Sleeper changing machine having swing rail-lifting device

Abstract

The invention discloses a sleeper changing machine having a swing rail-lifting device. The sleeper changing machine consists of a synchronous four-nut mounting-dismounting device, a rail-lifting device, a sleeper turning, pushing and pulling device, a sleeper hoisting device, a generator, a hydraulic system, a control system box and a rail car. The rail car is provided with multiple trundles and two longitudinal beams, the synchronous four-nut mounting-dismounting device, the rail-lifting device, the sleeper turning, pushing and pulling device, the sleeper hoisting device, the generator, the hydraulic system and the control system box are arranged on the two longitudinal beams of the rail car, and the rail car is dragged by an engineering vehicle. The device can rapidly align a working device to a working position, achieves synchronous four-nut mounting and dismounting and makes four nuts consistent in pre-tightening force, prolongs the service life of bolts, ensures the sleeper and steel rail connecting reliability, performs rapid sleeper hoisting and placement works, is suitable for linear and curved railway section sleeper changing work, is simple and compact in structure, convenient to operate and high in sleeper changing work efficiency and is automatically controlled, and the sleeper turning, pushing and pulling device is an integrated device.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to a pillow changing machine with a swing 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 a swing rail lifting device. [0004] The present invention is composed of a four-nut synchronous assembly and disassembly device, a first rail lifting device, a rail transition and push-pull sleeper device, a sleeper lifting device, a generator, a hydrau...
