Description

Technical Field

[0001] This invention relates to the field of seismic isolation bearing technology, specifically a modular and quick-assembly seismic isolation bearing installation structure. Background Technology

[0002] Seismic isolation bearings are crucial vibration-damping load-bearing components in building and bridge engineering. They primarily buffer external seismic loads, reduce vibration transmission effects, and ensure the stability and safety of the main structure. Currently, most conventional modular seismic isolation bearings on the market rely solely on a single spring or a simple rigid damping structure to achieve their vibration damping function. Their overall structural design is relatively simple, only achieving passive vibration damping of the foundation, lacking graded protection and adaptive pressure-stabilizing structural support. Conventional bearings exhibit poor buffering uniformity when facing small vibrations, are inconvenient to adaptively adjust support stiffness according to load changes, have weak vibration damping stability, and are prone to uneven stress and severe wear due to localized eccentric loading after long-term use.

[0003] Meanwhile, existing traditional seismic isolation bearings generally suffer from significant functional limitations. They only provide basic seismic isolation and lack displacement monitoring and early warning systems, as well as over-limit mechanical protection structures, resulting in an incomplete overall protection system. Under extreme conditions such as strong earthquakes and sudden overloads, the bearing displacement can easily exceed the standard damping range, failing to provide timely fault indications or limit and lock protection for the damping structure. This can easily lead to over-travel deformation, displacement, or even structural damage to the damping structure, significantly reducing the seismic isolation performance and service life of the bearings and directly affecting the seismic safety of the building's main structure.

[0004] Therefore, it is urgent to improve the aforementioned equipment in order to solve the problems mentioned above. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a modular and rapidly assembled vibration damping and isolation bearing installation structure. It has advantages such as air pressure adaptive pressure stabilization and vibration reduction, sensitive displacement conversion response, active fault warning, over-limit mechanical locking, and multi-level linkage protection. It achieves both stable vibration reduction in daily use and structural protection under extreme working conditions, effectively improving the overall stability and service life of the bearing.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a modular and rapid assembly seismic isolation bearing installation structure, comprising a bearing structure, a connecting sleeve disposed outside the bearing structure, and an elastic element. The bearing structure includes a lower connecting plate, a lower support seat, an upper connecting plate, and an upper support seat. An air chamber is provided inside the connecting sleeve. A floating structure for support is disposed outside the lower connecting plate and the upper connecting plate. An alarm structure is disposed outside the floating structure, and a protection structure is disposed outside the floating structure and is linked to the alarm structure. The floating structure includes multiple connecting ears fixedly connected to the outside of the lower connecting plate and the upper connecting plate, a slide fixedly connected to the outside of the connecting sleeve, a slider slidably connected to the inside of the slide, pins rotatably connected to the inside of multiple sets of connecting ears and configured as two sets, a first connecting rod and a second connecting rod rotatably connected to the outside of the two sets of pins, a piston cylinder fixedly connected to the inside of the slide, and a piston rod slidably passing through the inside of the piston cylinder. The alarm structure includes a mounting cylinder fixedly connected to one end of the piston rod and a housing fixedly connected to the outside of the slide block, a top rod slidably passing through the inside of the mounting cylinder, a proximity switch fixedly connected to one end of the top rod, a buffer spring fixedly connected between the mounting cylinder and the top rod, and a buzzer fixedly connected inside the housing.

[0007] Furthermore, the lower support is fixedly connected to the top of the lower connecting plate, the upper support is fixedly connected to the bottom side of the upper connecting plate, and the connecting sleeve is fitted over the lower and upper support. The air chamber inside the connecting sleeve is filled with pressure-stabilizing gas to cooperate with the floating structure to achieve adaptive pressure-stabilizing support of the support.

[0008] Furthermore, both ends of the two sets of pins are threaded with limit bolts, and the ends of the first and second connecting rods away from the connecting sleeve are rotatably connected to the outside of the slider. Through the linkage and hinge of the first and second connecting rods, the vertical compression displacement of the support is converted into horizontal sliding displacement.

[0009] Furthermore, the piston rod is fixedly assembled inside the slider, the piston rod slides through the inside of the piston cylinder, and a preload spring is fixedly connected between the piston rod and the inner wall of the piston cylinder. The preload spring is used to provide a reset preload force for the piston rod.

[0010] Furthermore, a valve pipe is fixedly connected to the top of the piston cylinder, and a gas supply pipe is fixedly connected to the top of the valve pipe. The end of the gas supply pipe extends into the gas chamber of the connecting sleeve, so that the piston cylinder and the gas chamber form a connected gas passage.

[0011] Furthermore, when the upper support and the lower support undergo relative compression displacement, the first connecting rod and the second connecting rod rotate synchronously and pull the slider and piston rod to slide outward, compressing the gas inside the piston cylinder, so that the gas is introduced into the gas chamber through the valve pipe and the gas supply pipe, thereby realizing the overall pressure stabilization, buffering and vibration isolation functions of the support.

[0012] Furthermore, the proximity switch is mounted on the end of the push rod, which is elastically slidably disposed inside the mounting cylinder and is elastically buffered and protected by the buffer spring. The buzzer is electrically connected to the proximity switch. When the piston rod exceeds its displacement range, it can trigger the proximity switch by linking the push rod, thereby driving the buzzer to activate the over-limit alarm.

[0013] Furthermore, the protective structure includes a transmission plate fixedly connected to the outside of the piston rod, a mounting base fixedly connected to the inner wall of the slide block, and a fixing block fixedly connected to the outside of the slide block. A square rod is slidably inserted inside the mounting base. A locking block that can clamp the piston rod is fixed to one end of the square rod, and an abutment ball is fixedly connected to the other end of the square rod. A return spring is fixedly connected between the abutment ball and the mounting base.

[0014] Furthermore, a guide rod is slidably inserted inside the fixed block, and a movable plate is fixedly connected to one end of the guide rod near the transmission plate. A wedge block is fixedly connected to the outer side of the movable plate, and a tension spring is fixedly connected between the movable plate and the fixed block. The movable plate is correspondingly arranged on the outer side of the transmission plate and can form an abutment fit with the transmission plate after displacement.

[0015] Furthermore, when the piston rod's shock-absorbing displacement exceeds the limit, the piston rod drives the transmission plate to move outward synchronously and abut against the sliding plate. The sliding plate drives the wedge block to move outward synchronously. The inclined surface of the wedge block presses against the ball, thereby driving the square rod to slide in conjunction, so that the locking clamping block clamps and limits the piston rod to achieve mechanical locking protection against displacement exceeding the limit. After the displacement is removed, the reset spring and tension spring realize the automatic reset of each structure.

[0016] Compared with the prior art, the present invention provides a modular and rapid assembly seismic isolation bearing installation structure, which has the following advantages: 1. In this invention, the support structure, connecting sleeve and floating structure work together in a coordinated manner. The lower support and upper support are compressed and generate relative displacement. The first connecting rod and the second connecting rod pull the slider and piston rod to slide, compressing the gas inside the piston cylinder. The gas is introduced into the gas chamber of the connecting sleeve through the valve pipe and the gas supply pipe, realizing the gas pressure adaptive stabilization and buffering, effectively improving the overall vibration reduction and isolation stability and load uniformity of the support.

[0017] 2. This invention achieves precise displacement conversion through a hinged transmission structure with a floating structure. Multiple sets of connecting ears and pins, along with limiting bolts, prevent detachment and stabilize the vertical vibration displacement of the support structure by converting it into the horizontal sliding of the piston rod. Combined with the elastic reset function of the pre-tightening spring inside the piston cylinder, it ensures that the structure returns to its original position quickly before and after vibration, effectively improving the problems of poor displacement response, delayed reset, and insufficient stability of traditional shock-absorbing supports.

[0018] 3. In this invention, when the piston rod slides beyond its range, it drives the mounting cylinder and the top rod to move synchronously, compressing the buffer spring and triggering a proximity switch signal; the buzzer inside the housing issues an over-limit alarm in real time, which can promptly report support overload and over-displacement faults, and effectively avoids rigid collisions in conjunction with the buffer spring, thereby improving the safety of equipment operation monitoring.

[0019] 4. In this invention, when the piston rod exceeds its displacement limit, it drives the transmission plate to push the moving plate, causing the wedge block to move synchronously and squeeze the ball, thereby driving the square rod inside the mounting base to slide, which in turn drives the locking block to clamp the limiting piston rod. This can instantly lock the structure, avoid excessive deformation and damage to the shock absorption structure, and provide extremely high protection reliability.

[0020] 5. This invention achieves a three-level linkage by using a floating structure for normal vibration reduction, an alarm structure for over-limit warning, and a protective structure for ultimate locking. During normal displacement, the air circuit is stabilized and buffered; when the limit is exceeded, a buzzer sounds to alert; and when the limit is reached, the locking clamps mechanically lock, thus achieving a buffering, warning, and locking protective effect. This ensures both daily vibration reduction and isolation performance and avoids the risk of structural failure under extreme working conditions. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1 to 7 This embodiment presents a modular, rapid-assembly seismic isolation bearing installation structure, comprising a bearing structure 1, a connecting sleeve 2 disposed outside the bearing structure 1, and elastic elements 3. The bearing structure 1 includes a lower connecting plate 11, a lower support seat 12, an upper connecting plate 13, and an upper support seat 14. An air chamber 21 is provided inside the connecting sleeve 2. A floating structure 4 for support is disposed outside the lower connecting plate 11 and the upper connecting plate 13, an alarm structure 5 is disposed outside the floating structure 4, and a protection structure 6 is disposed outside the floating structure 4 and is linked to the alarm structure 5. The elastic elements 3 are fixedly connected to the outside of the lower connecting plate 11 and the upper connecting plate 13 by bolts. By setting multiple sets of elastic elements 3 for bolt fixing, disassembly and assembly are convenient and the force is evenly distributed. At the same time, the floating structure 4, the alarm structure 5, and the protection structure 6 adopt a double-set symmetrical layout, so that the bearing structure 1 is subjected to balanced force and has strong resistance to eccentric loads, which greatly improves the overall seismic isolation stability and structural symmetry.

[0025] The lower support 12 is fixedly connected to the top of the lower connecting plate 11, and the upper support 14 is fixedly connected to the bottom of the upper connecting plate 13. The connecting sleeve 2 is fitted over the lower support 12 and the upper support 14. The air chamber 21 inside the connecting sleeve 2 is filled with a pressure-stabilizing gas to cooperate with the floating structure 4 to achieve adaptive pressure-stabilizing support of the support. By setting the lower support 12 and the upper support 14 to form an upper and lower aligned support structure, and with the pressure-stabilizing gas medium in the connecting sleeve 2 and its internal air chamber 21, the support stiffness can be adaptively adjusted, effectively buffering vertical loads and vibration impacts, and improving the bearing stability of the support.

[0026] To achieve the effect of adaptive buffering and voltage stabilization under vertical loads, please refer to [link / reference needed]. Figures 1 to 6In this embodiment, the floating structure 4 includes multiple connecting ears 43 fixedly connected to the outside of the lower connecting plate 11 and the upper connecting plate 13, a slide block 41 fixedly connected to the outside of the connecting sleeve 2, a slider 42 slidably connected inside the slide block 41, two sets of pins 44 rotatably connected to the inside of the multiple sets of connecting ears 43, a first connecting rod 46 and a second connecting rod 47 rotatably connected to the outside of the two sets of pins 44, a piston cylinder 48 fixedly connected inside the slide block 41, and a piston rod 49 slidably passing through the inside of the piston cylinder 48. By setting the floating structure 4 to use multiple connecting ears 43 in conjunction with a double-set connecting rod sliding structure, a linkage floating mechanism is formed by the slide block 41, slider 42, piston cylinder 48 and piston rod 49. The structure has smooth transmission, a large bearing area, and can stably absorb multi-directional vibration energy.

[0027] Both ends of the two sets of pins 44 are threaded with limit bolts 45. The ends of the first connecting rod 46 and the second connecting rod 47 away from the connecting sleeve 2 are rotatably connected to the outside of the slider 42. Through the linkage and hinge of the first connecting rod 46 and the second connecting rod 47, the vertical compression displacement of the support is converted into horizontal sliding displacement. The limit bolts 45 at both ends of the pins 44 are configured to prevent loosening and ensure that the hinge structure will not loosen during long-term operation. By utilizing the hinge lever principle of the first connecting rod 46 and the second connecting rod 47, the vertical displacement is efficiently converted into horizontal displacement, improving the utilization rate of the damping stroke.

[0028] Specifically, the piston rod 49 is fixedly mounted inside the slider 42, and slides through the piston cylinder 48. A preload spring 410 is fixedly connected between the piston rod 49 and the inner wall of the piston cylinder 48, providing a reset preload force for the piston rod 49. Through the sliding engagement between the piston rod 49 and the piston cylinder 48, combined with the continuous elastic preload force provided by the preload spring 410, the piston rod 49 can quickly and automatically reset after sliding, avoiding structural jamming or displacement, and ensuring stable and reliable operation of the shock absorption cycle.

[0029] It should be noted that a valve pipe 411 is fixedly connected to the top of the piston cylinder 48, and an air supply pipe 412 is fixedly connected to the top of the valve pipe 411. The end of the air supply pipe 412 extends into the air chamber 21 of the connecting sleeve 2, forming a connected air passage between the piston cylinder 48 and the air chamber 21. By constructing a sealed connected air passage between the piston cylinder 48 and the air chamber 21 through the valve pipe 411 and the air supply pipe 412, gas pressure regulation is achieved, forming a pneumatic pressure damping buffer system, making the vibration reduction process smoother and more continuous, and effectively reducing vibration peaks.

[0030] It is worth mentioning that when the upper support 14 and the lower support 12 undergo relative compression displacement, the first connecting rod 46 and the second connecting rod 47 rotate synchronously and pull the slider 42 and the piston rod 49 to slide outward, compressing the gas inside the piston cylinder 48. This allows the gas to enter the air chamber 21 through the valve pipe 411 and the air supply pipe 412, thereby achieving the overall pressure stabilization, buffering, and vibration isolation functions of the support. By utilizing the mechanical transmission of the support's pressure-bearing linkage rod in conjunction with pneumatic compression for air replenishment, dual energy dissipation through mechanical damping and pneumatic vibration reduction is achieved. This allows the support to adapt to vibration loads of varying sizes, providing excellent pressure stabilization and buffering effects and significantly improving its overall vibration isolation performance.

[0031] To monitor vibration damping displacement changes in real time and promptly capture the effects of bearing over-limit conditions, please refer to... Figures 3 to 5 In this embodiment, the alarm structure 5 includes a mounting cylinder 51 fixedly connected to one end of the piston rod 49, a housing 55 fixedly connected to the outside of the slide block 41, a top rod 52 slidably passing through the inside of the mounting cylinder 51, a proximity switch 54 fixedly connected to one end of the top rod 52, a buffer spring 53 fixedly connected between the mounting cylinder 51 and the top rod 52, and a buzzer 56 fixedly connected inside the housing 55. By arranging the alarm structure 5 synchronously with the piston rod 49, and through the mutual cooperation of the mounting cylinder 51, the top rod 52, the buffer spring 53, the proximity switch 54, and the buzzer 56, the alarm structure 5 can dynamically monitor the vibration-damping displacement in real time.

[0032] The proximity switch 54 is mounted on the end of the push rod 52, which is elastically slidably located inside the mounting cylinder 51 and is protected by a buffer spring 53. The buzzer 56 is electrically connected to the proximity switch 54. When the piston rod 49 exceeds its displacement range, it can trigger the proximity switch 54 by linking the push rod 52, driving the buzzer 56 to activate the over-limit alarm. By adopting an elastic buffer inductive triggering structure, the buffer spring 53 can protect the proximity switch 54 from rigid impact damage. The over-limit displacement automatically triggers the buzzer 56 to alarm, providing timely feedback on abnormal operating conditions of the support and improving the safety and early warning capabilities of the equipment.

[0033] To achieve the effect of instantaneous locking after exceeding limits and automatic structural reset after vibration disappearance, please refer to [link to relevant documentation]. Figures 3 to 6 In this embodiment, the protective structure 6 includes a transmission plate 61 fixedly connected to the outside of the piston rod 49, a mounting base 66 fixedly connected to the inner wall of the slide block 41, and a fixing block 62 fixedly connected to the outside of the slide block 41. A square rod 67 is slidably inserted inside the mounting base 66. A locking block 68 that can clamp the piston rod 49 is fixed at one end of the square rod 67, and an abutment ball 69 is fixedly connected at the other end of the square rod 67. A return spring 610 is fixedly connected between the abutment ball 69 and the mounting base 66.

[0034] A guide rod 63 slides through the fixed block 62. A movable plate 64 is fixedly connected to one end of the guide rod 63 near the transmission plate 61. A wedge block 65 is fixedly connected to the outer side of the movable plate 64. A tension spring 611 is fixedly connected between the movable plate 64 and the fixed block 62. The movable plate 64 is positioned on the outer side of the transmission plate 61 and can abut against the displaced transmission plate 61. By setting the guide rod 63, the movable plate 64, and the wedge block 65, a sloped extrusion transmission mechanism is formed. With the help of the tension spring 611, a normal return is achieved. The wedge transmission is stable in force and sensitive in response, providing precise and stable power transmission for mechanical locking actions.

[0035] Specifically, when the piston rod 49's vibration damping displacement exceeds the limit, the piston rod 49 drives the transmission plate 61 to move outward synchronously and abut against the sliding plate 64. The sliding plate 64 drives the wedge block 65 to move outward synchronously. The inclined surface of the wedge block 65 presses against the ball 69, thereby driving the square rod 67 to slide, so that the locking clamp 68 clamps and limits the piston rod 49 to achieve mechanical locking protection against displacement exceeding the limit. After the displacement is removed, the return spring 610 and tension spring 611 achieve automatic reset of each structure. By pressing against the ball 69 with the inclined surface of the wedge block 65, the piston rod 49 can be locked and limited instantly. Combined with the double spring reset structure, automatic reset is achieved, providing excellent extreme protection and reusability.

[0036] The working principle of the above embodiments is as follows: The present invention adopts a modular symmetrical assembly structure. The support structure 1 serves as the main load-bearing foundation and consists of a lower connecting plate 11, a lower support seat 12, an upper connecting plate 13, and an upper support seat 14, forming an upper and lower alignment support system. Multiple sets of elastic elements 3 are fixedly installed on the outside of the lower connecting plate 11 and the upper connecting plate 13 by bolts, realizing rapid assembly and uniform force support. The connecting sleeve 2 is sleeved on the outside of the lower support seat 12 and the upper support seat 14 of the support structure 1. Utilizing the pressure-stabilizing gas filled in the air chamber 21 inside the connecting sleeve 2, in conjunction with two sets of symmetrically arranged floating structures 4, alarm structures 5, and protection structures 6 on the outside, a vibration damping and isolation support integrating adaptive pressure stabilization and vibration reduction, displacement monitoring alarm, and over-limit mechanical locking is formed. Under normal vibration reduction conditions, when the support structure 1 is subjected to vibration load, causing the upper support 14 and the lower support 12 to undergo vertical relative compression displacement, the floating structure 4 forms an articulated transmission system through the lower connecting plate 11, multiple sets of connecting ears 43 on the outer side of the upper connecting plate 13, two sets of pins 44, the first connecting rod 46 and the second connecting rod 47. The limit bolts 45 at both ends of the pins 44 achieve anti-disengagement and limit, and the vertical compression displacement of the support is stably converted into the horizontal sliding motion of the slider 42 and the piston rod 49. The piston rod 49 slides outward to compress the medium inside the piston cylinder 48, and the gas inside the piston cylinder 48 is pressed into the air chamber 21 of the connecting sleeve 2 through the valve pipe 411 and the air supply pipe 412. With the elastic reset action of the pre-tightening spring 410 between the piston rod 49 and the piston cylinder 48, the combined damping of air pressure and mechanical elasticity is realized to achieve adaptive pressure stabilization and buffering, and effectively dissipate multi-directional vibration energy. During the vibration damping operation of the support, the alarm structure 5 synchronously monitors the displacement status in real time along with the floating structure 4. When the piston rod 49 slides, it synchronously drives the mounting cylinder 51 and the top rod 52 at the end to move as a whole. The buffer spring 53 between the mounting cylinder 51 and the top rod 52 is used to achieve elastic buffering, avoiding rigid impact damage to the proximity switch 54. When the vibration damping displacement of the piston rod 49 is within the standard range, the equipment buffers and dampes normally. When a strong earthquake causes the piston rod 49 to exceed the range, the proximity switch 54 at the end of the top rod 52 triggers a signal, activating the buzzer 56 inside the housing 55 to provide an audible and visual alarm, providing real-time feedback on the abnormal working condition of the support exceeding the limit, realizing early warning of faults, and improving the safety of equipment operation. Simultaneously with the over-limit alarm, the protection structure 6 activates the mechanical protection function. During the over-limit displacement of the piston rod 49, the transmission plate 61 fixed on the outside moves outward synchronously. The transmission plate 61 abuts against and pushes the outer moving plate 64 to slide, causing the wedge block 65 on the outside of the moving plate 64 to move synchronously. The inclined surface of the wedge block 65 presses against the abutment ball 69 at the end of the mounting base 66, thereby driving the square rod 67 inside the mounting base 66 to slide. This causes the locking clamp 68 at the end of the square rod 67 to quickly clamp the piston rod 49, mechanically locking and limiting the piston rod 49 to prevent the floating structure 4 from over-travel deformation, displacement, and structural damage. When the external vibration load disappears and the support force returns to a stable state, the compression displacement stops. Through the bidirectional elastic reset action of the return spring 610 between the abutment ball 69 and the mounting seat 66 in the protective structure 6, and the tension spring 611 between the moving plate 64 and the fixed block 62, in conjunction with the pre-tightening spring 410 of the floating structure 4, the wedge block 65, square rod 67, locking clamp block 68, piston rod 49 and each connecting rod structure are automatically reset, and the equipment returns to its initial state. It can then perform vibration reduction and isolation operations repeatedly.

[0037] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

The modular, rapid-assembly seismic isolation bearing installation structure according to claim 1, characterized in that: The protective structure (6) includes a transmission plate (61) fixedly connected to the outside of the piston rod (49), a mounting base (66) fixedly connected to the inner wall of the slide (41), and a fixing block (62) fixedly connected to the outside of the slide (41). A square rod (67) is slidably inserted inside the mounting base (66). A locking block (68) that can clamp the piston rod (49) is fixed at one end of the square rod (67). An abutment ball (69) is fixedly connected at the other end of the square rod (67). A return spring (610) is fixedly connected between the abutment ball (69) and the mounting base (66).

9. The modular, rapid-assembly seismic isolation bearing installation structure according to claim 8, characterized in that: A guide rod (63) is slidably inserted inside the fixed block (62). A movable plate (64) is fixedly connected to one end of the guide rod (63) near the transmission plate (61). A wedge block (65) is fixedly connected to the outside of the movable plate (64). A tension spring (611) is fixedly connected between the movable plate (64) and the fixed block (62). The movable plate (64) is correspondingly arranged on the outside of the transmission plate (61) and can form an abutment fit with the transmission plate (61) after displacement.

10. A modular, rapid-assembly seismic isolation bearing installation structure according to claim 9, characterized in that: When the piston rod (49) exceeds the damping displacement limit, the piston rod (49) drives the transmission plate (61) to move outward synchronously and abut against the sliding plate (64). The sliding plate (64) drives the wedge block (65) to move outward synchronously. The inclined surface of the wedge block (65) presses against the ball (69), thereby driving the square rod (67) to slide, so that the locking clamp (68) clamps the limiting piston rod (49) to achieve mechanical locking protection for displacement exceeding the limit. After the displacement is removed, the reset spring (610) and tension spring (611) realize the automatic reset of each structure.
