[0034] As shown in the attached Figure 1 -attached Figure 3 The wheel wear detection device 300 comprises a frame 310 connected to the track, the frame 310 comprising a top plate 311 located above the track, the top plate 311 being provided with a side plate 312 on each side thereof in a vertical manner, and each side plate 312 being provided with a connecting plate 313 located inside the side plate 312 on the lower side thereof, the connecting plate 313 being connected to the outside of the track, the frame 310 can be a plate piece bent multiple times, or can be assembled by multiple plate pieces, and the top plate 311, the side plate 312 and the connecting plate 313 are fixed as a whole by screwing and the like.
