Embodiment 1
[0112] like Figure 2-6 As shown, three laser displacement sensors 2 are installed inside the track 3 along a direction parallel to the track 3 . Wherein, the included angles between the first laser displacement sensor 21, the second laser displacement sensor 22, and the third laser displacement sensor 23 and the vertical line are all 45°, that is, β 1 , β 2 , β 3 is 45°; the first laser displacement sensor 21 and the third laser displacement sensor 23 are installed at an angle of 45° to the longitudinal horizontal line along the direction of the track 3, namely α 1 、α 3 are all 45°, and the second laser displacement sensor 22 is installed parallel to the longitudinal horizontal line in the direction of the track 3, that is, α 2 is 0°.
[0113] The following only takes the second laser displacement sensor 22 as an example to obtain the lowest point of the rim of the wheel 1 measured by the second laser displacement sensor 22 .
[0114] (1) For the second laser displaceme...
