Sleeper replacing device with sleeper four-nut synchronous assembly and disassembly device

Abstract

The invention discloses a sleeper replacing device with a sleeper four-nut synchronous assembly and disassembly device. The sleeper replacing device is composed of the four-nut synchronous assembly and disassembly device, a sleeper lifting device, a retracking and sleep pushing and pulling device, a sleeper hoisting device, a power generator, a hydraulic system, a control system box and a track car. The track car is provided with multiple trundles and two longitudinal beams, the four-nut synchronous assembly and disassembly device, the sleeper lifting device, the retracking and sleep pushing and pulling device, the sleeper hoisting device, the power generator, the hydraulic system and the control system box are arranged on the two longitudinal beams of the track car, and the track car is dragged by an engineering van. A working device can be rapidly aligned with a working position; four-nut synchronous assembly and disassembly are achieved, the pretightening force of four nuts is consistent, the fatigue life of bolts is prolonged, and the reliability of the sleeper and steel rail connection is guaranteed; sleepers are rapidly hoisted and placed; the sleeper replacing device adapts to linear and curved rail road segment sleeper replacing work; the retracking and sleep pushing and pulling device is an integrated device, the structure is simple and compact, automatic control is achieved, operation is convenient, and sleeper replacing work efficiency is high.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to a sleeper changing machine with a device for synchronously installing and disassembling four nuts of a sleeper. 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 sleeper changing machine with a device for synchronously installing and dismounting four nuts of the sleeper. [0004] The invention is composed of a four-nut synchronous assembly and disassembly device, a rail lifting device, a rai...
