Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, and in particular to a rotatable, self-adjusting, pull-out friction-resistant pendulum support. Background Technology
[0002] In the field of building engineering, structural stability and seismic performance are of paramount importance. With the continuous development of building technology and the increasing demands for building safety, bearings, as key components connecting the building structure and foundation, directly affect the stability and safety of the entire building. Existing bearings, due to environmental factors (such as moisture and corrosion), will gradually decline in performance over long-term use, leading to a shortened service life and increased maintenance costs and safety risks. Utility Model Content
[0003] This utility model aims to at least partially solve one of the technical problems in the related art.
[0004] Therefore, the purpose of this utility model is to propose a rotatable, self-adjusting, anti-pull-out friction pendulum support, which can solve the problem that the performance of the vibration isolation gradually declines due to the influence of environmental factors (such as humidity, corrosion, etc.).
[0005] To achieve the above objectives, this utility model proposes a rotatable, self-adjusting, anti-pull-out friction pendulum support, comprising a lower seismic isolation support and an upper seismic isolation support. The lower and upper seismic isolation supports are each rotatably connected to a central rotating plate. A double-spherical liner is slidably connected between the two central rotating plates. Wear-resistant rotating plates are installed at both ends of the double-spherical liner. Annular clamping plates are installed on the outer walls of the two central rotating plates. Two fixed semi-annular plates are provided between the two annular clamping plates. Upper sealing ring plates are engaged at both ends of the two fixed semi-annular plates. One end of the upper sealing ring plate is in contact with the annular clamping plate. A limiting arc-shaped rod is fixedly connected to the annular clamping plate. An arc-shaped clamping plate is slidably connected to the inner wall of the limiting arc-shaped rod, and the outer wall of the arc-shaped clamping plate is in contact with the inner wall of the limiting arc-shaped rod.
[0006] This utility model's rotatable, self-adjusting, pull-out friction pendulum support, through a sealing assembly composed of a fixed semi-ring plate, an upper sealing ring plate, a lower sealing ring plate, an annular clamping plate, and a limiting arc rod, effectively reduces the entry of impurities and water between the central rotating plates. It also prevents rust and other adverse effects on the connection between the double spherical liner and the wear-resistant rotating plate and the central rotating plate, thereby extending the support's service life, reducing maintenance costs, and improving the long-term stability of the building structure. Furthermore, the cooperation of components such as slots, mounting grooves, sliding columns, and springs allows the upper and lower sealing ring plates to be easily separated from and replaced by the fixed semi-ring plate, facilitating the repair and replacement of damaged parts during support use, further improving the support's maintainability.
[0007] In addition, the rotatable self-adjusting anti-pull-out friction pendulum support proposed above according to this utility model may also have the following additional technical features:
[0008] Specifically, both the lower and upper seismic isolation supports are provided with several connection holes, and a support plate that fits against one end of the lower and upper seismic isolation supports is fixedly connected to one end of the central rotating plate.
[0009] Specifically, the top of the lower seismic isolation bearing is fixedly connected to four equally spaced fixing frames, one end of which is connected to the outer wall of the fixed semi-ring plate.
[0010] Specifically, the upper sealing ring plate and the lower sealing ring plate are provided with a slot at the connection with the fixed half ring plate, and the fixed half ring plate is provided with an installation groove corresponding to the slot. A sliding column is slidably connected to the inner wall of the installation groove, and the sliding column is connected to the inner wall of the installation groove by a spring.
[0011] Specifically, the limiting arc-shaped rod corresponds to the connection point of the two fixed semi-ring plates, and the inner wall of the arc-shaped clamp plate is in contact with the outer wall of the fixed semi-ring plate and the upper sealing ring plate.

[0020] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Rather, the embodiments of this utility model include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.
[0021] The following description, in conjunction with the accompanying drawings, describes a rotatable, self-adjusting, pull-out friction-resistant pendulum support according to an embodiment of the present invention.
[0022] like Figures 1-4 As shown, a rotatable self-adjusting anti-pull-out friction pendulum support according to an embodiment of the present invention may include a lower seismic isolation support 1 and an upper seismic isolation support 11. A central rotating plate 12 is rotatably connected to both the lower seismic isolation support 1 and the upper seismic isolation support 11. A double spherical liner 13 is slidably connected between the two central rotating plates 12. Wear-resistant rotating plates 14 are installed at both ends of the double spherical liner 13.
[0023] Among them, two central rotating plates 12 are equipped with annular clamping plates 24 on their outer walls, and two fixed semi-annular plates 21 are provided between the two annular clamping plates 24. The two fixed semi-annular plates 21 are respectively connected to an upper sealing ring plate 22 and a lower sealing ring plate 23 at their ends. One end of the upper sealing ring plate 22 and the lower sealing ring plate 23 is in contact with the annular clamping plate 24. A limiting arc rod 3 is fixedly connected to the annular clamping plate 24. An arc clamping plate 31 is slidably connected to the inner wall of the limiting arc rod 3. The outer wall of the arc clamping plate 31 is in contact with the inner wall of the limiting arc rod 3.
[0024] It should be noted that the outer wall of the arc-shaped clamp 31 described in this embodiment is slidably connected to the inner wall of the limiting arc-shaped rod 3, and the limiting arc-shaped rod 3 has a certain length.
[0025] Specifically, the lower seismic isolation bearing 1 and the upper seismic isolation bearing 11 are used to connect with the upper and lower parts of the building's seismic isolation system during use. This allows the central rotating plate 12, installed on the connecting surfaces of the lower and upper seismic isolation bearings 1 and 11, to align vertically after the lower and upper seismic isolation bearings 1 and 11 are connected. The end face of the central rotating plate 12 is spherical, enabling it to connect and support the double spherical liner 13. A limiting element at the top of the central rotating plate 12 limits the position of the double spherical liner 13, ensuring that the lower seismic isolation bearing 1, the upper seismic isolation bearing 11, the central rotating plate 12, and the double spherical liner 13 have sufficient vertical support capacity to support the building structure. Simultaneously, the inner walls of the central rotating plate 12 and the double spherical liner 13 are tightly connected. The wear-resistant rotating plate 14, made of wear-resistant material, provides a tight support between the central rotating plate 12 and the double spherical liner 13. During an earthquake, the building experiences horizontal seismic forces, which are transmitted to the central rotating plate 12 via the connectors. This causes the double spherical liner 13 to slide on the sliding surface. During this sliding process, friction is generated between the central rotating plate 12 and the double spherical liner 13, converting the earthquake's energy into frictional heat. This energy conversion process reduces the impact of earthquakes on the building, achieving a damping effect. When using the device, because the isolation layer is in a humid environment for extended periods, the annular clamp 24, fixedly connected to the outer wall of the central rotating plate 12, corresponds vertically. The annular clamp 24 has a certain width, which... Synchronously sliding with the central rotating plate 12, the fixed semi-ring plate 21, which is clamped and slid between the annular clamping plates 24, can be tightly fitted against one end face of the annular clamping plate 24 by the connection and support of the upper sealing ring plate 22 and the lower sealing ring plate 23 installed at both ends. The fixed semi-ring plate 21 is fixed by the fixing frame 2, and the annular clamping plate 24 has sufficient width to allow it to move synchronously with the central rotating plate 12. With sufficient width of the annular clamping plate 24, the fixed semi-ring plate 21, the upper sealing ring plate 22, and the lower sealing ring plate 23 can maintain a tight fit with the end face of the annular clamping plate 24, while the upper sealing ring plate 22 and the lower sealing ring plate 23 are engaged with the upper and lower ends of the fixed semi-ring plate 21. The connection allows the upper sealing ring plate 22 and the lower sealing ring plate 23 to be separated from the fixed half-ring plate 21 for replacement. Simultaneously, the connection point of the fixed half-ring plate 21, the upper sealing ring plate 22, and the lower sealing ring plate 23 is fitted by the arc-shaped clamping plate 31. The outer wall of the arc-shaped clamping plate 31 is clamped and sealed by the limiting arc-shaped rod 3 fixedly connected to the top of the annular clamping plate 24. This ensures that the arc-shaped clamping plate 31 is stably supported between the fixed half-ring plates 21, and that the connection point of the fixed half-ring plate 21, the upper sealing ring plate 22, and the lower sealing ring plate 23 is tightly fitted and supported by the arc-shaped clamping plate 31, thus ensuring a seal. This ensures that the fixed half-ring plate 21, the upper sealing ring plate 22, the lower sealing ring plate 23, the annular clamping plate 24, and the limiting arc-shaped rod 3 form an assembly capable of sealing the gap between the central rotating plates 12.This reduces the ingress of impurities such as water into the central rotating plate 12, preventing damage to the connection between the double-spherical liner 13 and the wear-resistant rotating plate 14 and the central rotating plate 12, which could lead to rust and other adverse effects. Therefore, the device can ensure vibration isolation while extending its service life.
[0026] In one embodiment of this utility model, such as Figures 1-4 As shown, both the lower seismic isolation bearing 1 and the upper seismic isolation bearing 11 are provided with several connection holes 15, and one end of the central rotating plate 12 is fixedly connected to a support plate 111 that fits against one end of the lower seismic isolation bearing 1 and the upper seismic isolation bearing 11.
[0027] It should be noted that the connecting hole 15 described in this embodiment is used to connect with the upper and lower seismic isolation parts of the building. The support plate 111 is tightly attached to the upper and lower ends of the lower seismic isolation support 1 and the upper seismic isolation support 11. The support plate 111 and the central rotating plate 12 rotate on the lower seismic isolation support 1 and the upper seismic isolation support 11.
[0028] Specifically, the central rotating plate 12 is rotatably connected to the lower seismic isolation support 1 and the upper seismic isolation support 11, so that after the central rotating plate 12 is installed vertically, the lower seismic isolation support 1 and the upper seismic isolation support 11 can be rotated to easily adjust it to the position corresponding to the connecting bolts of the building structure, thereby facilitating the connection and use of the device. The support plate 111 is used to ensure that the central rotating plate 12 can be stably supported on the lower seismic isolation support 1 and the upper seismic isolation support 11, so that the support plate 111 can support the end face of the building structure.
[0029] In one embodiment of this utility model, such as Figures 1-4 As shown, four equally spaced fixing frames 2 are fixedly connected to the top of the lower seismic isolation bearing 1, and one end of the fixing frame 2 is connected to the outer wall of the fixed semi-ring plate 21.
[0030] It should be noted that the top of the fixing frame 2 described in this embodiment is at a height corresponding to the center position of the fixing semi-ring plate 21, and the top of the fixing frame 2 is offset from the annular clamp plate 24.
[0031] Specifically, the fixing frame 2, which is fixedly connected to the top of the lower seismic isolation bearing 1, can support and fix the outer wall of the fixed semi-ring plate 21. After the two fixed semi-ring plates 21 are connected and fixed on the lower seismic isolation bearing 1, the fixed semi-ring plates 21 are positioned by the height of the frame, so that the fixed semi-ring plates 21 can install the upper sealing ring plate 22 and the lower sealing ring plate 23, and the upper sealing ring plate 22 and the lower sealing ring plate 23 can fit against the end face of the annular clamp plate 24.
[0032] In one embodiment of this utility model, such as Figures 1-4As shown, a slot 25 is provided at the connection between the upper sealing ring plate 22 and the lower sealing ring plate 23 and the fixed half ring plate 21. A mounting groove 26 corresponding to the slot 25 is provided on the fixed half ring plate 21. A sliding column 27 is slidably connected to the inner wall of the mounting groove 26. The sliding column 27 is connected to the inner wall of the mounting groove 26 by a spring 28.
[0033] It should be noted that, in this embodiment, the sliding column 27 is in contact with the inner wall of the slot 25, and the upper sealing ring plate 22 and the fixed half-ring plate 21 are in contact with each other.
[0034] Specifically, the slots 25 opened on the upper sealing ring plate 22 and the lower sealing ring plate 23 allow the spring 28 to be compressed during installation, so that the spring 28 can be housed in the inner wall of the mounting groove 26. At this time, the sliding column 27 fixedly connected to the inner wall of the mounting groove 26 can provide elastic support for the spring 28. After the upper sealing ring plate 22 and the lower sealing ring plate 23 are aligned with the upper and lower ends of the fixed half-ring plate 21, the sliding column 27 is aligned with the slot 25 and supported by the spring 28, so that the sliding column 27 is engaged in the inner wall of the slot 25, thereby engaging and connecting the upper sealing ring plate 22, the fixed half-ring plate 21 and the lower sealing ring plate 23.
[0035] In one embodiment of this utility model, such as Figures 1-4 As shown, the limiting arc rod 3 corresponds to the connection between the two fixed semi-ring plates 21, and the inner wall of the arc clamp 31 is in contact with the outer wall of the fixed semi-ring plate 21, the upper sealing ring plate 22 and the lower sealing ring plate 23.
[0036] It should be noted that, in this embodiment, the limiting arc-shaped rod 3 is slidably connected to the arc-shaped clamping plate 31, and the fixed semi-ring plate 21, the upper sealing ring plate 22 and the lower sealing ring plate 23 are slidably connected to the arc-shaped clamping plate 31.
[0037] Specifically, by positioning the arc-shaped clamp 31 between the fixed semi-ring plate 21, the upper sealing ring plate 22, the lower sealing ring plate 23, and the limiting arc-shaped rod 3, the arc-shaped clamp 31 can slide and adjust its position, allowing the arc-shaped clamp 31 to be misaligned with the connection point of the fixed semi-ring plate 21. After the arc-shaped clamp 31 is misaligned with the connection point of the fixed semi-ring plate 21, the upper sealing ring plate 22 and the lower sealing ring plate 23 can be connected and engaged at the upper and lower ends of the fixed semi-ring plate 21. At the same time, after the upper sealing ring plate 22 and the lower sealing ring plate 23 are connected, the arc-shaped clamp 31 can be reset to seal its connection point.
[0038] In summary, the rotatable self-adjusting anti-pull-out friction pendulum support of this utility model embodiment provides sufficient vertical support capacity for the lower isolation support 1, upper isolation support 11, central rotating plate 12, and double spherical liner 13 during use. When an earthquake occurs, it converts horizontal forces into frictional heat, reducing the impact of earthquakes on buildings and achieving a damping effect. The annular clamping plate 24 has sufficient width to ensure that the fixed semi-annular plate 21, upper sealing ring plate 22, and lower sealing ring plate 23 remain tightly fitted to the end face of the annular clamping plate 24. Simultaneously, the connection between the fixed semi-annular plate 21, upper sealing ring plate 22, and lower sealing ring plate 23 is subjected to arc-shaped... The clamping of the clamping plate 31, with the outer wall of the arc-shaped clamping plate 31 being clamped and sealed by the limiting arc-shaped rod 3 fixedly connected to the top of the annular clamping plate 24, allows the arc-shaped clamping plate 31 to be stably supported between the fixed semi-annular plates 21. This ensures that the fixed semi-annular plates 21, the upper sealing ring plate 22, the lower sealing ring plate 23, the annular clamping plate 24, and the limiting arc-shaped rod 3 form a component that can seal the gap between the central rotating plates 12. This reduces the entry of impurities such as water into the central rotating plates 12, which could affect the connection between the double spherical liner plate 13 and the wear-resistant rotating plate 14 and the central rotating plate 12, causing rust and other adverse effects. As a result, the device can ensure vibration isolation while increasing its service life.
