Mechanical-electrical-hydraulic integrated rapid sleeper changing device

Abstract

The invention discloses a mechanical-electrical-hydraulic integrated rapid sleeper changing device. The mechanical-electrical-hydraulic integrated rapid sleeper changing device comprises a tamping and ballast leveling device, a runway shoulder and ballast bed profile modification device, a grab bucket stone clearing device, a stone ballast collection and discharge device, a sleeper end stone clearing device, a sprocket stone discharge device, a four-nut synchronous assembling and disassembling device, a first rail lifting device, a sleeper transferring and push-pull device, a sleeper hoisting device, a generator, a hydraulic system and control system box and a rail car. By means of the machine, work devices can be rapidly aligned in the work positions; stone ballast between sleepers, on the outer side of the sleeper end and on a ballast bed below a steel rail is automatically discharged, sandy soil in the stone ballast is automatically separated, a space between the sleepers which have been changed on two sides is automatically backfilled with the stone ballast, the stone ballast is tamped and leveled, and the shapes of a runway shoulder and the ballast bed are automatically repaired; four nuts are synchronously assembled and disassembled, the fatigue life of bolts is prolonged, and the reliability of connection of the sleepers and the steel rail is guaranteed; the sleeper transferring and push-pull device is an integrated device, is compact in structure and adapts to various works for sleeper changing in straight-line and curved rail sections, and the sleeper changing work efficiency is high.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to an electromechanical-hydraulic integrated fast pillow changing device. 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. In the process of sleeper replacement, artificial ballast is used , 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 an electromechanical-hydraulic integrated fast pillow changing device. [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...
