[0023] Example 1, as Figure 1 As shown:

[0024] A wheelset inspection machine includes a base 1. A crossbeam 6 is supported at the top of the base 1 by two columns 2.

A high-precision measuring wheel 84 is installed at the end of the measuring wheel mounting block 82. A displacement sensor 3 85 is installed on the side of the probe base plate 81 above the measuring wheel mounting block 82.

[0032] Example 5, as Figure 8 As shown:

[0033] The wheelset limiting device 11 includes a limiting wheel 111 mounted on a base 1 inside the travel track 13, and limiting cylinders 114 symmetrically mounted on the bottom of the base 1 outside the travel track 13.

A baffle cylinder 113 is mounted on the outer surface of the travel track 13 via a rotating seat. The output end of the baffle cylinder 113 is connected by a pin to a wheelset baffle 112 rotatably mounted on the travel track 13. By controlling the operation of the limiting cylinders 114, the limiting blocks 115 are lifted, thereby limiting the wheelset. After the wheelset on the travel track 13 reaches the measurement area, the operation of the baffle cylinders 113 is controlled to raise the wheelset baffle 112, thereby preventing the wheelset from slipping off the travel track 13 and improving safety.

[0034] Example 6, as Figure 6 As shown:

[0035] The wheelset lifting device 12 includes a lifting base plate 1201 fixed to the base 1 by a hydraulic buffer 1207. A hydraulic cylinder mounting plate 1202 is connected to the surface of the lifting base plate 1201 via a lifting guide shaft 1210. A lifting moving plate 1204 is connected to the surface of the hydraulic cylinder mounting plate 1202 via a linear bearing 1203. Roller seats 1205 are distributed on the surface of the lifting moving plate 1204, and rollers 1206 are installed inside the roller seats 1205. A hydraulic cylinder connecting block 1209 is installed at the bottom end of the lifting moving plate 1204. A lifting hydraulic cylinder 1208 is installed inside the hydraulic cylinder mounting plate 1202. The output end of the lifting hydraulic cylinder 1208 passes through and extends to the top of the hydraulic cylinder mounting plate 1202 and is connected to the hydraulic cylinder connecting block 1209. When the limit cylinder 114 is working, the lifting hydraulic cylinder 1208 works synchronously, thereby placing the wheelset axle between the two rollers 1206, thus supporting the wheelset. This ensures that the wheelset can rotate smoothly and will not fall off, thereby improving safety.
