[0029] As Figures 1-5As shown, the detection platform 2 includes a horizontal plate 21 and a vertical plate 22. One end of the vertical plate 22 is mounted on one end of the horizontal plate 21. The extension direction of the vertical plate 22 is perpendicular to the extension direction of the horizontal plate 21. The vertical plate 22 is set along the direction of gravity. The detection carrier is mounted on the horizontal plate 21. The detection carrier is used to detect the axle. The detection carrier can be detected using at least one of a phased array ultrasonic probe or a conventional ultrasonic probe.
[0030] like Figures 1-5 As shown, one end of the first connecting rod 3 is rotatably mounted on the end of the vertical plate 22 away from the horizontal plate 21, and the other end of the first connecting rod 3 away from the horizontal plate 21 is mounted on the mounting block 1. The first connecting rod 3 is used to support one end of the detection platform 2, as shown. Figure 1 As shown, after the axle inspection is completed, the first connecting rod 3 rotates in the x-direction, and the inspection platform 2 remains horizontal. The angle between the axial direction of the first connecting rod 3 and the horizontal plate 21 gradually decreases. The two ends of the first connecting rod 3 rotate relative to the horizontal plate 21 and the mounting block 1, respectively. After the axial direction of the first connecting rod 3 is parallel to the horizontal plate 21, the first connecting rod 3 stops rotating. The first connecting rod 3 is located between the horizontal plate 21 and the mounting block 1, thereby increasing the distance between the inspection platform 2 and the bottom of the train, reducing the impact of the inspection platform 2 on the train during operation, and reducing the impact or entanglement of the inspection carrier by foreign objects wrapped around the axle. When it is necessary to inspect the train axle, the first connecting rod 3 rotates in the opposite direction, pushing the inspection platform 2 to move closer to the axle to facilitate the inspection of the axle.

The connecting rod 5 is used to support the other end of the detection platform 2 away from the first connecting rod 3. Through the first connecting rod 3 and the connecting rod 5, both ends of the detection platform 2 are supported, so that the horizontal plate 21 of the detection platform 2 always remains horizontal. The second connecting rod 4 rotates, thereby driving the connecting rod 5 to rotate. The rotation of the first connecting rod 3, the second connecting rod 4, and the connecting rod 5 drives the detection platform 2 to move along the first direction, which is parallel to the direction of gravity. Figure 1 As shown, the first direction is the direction of the y-axis, and the horizontal plate 21 is perpendicular to the first direction.

When the vehicle axle needs to be detected, the second connecting rod 4 reversely rotates to support the detection platform 2 to move close to the vehicle axle.
