Robot-based intelligent track fastener inspection and maintenance system and maintenance method

The invention discloses an intelligent track fastener inspection and maintenance system and method based on a robot. Fastener inspection and maintenance are one of daily key work of railway engineering departments. The system comprises a self-walking platform, a positioning detection system module, a control system module, a tightness subsystem module, a rust removal and oil coating subsystem module, a safety protection system and an embedded data processing system. A laser radar positioning technology, a laser ranging technology and a machine vision image recognition technology are combined and utilized, a motion control technology is utilized, intelligent screwing or unscrewing of a fastener bolt which is automatically inspected to be loosened is achieved, and rust removal, oil coating and drying work is conducted on a fastener part which is automatically inspected to be unqualified in surface state; and full automation and intelligentization of track fastener state detection and maintenance are realized. 本
