Description

Technical Field

[0001] This utility model relates to the field of pipeline support structure technology, specifically a pipeline seismic support structure. Background Technology

[0002] In vacuum applications, it is often necessary to provide supporting structural components for vacuum chamber piping or valves. Under certain conditions, vacuum system piping needs to be connected to vacuum valves; this necessitates considering the issue of fixed support for the piping.

[0003] For example, the national authorized patent announcement number CN208311667U discloses a pipeline support structure component, including a support rod. An upper support pipe is slidably connected to the upper part of the support rod, and a support plate is fixedly connected to the upper end of the upper support pipe. A lower support pipe is slidably connected to the lower part of the support rod, and a fixing flange is fixedly connected to the lower end of the lower support pipe. The beneficial effects of this utility model are: it has the characteristics of simple structure, convenient processing and manufacturing, and wide application range; it can be used as a fixed support for all vacuum pipelines and valves; it has a large adjustment range, which can solve the problem of insufficient length when supporting pipelines; it can solve the problem of fixing the support structure component to the base plate after vacuum pipeline installation; it has strong versatility; and it is convenient for disassembly and maintenance.

[0004] However, the aforementioned pipeline support structure components only achieve height adjustment through the sliding connection between the support rod and the support pipe, without any anti-vibration buffer or restraint structure. When vibration is generated, the lateral / longitudinal impact force will be directly transmitted to the vacuum pipeline, which will lead to problems such as pipeline weld cracking, valve flange seal failure, and damage to the vacuum environment. Utility Model Content

[0005] The purpose of this utility model is to provide a pipeline seismic support structure to solve the problems mentioned in the background art, which are that the pipeline support structure components can only adjust the height, have no seismic buffer and restraint structure, and the lateral / longitudinal impact force generated by vibration is directly transmitted to the vacuum pipeline, which can easily lead to pipeline weld cracking, valve flange seal failure and vacuum environment damage.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A seismic support structure for pipelines includes: a mounting plate, a spring ring fixedly mounted on the upper inner surface of the mounting plate, a collar integrally formed at the central axis of the spring ring, a universal ball rotatably mounted inside the collar, connecting rods fixedly mounted on both the upper and lower surfaces of the universal ball, a pipe clamp fixedly mounted on the upper surface of the connecting rod, and an automatic calibration mechanism fixedly mounted on the lower surface of the connecting rod.

[0008] Preferably, the automatic calibration mechanism includes a counterweight, which is fixedly installed on the lower surface of the connecting rod, so that the counterweight, through its own gravity, can work in conjunction with the elastic support force of the upper spring ring to form a "gravity-elasticity" balance system.

[0009] Preferably, a magnetic ball is fixedly installed on the lower surface of the counterweight, the magnetic ball attracts the magnetic base, and the magnetic base is fixedly installed on the lower inner surface of the mounting plate through a connecting arm fixedly installed on the outer surface.

[0010] Preferably, the magnetic base and the magnetic ball below the counterweight form a "vertical opposing magnetic attraction", allowing the magnetic attraction to provide a continuous "downward traction positioning force", so as to firmly attract the counterweight to the initial vertical position and prevent it from shifting laterally due to slight vibration.

[0011] Preferably, a first connecting post is rotatably mounted on the upper surface of each connecting arm via a ball joint, and a second connecting post is slidably mounted inside the first connecting post in a damped manner. The other end of the second connecting post is also rotatably mounted on the outer surface of the counterweight via a ball joint.

[0012] Preferably, the first connecting column and the second connecting column are in a damped sliding fit, and the second connecting column is then connected to the counterweight through a ball joint to form "multiple sets of triangular support frames to limit the disorderly swaying of the counterweight".

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In static conditions, the vacuum pipeline is stably fixed by a three-dimensional balance system of "gravity-elasticity-magnetic force" and silicone rubber pads for pipe clamps, avoiding daily micro-vibration displacement and scratches on aluminum materials, and ensuring a vacuum sealing environment.

[0015] 2. During the dynamic seismic resistance phase, the gradual attenuation of magnetic attraction buffer, the energy absorption of damping connecting columns, and the limiting effect of the triangular frame work together to effectively weaken high-frequency impacts and disperse torsional stress, preventing pipeline weld cracking and flange failure.

[0016] 3. After an earthquake, relying on magnetic traction, counterweight gravity and damping reset, the vertical posture of the pipeline can be quickly and accurately restored, avoiding long-term offset damage. Moreover, the overall structure is adapted to the characteristics of vacuum and aluminum materials, taking into account both stability and practicality, and greatly improving the seismic safety and service life of vacuum pipelines.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-3 This utility model provides a technical solution:

[0023] like Figures 1-2 As shown, a pipeline seismic support structure includes: a mounting plate 1, a spring ring 101 fixedly mounted on the upper surface of the mounting plate 1, a collar 105 integrally formed at the central axis of the spring ring 101, a universal ball 104 rotatably mounted inside the collar 105, a connecting rod 103 fixedly mounted on both the upper and lower surfaces of the universal ball 104, a pipe clamp 102 fixedly mounted on the upper surface of the connecting rod 103, and an automatic calibration mechanism 2 fixedly mounted on the lower surface of the connecting rod 103.

[0024] Through the design of the mounting plate 1, spring ring 101, connecting rod 103, universal ball 104, collar 105, and automatic calibration mechanism 2, the mounting plate 1, as a basic load-bearing component, is fixedly connected to the building base or equipment frame, providing a stable installation benchmark for the entire support structure. The spring ring 101, fixed on its inner upper surface, is in an initial elastic state. The collar 105, integrally formed at the central axis, provides flexible restraint for the built-in universal ball 104. Simultaneously, the tube clamp 102 at the top of the connecting rod 103 clamps the vacuum tubing. The silicone rubber pad on the inner wall of the tube clamp 102 prevents scratches on the aluminum tubing, achieving tubing... During static fixing and position calibration of the pipeline, the automatic calibration mechanism 2 achieves initial balance through its own weight and the elastic support force of the spring ring 101, ensuring the pipeline maintains a vertical posture and preventing pipeline displacement caused by daily micro-vibrations. However, when dynamic loads such as earthquakes occur, lateral or longitudinal impact forces first act on the vacuum pipeline. The pipeline transmits the force to the upper connecting rod 103 through the pipe clamp 102, which in turn drives the universal ball 104 to rotate within the collar 105 to adapt to changes in the direction of the force. Simultaneously, the spring ring 101 undergoes elastic deformation under the impact force, absorbing the longitudinal impact force through the deformation process and weakening part of the vibration force transmission. The rear-lower automatic calibration mechanism 2 tends to shift under impact. Its own gravity and the magnetic attraction of the magnetic chuck component form a counter-constraint force, which, together with the elastic restoring force of the spring ring 101, constructs a three-dimensional balance system of "gravity-elastic force-magnetic force" to limit the pipeline offset. In addition, the 360° rotation characteristic of the universal ball 104 can prevent the impact force from concentrating in a fixed direction, reduce stress concentration at pipeline welds and valve flanges, and prevent seal failure. After the seismic load weakens or disappears, the spring ring 101, with its elastic reset function, pushes the collar 105 and the universal ball 104 back to their initial positions, thereby... The connecting rod 103 drives the clamp 102 and the pipeline to initially reset. The automatic calibration mechanism 2, under its own gravity and the magnetic attraction of the magnetic attraction component, further pulls the connecting rod 103 and the universal ball 104 to precisely reset, ensuring that the pipeline returns to a vertical position. Throughout the process, the rotational cooperation of the collar 105 and the universal ball 104, the elastic buffer of the spring ring 101, and the balancing reset function of the automatic calibration mechanism 2 work together to effectively resist vibration and ensure the sealing and structural integrity of the vacuum pipeline, avoiding pipeline damage and vacuum environment disruption caused by vibration.

[0025] like Figure 3As shown, the automatic calibration mechanism 2 includes a counterweight 204, which is fixedly installed on the lower surface of the connecting rod 103. The counterweight 204, through its own gravity, works in conjunction with the elastic support of the upper spring ring 101 to form a "gravity-elasticity" balance system. A magnetic ball 206 is fixedly installed on the lower surface of the counterweight 204. The magnetic ball 206 attracts the magnetic base 201, which is fixedly installed on the lower inner surface of the mounting plate 1 via a connecting arm 202 fixedly installed on its outer surface. The magnetic base 201 and the magnetic ball 206 below the counterweight 204 form a "vertical opposing magnetic attraction," allowing the magnetic attraction to provide a continuous "downward traction positioning force," firmly holding the counterweight 204 in its initial vertical position and preventing lateral displacement due to slight vibrations. Each set of connecting arms 202 has a first connecting post 203 mounted on its upper surface via a ball joint. A second connecting post 205 is slidably mounted inside the first connecting post 203 in a damped manner. The other end of the second connecting post 205 is also mounted on the outer surface of the counterweight 204 via a ball joint. The first connecting post 203 and the second connecting post 205 are in a damped sliding engagement. The second connecting post 205 is then connected to the counterweight 204 via a ball joint, forming multiple sets of triangular support frames that limit the disorderly swaying of the counterweight 204.

[0026] Through the design of the magnetic base 201, connecting arm 202, first connecting column 203, counterweight 204, second connecting column 205, and magnetic ball 206, in static installation and daily micro-vibration scenarios, the magnetic base 201 is fixedly connected to the mounting plate 1 via the connecting arm 202, forming a stable bottom support reference. Its "vertical opposing magnetic attraction" design with the magnetic ball 206 below the counterweight 204 continuously provides downward traction and positioning force. Combined with the weight of the counterweight 204 itself and the elastic support force of the spring ring 101, this further strengthens the three-dimensional balance system of "gravity-elasticity-magnetism," firmly adhering the counterweight 204 to its initial vertical position and preventing damage during daily equipment operation or minor vibrations. The lateral displacement caused by the movement can also avoid mechanical friction with related components of the aluminum pipeline through the non-contact characteristics of magnetic attraction, protecting the sealing environment of the vacuum pipeline and the oxide film on the surface of the aluminum material. When dynamic loads such as earthquakes are applied, if the pipeline is subjected to impact force and the counterweight 204 tends to shift, firstly, the magnetic attraction between the magnetic ball 206 and the magnetic base 201 will gradually decrease as the displacement distance increases. It will not transmit impact stress instantaneously like a rigid fixation, and it can provide initial buffering for the counterweight 204 through "gradually weakening magnetic constraint" to slow down the displacement speed. At the same time, the first connecting post 203 and the second connecting post 205 on the connecting arm 202, which are connected by a ball joint, respond quickly, allowing the counterweight 204 to shift. When the counterweight 204 shifts, it pushes the second connecting column 205 to slide in a damped manner within the first connecting column 203. The damping structure absorbs high-frequency impact energy through friction or fluid resistance, weakening the vibration waves generated by the earthquake. Furthermore, the "triangular support frame" formed by multiple sets of connecting columns and connecting arms 202 can limit the disorderly swaying of the counterweight 204 from different directions. Especially for torsional forces and oblique impact forces, the geometric stability of the frame can disperse stress, preventing the counterweight 204 from swinging around the connecting rod 103 in a large circular motion, thus protecting the vacuum pipeline welded joints and valve flanges. When the seismic load weakens or disappears, the magnetic ball 206, under the magnetic attraction of the magnetic base 201, will actively pull the counterweight 204. The counterweight 204 moves towards its initial vertical position. With its own weight, it accelerates the repositioning of the lower connecting rod 103 and the universal ball 104. At the same time, the damping sliding structure of the first connecting column 203 and the second connecting column 205 releases the stored elastic potential energy. Through the flexibility of the ball's rotation, it assists the counterweight 204 in correcting minor offset angles, ensuring its precise return to the initial position. The "triangular support frame" plays a guiding role in this process, preventing the counterweight 204 from swinging back and forth during repositioning. This further improves the efficiency and stability of pipeline repositioning, ultimately ensuring that the vacuum pipeline quickly returns to a safe operating state after the earthquake, avoiding sealing failure or structural damage caused by long-term offset.

[0027] Based on the above technical solution, the working steps of this solution are summarized as follows: The mounting plate 1, as the basic load-bearing component, is fixedly connected to the building base or equipment frame, providing a stable installation benchmark for the entire support structure. The spring ring 101 fixed on its inner upper surface is in an initial elastic state. Through the integrally formed collar 105 at the central axis, it flexibly limits the internal universal ball 104. Simultaneously, the pipe clamp 102 at the top of the upper connecting rod 103 clamps the vacuum pipeline. The silicone rubber pad on the inner wall of the pipe clamp 102 prevents scratches on the aluminum pipeline, achieving static fixation and position calibration of the pipeline. The magnetic base 201 is fixedly connected to the mounting plate 1 through the connecting arm 202, forming a stable bottom support benchmark. Its perpendicularity to the magnetic ball 206 below the counterweight 204... The "opposing magnetic attraction" design provides a continuous downward traction and positioning force. Combined with the weight of the counterweight 204 and the elastic support of the spring ring 101, this further strengthens the three-dimensional balance system of "gravity-elasticity-magnetism." This not only firmly holds the counterweight 204 in its initial vertical position, preventing lateral displacement caused by daily equipment operation or minor vibrations, but also avoids mechanical friction with aluminum tubing components due to the non-contact nature of magnetic attraction, protecting the vacuum tubing's sealing environment and the aluminum surface oxide film. When subjected to dynamic loads such as earthquakes, if the tubing is impacted and causes the counterweight 204 to shift, the magnetic attraction between the magnetic ball 206 and the magnetic base 201 gradually decreases with increasing displacement distance, unlike rigid fixation where the force is transmitted instantaneously. The impact stress can be initially buffered by the "gradually weakening magnetic confinement" of the counterweight 204, slowing down the offset speed. At the same time, the first connecting column 203 and the second connecting column 205 on the connecting arm 202, which are connected by a ball joint, respond quickly, allowing the counterweight 204 to push the second connecting column 205 to slide in a damped manner within the first connecting column 203 when offset. The damping structure absorbs high-frequency impact energy through friction or fluid resistance, weakening the vibration waves generated by the earthquake. Moreover, the "triangular support frame" formed by multiple sets of connecting columns and connecting arms 202 can limit the disorderly swaying of the counterweight 204 from different directions. Especially for torsional forces and oblique impact forces, the geometric stability of the frame can disperse stress and prevent the counterweight 204 from generating stress around the connecting rod 103. The large-scale circular swing protects the welded joints and valve flanges of the vacuum pipeline. When the seismic load weakens or disappears, the magnetic ball 206, under the magnetic attraction of the magnetic base 201, actively pulls the counterweight 204 towards its initial vertical position. Combined with the counterweight 204's own weight, this accelerates the repositioning of the connecting rod 103 and the universal ball 104. Simultaneously, the damping sliding structure of the first connecting column 203 and the second connecting column 205 releases stored elastic potential energy. Through the flexibility of the ball's rotation, it assists the counterweight 204 in correcting minor offset angles, ensuring its precise return to its initial position. The "triangular support frame" acts as a guide during this process, preventing the counterweight 204 from oscillating back and forth during repositioning, further improving the pipeline repositioning efficiency and stability.Ultimately, this ensures that the vacuum pipeline quickly returns to a safe operating state after the earthquake, preventing seal failure or structural damage caused by prolonged displacement.

[0028] In summary: Through the rotational engagement of the collar 105 and the universal ball 104, the elastic buffering of the spring ring 101, and the balancing and resetting effect of the automatic calibration mechanism 2, the vibration force is effectively resisted, and the sealing and structural integrity of the vacuum pipeline are ensured, thus avoiding pipeline damage and vacuum environment disruption caused by vibration.
