Description

Technical Field

[0001] This invention relates to the field of seismic isolation bearing technology, and more specifically, to an embedded limiting and locking rubber seismic isolation bearing. Background Technology

[0002] Passive structural control is one of the earliest and most widely applied seismic control methods both domestically and internationally. Currently, passive structural control has achieved significant results in both theory and application. Passive control does not require external energy; its principle involves installing seismic isolation or other energy dissipation devices in certain parts of the structure, reducing seismic response through self-energy dissipation. Due to its advantages such as low cost, simple construction, ease of maintenance, and no need for external energy support, passive control has received widespread attention in the civil engineering field and is widely used in practical engineering projects.

[0003] Rubber seismic isolation bearings, as a mature energy dissipation and vibration reduction technology, have been widely used in many practical engineering projects both domestically and internationally. When a structure is subjected to seismic forces, the rubber seismic isolation bearings move along with it. The relative movement of the rubber seismic isolation bearings dissipates energy, thereby reducing the seismic response.

[0004] Currently, most rubber seismic isolation bearings used in engineering are made of natural rubber or lead-core rubber. These bearings tend to move horizontally under minor earthquakes or significant wind loads. To ensure that the rubber seismic isolation bearings do not function under minor earthquakes and only activate at design limit values, a limiting and locking device is installed on the outside of the bearing. Could an embedded limiting and locking rubber seismic isolation bearing be designed? This embedded bearing would activate its limiting and locking device under minor earthquakes or wind loads, preventing the bearing from functioning, and only activate when the structural force reaches the limit value. When the locking device reaches its ultimate design value, the limiting locking device fails, and the rubber seismic isolation bearing enters the working state, achieving the purpose of seismic isolation and energy dissipation. The limiting locking device is embedded inside the bearing, which can prevent the limiting locking device from being damaged or corroded when it is installed externally. It can also avoid unnecessary casualties caused by the flying off of broken parts when the limiting locking device fails. How to design an embedded limiting locking rubber seismic isolation bearing to replace the rubber seismic isolation bearing, so that the rubber seismic isolation bearing does not move under small earthquakes and achieves the purpose of seismic isolation and energy dissipation when the design value is reached, has always been a difficult engineering problem to solve. Summary of the Invention

[0005] To address the problems mentioned in the background, this invention provides an embedded limiting and locking rubber seismic isolation bearing. When the device is subjected to minor earthquake or wind loads, the limiting and locking device activates, preventing the bearing from functioning. When the force on the structure reaches the limit design value of the limiting and locking device, the limiting and locking device breaks down, and the rubber seismic isolation bearing enters the working state, achieving the purpose of seismic isolation and energy dissipation. At the same time, it can prevent the limiting and locking device from being damaged or corroded when it is installed externally, and can also avoid unnecessary casualties caused by the flying off of broken parts when the limiting and locking device breaks down.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows:

[0007] An embedded limiting and locking rubber seismic isolation bearing includes an mounting plate. A seismic isolation bearing body is provided on one side of the mounting plate. A lower limiting and locking connector is fixedly connected to the bottom of the seismic isolation bearing body through a connecting plate. An upper limiting and locking connector is fixedly connected to the top of the seismic isolation bearing body through a connecting plate. A connecting block is fixedly connected inside the upper limiting and locking connector. A connecting cylinder that inserts into the inner wall of the seismic isolation bearing body is fixedly connected to the bottom of the connecting block. A screw extending into the connecting cylinder is threadedly connected to the inner wall of the connecting block. A compression ball is fixedly connected to one end of the screw. A telescopic ball that slides and connects to the outer wall of the compression ball is fitted to the outer wall of the connecting cylinder. A groove is provided at the connection between the inner wall of the seismic isolation bearing body and the telescopic ball.

[0008] The outer wall of the lower limiting lock connector is rotatably connected to a telescopic rod. The outer wall of the telescopic rod is slidably connected to a fixed rod that is rotatably connected to the outer wall of the upper limiting lock connector. The outer wall of the fixed rod is fixedly connected to a connecting air pipe. One end of the connecting air pipe is fixedly connected to a connecting pipe. The outer wall of the connecting pipe is provided with a duck-type nozzle. By using the embedded limiting lock rubber seismic isolation bearing, the rubber seismic isolation bearing does not move under small earthquakes, and achieves the purpose of seismic isolation and energy dissipation when the design value is reached. This fully utilizes the seismic isolation and energy dissipation function of the rubber seismic isolation bearing, ensuring the safety of the structure under seismic action. At the same time, it can prevent the limiting lock device from being damaged or corroded when it is installed externally. It can also avoid unnecessary casualties caused by the flying off of broken parts when the limiting lock device is damaged. This embedded limiting lock rubber seismic isolation bearing can be used for seismic isolation and vibration reduction control in building structures and bridge engineering.

[0009] Preferably, the top of the connecting block is provided with a protective cover, and the inner wall of the connecting block is provided with a cavity, and the inner wall of the seismic isolation support body and the connection part of the connecting cylinder are provided with an insertion hole.

[0010] Preferably, the main body of the seismic isolation bearing is made of thick rubber laminated rubber, and the length of the connecting cylinder is half the length of the insertion hole.

[0011] Preferably, the outer wall of the telescopic ball is fixedly connected to a sliding rod that is slidably connected to the inner wall of the connecting cylinder. A groove is provided at the connection point between the inner wall of the connecting cylinder and the sliding rod. A spring is fixedly connected to the outer wall of the sliding rod and to the inner wall of the connecting cylinder. After the connecting cylinder is inserted into the insertion hole, to improve the ease of engagement between the locking device and the base, the screw is first rotated, causing the extrusion ball to rotate and descend, simultaneously extruding the telescopic balls distributed around it. At the same time, the sliding rod slides along the inner wall of the groove. When the locking device is engaged... When the component is subjected to gravity, and the gravity exceeds the extreme value, it will drive the screw to descend under the action of gravity, causing the extrusion ball to continue to descend until the extrusion ball and the telescopic ball no longer contact each other. Under the reaction force of the stretched spring, the telescopic ball will slide out of the slot. At this time, the vibration isolation support begins to switch the force, achieving the purpose of vibration isolation and energy dissipation. At the same time, it can prevent the limit locking device from being damaged or corroded when it is installed externally, and can also avoid unnecessary casualties caused by the flying parts of the limit locking device when it is damaged.

[0012] Preferably, the telescopic ball is provided in four groups, and the positions of the four groups of telescopic balls are distributed in a ring about the central axis of the extrusion ball, and the slots are configured in a one-to-one correspondence with the telescopic balls.

[0013] Preferably, a hydraulic rod is rotatably connected to the outer wall of the mounting plate, and a connecting rod is slidably connected to the inner wall of the hydraulic rod. A rotating rod that engages with the outer wall of the connecting rod is rotatably connected to the outer wall of the limiting lock upper connector. A nut is provided on the outer wall of the rotating rod, and a bolt that slidably connects to the outer wall of the connecting rod is threaded onto the inner wall of the nut. A positioning groove is provided at the connection point between the outer wall of the connecting rod and the bolt. By setting the hydraulic rod, after the main body of the seismic isolation bearing is installed, the rotating rod and the connecting rod are brought into contact, and the bolt is rotated. Through the limiting action of the nut, the bolt is inserted into the positioning groove. The combination of the hydraulic rod and the connecting rod provides a left-right buffering and shock absorption effect on both sides of the main body of the seismic isolation bearing, achieving the effect of seismic reset on both sides of the base. It can realize the state locking control of the bearing to control the structural displacement response under small load conditions such as wind vibration or frequent earthquakes. When subjected to large load conditions such as rare earthquakes, the limiting lock material is destroyed, and the bearing enters the seismic isolation working state, reducing the structural acceleration response.

[0014] Preferably, the outer wall of the rotating rod and the connecting rod are provided with a connecting groove, and two sets of rotating rods are provided, the positions of the two sets of rotating rods being symmetrical about the central axis of the upper connecting member of the limiting lock.

[0015] Preferably, two sets of hydraulic rods and connecting rods are provided, and the positions of the two sets of hydraulic rods and connecting rods are symmetrical about the central axis of the seismic isolation bearing body.

[0016] Preferably, the connecting cylinder is inserted into the inner wall of the insertion hole as needed, and there are four sets of insertion holes, all of which are distributed on the surface of the seismic isolation bearing body.

[0017] Preferably, the duck-type nozzle is positioned above the upper connector of the limiting lock and is inclined. The mounting plate and the main body of the seismic isolation bearing are positioned on the same horizontal plane. The height of the duck-type nozzle is not higher than the height of the main body of the seismic isolation bearing. Preferably, the duck-type nozzle is positioned in any one of the following directions: horizontal, inclined, or vertical. With the duck-type nozzle, after the lower and upper connectors of the limiting lock are installed on the upper and lower parts of the seismic isolation bearing, the fixing rod is sleeved onto the outer wall of the telescopic rod. When the upper connector of the limiting lock is subjected to gravity compression, the fixing rod will slide along the outer wall of the telescopic rod, generating air pressure. At the same time, under the action of the connecting air pipe, the gas is delivered to the duck-type nozzle through the connecting pipe, achieving the effect of blowing off impurities on the surface of the upper connector of the limiting lock, reducing the interference of impurities on the main body of the seismic isolation bearing. When using machine vision and other technologies to monitor the deformation of the bearing, the airflow from the duck-type nozzle can clean the monitoring sensors, target points, etc., improving the accuracy of the monitoring results.

[0018] Compared with the prior art, the beneficial effects of this invention are as follows:

[0019] 1. This invention utilizes an embedded limiting and locking rubber seismic isolation bearing to prevent the rubber seismic isolation bearing from moving during minor earthquakes, and to achieve the purpose of seismic isolation and energy dissipation when the design value is reached. This fully utilizes the seismic isolation and energy dissipation function of the rubber seismic isolation bearing, ensuring the safety of the structure under seismic loading. At the same time, it can prevent the limiting and locking device from being damaged or corroded due to external installation, and can also avoid unnecessary casualties caused by the flying off of damaged parts when the limiting and locking device fails. This embedded limiting and locking rubber seismic isolation bearing can be used for seismic isolation and vibration reduction control in building structures and bridge engineering.

[0020] 2. This invention, through the setting of the duck-type nozzle, after the lower and upper limit locking connectors are installed on the upper and lower parts of the seismic isolation bearing body, respectively, the fixing rod is sleeved onto the outer wall of the telescopic rod. When the upper limit locking connector is subjected to gravity compression, it will drive the fixing rod to slide along the outer wall of the telescopic rod and generate air pressure. At the same time, under the action of the connecting air pipe, the gas is transported to the duck-type nozzle through the connecting pipe, achieving the effect of blowing off impurities on the surface of the upper limit locking connector, reducing the interference of impurities on the seismic isolation bearing body. When using machine vision and other technologies to monitor the deformation of the bearing, the airflow of the duck-type nozzle can clean the monitoring sensors, target points, etc., improving the accuracy of the monitoring results.

[0021] 3. This invention, through the setting of hydraulic rods, after the main body of the seismic isolation bearing is installed, brings the rotating rod into contact with the connecting rod, and rotates the bolt. Through the limiting action of the nut, the bolt is inserted into the positioning groove. The combination of hydraulic rods and connecting rods provides a left-right buffering and shock absorption effect on both sides of the main body of the seismic isolation bearing, achieving the effect of seismic reset on both sides of the base. It can achieve the state locking control of the bearing to control the structural displacement response under small load conditions such as wind vibration or frequent earthquakes. When subjected to large load conditions such as rare earthquakes, the limiting locking material is destroyed and the bearing enters the seismic isolation working state, reducing the structural acceleration response.

[0036] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0037] Example 1:

[0038] Please see Figures 1 to 12 This embodiment provides an embedded limiting and locking rubber seismic isolation bearing, including a mounting plate 1. A seismic isolation bearing body 2 is provided on one side of the mounting plate 1. The bottom of the seismic isolation bearing body 2 is fixedly connected to a lower limiting and locking connector 3 through a connecting plate. The top of the seismic isolation bearing body 2 is fixedly connected to an upper limiting and locking connector 4 through a connecting plate. A connecting block 5 is fixedly connected inside the upper limiting and locking connector 4. A connecting cylinder 6 that is inserted into the inner wall of the seismic isolation bearing body 2 is fixedly connected to the bottom of the connecting block 5. A screw 8 extending into the inner wall of the connecting cylinder 6 is threadedly connected to the inner wall of the connecting block 5. A compression ball 10 is fixedly connected to one end of the screw 8. A telescopic ball 11 that is slidably connected to the outer wall of the compression ball 10 is attached to the outer wall of the connecting cylinder 6. A slot 26 is provided at the connection between the inner wall of the seismic isolation bearing body 2 and the telescopic ball 11.

[0039] The outer wall of the lower limiting lock connector 3 is rotatably connected to a telescopic rod 16. The outer wall of the telescopic rod 16 is slidably connected to a fixed rod 15, which is rotatably connected to the outer wall of the upper limiting lock connector 4. The outer wall of the fixed rod 15 is fixedly connected to a connecting air pipe 17. One end of the connecting air pipe 17 is fixedly connected to a connecting pipe 18. The outer wall of the connecting pipe 18 is provided with a duck-type nozzle 19. By using the embedded limiting lock rubber seismic isolation bearing, the rubber seismic isolation bearing does not move under small earthquakes, and achieves the purpose of seismic isolation and energy dissipation when the design value is reached. This fully utilizes the seismic isolation and energy dissipation function of the rubber seismic isolation bearing, ensuring the safety of the structure under seismic action. At the same time, it can prevent the limiting lock device from being damaged or corroded when it is installed externally. It can also avoid unnecessary casualties caused by the flying off of damaged parts when the limiting lock device is damaged. This embedded limiting lock rubber seismic isolation bearing can be used for seismic isolation and vibration reduction control in building structures and bridge engineering.

[0040] like Figure 9 As shown, the top of the connecting block 5 is provided with a protective cover 9, and the inner wall of the connecting block 5 is provided with a cavity. The inner wall of the seismic isolation bearing body 2 and the connection part of the connecting cylinder 6 are provided with an insertion hole 7, which is conducive to the convenient change of the number of locking devices through the insertion hole 7 at the connection part of the inner wall of the seismic isolation bearing body 2 and the connecting cylinder 6.

[0041] like Figure 8 As shown, the main body 2 of the seismic isolation bearing is made of thick rubber laminated rubber. The length of the connecting cylinder 6 is half the length of the insertion hole 7. This design allows for the symmetrical installation and use of the lower limiting lock connecting piece 3 and the upper limiting lock connecting piece 4.

[0042] like Figure 11 and Figure 12 As shown, a sliding rod 12 is fixedly connected to the outer wall of the telescopic ball 11 and slidably connected to the inner wall of the connecting cylinder 6. A groove 13 is provided at the connection between the inner wall of the connecting cylinder 6 and the sliding rod 12. A spring 14 is fixedly connected to the outer wall of the sliding rod 12 and fixedly connected to the inner wall of the connecting cylinder 6. After the connecting cylinder 6 is inserted into the insertion hole 7, in order to improve the effect of convenient locking between the locking device and the base, the screw 8 is first rotated to drive the extrusion ball 10 to rotate and descend, and to simultaneously extrude the telescopic balls 11 distributed around it. At the same time, the sliding rod 12 is driven to slide along the inner wall of the groove 13. When locking... When the upper connector is subjected to gravity, and the gravity exceeds the extreme value, it will drive the screw 8 to descend under the action of gravity, and cause the extrusion ball 10 to continue to descend until the extrusion ball 10 and the telescopic ball 11 no longer contact each other. Under the reaction action of the spring 14 being stretched, the telescopic ball 11 will slide out of the slot 26. At this time, the vibration isolation support begins to switch the force, achieving the purpose of vibration isolation and energy dissipation. At the same time, it can prevent the limit locking device from being damaged or corroded when it is installed externally, and can also avoid unnecessary casualties caused by the flying off of damaged parts when the limit locking device is damaged.

[0043] like Figure 11 As shown, there are four sets of telescopic balls 11. The positions of the four sets of telescopic balls 11 are arranged in a ring about the central axis of the compression ball 10, and the slots 26 are arranged in a one-to-one correspondence with the telescopic balls 11. This is conducive to achieving the effect of stable locking connection of the locking device in the seismic isolation support by setting four sets of telescopic balls 11 whose positions are arranged in a ring about the central axis of the compression ball 10.

[0044] like Figures 3-4As shown, a hydraulic rod 20 is rotatably connected to the outer wall of the mounting plate 1, and a connecting rod 21 is slidably connected to the inner wall of the hydraulic rod 20. A rotating rod 22, which engages with the outer wall of the connecting rod 21, is rotatably connected to the outer wall of the limiting lock upper connecting piece 4. A nut 23 is provided on the outer wall of the rotating rod 22, and a bolt 24, which is slidably connected to the outer wall of the connecting rod 21, is threaded onto the inner wall of the nut 23. A positioning groove 25 is provided at the connection between the outer wall of the connecting rod 21 and the bolt 24. Through the setting of the hydraulic rod 20, after the seismic isolation bearing body 2 is installed, the rotating rod 22 and the connecting rod 24 are connected. When the connecting rods 21 come into contact and the bolt 24 is rotated, the bolt 24 is inserted into the positioning groove 25 by the limiting action of the nut 23. This combination of hydraulic rod 20 and connecting rod 21 provides a left and right buffering and damping effect on both sides of the seismic isolation bearing body 2, achieving the effect of seismic reset on both sides of the base. It can achieve the state locking control of the bearing to control the structural displacement response under small load conditions such as wind vibration or frequent earthquakes. When subjected to large load conditions such as rare earthquakes, the limiting locking material is destroyed and the bearing enters the seismic isolation working state, reducing the structural acceleration response.

[0045] like Figure 4 As shown, a connecting groove is provided at the connection point between the outer wall of the rotating rod 22 and the connecting rod 21. There are two sets of rotating rods 22. The positions of the two sets of rotating rods 22 are symmetrical about the central axis of the upper connecting member 4 of the limit lock. This facilitates the pre-connection and installation of the connecting rod 21 by providing a connecting groove at the connection point between the outer wall of the rotating rod 22 and the connecting rod 21.

[0046] like Figure 1 and Figure 2 As shown, two sets of hydraulic rods 20 and connecting rods 21 are provided. The positions of the two sets of hydraulic rods 20 and connecting rods 21 are symmetrical about the central axis of the seismic isolation bearing body 2. This is beneficial to achieve the effect of automatic hydraulic reset of the forces on the left and right sides of the seismic isolation bearing body 2 by setting two sets of hydraulic rods 20 and connecting rods 21 with their positions symmetrical about the central axis of the seismic isolation bearing body 2.

[0047] like Figure 7 As shown, the connecting cylinder 6 is inserted into the inner wall of the insertion hole 7 as needed. There are four sets of insertion holes 7, and the four sets of insertion holes 7 are distributed on the surface of the seismic isolation bearing body 2. This facilitates the convenient adjustment and installation of the number of connecting cylinders 6 by setting the insertion holes 7 evenly distributed on the surface of the seismic isolation bearing body 2.

[0048] like Figure 5As shown, the duck-type nozzle 19 is positioned above the upper connecting member 4 of the limit lock, and the duck-type nozzle 19 is inclined. The mounting plate 1 and the main body 2 of the seismic isolation bearing are set on the same horizontal plane. The setting height of the duck-type nozzle 19 is not higher than the setting height of the main body 2 of the seismic isolation bearing. The setting direction of the duck-type nozzle 19 can be any one of horizontal, inclined, or vertical orientations. This orientation allows for the adjustment and cleaning of dust from different directions. Furthermore, the duck-type nozzle 19's position above the upper connecting member 4 of the limit lock enables the pneumatic blowing off of impurities on the upper connecting member 4, thus improving the conversion of mechanical energy generated by the seismic base. With the duck-type nozzle 19 installed, after the lower limiting lock connector 3 and the upper limiting lock connector 4 are installed on the upper and lower parts of the seismic isolation bearing body 2 respectively, the fixing rod 15 is sleeved onto the outer wall of the telescopic rod 16. When the upper limiting lock connector 4 is subjected to gravity compression, the fixing rod 15 will slide along the outer wall of the telescopic rod 16 and generate air pressure. At the same time, under the action of the connecting air pipe 17, the gas is transported to the duck-type nozzle 19 through the connecting pipe 18, so as to blow off the impurities on the surface of the upper limiting lock connector 4, reduce the interference of impurities on the seismic isolation bearing body 2, and when the deformation of the bearing is monitored by machine vision and other technologies, the airflow of the duck-type nozzle can clean the monitoring sensors, target points, etc., and improve the accuracy of the monitoring results.

[0049] Working principle:

[0050] like Figures 1-12 As shown, when this seismic base is used, firstly, the embedded limiting and locking rubber seismic isolation bearing is used to prevent the rubber seismic isolation bearing from moving under small earthquakes. When the design value is reached, it plays the role of seismic isolation and energy dissipation, giving full play to the seismic isolation and energy dissipation function of the rubber seismic isolation bearing, ensuring the safety of the structure under seismic action. At the same time, it can prevent the limiting and locking device from being damaged or corroded when it is installed externally. It can also avoid unnecessary casualties caused by the flying off of broken parts when the limiting and locking device is damaged. This embedded limiting and locking rubber seismic isolation bearing can be used for seismic isolation and vibration reduction control in building structures and bridge engineering.

[0051] Next, by setting the duck nozzle 19, after the lower limiting lock connector 3 and the upper limiting lock connector 4 are respectively installed on the upper and lower parts of the seismic isolation bearing body 2, the fixing rod 15 is sleeved onto the outer wall of the telescopic rod 16. When the upper limiting lock connector 4 is squeezed by gravity, the fixing rod 15 will slide along the outer wall of the telescopic rod 16 and generate air pressure. At the same time, under the action of the connecting air pipe 17, the gas is transported to the duck nozzle 19 through the connecting pipe 18, so as to achieve the effect of blowing off the impurities on the surface of the upper limiting lock connector 4 by the gas, reducing the interference effect of impurities on the seismic isolation bearing body 2.

[0052] Next, by setting the hydraulic rod 20, after the seismic isolation bearing body 2 is installed, the rotating rod 22 is brought into contact with the connecting rod 21, and the bolt 24 is rotated and, through the limiting action of the nut 23, the bolt 24 is inserted into the positioning groove 25. The combination of the hydraulic rod 20 and the connecting rod 21 provides a left and right buffering and shock absorption effect on both sides of the seismic isolation bearing body 2, achieving the effect of seismic reset on both sides of the base. It can realize the state locking control of the bearing to control the structural displacement response under small load conditions such as wind vibration or frequent earthquakes. When subjected to large load conditions such as rare earthquakes, the limiting locking material is destroyed and the bearing enters the seismic isolation working state, reducing the structural acceleration response.

[0053] Finally, after inserting the connecting cylinder 6 into the socket 7, in order to improve the convenient locking connection between the locking device and the base, first rotate the screw 8 to drive the compression ball 10 to rotate and descend, and simultaneously compress the telescopic balls 11 distributed around it. At the same time, it drives the sliding rod 12 to slide along the inner wall of the slide groove 13. When the locking upper connecting part is subjected to gravity, and the gravity exceeds the extreme value, it will drive the screw 8 to descend under the action of gravity, and cause the compression ball 10 to continue to descend until the compression ball 10 and the telescopic ball 11 no longer contact each other. Under the reaction action of the spring 14 being stretched, the telescopic ball 11 will slide out of the slot 26. At this time, the vibration isolation support begins to switch the force, achieving the purpose of vibration isolation and energy dissipation. At the same time, it can prevent the limit locking device from being damaged or corroded when installed externally, and can also avoid unnecessary casualties caused by the flying parts of the limit locking device when it is damaged.
