In order to enable any technician in the field to implement and use the utility model, the following description is given. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the utility model can be implemented without using these specific details.

Therefore, the utility model is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the present application.

[0038] This embodiment is installed on the structural beam 4 on the civil floor 6, wherein the structural beam 4 is used as the core supporting element, has a large rigidity, can effectively resist the effects of various external forces, and reduce the vibration transmission of multi-caliber and large-caliber pipelines. Then a pipeline vibration isolation hanger structure based on the installation on the structural beam is proposed, see Figure 1-Figure 4 , including a support component 1, a primary vibration isolation component 2, and a secondary vibration isolation component 3; the upper part of the support component 1 is welded to the structural beam 4, and the longitudinal section structure formed by the support component 1 and the structural beam 4 is a frame-type, the bottom of the primary vibration isolation component 2 is welded to the bottom of the frame, and the secondary vibration isolation component 3 is fixedly arranged on the upper part of the primary vibration isolation component 2, wherein a pipeline 5 is arranged on the secondary vibration isolation component 3, and the transmission of vibration and noise during the operation of the pipeline 5 is controlled by the primary vibration isolation component 2 and the secondary vibration isolation component 3, that is, due to the effects of the primary vibration isolation component 2 and the secondary vibration isolation component 3, the structure of this embodiment has large rigidity, good stability, low natural frequency, and is not easy to resonate, and the structure of this embodiment is suitable for both newly built pipeline 5 systems and the transformation and upgrading of old pipeline 5 systems. According to the needs of specific scenarios, multiple shells of the first-level vibration isolation assembly 2 and the second-level vibration isolation assembly 3 in the support assembly 1 can be set, and one first-level vibration isolation assembly 2 corresponds to one second-level vibration isolation assembly 3. Preferably, multiple first-level vibration isolation assemblies 2 are arranged side by side on the support assembly 1 to allow multiple pipes 5 to pass through the hanger structure at the same time.

[0039] In the specific implementation process, see Figure 1-Figure 4The support assembly 1 includes two hangers 11 with a U-shaped longitudinal cross-section and two cross braces 12; the two hangers 11 are symmetrically welded to the two sides of the structural beam 4, and the lower ends of the two hangers 11 are vertically welded through a cross brace 12 respectively, so that the cross-section of the bottom of the hangers 11 and the cross brace 12 is frame-shaped; more specifically, the support assembly 1 also includes an anchoring steel plate 13, so that the hanger 11 is connected to the structural beam 4 through the anchoring steel plate 13, and the upper part of the hanger 11 is welded to the anchoring steel plate 13, wherein the anchoring steel plate 13 is connected to the structural beam 4 through bolts 14, and the upper part of the structural beam 4 is integrally connected to the civil floor 6. Preferably, the hanger 11 and the cross brace 12 are both channel steel structures, and the opening direction of the hanger 11 is away from the cross brace 12; the opening direction of the cross brace 12 is away from the primary vibration isolation component 2; wherein, the bottom of the primary vibration isolation component 2 is welded to the two horizontal sides of the hangers 11 at the same time, and there is a gap between the bottom and the inner side wall of the vertical side of the hanger 11.

[0040] In a specific embodiment, see Figure 1-Figure 4 The first-level vibration isolation assembly 2 includes a base plate 21 and a spring vibration isolator 22; the base plate 21 is fixed to the horizontal sides of the two hangers 11, and the spring vibration isolator 22 is fixed to the upper end surface of the base plate 21. More specifically, a waist-shaped mounting hole is provided on the base plate 21, so that a screw passes through the waist-shaped mounting hole to fix the spring vibration isolator 22 to the base plate 21, and the spring vibration isolator 22 is a height-adjustable spring vibration isolator 22, which is equipped with horizontal bolts to adaptively adjust the height of the spring vibration isolator 22 according to different environments, that is, when the pipeline 5 is installed at different heights on the hanger structure, the height adjustment bolts of the spring vibration isolator 22 can be adjusted to keep the equipment level.

[0041] In a specific embodiment, see Figure 1-Figure 4The secondary vibration isolation component 3 includes a bracket 31 and a vibration isolation seat 32; the upper and lower parts of the bracket 31 are respectively connected to the vibration isolation seat 32 and the spring vibration isolator 22 by screws. Preferably, the vibration isolation seat 32 is made of rubber. At this time, when the vibration isolation seat 32 is connected to the bracket 31, the natural frequency is 10±2Hz, the rubber Shore hardness is 45°, and the connecting screws at both ends are self-matched according to different pipe diameters. The bracket 31 is preferably a channel steel. At this time, the opening direction of the channel steel faces outward, so that the screws of the primary vibration isolation component 2 pass through the spring vibration isolator 22 and extend into the groove of the channel steel and are fixed by nuts. Similarly, other screws extend from the groove of the channel steel to connect the secondary vibration isolation component 3 and the bracket 31, that is, through the bracket 31 of the channel steel structure, it is convenient to connect the vibration isolation seat 32 at the top and the spring vibration isolator 22 at the bottom. Furthermore, the structural design of the bracket 31 can reduce the weight of the entire hanger structure to a certain extent, while saving materials and reducing costs; wherein, a through hole 33 for the pipeline 5 to pass through is opened on the vibration isolation seat 32, so that the pipeline 5 of the power equipment passes through the through hole 33, and there is a gap between the bottom plate 21, the spring isolator 22, the bracket 31, the vibration isolation seat 32 and the inner wall of the hanger 11.

[0042] To facilitate the installation of power equipment pipeline 5, see Figure 1-Figure 4 The vibration isolation seat 32 includes an upper body 321 and a lower body 322 connected to the upper body 321 by screws. The upper body 321 and the lower body 322 are connected to form a structure with the through hole 33 in the middle. The pipe 5 is placed on the lower body 322 and then the upper body 321 is installed. At this time, the lower body 322 and the upper body 321 jointly fix the pipe 5 in the through hole 33. When there is an error between the size of the through hole 33 and the size of the pipe 5 to be passed through, the gap between the upper body 321 and the lower body 322 can be adjusted. During installation, a flexible material can be filled in the gap to fix the pipe 5 between the upper body 321 and the lower body 322. In more detail, the upper body 321 and the lower body 322 have the same structure but opposite directions, that is, the lower body 322 is provided with a semicircular structure in the middle to support the pipe 5, and the upper part of the pipe 5 is clamped by the semicircular structure on the upper body 321, so that the upper body 321 and the lower body 322 work together to fix the pipe 5. During this process, the tightening degree of the connecting screws of the upper body 321 and the lower body 322 needs to be moderate to fix the pipe 5. If it is too tight, it will affect the vibration isolation efficiency.

[0043] In the specific implementation process, see Figure 1-Figure 3There is a gap between the upper end surface of the vibration isolation seat 32 and the lower end surface of the structural beam 4, that is, there is a gap between the upper body 321 and the lower end surface of the structural beam 4; further, the material of the vibration isolation seat 32 is rubber, which can reduce the vibration and noise of the pipeline 5 to a certain extent. At the same time, the rubber material needs to be resistant to oil, weak acid, alkali, and aging.
