[0032] The car body mounting member 1 and the axle mounting member 4 are respectively mounted on the car body and the axle, and the other side of the car body mounting member 1 and the axle mounting member 4 respectively forms a car body sensor 6 mounting position and an axle sensor 7 mounting position; the angle adjustment plate 2 is rotatably mounted on the car body sensor 6 mounting position of the car body sensor 6 for mounting the car body sensor 6, so that the car body sensor 6 adjusts its alignment angle through the rotation of the angle adjustment plate 2, so as to adapt to different use environments; the adjustment fixing member 3 is connected with the angle adjustment plate 2, for adjusting the angle adjustment plate 2 to switch between the rotating state and the fixed state, so as to fix the angle adjustment plate 2 after adjusting the angle.
[0033] In some embodiments, as Figure 3As shown, the axle mounting member 4 comprises an axle connecting body 41 and an axle mounting rack; the axle connecting body 41 is fixed on the axle; the axle mounting rack is detachably mounted on the axle connecting body 41 and forms an axle sensor 7 mounting position. In the embodiment, the axle connecting body 41 is the axle connecting body 41 which can be fixed on the axle by welding, thereby facilitating the installation of the axle mounting rack. The axle mounting rack is detachably mounted on the axle connecting body by bolts.
[0034] Further, the axle mounting rack comprises an axle connecting portion, a supporting portion and a sensor mounting portion which are integrally formed; the axle connecting portion is detachably mounted on the axle connecting body 41 and connected with the supporting portion through a plurality of reinforcing ribs; the supporting portion and the axle connecting portion have an included angle therebetween so as to facilitate the sensor mounting portion to be located at the axle; a plurality of threaded holes are formed in the sensor mounting portion so as to facilitate the axle sensor 7 to be mounted on the sensor mounting portion by bolts.
[0035] In some embodiments, as shown, Figure 2 In order to facilitate the installation of the vehicle body mounting member 1, the vehicle body mounting member 1 comprises a vehicle body mounting rack 12 and a mounting shell 13; the vehicle body mounting rack 12 is detachably mounted on the vehicle body; the mounting shell 13 is detachably mounted on the vehicle body mounting rack 12 and forms a vehicle body sensor 6 mounting position. The detachable mounting of the vehicle body mounting rack 12 and the vehicle body can adopt bolt mounting, which has stability and facilitates disassembly and assembly; the mounting of the mounting shell 13 and the vehicle body mounting rack 12 can also adopt bolt mounting.
[0036] In the embodiment, the mounting shell 13 is divided into two vehicle body sensor 6 mounting positions by the partition plate 5; two angle adjustment plates 2 corresponding to the number of vehicle body sensor 6 mounting positions are configured to respectively install two vehicle body sensors 6; one vehicle body sensor 6 is used for monitoring the rail, and the other vehicle body sensor 6 is used for monitoring the wheel rim, so that the rail and the wheel rim can be monitored at the same time, and the two vehicle body sensors 6 can adjust the alignment angle through the angle adjustment plates 2, thereby improving the applicability. The rotation axes of the two angle adjustment plates 2 are arranged perpendicular to each other, so that the vehicle body sensors 6 mounted on the angle adjustment plates 2 are respectively aligned with the rail and the wheel rim; through the perpendicular angle adjustment plates 2, the adjustment angles of the two angle adjustment plates 2 cover the X-axis and the Y-axis, so that the vehicle body sensors 6 can be conveniently aligned with the rail and the wheel rim after installation, thereby improving the monitoring convenience.
[0037] Further, the cross section of the vehicle body mounting rack 12 is triangular, specifically a right-angled triangle, and the first right-angled side of the vehicle body mounting rack 12 is connected with the mounting shell 13, and the second right-angled side is connected with the vehicle body, so that the two ends of the hypotenuse of the vehicle body mounting rack 12 are respectively connected with the vehicle body and the mounting shell 13, thereby facilitating uniform stress and improving the stability of the installation.
