Description

Technical Field

[0001] This utility model relates to the field of bridge bearing technology, specifically to a bridge bearing with dustproof function. Background Technology

[0002] Bridge bearings, as key components connecting the superstructure and substructure of a bridge, play a vital role in bridge engineering. They not only reliably transfer the load of the superstructure to the substructure, but also accommodate displacements and rotations caused by factors such as temperature changes, concrete shrinkage and creep, and vehicle loads, ensuring the safety and normal use of the bridge structure.

[0003] In practical applications, bridge bearings operate in complex environments, often exposed to the outdoors and subject to long-term exposure to external factors such as dust, sand, rainwater, and corrosive gases. Among these, dust intrusion has a significant negative impact on the performance and service life of bridge bearings. Once dust enters the bearing, it adheres to the surfaces of various components, especially between moving parts. This easily corrodes the moving parts, accelerating their aging and damage, and affecting the stress state of the bridge structure.

[0004] Therefore, it is necessary to invent a bridge bearing with dustproof function to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bridge bearing with dustproof function, comprising a supporting top plate, a supporting bottom plate, a rubber damping core, a guide component, and a dustproof sleeve. The supporting top plate is located directly above the supporting bottom plate. The rubber damping core, the guide component, and the dustproof sleeve are all disposed between the supporting top plate and the supporting bottom plate. An upper ring plate is fixedly connected to the top of the dustproof sleeve, and the upper ring plate is fixedly installed to the bottom of the supporting top plate by screws. A lower ring plate is fixedly connected to the bottom of the dustproof sleeve, and the lower ring plate is fixedly installed to the top of the supporting bottom plate by screws. The rubber damping core and the guide component are both covered inside the dustproof sleeve.

[0007] Preferably, the dustproof sleeve is made of corrugated rubber tubing, and the dustproof sleeve can expand and contract synchronously with the expansion and contraction of the bridge bearing.

[0008] Preferably, a first limiting sleeve is fixedly connected at the center of the bottom of the supporting top plate, and the top of the rubber shock-absorbing core is sleeved inside the first limiting sleeve.

[0009] Preferably, a second limiting sleeve is fixedly connected at the top center of the support base plate, and the bottom end of the rubber shock-absorbing core is sleeved inside the second limiting sleeve.

[0010] Preferably, the guide assembly includes a telescopic rod, with a first mounting plate fixedly connected to the top end of the telescopic rod and a second mounting plate fixedly connected to the bottom end of the telescopic rod.

[0011] Preferably, the first mounting plate is fixedly installed to the bottom of the support top plate with screws, and the second mounting plate is fixedly installed to the top of the support bottom plate with screws.

[0013] Preferably, both the top and bottom support plates are provided with mounting holes, and the design of the mounting holes facilitates the fixing of the bridge support between the superstructure and substructure of the bridge using fasteners.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1.

Detailed Implementation

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model provides, for example Figure 1-5 The bridge bearing shown includes a top support plate 1, a bottom support plate 2, a rubber damping core 3, a guide assembly 4, and a dustproof sleeve 5. The top support plate 1 is located directly above the bottom support plate 2. The rubber damping core 3, the guide assembly 4, and the dustproof sleeve 5 are all disposed between the top support plate 1 and the bottom support plate 2. An upper ring plate 6 is fixedly connected to the top of the dustproof sleeve 5 and is fixedly installed to the bottom of the top support plate 1 by screws. A lower ring plate 7 is fixedly connected to the bottom of the dustproof sleeve 5 and is fixedly installed to the top of the bottom support plate 2 by screws. The rubber damping core 3 and the guide assembly 4 are both covered inside the dustproof sleeve 5. The dustproof sleeve 5 can prevent external factors such as dust, sand, and rainwater from entering the interior of the bearing, reducing component aging and damage caused by dust adhesion and erosion, thereby extending the overall service life of the bridge bearing.

[0019] In one aspect of this embodiment, the dustproof sleeve 5 is made of a corrugated sleeve of rubber material. The dustproof sleeve 5 can expand and contract synchronously with the expansion and contraction of the bridge bearing, always maintaining the sealed state inside the bridge bearing, avoiding dustproof failure caused by the deformation of the bridge bearing, and ensuring long-term dustproof effect.

[0020] A first limiting sleeve 8 is fixedly connected at the bottom center of the supporting top plate 1. The top of the rubber damping core 3 is fitted inside the first limiting sleeve 8. A second limiting sleeve 9 is fixedly connected at the top center of the supporting bottom plate 2. The bottom of the rubber damping core 3 is fitted inside the second limiting sleeve 9. Through the coordinated action of the first limiting sleeve 8 and the second limiting sleeve 9, the position of the rubber damping core 3 is fixed, preventing the rubber damping core 3 from leaving the preset working range under complex loads.

[0021] The guide assembly 4 includes a telescopic rod 10. A first mounting plate 11 is fixedly connected to the top of the telescopic rod 10, and a second mounting plate 12 is fixedly connected to the bottom of the telescopic rod 10. The first mounting plate 11 is fixedly installed at the bottom of the support top plate 1 by screws, and the second mounting plate 12 is fixedly installed at the top of the support bottom plate 2 by screws. The number of guide assemblies 4 is set to multiple, and the multiple guide assemblies 4 are distributed in a ring array outside the rubber shock-absorbing core 3. The design of the guide assembly 4 can guide the bridge bearing to move smoothly in a predetermined direction when it is displaced by external force, effectively preventing the bearing from shifting.

[0022] Both the top support plate 1 and the bottom support plate 2 have mounting holes 13 on their surfaces. The design of the mounting holes 13 makes it easy to fix the bridge support between the superstructure and the substructure of the bridge using fasteners.

[0023] The rubber shock-absorbing core 3 mentioned above is an existing technology product, and its specific structure and function will not be described in detail here.

[0024] Working principle of this utility model: Refer to the instruction manual appendix Figure 1-5 When using this utility model, firstly, the support top plate 1 and support bottom plate 2 are installed on the bottom of the bridge and the top of the pier respectively through fasteners and mounting holes 13. Then, the dustproof sleeve 5, together with the upper ring plate 6 and the lower ring plate 7, is placed on the support bottom plate 2. Next, the rubber shock-absorbing core 3 is installed between the first limiting sleeve 8 and the second limiting sleeve 9. After that, multiple guide components 4 are installed one by one between the support top plate 1 and the support bottom plate 2 through screws, the first mounting plate 11 and the second mounting plate 12. Finally, the upper ring plate 6 and the lower ring plate 7 are installed on the bottom of the support top plate 1 and the top of the support bottom plate 2 respectively through screws. Thus, the installation of the bridge bearing is completed. When the external force on the bridge is transmitted to the bridge bearing, the rubber damping core 3 absorbs the vibration energy through elastic deformation. At the same time, the telescopic rod 10 of the guide component 4 extends and retracts, guiding the bridge bearing to move in a predetermined direction to prevent deviation. During this process, the dustproof sleeve 5 is sealed to the support top plate 1 and support bottom plate 2 through the upper ring plate 6 and the lower ring plate 7 respectively. Its rubber corrugated sleeve structure deforms synchronously with the extension and retraction of the bridge bearing, always wrapping the rubber damping core 3 and the guide component 4, preventing dust, sand and rainwater from entering the interior, and ensuring that the bridge bearing is in a stable working state for a long time.
