Description

The complex power pulling apparatus of cable for underground}

The present invention relates to a ground power cable composite power pooling device, and more specifically, to complete the installation of the device for winding the ground cable only by moving the parking of the main truck equipped with the main power drum device around the manhole and newly ground the cable. In the case of burying in a new space, it is possible to bury new cables quickly in a small space, to quickly collect old underground cables and to automatically cut the cables at regular intervals and to install the waste wires in the vehicle. When retrieving for reuse, a separate cable retrieval drum unit is used to quickly wind the cables of A, B, and C three phases onto the drum, so that the drums can be detached and recovered. It relates to a cable composite power pooling device.

In general, when electric power is supplied to each home or factory site, electric poles were set up along the roads to supply electric power through long-term wires.

However, in the case of supplying electric power by installing electric poles on the side of the road as described above, it was not only aesthetically ugly due to the installation of the poles on the side of the road, but also had a problem of causing safety accidents due to the high voltage cable. There was also a problem of frequent complaints caused by conflicts with landowners.

Thus, in recent years, rather than the ground wire construction method of supplying electric power by establishing a pole, the underground distribution method of embedding electric wires in the ground is being activated day by day.

In other words, in order to install underground cables using the underground distribution method, the underground cable drum is loaded on a transport vehicle, then moved to the work site, and the cable drum is unloaded around the manhole, and the cable drum is wired using a crane. Mount on the drum die.

The underground winch for winding underground cables is to be installed in the manhole opposite the manhole on which the cable drum is installed, and the roller device is installed at the entrance of the corrugated pipe in the manhole so that the angle of the cable can be changed in the direction of 90 degrees when the cable is wound.

Next, unwind the rope wound on the underground underground winch cable drum and pass the 90 degree turning roller installed at the entrance of the corrugated pipe in the manhole, and place the errand bar inside the corrugated pipe buried between 50 ~ 400m between the manhole and the manhole. By connecting the anti-twist shackle or attaching the twist cable to the end of the new underground cable installed on the ground wire drum die with a pull grip, and then rotating the drum of the underground cable winch It is to bury new wire cable inside.

However, if the new cable is buried in the ground as described above, the cable winch is installed around the manhole, and in the place where the wire is released from the wire drum die on the opposite side, It had a problem of taking up a wide range of work places and a problem requiring a lot of manpower.

In addition, if the underground cable needs to be replaced due to the aging of the cable, the cable in the corrugated pipe buried in the ground should be recovered. However, when the old cable is recovered, a manual method of manpower is used to pull the old cable to the ground using an excavator to recover the old cable. When the old cable is recovered, the length of the cable buried in the ground This 50m ~ 400m long old cable to the ground using an excavator to pull the cable by 2m by manually cutting the wire by recovering the wire, not only takes a lot of time, but also takes up a lot of work places along the road traffic flow The problem that hinders this situation is highlighted.

In addition, when new apartments or factories are created around existing underground cables, new power consumers must be drawn to draw power between manholes and manholes. In this case, existing cables are high-quality cables and must be reused. Therefore, in order to recover the cable without damaging the underground cable, the cable should be laid on the road surface at 50m to 400m intervals around the manhole road. There was concern about damages, traffic control was inevitable, and a lot of manpower and time was consumed.

Accordingly, the present invention is to solve the conventional problems as described above, the wire drum die that is used in the wiring device for the distribution line of the separate wire cable mechanism method around the manhole, The cable drum die of the electric wire system was mounted on the vehicle and parked on the vehicle, and one axis was installed at the rear of the manhole of the vehicle equipped with the power drum device, and the rope was released from the auxiliary winch drum of the power drum device and wound 3 to 5 times on the power drum. Afterwards, the grounding cable is connected to the corrugated pipe in the manhole, and the underground cable is installed in the corrugated pipe.

In addition, when the old underground cable is to be recovered to replace the old underground cable, there is another purpose to allow the cable to be automatically cut at 2m intervals and mounted on the truck while the old cable is quickly recovered.

In addition, when new apartments or factories are created around existing underground cables, and new high voltage power consumers are created, when the existing high quality cables are recovered for reuse, A, B, C can be installed through a separate underground cable recovery system. Another purpose is to allow the cable to be recovered after rapidly winding the cable in a three-phase wire drum.

In addition, when recovering closed wires and high-quality cables, we developed a separate 90-degree directional guide tube connected to the corrugated pipe and the ground winch in the manhole and installed between the inlet of the manhole and the corrugated pipe. When the wire cable is pulled out, the 90-degree turning roller for wire cannot be used, so the 90-degree bend that is gently bent in order to prevent damage caused by peeling of the wire or sharp bending of the wire for the collection of the waste wire and the good cable There is also the purpose of developing and providing new guide tubes.

There is also an effect that can be quickly recovered.

In addition, when reclaiming the existing high-quality cable for reuse, it is possible to recover the cable while winding it on the drum while rapidly winding the three-phase wire cable to the drum through a separate cable recovery drum device truck. By doing so, there is an effect that the good cable can recover the re-usable underground cable.

In addition, when recovering the waste wire and the high-quality cable, a separate guide tube is installed between the inlet of the manhole and the corrugated pipe, so that the main power drum on the ground turns 90 degrees when the waste wire and the high-quality cable are drawn out. It is possible to prevent the damage caused by peeling of the coating or sharp bending of the wire in advance, so that the waste wire can be easily recovered, and the high-quality wire cable can be reused without damage.

As described above, it is economically effective because the grounding cable is newly installed with one piece of equipment and the waste wire is recovered and cut and used in combination to reuse the good cable.
