Description

Technical Field

[0001] This utility model relates to the technical field of bridge bearings, and in particular to a bridge bearing with a shock-absorbing support structure. Background Technology

[0002] Bridges generally consist of a superstructure, substructure, bearings, and ancillary structures. Bridge bearings are important components that connect and constrain the superstructure and substructure of a bridge, and are an indispensable part of the bridge's load-bearing capacity.

[0003] A search revealed Chinese Patent Publication No. CN220246662U, which discloses a bridge anti-falling beam structure. From top to bottom, it includes a beam body, support units, and piers. The support unit, from top to bottom, includes an upper support and a lower support. A spherical crown is provided between the bottom middle of the upper support and the top middle of the lower support. U-shaped steel structural members are provided at both ends of the support unit. The U-shaped steel structural members include connecting U-shaped plates and connecting straight plates located at the top and bottom ends of the connecting U-shaped plates. The connecting straight plates can be fixed to the beam body via the left and right ends of the upper support or to the pier via the left and right ends of the lower support. In the event of an earthquake, the connecting U-shaped plates between the two connecting straight plates of the U-shaped steel structural members provide a certain elastic buffer space, which can greatly reduce the probability of beam falling.

[0004] Existing bridge bearing structures have anti-fall beams installed between the upper and lower bearings for elastic buffering. However, there is a lack of supporting connection structure between the upper and lower bearings on the outer side of the spherical crown. This results in relatively poor support performance between the spherical crown and the upper and lower bearings inside the anti-fall beam in some working scenarios where the upper and / or lower bearings on the outer side of the spherical crown are relatively long.

[0005] In view of the above-mentioned shortcomings, the designer has actively researched and innovated in order to create a bridge bearing with a shock-absorbing support structure, which will make it more valuable for industrial use. Utility Model Content

[0006] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a bridge bearing with a shock-absorbing support structure.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A bridge bearing with a vibration damping support structure includes, from top to bottom, a beam, a bearing unit and a pier. The bearing unit includes, from top to bottom, an upper bearing and a lower bearing. A spherical crown is provided between the bottom of the middle end of the upper bearing and the top of the middle end of the lower bearing. Both the left and right ends of the bearing unit are connected to anti-fall beams with U-shaped structures.

[0009] Upper support frames are provided at the bottom of the upper supports near the left and right sides of the spherical crown, and lower support frames are provided on the lower supports below the upper support frames, and a support contact structure is provided between the upper support frames and the lower support frames to provide upper and lower support.

[0010] A sliding connection structure is provided between the upper or lower support frame and the inner lower support. The sliding connection structure includes a transmission block. The inner side of the transmission block is movably mounted on the lower support, and a spherical contact end that contacts the lower support is provided on the inner side of the transmission block.

[0012] As a further improvement of this utility model, a support block is provided at the bottom of the upper support frame, and a support block is provided on the lower support frame below the support block.

[0013] As a further improvement of this utility model, a first sliding contact friction pair distributed along the horizontal direction is provided between the two support blocks.

[0014] As a further improvement of this utility model, the first sliding contact friction pair is mounted on the upper or lower support block.

[0015] As a further improvement of this utility model, a second sliding contact friction pair is provided on the outer side of the conductive block, which is distributed along the vertical direction and contacts the upper or lower support frame on the outer side.

[0016] As a further improvement of this utility model, the transmission block is installed together with the lower support by a pin. The inner side of the transmission block is provided with a movable groove and a first connecting hole in sequence from the outside to the inside. The lower support is provided with a second connecting hole and an embedding groove in sequence from the outside to the inside.

The outer side of the pin passes through the first connecting hole and is then movably installed in the movable groove by the movable block. A movable gap is provided between the movable block and the movable groove.

[0017] As a further improvement of this utility model, an elastic pad is installed in the movable gap within the movable groove.

[0018] By means of the above solution, this utility model has at least the following advantages:

[0019] This invention improves the support performance between the upper and lower supports through the support contact structure between the upper and lower supports. The upper or lower support frame is further connected to the lower support through a sliding connection structure, which can accommodate sliding in the vertical direction.

[0020] This invention can adapt to sliding in the horizontal direction by using a first sliding contact friction pair between the upper support block and the lower support block.

[0030] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0031] The first embodiment of this utility model:

[0032] like Figure 1 As shown, a bridge bearing with a vibration damping support structure mainly includes a beam 1, an upper bearing 2, a spherical crown 4, a pier 6, a lower bearing 7, and an anti-fall beam 8. The upper bearing 2 is installed at the bottom of the beam 1, and the lower bearing 7 is installed on the pier 6 below the upper bearing 2. A spherical crown 4 is provided between the upper bearing 2 and the lower bearing 7. An upper spherical crown friction pair 3 distributed horizontally is provided between the bottom of the middle of the upper bearing 2 and the top of the spherical crown 4. A lower spherical crown friction pair 5 with a spherical structure is provided between the top of the middle of the lower bearing 7 and the bottom of the spherical crown 4.

[0033] 1. The upper support 2 and the lower support 7 constitute a support unit. U-shaped anti-fall beams 8 (which can be steel structures) are connected to both ends of the support unit. The top end of the anti-fall beam 8 is installed on the outside of the upper support 2, and the bottom end of the anti-fall beam 8 is installed on the outside of the lower support 7. Through the aforementioned anti-fall beam 8 structure, beam collapse can be prevented to a certain extent during an earthquake.

[0034] Second, a sliding connection structure is also provided between the upper support 2 and the lower support 7 on the inner side of the spherical crown 4 and the anti-fall beam 8, which can further support the upper support 2 and the lower support 7.

[0035] 1. Upper support frames 9 are vertically distributed at the bottom of the upper supports 2 on both sides near the spherical crown 4. Lower support frames 10, also vertically distributed, are installed on the lower supports 7 directly below the upper support frames 9. A support contact structure 11, providing vertical support, is provided between the upper support frames 9 and the lower support frames 10. The support blocks 13 at the bottom of the upper support frames 9 and at the top of the lower support frames 10 provide support between the upper supports 2 and the lower supports 7, thereby improving their support performance. Figure 2 .

[0036] Furthermore, a first sliding contact friction pair 14, which can be slidably mounted horizontally, is provided between the two support blocks 13, allowing the two support blocks 13 to slide in the horizontal direction to a certain extent, thereby adapting to sliding in the horizontal direction. The aforementioned sliding in the horizontal direction can be as follows: Figure 1 The left-right or front-back directions shown can be reasonably arranged and adjusted according to the actual situation. The first sliding contact friction pair 14 mentioned above can also be installed on the upper or lower support block 13 according to specific usage requirements.

[0037] 2. A sliding connection structure 12 is provided between the upper support frame 9 or the lower support frame 10 and the inner lower support 7, wherein, for example... Figure 1 As shown, a sliding connection structure 12 can be provided between the bottom inner side of the upper support frame 9 and the inner lower support 7, or a sliding connection structure 12 can be provided between the top inner side of the lower support frame 10 and the inner lower support 7. The arrangement and adjustment can be made reasonably according to the actual situation.

[0038] The aforementioned sliding connection structure 12 includes a transmission block 15. The inner side of the transmission block 15 is movably mounted on the lower support 7. Then, the outer side of the transmission block 15 contacts the outer upper support frame 9 or the outer lower support frame 10 through the second sliding contact friction pair 16. That is, the second sliding contact friction pair 16 makes sliding contact with the outer upper support frame 9 or the outer lower support frame 10 in the vertical direction.

[0039] The conductive block 15 has a structure that allows it to slide vertically against the outer upper support frame 9 or lower support frame 10 via the second sliding contact friction pair 16, enabling it to adapt to vertical sliding. The conductive block 15 also has a structure that allows it to rotate within a certain range by contacting the lower support 7 via the spherical contact end 25. Furthermore, an arc-shaped contact structure can be designed at the point where the spherical contact end 25 contacts the lower support 7 to facilitate better contact between the two.

[0040] like Figure 3 One type of movable mounting structure for the conductive block 15 on the lower support 7:

[0041] The conductive block 15 is mounted on the lower support 7 along the front-back direction via a pin 21. The middle part of the pin 21 can be located in the first connecting hole 18 and the second connecting hole 19 respectively. The inner side of the pin 21 has an embedded block 22 embedded in the contoured embedded groove 20, and this end is tightly installed and cannot move. The outer side of the pin 21 has a movable block 23 installed in the movable groove 17 of the conductive block 15. The movable groove 17 is provided with a movable gap that allows the movable block 23 to move freely within a certain range, so that the conductive block 15 can move freely relative to the lower support 7 within a certain range. Then, the structure of contact between the conductive block 15 and the lower support 7 through the ball contact end 25 facilitates the above-mentioned movement process.

[0042] An elastic pad 24 (which can be an elastic material with a rubber structure) is installed in the movable gap between the movable block 23 and the movable groove 17, so that the movable block 23 can have a soft contact with the movable groove 17 during the movement, thereby reducing the wear on the movable block 23 to a certain extent.
