Description

Technical Field

[0001] This invention belongs to the field of heat exchanger unit pipeline support technology, specifically referring to a heat exchanger unit pipeline support frame. Background Technology

[0002] During operation, the internal piping system of a heat exchanger unit is subjected to various complex loads:

[0003] 1. Vibration: Originating from the operating vibration of equipment such as pumps and compressors, long-term exposure can easily lead to loosening of pipe joints and fatigue cracking of supporting structures;

[0004] 2. Thermal displacement: Due to the temperature change of the medium inside the pipeline, the pipeline itself will undergo significant thermal expansion and contraction. If the supporting structure is rigidly constrained, huge thermal stress will be generated inside the pipeline, affecting the sealing performance and service life.

[0005] 3. Fluid impact: The start-up, shutdown and flow rate changes of the medium can cause water hammer or pressure fluctuations, which can cause instantaneous impacts on the pipeline.

[0006] Existing pipe support systems mostly use simple angle steel or channel steel welded into rigid brackets, or use fixed pipe clamps to lock the pipes in place. While these structures are simple to manufacture, they cannot effectively absorb vibrations and severely restrict the thermal displacement of the pipes, which is the root cause of the aforementioned problems. Although some simple spring-loaded shock absorbers exist, their function is limited, usually only providing buffering in one direction (usually the vertical direction), unable to cope with the complex movements of pipes in three-dimensional space, and lacking the ability to guide and adapt to thermal displacement.

[0007] Therefore, there is an urgent need in this field for an integrated support solution that can simultaneously address vibration, shock, and thermal displacement issues. Summary of the Invention

[0008] In order to overcome the shortcomings of the prior art, the present invention provides a heat exchanger unit pipeline support frame with multi-dimensional buffering and thermal displacement adaptive functions. The support frame can effectively attenuate vibration and impact in both vertical and horizontal directions, and can guide and adapt to the axial displacement of the pipeline caused by thermal expansion and contraction, thereby significantly reducing the stress level of the pipeline system and improving operational safety and reliability.

[0009] The technical solution adopted by the present invention is as follows: The present invention provides a heat exchanger unit pipeline support frame, including a base, a pipe clamp assembly, and a multi-dimensional buffer and adaptive mechanism connected between the two. The multi-dimensional buffer and adaptive mechanism includes a vertical buffer module and a horizontal buffer and thermal displacement adaptive module. The vertical buffer module is disposed on the base, and the horizontal buffer and thermal displacement adaptive module is disposed between the vertical buffer module and the pipe clamp assembly.

[0010] Furthermore, the horizontal buffer and thermal displacement adaptive module includes a horizontal buffer component and a thermal displacement adaptive component. The horizontal buffer component is disposed on the vertical buffer module, and the thermal displacement adaptive component is disposed on the horizontal buffer component. The horizontal buffer component includes a lower connecting plate, a locking slider, and a horizontal sliding platform. The lower connecting plate is disposed on the vertical buffer module, the locking slider is locked and slidably disposed on the lower connecting plate, and the horizontal sliding platform is connected to the locking slider.

[0011] Preferably, the upper wall of the lower connecting plate is provided with a locking groove, and the locking slider is locked and slidably disposed in the locking groove, with the upper wall of the locking slider being at the same height as the upper wall of the lower connecting plate.

[0012] Furthermore, the thermal displacement adaptive component includes a guide post, a butterfly spring assembly, and an upper limit plate. The guide post is disposed on a horizontal sliding platform, and the butterfly spring assembly is sleeved on the guide post. A gap is left between the butterfly spring assembly and the guide post to ensure that the butterfly spring assembly can deform freely and efficiently, while preventing it from tipping over and becoming unstable in extreme cases. The upper limit plate is provided with a guide hole, and the upper limit plate is sleeved on the guide post through the guide hole. The diameter of the guide hole is larger than the diameter of the guide post. The butterfly spring assembly is disposed between the horizontal sliding platform and the upper limit plate to provide radial buffering and restoring capability on the horizontal plane.

[0013] The horizontal sliding platform has a spherical groove on its upper wall, and the upper limit plate has a pressure hole.

[0014] Furthermore, the vertical buffer module includes a sleeve, a viscous damper, an upper pressure plate, and a main bearing spring. The sleeve is mounted on the base, the viscous damper is located inside the sleeve, and the viscous damper is coaxially fixed to the inner bottom surface of the sleeve. The upper pressure plate is connected to the telescopic end of the viscous damper, and the main bearing spring is sleeved on the outer side of the viscous damper. One end of the main bearing spring is located on the inner bottom surface of the sleeve, and the other end of the main bearing spring is located on the bottom surface of the upper pressure plate.

[0015] As a further preferred embodiment of the present invention, guide rods are provided on both sides of the bottom wall of the upper pressure plate, and telescopic holes are provided on the sleeve, with the guide rods telescopically sliding in the telescopic holes.

[0016] Furthermore, the pipe clamp assembly includes an upper pipe clamp, a lower pipe clamp, a cylindrical rod, a spherical boss, and bolts. The spherical boss is rotatably disposed within a spherical groove, and the two together form a spherical pair. The cylindrical rod is disposed on the spherical boss. The lower pipe clamp is connected to the cylindrical rod, and the upper pipe clamp is connected to the lower pipe clamp via bolts, thus clamping the pipe tightly in the middle.

[0017] The upper and lower pipe clamps have an anti-slip layer on their inner circumferential walls.

[0018] Furthermore, the base is provided with an elongated hole to facilitate fine-tuning of the installation position on site.

[0019] The beneficial effects achieved by the present invention using the above structure are as follows:

[0020] 1. Multidimensional vibration reduction: Through the combination of vertical buffer modules (spring + damper) and horizontal buffer modules (butterfly spring group), it realizes all-round and multi-dimensional buffering and absorption of vertical, horizontal radial and fluid impacts, effectively isolating the transmission of equipment vibration to pipelines, and pipeline vibration to foundation;

[0021] 2. Thermal displacement self-adaptation: Through a specially designed horizontal sliding platform and engaging slider, a low-friction, precisely guided degree of freedom is provided for the axial thermal expansion and contraction of the pipeline, completely avoiding the thermal stress problem caused by rigid constraints. This mechanism actively adapts to rather than restricts the deformation of the pipeline.

[0022] 3. Automatic self-alignment and anti-eccentricity: The innovative spherical pair design allows the pipe clamp assembly to self-adaptively deflect slightly, ensuring a perfect fit between the pipe clamp and the pipe surface, avoiding localized stress concentration caused by misalignment during installation, and also making the force on the support frame more even.

[0023] 4. Functional integration and synergy: This invention highly integrates four major functions—vibration reduction, impact resistance, thermal displacement self-adaptation, and automatic self-alignment—into a compact mechanical structure. The modules work together to form an intelligent pipeline support system, and its overall technical effect is far beyond the simple summation of individual functional components.

[0024] 5. Purely mechanical structure, high reliability: The entire support frame requires no external power or complex control, relying entirely on a sophisticated mechanical structure to achieve all functions. It is robust, maintenance-free, and has a long service life, making it particularly suitable for industrial environments. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0043] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the present invention provides a heat exchanger unit pipeline support frame, including a base 1, a pipe clamp assembly 2, and a multi-dimensional buffer and adaptive mechanism 3 connected between the two; the base 1 is provided with an elongated hole 30 to facilitate fine adjustment of the installation position on site.

[0044] like Figure 1 , Figure 6 As shown, the multidimensional buffering and adaptive mechanism 3 includes a vertical buffer module 4 and a horizontal buffering and thermal displacement adaptive module 5. The vertical buffer module 4 is mounted on the base 1, and the horizontal buffering and thermal displacement adaptive module 5 is located between the vertical buffer module 4 and the pipe clamp assembly 2. The vertical buffer module 4 includes a sleeve 18, a viscous damper 19, an upper pressure plate 20, and a main bearing spring 21. The sleeve 18 is mounted on the base 1, and the viscous damper 19 is located within the sleeve 18. 9 is coaxially fixed on the inner bottom surface of the sleeve 18. The upper pressure plate 20 is connected to the telescopic end of the viscous damper 19. The main bearing spring 21 is sleeved on the outside of the viscous damper 19. One end of the main bearing spring 21 is located on the inner bottom surface of the sleeve 18, and the other end of the main bearing spring 21 is located on the bottom surface of the upper pressure plate 20. Guide rods 22 are provided on both sides of the bottom wall of the upper pressure plate 20. The sleeve 18 is provided with telescopic holes 23. The guide rods 22 are telescopically slidably located in the telescopic holes 23.

[0045] like Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13As shown, the horizontal buffer and thermal displacement adaptive module 5 includes a horizontal buffer component 6 and a thermal displacement adaptive component 7. The horizontal buffer component 6 is mounted on the vertical buffer module 4, and the thermal displacement adaptive component 7 is mounted on the horizontal buffer component 6. The horizontal buffer component 6 includes a lower connecting plate 8, a locking slider 9, and a horizontal sliding platform 10. The lower connecting plate 8 is mounted on the vertical buffer module 4, and the locking slider 9 is locked and slidably mounted on the lower connecting plate 8. The horizontal sliding platform 10 is connected to the locking slider 9. The upper wall of the lower connecting plate 8 is provided with a locking groove 11, and the locking slider 9 is locked and slidably mounted in the locking groove 11. The upper wall of the locking slider 9 is at the same height as the upper wall of the lower connecting plate 8. The thermal displacement adaptive component 7 includes a guide post 12, a butterfly spring assembly 13, and an upper limit plate 14. The guide post 12 is mounted on the horizontal sliding platform 10, and the butterfly spring assembly 13 is sleeved on the guide post 12. A gap is left between the spring assembly 13 and the guide post 12 to ensure that when the disc spring assembly 13 is under maximum load, its inner hole will not contact the guide post 12, thereby avoiding the impact on buffering performance, energy consumption, or abnormal noise due to friction. This allows the guide post 12 to provide timely limit when the disc spring assembly 13 may buckle, playing a guiding role in preventing instability, while not interfering with the normal elastic buffering function of the spring. The upper limit plate 14 is provided with a guide hole 15, and the upper limit plate 14 is sleeved on the guide post 12 through the guide hole 15. The diameter of the guide hole 15 is larger than the diameter of the guide post 12. The disc spring assembly 13 is located between the horizontal sliding platform 10 and the upper limit plate 14 to provide radial buffering and reset capability on the horizontal plane. The upper wall of the horizontal sliding platform 10 is provided with a spherical groove 16, and the upper limit plate 14 is provided with a pressure hole 17.

[0046] like Figure 1 , Figure 11 , Figure 14 As shown, the pipe clamp assembly 2 includes an upper pipe clamp 24, a lower pipe clamp 25, a cylindrical rod 26, a spherical boss 27, and a bolt 28. The spherical boss 27 is rotatably disposed in the spherical groove 16, and the two together form a spherical pair. The cylindrical rod 26 is disposed on the spherical boss 27. The lower pipe clamp 25 is connected to the cylindrical rod 26. The upper pipe clamp 24 is connected to the lower pipe clamp 25 through the bolt 28, which clamps the pipe tightly in the middle. The inner circumferential walls of the upper pipe clamp 24 and the lower pipe clamp 25 are provided with an anti-slip layer 29.

[0047] In practical use, the pipeline is fixed between the upper pipe clamp 24 and the lower pipe clamp 25 by bolts 28. The weight of the pipeline presses down on the lower pipe clamp 25, causing the lower pipe clamp 25 to move downwards, which in turn causes the cylindrical rod 26 to move downwards. The cylindrical rod 26 then moves downwards, causing the spherical boss 27 to move downwards. The spherical boss 27 then moves downwards, causing the horizontal sliding platform 10 to move downwards. The horizontal sliding platform 10 then moves downwards, causing the locking slider 9 to move downwards. The locking slider 9 then moves downwards, causing the lower connecting plate 8 to move downwards. The lower connecting plate 8 then moves downwards, causing the upper pressure plate 20 to move downwards. At this time, the main bearing spring 21 is compressed, providing static support in the vertical direction. When vertical vibrations from the pump or compressor are transmitted, the main bearing spring 21... Spring 21 will be further compressed or released. This reciprocating motion is strongly suppressed by the coaxial viscous damper 19. The piston inside the viscous damper 19 moves in the silicone oil, converting the mechanical energy of the vibration into heat energy and dissipating it, thereby quickly calming the vibration and preventing the support frame and pipeline from jumping. In the absence of horizontal radial external force, the preload of the disc spring assembly 13 keeps the pipe clamp assembly 2 stable in the center position through the spherical joint. When horizontal radial (perpendicular to the pipeline axis) vibration or impact is transmitted, the force attempts to push the horizontal sliding platform 10 to move horizontally through the pipe clamp assembly 2 and the spherical joint. At this time, the ball... The boss 27 will roll or slide slightly within the spherical groove 16, causing the cylindrical rod 26 to press against the upper limit plate 14. The upper limit plate 14 converts this horizontal force into a compressive force on one side of the butterfly spring assembly 13. At this time, the butterfly spring assembly 13 undergoes compression deformation, absorbing energy. When the horizontal impact force disappears, the compressed butterfly spring assembly 13 releases its stored elastic potential energy, pushing the upper limit plate 14 back to its initial position, and then resetting the pipe clamp assembly 2 through the spherical joint. The guide post 12 ensures that the butterfly spring assembly 13 can only undergo compression deformation and will not bend or become unstable, and the horizontal slide remains stationary; when the pipeline When axial displacement occurs due to thermal expansion and contraction, the horizontal sliding platform 10 will be pushed to slide smoothly along the engaging groove 11 through the pipe clamp assembly 2 and the spherical pair. During this process, the disc spring assembly 13 hardly deforms and slides with almost zero resistance, thus perfectly releasing thermal stress. When there is an installation alignment error or a slight bend in the pipeline, the spherical pair allows the entire pipe clamp assembly 2 to rotate slightly in any direction relative to the horizontal sliding platform 10, ensuring that the inner wall of the pipe clamp assembly 2 is in full contact with the outer wall of the pipeline and avoiding dangerous edge loads. The above is the specific working process of this invention. This step can be repeated for the next use.
