Description

Technical Field

[0001] The invention relates to the technical field of cable traction, and in particular to a device for installing, traction and laying a power cable. Background Art

[0002] Power cables are cables used to transmit and distribute electrical energy. They play a vital role in the power system, transmitting electrical energy from the power plant to the user end. Power cables are usually composed of conductors, insulation layers, shielding layers and protective layers.

[0003] Most cables in cities are installed underground. Generally, it is necessary to bury underground pipes in advance, fix one end of the cable to be installed with a rope, and then manually pull the rope to install the power cable in the underground pipe. When the cable is pulled to the appropriate position, other cables can be connected and installed.

[0004] Through searching, we found CN222365998U, which discloses a power cable installation and traction device, belonging to the field of cable traction technology, including a box, a collar fixedly arranged on one side of the box, the inner cavity of the collar is hollowed out, a circular groove is provided in the inner cavity of the collar, a limit plate is fixedly installed on the inner wall of one side of the circular groove, an adaptable disc is slidably arranged in the inner cavity of the collar, the inner cavity of the disc is hollowed out, teeth are installed on the circumference of the disc, a sliding groove adapted to the limit plate is provided on one side of the disc, and a brush for cleaning the surface of the power cable is installed in the inner cavity of the disc. The power cable installation and traction device solves the problem of slipping caused by dust and stone particles adhering to the circumference of the power cable, and improves the efficiency of laying the power cable.

[0005] However, the problem encountered in practical applications is: due to the small space of the underground pipeline, the devices in the prior art are not convenient for entering the underground pipeline to work, and the power cables will still generate a large friction between the inner wall of the underground pipeline. At this time, it is more laborious and inconvenient to use manual traction to install the cables, and water stains and sand may also adhere to the surface of the cables. Manual pulling of the power cables will still cause slippage. Therefore, we propose a power cable installation traction laying device. Summary of the invention
