Description

Technical Field

[0001] The utility model relates to the technical field of EMU maintenance, in particular to an EMU intermediate coupler disassembly and assembly device. Background Art

[0002] With the development of transportation, more and more people travel by train. During the maintenance of EMU, the coupler between two carriages needs to be disassembled and assembled. The coupler installed at both ends of each carriage is large in size and weight. The coupler is cylindrical and weighs about 100 kilograms, which makes it difficult to disassemble and assemble.

[0003] At present, when removing the hook, the hook is generally supported by a forklift before disassembly. First, place the storage tooling of the hook on the forklift, raise the fork until the storage tooling is about 10 cm away from the lower edge of the hook, adjust the position of the storage tooling so that the groove of the storage tooling is directly below the hook, raise the fork so that the groove of the storage tooling fully supports the hook, and finally remove the fastening bolts between the hook and the body, and use a forklift to remove the hook and tooling as a whole after the two are completely disconnected. Due to the limited number of large equipment such as forklifts, it is difficult to meet the needs during the peak maintenance period. In addition, the operator is restricted by the qualifications of forklift driving and cannot perform maintenance work in time, which reduces the efficiency of disassembly and assembly and increases the cost of disassembly and assembly. In addition, due to excessive reliance on forklifts during disassembly and assembly, it is difficult to fine-tune the distance between the hook mounting seat and the body by forklift, and there is a risk of collision between the hook and the body.

[0004] Therefore, we propose a device for disassembling and assembling the intermediate coupler of an EMU. Utility Model Content
