Description

Technical Field

[0001] This invention relates to the field of building seismic isolation technology, specifically to an adaptive support structure for a large deformation electromechanical seismic isolation module. Background Technology

[0002] Seismic isolation technology effectively absorbs seismic energy and reduces damage to the superstructure by installing a seismic isolation layer between the superstructure and the foundation. In seismically isolated buildings, pipes passing through the isolation layer need to use flexible connections to accommodate horizontal deformation of the isolation layer. However, when long-distance flexible isolation hoses are installed horizontally, their low stiffness can cause sagging in the middle, leading to stress concentration at the flange connections and severely affecting the service life of the isolation modules.

[0003] To address the sagging issue of long-distance seismic isolation flexible tubes, existing technologies often employ suspension chains or rods to suspend and support them. Specifically, a sliding rail is installed beneath the building structure, with the upper end of the suspension chain or rod slidingly engaging with the rail, while the lower end suspends the seismic isolation flexible tube. This allows the tube to move horizontally with the isolation layer, while simultaneously preventing sagging in the middle.

[0004] However, this suspended support structure has a significant drawback: the upper end of the suspension chain or rod needs to slide on a rail. During an earthquake, the isolation layer undergoes horizontal displacement, and the suspension chain or rod moves along the rail. Since the direction of the rail is fixed (usually a unidirectional rail), while the direction of horizontal displacement during an earthquake is random and multidirectional, when the actual displacement direction of the isolation layer is inconsistent with the direction of the rail, the suspension chain or rod will exert a constraint force on the flexible hose, forcing the hose to move along the rail direction instead of its own free deformation trajectory. This constraint restricts the free deformation of the isolation hose, preventing it from fully utilizing its isolation capacity, and may even generate additional stress at the connection between the hose and the suspension chain, leading to damage to the hose or connector.

[0005] Therefore, an adaptive support structure for a large deformation electromechanical vibration isolation module is proposed here. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the purpose of this invention is to provide an adaptive support structure for a large-deformation electromechanical vibration isolation module that can prevent the vibration isolation hose from sagging while allowing the hose to deform freely in any horizontal direction without being restricted by the direction of the slide rail.

[0007] The technical solution adopted by this invention to solve its technical problem is: An adaptive support structure for a large deformation electromechanical vibration isolation module includes a support platform with a hanger rod installed on it. The upper end of the hanger rod is used for fixed connection to the building structure. The structure also includes a first vibration isolation hose for connecting to pipes in the isolation zone and a second vibration isolation hose for connecting to pipes in the non-isolation zone. The first and second vibration isolation hoses are connected by a connecting elbow. A trolley and multiple support components are arranged above the support platform. The trolley and support components are slidably connected to the upper surface of the support platform by ball bearings and can slide freely in the horizontal direction. The first and second vibration isolation hoses are respectively connected to their corresponding support components, and the connecting elbow is supported on the trolley.

[0008] As a preferred embodiment, a further technical solution of the present invention is: Preferably, the support includes a first arc-shaped block and a second arc-shaped block hinged to the first arc-shaped block, and the first and second vibration isolation hoses are respectively accommodated between the first and second arc-shaped blocks of the corresponding support.

[0009] Preferably, the support member is provided with a limiting mechanism for locking or unlocking the first arc-shaped block and the second arc-shaped block; the limiting mechanism includes a mounting block fixed to the bottom surface of the second arc-shaped block and a mounting groove formed on the first arc-shaped block, the mounting block and the mounting groove being inserted into each other; a through groove is formed inside the mounting block, and two sliding plates are slidably connected in the through groove, and a locking block is fixed on the side of the two sliding plates that are far apart from each other, the bottom surface of the locking block being inclined; a telescopic spring is provided in the through groove between the two sliding plates, and the telescopic spring is always in a compressed state; a locking groove is formed on the first arc-shaped block, and the locking block and the locking groove are engaged.

[0010] Preferably, the inclined surface of the locking block faces the opening direction of the mounting groove. When the mounting block is inserted into the mounting groove, the inclined surface contacts the edge of the mounting groove and pushes the locking block to retract into the groove.

[0011] Preferably, a push rod is slidably connected in the slot, with one end of the push rod abutting against one side of the card block and the other end protruding from the side of the first arc-shaped block.

[0012] Preferably, a limiting groove is formed on the inner wall at the bottom of the slot, and a limiting block is fixed on the outer surface of the push rod. The limiting block is slidably connected inside the limiting groove to guide and limit the movement of the push rod.

[0013] Preferably, both the first arc-shaped block and the second arc-shaped block have rubber pads inside.

[0014] Preferably, a side plate is fixed to one side of the trolley, a return spring is fixed to one side of the side plate, and the other end of the return spring is fixed to the rod.

[0015] Preferably, the trolley is equipped with an elastic buckle, and the connecting elbow is fastened to the trolley by the elastic buckle.

[0016] Preferably, a limit block is fixed at the edge of the upper surface of the support platform. The height of the limit block is higher than the rolling surface of the ball, which is used to limit the sliding range of the trolley and the support and prevent them from slipping off the support platform.

[0017] The present invention, which adopts the above technical solution, has the following prominent features compared with the prior art: This invention employs a ball-bearing sliding connection, allowing the support and trolley to slide freely in any horizontal direction on the upper surface of the support platform, unrestricted by the direction of a fixed slide rail. During an earthquake, the seismic isolation hose can move along its own free deformation trajectory, completely eliminating the constraint force generated by the suspension chain or rod, thus fully utilizing the seismic isolation capability of the isolation module. Simultaneously, the support supports the seismic isolation hose from below, effectively preventing sagging due to its own weight during horizontal installation of long-distance hoses and avoiding stress concentration at flange connections. Furthermore, the limiting mechanism achieves rapid locking and unlocking of the support through the engagement of a locking block and a locking slot; simply press the lever to unlock, allowing for tool-free installation and replacement of the seismic isolation hose, ensuring convenient operation and reliable locking. The elastic buckle on the trolley reliably engages the connecting elbow, preventing it from detaching during an earthquake. The return spring pulls the trolley and connecting elbow back to their initial positions after an earthquake, achieving automatic reset. The limiting block effectively restricts the sliding range of the trolley and support, preventing them from slipping off the support platform. Attached Figure Description

[0020] The present invention will be further illustrated below with reference to specific embodiments. The purpose of this illustration is solely to provide a better understanding of the invention. Therefore, the examples given do not limit the scope of protection of the present invention.

[0021] like Figures 1 to 3 As shown in the figure, this embodiment provides an adaptive support structure for a large deformation electromechanical vibration isolation module, including a support platform 1. A hanger 101 is installed on the support platform 1, and the upper end of the hanger 101 is fixedly connected to the ceiling of the building in the vibration isolation zone via expansion bolts or embedded parts, for suspending the support platform 1 below the building structure. It also includes a first vibration isolation hose 4 for connecting to pipelines in the vibration isolation zone and a second vibration isolation hose 5 for connecting to pipelines in the non-vibration isolation zone. The first vibration isolation hose 4 and the second vibration isolation hose 5 are connected by a connecting elbow 6. The first vibration isolation hose 4 and the pipelines in the vibration isolation zone, the second vibration isolation hose 5 and the pipelines in the non-vibration isolation zone, and the connecting elbow 6 and the first and second vibration isolation hoses 5 are all connected by flange structures. A trolley 7 and multiple support members 3 are provided above the support platform 1. The trolley 7 and the support members 3 are slidably connected to the upper surface of the support platform 1 by ball bearings and can slide freely in the horizontal direction. The first vibration isolation hose 4 and the second vibration isolation hose 5 are respectively connected to the corresponding support members 3, and the connecting elbow 6 is supported on the trolley 7. In this embodiment, the support platform 1 is formed by welding steel.

[0022] The support member 3 includes a first arc-shaped block 301 and a second arc-shaped block 302 hinged to the first arc-shaped block 301. Specifically, the second arc-shaped block 302 is hinged to one side of the first arc-shaped block 301 and can be opened, closed, and rotated around the hinge axis. The first vibration isolation hose 4 and the second vibration isolation hose 5 are respectively accommodated between the first arc-shaped block 301 and the second arc-shaped block 302 of the corresponding support member 3.

[0023] In this embodiment, the first arc-shaped block 301 and the second arc-shaped block 302 are made of cast aluminum alloy. Both the first arc-shaped block 301 and the second arc-shaped block 302 have rubber pads 304 inside to increase friction with the outer wall of the hose and provide cushioning protection. The first vibration-damping hose 4 and the second vibration-damping hose 5 are respectively accommodated between the first arc-shaped block 301 and the second arc-shaped block 302 of the corresponding support member 3. When the second arc-shaped block 302 is engaged, the first arc-shaped block 301 and the second arc-shaped block 302 together form a circular or elliptical clamping space that matches the outer diameter of the hose, thus radially constraining the hose.

[0024] Specifically, the ball bearings include multiple first ball bearings 303 mounted on the bottom surface of the first arc-shaped block 301, which can roll freely. The first ball bearings 303 roll and support the upper surface of the support platform 1, allowing the support member 3 to slide freely on the support platform 1 in any horizontal direction; it also includes multiple second ball bearings 702 mounted on the bottom surface of the trolley 7, which roll and support the upper surface of the support platform 1.

[0025] A side plate 701 is fixed to one side of the trolley 7, extending along the sliding direction of the trolley 7. A return spring 8 is fixed to one side of the side plate 701. The return spring 8 is a stainless steel spring, and its spring constant is selected based on the weight of the seismic isolation module and the design deformation. The other end of the return spring 8 is fixed to the hanger rod 101. The return spring 8 applies a return force to the trolley 7 toward its initial position, keeping the connecting elbow 6 in a predetermined position under non-earthquake conditions and assisting the trolley 7 in returning to its original position after an earthquake.

[0026] Reference Appendix Figure 4 The support member 3 is provided with a limiting mechanism 2 for locking or unlocking the first arc-shaped block 301 and the second arc-shaped block 302. The limiting mechanism 2 includes a mounting block 201 fixed to the bottom surface of the second arc-shaped block 302 and a mounting groove 202 opened on the first arc-shaped block 301. The mounting block 201 and the mounting groove 202 are inserted into each other. A through groove 206 is opened inside the mounting block 201. Two sliding plates 207 are slidably connected in the through groove 206. The two sliding plates 207 are arranged in parallel and opposite to each other. A locking block 205 is fixed on the side of the two sliding plates 207 that is far away from each other. The bottom surface of the locking block 205 is inclined. Specifically, the inclined surface of the locking block 205 faces the opening direction of the mounting groove 202. When the mounting block 201 is inserted into the mounting groove 202, the inclined surface contacts the edge of the mounting groove 202 and pushes the locking block 205 to retract into the through groove 206. A telescopic spring 208 is provided in the through groove 206 between the two slide plates 207. The telescopic spring 208 is always in a compressed state, applying a spring force to the two slide plates 207 to move them away from each other. A slot 203 is provided on the first arc-shaped block 301. The slot 203 is located on the side wall of the mounting groove 202. The locking block 205 is engaged with the slot 203.

[0027] When the second arc-shaped block 302 is engaged, the mounting block 201 is inserted into the mounting groove 202, and the inclined surface of the locking block 205 contacts the edge of the mounting groove 202. The inclined surface is subjected to force, causing the locking block 205 to retract inward against the elastic force of the telescopic spring 208. After the mounting block 201 is fully inserted, the locking block 205 automatically pops out under the action of the telescopic spring 208 and locks into the locking groove 203, locking the first arc-shaped block 301 and the second arc-shaped block 302.

[0028] A push rod 204 is slidably connected to the inner wall of the slot 203. The push rod 204 is a cylindrical push rod, one end of which abuts against one side of the locking block 205. A limiting groove 2031 is formed on the inner wall of the bottom of the slot 203. A limiting block 2041 is fixed to the outer surface of the push rod 204. The limiting block 2041 is slidably connected inside the limiting groove 2031 to guide and limit the movement of the push rod 204, preventing the push rod 204 from coming out of the slot 203. The outer end of the push rod 204 protrudes from the side of the first arc-shaped block 301 for easy pressing by the operator.

[0029] When it is necessary to open the support component 3 to remove or insert the vibration isolation hose, the operator presses the lever 204. The lever 204 overcomes the elastic force of the telescopic spring 208 and pushes the locking block 205 inward, causing the locking block 205 to completely disengage from the slot 203, thus releasing the lock. The second arc-shaped block 302 can then be flipped upward to open the support component 3. When it is necessary to close the support component 3, the second arc-shaped block 302 is flipped downward, and the mounting block 201 is inserted into the mounting slot 202. The inclined surface of the locking block 205 contacts the edge of the mounting slot 202, and the force on the inclined surface causes the locking block 205 to automatically retract. After the mounting block 201 is fully inserted, the locking block 205 automatically pops out under the action of the telescopic spring 208 and locks into the slot 203, completing the locking. This effectively avoids the cumbersome operation of traditional bolt locking methods that require tools, improving the efficiency of vibration isolation hose installation and replacement.

[0030] In use, the following steps are taken: The hanger rods 101 are fixed below the ceiling of the building in the seismic isolation zone. The height of the lower end of the hanger rods 101 is adjusted to keep the support platform 1 horizontal and ensure that each hanger rod 101 is subjected to uniform force. The support platform 1 is then connected and fixed to the lower end of the hanger rods 101 using bolts.

[0031] Next, place the first vibration isolation hose 4 and the second vibration isolation hose 5 on the first arc-shaped block 301 of the corresponding support member 3. Connect both ends of the connecting elbow 6 to one end of the first vibration isolation hose 4 and the second vibration isolation hose 5 respectively through flanges, and snap the connecting elbow 6 into the arc-shaped groove of the trolley 7. Flip and snap the second arc-shaped block 302 of each support member 3, and the limiting mechanism 2 will automatically lock, fixing the vibration isolation hose in the support member 3. Install one end of the return spring 8 on the side plate 701 of the trolley 7, and the other end on the hanger 101, so that the trolley 7 is in a pre-tensioned state. Connect the other end of the first vibration isolation hose 4 to the pipeline in the vibration isolation zone through a flange, and connect the other end of the second vibration isolation hose 5 to the pipeline in the non-vibration isolation zone through a flange, completing the overall installation. This effectively avoids the cumbersome operation of tools required by the traditional bolt locking method and improves the efficiency of vibration isolation hose installation and replacement.

[0032] The trolley 7 is equipped with an elastic buckle made of elastic engineering plastic or spring steel. Its lower end is fixedly connected to the side of the trolley 7, and its upper end has an inwardly extending hook. The opening size of the arc-shaped groove is slightly smaller than the outer diameter of the connecting elbow 6. When installing the connecting elbow 6, press it into the arc-shaped groove from above. The outer wall of the connecting elbow 6 contacts the edge of the opening of the arc-shaped groove and pushes the elastic buckle outward. After the connecting elbow 6 is fully inside the arc-shaped groove, the elastic buckle returns to its original position under its own elastic restoring force, and its hook engages with the upper surface of the connecting elbow 6, locking the connecting elbow 6 in the arc-shaped groove. To disassemble, simply pull the elastic buckle outward to disengage its hook from the upper surface of the connecting elbow 6, allowing the connecting elbow 6 to be removed from the arc-shaped groove. This structure allows for tool-free installation and disassembly of the connecting elbow 6, making operation convenient. Furthermore, it effectively prevents the connecting elbow 6 from falling off the trolley 7 during an earthquake.

[0033] Limiting blocks are fixed at the upper edge of the support platform 1. These blocks are secured to the perimeter of the support platform 1 by welding steel plates or bolting. The height of the limiting blocks is higher than the rolling surface of the balls. When the support member 3 or the trolley 7 slides to the edge of the support platform 1, the limiting blocks abut against the side of the support member 3 or the side of the trolley 7, preventing them from sliding further outwards. This limits the sliding range of the support member 3 and the trolley 7, preventing them from slipping off the support platform 1. The number and position of the limiting blocks are determined according to the shape of the support platform 1 and the sliding direction; typically, one is placed at the end of each sliding direction.

[0034] In summary, the core of the adaptive support structure for the large deformation electromechanical seismic isolation module provided in this embodiment lies in: ball bearings slidably supporting the support member 3 and the trolley 7 on the support platform 1, allowing them to slide freely in any horizontal direction without being restricted by the fixed slide rail direction; the support member 3 effectively prevents the seismic isolation hose from sagging by supporting it from below; the limiting mechanism 2 enables quick locking and unlocking of the support member 3, which can be operated by pressing the lever 204 without tools; the elastic buckle reliably engages the connecting elbow 6 with the trolley 7, preventing it from falling off during an earthquake; the return spring 8 enables automatic reset after an earthquake; and the limiting block prevents the trolley 7 and the support member 3 from slipping off. These structures work together to achieve the comprehensive functions of free deformation, anti-sagging, quick assembly and disassembly, reliable connection, and automatic reset of the seismic isolation hose during an earthquake, making it particularly suitable for supporting long-distance seismic isolation hoses in large deformation seismic isolation modules.
