Disassembling device for car coupler buffer

Abstract

The invention provides a disassembling device for a car coupler buffer, wherein the car coupler buffer is positioned in a locomotive drag buffering device. The disassembling device comprises a screw rod, wherein the screw rod is provided with a head which is in contact with a front auxiliary plate of the locomotive drag buffering device; the tail of the screw rod can be detachably connected with a rotary operation handle; a threaded section of the screw rod is screwed with a nut plate; and the nut plate can be accommodated between the front auxiliary plate of the locomotive drag buffering device and a coupler tail frame. By the disassembly device, the rotary operation handle is operated to extrude the front auxiliary plate by the screw rod so as to compress the buffer; in addition, supporting force opposite to tension force generated by compressing the buffer when the screw rod is screwed by the nut plate, so that the car coupler buffer can be quickly disassembled by the device; and the device has a simple structure, is convenient to operate and avoids the damage caused by the car coupler buffer.

Description

technical field [0001] The invention relates to a railway vehicle maintenance tool, in particular to a coupler buffer removal device. Background technique [0002] Locomotive traction buffer device is an important component of railway vehicles, its quality directly affects the safety and running quality of rolling stock. figure 1 It is a schematic diagram of the structure of the locomotive traction buffer device, such as figure 1 As shown, the specific composition and connection relationship of the locomotive traction buffer device 1 is as follows: the coupler 11 is connected to the coupler frame 15 by the coupler pin 12, the coupler buffer 14 is an elastic component, one end of which withstands the front slave plate 13, and the front The slave plate 13 bears against the front slave plate seat 17, and the other end of the coupler buffer 14 withstands the rear slave plate seat 18, thereby limiting the front and rear movement of the coupler frame 15, while the coupler frame s...

Problems solved by technology

[0004] However, these two dismounting methods all have defects. In the first scheme, the coupler buffer hydraulic compressor has a large volume, heavy weight, and inconvenient transportation, and is not suitable for the work needs of disassembling the coupler buffer 14 under temporary conditions; in the second scheme, use Relying on the coupler tail frame as a fulcrum, the crowbar forces the coupler buffer 14 to compress, and then removes the coupler buffer 14, which can only temporarily compress the coupler buffer 14. In the process of the downward movement of the coupler buffer 14, it needs to be repeated many times. Only by prying, the coupler buffer 14 can continue to move downward. The coupler buffer 14 has a relatively large elastic force, and it takes time and effort to operate. After being removed, the coupler buffer 14 becomes fully extended and cannot be restored.
