Abstract

The invention discloses an automatic machine for sleeper replacement. The automatic machine consists of a sleeper four-screw nut synchronous mounting and dismounting device, a sleeper lifting device, a sleeper turning and pushing device, a power generator, a hydraulic system, a control system box and a track trolley, wherein the track trolley is provided with four foot wheels and two longitudinal beams; the sleeper four-screw nut synchronous mounting and dismounting device, the sleeper lifting device, the sleeper turning and pushing device, the power generator, the hydraulic system and the control system box are arranged on the two longitudinal beams of the track trolley; the track trolley is tracked by a mobile machinery shop. By adopting the automatic machine, a working device can be automatically aligned to a working position, synchronous mounting and dismounting of four screw nuts can be achieved, the pre-tightening force of the four screw nuts can be accordant, the fatigue service life of a bolt can be prolonged, and the connection reliability of the sleeper and a steel rail can be ensured; the automatic machine is applicable to related operation that sleepers on straight line or curved line rail sections are replaced; the sleeper turning and pushing device is an integrated device which is simple and compact in structure, automatic to control, convenient to operate and high in sleeper replacement working efficiency.

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...
