[0039] The main fixed steel plate 3 is further provided with a third gear 81 connected to the second gear 8 by teeth. A fourth gear 82 is coaxially provided on the side of the third gear 81 away from the main fixed steel plate 3. A gear one-way adjustment device is provided on the main fixed steel plate 3. The fourth gear 82 is connected to the fifth gear 83 by teeth. The tail end of the fifth gear 83 is slidably engaged in the gear one-way adjustment device. The fifth gear 83 is used to adjust the contact relationship between the fifth gear 83 and the sixth gear 88 and the eighth gear 89 when the direction of the fourth gear 82 changes, so as to ensure that the rotation direction of the sixth gear 88 and the eighth gear 89 remains unchanged.
[0040] The main fixed steel plate 3 is also provided with a sixth gear 88 and an eighth gear 89 that mesh horizontally. The sixth gear 88 and the eighth gear 89 are of the same size and their centroids are located on the same horizontal line. The sixth gear 88 or the eighth gear 89 is provided with a seventh gear 881 on the side wall away from the main fixed steel plate 3.

[0041] Furthermore, the gear one-way adjustment device includes a curved slide 85 and a fixed connecting plate 86 fixed on both sides of the curved slide 85, the fixed connecting plate 86 is connected to the fourth pad 87 through a cantilever connecting rod 861, and is fixed on the main fixed steel plate 3; a slider 84 is provided at the tail of the fifth gear 83, and the slider 84 is slidably set in the curved slide 85; the cross-section of the slider 84 is trapezoidal as a whole, and the slider 84 is embedded in the curved slide 85. The function of the curved slide 85 is to limit the position of the slider 84 and the fifth gear 83, ensuring that the fifth gear 83 is always located between the fourth gear 82 and the sixth gear 88 and the eighth gear 89.
[0042] Preferably, Figure 3 As shown, this embodiment provides two groups of second transmission structures, and the two groups of second transmission structures correspond to one group of energy dissipation devices respectively. The second transmission structure includes a first fixed plate 41 and a second fixed plate 42 vertically arranged on the lower beam 1, one side of the second fixed plate 42 is the energy dissipation device, and two parallel and spaced vertical support rods 43 are arranged on the lower beam 1 on the other side; the two vertical support rods 43 are horizontally spaced and provided with the same lower end limit piece 44 and upper end limit piece 46, and a linkage piece 45 is slidably provided on the two vertical support rods 43 between the lower end limit piece 44 and the upper end limit piece 46; it also includes a gear reciprocating rotation mechanism, the input end of the gear reciprocating rotation mechanism is fixed to the first fixed plate 41, and the teeth are connected to the linkage chain 7, and the output end of the gear reciprocating rotation mechanism is rotatably arranged on the second fixed plate 42, and is transmission-connected to the energy dissipation device;
[0043] Further, such as Figure 7As shown, the gear reciprocating rotation mechanism includes a slave gear 74 connected to the teeth of the linkage chain 7, and a first turntable 48 rotatably set on the second fixed plate 42, and a universal rotation connecting rod 75 is provided between the slave gear 74 and the first turntable 48; the rotating shaft of the slave gear 74 is fixedly set on the first fixed plate 41, and the first gear 47 is fixedly set on the end of the universal rotation connecting rod 75 away from the slave gear 74. When the slave gear 74 rotates, the first gear 47 can rotate synchronously. The end face of the first turntable 48 close to the first gear 47 is provided with an arc-shaped convex structure 481, and the curved surfaces of the arc-shaped convex structure 481 are all designed A tooth-like structure is provided, which meshes with the first gear 47, and an upper end limit member 46 and a lower end limit member 44 are respectively provided above and below the linkage member 45. The function of the upper end limit member 46 and the lower end limit member 44 is to limit the position of the linkage member 45, that is, to limit the position of the first gear 47, to ensure that the first gear 47 is always engaged with the tooth-like structure on the arc-shaped convex structure 481; a turntable rotating shaft 49 is provided on the side of the first turntable 48 close to the second fixed plate 42, and the turntable rotating shaft 49 can be rotatably passed through the second fixed plate 42; when the slave gear 74 maintains unidirectional rotation, the first turntable 48 periodically changes its rotation direction.
[0044] When the energy consumption capacity requirement is not high or the centroid of the seventh gear 881 is located relatively to one side between the lower beam 1 and the upper beam 2, that is, the rotating steel belt 71 cannot be longer, all the slave gears 74 can be connected to the seventh gear 881 through a linkage chain 7 to ensure common rotation.
[0045] When the energy dissipation capacity is required to be high or the centroid of the seventh gear 881 is located in a relatively central position between the lower beam 1 and the upper beam 2, that is, the rotating steel belt 71 can be longer, the slave gear 74 on one side of the main fixed steel plate 3 can be connected to the seventh gear 881 through a linkage chain 7, and the slave gear 74 on the other side can be connected to the seventh gear 881 through another linkage chain 7;
[0046] When the swing amplitude of the rotating steel belt 71 is large, structural interference may occur, so its length is greatly limited by the swing amplitude.
[0047] Further, such as Figure 8 As shown, the energy dissipation device includes a rotating steel belt 71 and multiple friction energy dissipation steel belts 72 arranged perpendicular to the rotating steel belt 71. The adjacent friction energy dissipation steel belts 72 are respectively arranged on both sides of the rotating steel belt 71, and the two ends of the friction energy dissipation steel belt 72 are respectively detachably fixed in the clamping groove chain 73; it should be noted that the rotating steel belt 71 is provided with multiple friction energy dissipation steel belts 72 on the vertical line of the extension direction, and the rotating steel belt 71 and the friction energy dissipation steel belt 72 form a woven structure.
[0048] The rotating steel belt 71 is made of a relatively rigid steel or alloy coated with a high-friction rubber material. During production, attention should be paid to chamfering to minimize stress concentration. The friction energy dissipation steel belt 72 is made of a relatively elastic alloy material coated with a high-friction rubber material. During production, attention should be paid to chamfering to minimize stress concentration. In addition, the alloy material and the high-friction rubber material should be connected by dense ribs or rivets on the outside of the alloy material to minimize slippage between the alloy material and the high-friction rubber material. The high-friction rubber material coated with the alloy material has the characteristics of high elasticity, high strength and easy processing, which is beneficial to the energy dissipation and production of the braided structure. In addition, although both the rotating steel belt 71 and the friction energy dissipation steel belt 72 have great friction, those skilled in the art should combine the physical and mechanical properties of the high-friction rubber material and the structural characteristics of the braided structure to ensure that the rotating steel belt 71 can swing smoothly within the braided structure. As long as the rotating steel belt 71 can rotate repeatedly, combined with the high friction characteristics of the rotating steel belt 71 and the friction energy dissipation steel belt 72, it can be ensured that the braided structure as a whole provides extremely high energy dissipation capacity for the mechanical damping device of this application.
[0049] Preferably, Figure 6 As shown, the clamping groove chain 73 includes a plurality of fixed blocks connected in sequence, and the fixed blocks are U-shaped structures. Specifically, the U-shaped structure is two spaced-apart clamping plates 731 and a bottom plate 732 fixedly arranged at the bottom of the same side of the two clamping plates 731. The U-shaped groove is detachably fixedly connected to the friction energy dissipation steel belt 72 by a pin, and two first connecting plates 733 are alternately arranged in parallel on one side of the adjacent U-shaped grooves, and a second connecting plate 734 adapted to the structure of the two first connecting plates 733 is arranged on the other side. The two first connecting plates 733 and the second connecting plates 734 of the adjacent U-shaped grooves are detachably connected; further, the top of the clamping groove chain 73 is detachably connected to the embedded part of the upper beam 2, and the bottom of the clamping groove chain 73 is connected to the lower beam 1 through an elastic component; further, as Figure 9 As shown, the elastic component includes a fifth pad 735 arranged on the lower beam 1, and a hole connecting plate 736 arranged on the fifth pad 735, and the bottom of the groove chain 73 is connected to the hole connecting plate 736 through a spring damping member 737.
[0050] Preferably, a third pad 61 is provided at the bottom of the upper beam 2 , and a plurality of diagonal bracing rods 6 are provided between the third pad 61 and the linkage crossbar 5 , wherein the diagonal bracing rods 6 are micro-deformable flexible rods.
[0051] When the present application is in use, when the lower beam 1 and the upper beam 2 produce horizontal relative displacement, the linkage cross bar 5 drives the second gear 8 connected to its teeth to rotate, the second gear 8 drives the third gear 81 to rotate, the third gear 81 drives the fourth gear 82 to rotate, and the fourth gear 82 drives the fifth gear 83 to rotate. While the fifth gear 83 is rotating, its tail end slider 84 will slide in the curved slide groove 85 and approach the sixth gear 88 or the eighth gear 89. When the fifth gear 83 contacts the sixth gear 88 or the eighth gear 89, a tooth connection is generated, and the sixth gear 88 or the eighth gear 89 is driven to rotate, and the seventh gear 881 set on the sixth gear 88 or the eighth gear 89 rotates at the same time, driving the linkage chain 7 to transmit; the transmission chain 7 drives the slave gear 74 to rotate, and the slave gear 74 drives the universal rotating link 75 to rotate, and the first gear 47 rotates with the universal rotating link 75 and moves along the tooth-shaped structure outside the arc-shaped convex structure 481. The first gear 47 rotates along the inner and outer sides of the arc-shaped convex structure 481, and the first turntable 48 rotates in the opposite direction. When the first gear 47 has completed running on the inner and outer sides of the arc-shaped convex structure 481, it is a movement cycle. The first turntable 48 drives the rotating steel belt 71 to rotate during the rotation. It should be noted that in order to ensure that the swinging angle of the rotating steel belt 71 is consistent during the two-way swinging process, the number of tooth-shaped structures on the inner and outer sides of the arc-shaped convex structure 481 is consistent, so that the offset of the rotating steel belt 71 to both sides in one cycle is consistent. During the rotation of the rotating steel belt 71, it is necessary to overcome the friction between the rotating steel belt 71 and the friction energy dissipation steel belt 72, as well as the force generated by the deformation of the friction energy dissipation steel belt 72, to realize the energy dissipation process.
[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
