Description

Technical Field

[0001] This invention relates to the technical field of hoisting supports, and more particularly to a lateral damping device for prefabricated integrated support systems. Background Technology

[0002] The internal electromechanical pipeline systems of industrial buildings are intricate and complex. Traditional support and hanger systems often use on-site welding or simple angle steel hanging, which have insufficient seismic resistance. At present, prefabricated integrated support and hanger technology realizes the integrated layout and modular installation of pipelines through factory prefabrication of channel steel and special connectors.

[0003] However, in existing technologies, hoisting structures often focus on load-bearing and integration, but lack sufficient integration of damping and shock-absorbing components. Some hoisting systems choose springs as shock-absorbing structures, utilizing the spring's own stretchable and deformable physical characteristics to adapt to load changes and complex environmental conditions under different working conditions. The spring absorbs the impact energy generated during hoisting through elastic deformation, while distributing the impact force to various load-bearing components of the hoisting structure. This achieves the initial goals of reducing vibration amplitude, reducing noise propagation, improving equipment operational stability, and extending overall service life. However, the service life of a spring is directly related to the pressure it withstands. During the shock-absorbing process, the spring needs to continuously cope with repeated elastic buffering cycles. When a spring is subjected to such high-frequency and periodic stress for a long period of time, it is prone to elastic fatigue, which leads to a gradual decrease in its damping effect. It cannot effectively offset the impact and vibration during hoisting operations. When the hoisting load exceeds the spring's rated bearing capacity, or when it encounters sudden overload or impact load, the spring not only fails to perform its damping function, but may also suffer serious failures such as breakage and deformation due to excessive pressure. Such failures will directly cause the vibration damping function of the hoisting system to fail, exacerbate the vibration amplitude of the hoisting structure, affect the accuracy and safety of hoisting operations, and cause secondary damage to the hoisting equipment itself and the surrounding working environment, further shortening the overall service life of the hoisting equipment and easily causing safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide a lateral damping device for prefabricated integrated supports and hangers, which solves the problem of fatigue caused by single spring buffers.

[0005] The technical solution of the present invention is as follows: a lateral vibration damping device for prefabricated integrated support and hanger, comprising a support, a support sleeve fixedly connected to the support, a pipeline disposed inside the support sleeve, a long-diameter sliding sleeve fixedly connected to the outside of the pipeline, a collar slidably connected to the outside of the long-diameter sliding sleeve, a buffer component slidably connected inside the support sleeve, a short-diameter pressure sleeve fixedly connected to the outside of the pipeline, a force-bearing ring rotatably connected to the outside of the support sleeve, and a pressure-bearing ring slidably connected to the inside of the support sleeve. The collar is connected to the buffer component, the outside of the buffer component is connected to the force-bearing ring, and the inside of the force-bearing ring is connected to the pressure-bearing ring. The pipeline is buffered by the collar and the buffer component. The pipeline is squeezed by the short-diameter pressure sleeve, causing the force-bearing ring to rotate and push the collar and the buffer component to slide. The collar includes an initial position and a set position. The buffer position is changed when the initial position and the set position of the collar are switched.

[0006] Furthermore, the buffer component includes a sleeve slidably connected inside the support sleeve, multiple buffer springs arranged at equal angles and connected between the sleeve and the collar, two protrusions fixedly connected to both sides of the sleeve, and a convex shaft fixedly connected to the protrusions. Two square bars are arranged inside the sleeve, and the convex shaft is connected to the outside of the force-bearing ring. The two protrusions and the square bars are symmetrically arranged about the central axis of the sleeve.

[0007] Furthermore, the collar is divided into a front ring and a rear ring. The length of the long diameter sliding sleeve is greater than the length from one side of the front ring to one side of the rear ring. Both the front ring and the rear ring are connected to multiple buffer springs. Both the front ring and the rear ring are connected to two pressure blocks. A single square strip is located between the two pressure blocks.

[0008] Furthermore, the pressure ring includes a slide tube slidably connected inside the support sleeve, multiple force-bearing components arranged at equal angles and fixedly connected inside the slide tube, two round shafts arranged and fixedly connected outside the slide tube, and a return spring connected between the support sleeve and the slide tube. The two round shafts are symmetrically arranged about the central axis of the slide tube, and the round shafts are connected to the inside of the pressure ring.

[0009] Furthermore, the outer groove is formed on the outside of the force-bearing ring, and the inner groove is formed on the inside of the force-bearing ring. The convex shaft is located inside the outer groove, and the round shaft is located inside the inner groove.

[0010] Furthermore, the top and bottom of the outer groove are convex ends, and the two sides of the outer groove are concave ends. The convex ends smoothly transition to the concave ends. When the convex shaft is located at the convex end, the collar is in the initial position. When the convex shaft is located at the concave end, the collar is in the set position. The horizontal length from the convex end to the concave end is equal to the length of the long diameter sliding sleeve.

[0011] Furthermore, the inner groove is divided into a bottom section, an upper section, and a smooth section. The left side of the upper section is the short side, the right side of the upper section is the long side, and the connection between the two upper sections is the smooth section. When the return spring is not deformed, the circular shaft is located in the smooth section and is tangent to the bottom section.

[0012] Furthermore, the outer diameter of the short-diameter pressure sleeve is arc-shaped, and a rotating wheel is provided at one end of the force-bearing component near the short-diameter pressure sleeve. When the buffer spring is not deformed, the short-diameter pressure sleeve does not contact the rotating wheel.

[0013] Furthermore, the top of the support sleeve is fixedly connected to a main sleeve frame and a secondary sleeve frame, the bottom of the support sleeve is fixedly connected to a bracket, the sleeve is slidably connected inside the main sleeve frame, the force-bearing ring is rotatably connected outside the secondary sleeve frame, and the sliding tube is slidably connected outside the secondary sleeve frame.

[0014] Furthermore, the bracket is externally fixedly connected with lateral damping rods and longitudinal support rods, which are located on different surfaces of the bracket, and two of each type are provided.

[0015] The beneficial effects of this invention are:

[0016] 1. Through the split front and rear ring structure of the collar, the initial position and the set position can be switched at the same time. Combined with the long stroke sliding adaptation structure of the long diameter sliding sleeve, the working area of ​​the buffer spring is changed, which effectively avoids the problem of local overload damage caused by continuous pressure on a single position of the buffer component. It can realize the partitioned work of the buffer spring when the position is switched, reduce the high frequency of force cycle of a single buffer structure, and reduce its fatigue failure risk.

[0017] 2. By combining multiple sets of equal-angle force-bearing components with a rotating wheel structure, the pressure ring can withstand the compressive force caused by pipeline vibration from all directions. Combined with the automatic reset function of the return spring, it ensures that the pressure ring slides smoothly along the support sleeve without force transmission deviation. The segmented structure design of the inner and outer grooves of the pressure ring accurately converts the linear displacement of the pressure ring into its own rotational motion. Then, through the guiding effect of the outer groove on the convex shaft of the buffer component, it drives the sleeve and the collar to complete synchronous sliding, realizing precise switching of the buffer position. At the same time, the arc-shaped outer diameter design of the short-diameter pressure sleeve can avoid false triggering caused by minor pipeline vibrations. The damping action is only activated under the effective vibration intensity, making the force transmission of the entire damping process more uniform and the action linkage more consistent. It avoids the problem of damping failure caused by action misalignment, and improves the stability and environmental adaptability of the damping process.

[0018] 3. The ring-type split structure forms a front ring and a rear ring, which respectively realize the sliding and rotation limit of the buffer, force ring and pressure ring, providing a stable installation and guiding carrier for the coordinated action of each component. This not only ensures the shock absorption performance of a single damping device, but also ensures a stable fit with the main body of the support and hanger, reducing the risk of pipeline system damage due to vibration and impact, and improving the overall operational safety and seismic protection level of the prefabricated support and hanger.

[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Reference Figures 1-11 This invention provides a lateral damping device for prefabricated integrated supports and hangers, comprising a support 1, a support sleeve 2 fixedly connected to the support 1, a pipe 3 disposed inside the support sleeve 2, a long-diameter sliding sleeve 4 fixedly connected to the outside of the pipe 3, a collar 5 slidably connected to the outside of the long-diameter sliding sleeve 4, a buffer 6 slidably connected inside the support sleeve 2, a short-diameter pressure sleeve 7 fixedly connected to the outside of the pipe 3, a force-bearing ring 8 rotatably connected to the outside of the support sleeve 2, and a pressure-bearing ring 9 slidably connected to the inside of the support sleeve 2. The collar 5 is connected to the buffer 6, the outside of the buffer 6 is connected to the force-bearing ring 8, and the inside of the force-bearing ring 8 is connected to the pressure-bearing ring 9. The pipe 3 is buffered by the collar 5 and the buffer 6, and the pipe 3 is squeezed by the short-diameter pressure sleeve 7, causing the force-bearing ring 8 to rotate and push the collar 5 and the buffer 6 to slide. The collar 5 includes an initial position and a set position, and the buffer position is changed when the initial position and the set position of the collar 5 are switched.

[0034] Specifically, the long-diameter sliding sleeve 4 is fixedly connected to the outside of the pipe 3, forming a sliding fit with the collar 5. The length of the long-diameter sliding sleeve 4 ensures that the collar 5 has sufficient sliding space when switching between the initial position and the set position, meeting the adjustment requirements of different buffer positions. At the same time, the smooth surface of the long-diameter sliding sleeve 4 reduces component wear, ensuring smooth movement of the collar 5 during vibration transmission and avoiding excessive sliding resistance, thus preventing lag in the damping response. The collar 5 is slidably connected to the long-diameter sliding sleeve 4 on one hand and to the buffer 6 on the other. When the pipe 3 vibrates, the vibration energy on the pipe 3 is compressed by the long-diameter sliding sleeve 4 and the collar 5 to buffer the vibration of the buffer 6, allowing the vibration energy on the pipe 3 to be quickly transmitted to the buffer 6 through the collar 5. The collar 5 is designed to... It has two states: initial position and set position. Switching between them can change the buffer position, thus changing the position of the compressed component 6. This prevents continuous pressure on a single position and avoids damage to the component due to excessive local force. The pressure ring 9 is slidably connected inside the support sleeve 2. Under the compression of the short-diameter pressure sleeve 7, it can slide along the guide trajectory of the support sleeve 2. The pressure ring 9 also moves accordingly to compress the inside of the force ring 8. The force ring 8 converts the linear compression force into its own rotational force. Thus, the pressure ring 9, guided by the support sleeve 2, avoids force transmission deviation, ensuring stable triggering of subsequent force conversion and vibration reduction. This effectively solves the problems of fatigue and overload failure, improves vibration reduction stability and environmental adaptability, and ensures the safety of equipment operation.

[0035] Reference Figures 2-5 The buffer component 6 includes a sleeve 61 slidably connected inside the support sleeve 2, multiple buffer springs 62 arranged at equal angles and connected between the sleeve 61 and the collar 5, two protrusions 63 fixedly connected to both sides of the sleeve 61, and a convex shaft 64 fixedly connected to the protrusions 63. Two square bars 611 are arranged inside the sleeve 61, and the convex shaft 64 is connected to the outside of the force ring 8. The two protrusions 63 and the square bars 611 are symmetrically arranged about the central axis of the sleeve 61. The sleeve 61 provides a stable mounting carrier for the buffer springs 62 and the protrusions 63. Its sliding cooperation with the support sleeve 2 ensures the smoothness of the buffer stroke. The buffer springs 62, which are distributed at equal angles, can evenly bear the vibration energy transmitted by the collar 5, improving the stability and uniformity of the shock absorption. The protrusions 63 and the convex shaft 64 ensure that the rotational force of the force ring 8 can be efficiently transmitted to the sleeve 61.

[0036] Reference Figures 3-6 The collar 5 is divided into a front ring 51 and a rear ring 52. The length of the long diameter sliding sleeve 4 is greater than the length from one side of the front ring 51 to the other side of the rear ring 52. Both the front ring 51 and the rear ring 52 are connected to multiple buffer springs 62. Both the front ring 51 and the rear ring 52 are connected to two pressure blocks 53. A single square bar 611 is located between the two pressure blocks 53. When the sleeve 61 moves, it will push the pressure blocks 53 that are attached on both sides through the square bar 611, so that the front ring 51 and the rear ring 52 move synchronously.

[0037] Specifically, when the front ring 51 and the rear ring 52 move, if the collar 5 is in the initial position, the rear ring 52 is outside the range of the long diameter sliding sleeve 4. At this time, the long diameter sliding sleeve 4 will not compress the buffer spring 62 connected to the rear ring 52, so that the buffer spring 62 in this area is in a temporary non-working state. When the front ring 51 is outside the range of the long diameter sliding sleeve 4, the long diameter sliding sleeve 4 will not compress the buffer spring 62 connected to the front ring 51, so that the buffer spring 62 in this area is in a temporary non-working state. This reduces the high frequency of stress caused by repeated elastic buffering cycles, thereby reducing the risk of fatigue failure.

[0038] When the sleeve 61 moves, it pushes the pressure blocks 53 on both sides through the square bar 611. This rigid transmission structure ensures that the front ring 51 and the rear ring 52 move synchronously, avoiding misalignment in the split structure and ensuring the consistency of the linkage. The front ring 51 and the rear ring 52 form a sliding fit with the long diameter sliding sleeve 4. On the other hand, the buffer spring 62 is connected to the buffer component 6, so that the vibration energy on the pipeline 3 can be quickly and evenly transmitted to the buffer component 6 through the sleeve 5. More importantly, the sleeve 5 is set with two states: initial position and set position. By switching between the two, the buffer position can be changed, and the working state of the buffer spring 62 can be switched. This avoids the limitation of a single buffer stroke, reduces the risk of fatigue failure, and can effectively reduce the number of high-frequency force-bearing components caused by repeated elastic buffer cycles under different working conditions. It also reduces the continuous load on a single spring, thereby improving the fatigue resistance of the buffer spring 62 and extending its service life.

[0039] Reference Figures 3-8 The pressure ring 9 includes a slide tube 91 slidably connected inside the support sleeve 2, multiple force-bearing components 92 arranged at equal angles and fixedly connected inside the slide tube 91, two round shafts 93 arranged and fixedly connected outside the slide tube 91, and a return spring 94 connected between the support sleeve 2 and the slide tube 91. The two round shafts 93 are symmetrically arranged about the central axis of the slide tube 91, so that the local extrusion pressure of the short-diameter pressure sleeve 7 can be evenly applied to the pressure ring 8, ensuring stability. The round shafts 93 are internally connected to the pressure ring 8.

[0040] The outer diameter of the short-diameter pressure sleeve 7 is arc-shaped. A rotating wheel 921 is provided at one end of the force-bearing component 92 near the short-diameter pressure sleeve 7. When the buffer spring 62 is not deformed, the short-diameter pressure sleeve 7 does not contact the rotating wheel 921, so as to avoid the pressure ring 9 moving as a whole when the pipeline 3 generates a slight vibration.

[0041] Specifically, multiple rotating wheels 921 are used to ensure that the short-diameter pressure sleeve 7 can compress the rotating wheel 921 from any direction. When the rotating wheel 921 is compressed, the force-bearing component 92 and the slide tube 91 move synchronously. The slide tube 91 will stretch the return spring 94 to store force, and at the same time drive the round shaft 93 to move. The round shaft 93 is used to compress the force ring 8, causing the force ring 8 to rotate.

[0042] Among them, the force-bearing components 92, distributed at equal angles, combined with the rotating wheel 921, form a multi-directional extrusion bearing structure. This ensures that the extrusion force generated by the short-diameter pressure sleeve 7 from any direction can act on the rotating wheel 921, ensuring that the linear displacement force of the slide tube 91 is evenly transmitted to the inside of the force-bearing ring 8. The return spring 94, as a reset actuator, provides the elastic driving force for the automatic return of the pressure ring 9 as a whole, ensuring that it can quickly return to its initial state after the extrusion action, preparing for the next shock absorption trigger. From the perspective of the action coordination process, when the pipeline 3 vibrates, it will drive the short-diameter pressure sleeve 92 to rotate. When sleeve 7 is displaced, and the vibration intensity changes to different magnitudes, when the vibration intensity causes the arc-shaped outer diameter of the short-diameter pressure sleeve 7 to contact the rotating wheel 921 and generate compression, the compression force can be smoothly transmitted to the force-bearing component 92 by means of the rolling characteristics of the rotating wheel 921, causing the force-bearing component 92 and the slide tube 91 to slide synchronously along the radial direction of the support sleeve 2. During the sliding process, the slide tube 91 will stretch the return spring 94, so that the return spring 94 completes the storage of force. At the same time, the slide tube 91 drives the symmetrical circular shafts 93 on both sides to move synchronously. The circular shafts 93 generate balanced compression on the inside of the force ring 8, thereby triggering the smooth rotation of the force ring 8.

[0043] Reference Figures 2-8 The outer groove 81 is provided on the outside of the force ring 8, and the inner groove 82 is provided inside the force ring 8. The convex shaft 64 is located inside the outer groove 81, and the round shaft 93 is located inside the inner groove 82. When the round shaft 93 moves, it squeezes the inner groove 82, causing the force ring 8 to rotate under force. When the force ring 8 rotates, the outer groove 81 guides the convex shaft 64.

[0044] The top and bottom of the outer groove 81 are convex ends 811, and the two sides of the outer groove 81 are concave ends 812. The convex ends 811 smoothly transition to the concave ends 812, reducing the frictional resistance when the convex shaft 64 moves in the groove. When the convex shaft 64 is located at the convex end 811, the collar 5 is in the initial position. When the convex shaft 64 is located at the concave end 812, the collar 5 is in the set position. The horizontal length from the convex end 811 to the concave end 812 is equal to the length of the long diameter sliding sleeve 4, ensuring that when the force ring 8 rotates 90 degrees, the collar 5 moves by the length of one long diameter sliding sleeve 4. That is, if the collar 5 is in the initial position at this time, then the collar 5 will move from the initial position to the set position.

[0045] Specifically, during the rotation of the force ring 8, the outer groove 81 guides the convex shaft 64 to move through the structure of the convex end 811 and the concave end 812, thereby driving the sleeve 61 to slide and pushing the collar 5 to move along the long diameter sliding sleeve 4 to achieve position switching. This ensures the accuracy of the collar 5 position switching, further strengthens the coordination and consistency of the entire damping system, and avoids damping failure caused by component misalignment.

[0046] Reference Figures 3-9The inner groove 82 is divided into a bottom section 821, an upper section 822, and a smooth section 823. The left side of the upper section 822 is the short side, and the right side of the upper section 822 is the long side, so that the vertices of the bottom section 821 and the upper section 822 are staggered, ensuring that the right side of the upper section 822 is squeezed when the circular shaft 93 moves back. The connection point of the two upper sections 822 is the smooth section 823. When the return spring 94 is not deformed, the circular shaft 93 is located at the smooth section 823, so that the circular shaft 93 will not contact the smooth section 823, avoiding interference to the circular shaft 93. The circular shaft 93 is tangent to the bottom section 821. The bottom section 821, the upper section 822, and the smooth section 823 form a unit. The inner groove 82 is composed of multiple units set at equal angles connected together.

[0047] Specifically, when the circular shaft 93 moves, it first compresses the bottom section 821, causing the force-bearing ring 8 to rotate. When the circular shaft 93 compresses the bottom section 821, if the front ring 51 or the rear ring 52 has already contacted the side of the long diameter sliding sleeve 4, and the side of the long diameter sliding sleeve 4 is provided with a chamfer, the moving front ring 51 or the rear ring 52 will be compressed and enter the range of the long diameter sliding sleeve 4. In addition, when the pipeline 3 and the long diameter sliding sleeve 4 move back, the short diameter pressure sleeve 7 will also move back synchronously, and the circular shaft 93 will also move back accordingly. The returning circular shaft 93 will squeeze the right side of the upper section 822, causing the force ring 8 to rotate again. If the front ring 51 or the rear ring 52 is about to enter the range of the long diameter sliding sleeve 4, the pipe 3 and the long diameter sliding sleeve 4 will first move back, and then the force ring 8 will rotate. As a result, the front ring 51 or the rear ring 52 will enter the range of the long diameter sliding sleeve 4, dividing the single rotation of the force ring 8 into two segments, thereby avoiding excessive interference between the front ring 51 or the rear ring 52 and the long diameter sliding sleeve 4, and effectively making the force ring 8 rotate stably.

[0048] The inner groove 82 adopts a segmented unit structure design. The groove is divided into a bottom section 821, an upper section 822, and a smooth section 823. The left side of the upper section 822 is the short side and the right side is the long side, so that the vertices of the bottom section 821 and the upper section 822 form an interlaced layout. This layout can ensure that the circular shaft 93 can accurately squeeze the right side of the upper section 822 when it moves back. The connection between the two upper sections 822 is the smooth section 823. When the return spring 94 is not deformed, the circular shaft 93 is located at the smooth section 823 and does not contact the smooth section 823, effectively avoiding interference to the circular shaft 93. At the same time, the circular shaft 93 is tangent to the bottom section 821, ensuring the positioning stability in the initial state.

[0049] Reference Figures 1-11 The top of the support sleeve 2 is fixedly connected to the main sleeve 21 and the auxiliary sleeve 22. The bottom of the support sleeve 2 is fixedly connected to the bracket 1. The sleeve 61 is slidably connected inside the main sleeve 21. The force ring 8 is rotatably connected outside the auxiliary sleeve 22. The sliding tube 91 is slidably connected outside the auxiliary sleeve 22.

[0050] The external fixed connection of the support 1 includes a lateral damping rod 101 and a longitudinal support rod 102. The lateral damping rod 101 and the longitudinal support rod 102 are located on different surfaces of the support 1. There are two lateral damping rods 101 and two longitudinal support rods 102, which are connected by hinges to avoid brittle failure. At the same time, the lateral damping rod 101, the longitudinal support rod 102 and the pipeline 3 are provided with anti-seismic damping rubber pads to form a multiple shock absorption mechanism, reduce the risk of pipeline system damage and improve lateral seismic performance.

[0051] The working principle of this invention is as follows: When the pipeline 3 generates lateral vibration, the vibration energy is transmitted to the collar 5 via the long-diameter sliding sleeve 4, and then to the buffer 6 via the collar 5. The buffer spring 62 receives the vibration extrusion force and undergoes elastic deformation, converting the vibration kinetic energy of the pipeline 3 into elastic potential energy, thus achieving initial vibration attenuation. When the lateral vibration intensity of the pipeline 3 reaches the set threshold, the short-diameter pressure sleeve 7 outside the pipeline 3 displaces and comes into contact with the rotating wheel 921 of the pressure ring 9, which compresses it. The extrusion force is transmitted to the sliding tube 91 via the force-bearing component 92, causing the sliding tube 91 to slide radially along the secondary sleeve 22 of the support sleeve 2. When the sliding tube 91 slides, the stretch return spring 94 stores force, and at the same time, it drives the round shaft 93 to move. The round shaft 93 compresses the bottom section 821 of the inner groove 82 of the force ring 8, converting the linear displacement force of the sliding tube 91 into the rotational driving force of the force ring 8, causing the force ring 8 to rotate smoothly around the secondary sleeve 22. When the force ring 8 rotates, it passes through the outer groove 8 A guide shaft 64 is formed to push the convex shaft 64 to move within the outer groove 81, thereby driving the sleeve 61 to slide along the main sleeve frame 21. The sleeve 61 pushes the front ring 51 and the rear ring 52 to slide synchronously along the long diameter sliding sleeve 4 through the internal square bar 611, causing the collar 5 to move and gradually switch positions. When the position of the collar 5 is switched, the buffer area alternates accordingly. In the initial position, only the buffer spring 62 on the front ring 51 side bears the vibration load. In the set position, only the buffer spring 62 on the rear ring 52 side works. This alternation avoids the buffer spring 62 from being subjected to continuous high-frequency force, reducing the risk of fatigue failure of the buffer component 6. When the pipeline 3 and the long diameter sliding sleeve 4 move back, the short diameter pressure sleeve 7 resets synchronously. The return spring 94 releases its stored force to drive the slide tube 91 and the round shaft 93 to move back in the opposite direction. The moving round shaft 93 presses the right side of the upper section 822 of the inner groove 82, so that the force ring 8 completes a second smooth rotation. The entire device is reset and ready for the next shock absorption trigger.
