Description

Technical Field

[0001] This utility model belongs to the field of building construction, and specifically relates to a leveling device for a seismic isolation bearing positioning plate. Background Technology

[0002] Seismic isolation bearings are key components used in earthquake resistance of building structures. They are typically installed between the foundation and the superstructure. Their core function is to isolate and dissipate seismic energy through their elastic deformation and energy dissipation characteristics, thereby significantly reducing earthquake damage to buildings. They are mostly made of laminated materials such as rubber and steel plates, possessing good vertical load-bearing capacity to stably support the weight of the building. Simultaneously, they have a certain degree of horizontal flexibility, allowing for reasonable structural displacement during an earthquake. Acting like a "buffer," they keep the superstructure relatively stable during earthquakes, reducing the risk of cracking and collapse caused by severe vibrations, effectively improving the seismic performance of buildings. Currently, they are widely used in bridges, high-rise buildings, and the preservation of ancient buildings.

[0003] The prior art patent application (application number 202420151980.4) entitled "A Seismic Isolation Bearing Installation and Adjustment Device" includes a base plate. An adjustment component is located at the top of the base plate, and the adjustment component is connected to a mounting base. The top surface of the mounting base has an installation groove for installing the seismic isolation bearing. Clamping components for fixing the seismic isolation bearing are provided on both opposite inner sidewalls of the installation groove. The two clamping components are symmetrically arranged. An observation component for observing whether the seismic isolation bearing is level is located at the bottom of the mounting base. The device is placed in a pier, and the seismic isolation bearing is fixed in the installation groove. The observation component contains liquid and has graduations. The observation component determines whether the seismic isolation bearing is level. If the seismic isolation bearing is not level, the adjustment component can be used to adjust the seismic isolation bearing until the liquid graduations in the observation component are the same, at which point the seismic isolation bearing is level.

[0004] However, while the threaded rod is used to finely adjust the levelness of the seismic isolation bearing to ensure it is in a horizontal state, laying the foundation for the building's stability and seismic resistance, the threaded rod lacks an effective locking mechanism. Under the influence of external factors such as strong winds and vibrations of internal building equipment, it is prone to rotation, causing the levelness of the seismic isolation bearing to deviate and weakening the seismic isolation effect. In addition, in terms of limiting the seismic isolation bearing, the device only relies on the spring to compress the inclined plate, so that the inclined plate covers the protrusion of the seismic isolation bearing. However, the force applied by the spring is limited. After encountering large vibrations or long-term use, the spring fatigues and deforms, making it difficult to continuously provide sufficient pressure to the inclined plate. As a result, the inclined plate cannot fit tightly against the protrusion of the seismic isolation bearing, and the limiting effect of the seismic isolation bearing decreases. Therefore, we propose a leveling device for the positioning plate of the seismic isolation bearing that is easy to operate. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects in the prior art and provide a leveling device for a seismic isolation bearing positioning plate.

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and preferred embodiments.

[0026] Figure 1-5 A leveling device for a seismic isolation bearing positioning plate is shown, comprising a base 100, a base plate 110 disposed on the base, and a mounting seat 200 disposed on the base plate; the base plate is provided with a plurality of adjustment structures; in this embodiment, there are four, which are respectively fixed at the middle position of the four sides of each base plate 110.

[0027] The adjustment structure includes a motor 120 mounted on the base plate 110 and a threaded rod 121 connected to the output end of the motor; the top of the threaded rod 121 is connected to the mounting base 200 via a connecting plate 130, and a locking unit is provided at the bottom of the threaded rod. Figure 3 (as shown).

[0028] The locking unit includes two V-shaped locking blocks 150 symmetrically arranged on the outside of the threaded rod, a mounting plate connected to the V-shaped locking blocks 150, and a bidirectional screw 141 threadedly connected to the mounting plate. A damping rubber pad 151 is provided at the contact end between the V-shaped locking blocks 151 and the threaded rod 121. The other side of the two V-shaped locking blocks 150 can be hinged, or a locking unit can be provided for easy adjustment.

[0029] The following is a detailed explanation: Figure 1-3As shown, a base plate 110 is fixedly connected to the top of the base 100, and four motors 120 are fixedly connected to the bottom of the base plate 110. The top end of the power output shaft of the motor 120 passes through the base plate 110 and extends to the top of the base 100. A threaded rod 121 is fixedly connected to the top end of the power output shaft of the motor 120. A connecting plate 130 is screwed to the outer side of the threaded rod 121. The connecting plate 130 is hinged to the mounting base 200. Two V-shaped locking blocks are provided at the bottom of the threaded rod 121. A mounting plate 140 is fixedly connected to one side of the V-shaped locking blocks, and the mounting plates 140 are evenly distributed. A bidirectional screw 141 is rotatably connected between the inner sides of the two mounting plates 140. One end of the bidirectional screw 141 passes through one side of the mounting plate 140 and extends to the outer side of the mounting plate 140. A damping rubber pad 151 is bonded to one side of the locking block 150. The damping rubber pad 151 is in contact with the threaded rod 121. After the leveling is completed, the threaded rod 121 needs to be locked and fixed. At this time, the double-acting screw 141 is rotated. Because it is a double-acting screw structure, when the screw rotates, the V-shaped locking blocks 150 on both sides will move towards each other along the double-acting screw 141 under the action of the thread. When the V-shaped locking block 150 approaches the threaded rod 121, the damping rubber pad 151 bonded to one side is in close contact with the threaded rod 121. As the V-shaped locking block 150 moves closer, the damping rubber pad 151 will apply a large frictional force to the threaded rod 121. With the elasticity and damping characteristics of the rubber, the threaded rod 121 is firmly locked and prevented from rotating due to external factors.

[0030] In summary, it is essential to maintain the horizontal position of the seismic isolation bearings after they have been adjusted to ensure that they can stably perform their seismic resistance function in subsequent use.

[0031] Figure 4-6 The mounting base 200 is shown to have a vibration isolation seat 210 inside; the mounting base 200 has a cavity for accommodating the vibration isolation seat 210; the mounting base has mounting grooves 220 on both sides; and each mounting groove 220 has a snap-fit ​​unit inside it.

[0032] The snap-fit ​​unit includes a movable plate 240 disposed in the mounting groove, a power unit disposed on the side of the movable plate away from the vibration isolation seat, and a connecting unit disposed on the side of the movable plate close to the vibration isolation seat.

[0033] The power unit includes at least one or more combinations of magnetic components, spring components, and friction components;

[0034] The connecting unit includes an inclined panel 250 connected to the movable plate and a pull plate 251 disposed on the inclined panel; the contact surface between the inclined panel 250 and the vibration isolation seat 210 is an inclined surface.

[0035] The magnetic component includes a pair of repulsive magnets connected to the outer wall of the mounting groove and the movable plate, respectively; the pair of repulsive magnets includes a first repulsive magnet 221 connected to the outer wall of the mounting groove and a second repulsive magnet 241 connected to the movable plate.

[0036] The spring body component includes one or more spring bodies 243 that are respectively connected to the outer wall of the mounting groove and the movable plate.

[0037] The friction body component includes a friction body 230 and a friction sleeve 242, which are respectively connected to the outer wall of the mounting groove and the movable plate; the friction body passes through the movable plate and contacts the friction sleeve.

[0038] Specifically, in this embodiment, the mounting base 200 is located above the base 100. A vibration isolation seat 210 is placed at the bottom of the inner cavity of the mounting base 200. Two mounting slots 220 are formed inside the mounting base 200. A first repulsive magnet 221 is fixedly connected to the inner wall of the mounting slot 220. A friction plate 230 is fixedly connected to the inner wall of the mounting slot 220. A movable plate 240 is slidably connected to the outer side of the friction plate 230. A second repulsive magnet 241 is fixedly connected to one side of the movable plate 240. A friction sleeve 242 is fixedly connected to one side of the movable plate 240. One side of the friction plate 230 penetrates the movable plate 240, and the friction plate 230 contacts the friction sleeve 242. Two spring bodies 243 are fixedly connected to one side of the movable plate 240, and an inclined plate 250 is fixedly connected to the other side of the movable plate 240. One side of the inclined plate 250 passes through the mounting groove 220 and extends into the inner cavity of the mounting base 200, and the inclined plate 250 is engaged with the vibration isolation base 210. A lever 251 is fixedly connected to the top of the inclined plate 250, and the top of the lever 251 passes through the mounting groove 220 and extends into the top of the mounting base 200. When installing the vibration isolation base 210, it is slowly placed at the bottom of the inner cavity of the mounting base 200. Since the top of the inclined plate 250 is inclined, when the vibration isolation base 210 falls, its bottom first contacts the top of the inclined plate 250, and as it continues to move downward, it contacts the inclined plate 250. Pressure is applied at 50. Under this pressure, the inclined plate 250 moves inward toward the mounting groove 220, thereby driving the movable plate 240 connected to it to move synchronously. At this time, the first repulsive magnet 221 in the mounting groove 220 and the second repulsive magnet 241 on the movable plate 240 generate a repulsive magnetic force due to the repulsion of like poles, providing an auxiliary thrust for the movement of the movable plate 240. At the same time, the spring body 243 is in a compressed state, further enhancing the power of the movable plate 240 to move inward. Under the combined action of the pressure applied by the vibration isolation seat 210 itself, the magnetic force, and the spring force, the movable plate 240 drives the inclined plate 250 to continuously approach the vibration isolation seat 210 until the inclined plate 250... The vibration isolator 210 is tightly engaged with the mounting base 200, thus securing the vibration isolator 210 within the mounting base 200. During this process, the friction sleeve 242 and the friction plate 230 come into contact with each other, providing damping for the movement of the moving plate 240 through friction, preventing the inclined plate 250 from moving too quickly and causing impact, while also enhancing the structural stability after engagement. When disassembling, the lever 251 is moved laterally, causing the lever 251 to move the inclined plate 250, thus removing the inclined plate 250 from limiting the vibration isolator 210, after which the vibration isolator 210 can be disassembled. In summary, the technical solution of this application can prevent the inclined plate from moving too quickly and causing impact, while also enhancing the structural stability after engagement.

[0039] In summary, the seismic isolation bearing positioning plate of this application is equipped with an independent locking unit using a leveling device. After the leveling adjustment is completed, rotating the bidirectional screw will cause the V-shaped locking blocks on both sides to move towards each other along the bidirectional screw under the action of the thread, firmly locking the threaded rod and preventing it from rotating due to external factors. This ensures that the seismic isolation bearing is stably maintained in the leveling state that has been adjusted, and ensures that the seismic isolation bearing can stably play its seismic resistance role in subsequent use.

[0040] As a preferred embodiment, a snap-fit ​​unit is provided between the seismic isolation seat and the mounting seat. The snap-fit ​​unit contains multiple power units, including magnetic components, spring components, and friction components, which can enhance the structural stability of the seismic isolation seat after snap-fit. When disassembling, the lever is moved laterally, causing the lever to move the inclined panel, so that the inclined panel can remove the restriction on the seismic isolation seat, and then the seismic isolation seat can be disassembled.

[0041] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
