Description

Technical Field

[0001] The utility model relates to the technical field of shock-absorbing bearings, in particular to a bridge shock-absorbing bearing. Background Technique

[0002] The bridge shock-absorbing bearing is an important part of the bridge structure. Its main function is to reduce the vibration of the bridge under the action of external forces such as earthquakes and winds, thereby protecting the bridge structure from damage. The design and selection of shock-absorbing bearings are crucial for ensuring the safety and stability of the bridge.

[0003] Such bridge shock-absorbing bearings in the prior art are diverse, including rubber shock-absorbing bearings, steel shock-absorbing bearings, etc. However, for such rubber shock-absorbing bearings in the prior art, generally, based on the elasticity of the rubber itself, it can play a good buffering role for the vibration in the vertical direction. However, the vibration direction may come from all directions, so it cannot play a good buffering effect on the vibration from the front, back, left, and right. Therefore, an improved bridge shock-absorbing bearing is needed to solve this problem. Content of the Utility Model

[0004] The purpose of the utility model is to provide a bridge shock-absorbing bearing to solve the problems put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a bridge shock-absorbing bearing, including a bottom plate, a top plate is arranged at the upper end of the bottom plate, a shock-absorbing mechanism is arranged between the bottom plate and the top plate, the shock-absorbing mechanism includes a fixed bin, an arc-shaped slope, a rubber shock-absorbing bearing, an arc-shaped bottom surface, a mounting column, and a leaf spring. A fixed bin is fixedly arranged at the upper end of the bottom plate, an arc-shaped slope is arranged at the lower end inside the fixed bin, a rubber shock-absorbing bearing is fixedly arranged at the lower end of the top plate, an arc-shaped bottom surface is fixedly arranged at the lower end of the rubber shock-absorbing bearing, mounting columns are fixedly arranged at the four corners inside the fixed bin, and leaf springs are snap-fitted on the outer surface of the mounting columns.

[0006] Preferably, a fixed frame is fixedly arranged on the outer surface of the leaf spring. Through the fixed frame, multiple leaf springs can be connected together to improve the elasticity of the leaf spring.

[0007] Preferably, viscous damping oil is arranged inside the fixed bin; through the viscous damping oil, when the arc-shaped bottom surface moves back and forth and left and right inside the fixed bin due to vibration, friction occurs between it and the viscous damping oil; thereby, the vibration kinetic energy in the front, back, left, and right directions can be converted into heat energy generated by friction with the viscous damping oil; thus, it plays a role in shock absorption and buffering of the bridge.

[0008] Preferably, through holes are arranged on the outer surface of the arc-shaped bottom surface. Through the through holes, the contact area between the arc-shaped bottom surface and the viscous damping oil can be significantly increased, thereby improving the friction energy dissipation effect.

[0009] Preferably, a rubber sealing layer is fixedly arranged between the rubber shock absorber and the fixed bin; through the rubber sealing layer, the upper end of the fixed bin can be sealed, preventing the leakage of the viscous damping oil inside the fixed bin. At the same time, due to its own elasticity, it can deform, so it will not hinder the front-back and left-right sliding of the rubber shock absorber and the arc-shaped bottom surface inside the fixed bin.

[0010] Preferably, mounting holes are provided at the four corners of the outer surfaces of the bottom plate and the top plate. Through the mounting holes, it is convenient to fixedly install the bottom plate at the target position of the bridge pier and at the same time install the top plate at the target position of the bridge body; finally, the device can be installed between the bridge pier and the bridge body.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. Once vibrations occur in the front-back, left-right directions in the present utility model, it will cause the rubber shock absorber and the arc-shaped bottom surface to move in the corresponding directions inside the functional bin; when the arc-shaped bottom surface moves, it will squeeze the leaf spring, causing the leaf spring to deform and accumulate elastic potential energy; and at this time, when the arc-shaped bottom surface moves back and forth and left and right inside the fixed bin, friction will occur with the viscous damping oil; thus, the vibration kinetic energy in the front-back and left-right directions can be converted into heat energy generated by friction with the viscous damping oil; then when the leaf spring pushes the arc-shaped bottom surface to reset, friction will continue to occur; in this way, it plays a role in shock absorption and buffering of the bridge, based on the front-back and left-right shaking space of the rubber shock absorber, and can consume the vibration energy during shaking; thus, the shock absorption and buffering effect of the device on the bridge can be greatly improved.

[0013] 2. When the present utility model is in use, the arc-shaped bottom surface contacts the arc-shaped slope. The purpose is that since the weight of each section of the bridge is very heavy, after the rubber shock absorber moves left or right, or back and forth, relying solely on the self-elastic force of the leaf spring may not be able to help the bridge reset. At this time, by using the downward sliding force generated by the arc-shaped slope and the self-gravity of the bridge, it can ensure that the rubber shock absorber and the arc-shaped bottom surface can reset after each vibration; thus, the use effect of the device can be improved.

[0022] Viscous damping oil is arranged inside the fixed chamber 3; through the viscous damping oil, when the arc-shaped bottom surface 6 moves back and forth and left and right inside the fixed chamber 3 due to vibration, friction occurs between the arc-shaped bottom surface 6 and the viscous damping oil; thus, the vibration kinetic energy in the front-back and left-right directions can be converted into heat energy generated by friction with the viscous damping oil; in this way, the shock-absorbing and buffering effect of the bridge is achieved;

[0023] Through holes 9 are opened on the outer surface of the arc-shaped bottom surface 6, and the contact area between the arc-shaped bottom surface 6 and the viscous damping oil can be significantly increased through the through holes 9, so as to improve the friction energy dissipation effect;

[0024] A rubber sealing layer 10 is fixedly arranged between the rubber shock absorber bearing 5 and the fixed bin 3; through the rubber sealing layer 10, the upper end of the fixed bin 3 can be sealed, preventing the leakage of the viscous damping oil inside the fixed bin 3. At the same time, due to its own elasticity, it can deform, so it will not hinder the front-back and left-right sliding of the rubber shock absorber bearing 5 and the arc-shaped bottom surface 6 inside the fixed bin 3;

[0025] Mounting holes 11 are provided at the four corners of the outer surfaces of the bottom plate 1 and the top plate 2. Through the mounting holes, it is convenient to fixedly install the bottom plate 1 at the target position of the bridge pier, and at the same time, it is convenient to install the top plate 2 at the target position of the bridge body; finally, the device can be installed between the bridge pier and the bridge body.

[0026] Working principle: When using this device, through the mounting holes 11, it is convenient to fixedly install the bottom plate 1 at the target position of the bridge pier, and at the same time, it is convenient to install the top plate 2 at the target position of the bridge body; finally, the device can be installed between the bridge pier and the bridge body; then when the device is in use, the rubber shock absorber bearing 5 can be compressed due to its own elasticity, so as to achieve a certain buffering and shock-absorbing effect in the vertical plane; and once vibrations occur in the front-back, left-right directions, it will cause the rubber shock absorber bearing 5 and the arc-shaped bottom surface 6 to move in the corresponding directions inside the functional bin; when the arc-shaped bottom surface 6 moves, it will squeeze the leaf spring 8, causing the leaf spring 8 to deform and accumulate elastic potential energy; and at this time, when the arc-shaped bottom surface 6 moves back and forth and left and right inside the fixed bin 3 due to vibrations, it will rub against the viscous damping oil; thus, the vibration kinetic energy in the front-back and left-right directions can be converted into heat energy generated by rubbing against the viscous damping oil; then when the leaf spring 8 pushes the arc-shaped bottom surface 6 to reset, it will continue to generate friction; in this way, it plays a role in buffering and shock-absorbing the bridge, based on the front-back and left-right swaying space of the rubber shock absorber bearing 5, and the energy of vibrations can be consumed when swaying; thus, the buffering and shock-absorbing effect of this device on the bridge can be greatly improved; and when this device is in use, the arc-shaped bottom surface 6 contacts the arc-shaped slope 4. The purpose is that since the weight of each section of the bridge is very heavy, after the rubber shock absorber bearing 5 moves left or right, or back and forth, relying solely on the self-elastic force of the leaf spring 8 may not be able to help the bridge reset. At this time, using the downward sliding force generated by the arc-shaped slope 4 and the self-gravity of the bridge can ensure that the rubber shock absorber bearing 5 and the arc-shaped bottom surface 6 can be reset after each vibration; thus, the use effect of this device can be improved.
