Description

technical field

[0001] The invention relates to a railway maintenance machine, in particular to a pillow changing machine with a swing rail lifting device. Background technique

[0002] During the long-term use of railway sleepers, due to natural settlement and vibration, some railway sleepers sink and need maintenance. Individual sleepers are damaged and need to be replaced in time. In the process of sleeper replacement, manual work is used, which is time-consuming and laborious. , the work efficiency is low, and the work cannot be completed in the effective train passage gap (commonly known as: skylight). Contents of the invention

[0003] The object of the present invention is to provide a pillow changing machine with a swing rail lifting device.

[0004] The present invention is composed of a four-nut synchronous assembly and disassembly device, a first rail lifting device, a rail transition and push-pull sleeper device, a sleeper lifting device, a generator, a hydrau...
