Sleeper replacing machine with swinging first rail lifting device

Abstract

The invention discloses a sleeper replacing machine with a swinging first rail lifting device. The sleeper replacing machine consists of a four-nut synchronous assembling and disassembling device, a first rail lifting device, a sleeper rotating, pushing and pulling device, a sleeper hoisting device, an electricity generator, a hydraulic system, a control system box and a railcar, wherein a plurality of casters and two stringers are arranged on the railcar; the four-nut synchronous assembling and disassembling device, the first rail lifting device, the sleeper rotating, pushing and pulling device, the sleeper hoisting device, the electricity generator, the hydraulic system and the control system box are arranged on the two stringers of the railcar; and the railcar is drawn by a rider-type truck. Through the adoption of the sleeper replacing machine disclosed by the invention, working devices can be quickly aligned to corresponding working positions; the purpose that four nuts are synchronously assembled and disassembled is realized, so that the pretightening forces of the four nuts are consistent, the fatigue life of bolts is prolonged, and the reliability of the connection between a sleeper and steel rails is guaranteed; the work of hoisting and placing the sleeper is quick; the sleeper replacing machine is adapted to the work of sleep replacement in a straight line railway section and a curved line railway section; the sleeper rotating, pushing and pulling device is an integrated device, so that the sleeper replacing machine disclosed by the invention is simple and compact in structure, automatically controlled, convenient to operate, and high in working efficiency of sleeper replacement.

Description

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