[0002] In the field of building engineering, in order to reduce the need for shock absorption, a shock absorption device is often arranged between the vertical walls of a building, and the main part of the shock absorption device that plays a role in shock absorption is a viscous damper. The viscous damper converts the energy input into the building wall structure by the interaction of the piston and the viscous fluid into heat energy dissipation hysteresis deformation to dissipate, so as to reduce the seismic response of the building structure, thereby avoiding the destruction or collapse of the structure, and achieving the purpose of shock absorption control.

[0042] The assembly converts the high-speed low-torque output of the driving member 71 into low-speed high-torque power through the worm 72 and the worm wheel 73 transmission pair, and through power transmission, the large torque demand required for the lifting of the lead screw 76 can be adapted, and the self-locking property of the worm wheel 73 and the worm 72 can prevent the bearing plate 8 from accidentally sliding down due to gravity or external force, thereby providing safety guarantee for the maintenance process.

[0043] Specifically, the second bevel gear 75 can receive the rotating power transmitted by the first bevel gear 74 and drive the lead screw 76 to rotate synchronously, the lead screw 76 is connected with the center shaft of the second bevel gear 75 through threads, when the second bevel gear 75 rotates, the lead screw 76 moves linearly along the axial direction, driving the bearing plate 8 and the lifting plate 9 to lift synchronously, that is, the lifting of the bearing plate 8 is realized through the cooperation of the thread pair, and then the lifting of the shock absorber 5 during maintenance is realized. The gear ratio of the second bevel gear 75 and the first bevel gear 74 can further adjust the rotating speed of the lead screw 76. In the application, the bearing plate 8 is synchronously driven by a plurality of lifting assemblies 7, the weight of the shock absorber 5 can be balanced, the gear number of the worm wheel 73, the worm 72, the first bevel gear 74 and the second bevel gear 75 can be set according to the transmission ratio requirement, and the lifting speed requirement can be met.

At the same time, the support plate 6 and the lifting assembly 7 are both installed inside the second wall body 2, without occupying external space, and the lifting assembly 7 is withdrawn into the second wall body 2 when the shock damper 5 does not need to be lifted, and the lead screw 76 of the lifting assembly 7 drives the bearing plate 8 to extend out of the second wall body 2 and rise below the shock damper 5 when the shock damper 5 needs to be lifted, and the lifting plate 9 is used to lift the shock damper 5.

[0046] In order to stably lift the shock damper 5 during maintenance, the lifting plate 9 is provided with a storage groove 91 matched with the shock damper 5, and the lifting plate 9 is used to directly bear the shock damper 5, and the storage groove 91 is matched with the bottom of the shock damper 5 to stably support the shock damper 5.

A buffer can be provided on the storage groove 91, which can reduce damage to the shock damper 5 when the shock damper 5 is placed in the storage groove 91 after disassembly.

[0048] The first mounting plate 61, the second mounting plate 62 and the third mounting plate 63 are arranged on the bearing plate 8, one end of the worm 72 is rotatably mounted on the first mounting plate 61, the other end is rotatably mounted on the second mounting plate 62, the first rotating shaft 64 is arranged in the center axis extension direction of the worm wheel 73, the first rotating shaft 64 is mounted on the third mounting plate 63, the transmission module 77 includes a third bevel gear 771 and a fourth bevel gear 772, the third bevel gear 771 is meshingly connected with the fourth bevel gear 772, the third bevel gear 771 is sleeved on the first rotating shaft 64, the second rotating shaft 65 is arranged on the center axis extension line of the fourth bevel gear 772, the first bevel gear 74 is sleeved on the second rotating shaft 65, the bearing plate 8 is provided with a support 66, the fourth bevel gear 772 is rotatably mounted on the support 66, and the screw rod 76 is mounted on the extension line of the center axis of the second bevel gear 75 through threaded connection.

[0049] The first mounting plate 61 provides a rotating support point for one end of the worm 72, and the second mounting plate 62 provides a rotating support for the other end of the worm 72. The common arrangement of the first mounting plate 61 and the second mounting plate 62 can ensure that the worm 72 can stably rotate, reducing the shaking and deviation during the rotation of the worm 72, so that the power can be stably transmitted from the driving member 71 to the worm 72, and then to the worm wheel 73, thereby improving the transmission reliability. The third mounting plate 63 is used for mounting the first rotating shaft 64, providing support and positioning for the rotation of the worm wheel 73, so that the power can be smoothly transmitted from the worm 72 to the worm wheel 73.

[0050] The third bevel gear 771 is sleeved on the first rotating shaft 64 and can synchronously rotate with the worm wheel 73. The third bevel gear 771 is meshingly connected with the fourth bevel gear 772, transmits the power of the worm wheel 73 to the fourth bevel gear 772, changes the direction of power transmission and adjusts the speed, so as to meet the requirements of the lifting of the screw rod 76.

[0051] The second rotating shaft 65 provides a support basis for the fourth bevel gear 772, and the first bevel gear 74 is sleeved on the second rotating shaft 65 and synchronously rotates with the fourth bevel gear 772. The first bevel gear 74 is meshingly connected with the second bevel gear 75, the second bevel gear 75 receives the power transmitted by the first bevel gear 74, transmits the power to the second bevel gear 75, and provides power for the rotational rotation of the screw rod 76.

[0052] The support 66 provides rotating support for the fourth bevel gear 772 and is fixed on the bearing plate 8, so as to ensure that the fourth bevel gear 772 can stably rotate and ensure the normal work of the transmission module 77.

[0053] The power transmission direction is changed and the speed is adjusted through the cooperation of multi-stage transmission and bevel gears, so that the power of the driving member 71 can be efficiently transmitted to the lead screw 76, realizing the rapid lifting of the bearing plate 8 and improving the maintenance efficiency. Through the design of the transmission module 77 and the bevel gear, the transmission direction of the power is changed, so that the transmission system can adapt to the space layout on the bearing plate 8, fully utilize the limited space, and improve the compactness and practicability of the device.

[0054] Specifically, a threaded hole for cooperating with the lead screw 76 is arranged in the center axis extension direction of the second bevel gear 75 and in the support 66. The threaded hole in the center axis of the second bevel gear 75 cooperates with the external threads of the lead screw 76, so that the rotational motion of the second bevel gear 75 is converted into the linear motion of the lead screw 76 through the threaded pair. When the second bevel gear 75 is driven to rotate by the first bevel gear 74, the lead screw 76 moves up and down along the axial direction, driving the bearing plate 8 to move synchronously; the threaded hole in the support 66 is connected to the other end of the lead screw 76, providing a support point for the lead screw 76, and the axial movement and radial swing of the lead screw 76 are constrained through the threaded hole, ensuring that the lead screw 76 maintains linear motion and bearing capacity when lifting.

[0055] The two ends of the bearing plate 8 away from the lifting assembly 7 are hingedly connected with baffle plates 81, and the bearing plate 8 is connected with hard springs 82 on both sides. The other end of the hard spring 82 is connected with the baffle plate 81, and the baffle plate 81 is hingedly connected to the two ends of the bearing plate 8 and can rotate around the hinge point. The baffle plate 81 is deflected inward by the tension of the hard spring 82, forming a lateral limiting structure for the shock absorber 5 to reduce the risk of falling of the shock absorber 5.

[0056] The baffle plate 81 and the bearing plate 8 are connected by the hard spring 82 and are hingedly arranged. They are not rigidly fixed and can rotate slightly with the shape of the shock absorber 5 or the installation error, reducing the risk of damaging the shock absorber 5 shell due to hard impact.

[0057] During the lifting of the bearing plate 8, the baffle plate 81 limits the lateral movement of the shock absorber 5 by contacting the side surface of the shock absorber 5, ensuring that the shock absorber is always located on the lifting plate 9 and avoiding the risk of uneven stress or falling due to deviation.

[0058] A buffer is installed on one side of the baffle plate 81 close to the shock absorber 5. The buffer can be made of elastic materials such as rubber, silicone, sponge or polyurethane, etc. The buffer absorbs impact energy through elastic deformation of the material, reducing the rigid contact between the baffle plate 81 and the shock absorber 5. When the baffle plate 81 contacts the shock absorber due to the tension of the hard spring 82, the buffer reduces the contact stress by compressive deformation, avoiding direct extrusion of the baffle plate 81 structure on the shock absorber 5 shell, effectively protecting the structural integrity of the shock absorber 5.

[0059] Reference Figures 1-4The second wall body 2 is provided with a mounting groove 21, the mounting groove 21 is provided with a base plate 3, the base plate 3 is provided with a bearing plate 8, a plurality of buffer assemblies 4 are arranged between the base plate 3 and the bearing plate 8, the mounting groove 21 provides mounting space for the base plate 3, and the mounting groove 21 can be formed by pre-buried or later excavation; the upper surface of the base plate 3 is provided with the bearing plate 8 and a lifting assembly 7, and the lower surface is fixed with the mounting groove 21 through bolts or welding, and the load of the bearing plate 8 is transmitted to the wall structure.

[0060] The buffer assembly 4 can absorb vibration energy and reduce the influence of the lifting assembly 7 on the whole device in the lifting impact. When the shock absorber 5 is maintained, the buffer assembly 4 can assist the bearing plate 8 to stably lift, so as to avoid impact damage to the shock absorber 5 or the transmission component.

[0061] Specifically, referring to Figure 4 The buffer assembly 4 includes a sleeve 41 and a support rod 42, one end of the support rod 42 is sleeved in the sleeve 41, the other end is connected with the bearing plate 8, the sleeve 41 is connected with the base plate 3, one end of the support rod 42 is connected with a limiting plate 43, the limiting plate 43 is located in the sleeve 41, and the limiting plate 43 is connected with the bottom of the sleeve 41. A spring 44 is arranged between the limiting plate 43 and the bottom of the sleeve 41. A relatively smooth cylindrical cavity is formed in the sleeve 41, which provides vertical sliding guide for the support rod 42, limits the transverse displacement of the support rod 42, and ensures the stable linear motion of the bearing plate 8 during lifting. The sleeve 41 also serves as a containing space for the spring 44 and the limiting plate 43, and the bottom of the sleeve 41 is connected with the base plate 3, bears the compression reaction force of the spring 44, and transmits the impact force to the base plate 3 and the wall structure.

[0062] With the lifting of the bearing plate 8, the limiting plate 43 and the spring 44 move, and the support rod 42 transmits the impact load of the bearing plate 8 to the spring 44.

[0063] The limiting plate 43 is fixed to one end of the support rod 42 extending into the sleeve 41, and the size of the limiting plate 43 is smaller than the inner diameter of the sleeve 41, so as to prevent the support rod 42 from being completely taken out of the sleeve 41. When the bearing plate 8 is impacted, kinetic energy is absorbed through compression or stretching deformation and converted into elastic potential energy for storage; after the impact disappears, the elastic potential energy is released to push the bearing plate 8 back to the original position.

[0064] The buffer assembly 4 works cooperatively through the sleeve 41 guide, the support rod 42 force transmission, the limiting plate 43 stroke limiting and the spring 44 buffering, forms dynamic vibration, absorbs energy through the elastic deformation of the spring 44 during the lifting process of the bearing plate 8 or building vibration, the limiting plate 43 limits the stroke, the sleeve 41 and the support rod 42 ensure the movement precision, realize the buffering, vibration reduction and guiding of the bearing plate 8, and improve the stability and safety of the device.

[0065] The protective cover is arranged on the driving member 71, the worm gear 73, the worm 72, the transmission assembly, the first bevel gear 74 and the second bevel gear 75 and the like, so that foreign matters are prevented from entering the inside of the gear and affecting the operation. The cover plate is arranged on the installation groove 21. When the shock damper 5 does not need to be overhauled, the bearing plate 8 and the lifting plate 9 are lowered into the installation groove 21 through the lifting assembly 7, and the internal structure is protected through the cover plate, so that the service life of the device is prolonged.

[0068] The shock damper 5 is fixedly connected with the first wall body 1 and the second wall body 2 at both ends, normally bears the displacement and load generated by the building vibration, consumes energy through the damping characteristic, and reduces the relative movement between the walls.

[0069] The bearing plate 8 is in the installation groove 21 under the driving of the lifting assembly 7, and a safety distance is arranged between the lifting plate 9 and the bottom of the shock damper 5, so that the normal work of the shock damper 5 is not interfered.

[0070] The spring 44, the support rod 42 and the sleeve 41 in the buffer assembly 4 maintain the initial relative position, and the buffer assembly 4 bears the weight of the bearing plate 8 and the components above the bearing plate 8.

[0071] Overhaul preparation stage

[0072] The overhaul personnel drive the driving member 71 to rotate the worm 72, the worm 72 drives the worm gear 73 to rotate, the transmission module 77, the first bevel gear 74 and the second bevel gear 75 are driven, the screw rod 76 is matched with the threaded hole of the second bevel gear 75, and the screw rod 76 drives the bearing plate 8 to ascend along the axis of the screw rod 76.

[0073] When the bearing plate 8 ascends to the contact of the storage groove 91 of the lifting plate 9 and the bottom of the shock damper 5, the shock damper 5 is gradually separated from the connecting point of the mounting seat on the second wall body 2 through continuous ascending, until the weight of the shock damper 5 is completely borne (monitored through the pressure sensor or the travel switch).

[0074] The driving member 71 stops working, the self-locking characteristic of the worm 72, the worm gear 73 and the screw rod 76 locks the position of the bearing plate 8, at this time, the shock damper 5 is completely supported by the lifting plate 9, the wall connecting point is not stressed, and the overhaul state is entered.

[0075] Overhaul operation stage

[0076] The operator can safely disassemble the connecting bolts or pins of the shock damper 5 and the first wall body 1 and the second wall body 2, and perform appearance inspection, performance test or component replacement.

[0077] The baffle 81 is tightly attached to the side of the shock absorber 5 under the pulling force of the hard spring 82, and the buffer piece is adapted to the slight shaking of the shock absorber 5 through elastic deformation, so as to prevent the shock absorber 5 from falling or being damaged due to collision or accidental touch during the maintenance process.

[0078] Reset and acceptance stage

[0079] After the maintenance is completed, the driving part 71 is reversed, the lead screw 76 drives the bearing plate 8 to slowly descend until the shock absorber 5 is re-aligned with the wall body connection point, the maintenance personnel fasten the connecting bolts or pins of the shock absorber 5 and the wall body, and after confirming that the stress is uniform, the driving part 71 continues to descend to make the lifting plate 9 and the damper disengaged, and the initial position of the device is restored.

[0080] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
