Description

Technical Field

[0001] This utility model relates to the field of vibration damping bearing technology, and in particular to a bridge vibration damping bearing. Background Technology

[0002] Bridge vibration damping bearings are an important component of bridge structures. Their main function is to reduce bridge vibrations under external forces such as earthquakes and wind, thereby protecting the bridge structure from damage. The design and selection of vibration damping bearings are crucial to ensuring the safety and stability of bridges.

[0003] Existing bridge vibration damping bearings typically only provide vertical damping, and are not effective at damping lateral swaying forces. This results in lateral vibration energy being directly transmitted to the main bridge structure, increasing the risk of bridge tilt. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing bridge vibration damping bearings typically only provide vertical damping and are not effective against lateral swaying forces, leading to the direct transmission of lateral vibration energy to the main bridge structure and increasing the risk of beam tilting. Therefore, this invention proposes a bridge vibration damping bearing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bridge vibration damping bearing, comprising a vibration damping bearing assembly, a protective component provided on the outer side of the vibration damping bearing assembly, a transverse vibration damping component provided at the bottom of the vibration damping bearing assembly, the vibration damping bearing assembly comprising a top plate and a base, a support seat provided on the top of the base, a rubber vibration damping pad provided on the top of the support seat, the transverse vibration damping component comprising a mounting box, an mounting groove provided on the inner side of the mounting box, a vibration damping spring provided inside the mounting groove, and a push plate connected to one end of the vibration damping spring.

[0006] Preferably, the protective component includes a rubber bellows, with sealing gaskets provided at both the top and bottom of the rubber bellows, and sealing rings provided on the sealing gaskets.

[0007] Preferably, the push plate is connected to the base, and a protective cover is provided on the top of the mounting box.

[0008] Preferably, the top of the base is symmetrically provided with telescopic columns, the top of the telescopic columns is connected to the bottom of the top plate, and the top plate is provided with mounting bolts.

[0009] Preferably, the mounting box has multiple drainage holes.

[0010] Preferably, an mounting plate is installed on the outside of the mounting box, and multiple fixing bolts pass through the interior of the mounting plate.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the base is placed inside the mounting box, which facilitates the connection between the push plate and the base. When subjected to lateral impact, the shock-absorbing spring, in conjunction with the internal buffer damper, helps the shock-absorbing spring absorb and disperse the impact force, reducing the direct impact force on the shock-absorbing support assembly, thereby improving the shock absorption efficiency and achieving buffering and shock absorption of lateral impact. When the load disappears, the shock-absorbing spring releases its elastic potential energy, pushing the push plate back to its initial position.

[0012] 2. In this utility model, a rubber corrugated tube is sleeved on the outside of the support base and the rubber shock-absorbing pad. The rubber corrugated tube is made of rubber material, which is conducive to the synchronous expansion and contraction when the rubber shock-absorbing pad is compressed vertically. This is beneficial to the protection of the rubber shock-absorbing pad, reducing the erosion of the external environment and extending the service life. The sealing gasket and sealing ring are conducive to further sealing, further improving the protective performance, thereby improving the shock absorption efficiency and realizing the buffering and shock absorption of lateral impact.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1: As Figures 1-4 As shown, this utility model provides a technical solution: a bridge vibration damping bearing, including a vibration damping bearing assembly 1, a protective assembly 2 provided on the outer side of the vibration damping bearing assembly 1, and a transverse vibration damping assembly 3 provided at the bottom of the vibration damping bearing assembly 1. The vibration damping bearing assembly 1 includes a top plate 101 and a base 105. A support seat 102 is provided on the top of the base 105, and a rubber vibration damping pad 103 is provided on the top of the support seat 102. The transverse vibration damping assembly 3 includes a mounting box 301, and a mounting groove 303 is formed on the inner side of the mounting box 301. The mounting box 301 is equipped with a shock-absorbing spring 302. One end of the shock-absorbing spring 302 is connected to a push plate 304. The push plate 304 is connected to the base 105. The top of the mounting box 301 is equipped with a protective cover 305. The top of the base 105 is symmetrically equipped with telescopic columns 104. The top of the telescopic columns 104 is connected to the bottom of the top plate 101. The top plate 101 is equipped with mounting bolts. The mounting box 301 is provided with multiple drainage holes 308. The mounting plate 306 is installed on the outside of the mounting box 301. Multiple fixing bolts 307 pass through the inside of the mounting plate 306.

[0018] In this embodiment, by connecting the top plate 101 to the bridge, the support base 102 provides stable support for the bridge. The rubber damping pad 103 is placed on top of the support base 102 to provide vertical buffering. The telescopic column 104 helps to accurately control displacement, prevent excessive deformation, and provide guidance. The base 105 is placed inside the mounting box 301, which helps to connect the push plate 304 to the base 105. When subjected to lateral impact, the damping spring 302, in conjunction with the internal buffer damper, helps to absorb and disperse the impact force, reducing the direct impact force on the damping support assembly 1, thereby improving the damping efficiency and achieving buffering and damping of lateral impact. When the load disappears, the damping spring 302 releases elastic potential energy, pushing the push plate 304 back to the initial position. The fixing bolt 307, in conjunction with the mounting plate 306, facilitates the fixed installation of the damping support assembly 1.

[0019] Example 2: As Figures 1-4 As shown, the protective component 2 includes a rubber bellows 201, with sealing gaskets 202 at both the top and bottom of the rubber bellows 201, and sealing rings 203 on the sealing gaskets 202.

[0020] In this embodiment, a rubber bellows 201 is sleeved on the outside of the support base 102 and the rubber damping pad 103. The rubber bellows 201 is made of rubber, which is beneficial for the rubber damping pad 103 to expand and contract simultaneously when it is compressed vertically. This is beneficial for protecting the rubber damping pad 103, reducing the erosion of the external environment, and extending its service life. The sealing gasket 202, together with the sealing ring 203, is beneficial for providing a sealing effect, further improving the protective performance, and thus improving the damping efficiency.

[0021] The working principle of this embodiment is as follows: In use, the top plate 101 is first connected to the bridge. The support base 102 provides stable support for the bridge. The rubber shock-absorbing pad 103 is placed on top of the support base 102 to provide vertical buffering. The telescopic column 104 helps to precisely control displacement, prevent excessive deformation, and also provides guidance. The base 105 is placed inside the mounting box 301, facilitating the connection between the push plate 304 and the base 105. When subjected to lateral impact, the shock-absorbing spring 302, in conjunction with the internal buffer damper, helps to... The shock-absorbing spring 302 absorbs and disperses the impact force, reducing the direct impact force on the shock-absorbing support assembly 1, thereby improving the shock absorption efficiency and achieving buffering and shock absorption against lateral impacts. The rubber bellows 201 is sleeved on the outside of the support 102 and the rubber shock-absorbing pad 103. The rubber bellows 201 is made of rubber, which is conducive to simultaneous expansion and contraction when the rubber shock-absorbing pad 103 is vertically compressed, which is beneficial to providing protection for the rubber shock-absorbing pad 103. The sealing gasket 202, together with the sealing ring 203, is conducive to further providing a sealing effect, further improving the protective performance, and thus improving the shock absorption efficiency.

[0022] The shock-absorbing spring 302 in this utility model is common knowledge in the field. Its working principle is a well-known technology. The appropriate model is selected according to actual use. Therefore, the shock-absorbing spring 302 will not be explained in detail.
