Sleeper changing machine provided with sleeper rotation and pushing-pulling integrated device

Abstract

The invention discloses a sleeper changing machine provided with a sleeper rotation and pushing-pulling integrated device. The sleeper changing machine is composed of a tamping and ballasting device, a rail shoulder and ballast bed correction device, a grab bucket stone removing device, a ballast collection and discharge device, a sleeper end stone removing device, a sprocket stone discharge device, a four-nut synchronous mounting and dismounting device, a first rail lifting device, the sleeper rotation and pushing-pulling device, a sleeper hoisting device, an electric generator, a hydraulic system and control system cabinet and a rail car. According to the sleeper changing machine, a work device can be quickly aligned with a work position; ballast, located between sleepers, outside sleeper ends and under steel rails, of a ballast bed is automatically discharged, sandy soil in the ballast is automatically separated, the ballast is automatically backfilled to the position between sleepers on the two sides of a changed sleeper, tamped and vibrated to be flat, and the shapes of a rail shoulder and the ballast bed are automatically restored; synchronous mounting and dismounting of four nuts are achieved, the fatigue lives of bolts are prolonged, and the connection reliability of the sleepers and the steel rails is ensured; and the sleeper rotation and pushing-pulling device is an integrated device and is compact in structure, suitable for various work of sleeper changing at linear and curve rail sections and high in sleeper changing efficiency.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to a sleeper changing machine with an integrated device for turning sleepers and push-pull 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 a sleeper changing machine with an integrated device for rotating sleepers and push-pull sleepers. [0004] The present invention consists of a tamping ballast leveling device, a road shoulder and ballast bed modification device, a grab stone clea...
