Power cable stripping device

Abstract

The invention belongs to the technical field of power equipment, and particularly relates to a power cable stripping device which comprises a workbench, a cutting unit and a heating unit. A cable body penetrates through the middle part of the cutting unit, and the cable body comprises an insulating layer and a conductive core; the heating unit comprises a heating table and a high-frequency heating coil, the high-frequency heating coil is connected with a power supply through a high-frequency generator, and the high-frequency heating coil and the cable body are coaxially arranged; the cutting unit comprises a cutting table, a driving roller and a driven roller, the driving roller and the driven roller are symmetrically arranged, and the cable body penetrates through a gap between the driving roller and the driven roller; the driven roller is rotationally connected with the cutting table, and the driving roller is driven by a gear motor. The middle part of the driving roller is fixedly connected with a disc-shaped cutter; after the cable body penetrates through the driving roller and the driven roller, the high-frequency heating coil heats the cable body, and then the cutter rapidly and stably cuts an insulating layer, so that damage to a conductive core caused by non-uniform cutting force application is reduced.

Description

technical field [0001] The invention belongs to the technical field of power equipment, in particular to a power cable stripping device. Background technique [0002] In power lines, the proportion of cables is gradually increasing. Power cable is a cable product used to transmit and distribute high-power electric energy in the main line of the power system; however, the traditional power cable stripping device has poor effect and low efficiency due to cumbersome and complicated design. [0003] There are also some technical solutions about cable stripping devices in the prior art. For example, a Chinese patent with application number 2018104015343 discloses a power cable stripping device, including that the device places the cable body in a downward pressure sequence from right to left. After the clamping block and the three cable rollers are mounted, start the first servo drive motor to drive the circular gear to rotate. According to the meshing principle of the rack and ...

AI Technical Summary

Problems solved by technology

[0006] In order to make up for the deficiencies of the prior art, when the cable is docked or repaired outdoors in the prior art, the skin insulation layer of the cable body is cut by a cutter, but since the insulation layer is usually tightly wrapped in a conductive On the outer periphery of the core, it is difficult to peel off the insulation layer completely and without adhesion by a cutter, resulting in low cable stripping efficiency. At the same time, the hardness of the cable insulation layer is high under low temperature conditions. It is time-consuming and laborious to peel off by a cutter, and the cutting force is difficult to control. The problem of easily damaging the conductive core, a power cable stripping device proposed by the present invention
