Description

Technical Field

[0001] This invention belongs to the field of seismic isolation bearing technology, specifically relating to a friction pendulum seismic isolation bearing with automatic reset function. Background Technology

[0002] Earthquakes are a terrible natural disaster that often damages buildings and other engineering facilities, and also causes serious casualties. In order to reduce the loss of life and property caused by earthquakes, it is necessary to strengthen and improve the seismic fortification capabilities of buildings.

[0003] Friction pendulum seismic isolation bearings are a type of friction-based seismic isolation bearing that has emerged in the field of building structure seismic isolation in recent years. Based on its concave geometry and surface friction characteristics, the friction pendulum allows the structure to slide on its concave surface during earthquakes and other vibrations, dissipating energy through friction. Under seismic loading, the isolation device absorbs seismic energy through significant deformation, providing a certain degree of damping to the structure. Simultaneously, the structural period increases, reducing the response of the superstructure.

[0004] However, existing friction pendulum seismic isolation bearings cannot be reset. In the event of natural disasters such as earthquakes, the friction pendulum seismic isolation bearings often need to be manually reset after they have moved to a certain extent. The reset operation is complicated and consumes a lot of manpower and resources. Therefore, how to provide a friction pendulum seismic isolation bearing with automatic reset function is a problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] The main objective of this invention is to provide a friction pendulum vibration isolation bearing with an automatic reset function to solve the aforementioned technical problems. The device includes a reset component and upper and lower sliding components capable of sliding in different directions, enabling the upper and lower sliding components to reset during use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A friction pendulum vibration isolation bearing with automatic reset function includes an upper sliding component, a lower sliding component, and a middle support plate. The upper sliding component is disposed at the top of the middle support plate, and the lower sliding component is disposed at the bottom of the middle support plate. The middle support plate is provided with multiple reset grooves, and sliding grooves are provided on both sides of the middle support plate. Each reset groove is provided with a reset component, and the upper and lower sliding components are reset through the reset components.

[0008] Furthermore, the upper sliding assembly includes an upper top plate and an upper top block. One side of the upper top plate is fixedly connected to one side of the upper top block. An upper groove is provided on the side of the upper top block away from the upper top plate. An upper slider is provided in the upper groove. The upper slider is slidably connected to the central support plate through the upper groove and the upper groove.

[0009] Furthermore, the sliding assembly includes a lower top plate and a lower top block. One side of the lower top plate is fixedly connected to one side of the lower top block. A lower groove is provided on the side of the lower top block away from the lower top plate. A lower slider is provided in the lower groove. The lower slider is slidably connected to the central support plate through the lower groove and the lower groove.

[0010] Furthermore, both the upper and lower grooves are arc-shaped grooves, and the directions of the upper and lower grooves are perpendicular to each other. Both the upper and lower sliders are cylindrical sliders.

[0011] Furthermore, both the upper and lower grooves are circular arc grooves, and both the upper and lower sliders are ellipsoidal sliders.

[0012] Furthermore, the reset assembly includes a guide rod, a spring, and a reset assembly plate. The reset assembly plate is provided with multiple guide holes. One end of the guide rod is fixed to the inner wall of the reset groove, and the other end of the guide rod passes through the guide hole of the reset assembly plate and is fixed to the inner wall of the opposite side of the reset groove. A spring is sleeved on the guide rod. One end of the spring is connected to one side of the reset assembly plate, and the other end of the spring abuts against the inner wall of the reset groove.

[0013] Furthermore, the reset assembly plate includes a first reset plate and a second reset plate. Both the first reset plate and the second reset plate are provided with connecting holes, which are used to fix the first reset plate and the second reset plate. Both the first reset plate and the second reset plate are provided with multiple guide holes, which are used to connect the first reset plate and the second reset plate to the guide rod.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention is equipped with a reset component and upper and lower sliding components that can slide in different directions. During use, the upper and lower sliding components can be reset. At the same time, when the upper and lower sliders are ellipsoidal sliders, the sliding of the upper and lower sliding components will cause compression of the reset combination plates on the upper and lower sides of the central support plate. Multiple reset components will share the pressure, making the overall bearing capacity of the seismic isolation support stronger and the reset effect better. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1:

[0030] like Figures 1-8As shown, the present invention provides a friction pendulum vibration isolation support with automatic reset function, including an upper sliding component, a lower sliding component, and a middle support plate 2. The upper sliding component is disposed at the top of the middle support plate 2, and the lower sliding component is disposed at the bottom of the middle support plate 2. The middle support plate 2 is provided with a plurality of reset grooves 9, and sliding grooves 12 are provided on both sides of the middle support plate 2. Each reset groove 9 is provided with a reset component 6. The reset components 6 are used to reset the upper sliding component and the lower sliding component. When the upper sliding component and the lower sliding component slide, they can cooperate with the reset component 6 to reset.

[0031] In this embodiment, the upper sliding assembly includes an upper top plate 1 and an upper top block 4. One side of the upper top plate 1 is fixedly connected to one side of the upper top block 4. An upper groove is provided on the side of the upper top block 4 away from the upper top plate 1. An upper slider 7 is provided in the upper groove. The upper slider 7 is slidably connected to the middle support plate 2 through the upper groove and the upper slider 7.

[0032] In this embodiment, the sliding component includes a lower top plate 3 and a lower top block 5. One side of the lower top plate 3 is fixedly connected to one side of the lower top block 5. A lower groove is provided on the side of the lower top block 5 away from the lower top plate 3. A lower slider 8 is provided in the lower groove. The lower slider 8 is slidably connected to the central support plate 2 through the lower groove and the lower groove.

[0033] In this embodiment, both the upper and lower grooves are arc-shaped grooves, and the directions of the upper and lower grooves are perpendicular to each other. Both the upper slider 7 and the lower slider 8 are cylindrical sliders. The cylindrical sliders can realize the sliding of the upper sliding component and the lower sliding component, and the perpendicularity of the directions of the upper and lower grooves can avoid mutual interference.

[0034] In this embodiment, the reset assembly 6 includes a guide rod 10, a spring 11, and a reset assembly plate. The reset assembly plate is provided with a plurality of guide holes 15. One end of the guide rod 10 is fixed to the inner wall of the reset groove 9, and the other end of the guide rod 10 passes through the guide hole 15 of the reset assembly plate and is fixed to the inner wall of the opposite side of the reset groove 9. The spring 11 is sleeved on the guide rod 10. One end of the spring 11 is connected to one side of the reset assembly plate, and the other end of the spring 11 abuts against the inner wall of the reset groove 9. When the reset assembly plate is compressed, it moves along the guide rod 10, and at the same time, it compresses or pulls the spring 11. The compression force of the spring is used to reset the upper sliding assembly and the lower sliding assembly.

[0035] In this embodiment, the reset assembly plate includes a first reset plate 13 and a second reset plate 14. Both the first reset plate 13 and the second reset plate 14 are provided with connecting holes, which are used to fix the first reset plate 13 and the second reset plate 14. Both the first reset plate 13 and the second reset plate 14 are provided with a plurality of guide holes 15, which are connected to the guide rod 10 through the guide holes 15. Both the first reset plate 13 and the second reset plate 14 are T-shaped plates, which makes it easier to disassemble and replace the first reset plate 13 and the second reset plate 14, avoiding the situation where one end is damaged and the entire component needs to be replaced.

[0036] Working principle: When in use, the upper sliding component slides due to the influence of the external environment. When the upper sliding component moves, the upper top block 4 pushes the reset assembly plate to move, causing the spring 11 to be squeezed. When the influence of the external environment decreases, the upper sliding component resets under the squeezing force of the spring 11. The upper sliding component can only move in the left and right directions, while the lower sliding rod component can only move in the forward and backward directions.

[0037] Example 2:

[0038] refer to Figures 9-10 As shown, the only difference between this embodiment and Embodiment 1 is that both the upper and lower grooves are arc grooves, and both the upper slider 7 and the lower slider 8 are ellipsoidal sliders. The ellipsoidal sliders allow the sliding direction of the upper and lower sliding components to be unrestricted. When the upper sliding component slides, it presses against the reset assembly plate at the top of the central support plate 2, simultaneously causing the central support plate 2 to move. At this time, the lower top block 5 in the lower sliding component does not move, but instead presses against the reset assembly plate at the bottom of the central support plate 2, resulting in a stronger overall bearing capacity of the seismic isolation bearing.

[0039] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.

[0040] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
