Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable harness,

More particularly, the present invention relates to an apparatus for removing and cutting cables in a power port or a pipeline while efficiently withdrawing the cables, And a device for removing and installing the underground power cable.

In general, underground facilities are superior to ground equipment in terms of stable supply of electricity and reliability of supply, urban environment beautification, safety and social and economic aspects.

These underground facilities consist of a pipeline buried in the ground, a manhole embedded in both sides of the pipeline, and a cable newly installed in a channel between the manhole and the manhole, and a transformer or switch is located at a branch point or a power supply point.

The cable installed inside the underground channel is usually supplied to the site while being wound around the drum. The length of the cable to be installed at one time is about 250 to 300M. Due to its electrical characteristics, three cables Three strands are called one line (for three-phase alternating current). For example, a cable wound around a drum is moved to the inside of the underground pipe or to the ground, and the cable is loosened and installed.

In addition to the first new city such as Ilsan, Bundang, and Pyeongchon which were developed in the 1990s, various projects related to balanced national development, administrative capital, and transfer of public corporations are being developed. In addition, And the underground electric power facilities are increasing rapidly.

In addition, recently, interest in residential environment and urban aesthetics has increased, and the undergroundization project to improve the existing distribution line to underground distribution line is actively being actively carried out, and the underground power facility will increase rapidly in the future.

In the meantime, underground cables installed in the construction of the new city in the 1990s were used for about 23 years. Considering 30 years of cable service life, it is necessary to dismantle them in the next few years and replace them with new cables.

Considering the situation in which a lot of underground cables must be replaced, the present general construction and demolition construction methods have the following problems.

First, the inefficiency of the work due to the repeating process, which is one line at the same interval where several lines are installed.

Second: non-economical due to repeated installation and demolition of cable drums.

Third: Insufficient information management of construction cable and poor reliability of construction quality.

Fourthly, there was a problem such as a pulling out of a demolition cable on a road side, a cutting, a bundling in a short distance, and a disconnection in a work car, and a deterioration in work efficiency due to a discontinuity.

For example, a device for recovering a cable by a construction company is disclosed in Korean Patent No. 10-0921984 entitled " Wire Winding Winding Winding Device ", Registered Patent No. 10-0978003 entitled " Vehicle Mounting Type Power Distribution Cable Automatic Winding Device " Registered patent No. 10-1027732 entitled " Multi-line cable pulling device for drum cable "and Registered patent No. 10-1261458" Underground cable multi-line pulling device "have been proposed. The drum was rotated to collect the cable.

The cable rolled up on the winding drum is usually stored in a material warehouse for a certain period of time and then sold to a recycling company for reprocessing. At this time, cables to be discarded after carrying out several times of transportation and demolition will be recycled only from copper by removing the jacket (insulator) from the reprocessing company.

Currently, the cable demolition (withdrawal) process is pulled out by a cable puller using an electric motor. This method is repeated in bundling and pulling in a narrow manhole, and when the cable comes out of the manhole about 3m at a time, it is cut and removed. Considering that the manhole span is 250 ~ 300M, the above process was complicated and very difficult work to complete the section work for repeating the binding and unraveling of about 80 ~ 100 times for one section demolition.

 Therefore, the demolition work requires more work time than the cable construction work, but the construction cost is only 50% of the new construction cost. Therefore, in the actual site, heavy equipment such as crane vehicle or backhoe And pulling it out along the roadside road and using it to unfold and extend it.

The removal method using the above vehicle or heavy equipment is effective for shortening the working time, but there is a fear that the speed control is difficult because it is pulled at a high speed, which may damage the live cable in the manhole. The roads are lengthened and the problem of road traffic and worker safety is also problematic.

In order to recover the cables that have been removed on the roadside, a pair of two people will be moved by about 2 to 3 meters with a large manual cutter to cut the broken cable. The cut cable is bundled up several tens of times to carry it back to the vehicle, To withdraw from the car.

The above-mentioned cable demolition process is required to improve the demolition process of the cable since the car is controlled by about 250 ~ 300M while the cable is pulled out, cut off, bundled up, .

Therefore, there is a need for a new device capable of immediately dismantling a cable to be removed on site without going through a series of conventional manual procedures.

Korean Patent No. 10-1031795 entitled " Vehicle Mounting Type Three Phase Distribution Cable Automatic Demolition Device "and Korean Patent No. 10-1147597 entitled " Underground Cable Composite Power Plum Pooling Device" The former demolition apparatus is a system in which a cable is pulled out by a winch, a cable is disposed between an upper roller and a lower roller, and a cable is pulled out through compression and rotation with the aid of a hydraulic cylinder, The pulling device of the pulling device is a device for pulling out a cable by using a winch rotated by a hydraulic motor and they are equipped with a cable cutter for convenience of recovering an old cable. However, since these cable cutters are fixed type, There is a problem that the operation time and the working time of the equipment are increased because the recovery cable can not be cut while simultaneously pulling the recovery cable.

In addition, the registered " cable multi-pulling device " filed and registered by the applicant of the present invention includes a first clamping device for pulling and temporarily stopping the withdrawal cable in a linear reciprocating motion, The recovery cable is pulled out more stably than the conventional recovery cable retracting method. However, the recovery cable can not be cut at the same time while continuously pulling the recovery cable, There is an uneconomical problem that the operation time and the working time are increased.

In addition, since the conventional devices for demolishing the recovered cable and installing new cables are all independently mounted on the vehicle, they are moved while moving. Therefore, in order to recover and install cables, two vehicles and two Since the number of drivers required is wasted, the workforce is wasted and the equipment mounted on the two vehicles must be used while replacing the equipment. Therefore, the work is troublesome and the cost is uneconomical.

Accordingly, the present invention relates to a demolition and installation apparatus for an underground power cable in which a grounding cable pulling portion and a new pulling portion are mounted together, And a pulling part and a pulling part are mounted together on the vehicle so as to newly install the two-line cable, so that the cable can be recovered and installed efficiently in a safe and efficient manner.
