Description

Deconstruction cutting pulling apparatus of the underground power cable}

The present invention relates to an underground power cable removal, cutting and pulling device, and more particularly, when replacing a cable buried inside a pipeline, the buried cable is removed and cut easily, and at the same time, a newly constructed cable is removed. It relates to a pulling device for pulling and cutting underground power cables that are pulled to facilitate construction inside the pipeline.

In general, underground facilities are superior to ground facilities in terms of social and economic aspects such as stable supply of electricity, improvement in supply reliability, urban environment beautification, and safety, so the number of underground facilities continues to increase every year.

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

Cables installed inside such an underground conduit are usually supplied to the site in a state wound on a drum, and the length of the cable constructed at one time is approximately 250 to 300M. Or, 1 cable goes into 1 hole and 3 wires are called 1 line (for 3-phase alternating current).

Recently, as interest in the residential environment and urban aesthetics has increased, the underground project to improve the existing overhead distribution line into an underground distribution line is actively underway. Considering this, the existing cables will have to be removed and replaced with new cables within the next few years.

Currently, the cable removal (recovery) process is to pull it out with a cable puller using an electric motor and remove it. Accordingly, considering that one span of a manhole is 250 to 300M, it is a complicated and very difficult situation in which one section work is completed by repeating tying and untying about 80 to 100 times or more for demolition of one section.

Moreover, while cable removal work requires more work time than cable installation work, the construction cost is reflected by simply setting 50% of the new construction cost. Using the method of pulling it out on the side of the road and spreading it out, it is being demolished.

However, if the cable is pulled out and removed using a vehicle or heavy equipment, it can be effective in shortening the working time, but it is difficult to control the speed because the cable is pulled out at a high speed, so there is concern that it may damage other live cables in the manhole, As about 250~300M of cables have to be pulled out to the side of the road, the traffic control section becomes longer, and there are problems with the safety of passing vehicles and workers.

In addition, in order to recover the cable removed from the roadside, two people form a team to cut the removed cable while moving about 2 to 3 m with a large manual cutter. Due to the fact that communication is hindered, improvement of the cable removal process is required.

Accordingly, various technologies capable of automatically removing cables have been devised.

For example, a vehicle-mounted three-phase distribution cable automated removal device registered in Patent Registration No. 10-1031795 has been devised, which includes a housing forming a skeleton, a plurality of lower rollers rotatably provided in the housing, and an upper part of the lower roller. A retractor having an upper roller provided to be able to move up and down opposite to the upper roller, a hydraulic cylinder that lifts and lowers the upper roller and providing a pressing force to the upper roller, and a driving means for driving the upper roller or the lower roller, and a power distribution cable transfer A base plate formed to be slidable in a direction, a cutter part coupled to the base plate to be able to go up and down, a roller bed for supporting and guiding the distribution cable, upper and lower clamps provided on both sides of the roller bed, and the base It consists of a cutting table equipped with a transfer cylinder that reciprocates the plate in the horizontal direction.

This prior art allows the work time to be drastically reduced by taking out the cable inside the power conduit or pipe line with a winch, connecting it to the puller of the demolition device, and simultaneously cutting and tying the cable at the same time.

However, in the case of this prior art, there is a problem in that the configuration is inevitably complicated because the plurality of upper rollers guiding the removed cable to the cutting table side presses the cable while being pressed toward the lower roller side by each hydraulic cylinder.

Furthermore, since the retractor and the cutting table are provided independently and are connected by the retractor, the overall size is inevitably increased and it is not easy to move or store.

In addition, since it can be used only to remove the cable inside the conduit, there is a problem in that a pulling device for pulling the new cable must be additionally provided in order to install a new cable after the cable is removed, for example.
