Horizontal circuit breaker dismounting auxiliary device

Abstract

The invention relates to a horizontal circuit breaker dismounting auxiliary device, which comprises: a moving trolley; a lifting mechanism which comprises a lifting assembly and a lifting table, wherein the lifting table is connected to a moving trolley through the lifting assembly; a rotating mechanism which comprises a supporting frame and a rotating part, wherein the supporting frame is connected with the lifting table, the rotating part is rotationally connected with the supporting frame, the supporting frame is used for supporting a circuit breaker, and the rotating part is used for being arranged between the supporting frame and the circuit breaker and is used for being in rolling fit with the circuit breaker. According to the horizontal circuit breaker dismounting auxiliary device, the circuit breaker is always kept in a horizontal posture in the mounting process, shaking and toppling of the circuit breaker are avoided, the stability of the circuit breaker in the transportation process is guaranteed, the circuit breaker can rotate on the supporting frame through the rotating part on the supporting frame, and therefore, the problems of overturning of the circuit breaker and alignment in the mounting process are solved; and the lifting assembly is beneficial to greatly reducing the labor intensity and ensuring the working safety at the same time.

Description

technical field [0001] The invention relates to the technical field of substation equipment, in particular to an auxiliary device for disassembling and assembling a horizontal circuit breaker. Background technique [0002] At present, the GIS room of the UHV converter station is compactly arranged. The indoor space of the GIS is small. Nearly one-third of the circuit breaker mechanism has a steel frame in front of it, and nearly half of the circuit breaker mechanism has a GIL pipeline directly above it. If there is frequent suppression, etc. When the defect requires emergency replacement of the mechanism, the existing conditions on the site are difficult to meet. The narrow space makes it difficult to realize the original forklift operation method in the station, and the steel frame and GIL pipeline make the on-site aerial crane unable to meet the disassembly and assembly work of the hydraulic mechanism. When urgent mechanism replacement and maintenance are needed, there is...

AI Technical Summary

Problems solved by technology

However, the crane shakes severely during disassembly and assembly. During the hoisting process, due to the heavy circuit breaker mechanism, the circuit breaker cannot be rotated for hole alignment. A large amount of manpower is required for alignment, and there is a risk of falling

When a forklift is used for auxiliary dismantling of the circuit breaker, the positioning accuracy of the forklift is poor, and the circuit breaker is easy to shake and fall during the transportation process, and it is difficult to avoid damage during the operation; some circuit breakers are equipped with iron frames in front. Aerial cranes and forklifts cannot lift and disassemble the circuit breaker, and currently only rely on manpower
