Mechanical-electrical-hydraulic integrated multifunctional railway maintenance machine

Abstract

The invention discloses a mechanical-electrical-hydraulic integrated multifunctional railway maintenance machine. The mechanical-electrical-hydraulic integrated multifunctional railway maintenance machine is composed of a tamping and ballast leveling device, a runway shoulder and ballast bed modification device, a grabbing bucket ballast cleaning device, a ballast collection and removal device, a sleeper end ballast cleaning device, a sprocket ballast discharging device, a four-nut synchronous assembling and disassembling device, a first rail lifting device, a shunting and push-pull sleeper device, a sleeper hoisting device, a power generator, a hydraulic system and control system box and a railcar. According to the mechanical-electrical-hydraulic integrated multifunctional railway maintenance machine, a working device can be rapidly aligned to a working position; ballast aggregates between sleepers, ballast aggregates of ballast beds at an outer side of a sleeper end and under steel rails are automatically discharged, and sandy soil in the ballast aggregates is automatically separated; the ballast aggregates are automatically backfilled between the sleepers at two sides of a changed sleeper and are tamped and flatly vibrated, and shapes of a runway shoulder and the ballast bed are automatically repaired; synchronous assembling and disassembling of four nuts are realized, and the fatigue life of a bolt is prolonged; the reliability of connecting the sleepers and the steel rails is guaranteed; a crossing sleeper and a push-pull sleeper are of an integrated device; the mechanical-electrical-hydraulic integrated multifunctional railway maintenance machine has a compact structure and is suitable for all work of changing the sleepers of straight-line and curve rail road sections, and the efficiency of sleeper changing work is high.

Description

Technical field [0001] The invention relates to a railway maintenance machine, in particular to a multifunctional railway maintenance machine with electro-hydraulic integration. Background technique [0002] In the course of long-term use of railway sleepers, due to natural settlement and vibration, local railway sleepers need to be maintained, and individual sleepers are damaged and need to be replaced in time. In the process of sleeper replacement, manual operations are used, which is time-consuming and labor-intensive , The work efficiency is low, and the work cannot be completed within the effective train passing gap (commonly known as: skylight). Summary of the invention [0003] The purpose of the present invention is to provide a multifunctional mechanical and electrical integrated machine for railway maintenance. [0004] The invention consists of a tamping and leveling device, a road shoulder and track bed shaping device, a grab stone cleaning device, a ballast collecting ...

AI Technical Summary

Problems solved by technology

[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 within the effective train passage gap (commonly known as: skylight)
