Mechanical-electrical-hydraulic integration sleeper replacement machine

Abstract

The invention discloses a mechanical-electrical-hydraulic integration sleeper replacement machine. The mechanical-electrical-hydraulic integration sleeper replacement machine is composed of a tamping ballast flattening device, a road shoulder and road bed shape repairing device, a grab bucket stone clearing device, a ballast concentrated discharging device, a sleeper end stone clearing device, a sprocket stone discharging device, a four-nut synchronous assembling and disassembling device, a first rail lifting device, a sleeper rotating, pushing and pulling device, a sleeper hoisting and conveying device, a generator, a hydraulic system and control system box and a rail vehicle. According to the mechanical-electrical-hydraulic integration sleeper replacement machine, a working device can be quickly aligned with a working position; ballast located between sleepers, on the outer sides of the ends of the sleepers and on a road bed under a steel rail is automatically discharged, sandy soil in the ballast is automatically separated, the ballast is automatically placed between sleepers on the two sides of replaced sleepers in a backfilling mode, and then tamped and flattened in a vibration mode, and the shape of a road shoulder and the shape of the road bed are automatically repaired; four nuts can be assembled and disassembled synchronously, the fatigue life of bolts is prolonged, and the connection reliability of the sleepers and the steel rail is ensured; and the sleeper rotating, pushing and pulling device is an integrated device, the structure is compact, the sleeper replacement machine adapts to various jobs of sleeper replacement of linear and curved rail sections, and the sleeper replacement working efficiency is high.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to an electromechanical-hydraulic integrated sleeper replacement machine. 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 electromechanical-hydraulic integrated sleeper replacement machine. [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,...
