Abstract

The invention discloses a mechanical-electrical-hydraulic integrated sleeper replacement device. The mechanical-electrical-hydraulic integrated sleeper replacement device is composed of a four-nut synchronous assembly and disassembly device, a rail lifting device, a rail switching and sleeper sliding device, a sleeper hoisting device, an electric generator, a hydraulic system and control system cabinet and a rail vehicle, wherein the rail vehicle is provided with a plurality of trundles and two longitudinal beams; the four-nut synchronous assembly and disassembly device, the rail lifting device, the rail switching and sleeper sliding device, the sleeper hoisting device, the electric generator and the hydraulic system and control system cabinet are arranged on the two longitudinal beams of the rail vehicle; and the rail vehicle is dragged by an engineering vehicle. By means of the mechanical-electrical-hydraulic integrated sleeper replacement device, a working device can be aligned at the working position quickly; four nuts are assembled and disassembled synchronously, so that the pretightening forces of the four nuts are coincident, the fatigue life of bolts is prolonged, and connection reliability of a sleeper and a steel rail is ensured; the sleeper is quickly hoisted and arranged; the device is suitable for sleeper replacement of linear and curved rail sections; and the rail switching and sleeper sliding device is an integrated device, the structure is simple and compact, automatic control is achieved, operation is convenient, and efficiency of sleeper replacement work is high.

Description

technical field

[0001] The invention relates to a railway maintenance machine, in particular to an electromechanical-hydraulic integrated replacement sleeper 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 purpose of the present invention is to provide an electromechanical-hydraulic integrated sleeper replacement device.

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