Automatic sleeper replacement machine

Abstract

The invention discloses an automatic sleeper replacement machine which is composed of a sleeper four-nut synchronous mounting and demounting device, a rail lifting device, a sleeper rotating and push-pull device, a generator, a hydraulic system, a 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 demounting device, the rail lifting device, the sleeper rotating and push-pull device, the generator, the hydraulic system and the control system box are arranged on the two longitudinal beams of the rail car, and the rail car is pulled by a shop truck. According to the automatic sleeper replacement machine, the work devices can be automatically aligned to work positions; four nuts can be synchronously mounted and demounted, the four nuts are consistent in pretightening force, the fatigue life of bolts is prolonged, and the connecting reliability of a sleeper and a steel rail is ensured; the automatic sleeper replacement machine can adapt to relevant work of linear and curved rail section sleeper replacement; the sleeper rotating and push-pull device is an integrated device, the structure is simple and compact, automatic control is achieved, operation is convenient, and sleeper replacement work efficiency is high.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to an automatic machine for replacing sleepers. 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 machine for sleeper replacement. [0004] The present invention is composed of four nut synchronous assembly and disassembly devices fo...
