AI Technical Summary

Technical Problem

In traditional live wire stripping operations, metal tools are difficult to control the embedded depth, easily damage the wire core conductor or cannot completely peel off the insulation layer, affecting the life of the wire and construction safety.

Method used

The laser wire stripping tool is used to perform non-contact cutting using the thermal effect of the laser. The cutting seams are processed in the insulating layer through the feeding motion, circumferential rotation motion and linear motion of the laser head, and the insulating layer and the wire core are embedded in the cutting seams with a knife.

Benefits of technology

The insulating layer is stabilized and completely peeled off, which avoids damage to the wire core conductor, improves the wire stripping accuracy and safety, and reduces the impact on the wire life.

Abstract

The invention relates to the technical field of electric power facility maintenance, in particular to a distribution network hot-line work laser wire stripping tool and a working method.A mechanical arm carries the tool to reach a wire stripping work area and moves in the axis direction of a cable; the tool body comprises at least one set of laser emitting units evenly distributed in the circumferential direction of a cable, all the laser emitting units are driven by a laser head driving unit to synchronously move towards the cable, and the laser head driving unit is driven by a rotating unit to rotate around the axis of the cable. The laser emitting unit comprises a limiting seat connected with the sliding block, the limiting seat is clamped on the outer side of the laser seat and is in sliding connection with the laser seat, the limiting seat is connected with a shifting knife limiting seat, a first spring is arranged between the laser seat and the limiting seat, a shifting knife in sliding connection is arranged in the shifting knife limiting seat, and a second spring is arranged between the shifting knife limiting seat and the shifting knife; and a gas outlet is formed in the other end of the laser seat. And a non-contact cutting mode aiming at the insulating layer is formed by laser, so that the probability of conductor damage is reduced.
