Sleeper replacing device with four-nut synchronous mounting and dismounting function

Abstract

The invention discloses a sleeper replacing device with a four-nut synchronous mounting and dismounting function. The sleeper replacing device with the four-nut synchronous mounting and dismounting function is composed of a sleeper four-nut synchronous mounting and dismounting device, a rail lifting device, a sleeper turning and sleeper pushing-pulling device, a power generator, a hydraulic system, a control system box and a rail car. The rail car is provided with four trundles and two longitudinal beams. The sleeper four-nut synchronous mounting and dismounting device, the rail lifting device, the sleeper turning and sleeper pushing-pulling device, the power generator, the hydraulic system and the control system box are arranged on the two longitudinal beams of the rail car. The rail car is pulled by an engineering truck. According to the sleeper replacing device with the four-nut synchronous mounting and dismounting function, a working device can be aligned to a working position automatically; synchronous mounting and dismounting of four nuts can be achieved, pretightening force of the four nuts is made consistent, the fatigue life of bolts is prolonged, and the connecting reliability of sleepers and a steel rail is ensured; the sleeper replacing device can adapt to relevant work of sleeper replacement of linear and curved rail sections; and sleeper turning and sleeper pushing-pulling are achieved through the integrated device, the structure is simple and compact, automatic control is achieved, operation is convenient, and the sleeper replacing efficiency is high.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to a sleeper replacement device with the function of synchronous assembly and disassembly of four nuts. Background technique [0002] During the long-term use of railway sleepers, due to natural settlement and vibration, the railway track bed partially settles and needs to be maintained. Individual sleepers are damaged and need to be replaced in time. In the process of track bed maintenance or sleeper replacement, manual work is used , time-consuming and labor-intensive, low work efficiency. The work cannot be completed within the effective train passage gap (commonly known as: skylight). Only by using small and efficient automatic machinery can the train passage gap be used for unsealed road operations. Contents of the invention [0003] The purpose of the present invention is to provide a sleeper replacement device with the function of synchronous assembly and disassembly of fou...
