Railroad tracks are laid in the open air, and the surface is prone to rust (or fouling) due to factors such as rain and sunlight. When the rail surface and the inner rust layer are seriously dirty, it is easy to cause poor circuit shunting of the rail, which affects the transmission of railway signals and endangers the driving safety. At present, two methods of manual grinding and rust removal and large-scale rail rust removal and laser cleaning machine are mainly used to remove the rust layer and dirt of the railway rails in operation.
Manual grinding and rust removal is the main method of rail maintenance at present, but it is labor-intensive, difficult to operate, low in work efficiency, easy to damage the rail, and difficult to guarantee the cleaning quality.
Large-scale rail derusting and grinding machine, the equipment is large in power and large in size. It must have its own generator. It needs to be driven by the traction locomotive and run on the railway. Before the operation, it is necessary to submit a transportation plan. The occupation of the line during the on-site operation will affect the traffic transportation, and the cost If it is too high, it will have a greater impact on the surrounding environment of the railway track.
A new cleaning method developed in recent years during laser cleaning. Laser cleaning equipment is suitable for operators to work alone, with low cleaning cost, environmental protection, high efficiency, good cleaning quality, no damage to the rail substrate, no need to apply for a railway transportation plan, easy operation with one hand or automatic completion of the operation by remote control. These advantages are The existing cleaning methods cannot be replaced, and laser cleaning will gradually replace the traditional cleaning methods, and its development prospects will definitely replace the traditional cleaning processes.
