Automatic laser cladding vehicle for rail transit

The invention provides an automatic laser cladding vehicle for rail transit. The automatic laser cladding vehicle comprises a cladding vehicle body, a water cooling machine, an air source and an external power source. Wherein the cladding vehicle is an automatic advancing trolley placed on a track, and the cladding vehicle carries out cladding on the track in the advancing process; the water cooling machine provides cooling circulating water for the cladding vehicle; and the external power supply supplies power to the water cooling machine and the cladding vehicle. According to the method, the advantages of laser cladding are utilized, a novel automatic cladding vehicle on the track is adopted for laser cladding of the track, the heat affected area is small, metallurgical bonding is achieved, the surface is smooth, and rapid and high-quality repairing of the track is achieved. 本发明提供了轨道交通用自动激光熔覆车，包括熔覆车、水冷机、气源、外部电源；其中熔覆车为放置在轨道上的自动行进小车，熔覆车在行进过程中对轨道进行熔覆；水冷机为熔覆车提供冷却循环水；外部电源为水冷机和熔覆车提供电源。本发明利用激光熔覆的优势，采用可以在轨道上自动新型的熔覆
