 fixed to the bottom in the vertical direction, and the pressing plate is fixed to the semi-circular upper mold (32 ') for crimping the cable 10 on the bottom while the four sides are fitted so as to move along the column 33 ( 34) and a hydraulic cylinder 35 having an operating shaft 35 'connected to the upper portion of the pressure plate 34 to move up and down, and a support plate fixed to an upper end of the column 33 while mounting the hydraulic cylinder 35.
