Description

Technical Field

[0001] The utility model relates to the technical field of friction pendulum bearings, in particular to a rubber reinforced friction pendulum bearing. Background Technique

[0002] ‌The rubber reinforced friction pendulum‌ is a seismic isolation technology that combines the characteristics of rubber seismic isolation bearings and friction pendulum seismic isolation bearings, aiming to provide more efficient seismic isolation effects. Through the movement of the spherical sliding surface, the superstructure undergoes a single pendulum movement. The period and stiffness of the seismic isolation system are controlled by selecting an appropriate curvature radius of the sliding surface, and the damping is controlled by the dynamic friction coefficient.

[0003] According to a rubber reinforced friction pendulum bearing disclosed in the publication number CN116289526A, the bearing is formed by connecting a friction pendulum bearing system and a rubber reinforcement system in parallel. The friction pendulum bearing system is stacked from top to bottom by an upper seat plate, a stainless steel upper sliding plate, a non-metallic upper sliding plate, a middle seat plate, a stainless steel lower sliding plate, a non-metallic lower sliding plate, and a lower seat plate. The rubber reinforcement system is composed of a rubber plate and a connecting steel plate.

[0004] For this rubber reinforced friction pendulum bearing, during the use of the device, although it overcomes the problem of relatively small secondary stiffness of the conventional friction pendulum bearing, it can effectively limit the seismic displacement of the bridge and improve the reset performance of the bridge after an earthquake. However, after using it for a period of time, the damping and buffering effect will be weakened. Therefore, the device needs to be improved. Content of the Utility Model

For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0026] The present utility model provides the following technical solutions:

[0027] Example 1, in combination with Figures 2 to 5 , a rubber-reinforced friction pendulum bearing, including an installation base 1, an installation mechanism 2 fixedly connected to the inner side wall of the installation base 1, and a clamping mechanism 3 fixedly connected to one end inside the installation base 1;

[0028] The installation mechanism 2 includes a buffer pad 21 fixedly connected to the inner side wall of the installation base 1. One end of the buffer pad 21 is fixedly connected to a bottom frame 22. The top end inside the bottom frame 22 is fixedly connected to a lower sliding plate 23. A slider 24 is arranged on the surface of the lower sliding plate 23. An upper sliding plate 25 is arranged on the surface of the slider 24. A sliding cover 26 is arranged on the surface of the upper sliding plate 25. The surface of the sliding cover 26 is fixedly connected to the top end of the inner wall of the installation base 1. Clamping seats 27 are respectively fixedly connected to the left and right sides of the sliding cover 26. A limiting plate 28 is fixedly connected to the side surface of the clamping seat 27. A first spring 29 is fixedly connected to the bottom end of the limiting plate 28. The bottom end of the first spring 29 is fixedly connected to the inside of the installation base 1. A limiting groove is opened inside the installation base 1. The surface of the limiting plate 28 is slidably connected to the inside of the limiting groove.

[0029] Furthermore, a cavity is opened inside the installation base 1. The surface of the upper sliding plate 25 is located inside the cavity. The shaking received by the installation base 1 drives the sliding cover 26 to shake inside the upper sliding plate 25 and the slider 24 inside the lower sliding plate 23. And at this time, the elastic acting force of the buffer pad 21 is used for corresponding support, and it plays a role in supporting and stabilizing the whole device. And when the sliding cover 26 shakes, it drives the clamping seat 27 to support and slide under the limitation of the limiting plate 28 inside the installation base 1, and plays a role in strengthening the support of the friction pendulum.

[0030] Example 2, refer to Figures 1-5 , and on the basis of Example 1, it is further obtained that the clamping mechanism 3 includes a second spring 31. One end of the second spring 31 is fixedly connected to a limiting block 32. A threaded rod 33 is fixedly connected to the inside of the limiting block 32. A threaded cylinder 34 is threadedly connected to the surface of the threaded rod 33. A rotating ring 35 is fixedly connected to one end of the surface of the threaded cylinder 34. An inclined clamping block 36 is fixedly connected to one end of the threaded rod 33. An inclined groove is opened inside one side of the clamping seat 27. The surface of the inclined clamping block 36 matches the inside of the inclined groove. A rectangular groove is opened in the middle inside the installation base 1. The surface of the limiting block 32 is slidably connected to the inside of the rectangular groove.

[0031] Furthermore, a round hole is opened on the front surface of the installation base 1. The surface of the threaded cylinder 34 is rotatably connected to the inside of the round hole. The threaded rod 33 moves inside the installation base 1, thereby driving the threaded rod 33 and the threaded cylinder 34 to move under the support of the second spring 31, and driving the inclined clamping block 36 to move. When the inclined clamping block 36 moves, the elastic support strength of the first spring 29 is changed by using the height between the inclined clamping block 36 and the clamping seat 27. Furthermore, the friction buffering acting force on the device can be effectively guaranteed, so that after using for a period of time, the damping and buffering effect can be continuously guaranteed.

[0032] During the actual operation process, when this device is in use, during the use of the friction pendulum bearing, the shaking received by the installation base 1 drives the sliding cover 26 to shake inside the upper sliding plate 25 and the slider 24 inside the lower sliding plate 23. At this time, the elastic force of the buffer pad 21 is used for corresponding support, and it plays a role in supporting and stabilizing the entire device. When the sliding cover 26 shakes, it drives the card seat 27 to support and slide under the limit of the limit plate 28 inside the installation base 1, and plays a role in strengthening the support for the friction pendulum;

[0033] In addition, when the buffering effect of the device weakens, at this time, rotating the rotating ring 35 drives the threaded cylinder 34 to rotate, and then drives the threaded rod 33 to move inside the installation base 1, thereby driving the threaded rod 33 and the threaded cylinder 34 to move under the support of the second spring 31. When the inclined block 36 moves, the elastic support strength of the first spring 29 is changed by the height between the inclined block 36 and the card seat 27, and thus the frictional buffering force of the device can be effectively guaranteed.

[0034] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.
