Abstract

The invention discloses a sleeper replacement machine with a parallel four-bar mechanism. The sleeper replacement machine is composed of a tamping and ballast leveling device, a rail shoulder and rail bed modification device, a grab bucket stone-removal device, a ballast concentrated discharging device, a sleeper end stone-removal device, a chain gear stone discharging device, a four-nut synchronous assembly and disassembly device, a rail lifting device, a rail switching and sleeper sliding device, a sleeper hoisting device, an electric generator, a hydraulic system and control system cabinet and a rail vehicle. The sleeper replacement machine can quickly make a working device be aligned with the working position, automatically discharge ballast between sleepers, on the outer side of the sleeper ends and on a rail bed below steel rails, automatically separate sandy soil from the ballast, automatically make the ballast backfill the portion between new sleepers on the two sides and be tamped and leveled, and automatically modify the shape of a rail shoulder and the rail bed; four nuts are assembled and disassembled synchronously, the fatigue life of bolts is prolonged, and connection reliability of the sleepers and the steel rails is ensured; and the rail switching and sleeper sliding device is an integrated device, and is compact in structure and suitable for various operations for sleeper replacement of linear and curved rail sections, and efficiency of sleeper replacement work is high.

Description

technical field

[0001] The invention relates to a railway maintenance machine, in particular to a sleeper replacement machine with a 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 to be maintained. Individual sleepers are damaged and need to be replaced in time. Time-consuming and labor-intensive, 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 sleeper replacement machine with a 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 pillow end stone cleaning device, a sprocket stone discharge device,...
