[0035] Based on the above-mentioned structural setting, the wheelset paint stripping protection device is composed of a driven shaft wheelset 100 and a first protection chassis 300, wherein the driven shaft wheelset 100 moves along a predetermined track for paint stripping treatment, and the first protection chassis 300 is set below the axle of the driven shaft wheelset 100 to receive the paint and paint stripping agent fallen off the axle of the driven shaft wheelset 100. Specifically, during the working process, the operator clamps the first protection chassis 300 on the bottom of the driven shaft wheelset 100 to be stripped, and rotates the first protection chassis 300 to remove the paint from the driven shaft wheelset 100. The first roller bearings 330 mounted on the outer ends of the two first shafts 320 on one side of the first waste box 310 are placed in contact with the inner side of the rim of one wheel of the driven shaft wheel pair 100, and the first roller bearings 330 respectively mounted on the outer ends of the two first shafts 320 on the other side of the first waste box 310 are placed in contact with the inner side of the rim of the other wheel of the driven shaft wheel pair 100, so that the first waste box 310 can be movably mounted under the driven shaft wheel pair 100, so that when the driven shaft wheel pair 100 rolls, the four first roller bearings 33 0 rotates accordingly, so that the first waste box 310 is always in a horizontal state, so as to collect the paint and paint stripping agent falling off the axle of the driven shaft wheelset 100.

For some specific machines or vehicles, such as in high-speed rail, the wheelset usually needs to be used in conjunction with a gearbox, which is an important transmission component connecting the traction motor and the axle. Figure 4 The driving shaft wheelset 200 in the vehicle and the gearbox mounted on the wheelset axle will affect the installation of the first protective chassis 300. Preferably, a second protective chassis 400 is designed, one side of which is placed on the inner side of the wheel rim of the driving shaft wheelset 200 through two second roller bearings 430, and the other side is clamped and fixed on the gearbox through a mounting clamp 440, so that the second protective chassis 400 can also roll with the rolling of the driving shaft wheelset 200 to achieve self-balancing.

[0037] Furthermore, the mounting clamp 440 includes a bracket 4410 welded to the second waste box 410, the bracket 4410 is continuously vertically bent and a clamp 4420 is welded to the outer side of the top surface thereof distributed along the horizontal plane, a first screw rod 4430 is threadedly penetrated on one side of the clamp 4420, the inner end of the first screw rod 4430 extends to the inner side of the clamp 4420 and a pressure plate 4440 is coaxially installed, and a gap for the gear box rib to be clamped is reserved between the pressure plate 4440 and the other side of the clamp 4420.

Specifically, the operator can rotate the second screw rod 540 outward or inward by turning the knob 550, and cooperate with the fixing rod 520 to achieve the position adjustment of the first shaft rod 320 or the second shaft rod 420. For example, when rotating outward, the outward extension of the first shaft rod 320 or the second shaft rod 420 can be extended, and when rotating inward, the outward extension of the first shaft rod 320 or the second shaft rod 420 can be shortened.

[0040] Furthermore, two weighted magnetic blocks 600 are respectively attracted to the bottom of the first waste box 310 and the second waste box 410. The first waste box 310 and the second waste box 410 respectively achieve self-balancing mainly by their own gravity with the help of the first roller bearing 330 and the second roller bearing 430.
