The urban rail transit system is an important part of the city's "new infrastructure building", and it is also a key link in the formation of smart cities in the future. Environmental protection and digitalization will be the main development trends of smart cities. Rail transit cleaning operations have also become an indispensable key link in daily maintenance. Laser cleaning plays a pivotal role in the field of rail transit maintenance.
Due to the fact that railway tracks are laid in an open-air environment, affected by factors such as rain and sunlight, the surface is prone to rust (or fouling), and when the rust layer on the rail surface and inside is serious, it is easy to cause poor rail circuit shunting, affect the transmission of railway signals, and endanger traffic safety. At present, most of the railway track maintenance uses manual grinding and large-scale rail rust removal and grinding machines, which are labor-intensive, difficult to operate, expensive, and low in work efficiency. It has a great impact on the surrounding environment of the railway track, and it is easy to damage the railway substrate. Before operation, a transportation plan needs to be submitted. The occupation of the line during on-site operation affects traffic transportation, and it is difficult to guarantee the quality of rust layer and dirt cleaning on the rails in operation.
Laser cleaning is a new type of cleaning method. Laser cleaning technology is a cleaning solution using high-frequency short-pulse laser as the working medium. The specific wavelength of high-energy beam of light is absorbed by the rust layer, paint layer, and pollution layer, forming a rapidly expanding plasma, and at the same time generating shock waves. The shock wave turns the pollutants into fragments and is removed. The substrate will not absorb energy, will not damage the surface of the object to be cleaned, and will not reduce the surface finish. The laser cleaning equipment can work alone or with the robot arm cleaning operation. The cleaning cost is low, environmentally friendly, and efficient. The cleaning effect is good, and it does not hurt the rail substrate. It gradually replaces the traditional cleaning method and can be widely used in rail transit and other fields. Rust layer dirt cleaning, its development prospect is great.
