Tie renewal machine with series parallel four-rod mechanism

Abstract

The invention discloses a tie renewal machine with a series parallel four-rod mechanism, 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 tie end destoning apparatus, a chain-tooth rock discharging apparatus, a four-nut synchronous handling apparatus, a first rail lifting apparatus, a tie transfer and sliding apparatus, a tie 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 between ties, outside of tie ends and the bed below a track, sandy soil in the rock ballast is automatically separated and is automatically applied back to fill the space between ties on two sides a renewed tie 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 tie and track connection reliability is guaranteed; the tie transfer and sliding apparatus is an integrated apparatus with compact structure, adapting to various tie renewing workers at linear and curved rail sections, and tie renewing efficiency is improved.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to a pillow changing machine with a series parallel four-bar mechanism. 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 pillow changing machine with a series parallel four-bar mechanism. [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 device, a pi...
