Railway maintenance small-sized machine with shoulder shaping apparatus

Abstract

The invention discloses a railway maintenance small-sized machine with a shoulder shaping apparatus, comprising a tamping and ballast leveling apparatus, a ballast shoulder and bed shaping apparatus, a grab destoning apparatus, a rock ballast collecting and discharging apparatus, a sleeper end destoning apparatus, a chain-tooth rock discharging apparatus, a four-nut synchronous handling apparatus, a rail lifting apparatus, a sleeper transfer and sliding apparatus, a sleeper hoisting apparatus, a power generator, a hydraulic system and control system case and a track car. Working apparatuses can be aligned to working positions accurately; rock ballast is automatically discharged from the space between sleepers, ballast beds on the outside of sleeper ends and the ballast beds below tracks, sandy soil in the rock ballast is automatically separated and is automatically applied back to fill the space between sleepers on two sides of a renewed sleeper before being tamped, the shape of the ballast shoulder and bed is automatically restored; four nuts are handled in sync, fatigue life of a bolt is prolonged, and sleeper and track connection reliability is guaranteed; the sleeper transfer and sliding apparatus is an integrated apparatus with compact structure, adapting to various sleeper renewing workers at linear and curved rail sections, and sleeper renewing efficiency is improved.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to a small railway maintenance machine with a road shoulder shaping device. 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 object of the present invention is to provide a small railway maintenance machine with a road shoulder modification device. [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 collection and discharge...
