Description

Technical Field

[0001] This invention relates to the field of seismic bracing technology, specifically to a seismic bracing support structure. Background Technology

[0002] Seismic bracing structures are seismic-resistant load-bearing components used in building electromechanical engineering for pipeline systems. Their main function is to constrain the displacement of pipelines under seismic action and transfer the gravity load and seismic force of the pipelines to the main building structure. When an earthquake occurs, seismic waves will generate vertical and horizontal vibration loads. If the pipeline system lacks effective seismic support, it will cause the pipeline to sway, the joints to break or even fall off, which may lead to serious secondary disasters such as fires and gas leaks. To avoid the above situations, a seismic bracing structure is needed.

[0003] Existing seismic bracing systems are mainly divided into two categories: rigid seismic bracing systems and flexible seismic bracing systems. Rigid seismic bracing systems directly transfer the energy generated by pipe swaying to the main building structure through rigid components such as lateral channel steel; flexible seismic bracing systems, on the other hand, dissipate the energy of pipe swaying during an earthquake through elastic elements such as springs and dampers.

[0004] The inventors of this application discovered in their research that the core defect of the aforementioned prior art is that the functions of rigid and flexible seismic bracing in the prior art are independent of each other. The same bracing cannot flexibly switch between rigid support and buffering and damping modes according to the actual working conditions. Rigid seismic bracing can meet the displacement constraint requirements under high-intensity earthquakes, but under small-amplitude vibration conditions such as daily wind vibration and equipment operation vibration, due to the lack of buffering, the vibration impact is directly and rigidly transmitted to the pipeline, which can easily cause stress concentration and fatigue damage at the pipeline interface. Flexible seismic bracing can dissipate impact energy, but when a high-intensity earthquake occurs, due to the existence of elastic buffer displacement, it cannot form a strict displacement constraint on the pipeline, making it difficult to meet the strict restriction requirements on pipeline displacement under high-intensity earthquakes. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a seismic bracing support structure that solves the problem that rigid and flexible seismic bracing in existing technologies have independent functions, and the same bracing cannot flexibly switch between rigid support and buffering and damping modes according to actual working conditions.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a seismic bracing support structure, comprising a support frame, a rotating shaft rotatably connected inside the support frame, a circular gear fixedly connected to the outer wall of the rotating shaft, racks symmetrically meshing with the tooth ends of the circular gear along the central axis, a sliding rod fixedly connected to one end of each of the two racks, the outer walls of the two sliding rods slidably connected to both sides of the support frame, a connecting plate fixedly connected to one side of each of the two sliding rods, a snap-fit ​​block fixedly connected to one end of the connecting plate, an mounting plate slidably connected to the top of the support frame, and slots matching the snap-fit ​​blocks being formed inside both sides of the mounting plate; A fixing component is installed on the top of the mounting plate, the fixing component including mounting seats that are uniformly and fixedly connected to the top of the mounting plate symmetrically arranged.

[0007] By adopting the above technical solution, the rotating shaft drives the circular gear to rotate, and through gear meshing transmission, it drives two racks arranged symmetrically on the central axis to move synchronously in opposite directions. The slide bar moves along the support frame towards the inside of the support frame with the rack, and the locking block moves synchronously with the slide bar towards the locking groove on the side wall of the mounting plate until the locking block is completely embedded in the locking groove, forming a concave-convex locking limit. At this time, the vertical displacement of the mounting plate is constrained by the locking block, realizing the rigid seismic support function and meeting the displacement constraint requirements under high-intensity earthquakes. When it is necessary to switch to the buffer and shock absorption mode, the rotating shaft and the circular gear are rotated in the opposite direction. Through the gear meshing transmission, the two racks are driven to move outward. The racks push the slide rod to extend along the support frame. Through the connecting plate, the locking block is completely disengaged from the slot, so that the support frame can absorb the impact under normal vibration conditions.

[0010] Preferably, a worm gear is fixedly connected to the other end of the connecting shaft, a worm is meshed with the tooth end of the worm gear, a support shaft is fixedly connected to the inner wall of the worm, the outer wall of the support shaft is rotatably connected to the mounting frame, and a rotating handle is fixedly connected to one end of the support shaft.

[0011] Preferably, the outer wall of the rotating handle is provided with positioning holes evenly, a side plate is fixedly connected to one side of the mounting frame, a locking screw is threaded into the inside of the side plate, and one end of the locking screw is threaded into one of the positioning holes.

[0012] Preferably, the support frame has connecting cylinders uniformly fixedly connected inside, and movable rods are slidably connected to both sides of the multiple connecting cylinders. A sealing plate is fixedly connected to one end of the movable rod, and the outer wall of the sealing plate is slidably connected to the inner wall of the connecting cylinder. A connecting seat is fixedly connected to the other end of the sealing plate, and a connecting rod is hinged inside the connecting seat. A support seat is hinged to one end of the connecting rod, and the top of the support seat is fixedly connected to the bottom of the mounting plate.

[0013] Preferably, a spring is fixedly connected to one side of the sealing plate, one end of the spring is fixedly connected to one side of the connecting cylinder, the inner wall of the spring is sleeved on the outer wall of the movable rod, and dampers are symmetrically arranged on the opposite side of the sealing plate and the movable rod.

[0014] Preferably, a straight pipe and an exhaust pipe are symmetrically fixedly connected to the outer wall of the connecting cylinder. One-way valve one and one-way valve two are respectively installed on the outer walls of the straight pipe and the exhaust pipe. The outer wall of the straight pipe extends through to the outer wall of the support frame.

[0015] Preferably, both sides of the support frame are symmetrically fixedly connected with fixing blocks, the top of the fixing blocks are fixedly connected with a first hanging rod, one end of each fixing block is provided with a groove, a second hanging rod is hinged in the groove of the fixing block, and the top of the first hanging rod and the second hanging rod are fixedly connected with an assembly block.

[0016] This invention provides a seismic bracing structure. It has the following beneficial effects: 1. In this invention, when the support frame and the mounting plate need to form a rigid force transmission and seismic resistance, rotating the rotating shaft drives the circular gear to rotate. Through gear meshing, the two symmetrical racks are driven to move inward synchronously. The sliding rod moves with the racks into the support frame, causing the locking block to embed into the locking groove on the side wall of the mounting plate, forming a concave-convex locking limit, constraining the relative displacement of the mounting plate, so that the two form an integral rigid structure. The load can be directly transferred to the hoisting structure to achieve rigid seismic support. When it is necessary to switch to the buffer and shock absorption mode, the rotating shaft and the gear are rotated in the opposite direction, driving the rack to move outward. The sliding rod extends and drives the locking block to disengage from the locking groove, releasing the limitation on the mounting plate. The mounting plate can generate vertical relative displacement, thereby absorbing the impact energy under daily vibration conditions.

[0017] 2. In this invention, rotating the rotating handle drives the support shaft and worm to rotate. Through the meshing transmission of the worm wheel and worm, the worm drives the worm wheel to generate deceleration and torsional motion. The worm wheel coaxially drives the connecting shaft to rotate synchronously inside the mounting frame. When the connecting shaft rotates, it gradually winds and wraps multiple straps around the bottom of the guide rod around its own outer wall. The other end of the straps is wrapped around the mounting base and gradually tightened, gradually hugging the outer wall of the pipe from above until the straps form sufficient clamping force on the outer wall of the pipe, realizing a rigid connection between the pipe and the mounting plate. At the same time, it can fix pipes of different sizes at multiple points simultaneously.

[0018] 3. In this invention, when the mounting plate is subjected to vertical impact vibration, it drives the support seat to generate a synchronous vertical displacement. The support seat converts the vertical impact load into a horizontal thrust through a hinged connecting rod, pushing the movable rod and the sealing plate to slide back and forth along the inner wall of the connecting cylinder. The spring is compressed or stretched synchronously with the sealing plate, absorbing the instantaneous impact energy through elastic deformation. At the same time, the damper generates damping resistance synchronously, continuously consuming vibration energy and suppressing the spring's reciprocating rebound. During the sliding process of the sealing plate, the volume of the closed chamber between it and the end of the connecting cylinder changes. When the volume decreases, the air in the chamber is compressed, the exhaust one-way valve opens, and the intake one-way valve closes, and the air is discharged through the exhaust pipe. When the volume increases, the chamber forms a negative pressure, the intake one-way valve opens, and the exhaust one-way valve closes, and outside air is drawn into the chamber through the straight pipe. With the help of the elastic auxiliary buffer of the closed air, rigid impact between the sealing plate and the end of the connecting cylinder is avoided. Attached Figure Description

[0021] The technical solution of the present invention will now be clearly and completely described 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.

[0022] Please see the appendix Figure 1 -Appendix Figure 3 Appendix Figure 5 -Appendix Figure 7 This invention provides a seismic bracing support structure, including a support frame 1. A rotating shaft 2 is rotatably connected inside the support frame 1. A circular gear 201 is fixedly connected to the outer wall of the rotating shaft 2. The tooth ends of the circular gear 201 are symmetrically meshed with racks 202 along the central axis. A slide rod 203 is fixedly connected to one end of each rack 202. The outer walls of the two slide rods 203 are slidably connected to both sides of the support frame 1. A connecting plate 204 is fixedly connected to one side of each slide rod 203. A snap-fit ​​block 205 is fixedly connected to one end of the connecting plate 204. An mounting plate 206 is slidably connected to the top of the support frame 1. A slot 207 matching the snap-fit ​​block 205 is opened inside both sides of the mounting plate 206. A fixing component is installed on the top of the mounting plate 206. The fixing component includes mounting seats 3 that are symmetrically arranged on the top of the mounting plate 206 and are evenly and fixedly connected to it.

[0023] Specifically, when the support frame 1 and the mounting plate 206 need to form a rigid connection to achieve rigid force transmission and seismic resistance, the operator drives the circular gear 201 to rotate through the rotating shaft 2. Through gear meshing, the two racks 202, which are symmetrically arranged on the central axis, are driven to move inward synchronously in opposite directions. The sliding rod 203 moves along the support frame 1 towards the interior of the support frame 1 with the rack 202. The locking block 205 moves synchronously with the sliding rod 203 towards the slot 207 on the side wall of the mounting plate 206 until the locking block 205 is completely embedded in the slot 207, forming a concave-convex locking limit. At this time, the vertical displacement of the mounting plate 206 is constrained by the locking block 205 and cannot move relative to the support frame 1. The support frame 1 and the mounting plate 206 form an integral rigid structure. The gravity load of the pipeline and the horizontal and vertical loads of the earthquake can be directly transmitted to the top hoisting structure through the rigid connection path without relative buffer displacement, realizing the rigid seismic support function and meeting the displacement constraint requirements under high-intensity earthquakes. When it is necessary to switch to the buffer and shock absorption mode to dissipate seismic impact energy, the rotating shaft 2 and the circular gear 201 are rotated in the opposite direction. Through gear meshing, the two racks 202 are driven to move outward. The racks 202 push the slide rod 203 to extend along the support frame 1. Through the connecting plate 204, the locking block 205 is completely disengaged from the slot 207, releasing the locking limit on the mounting plate 206. At this time, the mounting plate 206 can be vertically displaced relative to the support frame 1, absorbing impact energy under normal vibration conditions. The fixing component is used for the rigid connection between the pipe and the mounting plate 206, and can simultaneously fix pipes of different sizes at multiple points.

[0024] Please see the appendix Figure 3 -Appendix Figure 4 The bottom of the rotating shaft 2 is fixedly connected to the outer wall of the support frame 1 with a handle 208. The handle 208 is internally threaded with a limit rod 210. Limit holes 209 are evenly opened at the bottom of the support frame 1. One end of the limit rod 210 is threaded into one of the limit holes 209.

[0025] Specifically, after the rigid connection and buffer damping mode switching are completed, the limiting rod 210 connected by the internal thread of the handle 208 is rotated, so that the limiting rod 210 is screwed forward along the thread until its end is screwed into the corresponding limiting hole 209, forming a threaded mechanical lock. Through the cooperation of the limiting rod 210 and the limiting hole 209, the accidental rotation of the handle 208 and the rotating shaft 2 is restricted, avoiding the accidental disengagement or locking of the locking block 205 due to earthquake reciprocating vibration or daily equipment vibration. When switching operations are required, the end of the limiting rod 210 is screwed out from the corresponding limiting hole 209, and then the rotating shaft 2 is rotated by the handle 208.

[0026] Please see the appendix Figure 1 Appendix Figure 5 -Appendix Figure 7 Two mounting bases 3 are rotatably connected to opposite sides of a strap 301. Mounting blocks 302 are symmetrically fixedly connected to the top of mounting plate 206. Guide rods 303 are fixedly connected to opposite sides of two mounting blocks 302. Connecting blocks 304 and mounting frames 305 are fixedly connected to the top two ends of mounting plate 206 respectively. Connecting shaft 306 is rotatably connected inside mounting frame 305. One end of connecting shaft 306 is rotatably connected inside mounting frame 305. One end of strap 301 passes through the bottom of guide rod 303 and wraps around the outer wall of connecting shaft 306. One end of strap 301 is fixedly connected to the outer wall of connecting shaft 306. The other end of the connecting shaft 306 is fixedly connected to a worm gear 4, the tooth end of the worm gear 4 is meshed with a worm 401, the inner wall of the worm 401 is fixedly connected to a support shaft 402, the outer wall of the support shaft 402 is rotatably connected to the mounting frame 305, and one end of the support shaft 402 is fixedly connected to a rotating handle 403. The outer wall of the rotating handle 403 is evenly provided with positioning holes 406. A side plate 404 is fixedly connected to one side of the mounting frame 305. A locking screw 405 is threaded inside the side plate 404. One end of the locking screw 405 is threaded into one of the positioning holes 406.

[0027] Specifically, when fixing the pipe, firstly, the end of the locking screw 405 is completely disengaged from the positioning hole 406 to release the rotation constraint on the rotating handle 403. Then, the rotating handle 403 is rotated, which drives the support shaft 402 and the worm 401 to rotate. Through the meshing transmission of the worm wheel 4 and the worm 401, the worm 401 drives the worm wheel 4 to generate deceleration and torsional motion. The worm wheel 4 coaxially drives the connecting shaft 306 to rotate synchronously inside the mounting frame 305. When the connecting shaft 306 rotates, it gradually winds and wraps the multiple straps 301 that pass around the bottom of the guide rod 303 around its own outer wall. The other end of the straps 301 is wrapped around the mounting base 3 and gradually tensioned, gradually hugging the outer wall of the pipe from above until the straps 301 form sufficient clamping force on the outer wall of the pipe, realizing the rigid connection between the pipe and the mounting plate 206. At the same time, it can fix pipes of different sizes at multiple points simultaneously. After the strap 301 is tightened to the set clamping force, the locking screw 405 is rotated in the opposite direction so that its end is screwed into the corresponding positioning hole 406 to form a threaded lock. Utilizing the reverse self-locking characteristics of the worm gear 4 and worm 401 transmission, combined with the mechanical locking of the locking screw 405, a double anti-loosening effect is achieved, preventing the strap 301 from loosening and the pipe from shifting laterally under the reciprocating vibration of an earthquake, and ensuring the reliability of the connection between the pipe and the mounting plate 206. The guide rod 303 plays a guiding and supporting role for the strap 301, ensuring the clamping effect of the strap 301 on the pipe.

[0028] Please see the appendix Figure 2 Appendix Figure 5 Appendix Figure 7 The support frame 1 has connecting cylinders 5 evenly fixedly connected inside. Multiple connecting cylinders 5 are slidably connected to both sides of movable rods 501. One end of the movable rod 501 is fixedly connected to a sealing plate 502. The outer wall of the sealing plate 502 is slidably connected to the inner wall of the connecting cylinder 5. The other end of the sealing plate 502 is fixedly connected to a connecting seat 503. The connecting seat 503 is hinged to a connecting rod 504 inside. One end of the connecting rod 504 is hinged to a support seat 505. The top of the support seat 505 is fixedly connected to the bottom of the mounting plate 206. A spring 506 is fixedly connected to one side of the sealing plate 502. One end of the spring 506 is fixedly connected to one side of the connecting cylinder 5. The inner wall of the spring 506 is sleeved on the outer wall of the movable rod 501. Dampers are symmetrically arranged on the opposite side of the sealing plate 502 and the movable rod 501. A straight pipe 507 and an exhaust pipe 509 are symmetrically fixedly connected to the outer wall of the connecting cylinder 5. One-way valve 508 and one-way valve 510 are respectively installed on the outer walls of the straight pipe 507 and the exhaust pipe 509. The outer wall of the straight pipe 507 extends through to the outer wall of the support frame 1.

[0029] Specifically, when the mounting plate 206 is subjected to vertical impact vibration, it drives the support base 505 to generate vertical displacement synchronously. The support base 505 drives the connecting rod 504 to swing through the hinge, converting the vertical impact load into a horizontal thrust. The connecting base 503 pushes the movable rod 501 to slide back and forth along the axial direction of the connecting cylinder 5. When the movable rod 501 drives the sealing plate 502 to slide on the inner wall of the connecting cylinder 5, the spring 506 is simultaneously compressed or stretched. The elastic deformation of the spring 506 absorbs the instantaneous impact energy, converting the impact load into a gentle elastic force, reducing the impact acceleration of the pipeline. At the same time, the dampers symmetrically arranged on the side of the sealing plate 502 generate damping resistance synchronously, continuously consuming vibration energy, suppressing the reciprocating rebound of the spring 506, avoiding continuous oscillation of the pipeline, and achieving rapid vibration reduction. As the sealing plate 502 slides inside the connecting cylinder 5, it changes the volume of the enclosed chamber between the sealing plate 502 and the end of the connecting cylinder 5, thereby enhancing the buffering effect through gas elasticity and the throttling damping formed with the exhaust gas. When the sealing plate 502 slides towards the middle of the connecting cylinder 5 and the volume of the closed chamber decreases, the air in the chamber is compressed, the air pressure increases, and a gas elastic reaction force is formed to resist the sliding, which helps to absorb the impact energy. At the same time, the pressure in the chamber causes the second check valve 510 to open and the first check valve 508 to close, and the air is discharged to the outside through the exhaust pipe 509. When the sealing plate 502 retracts towards the middle of the connecting cylinder 5 and moves towards both ends of the connecting cylinder 5, the volume of the closed chamber increases and a negative pressure is formed in the chamber. At this time, the first check valve 508 opens and the second check valve 510 closes. Outside air is drawn into the chamber through the straight pipe 507 and the first check valve 508. The air elasticity of the closed chamber formed in the connecting cylinder 5 further enhances the buffering effect, while avoiding rigid impact between the sealing plate 502 and the end of the connecting cylinder 5, reducing impact noise and rigid stress of the components, and extending the service life of the structure.

[0030] Please see the appendix Figure 1 -Appendix Figure 3 Both sides of the support frame 1 are symmetrically fixedly connected with fixing blocks 6. The top of the fixing block 6 is fixedly connected with a first hanger 601. One end of the fixing block 6 is provided with a groove 602. The second hanger 603 is hinged in the groove 602 of the fixing block 6. The top of the first hanger 601 and the second hanger 603 are fixedly connected with an assembly block 604.

[0031] Specifically, the main vertical gravity load of the pipeline and the support frame 1 is borne by the first hanger 601, ensuring the stability of the pipeline's daily load-bearing capacity. The second hanger 603, which is hinged and arranged at an incline, forms a triangular stable force system with the first hanger 601, which can effectively transfer the horizontal seismic load, constrain the horizontal displacement of the support frame 1, and achieve lateral seismic protection. The assembly blocks 604 at the top of both hanger 1 601 and hanger 2 603 are fixedly connected to the main building structure through anchor bolts, so as to reliably transfer the overall gravity load and seismic force of the support to the main building structure.

[0032] Work process: When switching to rigid force transmission mode, the handle 208 drives the rotating shaft 2 and the circular gear 201 to rotate. The gear meshing drives the two symmetrical racks 202 to move inward synchronously. The slide rod 203 moves inward along the support frame 1 with the racks 202, which drives the snap block 205 to be embedded in the snap groove 207 on the side wall of the mounting plate 206, constraining the relative displacement of the mounting plate 206, so that the support frame 1 and the mounting plate 206 form a rigid whole. Rotate the rotating shaft 2 in the opposite direction, the rack 202 moves outward, the locking block 205 disengages from the slot 207, and switches to the buffer and shock absorption mode. After switching, rotate the limiting rod 210 in the handle 208 so that its end is screwed into the corresponding limiting hole 209, locking the rotation state of the rotating shaft 2. Unscrew the locking screw 405 to release the rotation constraint of the rotating handle 403. Rotate the rotating handle 403 to drive the support shaft 402 and the worm gear 401 to rotate synchronously. Through the meshing transmission of the worm wheel 4, the connecting shaft 306 is driven to rotate in the mounting frame 305. The binding strap 301 that passes around the bottom of the guide rod 303 is wound up to the outer wall of the connecting shaft 306. The binding strap 301 is gradually tightened and hugs the outer wall of the pipe. After tightening, screw the locking screw 405 into the corresponding positioning hole 406 to lock the rotating handle 403. In buffer mode, the mounting plate 206 is subjected to vertical vibration, which drives the support base 505 to move synchronously. The vertical load is converted into horizontal thrust through the connecting rod 504 and the connecting base 503, which drives the movable rod 501 to drive the sealing plate 502 to slide back and forth along the inner wall of the connecting cylinder 5. The spring 506 is compressed or stretched synchronously with the sealing plate 502, and the damper generates damping resistance synchronously. The movement of the sealing plate 502 changes the volume of the end chamber of the connecting cylinder 5. When the volume decreases, the second check valve 510 opens, and air is discharged through the exhaust pipe 509. When the volume increases, the first check valve 508 opens, and outside air is drawn into the chamber through the straight pipe 507. The first hanger 601 bears the vertical gravity load, and the second hanger 603 is hinged in the groove 602 of the fixed block 6, forming a triangular force system with the first hanger 601 to transfer the horizontal load. The assembly block 604 at the top of the first hanger 601 and the second hanger 603 is anchored to the main structure of the building to transfer the entire load.
