Description

Technical Field

[0001] This utility model relates to the field of seismic isolation bearing technology, specifically a friction pendulum vibration dual-control device. Background Technology

[0002] Seismic isolation bearings are support devices installed on structures to meet seismic isolation requirements. They involve adding a seismic isolation layer between the superstructure and the foundation and installing rubber seismic isolation bearings to provide a flexible connection with the ground. This technology can offset about 80% of the energy from an earthquake.

[0003] The published patent document CN215055879U discloses a friction pendulum vibration dual-control device. When the device is subjected to a lateral force, the upper and lower supports undergo relative lateral displacement under the action of the rolling element. The friction pendulum assembly provides lateral damping, preventing the elastic telescopic component from being subjected to lateral forces. When the device is subjected to a vertical force, the friction pendulum assembly transmits vertical vibration, while the elastic telescopic component provides vertical vibration isolation, achieving decoupling of vertical and lateral forces. The bidirectional movements do not interfere with each other, solving the problem of inconsistent horizontal and vertical vibration scales, thus enhancing controllability and applicability. However, the aforementioned patent requires friction between the supports during the damping process, which may damage the supports. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] Please see Figure 1-4 This utility model provides a technical solution: it includes a lower support 1, a middle support 2, and an upper support 3. Four sets of vertical vibration damping components 8 and several vertical springs 17 are arranged between the lower support 1 and the middle support 2. Four sets of horizontal vibration damping components 9 are arranged between the middle support 2 and the upper support 3. Each set of vertical vibration damping components 8 includes a base plate 801 and a vertical rod 802. The base plate 801 is fixedly installed on the top of the lower support 1, and four uprights 803 are fixedly connected to the top of the base plate 801. The uprights 803 are fitted with... A matching damping sleeve 804 is provided. A vertical rod 802 is fixedly installed at the bottom of the middle support 2, and a connecting plate 805 is fixedly connected to the lower end of the vertical rod 802. A matching damping sleeve 806 is fixedly connected to each of the four corners of the connecting plate 805. The damping sleeve 806 is fitted onto the damping sleeve 804. Each set of horizontal vibration damping components 9 includes a rectangular frame 901, a rectangular frame 902, a slider 903, and a slider 904. The rectangular frame 901 is fixedly installed... The bottom of rectangular frame 902 is fixedly installed on the top of the middle support 2, and the top of slider 903 is fixedly installed on the bottom of the upper support 3. Static damping plates 905 are fixedly connected to the inner walls of the front and rear sides of rectangular frame 901, and a limiting shaft 909 is fixedly installed inside rectangular frame 901. Slider 903 is located inside rectangular frame 901, and dynamic damping plates 907 are fixedly connected to the front and rear sides of slider 903. The limiting shaft 909 passes through... Slider 903, and springs 911 are sleeved on both sides of limiting shaft 909. Static damping plates 906 are fixedly connected to the inner walls of both sides of rectangular frame 902. Limiting shaft 910 is fixedly installed inside rectangular frame 902. Slider 904 is located inside rectangular frame 902. Dynamic damping plates 908 are fixedly connected to both sides of slider 904. Limiting shaft 910 passes through slider 904. Springs 912 are sleeved on both sides of limiting shaft 910.

[0024] In this technical solution, when the device is subjected to vertical vibration, the vertical spring 17 is compressed and reset, and the damping sleeve 806 slides and rubs along the damping sleeve 804 to dissipate vertical kinetic energy. When the device is subjected to horizontal vibration, the slider 903 compresses one spring 911 and stretches the other spring 911 and resets. At this time, the dynamic damping plate 907 and the static damping plate 905 dissipate horizontal kinetic energy. When the device is subjected to horizontal longitudinal vibration, the slider 904 compresses one spring 912 and stretches the other spring 912 and resets. At this time, the dynamic damping plate 908 and the static damping plate 906 dissipate horizontal longitudinal kinetic energy, realizing dual-control vibration reduction function and good vibration reduction effect.

[0025] In some technical solutions, such as Figure 1 and Figure 5 As shown, a rubber sleeve 4 is provided between the lower support 1 and the middle support 2. All four sets of vertical vibration damping components 8 are located inside the rubber sleeve 4, and the outer wall of the rubber sleeve 4 is provided with a wavy edge 13. A rubber sleeve 5 is provided between the middle support 2 and the upper support 3. All four sets of horizontal vibration damping components 9 are located inside the rubber sleeve 5, and the outer wall of the rubber sleeve 5 is provided with a wavy edge 14.

[0026] In use, the sound generated by the vertical vibration damping component 8 is weakened by the rubber sleeve 4 and the wavy edge 13 on its outer wall, and the sound generated by the horizontal vibration damping component 9 is weakened by the rubber sleeve 5 and the wavy edge 14 on its outer wall, so that the device has good noise reduction performance.

[0027] In some technical solutions, such as Figure 1 and Figure 5 As shown, sealing ring 15 is symmetrically fixedly connected to the top and bottom of rubber sleeve 4, and sealing ring 16 is symmetrically fixedly connected to the top and bottom of rubber sleeve 5.

[0028] During use, sealing ring 15 ensures the sealing between rubber sleeve 4 and lower support 1 and middle support 2, and sealing ring 16 ensures the sealing between rubber sleeve 5 and middle support 2 and upper support 3.

[0029] In some technical solutions, such as Figure 4 As shown, U-shaped parts 10 are provided on the lower front and rear sides of the rectangular frame 2 902. The U-shaped parts 10 are fixedly installed on the top of the middle support 2, and a sliding shaft 11 is fixedly installed inside the U-shaped parts 10. A sliding rod 12 is sleeved on the sliding shaft 11 and slidably connected to it. The top of the sliding rod 12 is fixedly installed to the bottom of the rectangular frame 2 902.

[0030] In use, the sliding shaft 11 limits the sliding rod 12, ensuring the stability of the movement of the rectangular frame 902.

[0031] In some technical solutions, such as Figure 1-2 As shown, mounting holes 6 are provided at the four corners of the lower support 1.

[0032] In use, the lower support 1 can be easily connected to the ground through the mounting hole 6.

[0033] In some technical solutions, such as Figure 1-2 As shown, the upper support 3 has several fixing holes 7.

[0034] In use, the upper support 3 can be easily connected to the building structure through the fixing hole 7.

[0035] Working principle: When the device is subjected to vertical vibration, the vertical spring 17 is compressed and reset, and the damping sleeve 806 slides and rubs along the damping sleeve 804 to dissipate vertical kinetic energy. When the device is subjected to horizontal vibration, the slider 903 compresses one spring 911 and stretches the other spring 911 and resets. At this time, the dynamic damping plate 907 and the static damping plate 905 dissipate horizontal kinetic energy. When the device is subjected to horizontal longitudinal vibration, the slider 904 compresses one spring 912 and stretches the other spring 912 and resets. At this time, the dynamic damping plate 908 and the static damping plate 906 dissipate horizontal longitudinal kinetic energy. The sound caused by the vertical vibration damping component 8 is weakened by the rubber sleeve 4 and the wavy edge 13 on its outer wall. The sound caused by the horizontal vibration damping component 9 is weakened by the rubber sleeve 5 and the wavy edge 14 on its outer wall.
