Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of train disassembly and assembly equipment, specifically an auxiliary tool for disassembling the windows of a high-speed train carriage. Background Technology
[0002] According to the maintenance requirements, all the windows of the high-speed train carriages need to be removed. The window glass is fixed with aluminum alloy frames, which are bolted to the car body. To prevent rain leakage during operation, the gaps between the aluminum alloy frames and the car body are filled with waterproof structural adhesive. During the disassembly of the windows, the waterproof structural adhesive in the gaps between the aluminum alloy frames and the car body needs to be removed with a glue cutter. Then, the bolts connecting the aluminum alloy frames and the car body need to be removed. Because the waterproof structural adhesive remains at the bolt holes and edges of the aluminum alloy frames during window installation, it creates significant tension during disassembly. This necessitates using pry bars to remove the aluminum alloy frames, which can easily damage them. The scrap rate of the aluminum alloy frames during window disassembly can reach 10%, and the disassembly requires multiple people working together, resulting in high labor costs and significant manpower and material consumption, thus increasing the maintenance costs of the carriages.
