Description

Deconstruction cutting pulling apparatus of the underground power cable}

The present invention relates to an apparatus for cutting and pulling underground power cables, and more particularly, to a disconnection, cutting and pulling apparatus for underground power cables, in which, when replacing cables buried inside a conduit, the buried cable is removed and cut easily, and at the same time, a newly constructed cable is pulled to facilitate installation inside the conduit.

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. Due to the electrical characteristics, 3 cables are inserted into 1 conduit or 1 cable is entered and 3 strands are called 1 circuit (for 3-phase alternating current), and the cable wound on the drum is moved to the inside of the underground conduit and then installed while unwinding the cable.

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 currently actively progressing, and the underground power facility will increase rapidly in the future.

Currently, the cable removal (recovery) process is to be pulled out and removed with a cable puller using an electric motor. This is done repeatedly in a narrow manhole by bundling and pulling, and when about 3m of cable comes out of the manhole at a time, it is cut and removed. 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 must be repeated about 80 to 100 times or more to remove one section.

Moreover, while the cable removal work requires more work time than the cable installation work, the construction cost is simply set at 50% of the new construction cost, and is reflected in the actual site.

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, and there is a risk of damaging other live cables in the manhole. As the cable of about 250 to 300M must be pulled out to the side of the ground, the traffic control section becomes longer, and there is a problem 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. As a result, a road of about 250 to 300 M is controlled by the cutting of the cable, which interferes with traffic flow, and the cable removal process needs improvement.

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

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