[0023] Embodiment one: refer to Figures 1-4 As shown: a kind of self-adapting damping device for wheel cage, including cage main body 1, cage main body 1 side is fixedly connected with guardrail 2, guardrail 2 bottom is provided with damping mechanism, damping mechanism includes bottom plate 4, air spring assembly 9 and connecting plate 16, bottom plate 4 top is fixedly connected with buffer pad 18, buffer pad 18 top is fixedly connected with connecting plate 16, connecting plate 16 top is hinged with telescopic rod 19, telescopic rod 19 top is hinged with buffer 15, buffer 15 and connecting plate 16 between installation coil spring 17, buffer 15 top is fixedly connected with buffer plate 3, buffer plate 3 top is fixedly connected with air spring assembly 9, and buffer plate 3 is internally inserted with vertical plate 14, vertical plate 14 and buffer plate 3 between slidingly connected, vertical plate 14 bottom is fixedly connected with bottom plate 4, buffer plate 3 top is fixedly connected with plug-in strip 10, plug-in strip 10 inside slidingly connected with guide bar 5, guide bar 5 top is fixedly connected with support frame 7.

[0024] The connection between the base plate 4 and the connecting plate 16 is achieved through the buffer pad 18, and the connection between the buffer component 15 and the connecting plate 16 is achieved through the telescopic rod 19 and the coil spring 17. When the buffer component 15 is subjected to external force, the bottom of the buffer component 15 is buffered and protected by the coil spring 17 and the telescopic rod 19. The buffer component 15 can also buffer the bottom of the buffer plate 3. The air spring assembly 9 connects the mounting plate 6 and the buffer plate 3, which can provide initial buffering for the bottom of the support frame 7. The air spring assembly 9 is filled with gas at a certain pressure. When the cage body 1 is vibrated, the gas in the air spring assembly 9 is compressed or expanded, and the vibration energy is absorbed and buffered through the elastic deformation of the gas. At the same time, the stiffness of the air spring assembly 9 can be changed by adjusting the air pressure, thereby adapting to different loads and vibration conditions. The stiffness is automatically adjusted according to the load, and the self-adaptive ability is strong, which can improve the shock absorption effect of the cage body 1 and reduce the damage to the bottom of the cage body 1 during use.

The bottom of the mounting plate 6 is fixedly connected to the air spring assembly 9. The mounting plate 6 is connected to the support frame 7 by bolts.

[0026] The plug strip 10 can be used to support one side of the horizontal plate 11. The sliding connection between the horizontal plate 11 and the side plate 8 can guide the installation of the buffer plate 3 at the bottom of the support frame 7. The auxiliary strip 12 and the side plate 8 are connected by the limit bolt 13.
