Small railway maintenance machine provided with sleeper end ballast clearing device

Abstract

The invention discloses a small railway maintenance machine provided with a sleeper end ballast clearing device. The small railway maintenance machine provided with the sleeper end ballast clearing device is composed of a tamping ballasting device, a runway shoulder and ballast bed shape repairing device, a clam bucket ballast clearing device, a ballast collecting and discharging device, the sleeper end ballast clearing device, a sprocket ballast discharging device, a four nut synchronous assembly and disassembly device, a first track lifting device, a retracking and sleeper push-pull device, a sleeper hoisting and swinging device, a rail car, a generator and a hydraulic system and control system box. According to the invention, the working devices can be aligned with the working positions quickly; ballast between sleepers, on the outer sides of sleeper ends and on a ballast bed below the rail is automatically discharged; sandy soil in the ballast is automatically separated, the ballast is automatically backfilled between sleepers on the both sides of the already-exchanged sleeper to be tamped and vibrated, and the shapes of the runway shoulder and the ballast bed are automatically repaired; four nuts are assembled and disassembled synchronously, the fatigue life of bolts is prolonged, and the connection reliability of the sleepers and the rail is guaranteed; and the retracking and sleeper push-pull device is an integrated device, the structure is compact, various tasks of sleeper exchanging at straight and curved rail sections are adapted to, and the working efficiency of sleeper exchanging is high.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to a small railway maintenance machine with a stone cleaning device at the pillow end. 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 stone cleaning device at the pillow end. [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 collect...
