Railway maintenance electro-hydraulic integration machine for replacing sleeper

Abstract

The invention discloses a railway maintenance electro-hydraulic integration machine for replacing sleeper. The railway maintenance electro-hydraulic integration machine for replacing sleeper comprises a tamping ballast leveling device, a runway shoulder and ballast bed trimming device, a grab bucket stone-cleaning device, a ballast discharge device, a sleeper end stone-cleaning device, a sprocket stone discharge device, a four-nuts synchronous installation and disassembly device, a first rail lifting device, a sleeper transfer and push-pull device, a hoisting and swinging sleeper device, a rail vehicle, generators, a hydraulic system and a control system box. The railway maintenance electro-hydraulic integration machine for replacing sleeper makes a work device quickly aligned to a work position, the ballasts are automatically discharged from the gap between sleepers, the outside of a sleeper end and the ballast bed below a steel rail; sandy soils in the ballast are automatically separated, the ballast are automatically used to backfill the gap between the sleepers at two sides of the replaced sleeper for tamping and leveling, the shape of runway shoulder and ballast bed are repaired, the synchronous installation and disassembly of four nuts are achieved, the fatigue life of the bolt is improved, and the reliability of the connection between the sleeper and he steel rail are ensured. The sleeper transfer and push-pull device is an integrated device, has compact structure, and is suitable for various works of the sleeper changing in straight-line and curve-line rail sections. The efficiency of the sleeper changing is high.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to a railway maintenance electro-hydraulic integrated machine for replacing sleepers. 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 a kind of railway maintenance electro-hydraulic integrated machine for replacing sleepers. [0004] The present invention consists of a tamping ballast leveling device, a road shoulder and ballast bed modification device, a grab stone cleaning device, a ballast ...
