[0027] The improvement in this embodiment is as follows:

[0028] High-pressure water jet technology is used to remove paint from the wheelset surface. This avoids wear on the wheelset surface during paint removal, eliminates the consumables used in traditional paint removal operations, reduces environmental pollution, and eliminates health hazards for operators.

[0029] The wheelset drive device 2 drives the wheelset to rotate along the axis, and the two high-pressure rotary nozzles 42 move laterally from both sides of the wheelset to remove paint from the wheelset at the same time, which improves the efficiency of wheelset paint removal.

[0030] Based on the above, other structures also need to be disclosed in detail, such as:

[0031] To drive the wheelset rotation and enable the device to remove paint from different parts of the wheelset, the wheelset drive device 2 includes a wheelset shift fork device 21 and a wheelset ejection device 22.

The wheelset ejection device 22 and the wheelset buffer device 23 are located on the left and right sides of the wheelset drive device 2. The outer side of the wheelset ejection device 22 contacts the surface of the wheelset. The wheelset drive device 2 includes a wheelset drive shaft 24, with outer sides of the wheelset drive shaft 24 at both ends. The wheelset is connected to the wheel set surface by a transmission connection.

The wheelset drive shaft 24 is driven to rotate by the wheelset drive transmission device 25. The wheelset drive shaft 24 transmits power to the wheelset, causing the wheelset to rotate around the axis. This facilitates the painting work at different positions of the wheelset and effectively improves the painting effect.

The wheelset shift fork device 21 and wheelset buffer device 23 in the wheelset drive unit 2 push the wheelset and slowly drop it into the wheelset drive shaft 24. The wheelset drive transmission device 25 drives the wheelset drive shaft 24 to rotate, and the wheelset drive shaft 24 transmits power to the wheelset, causing the wheelset to rotate along the axis. Next, the wheel set model and parameters are determined by the wheel set detection device 3. The X-axis drive device 43 in the wheel set contour paint removal device 4 drives the Z-axis module device 44 to move laterally on one side of the X-axis module device 41, thereby adjusting the X-axis position of the high-pressure rotary nozzle 42 and the Z-axis module device 44.
