The second buffer assembly 5 includes two slide bars 501. The surfaces of the two slide bars 501 are slidably connected with a slider 502. The surface of the slider 502 is movably connected with a movable rod 503 through a rotating shaft. The other end of the movable rod 503 is fixedly connected to the concave frame 301 through a rotating shaft. The surface of the slide bar 501 is sleeved with a second spring 504, which can further buffer and offset the longitudinal vibration generated by the bridge. The fixed plate 401 A damper 505 is fixedly connected to the bottom, and the other end of the damper 505 is fixedly connected to the bottom of the inner cavity of the concave groove 2, which can further increase the longitudinal buffering force.

[0030] The principle of this embodiment is:

[0031] When in use, the bridge is hoisted onto the supporting pad 303. At this time, the bridge will make the supporting platform 302 descend, and at the same time, it will push the concave frame 301 to move downward. The downward movement of the concave frame 301 will respectively move the sliding rod 501 downward in the sliding hole 403, and push the sliding seat 404 to squeeze the first spring 405, so that the first spring 405 is in a compressed state. At the same time, the concave frame 301 will also push the movable rod 503 to adjust the angle movement. The movable rod 503 will push the slider 502 to move left and right on the surface of the sliding rod 501, squeezing the second spring 504. The second spring 504 will also be in a compressed state, and the arrangement of the first spring 405 and the second spring 504 is conducive to further absorbing the load, improving the shock absorption of the bridge, being able to support the bridge, and being able to buffer and offset the longitudinal vibration generated by the bridge. When the bridge vibrates laterally due to an earthquake, the support pad 303 will drive the movable block 305 to move in the movable groove 304, and the movement of the movable block 305 can cause deformation to the third spring 306. At this time, the third spring 306 can buffer and offset the lateral vibration generated by the bridge during use, thereby increasing the service life of the bridge.

[0032] To sum up: this type of bridge bearing, by setting up a supporting component 3, can support the bridge, and at the same time can buffer and offset the lateral vibration generated by the bridge during use, thereby improving the service life of the bridge. Through the setting of the first buffer component 4, it can buffer and offset the longitudinal vibration generated by the bridge. The cooperation of the two can achieve a better earthquake-resistant effect.
