Automatic sleeper changing machine

Abstract

The invention discloses an automatic sleeper changing machine which is composed of a tamping and ballasting device, a runway shoulder and ballast bed shape correcting device, a grab bucket rock removing device, a ballast concentrated discharge device, a sleeper end rock removing device, a sprocket rock discharge device, a four-nut synchronous assembling and detaching device, a first rail lifting device, a retracking and sleeper push-pull device, a sleeper hoisting device, a power generator, a hydraulic system and control system box and a rail car. Working devices can be rapidly aligned with working positions; ballast between sleepers, on the outer sides of sleeper ends and on a ballast bed below steel rails is automatically discharged, sand and soil in the ballast are automatically separated, the ballast is automatically backfilled between the two sides of changed sleepers to be tamped and vibrated flat, and the shape of runway shoulders and ballast beds is automatically repaired; four nuts are synchronously detached and assembled, the fatigue life of bolts is prolonged, and the connection reliability of the sleepers and the steel rails is ensured; the retracking and sleeper push-pull device is an integrated device and is compact in structure, suitable for all work of linear and curved rail section sleeper changing and high in sleeper changing work efficiency.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to an automatic 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 an automatic 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 collection and discharge device, a pillow end stone cleaning device, a sprocket ston...
