Railway rail surface laser-cladding rust-proof conducting method and apparatus for implementing method

Abstract

The invention relates to a railway rail surface laser-cladding rust-proof conducting method and an apparatus for implementing the method. The method is implemented by: subjecting rail surface to irradiation rust removal along a set path by laser; controlling a laser spot and a metal powder feeder to move synchronously along the rust removal path of step I, and controlling the metal powder feeder to apply metal powder evenly to the rust removal path on the rail surface; irradiating the metal powder with the laser spot to form a rust-proof conducting metal wire on the surface of the rail surface. The apparatus comprises a vehicle body, and a laser unit, a metal powder feeder and an electrical control unit which are arranged on the vehicle body. Rail surface rust removal is performed by means of laser washing; compared with mechanical or chemical rust removal methods, the method of the invention is high in efficiency and convenience and free of pollution, and laser rust removal has little influence on the surface of a rail base.

Description

technical field [0001] The invention relates to a laser cladding anti-rust and conductive method for railway rail surface and equipment for realizing the method. Background technique [0002] In order to check the state of the rail line occupied by the train, it is necessary to use a closed-circuit track circuit, through which the automatic signal judges the real-time state of the rail. When the train arrives above the rails in this area, a loop is formed between the two rails, and the section of the area is judged to be occupied by the signal light display. Otherwise, when there is no train above the rails, the circuit is broken between the two rails, and the signal feedback determines that the rails in this section are not occupied. Other trains are allowed to enter. Steel rails are an important part of closed-circuit track circuits. However, in practice, steel rails are laid in the open air and are affected by rain, sunlight, and temperature differences between day and n...
