The application of laser processing technology in rail transit manufacturing, in addition to welding, cutting, surface modification of key parts, marking, drilling and micro-processing, etc., laser cleaning has also become a popular application in rail transit manufacturing in recent years.
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 grinding machines are mainly used to remove the rust layer and dirt of the railway rails in operation.
Manual grinding and derusting 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.
The large-scale rail derusting and grinding machine has large power and large volume. It needs its own generator and needs to be driven by the traction locomotive to run on the railway. Before the operation, a transportation plan needs to be submitted. The occupation of the line during 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.
Laser cleaning is a new technology that is different from the traditional cleaning process in the past. It has received more and more attention because of its green energy saving and environmental protection. It has a very important application prospect in the rail transit industry. 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 its development prospects are greatly optimistic. Shanghai Shengtong Intelligent Laser Equipment Group is a laser cleaning manufacturer that has been in business for more than 10 years. Over the years, it has cooperated with the Chinese Academy of Sciences and scientific research institutions to develop, produce and sell laser cleaning equipment. Laser cleaning machines range from 50 watts to kilowatts. It has a wide range of applications, including wheelset cleaning, brake beam cleaning, rail cleaning, and more.
