Abstract

A dismantling mechanism and the separation tooling of the bogie and the body of the subway car, the bogie and the body of the separation tool include a dismantling platform, which is used to position the wheels through the wheel positioning plate and the wheel positioning groove; and drive the side mechanism to lift, And take the bottom surface of the vehicle body as a reference to position the side mechanism in the vertical direction; the side mechanism is used to disassemble the safety bolt and the height bolt respectively through the first disassembly mechanism and the second disassembly mechanism; the center mechanism is used to disassemble through the third disassembly mechanism The central bolt is powered by an oil cylinder; the dismantling mechanism is used to be respectively set on the big end of the safety bolt, the height bolt, and the central bolt, and is pre-clamped with the dismantling steel needle; the dismantling mechanism includes the first dismantling mechanism, the second The second disassembly mechanism and the third disassembly mechanism, the first disassembly mechanism, the second disassembly mechanism and the third disassembly mechanism have the same structure. The invention can quickly disassemble the center bolt, the height bolt and the safety bolt through the disassembly mechanism.

Description

technical field [0001] The invention relates to the maintenance technology of a subway car, in particular to a separation tool for a bogie and a body of a subway car. Background technique [0002] In the process of overhauling subway cars, it is necessary to separate the bogie from the body. At present, the bogie and the body are mainly connected by a center pin, a safety cable, and a height adjustment rod. The steel cable is assembled and fixed with the safety mounting plate on the vehicle body through the safety bolt, and the height adjustment rod is assembled and fixed with the height mounting bracket on the vehicle body through the height bolt. And generally the height bolt is assembled with the height nut after passing through the height mounting ring and the height mounting frame on the height adjustment rod. [0003] When dismantling the safety cable, simply unscrew the safety bolt out of the safety installation ring. When disassembling the height adjustment rod, it...
