Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of friction pendulum vibration isolation bearings, and in particular to a high-performance friction pendulum vibration isolation bearing. Background Technology
[0002] Chinese patent document CN221052861U discloses a high-performance friction pendulum seismic isolation bearing structure, which includes the following steps: First, spherical grooves are symmetrically machined on the upper and lower surfaces of a spherical cap liner. Then, a non-metallic sliding panel is fabricated and installed to fit the spherical groove. Next, grooves are machined on the inner surfaces of the upper and lower bearing plates, and a metal sliding panel is inlaid. The design of the braking groove and inclined groove on the spherical cap liner enhances the connection stability between the non-metallic sliding panel and the spherical cap liner. The bearing plate adopts a pressure plate to fix the metal sliding panel structure, which can improve the defects caused by using screw fixation. These structures and steps together achieve a high-performance seismic isolation effect, with high reliability, stability and durability. When the building undergoes horizontal displacement under earthquake or external force, the movement of the friction pendulum seismic isolation bearing absorbs and slows down energy transfer, thereby protecting the structure and reducing the impact of vibration on the building.
[0003] After investigation and analysis, the patent has the following drawbacks in actual use:
[0004] When this device is used, it is mostly installed using bolts and nuts. However, bolts and nuts cannot store or release energy, resulting in high wear on the support and further reducing its service life.
[0005] In summary, this application proposes a high-performance friction pendulum isolation bearing to solve the aforementioned problems. Utility Model Content
[0006] The purpose of this utility model is to provide a high-performance friction pendulum vibration isolation support, which can solve the problem that when this device is used, it is mostly installed by bolts and nuts. When bolts and nuts are used, they cannot play the role of storing and releasing energy, resulting in a high wear rate of the support and further reducing its service life.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-performance friction pendulum vibration isolation bearing, comprising an upper support plate and a buffer assembly, wherein a lower support plate is disposed on the upper support plate, and the buffer assembly is located on the upper support plate and the lower support plate. The buffer assembly comprises a crossbar, a movable plate, a sleeve, a connecting rod, a damper, a spring, and bolts. The crossbars are arranged in four groups in a circular array, and movable plates are fixedly connected to both ends of the crossbars. Sleeves are fixedly connected to the opposite sides of the upper support plate and the lower support plate.
[0008] Preferably, both the upper support plate and the lower support plate have openings, which facilitates the installation of the buffer assembly.
[0009] Preferably, a lower mounting base is fixedly connected to the top of the lower support plate, and a ball head is fixedly connected to the top of the lower mounting base, which facilitates the upper support plate to swing.
[0010] Preferably, the bottom of the upper support plate is fixedly connected to an upper mounting base, and the bottom of the upper mounting base is provided with a hemispherical groove, and the top of the ball head is rotatably installed in the hemispherical groove on the upper mounting base.
[0011] Preferably, a connecting rod is fixedly connected to the sleeve, and a bolt is provided on the connecting rod. A damper and a spring are fixedly connected to the inner wall of one side of the sleeve. The spring is sleeved and installed on the outer wall of the damper. One end of the damper and the spring is connected to the moving plate. Through the coordinated use of the crossbar, the moving plate, the sleeve, the connecting rod, the damper, the spring, and the bolt, the upper support plate and the lower support plate can be buffered. This helps reduce the amplitude of structural vibration and prevents the support from excessive offset or displacement, thereby ensuring the long-term stability of the support. Compared with traditional supports, the spring and damper are more effective during long-term use.
[0012] Preferably, one end of each connecting rod passes through the openings in the upper and lower support plates, and a bolt is threaded onto the outer wall of one end of the connecting rod, which facilitates the fixing of the buffer assembly.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-performance friction pendulum vibration isolation bearing, through the coordinated use of crossbars, moving plates, sleeves, connecting rods, dampers, springs, and bolts, can buffer the use of the upper and lower support plates, helping to reduce the amplitude of structural vibration and prevent excessive offset or displacement of the bearing, thereby ensuring the long-term stability of the bearing. Compared with traditional bearings, during long-term use, the springs and dampers can effectively share part of the load, reduce the wear rate of the bearing, and thus extend the service life of the bearing.

[0020] Please see Figure 1-3This utility model provides a technical solution: a high-performance friction pendulum vibration isolation bearing, including an upper support plate 1 and a buffer assembly. A lower support plate 2 is provided on the upper support plate 1. Both the upper support plate 1 and the lower support plate 2 have openings to facilitate the installation of the buffer assembly. A lower mounting seat 3 is fixedly connected to the top of the lower support plate 2, and a ball head 4 is fixedly connected to the top of the lower mounting seat 3 to facilitate the swinging motion of the upper support plate 1. An upper mounting seat 5 is fixedly connected to the bottom of the upper support plate 1. A hemispherical groove is provided at the bottom of the upper mounting seat 5, and the top of the ball head 4 is rotatably mounted on the upper support plate 1. The buffer assembly is located in the hemispherical groove on the mounting base 5, on the upper support plate 1 and the lower support plate 2. The buffer assembly includes a crossbar 6, a movable plate 7, a sleeve 8, a connecting rod 9, a damper 10, a spring 11, and bolts 12. The crossbar 6 consists of four groups arranged in a circular array. The movable plate 7 is fixedly connected to both ends of the crossbar 6. The sleeve 8 is fixedly connected to the opposite sides of the upper support plate 1 and the lower support plate 2. The connecting rod 9 is fixedly connected to the sleeve 8, and bolts 12 are installed on the connecting rod 9.

Then, the sleeve 8 is manually squeezed, causing the damper 10 and the spring 11 inside the sleeve 8 to move. When the sleeve 8 moves, it drives the connecting rod 9 to move. The connecting rod 9 is then passed through the openings on the upper support plate 1 and the lower support plate 2. The bolt 12 is then threaded onto the outer wall of the connecting rod 9. Through the combined use of the crossbar 6, the moving plate 7, the sleeve 8, the connecting rod 9, the damper 10, the spring 11, and the bolt 12, the upper support plate 1 and the lower support plate 2 can be buffered, reducing the amplitude of structural vibration and preventing excessive offset or displacement of the support, thus ensuring the long-term stability of the support. Compared with traditional supports, the spring and damper contribute significantly to this stability during long-term use.
[0021] Working principle: When in use, lift up the upper support plate 1, which is located above the lower support plate 2. Then lift up the crossbar 6 and place it between the upper support plate 1 and the lower support plate 2. Then manually squeeze the sleeve 8 to move the damper 10 and spring 11 inside the sleeve 8. When the sleeve 8 moves, it drives the connecting rod 9 to move. Then pass the connecting rod 9 through the openings on the upper support plate 1 and the lower support plate 2. Then thread the bolt 12 onto the outer wall of the connecting rod 9.
