Description

Technical Field

[0001] This utility model relates to the field of tensile technology, specifically to a tensile-pull-out friction pendulum vibration isolation support. Background Technology

[0002] Tensile strength generally refers to the ability of a substance or material to resist or withstand tensile forces. Specifically, tensile strength is the maximum stress a material can withstand during tension, and it is commonly used to measure a material's durability and strength.

[0003] A friction pendulum seismic isolation bearing (publication number: CN113323480A) disclosed in the public notice includes an upper bearing plate, a lower bearing plate, a pressure cap, and a spherical crown. The spherical crown is located between the upper and lower bearing plates. There are two pressure caps, one located above each end of the lower bearing plate. One end of the pressure cap is fixedly connected to the end of the lower bearing plate, and the other end is connected and positioned to the upper bearing plate via a positioning pin. The two ends of the pressure cap respectively form limiting contacts for the horizontal and vertical movement of the upper bearing plate. In the free state, the upper bearing plate rotates relative to the spherical crown, and the spherical crown slides along the spherical surface of the lower bearing plate. The positioning pin positions the upper bearing plate at the center position. This friction pendulum seismic isolation bearing not only possesses the good performance of ordinary friction pendulum bearings, but also provides vertical pull-out resistance. When horizontal displacement exceeding the structural design occurs, it can also provide horizontal restraint force to prevent the bearing from falling off.

[0004] The aforementioned patent achieves the effect of providing horizontal constraint force and preventing the support from falling off by cooperating with components such as the upper seat plate and the lower seat plate. However, it cannot achieve a better tensile effect. Therefore, we propose a tensile-pull-out friction pendulum seismic isolation support. Utility Model Content

[0005] To overcome the above-mentioned defects, this utility model provides an anti-pull-out friction pendulum vibration isolation support, which solves the technical problem that the existing technology cannot achieve better tensile resistance.

[0006] According to one aspect, at least one embodiment of the present invention provides a pull-out friction pendulum vibration isolation support, comprising: an upper anchor fixing device, one end of the upper anchor fixing device being connected to an upper support plate, and a tension-resistant device being provided between the upper support plate and the lower support plate;

[0007] The tensile device includes a groove formed on the upper and lower support plates. A dumbbell-shaped crown-shaped liner is slidably connected to the inner side of the groove. Slide plates are located at both ends of the dumbbell-shaped crown-shaped liner. A stainless steel plate is fixedly connected to the bottom inner side of the groove. Through the interaction of these components, this tensile device provides a stable, durable structure with high tensile strength, ensuring that the connected components remain stable, slide smoothly, and possess a certain load-bearing capacity during operation.

[0008] For example, in at least one embodiment of this utility model, an anti-pull-out friction pendulum seismic isolation bearing further includes: an arc-shaped cover plate fixedly connected to the bottom of the upper support plate, and a lower support plate slidably connected to one end of the dumbbell-shaped crown-shaped liner. The arc-shaped cover plate is mainly responsible for protecting and increasing the stability of the structure, while the lower support plate provides support and adjusts the relative position of the device through a sliding connection, and enhances the load-bearing capacity and flexibility of the tensile device.

[0009] The bottom of the lower support plate is fixedly connected to a lower anchor fixing device, and four or eight lower anchor fixing devices are provided. The function of the lower anchor fixing device is to ensure that the entire structure is firmly fixed, and the lower anchor fixing device increases the stability of the device by distributing the fixing points, thereby enhancing the overall safety and reliability of the tensile device.

[0010] The lower anchor fixing device is symmetrical about the longitudinal axis of the lower support plate, and four or eight upper anchor fixing devices are provided. By setting multiple symmetrical anchor fixing devices in the upper and lower parts respectively, it can be ensured that the external force can be distributed more evenly and stably when the entire structure is under stress, thereby improving the safety, stability and durability of the structure. The lower anchor fixing device provides better ground fixation, while the upper anchor fixing device enhances the stability and tensile strength of the upper part, ensuring that the entire device is in a balanced and stable state during operation.

[0011] The upper anchor fixing device is symmetrical about the longitudinal axis of the upper support plate, and two grooves are provided, one corresponding to the upper support plate and the other to the lower support plate. The symmetrical arrangement of the anchor fixing device ensures the uniform distribution of force on the device, enhancing the stability and deformation resistance of the structure.

[0012] Two stainless steel plates are provided, each corresponding to the upper support plate and the lower support plate, respectively. This correspondence between the stainless steel plates and the upper and lower support plates ensures precise alignment of the device during operation, improving overall stability and stress balance.

[0013] Two sliding plates are provided, each positioned at one end of the dumbbell-shaped crown-shaped liner. The dumbbell-shaped crown-shaped liner, as a key component for support and load distribution, works in conjunction with the sliding plates to further enhance the system's stability, shock absorption, and overall stability.

[0014] According to another aspect, at least one embodiment of this utility model also provides an anti-pull-out friction pendulum vibration isolation support, comprising: a dustproof device provided on the circumferential surface of the dumbbell-shaped crown-shaped liner, the dustproof device including a dustproof sleeve, the dustproof sleeve being slidably connected to the circumferential surface of the dumbbell-shaped crown-shaped liner, a connecting strap being fixedly connected to one end of the dustproof sleeve, a hook surface being fixedly connected to the bottom of the connecting strap, and a ring surface being fixedly connected to the top of the dustproof sleeve. The ring surface fixedly connected to the top of the dustproof sleeve mainly serves to further enhance the sealing performance of the dustproof sleeve. Through contact with other components of the equipment, the ring surface can effectively seal the top of the dustproof sleeve, preventing dust or other contaminants from entering the interior of the equipment.

[0015] For example, in at least one embodiment of this utility model, an anti-pull-out friction pendulum vibration isolation support further includes: the diameter of the dust cover is larger than the diameter of the groove, and the bottom of the dust cover is slidably connected to the top of the arc-shaped cover plate. The larger diameter of the dust cover ensures that it effectively covers the groove, preventing external contaminants from entering.

[0016] Two dust covers are provided, each corresponding to one of the two arc-shaped cover plates. The two dust covers provide stronger dust protection, ensuring the equipment is not contaminated by external sources during operation.

[0017] The beneficial effects of the embodiments of this utility model are as follows:

[0018] 1. In this utility model, the dumbbell-shaped crown-shaped liner is achieved through the cooperation of components such as the upper support plate, the lower support plate, and the groove. The operator places the dumbbell-shaped crown-shaped liner into the groove. When the upper and lower anchoring devices are simultaneously subjected to tensile and shear forces, the dumbbell-shaped crown-shaped liner slides within the groove via a sliding plate. Simultaneously, the arc-shaped cover plate restricts the movement range of the dumbbell-shaped crown-shaped liner while providing a certain tensile strength. This results in a stable, durable structure with high tensile strength, ensuring that the connected components remain stable, slide smoothly, and possess a certain load-bearing capacity during operation.

[0019] 2. In this utility model, dust prevention is achieved through the cooperation of components such as a dust cover, connecting strap, and hook face. The operator places the dust cover on the circumference of the dumbbell-shaped crown liner, presses the connecting strap, and aligns the hook face on the connecting strap with the circumference, causing them to adhere. Thus, when the dumbbell-shaped crown liner moves, it moves the dust cover along the surface of the arc-shaped cover, preventing external dust and dirt from entering the groove and damaging the internal components. This effectively seals the top of the dust cover, preventing dust or other contaminants from entering the equipment. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit its scope.

[0028] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] like Figures 1-5 As shown, it illustrates a pull-out friction pendulum vibration isolation support according to an embodiment of the present invention, including an upper anchor fixing device 1, one end of which is connected to an upper support plate 2, and an anti-tension device 3 is provided between the upper support plate 2 and the lower support plate 36.

[0034] The tensile device 3 includes a groove 31 formed on the upper support plate 2 and the lower support plate 36. A dumbbell-shaped crown-shaped liner 32 is slidably connected to the inner side of the groove 31. Slide plates 33 are connected to both ends of the dumbbell-shaped crown-shaped liner 32. A stainless steel plate 34 is fixedly connected to the bottom inner side of the groove 31. Through the interaction of these components, this tensile device 3 provides a stable, durable structure with high tensile strength, ensuring that the connected components remain stable, slide smoothly, and have a certain load-bearing capacity during operation.

[0035] In some examples, an arc-shaped cover plate 35 is fixedly connected to the bottom of the upper support plate 2, and a lower support plate 36 is slidably connected to one end of the dumbbell-shaped crown-shaped liner 32. The arc-shaped cover plate 35 is mainly responsible for protecting and increasing the stability of the structure, while the lower support plate 36 provides support and adjusts the relative position of the device through a sliding connection, and enhances the load-bearing capacity and flexibility of the tensile device 3.

[0036] The bottom of the lower support plate 36 is fixedly connected to a lower anchor fixing device 37, and four or eight lower anchor fixing devices 37 are provided. The function of the lower anchor fixing device 37 is to ensure that the entire structure is firmly fixed, and the lower anchor fixing device 37 increases the stability of the device by distributing the fixing points, thereby enhancing the overall safety and reliability of the tensile device 3.

[0037] The lower anchor fixing device 37 is symmetrical about the longitudinal axis of the lower support plate 36, and the upper anchor fixing device 1 has four or eight components. By symmetrically setting multiple anchor fixing devices in the upper and lower parts, it can be ensured that the external force can be distributed more evenly and stably when the entire structure is under stress, thereby improving the safety, stability and durability of the structure. The lower anchor fixing device 37 provides better ground fixation, while the upper anchor fixing device 1 enhances the stability and tensile strength of the upper part, ensuring that the entire device is in a balanced and stable state during operation.

[0038] The upper anchor fixing device 1 is symmetrical about the longitudinal axis of the upper support plate 2, and two grooves 31 are provided, which correspond to the upper support plate 2 and the lower support plate 36 respectively. The symmetrical arrangement of the upper anchor fixing device 1 ensures the uniform distribution of force on the device and enhances the stability and deformation resistance of the structure.

[0039] Two stainless steel plates 34 are provided, corresponding to the upper support plate 2 and the lower support plate 36 respectively. The corresponding design of the stainless steel plates 34 with the upper support plate 2 and the lower support plate 36 ensures precise docking of the device during operation, improving the overall stability and stress balance.

[0040] Two slide plates 33 are provided, one at each end of the dumbbell-shaped crown bushing 32. The dumbbell-shaped crown bushing 32, as a key component for support and load distribution, works in conjunction with the slide plates 33 to further improve the system's stability, shock absorption, and overall stability.

[0041] For example, as shown in the figure, the operator accurately places the dumbbell-shaped crown liner 32 into the groove 31 and ensures its position is fixed. When the upper anchoring device 1 and the lower anchoring device 37 are simultaneously subjected to tension and shear forces, the dumbbell-shaped crown liner 32 will slide smoothly within the groove 31 along with the sliding plate 33, allowing it to move freely within a certain range. At the same time, the arc-shaped cover plate 35, through its unique structural design, limits the range of movement of the dumbbell-shaped crown liner 32, preventing it from sliding excessively and causing unnecessary damage or displacement. In addition, the stainless steel plate 34 embedded in the system plays an important role, providing sliding force support, effectively enhancing the stability and durability of the overall device, ensuring that the dumbbell-shaped crown liner 32 can remain stable under high load or harsh working conditions, avoiding damage or structural failure due to excessive tension.

[0042] like Figures 1-5 As shown, this is another embodiment of the anti-pull-out friction pendulum vibration isolation support of the present invention, including a dustproof device 4 provided on the circumferential surface of a dumbbell-shaped crown-shaped liner 32. The dustproof device 4 includes a dustproof sleeve 41, which is slidably connected to the circumferential surface of the dumbbell-shaped crown-shaped liner 32. A connecting strap 42 is fixedly connected to one end of the dustproof sleeve 41, a hook surface 43 is fixedly connected to the bottom of the connecting strap 42, and a ring surface 44 is fixedly connected to the top of the dustproof sleeve 41. The ring surface 44, fixedly connected to the top of the dustproof sleeve 41, mainly enhances the sealing performance of the dustproof sleeve 41. Through contact with other components of the equipment, the ring surface 44 can effectively seal the top of the dustproof sleeve 41, preventing dust or other contaminants from entering the equipment.

[0043] In some examples, the diameter of the dust cover 41 is larger than the diameter of the groove 31, and the bottom of the dust cover 41 is slidably connected to the top of the arc-shaped cover plate 35. The larger diameter of the dust cover 41 ensures that the dust cover 41 can effectively cover the groove 31, preventing external contaminants from entering.

[0044] Two dust covers 41 are provided, each corresponding to one of the two arc-shaped cover plates 35. The two dust covers 41 provide stronger dust protection, ensuring that the equipment is not contaminated by external sources during operation.

[0045] For example, such as Figure 1 As shown, the operator places the dust cover 41 on the circumferential surface of the dumbbell-shaped crown liner 32, presses the connecting strap 42, aligns the hook surface 43 on the connecting strap 42 with the ring surface 44, and makes them stick together. Thus, when the dumbbell-shaped crown liner 32 moves, the dumbbell-shaped crown liner 32 drives the dust cover 41 to move on the surface of the arc-shaped cover plate 35, preventing external dust and dirt from entering the groove 31 and damaging the internal components.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
