a method of a track laser cleaning system, as shown in fig. 3, comprising the steps of:
carrying out laser cleaning process experiments on different rust pollution degrees of the rail to obtain laser cleaning process parameters;
setting required cleaning process parameters, and transmitting a working signal to a driving system by a control system to enable the driving system to drive the moving platform to move along the track;
when the cleaning execution unit moves to a required cleaning area, the control system controls the trigger laser light source to emit laser, the laser beam is transmitted to the cleaning execution unit through the optical fiber, and the laser beam forms a required linear light spot after being shaped by the cleaning execution unit and acts on the surface of the track to be processed.
The method further comprises the following steps:
and the control system controls the cleaning execution unit to clean the first track and/or the second track, receives the corrosion and pollution information of the first track and the second track acquired by the detection system, and adjusts the cleaning time and/or the cleaning parameters of the cleaning execution unit at the corresponding positions of the first track and the second track.
The specific process of the track laser cleaning method provided by the invention is as follows: and carrying out laser cleaning process experiments on different rust pollution degrees of the rail in advance to obtain laser cleaning process parameters in different pollution states. The rail laser cleaning system starts a power supply of the whole system through a control interface, and sets required process parameters on the control interface according to the pollution degree of the rail in the area to be cleaned and the experimental data. And the dust removal system is started in advance until the cleaning is finished. The control system communicates with the driving system to give a working signal to the mobile platform, so that the roller starts to rotate. And the cooling system is started to provide cooling water for the laser light source and the water channel in the cleaning execution unit in advance. During the moving process of the moving platform, when the cleaning execution unit moves to the required cleaning area. The control system gives out a signal to trigger a laser in the laser light source to emit laser, a laser beam transmits the laser beam to the cleaning execution unit through an optical fiber, the laser beam forms a required linear light spot after being shaped by the cleaning execution unit, the linear light spot acts on the surface of the rail to be processed, and the size of the linear light spot is adjusted to a region suitable for rail cleaning by controlling the parameters of the galvanometer motor. When the designated area is processed, the control system gives a signal to prompt the laser to close the laser signal. Through the mode of settling the cleaning execution unit to the double track way, the laser beam is shaped into the required strip-shaped facula to act on the surface of the track, along with the movement of the mobile platform, the cleaning execution unit is driven to move along the track, thereby realizing the purpose of cleaning the track. By utilizing the laser cleaning mode, the laser can be transmitted by utilizing the optical fiber, so that the laser cleaning device has better elasticity in use and is easier to realize flexibility and automation. The track cleaning device has the advantages of simple structure, easiness in operation, high automation degree, good cleaning effect, capability of being cleaned in a single way, strong applicability, improvement on the service life of the track, reduction in the maintenance and replacement cost of the track traffic, good social effect and very wide application prospect in the field of track traffic.
