Problems solved by technology

[0002] During the long-term use of railway sleepers, due to natural settlement and vibration, the railway track bed partially subsides and needs to be maintained. Individual sleepers are damaged and need to be replaced in time. During the process of track bed maintenance or sleeper replacement, manual work is used , time-consuming and labor-intensive, low work efficiency

Abstract

The invention discloses a sleeper replacement device with a four-nut synchronous disassembly and assembly function. The sleeper replacement device is composed of a sleeper four-nut synchronous disassembly and assembly device body, a rail lifting device, a sleeper transferring, pushing and pulling device, a generator, a hydraulic system, a control system box and a rail car. The rail car is provided with four castors and two longitudinal beams. The sleeper four-nut synchronous disassembly and assembly device body, the rail lifting device, the sleeper transferring, pushing and pulling device, the generator and the hydraulic system are arranged on one of the two longitudinal beams of the rail car. The control system box is arranged on the other longitudinal beam of the rail car. The rail car is pulled by a construction vehicle. By the adoption of the sleeper replacement device with the four-nut synchronous disassembly and assembly function, the working device can be made to be aligned with the working position automatically; synchronous disassembly and assembly of four nuts can be achieved, the four nuts are the same in pretightening force, the fatigue life of bolts is prolonged, and the connecting reliability of a sleeper and a steel rail is guaranteed; the sleeper replacement device can adapt to the related operations of sleeper replacement of linear and curved rail sections; and the sleeper transferring, pushing and pulling device is an integrated device, and the sleeper replacement device is simple and compact in structure, automatic in control, convenient to operate and high in sleeper replacement efficiency.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to a pillow changing 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 pillow changing device with the function of synchronous assembly and disassembly of four nuts. ...
