[0022] See also Figure 1-4 As shown, the utility model provides a technical solution: a bridge pile foundation protection device, including a buffer mechanism 2, the buffer mechanism 2 is composed of two groups of buffer parts, the two groups of buffer parts are both sleeved and fixed on the bridge pile foundation 1, the buffer parts include a fixed component 21, a secondary buffer component 22 and a primary buffer component 23, the fixed component 21 includes a semi-cylinder 211 and a groove bar 212.
[0023] Furthermore, a friction pad 3 is provided on the inner side of the semi-cylinder 211, and a friction pattern 31 is provided on the inner side of the friction pad 3. The friction pad 3 provided on the inner side of the semi-cylinder 211 can avoid wear of the semi-cylinder 211, and the friction pattern 31 provided on the friction pad 3 increases the friction between the semi-cylinder 211 and the bridge pile foundation 1.

The corresponding grooves 212 are provided with slide grooves 2121 facing each other. Multiple groups of grooves 212 are correspondingly installed with multiple groups of primary buffer components 23 and secondary buffer components 22, so that the device can perform multi-directional impact buffering on the side of the bridge pile foundation 1. The two groups of grooves 212 with slide grooves 2121 facing each other can ensure that the slider 221 maintains vertical movement.
[0026] Furthermore, the secondary buffer component 22 includes a slider 221, a connecting ear 222 and a spring 223. The slider 221 slides along the slide groove 2121 through the connecting ear 222, and the connecting ears 222 are fixedly connected to both sides of the slider 221, and the springs 223 are fixedly connected to both ends of the connecting ears 222, and the springs 223 are fixedly connected to the groove 212. The springs 223 and the groove bar 212 are fixedly connected.

The springs 223 at the two positions buffer the impact force synchronously, which greatly improves the buffering and anti-collision capabilities of the device. Similarly, when the impact force is directed upward, the slider 221 will move upward along the slide groove 2121, and the spring 223 under the slider 221 will be stretched, and the spring 223 above the slider 221 will be compressed.

One side of the No. 1 connecting rod 231 is fixedly connected to the hydraulic cylinder 234, and the movable end of the hydraulic cylinder 234 is fixedly connected to the No. 2 connecting rod 232. When the strike plate 233 receives an external impact, the strike plate 233 will rotate according to the direction of the force and remain perpendicular to the force application direction.

In the second step, multiple groups of grooves 212 are correspondingly installed with multiple groups of primary buffer components 23 and secondary buffer components 22, so that the device can perform multi-directional impact buffering on the side of the bridge pile foundation 1. Two groups of grooves 212 with sliding grooves 2121 facing each other can ensure that the slider 221 maintains vertical movement. When the impact plate 233 receives external impact, the impact plate 233 will rotate according to the direction of the force and remain perpendicular to the direction of the force, and at the same time, the second connecting rod 232 will rotate relative to The No. 1 connecting rod 231 rotates and compresses the hydraulic cylinder 234 to perform the first preliminary buffering.
