Description

Technical Field

[0001] This utility model relates to the field of vibration damping technology, specifically to a wind-resistant vibration damping tuned mass damping device. Background Technology

[0002] A tuned mass damper, also known as a tuned mass shock absorber or tuned mass damper, is a vibration control device commonly used in high-rise buildings, bridges, and other large structures. A tuned mass damper is a passive structural control measure that uses specific tuning parameters and the interaction between the tuned mass block and the main structure to reduce the vibration amplitude of high-rise buildings under strong winds or earthquakes.

[0003] Utility model CN215253619U discloses a bidirectional tuned mass damping vibration reduction device, including a mounting frame, a vibration reduction system, and a guiding device. The mounting frame includes an upper connecting plate and a lower connecting plate. The vibration reduction system includes several suspension elements, several helical compression springs, several vertical dampers, a mass block, and several horizontal damping devices. The suspension elements, horizontal damping devices, and mass block constitute a horizontal vibration reduction system, and the helical compression springs, vertical dampers, and mass block constitute a vertical vibration reduction system. The guiding device includes several linear bearings, several linear bearing guide rods, and a pair of horizontal sliding bearings.

[0004] The above-mentioned technical solution, by sharing a tuned mass block, can achieve coordinated control of horizontal and vertical structural vibrations, and uses spring elements and suspension elements to achieve dynamic vibration absorption. It has the characteristics of simple construction and convenient processing. However, the application of ultra-thin canopies, eaves and other building components is gradually increasing. Ultra-thin components cause obvious vibrations under wind loads, which is visually uncomfortable. Ordinary vibration reduction devices are large and bulky, and their use affects the aesthetic requirements of the building. They do not have the thinness and increased vibration reduction effect of damping devices. Utility Model Content

[0005] The purpose of this invention is to provide a wind-resistant, vibration-damping, tuned mass damping device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wind-resistant, vibration-damping, tuned mass damping device includes a top cover connected to a base box. A cross-shaped support plate is located in the center of the base box. Damping blocks are located on both sides of the support plate at its center position. A sealing gasket is located on the lower surface of the top cover corresponding to the inner wall of the base box. A damping seat is located below the base box. A collar is located at the center of the upper surface of the damping seat, and a sliding groove is formed in the middle of the collar. A sliding column is located on the lower surface of the base box corresponding to the sliding groove. An installation groove is located on the upper surface of the damping seat near a corner, and a damping spring is installed in each installation groove. A circular groove is located on the lower surface of the base box corresponding to the damping spring.

[0008] Furthermore, a limiting plate is provided on the upper surface of the damping seat near the corner. The limiting plate is L-shaped, and a limiting groove is provided on the lower surface of the base box corresponding to the limiting plate.

[0009] In this invention, the four limiting plates cooperate with each other and are inserted into the corresponding limiting slots to achieve a stable combination and installation of the damping seat and the base box, which helps to stabilize the up and down movement.

[0010] Specifically, the collar and the damping seat are integrally formed, the inner diameter of the slide groove is adapted to the outer diameter of the slide column, the top of the slide column is welded and fixed to the bottom of the base box, and the length of the slide column is less than the depth of the slide groove.

[0011] In this invention, the collar with a groove helps the sliding column move up and down in the groove, and the damping seat works together with the base box to increase the base box's wind resistance and vibration reduction performance.

[0012] It should be noted that one end of the damping spring is bonded and fixed to the bottom of the mounting groove, and the other end of the damping spring extends into the circular groove and is bonded and fixed to its top.

[0013] In this invention, the damping spring has elasticity and, in conjunction with the damping seat, further enhances vibration reduction performance. The fit between the circular groove and the mounting groove facilitates the installation of the damping spring.

[0014] Furthermore, the top of the sealing gasket is bonded and fixed to the bottom of the top cover, the width of the outer wall of the sealing gasket is adapted to the width of the inner wall of the bottom box, and countersunk holes are provided on the upper surface of the top cover near the corners, and fastening bolts are provided in the countersunk holes. Screw holes are provided on the top of the bottom box at the corresponding positions of the fastening bolts.

[0015] In this invention, the sealing gasket enhances the sealing performance between the top cover and the bottom box, and the fastening bolts, through the countersunk hole and the screw hole, achieve stability in the combined installation of the top cover and the bottom box.

[0016] Secondly, the four end posts of the support plate are tightly fitted to the corners of the inner wall of the bottom box and welded and fixed. The vibration damping block is in the shape of a disc, and each vibration damping block has a screw groove. The upper vibration damping block has a positioning bolt in the screw groove. The positioning bolt passes through the upper vibration damping block and the middle position of the support plate in sequence, and is threadedly connected to the screw groove on the lower vibration damping block.

[0017] In this invention, two damping blocks are assembled with a support plate, and with the help of positioning bolts, the damping blocks and the support plate are fixed together.

[0018] It is worth noting that the inner wall of the bottom box is also filled with damping fluid, and the level of the damping fluid is in contact with the bottom of the sealing gasket.

[0019] In this invention, the damping fluid is an oily liquid. It relies on the viscous resistance of the liquid medium to reduce the kinetic energy of the moving machinery, shorten the mechanical swing or movement time, and the damping fluid is used to reduce vibration and impact, making the mechanical movement more stable.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model uses a top cover with a sealing gasket and a bottom box for fixed assembly. The bottom box is filled with damping fluid. The damping fluid works together with the support plate and the damping block. The viscous resistance causes the kinetic energy of the moving machine to decrease, shortening the mechanical swing or movement time. A damping seat is installed under the base, and with the cooperation of four damping springs, they work together to further reduce the impact of vibration on the whole.

[0022] 2. This utility model increases the stability of the installation of the top cover and the bottom box by setting the fastening bolts to pass through the countersunk hole and the screw hole for threaded connection. The sliding column and the collar are connected by a sliding groove, and the limiting plate and the limiting groove are connected by a sliding groove, which increases the stability of the vertical displacement between the bottom box and the damping seat.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Please see Figures 1-6 This embodiment provides a technical solution:

[0036] A wind-resistant vibration-damping tuned mass damping device includes a bottom box 1 and a top cover 2 connected to the bottom box 1. The bottom box 1 has a cross-shaped support plate 14 in the middle. The support plate 14 has damping blocks 15 on both sides at the middle position.

The positioning bolt 151 passes through the upper damping block 15 and the middle position of the support plate 14 in sequence and is threadedly connected to the screw groove 150 on the lower damping block 15.

[0037] In this utility model, two damping blocks 15 are assembled with a support plate 14, and with the cooperation of the positioning bolt 151, the damping blocks 15 and the support plate 14 are fixed together.

[0038] Furthermore, a sealing gasket 20 is provided on the lower surface of the top cover 2 corresponding to the inner wall of the bottom box 1. The top of the sealing gasket 20 is bonded and fixed to the bottom of the top cover 2. The width of the outer wall of the sealing gasket 20 is adapted to the width of the inner wall of the bottom box 1. Countersunk holes 21 are provided on the upper surface of the top cover 2 near the corners. Fastening bolts 210 are provided in the countersunk holes 21. Screw holes 10 are provided on the top of the bottom box 1 corresponding to the fastening bolts 210.

[0039] In this invention, the sealing gasket 20 enhances the sealing performance between the top cover 2 and the bottom box 1, and the fastening bolt 210 passes through the countersunk hole 21 and is threadedly connected to the screw hole 10, thereby achieving stability in the combined installation of the top cover 2 and the bottom box 1.

[0040] It should be noted that a damping seat 3 is provided below the bottom box 1, and a limiting plate 31 is provided on the upper surface of the damping seat 3 near the corner. The limiting plate 31 is L-shaped, and a limiting groove 12 is provided on the lower surface of the bottom box 1 corresponding to the limiting plate 31.

[0041] In this utility model, the four limiting plates 31 cooperate with each other and are inserted into the corresponding limiting grooves 12 to achieve a stable combination and installation of the damping seat 3 and the base box 1, which helps to move up and down stably.

[0042] Specifically, a collar 30 is provided at the center of the upper surface of the damping seat 3, and a groove 300 is provided in the middle of the collar 30. A sliding post 13 is provided on the lower surface of the bottom box 1 at the position corresponding to the groove 300. The collar 30 and the damping seat 3 are integrally formed. The inner diameter of the groove 300 is adapted to the outer diameter of the sliding post 13. The top of the sliding post 13 is welded and fixed to the bottom of the bottom box 1. The length of the sliding post 13 is less than the depth of the groove 300.

[0043] In this utility model, the collar 30 with the groove 300 helps the sliding column 13 to move up and down in the groove 300. The damping seat 3 and the base box 1 work together to increase the wind resistance and vibration reduction performance of the base box 1.

[0044] Furthermore, a mounting groove 32 is provided on the upper surface of the damping seat 3 near the corner, and a damping spring 320 is provided in each mounting groove 32. A circular groove 11 is provided on the lower surface of the bottom box 1 at the position corresponding to the damping spring 320.

[0045] Secondly, the collar 30 and the damping seat 3 are integrally formed structures, the inner diameter of the slide groove 300 is adapted to the outer diameter of the slide column 13, the top of the slide column 13 is welded and fixed to the bottom of the base box 1, and the length of the slide column 13 is less than the depth of the slide groove 300.

[0046] In this utility model, the collar 30 with the groove 300 helps the sliding column 13 to move up and down in the groove 300. The damping seat 3 and the base box 1 work together to increase the wind resistance and vibration reduction performance of the base box 1.

[0047] It is worth adding that the inner wall of the bottom box 1 is also filled with damping fluid 4, and the level of damping fluid 4 is in contact with the bottom of the sealing gasket 20.

[0048] In this invention, the damping fluid 4 is an oily liquid. It relies on the viscous resistance of the liquid medium to reduce the kinetic energy of the moving machinery, shorten the mechanical swing or movement time, and the damping fluid 4 is used to reduce vibration and impact, making the mechanical movement more stable.

[0049] In this embodiment, the wind-resistant vibration reduction tuned mass damping device is first used by combining the damping block 15 with the support plate 14 and fixing its position with the positioning bolt 151. The four ends of the support plate 14 are then combined and fixed with the bottom box 1. The bottom box 1 is then filled with damping liquid 4, which submerges the damping block 15. The top cover 2 with the sealing gasket 20 is combined and fixed with the bottom box 1 and threadedly connected by fastening bolts 210 through the countersunk hole 21 and the screw hole 10 to increase the stability of the installation. Then, the damping seat 3 is inserted into the limiting groove 12 through the limiting plate 31, and the damping spring 320 connects the circular groove 11 and the mounting groove 32. The sliding column 13 is inserted into the sliding groove 300 in the collar 30 to increase the stability of the combination.

[0050] When high-rise buildings interact with each other, the damping spring 320 and the damping seat 3 work together, and the damping fluid 4 and the vibration damping block 15 on the support plate 14 work together to reduce and absorb the amplitude. At the same time, the overall combined structure is thin and does not affect the aesthetics of the overall building, thus increasing the vibration reduction performance.
