The application of laser processing technology in rail transit manufacturing, in addition to welding, cutting, surface modification of key parts, marking, drilling and micromachining, etc., laser cleaning has also become a popular application in rail transit manufacturing in recent years.
The railway tracks are laid in the open air, and affected by factors such as rain and sunlight, the surface is prone to rust (or fouling). When the rail surface and the inner rust layer are seriously dirty, it is easy to cause poor rail circuit shunting, affect the transmission of railway signals, and endanger driving safety. At present, there are mainly two methods of manual grinding and derusting and large-scale rail derusting and grinding machines to remove the rust layer and dirt on the 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 efficiency, easy to damage the rails, and difficult to guarantee the cleaning quality.
Large-scale rail derusting and grinding machine, the equipment has a large power and a large volume. It needs to have its own generator, which needs to be driven by the traction locomotive to run on the railway. It is necessary to submit a transportation plan before the operation. The occupation of the line during the on-site operation will affect the driving transportation, and the cost If it is too high, it will have a great impact on the environment around the rails.
Laser cleaning is a new technology 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 base material, no need to apply for a railway transportation plan, easy to drag with one hand or complete the operation automatically by remote control, these advantages are The existing cleaning method cannot be replaced, and its development prospect is greatly optimistic.
For more than 16 years, Suntop Laesr has been committed to providing high-quality laser machine products and continuously improving its technology and performance. Our handheld laser cleaning machines range from 1000W to 2000W, and are widely used in rail transportation, including wheel set cleaning, brake beam cleaning, rail cleaning, etc. If you are interested in our laser cleaning equipment or want to know more information, please contact us.
