Mechanical-electrical-hydraulic integration sleeper replacement device

Abstract

The invention discloses a mechanical-electrical-hydraulic integration sleeper replacement device. The mechanical-electrical-hydraulic integration sleeper replacement device is composed of a sleeper four-nut synchronous assembling and disassembling device, a rail lifting device, a sleeper rotating, pushing and pulling device, a generator, a hydraulic system and control system box and a rail car. The rail car is provided with four casters and two longitudinal beams. The sleeper four-nut synchronous assembling and disassembling device, the rail lifting device, the sleeper rotating, pushing and pulling device, the generator, and the hydraulic system and control system box are arranged on the two longitudinal beams of the rail car. The rail car is driven by an engineering car. By means of the mechanical-electrical-hydraulic integration sleeper replacement device, a working device can be automatically aligned to a working position, and four nuts can be synchronously disassembled and assembled, so that the pretightening force of the four nuts is consistent, the fatigue life of bolts is prolonged, and the connection reliability of a sleeper and steel rails is ensured; the mechanical-electrical-hydraulic integration sleeper replacement device can adapt to related work of sleeper replacement of linear and curved rail sections; the sleeper rotating, pushing and pulling device is an integrated device; and the structure is simple and compact, control is automatic, operation is convenient, and the sleeper replacement work efficiency is high.

Description

technical field [0001] The invention relates to a railway maintenance machine, in particular to an electromechanical-hydraulic integrated 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 electromechanical-hydraulic integrated sleeper replacement device. [0004] The present invention is composed of four nut...
