[0002] In the field of pipeline installation, pipeline vibration and noise issues are one of the key issues in various projects. The existing method to solve pipeline vibration is to install elastic supports and hangers on the pipeline, but traditional elastic supports and hangers can only reduce the transmission of broadband vibration energy, and the lateral large-value line spectrum vibration of the pipeline itself cannot be weakened. Due to the lateral large-value line spectrum vibration of the pipeline, the spring supports and hangers will transmit the vibration to the installation foundation, thereby affecting the vibration reduction effect of the supports and hangers on the pipeline; at the same time, it will also bring more stringent tests to the reliability of the lateral fixings of the pipeline, affecting the safety of the pipeline.

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

The vibration isolation module is used to weaken the transmission of vibration. The vibration isolation module includes a second connecting rod 1 and an elastic component, and the second connecting rod 1 passes through the second end n of the counterweight shell. The elastic component is arranged in the containing space, and it is connected to the second connecting rod 1.

[0034] It should be noted that, compared with the traditional elastic support hanger 100 or pipeline vibration absorber, the present invention is the first to integrate the counterweight shell of the support hanger 100 as both a vibration-absorbing additional mass and a vibration isolation transmission component. It has a high degree of integration and occupies a small space. While maintaining the broadband vibration reduction effect of the traditional support hanger, it has the ability to control the lateral line spectrum vibration of the pipeline, which solves the problem that the traditional elastic hanger cannot control the low-frequency line spectrum of the pipeline.

[0040] It should be noted that the bottom plate 8 and the first connecting rod 9 in the present invention can be integrally formed, but in order to improve the vibration reduction effect of the support and hanger 100, the bottom plate 8 and the first connecting rod 9 are preferably set as a detachable structure. When installing the bottom plate 8 and the first connecting rod 9, the relative position of the first connecting rod 9 and the bottom plate 8 can be adjusted to control the horizontal line spectrum. Specifically, the bottom 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 bottom plate 8 by the fastening nut 6.

The fixed connection method can be set to mortise and tenon, riveting or fixed connection by fasteners. The fasteners can be set to screws or bolts.

[0042] The cross section of the housing 4 can be set to be circular or square, and the connecting plate 5 can be set to be a disc structure or a square disc. Preferably, in this embodiment, the cross section of the housing 4 is set to be circular, the connecting plate 5 is set to be circular, and the diameter of the connecting plate 5 is smaller than the diameter of the housing 4, and 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 is provided on the connecting plate 5, a threaded structure is provided 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.

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

[0046] In other embodiments of the present invention, a method for assembling a pipeline support and hanger 100 is provided, including assembling any of the above pipeline support and hanger 100 by the assembly method; the assembly method includes:

[0047] Step S110, detecting the maximum vibration frequency value of the pipeline to be tested. A sensor is used to directly detect the vibration frequency of the pipeline to be tested during operation, and its maximum vibration frequency value is determined so as to assemble a support bracket 100 suitable for the pipeline to weaken the vibration generated by the pipeline.

[0048] Step S120, calculate the mass of the required counterweight shell and the length of the first connecting rod 9 according to the maximum vibration frequency value. According to the specific vibration frequency of the pipeline to be tested, the parameters of the components in the vibration absorption module connected to the pipeline are assembled to make the support and hanger 100 have a better shock absorption effect. After research, it was found that adjusting the length of the first connecting rod 9 connected to the pipeline and the weight of the counterweight shell is conducive to controlling the lateral propagation of vibration. Therefore, the present invention obtains the relevant parameters of the first connecting rod 9 and the counterweight shell by determining the vibration frequency of the pipeline, and specifically generates a support and hanger 100 that is vibration-adaptive for different pipelines. Specifically, step S120 includes:

[0049] Step S121, according to 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 by the following calculation formula:

[0050] m=k / (2πf) 2 ;

[0051] Step S121, the length L of the first connecting rod 9 is calculated according to the stiffness k of the first connecting rod 9, the Young's modulus E of the first connecting rod 9 and the cross-sectional inertia moment I of the first connecting rod 9, and the calculation formula is:

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

[0053] Step S130, installing the support and hanger 100. Since the parameters of the first connecting rod 9 and the counterweight shell can affect the shock absorption effect of the support and hanger 100, the operator further found that adjusting the relative position of the first connecting rod 9 and the bottom plate 8 will also affect the lateral vibration frequency controlled by the vibration absorption module. Therefore, the present invention adjusts the installation position of the first connecting rod 9 and the bottom plate 8 by testing the vibration reduction ability of the vibration absorption module and the vibration isolation module, so as to configure the support and hanger 100 required for different pipelines. Specifically, step S130 includes:

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

[0055] Step 132, install the assembled vibration absorption module on the pipeline, install the acceleration sensor on the cover plate 2 of the counterweight shell, use the hammer method to test the vibration absorption frequency of the vibration absorption module, and adjust the relative position of the bottom plate 8 of the counterweight block and the first connecting rod 9 according to the value detected by the acceleration sensor, until the vertical value detected by the acceleration sensor reaches the target value of the lateral vibration absorption frequency, and the vibration absorption module is installed. The target value of the lateral vibration absorption frequency can be obtained based on the experience of the operator through multiple tests, or can be obtained through experimental tests 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 with the nut. Then install the elastic element 3 between the cover plate 2 and the connecting plate 5, and after positioning, fix the position of the connecting plate 5 with the tightening nut 6; finally, install the cover plate 2 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 method to test the overall vibration absorption frequency of the support bracket 100. According to the value detected by the acceleration sensor during the hammering process and the target value of the overall vibration absorption frequency of the support bracket 100, adjust the relative positions 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 bracket 100. The installation of the support bracket 100 is completed.

[0058] Those skilled in the art can understand that the present invention receives the vibration generated by the pipeline through the vibration absorption module, controls the transverse line spectrum generated by the vibration, and then weakens the vibration through the vibration isolation module, so that the vibration generated by the pipeline has little or no effect on the installation foundation of the support and hanger 100. The support and hanger 100 of the present invention introduces dynamic vibration absorption technology, integrates the mass of its subsystem with the pipeline support and hanger shell, and greatly increases the integration of the system while realizing transverse line spectrum control. It has the advantage of a small installation space and effectively solves the transverse line spectrum vibration problem existing in the existing pipeline vibration control field.
