Sleeper four nut synchronization assembly and disassembly device

Abstract

The invention discloses a sleeper four nut synchronization assembly and disassembly device. The sleeper four nut synchronization assembly and disassembly device is composed of a four nut synchronization assembly and disassembly device, a rail car, an electric generator, a hydraulic system case, a camera component and a monitor, wherein four trundles and two longitudinal beams are installed on the rail car, the four nut synchronization assembly and disassembly device, the electric generator and the hydraulic system case are arranged on two longitudinal beams of the rail car, the rail car is dragged by an engineering truck, the monitor is arranged in a cab of a tractor truck, the electric generator provides power to an oil pump, and an oil tank, an oil pump and various hydraulic valves are installed in the hydraulic system case. The sleeper four nut synchronization assembly and disassembly device can adapt to sleeper nut assembly and disassembly work at straight and curve rail segments, can rapidly align four magnetic inner hexangular sockets to four bolts of a sleeper, saves time and is high in work efficiency due to the fact that four nuts are synchronously assembled and disassembled, conveniently achieves the purpose that pre-tightening force of the four nuts is consistent, improves fatigue life of the bolts, guarantees reliability of a connection between the sleeper and a steel rail, easily achieves program automatic control, and is convenient to operate.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to a four-nut synchronous assembly and disassembly device for a sleeper. Background technique [0002] During the long-term use of railway sleepers, due to natural settlement and vibration, individual sleepers are damaged and need to be replaced in time. In the process of sleeper replacement, first remove the nuts fixed to the four bolts of the damaged sleeper. After replacing the sleeper, install the four nuts on the replaced sleeper bolts. Manually turning a single nut is time-consuming and laborious, and the work efficiency is low. It is difficult to achieve the same pretightening force of the four nuts. Contents of the invention [0003] The object of the present invention is to provide a device for synchronous assembly and disassembly of four nuts of a sleeper. [0004] The invention is composed of a four-nut synchronous assembly and disassembly device, a rail car, a generato...
