Description

Technical Field

[0001] This invention relates to the field of building dampers, specifically to a magnetorheological damping tuned damper for super high-rise buildings. Background Technology

[0002] Earthquakes are a natural disaster that seriously threatens human life and property. In particular, in recent years, with the development of modern society, the number and size of cities have continued to expand, and cities have become areas with high population density and high concentration of wealth.

[0003] With economic development and social progress, people's material and cultural living standards have improved, leading to increasingly higher demands for living conditions. The rise of super high-rise buildings, in particular, has placed more stringent requirements on the safety and applicability of seismic design. Traditional seismic design methods sometimes fail to meet the actual needs of engineering projects. Therefore, researching safer, more economical, and reliable new methods for structural seismic resistance is a major issue currently facing the field of structural seismic resistance. Structural vibration control theory, developed over the past thirty years, offers a valuable new method for addressing this problem and has significant practical implications for effectively mitigating earthquake disasters.

[0004] Currently, existing high-rise building dampers typically use a combination of multiple small dampers for support and buffering. The support and buffering effect of small dampers is limited, and they cannot efficiently buffer and reduce vibrations in the counterweight system. Furthermore, the sway amplitude of the magnetohydrodynamic tuned mass is large, resulting in low safety.

[0005] Therefore, it is necessary to invent a magnetorheological damping tuned damper for super high-rise buildings to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a magnetorheological damping tuned damper for super high-rise buildings, in order to solve the problems mentioned in the background art, such as the limited support and buffering effect of small dampers, the inability to efficiently buffer and reduce vibration of the counterweight system, and the large sway amplitude and low safety of the magnetorheological tuned mass block.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a magnetorheological damping tuned damper for ultra-high-rise buildings, comprising a magnetorheological tuning body and a top fixing frame, wherein the top fixing frame is located above the magnetorheological tuning body, and a mounting frame assembly is sleeved on the outer side of the magnetorheological tuning body; steel cables are connected at equal intervals along the top edge of the mounting frame assembly, and the upper ends of the steel cables are connected to the top fixing frame. A bottom support frame assembly is provided below the magnetofluidic tuning body. The bottom support frame assembly includes a bottom ring. Large hydraulic cylinder viscous dampers are movably connected at equal intervals to the upper edge of the bottom ring. The end of the large hydraulic cylinder viscous damper away from the bottom ring is connected to a mounting frame assembly. A base plate is fixed at equal intervals to the side wall of the bottom ring. A buffer limiting assembly is fixed to the upper end of the side of the base plate away from the bottom ring. The buffer limiting assembly includes a limiting seat. Supports are fixed to the upper and lower ends of the limiting seat near the magnetofluidic tuning body. A fixed seat is provided between the upper and lower supports. A support slide rod is connected between the fixed seat and the support. A movable ring seat is slidably sleeved on the support slide rod. An anti-collision buffer damper is movably connected to the movable ring seat. The end of the anti-collision buffer damper away from the movable ring seat is movably connected to the mounting frame assembly. A first buffer spring is provided between the movable ring seat and the support. A second buffer spring is provided between the movable ring seat and the fixed seat.

[0008] Preferably, the first and second buffer springs are both sleeved on the support slide rod, and the fixed seat is fixedly installed on the limiting seat. The support slide rod provides limiting support for the first and second buffer springs, preventing them from bending when compressed.

[0009] Preferably, the movable ring seat has a channel, and the movable ring seat is sleeved on the support slide rod through the channel. The upper, lower and middle inner walls of the channel are movably embedded with balls at equal intervals. The balls abut against the surface of the support slide rod, thereby reducing the friction between the movable ring seat and the support slide rod and reducing frictional loss between the movable ring seat and the support slide rod.

[0010] Preferably, the magnetohydrodynamic tuning body is spherical, and the mounting frame assembly includes an upper fixing ring and a lower fixing ring. The upper fixing ring is fixedly sleeved on the upper part of the magnetohydrodynamic tuning body, and the lower fixing ring is fixedly sleeved on the lower part of the magnetohydrodynamic tuning body. A connecting block is fixed between the upper fixing ring and the lower fixing ring. The number of connecting blocks is set to multiple, and the multiple connecting blocks are distributed in a ring array around the magnetohydrodynamic tuning body. An arc-shaped mesh frame is fixed to the bottom of the lower fixing ring. The arc-shaped mesh frame is sleeved on the outer bottom of the magnetohydrodynamic tuning body. The mounting frame assembly can effectively fix the magnetohydrodynamic tuning body, so that the magnetohydrodynamic tuning body is placed stably and securely in the mounting frame assembly.

[0011] Preferably, the lower end of the steel rope is connected to the upper fixed ring, the end of the anti-collision buffer damper away from the moving ring seat is movably connected to the connecting block, and the end of the large hydraulic cylinder viscous damper away from the bottom ring is connected to the bottom of the lower fixed ring. The large hydraulic cylinder viscous damper supports the mounting frame assembly, thereby supporting the magnetohydrodynamic tuning body and effectively reducing the tension received by the steel rope.

[0012] Preferably, the upper and lower anti-collision buffer dampers are arranged in a figure-eight structure, which can effectively buffer the movement of the magnetohydrodynamic tuning body and prevent the magnetohydrodynamic tuning body from shaking too much.

[0013] Preferably, the top fixing frame includes a fixed top ring, and top plates are fixed at equal intervals on the side wall of the fixed top ring. The upper end of the steel rope is connected to the fixed top ring. By connecting the fixed top ring and the top plates to the top wall of the high-rise building, the stability of the installation of this magnetorheological damping tuned damper can be improved.

[0014] Preferably, a support plate is fixed to the top of the limiting seat, and the upper end of the support plate is fixedly connected to the bottom of the top plate. The support plate supports the top plate, thereby improving the stability of the top plate installation.

[0015] Preferably, the bottom of the limiting seat is fixedly connected to the upper side of the base plate, the bottom of the support located below is fixedly connected to the upper side of the base plate, and a first reinforcing plate is fixed between the support located above and the support plate. The support plate is supported by the first reinforcing plate, so that the connection between the support plate and the support is stable and reliable.

[0016] Preferably, a second reinforcing plate is fixed between the support plate and the bottom edge of the top ring. The second reinforcing plate improves the support effect on the top ring, making the top ring installation stable.

[0017] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0018] 1. By incorporating a large hydraulic cylinder viscous damper, an anti-collision buffer damper, a first buffer spring, and a second buffer spring, when the magnetohydrodynamic tuning body sways, the large hydraulic cylinder viscous damper can effectively support and buffer the magnetohydrodynamic tuning body. At the same time, the anti-collision buffer damper, the first buffer spring, and the second buffer spring can further buffer the magnetohydrodynamic tuning body, reducing the amplitude of the swaying of the magnetohydrodynamic tuning body. This effectively reduces the vibration and swaying of the building, providing excellent protection for high-rise buildings.

[0019] 2. By using a large hydraulic cylinder viscous damper and steel rope in combination, the magnetohydrodynamic tuning body can be effectively supported when it is stationary, so that the magnetohydrodynamic tuning body is stable when it is stationary.

[0020] 3. This device has a simple structure. By setting a support plate, a first reinforcing plate and a second reinforcing plate, the limiting seat can effectively support the top fixed frame, making the top fixed frame stable during installation. Attached Figure Description

Detailed Implementation

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] This invention provides, for example Figure 1-9 The diagram illustrates a magnetorheological damping tuned damper for a super high-rise building, comprising a magnetorheological tuning body 1 and a top fixing frame 2. The top fixing frame 2 is located above the magnetorheological tuning body 1. A mounting frame assembly 3 is sleeved on the outer side of the magnetorheological tuning body 1. Steel cables 4 are connected at equal intervals along the top edge of the mounting frame assembly 3, with the upper ends of the steel cables 4 connected to the top fixing frame 2. A bottom support frame assembly 5 is disposed below the magnetorheological tuning body 1. The bottom support frame assembly 5 includes a bottom ring 6. Large hydraulic cylinder viscous dampers 7 are movably connected at equal intervals along the upper edge of the bottom ring 6. The end of the large hydraulic cylinder viscous damper 7 away from the bottom ring 6 is connected to the mounting frame assembly 3. A base plate 8 is fixed at equal intervals along the side wall of the bottom ring 6. A buffer limiting assembly is fixed at the upper end of the side of the base plate 8 away from the bottom ring 6. The buffer limiting assembly includes a limiting seat 9, with supports 10 fixed at both the upper and lower ends of the limiting seat 9 near the magnetorheological tuning body 1. A fixed seat 11 is provided between the upper and lower supports 10. A support slide rod 12 is connected between the fixed seat 11 and the support 10. A movable ring seat 13 is slidably sleeved on the support slide rod 12. An anti-collision buffer damper 14 is movably connected to the movable ring seat 13. The end of the anti-collision buffer damper 14 away from the movable ring seat 13 is movably connected to the mounting frame assembly 3. A first buffer spring 15 is provided between the movable ring seat 13 and the support 10. A second buffer spring 16 is provided between the movable ring seat 13 and the fixed seat 11.

[0035] The first buffer spring 15 and the second buffer spring 16 are both sleeved on the support slide rod 12. The fixed seat 11 is fixedly installed on the limiting seat 9. The support slide rod 12 provides limiting support for the first buffer spring 15 and the second buffer spring 16, preventing the first buffer spring 15 and the second buffer spring 16 from bending when compressed.

[0036] The movable ring seat 13 has a channel 17, and the movable ring seat 13 is sleeved on the support slide rod 12 through the channel 17. The upper and lower ends and the middle inner wall of the channel 17 are movably embedded with balls 18 at equal intervals. The balls 18 abut against the surface of the support slide rod 12, thereby reducing the friction between the movable ring seat 13 and the support slide rod 12 and reducing the frictional loss between the movable ring seat 13 and the support slide rod 12.

[0037] The magnetohydrodynamic tuning body 1 is spherical. The mounting frame assembly 3 includes an upper fixing ring 19 and a lower fixing ring 20. The upper fixing ring 19 is fixedly sleeved on the upper part of the magnetohydrodynamic tuning body 1, and the lower fixing ring 20 is fixedly sleeved on the lower part of the magnetohydrodynamic tuning body 1. A connecting block 21 is fixed between the upper fixing ring 19 and the lower fixing ring 20. Multiple connecting blocks 21 are arranged in a ring array around the magnetohydrodynamic tuning body 1. An arc-shaped mesh frame 22 is fixed to the bottom of the lower fixing ring 20. The arc-shaped mesh frame 22 is sleeved on the outer bottom of the magnetohydrodynamic tuning body 1. The mounting frame assembly 3 can effectively fix the magnetohydrodynamic tuning body 1, making the magnetohydrodynamic tuning body 1 stable and securely placed inside the mounting frame assembly 3.

[0038] The lower end of the steel rope 4 is connected to the upper fixed ring 19. The end of the anti-collision buffer damper 14 away from the moving ring seat 13 is movably connected to the connecting block 21. The end of the large hydraulic cylinder viscous damper 7 away from the bottom ring 6 is connected to the bottom of the lower fixed ring 20. The large hydraulic cylinder viscous damper 7 supports the mounting frame assembly 3, thereby supporting the magnetohydrodynamic tuning body 1 and effectively reducing the tension received by the steel rope 4.

[0039] The two anti-collision buffer dampers 14 are arranged in a figure-eight structure, which can effectively buffer the movement of the magnetohydrodynamic tuning body 1 and prevent the magnetohydrodynamic tuning body 1 from shaking too much.

[0040] The top fixing frame 2 includes a fixed top ring 23, and top plates 24 are fixed at equal intervals on the side wall of the fixed top ring 23. The upper end of the steel rope 4 is connected to the fixed top ring 23. The fixed top ring 23 and the top plate 24 are connected to the top wall of the high-rise building, which can improve the stability of the installation of this magnetorheological damping tuned damper.

[0041] The specific implementation method is as follows: the top fixing frame 2 is connected to the top wall of the super high-rise building, and the bottom support frame assembly 5 is connected to the bottom wall of the super high-rise building. When an earthquake or strong wind causes the super high-rise building to vibrate or sway, the magnetohydrodynamic tuning body 1 sways, squeezing the large hydraulic cylinder viscous damper 7 and the anti-collision buffer damper 14 in the corresponding direction. The large hydraulic cylinder viscous damper 7 and the anti-collision buffer damper 14 exert forces in opposite directions on the magnetohydrodynamic tuning body 1, thereby buffering the magnetohydrodynamic tuning body 1. Simultaneously, the anti-collision buffer damper 14 is compressed by the first buffer spring 15 and the second buffer spring 16. The first buffer spring 15 and the second buffer spring 16 can buffer and decompose the force on the anti-collision buffer damper 14, further improving the buffering effect, reducing the swaying amplitude of the magnetohydrodynamic tuning body 1, improving safety performance, and simultaneously reducing vibration, thus reducing the vibration or swaying of high-rise buildings. This embodiment specifically solves the problems in the prior art where the support and buffering effect of small dampers is limited, they cannot efficiently buffer and reduce vibration of the counterweight system, and the magnetohydrodynamic tuning mass block has a large swaying amplitude and low safety.

[0042] like Figure 1 and Figure 7 As shown, a support plate 25 is fixed to the top of the limiting seat 9. The upper end of the support plate 25 is fixedly connected to the bottom of the top plate 24. The support plate 25 supports the top plate 24, thereby improving the stability of the installation of the top plate 24.

[0043] The bottom of the limiting seat 9 is fixedly connected to the upper side of the base plate 8, the bottom of the support 10 located below is fixedly connected to the upper side of the base plate 8, and a first reinforcing plate 26 is fixed between the support 10 located above and the support plate 25. The support plate 25 is supported by the first reinforcing plate 26, so that the connection between the support plate 25 and the support 10 is stable and reliable.

[0044] A second reinforcing plate 27 is fixed between the support plate 25 and the bottom edge of the top ring 23. The second reinforcing plate 27 improves the support effect on the top ring 23, making the top ring 23 more stable.

[0045] The specific implementation method is as follows: the limiting seat 9 and the support plate 25 can effectively support the top fixing frame 2, improving the installation stability of the top fixing frame 2. At the same time, the first reinforcing plate 26 supports the support plate 25, making the connection between the support plate 25 and the support 10 stable and reliable. The second reinforcing plate 27 improves the support effect on the top ring 23, making the installation of the top ring 23 stable, further improving the installation stability of the top fixing frame 2. Thus, the top fixing frame 2 can effectively suspend the magnetohydrodynamic tuning body. This implementation method specifically solves the problem of poor installation stability and easy fall of the top fixing frame in the prior art.

[0046] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
