Disassembling tool for bogie

Abstract

The invention discloses a disassembling tool for a bogie. The disassembling tool comprises two trays, a positioning connection rod is connected between the two trays, a jack is arranged on each tray, a supporting positioning block is arranged at the end of an ejection rod of each jack, each tray is provided with a plurality of inverted-L-shaped connection rods, each inverted L-shaped connection rod is connected with a wheel shaft in a sliding mode, one end of each wheel shaft is connected with wheels, a compression spring is arranged between each wheel and the corresponding tray, and each compression spring is longer than the vertical rod of each inverted-L-shaped connection rod. The disassembling tool has the advantages that the wheels are installed on the inverted-L-shaped connection rods, the compressing springs are installed, and accordingly the wheels can be automatically ascended and descended; when the disassembling tool does not work, the trays can be lifted off the ground due to the fact that the compression springs are longer than the vertical rods of the inverted-L-shaped connection rods, and the wheels can drive the trays to move; when the disassembling tool works, the compression springs are compressed under the weight of the bogie on the supporting positioning blocks, the trays fall on the ground and the wheels are locked.

Description

technical field [0001] The invention relates to the technical field of dismantling tooling, in particular to a bogie dismantling tooling. Background technique [0002] After the train has been running for a long time, the bogie needs to be overhauled. At present, some train bogie systems use asymmetrical swivel wall positioning node axle boxes. During maintenance, because there is no effective support at the pivot arm nodes of the axle box, Some springs on the axle box are easy to fall off, causing personal injury, and the current commonly used method of supporting the pivot arm node of the axle box is to use sleepers or a separate jack for support, but the movement of the device is not convenient enough, and it is also not conducive to professional maintenance. change. [0003] Aiming at the problem in the existing related art that when the bogie with an asymmetrical swivel wall type positioning node axle box is overhauled, the support device of the axle box pivot arm node...
