Sleeper changing machine with opposite crank track lifting device

Abstract

The invention discloses a sleeper changing machine with an opposite crank track lifting device. The machine is composed of a tamping slag flattening device, a runway shoulder and track bed shaping device, a grab bucket stone removing device, a ballast collecting and discharging device, a sleeper end stone removing device, a sprocket stone discharging device, a four-nut synchronous assembling and disassembling device, a first track lifting device, a track transferring and sleeper pushing and pulling device, a sleeping lifting device, an electricity generator, a hydraulic system, a control system box and a track car. The working device can be rapidly aligned to the working position; ballast between sleepers, on the outer sides of the ends of the sleepers and the a ballast bed below a steel track are automatically discharged, sandy soil in ballast is automatically separated, the changed sleepers on the two sides are backfilled with the ballast automatically, tamping and vibrating flattening are performed, and the shapes of runway shoulders and ballast beds are automatically repaired; four-nut synchronous assembling and disassembling are achieved, the fatigue life of bolts is prolonged, and the connection reliability of the sleepers and the steel track is ensured; the sleeper transferring and sleeper pushing and pulling device is integrated, the structure is compact, the sleeper changing machine is suitable for various tasks of linear and curved track section sleeper changing, and the sleeper changing working efficiency is high.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to a pillow changing machine with an opposing crank rail lifting device. 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 pillow changing machine with an opposing crank rail lifting 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 device,...
