Special tool for laser cutting of overhead line suspension

Abstract

A special tool for overhead line hanging object laser cutting comprises a trolley; a rotary disc is arranged on the trolley; a laser is arranged on the upper surface of the rotary disc; the external side of a laser lens of the laser is connected with a casing; a position of the casing, which is arranged at a laser lens position, is provided with a through hole; a position inside the casing, which is arranged on one side of the through hole, is provided with a guiding column; a focusing lens is arranged inside the casing; one side of the focusing lens is provided with a first motor; a transmission shaft of the first motor is connected with a first screw; the other side of the focusing lens is provided with a first nut. When the special tool for overhead line hanging object laser cutting is applied to de-icing operation, the first motor drives the first screw to rotate to enable the size of laser spots of the laser to get larger to enable ice blocks to be melted uniformly and an electric wire is avoided from burning out caused by excessively small laser spots of the laser. When the special tool for overhead line hanging object laser cutting is applied to sundry removing, the first motor drives the first screw to rotate to enable the size the laser spots of the laser to get smaller and sundries are cut through the laser spots.

Description

technical field [0001] The invention relates to a special tool for cutting, in particular to a special tool for laser cutting overhead line suspensions. Background technique [0002] In the maintenance work of power transmission and transformation equipment, sometimes there are many suspended obstacles on the transmission line caused by severe weather such as strong wind and cold air, or the line is covered with ice, which seriously affects the safe operation of the transmission line. To remove these suspension obstacles and icing on the lines, construction workers need to climb the tower and route the lines for manual cleaning, which makes the maintenance workers labor-intensive and dangerous. The existing special tools for laser cutting overhead line suspensions only have the deicing function, and the laser cannot be adjusted in focus. During the deicing process, it is very easy to damage the insulating layer of the overhead line due to the high temperature of the laser s...
