Description
Technical Field
[0001] The present application relates to the technical field of assembled earthquake-resistant buildings, and in particular to an assembled self-resetting shock-absorbing frame structure. Background Art
[0002] Earthquakes are sudden, highly destructive natural disasters. In the field of civil engineering, various technologies have emerged to address earthquake disasters, such as energy-absorbing shock absorption technology using dampers, seismic isolation technology using isolation bearings, and tuned shock absorption using vibration absorbers. Traditional structural seismic design dissipates input seismic energy through elastic-plastic deformation of structural components to prevent the structure from collapsing during a major earthquake. Although buildings do not collapse after a major earthquake, structural and non-structural components suffer significant damage and excessive residual deformation. Reinforcement and straightening of permanent deformations are economically costly and technically difficult, leading to demolition and reconstruction.
[0003] The Chinese invention patent with publication number CN102912878A discloses a modular building seismic isolation system, including modular units, unit connectors and seismic isolation layers, wherein the modular units are box-type load-bearing bodies composed of square steel pipe columns, steel beams, walls, floor slabs and rigid tie rods; the modular units are assembled through the unit connectors in the following manner: the rigid tie rods pass through the protrusions of the unit connectors and the small holes on the end plates, and are fixed on the unit connectors, so that the square steel pipe columns on the upper layer and the square steel pipe columns on the lower layer are connected through the unit connectors and the rigid tie rods; the seismic isolation layer includes seismic isolation supports, upper concrete slabs, lower concrete slabs, steel supports, and square steel pipe columns. The bottom modular units are fixedly connected to the upper concrete handles of the seismic isolation layer through the unit connectors.
[0004] Regarding the above-mentioned related technologies, the related technologies lack a solution for the self-reset of the structure after an earthquake, and the connection method between the unit connectors and the isolation layer will lead to poor shock absorption effect, and there is still room for improvement in the shock absorption effect. Summary of the Invention
[0005] In order to improve the problem of low shock absorption effect in the prior art, the present application provides an assembled self-resetting shock absorption frame structure.
[0006] The following technical solutions are adopted:
[0007] A prefabricated self-resetting shock-absorbing frame structure comprises a frame body, a plurality of movable seats and a plurality of bases, wherein the plurality of movable seats are connected in an array to one side of the frame body, and the plurality of movable seats are respectively slidably connected to the corresponding bases, and a reset mechanism is provided between the base and the movable seat to make the movable seat have a tendency to slide toward an initial position, and a plurality of buffer disks are rotatably connected in an array around the base, and the buffer disks are provided with a driven shaft along the rotation center, and a plurality of driving shafts are provided circumferentially of the movable seat at positions corresponding to the buffer disks, and a transmission mechanism is provided between the movable seat and the driving shaft to convert the linear motion of the movable seat into the rotational motion of the driving shaft, the buffer disk includes a driven shaft, and a torque converter mechanism is provided at one end of the driving shaft to transmit the torque of the driving shaft to the driven shaft through hydraulic force.
[0008] By adopting the above technical solution, the frame body is connected to the moving seat, and the moving seat and the base slide relative to each other. When the seismic shear wave is transmitted to the frame body, the frame body is pushed to reciprocate in the horizontal direction, that is, the moving seat slides back and forth relative to the base. The horizontal movement of the moving seat is converted into the rotational movement of the active shaft through the transmission mechanism, thereby driving the active shaft to rotate, so that the active shaft transmits torque to the torque converter mechanism to drive the driven shaft to rotate, and the horizontal displacement trend of the frame body is alleviated by the buffer disk to alleviate the vibration of the frame body; at the same time, the reset mechanism makes the frame body have a tendency to slide to the initial position after the vibration is alleviated.
[0009] Optionally, the torque converter mechanism includes a housing, an impeller and a turbine, the housing is connected to the base, the impeller and the turbine are arranged opposite to each other and are respectively rotatably connected in the housing, the driving shaft is connected to the side of the impeller away from the turbine, the driven shaft is connected to the side of the turbine away from the impeller, and the housing is filled with liquid transmission medium.
[0010] By adopting the above technical solution, the driving shaft is driven to rotate by the transmission mechanism. After the driving shaft rotates, it drives the pump wheel to rotate to stir the transmission medium to burst toward the turbine. The transmission medium impacts the turbine in a turbulent manner to drive the turbine to rotate, so that the driving shaft rotates, thereby rotating the buffer disk, and finally alleviating the vibration of the frame body.
[0011] Optionally, the turbine and the impeller both include a bowl-shaped wheel shell, the openings of the wheel shells of the turbine and the impeller are arranged facing each other, and the wheel shells are both provided with a plurality of blades in a circumferential array.
[0012] By adopting the above technical solution, when the driving shaft is running, it drives the impeller to rotate together with it. Under the action of centrifugal force, the liquid transmission medium at the impeller rushes from the outer edge of the impeller blades to the turbine, and flows from the outside to the inside along the turbine blades. The liquid transmission medium flows back to the inner edge of the impeller blades through the inside of the turbine, forming a circulating liquid flow. Through the bowl-shaped structure, the vortex formed during the transmission between the impeller and the turbine is made more stable.
[0013] Optionally, the transmission mechanism includes a connecting rod, a gear rod and a gear, one end of the connecting rod is rotatably connected to the movable seat, and the other end is rotatably connected to the gear rod, and a guide sleeve is provided on the base to limit the movement of the gear rod along the length direction of the gear rod, the gear rotates coaxially with the driving shaft, and the gear rod is engaged with the gear.
[0014] By adopting the above technical solution, through the hinge between the moving seat and the connecting rod, the connecting rod pushes the gear rod to move, the gear rod drives the gear meshing with it to rotate, the gear rotates with the driving shaft, thereby driving the pump wheel to rotate, so as to transfer the momentum brought by the moving seat to the buffer disk.
[0015] Optionally, the gear rod is a rectangular rod, and a through slot is provided on one side of the gear rod along its length direction. The gear is rotatably connected in the through slot, and the gear rod is provided with teeth along the length on the inner wall of one side where the through slot is located, and the gear is engaged with the teeth.
[0016] By adopting the above technical solution, the gear is rotatably connected in the through slot, providing support for the gear in two directions to increase the structural stability of the gear. A tooth pattern that meshes with the gear is provided on one side of the through slot, so that the gear rod can drive the gear to rotate when it moves.
[0017] Optionally, the reset mechanism includes a plurality of buffer balls, and a plurality of limit grooves are arrayed on the movable seat, the limit grooves are arc-shaped, and the radius of the limit grooves is larger than the radius of the buffer balls, and a plurality of the buffer balls are respectively arranged in the plurality of limit grooves, and a plurality of abutment grooves are opened on the base, whose positions correspond to the limit grooves, and the radius of the abutment grooves is equal to that of the buffer balls.
[0018] By adopting the above technical solution, the movable seat is pressed onto the buffer ball through the limiting groove. Since the limiting groove is an arc-shaped groove with a radius larger than the radius of the buffer ball, even if the movable seat is offset due to vibration, the movable seat will always be at a position where the highest point of the limiting groove is tangent to the buffer ball under the action of gravity.
[0019] Optionally, a combination groove is provided in the base, and a connecting groove connected to the combination groove is provided on one side of the base. The movable seat includes an end block, a combination disk and a connecting column. The end block is connected to the combination disk through the connecting column. The combination disk is arranged in the combination groove, and the connecting column can be slid through the connecting groove.
[0020] By adopting the above technical solution, the sliding range of the combined disk is limited by the combined groove, and the connecting column and the connecting groove cooperate to provide a more stable restriction for the movable seat and the base to prevent the movable seat from detaching from the base.
[0021] Optionally, a first buffer layer is provided on the outer wall of the connecting column along its circumference, and a second buffer layer is provided on the inner wall of the base where the connecting groove is located.
[0022] By adopting the above technical solution, the impact force when the connecting column collides with the base after moving is reduced, so as to protect the connecting column from being broken by the pile foundation.
[0023] In summary, this application has at least one of the following beneficial effects:
[0024] 1. The cooperation between the movable seat and the buffer ball enables the frame body to have the ability to self-reset after being impacted by an earthquake;
[0025] 2. After the frame body is impacted, the movement of the moving seat is converted into the rotational movement of the driving shaft through the transmission mechanism, driving the driving shaft to rotate, thereby eliminating the horizontal displacement of the frame body through the buffer disk to alleviate the vibration of the frame body.

[0031] The following is combined with Figure 1 To the attached Figure 4 This application is described in further detail.
[0032] Reference Figure 1 and Figure 2 The embodiment of the present application discloses an assembled self-resetting shock-absorbing frame structure, comprising a frame body 1, a plurality of movable seats 2 and a plurality of bases 3. A movable seat 2 is connected to the support column 11 of each frame body 1. A rectangular connecting sleeve 24 is provided on one side of the movable seat 2. The support column 11 is passed through the connecting sleeve 24 and connected by a steel bar 12. The movable seat 2 is slidably connected to the base 3. A reset mechanism is provided between the base 3 and the movable seat 2 to make the movable seat 2 have a tendency to slide toward the initial position. A plurality of buffer disks 5 are rotatably connected to the circumference of the base 3. The buffer disk 5 is provided with a driven shaft 51 along the rotation center. The movable seat 2 is provided with a plurality of driving shafts 631 at positions corresponding to the buffer disks 5 respectively. A transmission mechanism 6 is provided between the movable seat 2 and the driving shaft 631 to convert the linear motion of the movable seat 2 into the rotational motion of the driving shaft 631. A torque converter 7 is provided at one end of the driving shaft 631 to transmit the torque of the driving shaft 631 to the driven shaft 51 through hydraulic transmission.
[0033] Reference Figure 3 and Figure 4Specifically, the torque converter mechanism 7 includes a housing 71, an impeller 72, and a turbine 73. A first support plate 35 is provided on the base 3. The housing 71 is connected to the base 3 via the first support plate 35. The impeller 72 and turbine 73 are disposed opposite each other and are rotatably connected within the housing 71. The driving shaft 631 is connected to the side of the impeller 72 away from the turbine 73, and the driven shaft 51 is connected to the side of the turbine 73 away from the impeller 72. The housing 71 is filled with a liquid transmission medium, which is hydraulic oil. The turbine 73 and the impeller 72 both include a bowl-shaped wheel shell 721. The openings of the wheel shells 721 of the turbine 73 and the impeller 72 face each other. Each wheel shell 721 is provided with a plurality of blades 722 arranged in a circumferential array, and the blades 722 are inclined from the side wall toward the center of rotation. The driving shaft 631 is driven to rotate by the transmission mechanism 6. When the driving shaft 631 is running, it drives the pump impeller 72 to rotate together with it to stir the transmission medium. Under the action of centrifugal force, the liquid transmission medium at the pump impeller 72 is rushed to the turbine 73 from the outer edge of the pump impeller 72 blade 722. The transmission medium impacts the turbine 73 in a turbulent manner to drive the turbine 73 to rotate, so that the driven shaft 51 rotates. Since the blades 722 are inclined, the transmission medium flows from the outside to the inside along the blades 722 of the turbine 73. The liquid transmission medium flows back to the inner edge of the blades 722 of the pump impeller 72 through the inside of the turbine 73, forming a circulating liquid flow, thereby causing the buffer disk 5 to rotate, and finally alleviating the vibration of the frame body 1.
[0034] Reference Figure 2 and Figure 3 The transmission mechanism 6 includes a connecting rod 61, a gear rod 62, and a gear 63. One end of the connecting rod 61 is rotatably connected to the movable base 2, and the other end is rotatably connected to the gear rod 62. A guide sleeve 34 is provided on the base 3 to limit the movement of the gear rod 62 along the length of the gear rod 62. The guide sleeve 34 is arranged in an array corresponding to the gear rod 62. The guide sleeve 34 is a hollow rectangular sleeve. One side of the guide sleeve 34 is connected to the base 3. The gear rod 62 passes through the guide sleeve 34 and meshes with the gear 63. The gear 63 rotates coaxially with the driving shaft 631, and the gear rod 62 meshes with the gear 63. A second support plate 36 is provided on the base 3 for supporting the driving shaft 631 and the driven shaft 51. The driving shaft 631 and the driven shaft 51 are both rotatably connected to the second support plate 36. Through the hinge between the moving seat 2 and the connecting rod 61, the connecting rod 61 pushes the gear rod 62 to move, and the gear rod 62 drives the gear 63 engaged with it to rotate. The gear 63 rotates together with the driving shaft 631, thereby driving the pump wheel 72 to rotate to transfer the momentum brought by the moving seat 2 to the buffer disk 5.
[0035] Reference Figure 2 and Figure 3The gear rod 62 is a rectangular rod with a through slot 621 extending along its length. The gear 63 is rotatably connected to the through slot 621. The gear rod 62 has teeth 622 along its length along the inner wall of the side where the through slot 621 is located. The gear 63 meshes with the teeth 622. The gear 63 is rotatably connected to the through slot 621, providing support in two directions for the gear 63 and increasing its structural stability. The through slot 621 has teeth on one side that mesh with the gear 63, enabling the gear 63 to rotate as the gear rod 62 moves.
[0036] Reference Figure 3 The reset mechanism includes a number of buffer balls 41. A number of limiting grooves 231 are arranged in an array on the movable seat 2. The limiting grooves 231 are arc-shaped grooves. The radius of the limiting grooves 231 is larger than the radius of the buffer balls 41, and the buffer balls 41 are respectively arranged in the limiting grooves 231. The base 3 is provided with a number of abutting grooves 33 corresponding to the limiting grooves 231. The abutting grooves 33 are semicircular arc structures. The radius of the abutting grooves 33 is equal to that of the buffer balls 41. The movable seat 2 is pressed onto the buffer balls 41 through the limiting grooves 231. Since the radius of the limiting grooves 231 is larger than the radius of the buffer balls 41, even if the movable seat 2 is offset due to vibration, the movable seat 2 will always be at a position where the highest point of the limiting grooves 231 is tangent to the buffer balls 41 under the action of gravity. The limiting grooves 231 and the abutting grooves 33 are both paved with reinforcing plates 232 that fit the inner walls.
[0037] Reference Figure 3 The base 3 is a truncated cone-shaped structure. A cylindrical combination groove 31 is provided at the center of the base 3. A connecting groove 32 connected to the combination groove 31 is provided on one side of the base 3. The movable base 2 includes an end block 21, a combination disk 23, and a connecting column 22. The connecting column 22 is fixed to one side of the end block 21. The side of the connecting column 22 away from the end block 21 is connected to the combination disk 23. The combination disk 23 can slide in the combination groove 31. The diameter of the combination groove 31 is larger than the diameter of the combination disk 23. The connecting column 22 passes through the connecting groove 32. The diameter of the connecting groove 32 is larger than the outer diameter of the connecting groove 32. The sliding range of the combination disk 23 is limited by the combination groove 31. The connecting column 22 and the connecting groove 32 cooperate to provide a more stable restriction for the movable base 2 and the base 3 to prevent the movable base 2 from separating from the base 3.
[0038] Reference Figure 3 A first buffer layer 221 is provided on the outer wall of the connecting column 22 along its circumference, and a second buffer layer 321 is provided on the inner wall of the base 3 where the connecting groove 32 is located. It is used to reduce the impact force when the connecting column 22 collides with the base 3 after moving, so as to protect the connecting column 22 from breaking.
[0039] The implementation principle of the assembled self-resetting shock-absorbing frame structure in the embodiment of the present application is as follows:
[0040] The frame body 1 is connected to the moving seat 2, and the moving seat 2 slides relative to the base 3. When the seismic shear wave is transmitted to the frame body 1, the frame body 1 is pushed to reciprocate in the horizontal direction, that is, the moving seat 2 slides back and forth relative to the base 3. The horizontal movement of the moving seat 2 is converted into the rotational movement of the active shaft 631 through the transmission mechanism 6, thereby driving the active shaft 631 to rotate, so that the active shaft 631 transmits torque to the torque converter 7 to drive the driven shaft 51 to rotate, and the horizontal displacement trend of the frame body 1 is alleviated by the buffer disk 5, thereby alleviating the vibration of the frame body 1; at the same time, the reset mechanism makes the frame body 1 have a tendency to slide to the initial position after the vibration is alleviated.
[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
