Railway sleeper replacing machine with device capable of synchronously assembling and disassembling four nuts of railway sleepers

Abstract

The invention discloses a railway sleeper replacing machine with a device capable of synchronously assembling and disassembling four nuts of railway sleepers. The railway sleeper replacing machine comprises a tamping and ballast leveling device, a ballast shoulder and ballast bed shaping device, a grabbing bucket ballast cleaning device, a ballast collecting and discharging device, a sleeper end ballast cleaning device, a chain tooth ballast discharging device, a four-nut synchronously assembling and disassembling device, a rail lifting device, a rail-turning and railway sleeper pushing-pulling device, a railway sleeper lifting and transporting device, a power generator, a hydraulic system and control system box, and a rail car. The railway sleeper replacing machine is capable of rapidly enabling operating devices to be aligned to operating positions, automatically discharging the ballast between the railway sleepers, the outer sides of the sleeper ends and the ballast beds under steel rails, automatically separating sand soil in the ballast, automatically backfilling the ballast till tamping and leveling the railway sleepers on two sides of the replaced railway sleepers, automatically repairing the shape of ballast shoulders and ballast beds, synchronously assembling and disassembling four nuts, prolonging the fatigue life of bolts and ensuring reliability of connection between the railway sleepers and the steel rails; the rail-turning and railway sleeper pushing-pulling device is an integrated device; the railway sleeper replacing machine is compact in structure, is adapted to various operations of replacing sleepers of straight and curved rail road sections, and is high in sleeper-replacing operation efficiency.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to a sleeper replacement machine with a four-nut synchronous assembly and disassembly device for the sleeper. 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 sleeper replacement machine with a device for synchronously installing and dismounting four nuts of the sleeper. [0004] The present invention consists of a tamping ballast leveling device, a road shoulder and ballast bed modification d...
