Embodiment Construction

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] The basis for the overhaul of the coupler buffer is the EMU overhaul process.

[0031] An overhaul line for coupler buffers, the overhaul line sequentially includes a cache area to be repaired 1, a decomposition inspection area 2, a flaw detection area 3, a paint repair area 4, an assembly test area 5, and a qualified product storage area 6 according to the maintenance process. There are suspension arms inside, which are used to drive the components to be transferred between each station, so that each station can be checked and repaired according to the beat and process. A plurality of three-dimensional storage racks are arranged in the buffer area to be repaired; a disassembly worktable 7, a coupler slow disassembly device 8, a coupler head disassembly device 9, a buffer crushing tube press 10 and a buffer press are provided in the disassembly inspect...

Description

technical field [0001] The invention belongs to the field of inspection and maintenance of close-connected coupler buffers, and in particular relates to a coupler buffer inspection line and inspection method for decomposing, detecting, cleaning, assembling and testing the couplers and buffers of various types of EMUs. Background technique [0002] The coupler buffer is one of the most basic and important parts of the vehicle, which is used to connect the vehicles in the train to keep a certain distance from each other, and to transmit and alleviate the longitudinal force and impact force generated by the train during operation or shunting. As the running speed of the train continues to increase, the role of the coupler buffer device, which transmits the longitudinal traction force and compression force of the train and eases the longitudinal impulse of the train, is becoming more and more important. At present, the tight-fitting couplers used on domestic CRH-type EMUs are ma...
