They can reliably transfer the load and deformation (displacement and rotation) borne by the superstructure of the bridge to the substructure of the bridge. They are important force transmission devices of the bridge. There are two types of bearings: fixed bearings and movable bearings. The commonly used bearing types in bridge engineering include: felt or flat bearings, plate rubber bearings, spherical bearings, steel bearings and special bearings.

Therefore, the shock-absorbing bearings need to achieve buffering and shock absorption in all directions, otherwise the shock absorption effect may be poor.

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figure 1 A damping shock-absorbing support structure in this embodiment includes a lower support 1, a connecting plate 2 is fixed to the upper surface of the lower support 1, an upper support 3 is slidably connected to the outer side of the connecting plate 2, and a shock-absorbing mechanism 4 for shock absorption is provided between the connecting plate 2 and the upper support 3.
[0022] It should be noted that the shock absorbing mechanism 4 can convert the external force received by the device into power, and then buffer and offset the power through friction and elastic force, thereby reducing the shaking amplitude of the device itself, ensuring the stability of the device, and further improving the shock absorbing effect of the device.
[0023] See also Figure 1-3 In order to improve the shock absorption effect of the device, the first buffer component in this embodiment includes a fixed rod 401 fixed to the middle of the inner bottom wall of the connecting plate 2. The cross section of the fixed rod 401 is T-shaped. The outer surface of the fixed rod 401 is slidably connected with a first slider 402. Connecting rods 403 are fixed on both sides of the upper surface of the first slider 402. The top of the connecting rod 403 is fixed to the inner top wall of the upper support 3, so that the upper support 3 can drive the connecting rod 403 to move when the force is applied to the upper support 3, thereby driving the movement. The cross sections of the connecting plate 2 and the upper support 3 are both U-shaped. The upper surface of the first slider 402 is fixed with a sleeve that is connected to the outer surface of the fixed rod 401 and the top is fixed to the inner top wall of the upper support 3. A first shock-absorbing spring 404 is fixed to the top of the fixed rod 401, and a first friction pad 405 is fixed to the outer surface of the fixed rod 401. The first buffer assembly also includes four dampers 411 whose two ends are respectively fixed to the inner top wall of the upper support 3 and the inner bottom wall of the connecting plate 2. The damper 411 is used to partially buffer and offset the force applied to the upper support 3. Then, when the first slider 402 moves, the first friction pad 405 generates friction to hinder the movement of the first slider 402. The elastic force generated by the first shock-absorbing spring 404 offsets the power generated by the movement of the first slider 402, thereby reducing the vibration amplitude of the device itself to a certain extent.
[0024] Among them, the second buffer assembly includes four cross bars 406 fixed between the fixed rod 401 and the inner wall of the connecting plate 2, the outer surface of the cross bar 406 is slidably connected with the second slider 407, the outer surface of the cross bar 406 is sleeved with a second shock-absorbing spring 408, the outer surface of the cross bar 406 is fixed with a second friction pad 409, the top of the second slider 407 is hinged with a hinge rod 410, the two ends of the second shock-absorbing spring 408 are respectively fixed to the inner wall of the connecting plate 2 and the side of the second slider 407 close to the inner wall of the connecting plate 2, the lower surface of the second slider 407 slides in contact with the inner bottom wall of the connecting plate 2, and the second friction pad 409 and the second slider 407 of the connecting plate 2 When the second slider 407 moves, the friction force generated by the movement of the second friction pad 409 and the second slider 407 of the connecting plate 2 can partially offset the power of the second slider 407, and at the same time, the elastic force generated by the compression of the second shock-absorbing spring 408 further buffers and offsets the power of the second slider 407, thereby further improving the anti-seismic effect of the device.
[0025] At the same time, the top of the hinged rod 410 is hinged to the outer side of the first slider 402, and the outer side of the first slider 402 and the upper surface of the second slider 407 are fixed with hinged seats. The two hinged seats are hinged to the two ends of the hinged rod 410 through pins respectively, so that after the first slider 402 is moved by force, it can drive the second slider 407 to move through the hinged rod 410, thereby dispersing and offsetting the force received to a greater extent.
[0026] In addition, the guide assembly includes a guide groove 412 opened on the left and right sides of the connecting plate 2, and the inner wall of the guide groove 412 is slidably connected with a guide slider 413. The opposite sides of the two guide grooves 412 are respectively fixed to the left and right sides of the inner wall of the upper support 3, so that the upper support 3 can ensure directional movement to a certain extent after being subjected to force, thereby preventing the upper support 3 from shaking excessively to the left and right.
[0027] It should be noted that the directional movement of the force applied to the upper support 3 is ensured by the guide assembly, and the force applied to the upper support 3 is dispersed and offset to a greater extent by the second buffer assembly and the first buffer assembly, so as to improve the shock absorption effect of the device.
[0028] The working principle of the above embodiment is:
[0029] When subjected to external impact, the upper support 3 moves under the external force, thereby driving the guide slider 413 to move along the guide slide groove 412, which ensures the directional movement of the upper support 3 to a certain extent and prevents the upper support 3 from shaking left and right. At the same time, the damper 411 can perform a vibration reduction action and play a certain buffering role, thereby reducing the amplitude of the upper support 3. The movement of the upper support 3 drives the connecting rod 403 to move, thereby prompting the first slider 402 to move and generate power. At this time, the first shock-absorbing spring 404 will generate an elastic force corresponding to the power. At the same time, because the first slider 402 moves, it will produce a first friction pad 405 on the outer surface of the fixed rod 401. The friction force will form a resistance to prevent the first slider 402 from moving, which further plays a role in buffering and shock absorption. At the same time, the movement of the first slider 402 will drive the hinge rod 410 to move, and then the second slider 407 moves along the cross bar 406 to generate power. At this time, the second friction pad 409 located on the outer surface of the cross bar 406 generates friction with the second slider 407, and the second shock-absorbing spring 408 generates elastic force. The friction force and the elastic force buffer and offset the power generated by the second slider 407. Under the cooperation of each other, the external force exerted on the device can be offset to the greatest extent, the impact force can be buffered and unloaded, the shock absorption performance is improved, and the stability of the device is guaranteed.
