Automatic cleaning device dedicated for bullet train insulator

Abstract

The invention belongs to the technical field of machinery, relates to maintenance equipment for high-speed railway bullet trains and specifically relates to an automatic cleaning device dedicated fora bullet train insulator. The automatic cleaning device comprises a clamping base, wherein a groove matched with an insulator seat in shape is formed in the clamping base; a cleaning cylinder is fixedin the groove; the cleaning cylinder consists of a fixed semicircular cylinder fixed in the groove and a movable semicircular cylinder movably connected to the fixed semicircular cylinder; the fixedsemicircular cylinder and the movable semicircular cylinder each comprise a semicircular shell and a semicircular liner located on the inner side of the shell; each liner and the corresponding shell are connected by a rotatable device; a cleaning apparatus is disposed on the inner side of each liner; at least one power gear shaft is disposed between each liner and the corresponding shell; gear teeth matched with a gear on each power gear shaft are disposed on the outer wall of the corresponding liner; and the power gear shafts are rotatably fixed on the clamping base. The automatic cleaning device provided by the invention has the beneficial effects that manual output during cleaning is reduced and cleaning efficiency is increased through above automatic cleaning processes.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to high-speed train maintenance equipment, in particular to a special automatic cleaning equipment for train insulators. Background technique [0002] As a kind of electrical equipment for the electric traction locomotive to obtain electric energy from the catenary, the high-speed train is installed on the roof of the locomotive or the train. The pantograph is composed of slide plate, upper frame, lower arm, underframe, bow spring, transmission cylinder, supporting insulator and other components. During the high-speed running of the motor car, the pantograph is in contact with the high-voltage voltage and receives electricity and friction, which is easy to ionize and generate a large amount of metal ions, which are deposited on the surface of the insulator used for insulation during the running process. After the metal ions are deposited on the surface of the insulator, it may form ...

AI Technical Summary

Problems solved by technology

During the high-speed running of the motor car, the pantograph is in contact with the high-voltage voltage and receives electricity and friction, which is easy to ionize and generate a large amount of metal ions, which are deposited on the surface of the insulator used for insulation during the running process. After the metal ions are deposited on the surface of the insulator, it may form into flakes The metal film covering the surface of the insulator reduces the insulation performance of the insulator. During the driving process, these metal films are likely to cause arcs between the high-voltage wires and form a safety hazard.

[0003] At present, manual scrubbing is used to scrub the metal film on the surface of insulators, which is labor-intensive, takes a long time to scrub, and the scrubbing effect is unstable.
