Description

Technical Field

[0001] This invention belongs to the technical field of pipeline installation equipment, and specifically provides a pipeline support and hanger and its assembly method. Background Technology

[0002] In the field of pipeline installation, pipeline vibration and noise are among the key concerns in various projects. Existing methods for addressing pipeline vibration involve installing flexible supports and hangers. However, traditional flexible supports and hangers can only reduce the transmission of broadband vibration energy; they cannot weaken the lateral amplitude spectrum vibration inherent in the pipeline itself. Because the lateral amplitude spectrum vibration of the pipeline causes the spring supports and hangers to transmit the vibration to the installation foundation, it affects the vibration reduction effect of the supports and hangers on the pipeline. Simultaneously, it places more stringent demands on the reliability of the pipeline's lateral fixing components, impacting pipeline safety.

[0003] In order to effectively reduce the line spectrum vibration of the controlled system, metal spring oscillator vibration absorbers are usually used to control the energy transfer. This requires that the installation and arrangement of the springs be carefully considered during the design process. The overall structural adaptability is poor, and the overall space occupied after installation is large and the system integration is low, which limits the application of vibration absorption technology in the field of transverse line spectrum control of pipelines.

[0004] Therefore, there is an urgent need for an integrated pipe support with lateral line spectrum control function to solve the above problems. Summary of the Invention

[0005] One object of the present invention is to provide an integrated pipe support with lateral line spectrum control function.

[0006] To achieve the above objectives, the present invention provides a pipe support bracket, comprising:

[0007] A vibration-absorbing module is used to receive the vibration generated by the pipeline. It includes a counterweight shell and a first connecting rod. The counterweight shell has a receiving space. The two ends of the first connecting rod are respectively connected to the first end of the counterweight shell and the pipeline.

[0008] A vibration isolation module for reducing the transmission of vibration includes a second connecting rod and an elastic component. The second connecting rod passes through the second end of the counterweight shell. The elastic component is disposed within the receiving space and is connected to the second connecting rod. The elastic component is configured to be able to drive the second connecting rod to move relative to the counterweight shell along its guiding direction when subjected to force.

[0009] Furthermore, the elastic component includes a connecting plate and a spring, the connecting plate being disposed within the receiving space and connected to the second connecting rod, and the spring being disposed between the connecting plate and the second end of the counterweight shell.

[0010] Furthermore, the counterweight shell includes a cover plate, a bottom plate, and a shell. The cover plate is connected to one end of the shell, and a through hole is provided on the cover plate. The second connecting rod can pass through the through hole, and the spring is disposed between the cover plate and the connecting plate. The bottom plate is connected to the other end of the shell, and the first connecting rod is connected to the bottom plate.

[0011] Furthermore, the elastic element is configured as a spring, disc spring, or leaf spring.

[0012] Furthermore, the elastic element is configured as a cylindrical spring, and both the cover plate and the connecting plate are provided with positioning blocks. The two ends of the cylindrical spring are respectively connected to the positioning blocks on the cover plate and the positioning blocks on the connecting plate, so that the cylindrical spring extends along the guide direction of the second connecting rod.

[0013] Furthermore, the first connecting rod is integrally formed with the base plate; or, the base plate is provided with a second through hole, through which the first connecting rod passes and is fixedly connected to the base plate by fasteners.

[0014] Furthermore, the support bracket includes a fastening nut, the connecting plate is provided with a third through hole, the second connecting rod is provided with a threaded structure, the second connecting rod passes through the third through hole, and the nut is tightened with the threaded structure to fix the connecting plate and the second connecting rod together.

[0015] Furthermore, the cover plate and the housing, and the bottom plate and the housing are all detachably connected; and / or, the cross-section of the housing is cylindrical or square.

[0016] Furthermore, the first connecting rod includes a pipe clamp, the pipe clamp being disposed at one end of the first connecting rod away from the counterweight shell, the pipe clamp being used to connect to the pipeline; and / or, the second connecting rod includes a connecting portion, the connecting portion being disposed at one end of the second connecting rod away from the counterweight shell, the connecting portion being connected to the base of the support.

[0017] In other embodiments, a method for assembling a pipe support is provided, comprising assembling the pipe support as described above by the assembly method; the assembly method includes: detecting the maximum vibration frequency value of the pipe to be tested; calculating the mass of the required counterweight shell and the length of the first connecting rod based on the maximum vibration frequency value; and installing the support.

[0018] Furthermore, the step of calculating the required mass of the counterweight shell and the length of the first connecting rod based on the maximum vibration frequency value includes: calculating the mass m of the counterweight shell based on the maximum vibration frequency value f and the stiffness k of the first connecting rod, using the following formula: m = k / (2πf) 2Then, based on the stiffness k of the first connecting rod, the Young's modulus E of the first connecting rod, and the moment of inertia I of the first connecting rod section, the length L of the first connecting rod is calculated using the following formula: L 3 = (3EI) / k.

[0019] Further, the step of installing the support bracket includes: assembling the vibration-absorbing module; installing the assembled vibration-absorbing module onto the pipeline; installing an accelerometer on the cover plate of the counterweight shell; testing the vibration absorption frequency of the vibration-absorbing module using a hammer impact method; adjusting the relative position of the base plate of the counterweight shell and the first connecting rod according to the value detected by the accelerometer until the value detected by the accelerometer reaches the target value of the lateral vibration absorption frequency, at which point the installation of the vibration-absorbing module is complete; assembling the vibration isolation module; installing an accelerometer on the cover plate; testing the overall vibration absorption frequency of the support bracket using a hammer impact method; adjusting the relative position of the base plate and the first connecting rod according to the value detected by the accelerometer during the hammer impact and the target value of the overall vibration absorption frequency of the support bracket, at which point the installation of the support bracket is complete.

While achieving transverse line spectrum control, it improves the system's integration and has the advantage of requiring less installation space, effectively solving the transverse line spectrum vibration problem existing in the field of pipeline vibration control.

Since such less related technical features are common knowledge in the field, the omission of such less related features will not result in insufficient disclosure of this invention.

[0033] like Figure 1 and 2 As shown, in some embodiments of the present invention, a pipe support 100 is provided, including a vibration absorption module and a vibration isolation module. The vibration absorption module is used to receive vibrations generated by the pipe and control the transverse line spectrum. The vibration absorption module includes a counterweight shell and a first connecting rod 9. The counterweight shell has a receiving space, and the two ends of the first connecting rod 9 are respectively connected to the first end m of the counterweight shell and the pipe. The vibration isolation module is used to weaken the transmission of vibrations. The vibration isolation module includes a second connecting rod 1 and an elastic component. The second connecting rod 1 passes through the second end n of the counterweight shell. The elastic component is disposed in the receiving space and is connected to the second connecting rod 1. The elastic component is configured to be able to drive the second connecting rod 1 to move relative to the counterweight shell along its guiding direction when subjected to force, so as to weaken the vibrations received by the vibration absorption module by moving the second connecting rod 1 in its guiding direction through the vibration of the elastic element 3.

[0034] It should be noted that, compared with traditional elastic supports 100 or pipeline vibration absorbers, this invention is the first to integrate the counterweight shell of the support 100 as both the additional mass for vibration absorption and the vibration transmission component. It has a high degree of integration and occupies little space. While maintaining the broadband vibration reduction effect of traditional supports, it also has the ability to control the transverse line spectrum vibration of the pipeline, thus solving the drawback of traditional elastic supports being unable to control the low-frequency line spectrum of the pipeline.

[0035] The elastic component includes a connecting plate 5 and an elastic element 3. The connecting plate 5 is disposed within the receiving space and connected to the second connecting rod 1. The elastic element 3 is disposed between the connecting plate 5 and the second end n of the counterweight shell. The connecting plate 5 is fixedly connected to the second connecting rod 1, so that the second connecting rod 1 can move along its guiding direction during the compression or stretching of the elastic element 3. Of course, those skilled in the art can also configure the second connecting rod 1 and the connecting plate 5 to be integrally formed as needed.

[0036] Among them, the elastic element 3 can be set as a spring, disc spring, leaf spring or other elastic element that can produce an elastic effect.

[0037] Preferably, the elastic element 3 is configured as a cylindrical spring.

[0038] The counterweight shell includes a cover plate 2, a base plate 8, and a shell 4. The cover plate 2 is connected to one end of the shell 4. A first through hole 21 is provided on the cover plate 2, through which a second connecting rod 1 can pass. An elastic element 3 is disposed between the cover plate 2 and the connecting plate 5. The base plate 8 is connected to the other end of the shell 4, and the first connecting rod 9 is connected to the base plate 8.

[0039] Both the cover plate 2 and the connecting plate 5 are provided with positioning blocks 7. The two ends of the cylindrical spring are connected to the positioning blocks 7 on the cover plate 2 and the positioning blocks 7 on the connecting plate 5 respectively, so that the cylindrical spring extends along the guide direction of the second connecting rod 1.

[0040] It should be noted that the base plate 8 and the first connecting rod 9 in this invention can be integrally formed. However, in order to improve the vibration damping effect of the support 100, the base plate 8 and the first connecting rod 9 are preferably set as detachable structures. When installing the base plate 8 and the first connecting rod 9, the relative position of the first connecting rod 9 and the base plate 8 can be adjusted to control the transverse line spectrum. Specifically, the base plate 8 is provided with a second through hole 81, and the first connecting rod 9 passes through the second through hole 81 and is fixedly connected to the base plate 8 by a fastening nut 6.

[0041] In this configuration, the cover plate 2 and the housing 4, as well as the base plate 8 and the housing 4, can be detachably connected. Specifically, the cover plate 2 is fixedly connected to the second end n of the housing 4. The base plate 8 is fixedly connected to the first end m of the housing 4. The fixed connection can be achieved through tenon joints, riveting, or fasteners. The fasteners can be screws or bolts.

[0042] The cross-section of the housing 4 can be circular or square, and the connecting plate 5 can be a disc structure or a square disc shape. Preferably, in this embodiment, the cross-section of the housing 4 is circular, the connecting plate 5 is circular, and the diameter of the connecting plate 5 is smaller than the diameter of the housing 4, while the diameter of the cover plate 2 is larger than the diameter of the connecting plate 5.

[0043] The support bracket 100 includes a fastening nut 6, a third through hole 51 on the connecting plate 5, and a threaded structure on the second connecting rod 1. The second connecting rod 1 passes through the third through hole 51, and the fastening nut 6 is tightened with the threaded structure to fix the connecting plate 5 and the second connecting rod 1.

[0044] The first connecting rod 9 includes a pipe clamp 10. The pipe clamp 10 is provided at the end of the first connecting rod 9 away from the counterweight shell. The pipe clamp 10 is used to connect to the pipeline.

[0045] The second connecting rod 1 includes a connecting part. The connecting part is provided at the end of the second connecting rod 1 away from the counterweight shell, and the connecting part is connected to the base of the support 100.

[0046] In other embodiments of the present invention, a method for assembling a pipe support 100 is provided, comprising assembling the pipe support 100 described above by means of the assembly method; the assembly method includes:

[0047] Step S110: Detect the maximum vibration frequency of the pipeline under test. A sensor is used to directly detect the vibration frequency of the pipeline under test during operation and determine its maximum vibration frequency value so that a suitable support 100 can be installed to reduce the vibration generated by the pipeline.

[0048] Step S120: Calculate the required mass of the counterweight shell and the length of the first connecting rod 9 based on the maximum vibration frequency value. The parameters of the components within the vibration-absorbing module connected to the pipeline are adjusted according to the specific vibration frequency of the pipeline under test, resulting in better vibration damping effect of the support 100. Research has shown that adjusting the length of the first connecting rod 9 and the weight of the counterweight shell helps control the lateral propagation of vibration. Therefore, this invention determines the relevant parameters of the first connecting rod 9 and the counterweight shell by determining the vibration frequency of the pipeline, and specifically generates vibration-adaptive supports 100 for different pipelines. Specifically, step S120 includes:

[0049] Step S121: Based on the maximum vibration frequency value f and the stiffness k of the first connecting rod 9, the mass m of the counterweight shell is calculated using the following formula:

[0050] m = k / (2πf) 2 ;

[0051] Step S121: Based on the stiffness k, Young's modulus E, and moment of inertia I of the first connecting rod 9, the length L of the first connecting rod 9 is calculated using the following formula:

[0052] L 3 = (3EI) / k.

[0053] Step S130: Install the support bracket 100. Since the parameters of the first connecting rod 9 and the counterweight shell can affect the vibration damping effect of the support bracket 100, operators further discovered that adjusting the relative position of the first connecting rod 9 and the base plate 8 also affects the control of the lateral vibration frequency by the vibration absorption module. Therefore, this invention adjusts the installation position of the first connecting rod 9 and the base plate 8 by testing the vibration damping capabilities of the vibration absorption module and the vibration isolation module, thereby configuring the support bracket 100 required for different pipelines. Specifically, step S130 includes:

[0054] Step 131: Assemble the vibration absorption module. First, pass the first connecting rod 9 through the second through hole 81 on the base plate 8, and then tighten the thread and nut on the first connecting rod 9. Next, install the housing 4 on the base plate 8 with screws, and finally fix the cover plate 2 to the housing 4 with screws to complete the assembly of the vibration absorption module.

[0055] Step 132: Install the assembled vibration-absorbing module onto the pipeline. Install an accelerometer on the cover plate 2 of the counterweight shell. Test the vibration absorption frequency of the vibration-absorbing module using the hammer impact method. Based on the value detected by the accelerometer, adjust the relative position of the base plate 8 of the counterweight shell and the first connecting rod 9 until the value detected by the accelerometer reaches the target value of the lateral vibration absorption frequency. The installation of the vibration-absorbing module is then complete. The target value of the lateral vibration absorption frequency can be obtained based on the operator's experience from multiple trials, or through experimental testing by the operator.

[0056] Step 133: Assemble the vibration isolation module. First, remove the cover plate 2. Then, pass the second connecting rod 1 through the third through hole 51 on the cover plate 2 and the first through hole 21 on the connecting plate 5 in sequence, and tighten the thread on the second connecting rod 1 to the nut. Next, install the elastic element 3 between the cover plate 2 and the connecting plate 5. After positioning, use the fastening nut 6 to fix the position of the connecting plate 5. Finally, install the cover plate 2 back to the original position of the counterweight shell and fix it with screws to complete the installation of the vibration isolation module.

[0057] Step 134: Install an acceleration sensor on the cover plate 2 and use the hammer impact method to test the overall vibration absorption frequency of the support 100. Based on the value detected by the acceleration sensor during the hammer impact and the target value of the overall vibration absorption frequency of the support 100, adjust the relative position of the base plate 8 and the first connecting rod 9 until the value detected by the acceleration sensor is the same as the target value of the overall vibration absorption frequency of the support 100. Then the support 100 is installed.

[0058] Those skilled in the art will understand that this invention receives vibrations generated by the pipeline through a vibration-absorbing module, controls the transverse vibration spectrum, and then weakens the vibration through a vibration isolation module, so that the vibrations generated by the pipeline have little or no impact on the installation foundation of the support 100. The support 100 of this invention introduces dynamic vibration absorption technology, integrating its subsystem mass with the pipeline support shell, achieving transverse vibration spectrum control while significantly increasing the system's integration, offering the advantage of smaller installation space, and effectively solving the transverse vibration spectrum problem existing in the field of pipeline vibration control.
