Automatic sleeper replacing device

Abstract

The invention discloses an automatic sleeper replacing device which is composed of a sleeper four-nut synchronous assembling and disassembling device, a rail lifting device, a sleeper-rotating and sleeper pushing-and-pulling device, a generator, a hydraulic system and control system cabinet and a rail car. The rail car is provided with four trundles and two longitudinal beams. The sleeper four-nut synchronous assembling and disassembling device, the rail lifting device, the sleeper-rotating and sleeper pushing-and-pulling device, the generator and the hydraulic system and control system cabinet are arranged on the two longitudinal beams of the rail car. The rail car is dragged by an engineering truck. According to the automatic sleeper replacing device, the working devices can be aligned with working positions automatically, four-nut synchronous assembling and disassembling can be achieved, pretightening force of four nuts is made consistent, the fatigue lives of bolts are prolonged, and connection reliability of sleepers and steel rails is guaranteed; the automatic sleeper replacing device can adapt to relevant operations for sleeper replacing of linear and curved railway sections; and the sleeper-rotating and sleeper pushing-and-pulling device is an integrated device, is simple and compact in structure, convenient to operate and high in sleeper replacing efficiency, and automatic control is achieved.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to an automatic sleeper replacement device. 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 object of the present invention is to provide an automatic sleeper replacement device. [0004] The present invention is composed of four nut synchronous assembly and disassembly devices for sleepers...
