Intelligent maintenance system and method for track fasteners of track maintenance division

Abstract

The invention discloses an intelligent maintenance system and method for track fasteners of a track maintenance division. The intelligent maintenance system comprises a track car (1) running along a track, a tightening machine bearing vehicle (13) and a vehicle-mounted workstation (15). The tightening machine bearing vehicle (13) is connected with the track car (1) in a hanging manner, an intelligent tightening mechanism and an automatic nail feeding mechanism (6) are arranged on the tightening machine bearing vehicle (13), a fastener and track detection sensor (12) is arranged at one end of the intelligent tightening mechanism, the intelligent tightening mechanism comprises a tightening shaft controller (8), a tightening shaft control motor (9) in communication connection with the tightening shaft controller (8) and a servo fastener tightening shaft (5) connected with the tightening shaft control motor (9), and the vehicle-mounted workstation (15) is arranged in the track car (1). According to the system, a vehicle-mounted manual driving operation mode is adopted, a track flaw detection and track fastener locking torque sensor is installed on the track car, the image recognition technology is adopted in a combined manner, automatic detection of the track flaw detection and track fastener state and the bolt locking torque is achieved, and the working efficiency and the operation precision are improved.

Description

technical field [0001] The invention belongs to the technical field of rail transit maintenance equipment, and more specifically relates to an intelligent maintenance system and method for track fasteners in public works sections, which are mainly used for state detection and maintenance of rail line fasteners in public works sections such as high-speed railways and subways except for magnetic levitation Replacement and sleeper bolt assembly and tightening operations. Background technique [0002] With the high-speed and heavy-duty development of railway transportation, the safety monitoring of railways has also reached a new height. As an important part of the railway track system, fasteners will bear multiple reciprocating and periodic transverse and longitudinal bending stresses during service, which will inevitably cause damage such as breakage and loss. When fasteners When there are three or more damages in a row, the train will have a high probability of derailment. ...

AI Technical Summary

Problems solved by technology

The heavy-duty fuel-powered power wrench has sustainable power and can be assembled to a rail trolley; but it is only suitable for vertical rail bolt conditions, and cannot adapt to fishplate conditions. The machine is heavy, noisy, has exhaust emissions, and has no data collection, storage and transfer function
