Abstract

The invention discloses a three-dimensional digital laser repairing device of a steel rail. The device comprises a laser cladding robot system and a three-dimensional model rebuilding system, whereinthe robot system comprises an industrial personal computer, a robot, a robot controller, a laser generator, a laser welding gun, a metal powder conveyor and a spray head; the three-dimensional model rebuilding system comprises a laser scanning instrument and a video acquiring card; the video acquiring card is connected to the industrial personal computer; and the laser scanning instrument is connected to the video acquiring card. According to the three-dimensional digital laser repairing device and method of the steel rail, the steel rail can be automatically positioned, and a three-dimensional model of a broken part can be rebuilt, so that the robot moving route can be automatically planned and a laser switch can be automatically controlled through the three-dimensional model, and as a result, the broken part can be automatically repaired. With the adoption of the device and the method, the automation degree and the production capacity can be improved; and the processing accuracy andthe quality consistency can be improved.

Description

technical field [0001] The invention relates to the technical field of railway maintenance, in particular to a three-dimensional digital rail laser repair device and a repair method. Background technique [0002] Steel rails are the main components of railway tracks. Its function is to guide the wheels of the rolling stock to move forward, bear the huge pressure of the wheels, and transmit them to the sleepers. The rails must provide the wheels with a continuous, smooth and least drag rolling surface. In the electrified railway or automatic blocking section, the rail can also be used as a track circuit. [0003] With the rapid development of my country's railways, subways and other rail transit technologies, the increase in the axle load of locomotives and vehicles, and the increase in vehicle speed, higher requirements are placed on the quality of railway lines, and the treatment of rail surface diseases is imminent. [0004] The service life of railway and subway rails ...
