Description

Technical Field

[0001] This utility model belongs to the field of pipeline support technology, specifically relating to a nonlinear elastic support structure for pipelines. Background Technology

[0002] In industrial production and construction engineering, pipelines, as the core components for transporting media (such as fluids and gases), are prone to vibration during operation due to factors such as media flow pulsation, equipment vibration transmission, and changes in ambient temperature. If vibration is not effectively controlled, it can not only cause noise pollution, but also lead to loosening of pipe joints, cracking of welds, and even fatigue damage to the pipeline, seriously affecting the safe and stable operation of the system.

[0003] In existing technologies, elastic support structures with vibration damping functions are typically used to support pipelines. However, conventional elastic support structures employ a fixed linear stiffness design, which makes it difficult to adapt to the dynamic changes in pipeline vibration characteristics under complex operating conditions such as fluctuations in medium flow rate and sudden temperature changes, thus limiting the vibration damping effect. Furthermore, existing elastic support structures lack targeted limiting mechanisms, making pipelines prone to excessive displacement or even detachment from the support structure during sudden vibrations, posing safety hazards. Utility Model Content

[0004] This utility model provides a nonlinear elastic support structure for pipelines, which aims to improve the adaptability of the support structure to pipeline vibration under different working conditions and improve the vibration reduction effect.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A nonlinear elastic support structure for a pipeline is provided, including a mounting base, a first clamping member, a second clamping member, elastic clamping blocks, limiting protrusions, and a locking member; the first clamping member has a first semi-circular space; the second clamping member is disposed above the first clamping member, and a second semi-circular space is formed in the second clamping member; after the second clamping member and the first clamping member are engaged, the second semi-circular space and the first semi-circular space enclose a clamping space for the pipeline to pass through; multiple elastic clamping blocks are provided, each elastic clamping block being evenly distributed in the first and second semi-circular spaces, used to abut against the sidewall of the pipeline and provide damping for the nonlinear vibration of the pipeline; multiple limiting protrusions are provided, each limiting protrusion being evenly distributed on the first and second clamping members, each limiting protrusion having a limiting end extending towards the pipeline, each limiting protrusion being used to limit excessive displacement of the pipeline; the locking member locks the engaged first and second clamping members onto the mounting base.

[0006] In one possible implementation, the first clamping member includes two lower clamping blocks; the two lower clamping blocks are spaced apart, and each of the two lower clamping members has a first inclined surface at one end that is close to each other; each of the first inclined surfaces has a first groove for mounting the elastic clamping block; after the two lower clamping blocks are mounted on the mounting base, they enclose the mounting base to form a first semi-circular space.

[0007] In some embodiments, each lower clamping block is provided with a limiting protrusion; wherein, the limiting protrusion corresponding to each lower clamping block includes two lower protrusions, which are respectively disposed on both sides of the lower clamping block along the length direction of the pipe.

[0008] For example, the second clamping member includes an upper clamping block with a trapezoidal groove forming a second semi-circular space; the trapezoidal groove has two second inclined surfaces; each second inclined surface has a second groove for mounting the elastic clamping block; the upper clamping block forms two ends corresponding to the two lower clamping blocks respectively.

[0009] For example, the upper clamping block is provided with two limiting protrusions, and the two limiting protrusions correspond one-to-one with the positions of the two second inclined surfaces; each limiting protrusion in the upper clamping block includes two upper protrusions, and two lower protrusions are respectively arranged on both sides of the upper clamping block along the length of the pipe.

[0010] In one possible implementation, the locking element includes threaded rods and limiting nuts; there are two threaded rods, both of which pass through the mounting base; two lower clamping blocks are slidably disposed on the two threaded rods respectively; the two ends of the upper clamping block are slidably engaged with the two threaded rods respectively; there are two limiting nuts, both of which abut against the mounting base and are threadedly connected to the two threaded rods respectively.

[0011] In some embodiments, the locking element further includes multiple washers fitted onto the threaded rod and located between the upper clamping block and the lower clamping block.

[0012] For example, the elastic clamping block is made of a high-temperature resistant viscoelastic material.

[0013] For example, the end face of the elastic clamping block that clamps the pipe is provided with anti-slip texture.

[0014] In one possible implementation, a buffer layer is provided on the limiting bump.

[0015] The beneficial effects of the nonlinear elastic support structure for pipelines provided by this utility model are as follows: Compared with the prior art, this utility model, by setting a first clamping member with a first semi-circular space and a second clamping member with a second semi-circular space that mates with the first clamping member, together with the mounting base, forms a clamping space for the pipeline. Multiple elastic clamping blocks evenly distributed within the two semi-circular spaces can specifically provide damping for the nonlinear vibration of the pipeline, adapting to the dynamic changes in the vibration characteristics of the pipeline under complex working conditions, and improving the vibration reduction limitations of traditional fixed linear stiffness supports. Multiple limiting protrusions evenly distributed on the first and second clamping members and having limiting ends extending towards the pipeline can effectively limit excessive displacement of the pipeline and prevent the pipeline from detaching from the support structure. The locking member can stably lock the mated first and second clamping members onto the mounting base, ensuring the reliability of the overall support, thereby reducing noise pollution caused by vibration, reducing the risk of loosening of pipeline joints, weld cracking, and fatigue damage, and ensuring the safe and stable operation of the pipeline system.

[0020] Please refer to the following: Figures 1 to 4 The nonlinear elastic support structure for pipelines provided by this utility model will now be described. The nonlinear elastic support structure for pipelines includes a mounting base 10, a first clamping member, a second clamping member, an elastic clamping block 40, a limiting protrusion 50, and a locking member 60. The first clamping member has a first semi-circular space. The second clamping member is positioned above the first clamping member and has a second semi-circular space. After the second clamping member and the first clamping member are engaged, the second semi-circular space and the first semi-circular space enclose a clamping space through which the pipeline 70 passes. The elastic clamping block 40 has multiple... Each elastic clamping block 40 is evenly distributed in the first semi-circular space and the second semi-circular space, used to abut against the side wall of the pipe 70 and provide damping for the nonlinear vibration of the pipe 70; multiple limiting protrusions 50 are provided, each limiting protrusion 50 is evenly distributed on the first clamping member and the second clamping member, each limiting protrusion 50 has a limiting end extending toward the pipe 70, each limiting protrusion 50 is used to limit the excessive displacement of the pipe 70; the locking member 60 locks the mating first clamping member and the second clamping member on the mounting base 10.

[0021] It should be noted that the pipe 70 passes through the clamping space enclosed by the first clamping member and the second semi-circular space, and the elastic clamping block 40 abuts against the side wall of the pipe 70 to form a flexible support. When the pipe 70 vibrates due to various factors, the elastic clamping block 40 provides damping for the nonlinear vibration of the pipe 70, consuming vibration energy to suppress vibration propagation. If the pipe 70 experiences a large amplitude vibration, the limiting end of the limiting protrusion 50 will contact the pipe 70, limiting the excessive displacement of the pipe 70 and preventing the pipe 70 from leaving the clamping space. The locking member 60 always maintains the engagement state of the first clamping member and the second clamping member, ensuring the clamping stability of the entire support structure for the pipe 70 and ensuring the continuous effectiveness of vibration reduction and limiting functions.

[0022] The beneficial effects of the nonlinear elastic support structure for pipelines provided by this utility model are as follows: Compared with the prior art, this utility model, by setting a first clamping member with a first semi-circular space and a second clamping member with a second semi-circular space that mates with the first clamping member, together with the mounting base 10, forms a clamping space for the pipeline 70. Multiple elastic clamping blocks 40 evenly distributed in the two semi-circular spaces can specifically provide damping for the nonlinear vibration of the pipeline 70, adapting to the dynamic changes in the vibration characteristics of the pipeline 70 under complex working conditions, and improving the vibration reduction limitations of traditional fixed linear stiffness supports. Multiple limiting protrusions 50 evenly distributed on the first and second clamping members and having limiting ends extending towards the pipeline 70 can effectively limit the excessive displacement of the pipeline 70, preventing the pipeline 70 from detaching from the support structure. The locking member 60 can stably lock the mated first and second clamping members onto the mounting base 10, ensuring the reliability of the overall support, thereby reducing noise pollution caused by vibration, reducing the risk of loosening of pipeline 70 joints, weld cracking, and fatigue damage, and ensuring the safe and stable operation of the pipeline 70 system.

[0023] Please see Figures 2 to 4 The first clamping member includes two lower clamping blocks 20; the two lower clamping blocks 20 are spaced apart, and each of the two lower clamping members has a first inclined surface at one end that is close to each other; each of the first inclined surfaces has a first groove 21 for mounting the elastic clamping block 40; after the two lower clamping blocks 20 are mounted on the mounting base 10, they enclose the mounting base 10 to form a first semi-circular space.

[0024] It should be noted that the pipe 70 is placed within the first semi-circular space enclosed by the two lower clamping blocks 20 and the mounting base 10. The elastic clamping block 40, installed in the first groove 21, conforms to the side wall of the pipe 70 along the first inclined surface. After the second clamping member aligns with the lower clamping block 20, the elastic clamping block 40 stably abuts against the pipe 70. When the pipe 70 generates nonlinear vibration, the elastic clamping block 40 provides damping to dissipate vibration energy. The locking member 60 locks the aligned second clamping member and the two lower clamping blocks 20 onto the mounting base 10, maintaining the stability of the clamping space, and works with the limiting protrusion 50 to achieve the limiting function.

[0025] The spacing between the two lower clamping blocks 20 and the design of the first inclined surface allow the first groove 21 to accurately position the elastic clamping block 40, ensuring a more reasonable and even distribution of the elastic clamping blocks 40 and a tighter fit with the side wall of the pipe 70. The elastic clamping block 40 is fixed by the first groove 21, improving installation stability, preventing displacement during vibration, and further optimizing the nonlinear vibration reduction effect. The first semi-circular space structure formed by the lower clamping blocks 20 and the mounting base 10 is more regular, adapting to the shape of the pipe 70. Combined with the locking action of the locking element 60, this enhances the load-bearing stability of the overall support structure and reduces various risks caused by pipe 70 vibration.

[0026] The two lower clamping blocks 20 are separately configured. When the pipe 70 has an axial sliding tendency, the separate lower clamping blocks 20 can adapt to the sliding requirements and ensure support stability. The two separate lower clamping blocks 20 can independently fine-tune their posture according to the axial sliding tendency of the pipe 70, avoiding the rigid constraint of the integral clamping component on the axial displacement of the pipe 70 and reducing the additional stress generated by the axial force on the pipe 70. The separate design allows each lower clamping block 20 to continuously adhere to the side wall of the pipe 70 through the elastic clamping block 40 in the first inclined surface and the first groove 21, ensuring that the damping effect of the elastic clamping block 40 is not interrupted during the axial sliding process, and the vibration reduction function is stably performed. The independent lower clamping blocks 20 can respectively bear the force brought by the axial sliding of the pipe 70, and the load is evenly distributed by the cooperation of the locking component 60 and the mounting base 10, avoiding the clamping loosening caused by local force concentration and preventing the pipe 70 from sliding too much axially. The separation structure can reduce frictional interference between the pipe 70 and the clamping parts when the pipe 70 slides axially, reduce the impact of sliding resistance on the normal operation of the pipe 70, and at the same time ensure the installation stability of the elastic clamping block 40 and prevent it from shifting due to axial friction.

[0027] Please see Figure 2 and Figure 3 Each lower clamping block 20 is provided with a limiting protrusion 50; wherein, the limiting protrusion 50 corresponding to each lower clamping block 20 includes two lower protrusions 51, and the two lower protrusions 51 are respectively arranged on both sides of the lower clamping block 20 along the length direction of the pipe 70.

[0028] It should be noted that the pipe 70 passes through the clamping space enclosed by the first and second semi-circular spaces, and the elastic clamping block 40 abuts against the side wall of the pipe 70 to provide vibration damping. When the pipe 70 exhibits radial vibration or axial sliding tendency, the lower protrusions 51 on both sides of the lower clamping block 20 will form contact limits with the surface of the pipe 70. The separated lower clamping block 20 can be finely adjusted according to the posture of the pipe 70, and the lower protrusions 51 on both sides always maintain an axial limiting posture for the pipe 70, preventing the pipe 70 from sliding excessively along its length. The locking member 60 locks the lower clamping block 20 and the second clamping member, ensuring the stability of the limiting position of the lower protrusions 51, and working together with the elastic clamping block 40 to achieve the dual functions of vibration damping and limiting.

[0029] Each lower clamping block 20 has lower protrusions 51 on both sides, forming a bidirectional limiting effect along the length of the pipe 70, precisely restricting excessive axial sliding of the pipe 70 and compensating for the shortcomings of single-direction limiting. The limiting protrusions 50 are adapted to the separate lower clamping blocks 20, and the lower protrusions 51 can synchronously adapt to the posture of the pipe 70 with the fine adjustment of the lower clamping blocks 20, avoiding rigid tension on the pipe 70 by the limiting structure. The two lower protrusions 51 are distributed on both sides of each lower clamping block 20, resulting in more even force distribution, reducing local pressure damage to the pipe 70, and ensuring the stability of the limiting process. The two lower protrusions 51 work together with the elastic clamping block 40 to limit the axial sliding of the pipe 70 without affecting the damping and vibration reduction effect, further improving the safety and reliability of the pipe 70 operation.

[0030] Please see Figures 2 to 4 The second clamping member includes an upper clamping block 30 with a trapezoidal groove forming a second semi-circular space; the trapezoidal groove has two second inclined surfaces; each second inclined surface has a second groove 31 for mounting the elastic clamping block 40; the upper clamping block 30 forms two ends corresponding to the two lower clamping blocks 20 respectively.

[0031] It should be noted that the pipe 70 is placed within the clamping space. The second groove 31 of the upper clamping block 30 and the first groove 21 of the lower clamping block 20 jointly position multiple elastic clamping blocks 40, ensuring that the elastic clamping blocks 40 abut against the sidewall of the pipe 70 from all directions. When the pipe 70 experiences nonlinear vibration, the upper and lower elastic clamping blocks 40 simultaneously provide damping, consuming vibration energy and achieving vibration reduction. The end of the upper clamping block 30 precisely corresponds to the lower clamping block 20. After locking with the locking element 60, the regularity of the clamping space is maintained, preventing the pipe 70 from shifting. When the pipe 70 experiences axial sliding or excessive radial displacement, the upper clamping block 30 and the lower clamping block 20 work together, the elastic clamping blocks 40 maintain a close fit, and the lower protrusion 51 provides a limit, doubly ensuring the stability of the pipe 70.

[0032] The trapezoidal groove forms a second semi-circular space that is more adaptable to the first semi-circular space, conforming to the shape of the pipe 70 and making the upper and lower elastic clamping blocks 40 more evenly distributed, resulting in a more balanced vibration reduction effect. The design of the second inclined surface and the second groove 31 makes the elastic clamping block 40 more stable to install, less prone to displacement during vibration, and enhances the fit with the side wall of the pipe 70, improving damping transmission efficiency. The ends of the upper clamping block 30 correspond one-to-one with the two lower clamping blocks 20, allowing for more precise force application during locking, avoiding localized force concentration, and enhancing the overall load-bearing stability of the support structure. The integrated upper clamping block 30, combined with the separate lower clamping blocks 20, simplifies the assembly process and, through coordinated upper and lower clamping, further restricts the radial vibration and axial sliding of the pipe 70, improving operational safety.

[0033] Please see Figure 2 and Figure 3The upper clamping block 30 is provided with two limiting protrusions 50, and the two limiting protrusions 50 correspond one-to-one with the positions of the two second inclined surfaces. Each limiting protrusion 50 in the upper clamping block 30 includes two upper protrusions 52 and two lower protrusions 51 are respectively arranged on both sides of the upper clamping block 30 along the length direction of the pipe 70.

[0034] It should be noted that the pipe 70 is located within the clamping space enclosed by the upper and lower clamping blocks 20, and the elastic clamping block 40 abuts against the sidewall of the pipe 70 in all directions, providing damping for nonlinear vibration. When the pipe 70 experiences excessive radial vibration, the upper protrusion 52 and the lower protrusion 51 work together to form a bidirectional blockage, limiting the radial displacement of the pipe 70. When the pipe 70 shows a tendency to slide axially, the upper protrusions 52 on both sides of the upper clamping block 30 and the lower protrusions 51 on both sides of the lower clamping block 20 cooperate to form a bidirectional limit along the length of the pipe 70. The upper clamping block 30 and the lower clamping block 20 are locked by the locking member 60. The upper protrusion 52 maintains a stable posture with the upper clamping block 30, while adapting to the fine-tuning action of the separate lower clamping block 20, always maintaining a reasonable limit distance with the pipe 70. The flexible support of the elastic clamping block 40 and the rigid limit of the upper and lower protrusions 51 do not interfere with each other, working together to achieve the dual functions of vibration reduction and anti-disengagement.

[0035] The upper protrusion 52 and lower protrusion 51 correspond vertically and are distributed bidirectionally along the length of the pipeline 70, forming a comprehensive limiting system that completely eliminates the risk of excessive radial vibration and excessive axial slippage of the pipeline 70. The limiting protrusions 50 correspond one-to-one with the second inclined surface, allowing the upper protrusion 52 to precisely fit the contour of the pipeline 70, avoiding localized compression damage to the pipeline 70 during limiting, and resulting in more uniform force distribution. The coordinated limiting by the upper and lower protrusions 51 compensates for the deficiencies of limiting in a single direction or position, further improving the stability of the pipeline 70's operation, while not affecting the damping and vibration reduction effect of the elastic clamping block 40. The upper protrusion 52 has strong structural adaptability with the separate lower clamping block 20 and the integrated upper clamping block 30, and can synchronously adapt with the micro-adjustment of the pipeline 70's posture, avoiding additional stress caused by rigid limiting and ensuring the long-term safe operation of the pipeline 70.

[0036] Please see Figure 2 The locking component 60 includes a threaded rod 61 and a limiting nut 62; there are two threaded rods 61, both of which pass through the mounting base 10; two lower clamping blocks 20 are slidably disposed on the two threaded rods 61 respectively; the two ends of the upper clamping block 30 are slidably engaged with the two threaded rods 61 respectively; there are two limiting nuts 62, both of which abut against the mounting base 10 and are threadedly connected to the two threaded rods 61 respectively.

[0037] It should be noted that when installing the pipe 70, the two lower clamping blocks 20 are aligned with the locking member 60 insertion holes on the mounting base 10, while the upper clamping block 30 is slid up on the threaded rod 61, so that the upper clamping block 30 and the lower clamping block 20 mate to form a clamping space that fits the pipe 70. After the elastic clamping block 40 is adjusted to press against the side wall of the pipe 70 according to the position of the upper and lower clamping blocks 20, the threaded rod 61 is fixed on the mounting base 10 by tightening the limiting nut 62, thereby locking the positions of the lower clamping block 20 and the upper clamping block 30 and maintaining the stability of the clamping space. When the pipe 70 vibrates or has a tendency to displace, the locking action of the threaded rod 61 and the limiting nut 62 ensures that the upper and lower clamping blocks 20 do not loosen, maintaining the damping effect of the elastic clamping block 40 and the limiting function of the limiting protrusion 50. The separate lower clamping blocks 20 slide independently on the threaded rod 61, which can respectively adapt to the local contour of the pipe 70, enhancing the fitting accuracy with the elastic clamping block 40.

[0038] The threaded engagement between the limiting nut 62 and the threaded rod 61 precisely locks the positions of the upper and lower clamping blocks 20, ensuring stable contact force between the elastic clamping block 40 and the pipe 70, and guaranteeing the continuity of the nonlinear vibration reduction effect. The two threaded rods 61 correspond to the two lower clamping blocks 20 respectively, allowing the lower clamping blocks 20 to be independently adjusted in position, working in conjunction with the upper clamping block 30 to form a clamping posture that conforms to the pipe 70, avoiding uneven clamping caused by minor deviations in the shape of the pipe 70. The overall locking structure is simple and reliable, easy to assemble and disassemble, facilitating the installation and subsequent maintenance of the pipe 70. Simultaneously, the rigid locking enhances the overall load-bearing capacity of the support structure, reducing the risk of structural loosening caused by vibration.

[0039] Please see Figure 2 The locking component 60 also includes a plurality of washers 63, which are sleeved on the threaded rod 61 and located between the upper clamping block 30 and the lower clamping block 20.

[0040] It should be noted that when adjusting the relative positions of the upper clamping block 30 and the lower clamping block 20, the clamping space height required for the pipe 70 diameter can be adapted by increasing or decreasing the number of shims 63 or selecting shims 63 of different thicknesses, ensuring that the elastic clamping block 40 can tightly abut against the side wall of the pipe 70. When the limit nut 62 is tightened, the shims 63 transmit pressure between the upper clamping block 30 and the lower clamping block 20, making the force more even and avoiding local compression deformation caused by direct contact. When the pipe 70 vibrates, the shims 63 can buffer the rigid impact between the upper clamping block 30 and the lower clamping block 20, reducing the relative wear caused by vibration and maintaining the stability of the locked state. The separated lower clamping block 20 and upper clamping block 30 are isolated by the shims 63, and their respective fine-tuning actions do not interfere with each other, ensuring that the elastic clamping block 40 always fits against the pipe 70, and the damping effect remains effective.

[0041] For example, the elastic clamping block 40 is made of a high-temperature viscoelastic material.

[0042] It should be noted that the elastic clamping blocks 40 are made of specified materials such as high-temperature resistant rubber and silicone rubber, and are installed in the first groove 21 of the first clamping member and the second groove 31 of the second clamping member. These elastic clamping blocks 40 are evenly distributed in the first and second semi-circular spaces, directly abutting against the side wall of the high-temperature medium pipeline 70, and together with the upper and lower clamping blocks 20, locking member 60, and limiting protrusion 50, form a complete support system. The selected material is adapted to the installation angles of the first and second inclined surfaces, ensuring a tight fit with the pipeline 70 even in high-temperature environments.

[0043] In the face of the working environment of the high-temperature medium pipeline 70, the selected high-temperature viscoelastic material can maintain structural stability at temperatures of 200℃ and above, without softening, degradation, or failure. When the pipeline 70 generates nonlinear vibration, this material absorbs and dissipates vibration energy through its own viscoelastic deformation, continuously providing stable damping and suppressing vibration propagation and noise generation. The locking component 60 fixes the positions of the upper and lower clamping blocks 20, ensuring that the elastic clamping block 40 of this material is always pressed against the pipeline 70. Under high-temperature conditions, it works in conjunction with the limiting protrusion 50 to ensure both vibration reduction and limit excessive displacement of the pipeline 70.

[0044] Please see Figure 2 and Figure 3 The end face of the elastic clamping block 40 that clamps the pipe 70 is provided with anti-slip texture 41.

[0045] It should be noted that when the pipe 70 is placed in the clamping space, the end face of the elastic clamping block 40 with the anti-slip texture 41 is tightly attached to the side wall of the pipe 70, increasing the frictional resistance with the surface of the pipe 70 through the texture. When the pipe 70 exhibits nonlinear vibration or axial sliding tendency, the anti-slip texture 41 effectively suppresses the relative sliding between the elastic clamping block 40 and the pipe 70, ensuring that the viscoelastic deformation of the elastic clamping block 40 accurately absorbs vibration energy and that the damping effect does not fail. The locking member 60 fixes the position of the upper and lower clamping blocks 20, keeping the elastic clamping block 40 with the anti-slip texture 41 in a tight state at all times. Combined with the limiting action of the limiting protrusion 50, this not only prevents the pipe 70 from slipping but also maintains a stable vibration reduction effect.

[0046] Please see Figure 2 and Figure 3 A buffer layer 53 is provided on the limiting protrusion 50.

[0047] It should be noted that when the pipe 70 experiences excessive radial vibration or excessive axial slippage, it first contacts the buffer layer 53 of the limiting protrusion 50. The buffer layer 53 absorbs the impact energy through its own deformation, preventing a rigid impact between the limiting protrusion 50 and the pipe 70. After deformation, the buffer layer 53 can still maintain the limiting function of the limiting protrusion 50, restricting further displacement of the pipe 70, while not affecting the viscoelastic damping effect of the elastic clamping block 40. The buffer layers 53 of the upper protrusion 52 and the lower protrusion 51 work together to synchronously buffer the impact during bidirectional limiting, and, in conjunction with the fine-tuning attitude of the separate lower clamping block 20, maintain flexible limiting contact with the pipe 70 at all times.

[0048] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
