Description

Technical Field

[0001] This utility model belongs to the field of inspection and maintenance technology, specifically relating to a device for disassembling protective covers. Background Technology

[0002] As urban rail transit lines age, contact rails and related equipment gradually enter their overhaul period. During overhauls, the protective covers on high-voltage contact rails often become overly tight due to temperature changes and the inertial force of the current collector shoes, making manual removal difficult. Currently, there are no specialized tools available for removing these protective covers. Therefore, maintenance personnel typically use screwdrivers, but this method has significant drawbacks. Slight carelessness during removal can damage the protective covers, severely impacting the quality and efficiency of the overhaul. Furthermore, using screwdrivers increases the risk of injury to maintenance personnel due to the unstable nature of the process.

[0003] Currently, there is a lack of a device for removing the protective cover to solve the problem of the difficulty in removing the protective cover on the contact rail.

[0004] Therefore, a new technology is needed to address the lack of a device for disassembling the protective cover in existing technologies. Utility Model Content
