Description

Technical Field

[0001] The invention relates to the field of automated maintenance equipment, in particular to automated disassembly and assembly maintenance equipment for rail transit lithium titanate battery modules. Background Art

[0002] China's existing rail transit vehicles are gradually transitioning from the overhead power supply mode to the self-contained energy storage system power supply mode, and the energy storage system serves as the power source of rail transit vehicles. At present, most rail transit-related energy storage systems are lithium titanate batteries, which are installed under the vehicle. The system mainly consists of multiple lithium titanate battery modules for energy storage, and the lithium titanate modules are arranged horizontally as a whole. In the later stage of maintenance and repair, the lithium titanate battery module needs to be disassembled and assembled, which currently requires manual disassembly. Since the weight of the lithium titanate battery module is generally between 70kg and 200kg, this weight is generally not enough for one or two adults to disassemble and assemble. Due to the limited on-site maintenance space, manual disassembly is also a relatively large safety risk, and the maintenance time is long, which affects the normal driving of the vehicle. Summary of the invention

[0003] In view of the defects existing in the prior art, the purpose of the present invention is to provide an automatic disassembly and maintenance device for rail transit lithium titanate battery modules.
