Wheelset vertical disassembly machine

Abstract

The present invention relates to the field of equipment machinery for railway passenger and freight cars and subway vehicles, in particular to a wheel set vertical decomposition machine, which includes a grasping and lifting rotating main machine and two unloading machines, and the two unloading machines are separately arranged in the Grab and lift the two sides of the rotating main machine. The grabbing and lifting rotating main machine includes a grabbing device, a lifting mechanism and a turning device. The grabbing device is installed on the lifting mechanism and driven to lift by the lifting mechanism. The lifting The mechanism is installed on the slewing device and is driven to rotate horizontally by the slewing device. The wheel pair is grabbed by the grabbing device, and when disassembled, the wheel pair is driven to rotate to either side and vertically Place it upright on the unloader on that side. The invention changes the disassembly method of the wheel set from horizontal to vertical, and the wheels will automatically fall and separate by their own gravity, and the press machine that cannot be completely separated can be restarted and unloaded, which greatly improves the decomposition efficiency and does not cause wheel axle defects.

Description

technical field [0001] The invention relates to the field of equipment machinery for railway passenger and freight cars and subway vehicles, in particular to a wheel set vertical disassembly machine. Background technique [0002] For the wheel pairs of railway passenger and freight cars and subway vehicles, interference fit is adopted between the wheel pairs, brake discs, large gears, etc. and the axles. In order to facilitate disassembly, usually An oil injection hole is designed to inject high-pressure oil into the hub hole through the oil injection hole to expand the hub to reduce the unloading force. In the prior art, the domestic and foreign wheelset disassembly adopts the horizontal disassembly (horizontal) method. When the high-pressure oil is injected in this method, it is difficult to control the time of filling the high-pressure oil. The timing of the force is not easy to control, which can easily lead to excessive unloading force, which will lead to defects such ...

Problems solved by technology

In the prior art, the domestic and foreign wheelset disassembly adopts the horizontal disassembly (horizontal) method. When the high-pressure oil is injected in this method, it is difficult to control the time of filling the high-pressure oil. The timing of the force is not easy to control, and it is easy to cause excessive withdrawal force, which will cause defects such as straining the axle mating surface, resulting in the axle being scrapped, and the horizontal decomposition efficiency is also low
