Automatic rail lifting and sleeper replacing machine

Abstract

The invention discloses an automatic rail lifting and sleeper replacing machine. The automatic rail lifting and sleeper replacing machine is composed of a sleeper four nut synchronous mounting and dismounting device, a rail lifting device, a sleeper rotating, pushing and pulling device, a generator, a hydraulic system and control system box and a rail car. The rail car is provided with four trundles and two longitudinal beams. The sleeper four nut synchronous mounting and dismounting device, the rail lifting device, the sleeper rotating, pushing and pulling device, the generator and the hydraulic system and control system box are arranged on the two longitudinal beams of the rail car. The rail car is drawn by a shop truck. According to the automobile rail lifting and sleeper replacing machine, working devices can be automatically aligned to working positions; four nuts can be synchronously mounted and dismounted, pretightening force of the four nuts can be consistent, the fatigue life of bolts is prolonged, and reliability of connection between a sleeper and a rail is ensured; the machine can adapt to related work of sleeper replacing on linear rail sections and curved rail sections; and the sleeper rotating, pushing and pulling device is an integrated device, and the machine is simple and compact in structure, capable of achieving automatic control, convenient to operate and high in sleeper replacing working efficiency.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to an automatic rail lifting and sleeper changing machine. Background technique [0002] During the long-term use of railway sleepers, due to natural settlement and vibration, the railway track bed partially settles and needs to be maintained. Individual sleepers are damaged and need to be replaced in time. In the process of track bed maintenance or sleeper replacement, manual work is used , time-consuming and labor-intensive, low work efficiency. The work cannot be completed within the effective train passage gap (commonly known as: skylight). Only by using small and efficient automatic machinery can the train passage gap be used for unsealed road operations. Contents of the invention [0003] The purpose of the present invention is to provide an automatic rail lifting and sleeper changing machine. [0004] The present invention is composed of four nut synchronous assembly and d...
