Sleeper replacing machine with sleeper end stone removing device

Abstract

The invention discloses a sleeper replacing machine with a sleeper end stone removing device. The sleeper replacing machine is composed of a ramming ballast leveling device, a runway shoulder and ballast bed shaping device, a grab bucket stone removing device, a ballast collecting and discharging device, the sleeper end stone removing device, a sprocket stone discharging device, a four-nut synchronous assembling and disassembling device, a first rail lifting device, a rail rotating and sleeper push-pull device, a sleeper hoisting device, an electric generator, a hydraulic system and control system box and a rail car. According to the sleeper replacing machine, working devices can be quickly aligned to working positions; ballast between sleepers, on the outer sides of the sleeper ends and a ballast bed below a steel rail can be automatically discharged, sandy soil in the ballast can be automatically separated, the ballast can be automatically put back to the parts between sleepers on the two sides of replaced sleepers, rammed and vibrated to be level, and the shape of a runway shoulder and the ballast bed can be restored; four nuts can be synchronously assembled or disassembled, the fatigue life of bolts can be prolonged, and the reliability of connection between the sleepers and the steel rail can be ensured; the integrated rail rotating and sleeper push-pull device is adopted, and the sleeper replacing machine is compact in structure, suitable for various sleeper replacing work of linear and curve rail sections and high in sleeper replacing efficiency.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to a pillow changing 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 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 purpose of the present invention is to provide a pillow changing 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 collection and discharge device, a pillow end stone cleaning device, a sprocket stone ...
