[0026] 1. The adaptive modular plug-in steel-concrete seismic damping integrated device solves the problems of traditional viscous dampers such as single direction, difficult maintenance and lack of adaptability through the dynamic balance mechanism of the suspended sphere and the multi-stage sphere-spring buffer system.

[0027] 2. The adaptive modular plug-in steel-concrete seismic damping integrated device has a suspended sphere that moves freely on the arc-shaped bearing tray, adjusts its position through the first connecting rod (telescopic rod), balances the vibration energy in real time, and combines the telescopic characteristics of the first spring to achieve adaptive adjustment of the damping force and respond to external forces of different intensities and directions.

[0028] 3.

[0031] 6. The adaptive modular plug-in steel-concrete seismic damping integrated device uses the balance characteristics of the suspended sphere and the variable length design of the first connecting rod.

[0032] 7. The modular plug-in design of the adaptive modular plug-in steel-concrete seismic damping integrated device makes the installation, disassembly and maintenance of the device extremely convenient. During installation, each module can be quickly assembled; when maintaining or replacing parts, the operation is simple, saving time and labor costs.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Embodiment 1

[0042] See also Figure 1-Figure 4The adaptive modular plug-in steel-concrete seismic damping integrated device comprises a first bottom plate 10 and a second bottom plate 11. The second bottom plate 11 is arranged below the first bottom plate 10. A hanging sphere 21 is installed between the second bottom plate 11 and the first bottom plate 10 through a connecting mechanism. The hanging sphere 21 has a similar function to the hanging body, and is used for balance.

[0043] The first bottom plate 10 is provided with side fixing plates 13 on the front, back, left and right sides respectively, and the side fixing plates 13 are used to connect with the steel concrete;

[0044] A buffer mechanism 17 for shock absorption is installed in the middle of each side fixing plate 13;

[0045] A conduction rod 14 is installed on each buffer mechanism 17 . The conduction rod 14 is connected to the steel concrete. A first spring 20 is fixedly installed on the inner end of the conduction rod 14 . The four first springs 20 are all fixedly connected to the suspended sphere 21 .

[0046] By setting up the conduction rod 14 and connecting the conduction rod 14 to the steel concrete, modular connection is achieved, and the side fixing plate 13 can also be fixed on the steel concrete. During vibration, the steel concrete pushes the conduction rod 14 to conduct the vibration to the suspended sphere 21, and the elastic force of the first spring 20 achieves a shock-absorbing effect.

[0047] A connecting block 16 is fixedly and rotatably mounted on the outer end of the conducting rod 14 , and a fixing block 15 is mounted on the connecting block 16 , which is connected to the steel concrete through the fixing block 15 and bolts.

[0048] By the rotational connection between the connecting block 16 and the conducting rod 14, the direction of the fixing block 15 can be adjusted, so that it is more convenient to fix the connection with the steel concrete by bolts, and the effect of convenient installation is achieved in the process of modular connection.

[0049] Embodiment 2

[0050] Based on Example 1, please refer to Figure 1-Figure 5 The buffer mechanism 17 includes two circular blocks 25, each of which has a connecting groove 26 in the middle, and the conducting rod 14 is movably connected to the connecting groove 26. The two circular blocks 25 are respectively located on both sides of the two side fixing plates 13, and two limiting bars 36 are fixedly installed on 14, and the two limiting bars 36 are located on the outside of the two circular blocks 25;

[0051] A second slide groove 27 is formed on the side of each circular block 25 , and four second balls 30 are movably mounted in each second slide groove 27 .

[0052] A first slide groove 18 is opened in the middle position of the side fixing plate 13, and four assemblies 31 are installed in the first slide groove 18. Each assembly 31 is fixedly installed with two second connecting rods 29. The two second connecting rods 29 on each assembly 31 are fixedly connected to two adjacent second spheres 30 in the two connecting grooves 26.

[0053] When the conduction rod 14 conducts vibration, the two circular blocks 25 of the buffer mechanism 17 change position relative to the side fixing plate 13. Through the position limiting effect of the limit strip 36, the two circular blocks 25 are close to each other, and the elastic buffering effect of the assembly 31 is utilized to achieve a shock absorbing effect.

[0054] The four assemblies 31 are composed of two third spheres 32 as the main parts. A groove 33 is formed on the opposite side of the two third spheres 32. A third connecting rod 34 is movably installed in the groove 33.

[0055] A third spring 35 is fixedly mounted on the outer ring of the third connecting rod 34 , and the third spring 35 provides a rotational resilience force for the two third spheres 32 .

[0056] The second spheres 30 are spherical and can freely move and rotate in the second slide grooves 27. Second springs 28 are placed between the four second spheres 30 and are movably installed in the second slide grooves 27.

[0057] The assembly 31 is also formed by two spherical joints, and the assembly 31 can move and rotate freely in the first slide groove 18;

[0058] The first sphere 23 is also designed as a spherical structure, which is rotatably connected to the rotation groove 24 and can flexibly rotate in the rotation groove 24 .

[0059] The four assemblies 31 and the four groups of second spheres 30 are respectively arranged in the first slide groove 18 and the two second slide grooves 27, and the elastic force of the second spring 28 is used to make the four assemblies 31 and the four groups of second spheres 30 evenly arranged. When receiving vibration, the conduction rod 14 conducts the vibration. When the angle of the conduction rod 14 changes, the angle of the circular block 25 is driven to change. The elastic force of the second spring 28 is used to make the four assemblies 31 and the four groups of second spheres 30 change position in the first slide groove 18 and the second slide groove 27, thereby achieving the effect of shock absorption and the effect of adapting to changes.

[0060] Example 3, based on Example 2, please refer to Figure 1-Figure 6 A support column 19 is fixedly installed at the bottom of the second bottom plate 11, a support tray 12 is fixedly installed on the support column 19, and a suspended sphere 21 is placed on the support tray 12;

[0061] A rotation groove 24 is provided at the top of the hanging sphere 21 and the bottom of the first base plate 10. A first sphere 23 is rotatably installed in each rotation groove 24. A first connecting rod 22 is fixedly installed between the two first spheres 23. The first connecting rod 22 is designed as a telescopic rod connected by a spring.

[0062] The upper surface of the tray 12 is designed to be arc-shaped, and the suspended sphere 21 moves on the upper surface of the tray 12 . The movement of the suspended sphere 21 changes the length of the first connecting rod 22 .

[0063] By utilizing the bearing function of the support tray 12, when the suspended sphere 21 moves on the support tray 12, the movement of the suspended sphere 21 is restricted by utilizing the arc design of the upper surface of the support tray 12 and the gravity of the suspended sphere 21, thereby achieving a shock-absorbing effect. The restricting effect of the first connecting rod 22 also acts on the suspended sphere 21, so that the suspended sphere 21 returns to its original position, thereby achieving a shock-absorbing and buffering effect.

[0064] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
