[0041] The principle of this utility model is:

[0042] When the utility model is in use, the wheelset 5 to be cleaned is placed in the feed section 2 and blocked by the feed stopping mechanism 6. When cleaning is required, the feed stopper 64 in the feed stopping mechanism 6 is controlled to be flush with the track 1. Due to the cleaning arrangement of the track 1, the wheelset 5 automatically moves to the cleaning section 3. After the current wheelset 5 rolls out of the feed section 2, the feed stopping mechanism 6 quickly moves to stop the next wheelset 5.

[0043] When the wheelset 5 enters the cleaning section 3, the wheelset 5 to be cleaned is stopped by the cleaning stopping mechanism 92. At this time, the lifting device 91 is actuated to lift the wheelset 5. During the process, the wheelset 5 is lifted into the dust cover 71. At the same time, the rotating wheel driving motor 9131 drives the rotating roller 9132 to rotate, thereby driving the wheelset 5 to rotate in the air. At this time, the wheelset 5 can be laser cleaned by the cleaning mechanism 93. The six-axis manipulator 932 and the laser cleaning head are involved in the cleaning process. Since they are existing mature technologies, they will not be described here. During the cleaning process, the smoke and dust generated are collected by the industrial dust collector 72 to ensure the working environment. The industrial dust collector 72 is existing and the structural principle will not be described here.

[0044] The cleaned wheelset 5 is lowered onto the track 1 via the lifting device 91 , and the cleaning stop mechanism 92 is released in advance, so that the cleaned wheelset 5 automatically rolls to the discharge section 4 , thereby completing the entire cleaning process.
