[0024] It needs to be explained here: the rotation of the first tooth ring 502 can drive the second tooth ring 602 and the second rotating roller 601 to rotate.

[0025] In a preferred embodiment, the clamping assembly 7 includes a rack 701, a limiting groove 702 opened on the bottom outer wall of the rack 701, a bracket 703 installed on the top of the rack 701, a spring assembly 704 movably inserted into the outer wall of one side of the bracket 703 at both ends, and a clamping plate 705 installed on the two spring assemblies 704.

[0031] Working principle: The track 12 can be installed on the fixed plate 3. When the train passes through the current track 12, the impact of the wheel on the track 12 makes the track 12 vibrate. The damping support 2 can passively damp the track 12. The vibration sensor 4 can monitor the vibration amplitude of the track 12. When the train is about to pass through the track 12, it will cause small vibration of the track 12, which is monitored by the vibration sensor 4. After that, the vibration sensor 4 transmits a signal to the controller 10, and the controller 10 starts the motor 9 to drive the gear 11 to rotate, and then drives the first tooth ring 502 to rotate, and then drives the second tooth ring 602 to rotate.

The elastic assembly 704 can play a buffering role when the clamping plate 705 contacts the track 12. By clamping the current track 12 in advance, the lateral and longitudinal displacement of the track 12 under the action of the train load is reduced, so that the track 12 maintains a more stable state, reduces the vibration caused by the shaking and displacement of the track 12, and thus reduces the propagation and amplification of the vibration, actively improves the stability of the track 12, and achieves the effect of vibration reduction, further improving the vibration reduction effect.
