Description
Technical Field
[0001] The utility model relates to the research field of power pipeline vibration reduction and low magnetic environment, and in particular to a low magnetic vibration reduction hanger device for a power pipeline. Background Art
[0002] The hangers for power pipelines in current power equipment piping systems are typically constructed primarily of metal materials such as steel. The operating conditions for equipment and instruments in near-zero magnetic fields (such as the precision equipment required for neural signal measurement and magnetoencephalography research) require enhanced requirements for the magnetic field environment and vibration control of the equipment foundation. However, due to the widespread use of ferromagnetic steel hangers and other facilities in traditional power piping systems, the magnetic field they produce interferes with the surrounding environment and cannot meet the low-magnetic environment requirements required for research on equipment and instruments in these near-zero magnetic fields. In addition to the magnetic interference issue, the hangers in power piping systems are made of conventional steel, which has a high density and rigidity. This causes the power piping to easily produce large vibration responses when subjected to fluid impact or equipment vibration. Furthermore, the damping performance of hangers made of conventional steel is poor, making them unable to effectively absorb and attenuate vibration energy. Utility Model Content
[0003] The purpose of the utility model is to provide a low-magnetic vibration-damping hanger device for a power pipeline, which has low magnetism and can effectively avoid the residual magnetic pollution of the hanger to the "zero magnetic" space; and can reduce the vibration influence of the power pipeline on the "zero magnetic" space.
[0004] The technical solution of the utility model is:
[0005] A low-magnetic vibration-damping hanger device for a power pipeline, comprising:
[0006] The low-magnetic hanger structure includes a crossbar and a hanger. The crossbar is suspended below the building structure through the hanger. The hanger includes an upper hanger and a lower hanger. The upper end of the upper hanger is connected to the building structure, and the crossbar is connected to the lower end of the lower hanger. Both the crossbar and the lower hanger are made of low-magnetic steel. The power pipeline is supported on the crossbar.
[0007] A low-magnetic vibration damping structure includes a vibration damping spring and a frame connected to the lower end of an upper hanger. A positioning plate is provided at the upper end of the lower hanger. The positioning plate is supported on the frame by a vibration damping spring. The frame, positioning plate and vibration damping spring are all made of low-magnetic steel. In this scheme, a low-magnetic vibration damping hanger device for a power pipeline is made of low-magnetic steel, on the one hand, the crossbar of the main structure and the lower hanger, as well as the frame, positioning plate and vibration damping spring of the low-magnetic vibration damping structure are all made of low-magnetic steel. Low-magnetic steel is steel that is non-inductive to ferromagnetism and has the characteristics of stable structure, excellent mechanical properties, low magnetic permeability and high resistivity. Therefore, it can meet the requirements of residual magnetism and avoid the residual magnetism pollution of the hanger to the "zero magnetic" space. On the other hand, a low-magnetic vibration damping structure is used to connect the upper hanger and the lower hanger. There is a certain distance between the upper hanger and the lower hanger so that the two parts are not in direct contact. The elastic deformation of the vibration damping spring can be used to consume vibration energy, effectively reducing the vibration transmitted to the building structure and reducing the transmission of external vibration to precision equipment, thereby playing the role of vibration isolation and vibration reduction. In addition, the low-magnetic vibration damping hanger device for power pipelines uses cross bars and hangers as the main structure, which can provide stable support for the power pipelines; a positioning plate is also provided on the vibration damping springs to fix and position the vibration damping springs in the hanger to ensure that they can remain stable when subjected to vibration.
[0008] Preferably, the low-magnetic vibration reduction structure also includes vibration-reducing rubber. The bottom of the upper suspension rod is provided with a support plate and an upper nut connected by a thread. The frame includes a top frame. The support plate is located below the top frame. The upper nut is located below the support plate. The vibration-reducing rubber is pressed between the support plate and the top frame to connect the frame to the lower end of the upper suspension rod. The low-magnetic vibration reduction structure of this solution uses vibration-reducing rubber to isolate the top frame and the support plate of the frame, so that the upper suspension rod and the frame are not in direct contact, but are connected through the vibration-reducing rubber. In this way, the elastic deformation of the vibration-reducing rubber can cooperate with the vibration-reducing spring to further consume vibration energy, effectively reduce the vibration transmitted to the building structure, and reduce the transmission of external vibration to precision equipment, thereby playing a role in vibration isolation and vibration reduction.
[0009] Preferably, the support plate and upper nut are both made of low-magnetic steel. Using low-magnetic steel to make the support plate and upper nut allows the use of low-magnetic steel's characteristics of structural stability, excellent mechanical properties, low magnetic permeability, and high resistivity to further meet residual magnetism requirements and avoid residual magnetism contamination of the "zero-magnetic" space by the hanger assembly.
[0010] Preferably, a threaded lower nut is provided at the top of the lower suspension rod, a suspension rod through-hole is provided in the middle of the positioning plate, the upper end of the lower suspension rod passes through the suspension rod through-hole, and the lower nut is located above the positioning plate. The positioning plate can move up and down along the lower suspension rod, and the positioning plate rests on the lower nut under the action of the vibration-damping spring. In this way, on the one hand, the lower nut can be used to restrain the positioning plates, ensuring that they remain stable when subjected to vibration; on the other hand, the lower nut can be used to adjust the initial compression of the vibration-damping spring, thereby adjusting the vibration-damping spring's absorption of vibrations of different frequencies to adapt to the requirements of different vibration frequency scenarios and environments.
[0011] Preferably, the lower nut is made of low-magnetic steel. This allows the use of low-magnetic steel, which has stable structure, excellent mechanical properties, low magnetic permeability, and high resistivity, to further meet residual magnetism requirements and avoid residual magnetism contamination of the "zero magnetism" space by the hanger assembly.
[0012] Preferably, the low-magnetic vibration damping structure further includes a rubber pad. The frame includes a base frame, the upper end of the lower suspension rod passes through the base frame and is located above the base frame, the positioning plate is located above the base frame, the vibration damping spring is located between the positioning plate and the base frame, and the rubber pad is located between the vibration damping spring and the base frame. Thus, on the one hand, by positioning the positioning plate above the base frame and the vibration damping spring between the positioning plate and the base frame, the vibration damping spring in the suspension frame is fixed and positioned, ensuring that it remains stable when subjected to vibration. On the other hand, by arranging the rubber pad between the vibration damping spring and the base frame, the rubber pad can further dissipate vibration energy, reducing the vibration transmitted to the equipment foundation and reducing the transmission of external vibration to the precision equipment.
[0013] Preferably, the upper suspension rod is made of low-magnetic steel. This allows the use of low-magnetic steel's characteristics of structural stability, excellent mechanical properties, low magnetic permeability, and high resistivity to further meet residual magnetism requirements and avoid residual magnetism contamination of the "zero magnetism" space by the hanger device.
[0014] Preferably, the crossbar is provided with a through-hole, and a threaded support nut is provided at the bottom of the lower suspension rod. The lower end of the lower suspension rod passes through the through-hole, and the support nut is located below the crossbar, and the crossbar is supported on the support nut. This ensures the stability of the crossbar, provides stable support for the power pipeline, and facilitates the installation and removal of the crossbar.
[0015] Preferably, the support nut is made of low-magnetic steel. Using low-magnetic steel to make the support nut can take advantage of the steel's stable structure, excellent mechanical properties, low magnetic permeability, and high resistivity, further meeting residual magnetism requirements and avoiding residual magnetism contamination of the "zero-magnetic" space by the hanger assembly.
[0016] Preferably, the crossbar is suspended below the building structure via two hangers, with the aforementioned low-magnetic vibration damping structure installed between the upper and lower hangers of each hanger. This ensures the stability of the crossbar and hanger structure, which form the main structure of the low-magnetic vibration damping hanger device for the power pipeline, ensuring they remain stable when subjected to vibration, thereby providing stable support for the power pipeline. Furthermore, the low-magnetic vibration damping structure dissipates vibration energy, effectively reducing vibration transmitted to the building structure and reducing the transmission of external vibration to precision equipment, thereby providing vibration isolation.
[0017] The beneficial effects of the utility model are: it has low magnetism, which can effectively avoid the residual magnetism pollution of the hanger to the "zero magnet" space; it also has vibration isolation and vibration reduction effects, which can effectively reduce the vibration impact of the power pipeline on the "zero magnet" space.

[0026] Specific embodiment 1, as Figure 1 、 Figure 2As shown, a low-magnetic vibration damping hanger device for a power pipeline includes a low-magnetic hanger structure and a low-magnetic vibration damping structure 3. The low-magnetic hanger structure includes a crossbar 1 and a hanger 2. The crossbar 1 is suspended below a building structure 4 through the hanger 2. The building structure 4 generally refers to a concrete building, such as a concrete floor slab, a concrete beam, etc. The hanger 2 includes an upper hanger 2.1 and a lower hanger 2.2. The crossbar 1 is connected to the lower end of the lower hanger 2.2. The upper end of the upper hanger 2.1 is connected to the building structure 4. The low-magnetic vibration damping structure 3 is arranged between the upper hanger 2.1 and the lower hanger 2.2. The upper hanger 2.1 and the lower hanger 2.2 of the hanger 2 are connected through the low-magnetic vibration damping structure 3. The low-magnetic vibration damping structure 3 includes a vibration damping spring 3.2 and a frame 3.1. The frame 3.1 is connected to the lower end of the upper hanger 2.1. A positioning plate 3.3 is provided at the upper end of the lower hanger 2.2. Positioning plate 3.3 is supported on frame 3.1 via damping springs 3.2. This, in turn, supports lower boom 2.2 and crossbar 1 on frame 3.1 via positioning plate 3.3 and damping springs 3.2. Crossbar 1 and lower boom 2.2 are both made of low-magnetic steel. Frame 3.1, positioning plate 3.3, and damping springs 3.2 are also made of low-magnetic steel. The power pipeline is supported on crossbar 1.
[0027] The present embodiment is a low-magnetic vibration-damping hanger device for a power pipeline. On the one hand, the cross bar 1 and the lower hanger 2.2 of the main structure and the frame 3.1, the positioning plate 3.3 and the vibration-damping spring 3.2 of the low-magnetic vibration-damping structure 3 are all made of low-magnetic steel. Low-magnetic steel is steel that is insensitive to ferromagnetism and has the characteristics of stable structure, excellent mechanical properties, low magnetic permeability and high resistivity. Therefore, it can meet the requirements of residual magnetism and avoid the residual magnetism pollution of the "zero magnetism" space by the hanger; on the other hand, the low-magnetic vibration-damping structure 3 is used to connect the upper hanger 2.1 and the lower hanger 2.2. There is a certain distance between the upper hanger 2.1 and the lower hanger 2.2 so that the two parts are not in direct contact. The elastic deformation of the vibration-damping spring 3.2 can consume vibration energy, effectively reduce the vibration transmitted to the building structure, reduce the transmission of external vibration to precision equipment, play the role of vibration isolation and vibration reduction, and can effectively reduce the impact of the power pipeline on the vibration environment. In addition, the low-magnetic vibration-damping hanger device for the power pipeline uses a crossbar 1 and a hanger 2 as the main structure, which can provide stable support for the power pipeline; a positioning plate 3.3 is also provided on the vibration-damping spring 3.2 to fix and position the vibration-damping spring 3.2 in the hanger to ensure that they can remain stable when subjected to vibration.
[0028] Specific embodiment 2, as Figure 1 、 Figure 2 As shown, a low-magnetic vibration reduction hanger device for a power pipeline includes a low-magnetic hanger structure and a low-magnetic vibration reduction structure 3.
[0029] The low-magnetic hanger structure includes a crossbar 1 and a hanger 2. Crossbar 1 is suspended from a building structure 4 by hanger 2. Building structure 4 is typically a concrete structure, such as a concrete floor slab or concrete beam. Hanger 2 includes an upper hanger 2.1 and a lower hanger 2.2. Crossbar 1 is connected to the lower end of lower hanger 2.2.
[0030] The upper end of the upper suspension rod 2.1 is connected to the building structure 4. The upper end of the upper suspension rod 2.1 is directly or indirectly connected to the building structure 4. Specifically:
[0031] In one example, the upper end of the upper suspension rod 2.1 is indirectly connected to the building structure 4. For example, an expansion anchor bolt is provided in the building structure 4, and the upper end of the upper suspension rod 2.1 is connected to the expansion anchor bolt by bolts, welding, or riveting. The upper suspension rod 2.1 is connected to the building structure 4 via the expansion anchor bolt, thereby achieving an indirect connection between the upper end of the upper suspension rod 2.1 and the building structure 4.
[0032] In another example, the upper end of the upper suspension rod 2.1 is directly connected to the building structure 4. For example, the upper portion of the upper suspension rod 2.1 includes expansion anchor bolts, and the upper suspension rod 2.1 is directly fixedly connected to the building structure 4 through the expansion anchor bolts.
[0033] The low-magnetic vibration damping structure 3 is arranged between the upper suspension rod 2.1 and the lower suspension rod 2.2. The upper suspension rod 2.1 and the lower suspension rod 2.2 of the suspension rod 2 are connected by the low-magnetic vibration damping structure 3. The low-magnetic vibration damping structure 3 includes a vibration damping spring 3.2 and a frame 3.1. The frame 3.1 is connected to the lower end of the upper suspension rod 2.1. A positioning plate 3.3 is provided at the upper end of the lower suspension rod 2.2. The positioning plate 3.3 is supported on the frame 3.1 by the vibration damping spring 3.2, so that the lower suspension rod 2.2 and the crossbar 1 are supported on the frame 3.1 by the positioning plate 3.3 and the vibration damping spring 3.2. The crossbar 1 and the lower suspension rod 2.2 are both made of low-magnetic steel. The frame 3.1, the positioning plate 3.3 and the vibration damping spring 3.2 are all made of low-magnetic steel. The power pipeline is supported on the crossbar 1.
[0034] The present embodiment is a low-magnetic vibration-damping hanger device for a power pipeline. On the one hand, the cross bar 1 and the lower hanger 2.2 of the main structure and the frame 3.1, the positioning plate 3.3 and the vibration-damping spring 3.2 of the low-magnetic vibration-damping structure 3 are all made of low-magnetic steel. Low-magnetic steel is steel that is insensitive to ferromagnetism and has the characteristics of stable structure, excellent mechanical properties, low magnetic permeability and high resistivity. Therefore, it can meet the requirements of residual magnetism and avoid the residual magnetism pollution of the "zero magnetism" space by the hanger; on the other hand, the low-magnetic vibration-damping structure 3 is used to connect the upper hanger 2.1 and the lower hanger 2.2. There is a certain distance between the upper hanger 2.1 and the lower hanger 2.2 so that the two parts are not in direct contact. The elastic deformation of the vibration-damping spring 3.2 can consume vibration energy, effectively reduce the vibration transmitted to the building structure, reduce the transmission of external vibration to precision equipment, play the role of vibration isolation and vibration reduction, and can effectively reduce the impact of the power pipeline on the vibration environment. In addition, the low-magnetic vibration-damping hanger device for the power pipeline uses a crossbar 1 and a hanger 2 as the main structure, which can provide stable support for the power pipeline; a positioning plate 3.3 is also provided on the vibration-damping spring 3.2 to fix and position the vibration-damping spring 3.2 in the hanger to ensure that they can remain stable when subjected to vibration.
[0035] Specifically, such as Figure 1 As shown, a crossbar 1 is suspended below a building structure 4 via two hangers 2. Each hanger 2 has a low-magnetic vibration damping structure 3 installed between the upper hanger 2.1 and the lower hanger 2.2. This ensures the structural stability of the crossbar 1 and hangers 2, which form the main structure of the low-magnetic vibration damping hanger device for power pipelines, ensuring they remain stable when subjected to vibration, thereby providing stable support for the power pipelines. Furthermore, the low-magnetic vibration damping structure 3 dissipates vibration energy, effectively reducing vibration transmitted to the building structure and reducing the transmission of external vibration to precision equipment, thereby providing vibration isolation.
[0036] Furthermore, the upper suspension rod 2.1 is made of low-magnetic steel. This allows the use of low-magnetic steel's characteristics of stable structure, excellent mechanical properties, low magnetic permeability, and high resistivity to further meet residual magnetism requirements and avoid residual magnetism contamination of the "zero magnetism" space by the hanger device.
[0037] Further, such as Figure 1 、 Figure 2As shown, the low-magnetic vibration reduction structure 3 also includes a vibration-damping rubber 3.5. A support plate 3.6 and an upper nut 3.7 threadedly connected are provided at the bottom of the upper suspension rod 2.1. The frame 3.1 includes a top frame 3.1.1. The support plate 3.6 is located below the top frame 3.1.1. The upper nut 3.7 is located below the support plate 3.6. The vibration-damping rubber 3.5 is located between the support plate 3.6 and the top frame 3.1.1. The vibration-damping rubber 3.5 is pressed between the support plate 3.6 and the top frame 3.1.1; specifically, by locking the upper nut 3.7, the vibration-damping rubber 3.5 is pressed between the support plate 3.6 and the top frame 3.1.1, so that the frame 3.1 is connected to the lower end of the upper suspension rod 2.1. The low-magnetic vibration-damping structure 3 of this solution uses vibration-damping rubber 3.5 to isolate the top frame 3.1.1 of the frame 3.1 from the support plate 3.6. This ensures that the upper suspension rod 2.1 and the frame 3.1 are not in direct contact, but are connected through the vibration-damping rubber 3.5. This allows the elastic deformation of the vibration-damping rubber 3.5 to cooperate with the vibration-damping spring 3.2, further consuming vibration energy, effectively reducing the vibration transmitted to the building structure and the transmission of external vibration to precision equipment, thereby achieving the effect of vibration isolation and vibration reduction. Furthermore, by tightening the upper nut 3.7, the vibration-damping rubber 3.5 is compressed between the support plate 3.6 and the top frame 3.1.1, thereby connecting the frame 3.1 to the lower end of the upper suspension rod 2.1. This also ensures the stability of the connection between the upper suspension rod 2.1 and the frame 3.1, providing stable support for the power pipeline.
[0038] In one example, a stopper hole is provided in the center of the top frame 3.1.1 of the frame 3.1. A stopper post extending upward is provided on the top of the vibration-damping rubber 3.5. The stopper post extends into the stopper hole and forms an interference fit with the stopper hole. A through hole extending vertically is provided in the center of the vibration-damping rubber 3.5. The through hole extends through the top and bottom of the vibration-damping rubber 3.5 and through the stopper post. The upper suspension rod 2.1 passes through the through hole.
[0039] Both the support plate 3.6 and the upper nut 3.7 are made of low-magnetic steel. This allows the use of low-magnetic steel's characteristics of structural stability, excellent mechanical properties, low magnetic permeability, and high resistivity to further meet residual magnetism requirements and avoid residual magnetism contamination of the "zero-magnetic" space by the hanger assembly.
[0040] Further, such as Figure 2As shown, a threaded lower nut 3.4 is provided at the top of the lower suspension rod 2.2. A through hole for suspension rod 2 is provided in the middle of the positioning plate 3.3. The upper end of the lower suspension rod 2.2 passes through the through hole for suspension rod 2. The lower nut 3.4 is located above the positioning plate 3.3. The positioning plate 3.3 can move up and down along the lower suspension rod 2.2, and the positioning plate 3.3 rests on the lower nut 3.4 under the action of the shock-absorbing spring 3.2. In this way, on the one hand, the positioning plate 3.3 can be restricted by the lower nut 3.4 to ensure that they can remain stable when subjected to vibration; on the other hand, the lower nut 3.4 is used to adjust the initial compression amount of the shock-absorbing spring 3.2, and then adjust the consumption of the shock-absorbing spring 3.2 to vibrations of different frequencies to adapt to the adaptation requirements of different vibration frequency scene environments.
[0041] In this embodiment, the edge of the positioning plate 3.3 is provided with an annular upper limit flange extending downward. The upper end of the damping spring 3.2 is located within the annular upper limit flange, and the upper end of the damping spring 3.2 is limited by the annular upper limit flange.
[0042] The lower nut 3.4 is made of low-magnetic steel. This allows the use of low-magnetic steel's characteristics of stable structure, excellent mechanical properties, low magnetic permeability, and high resistivity to further meet residual magnetism requirements and avoid residual magnetism contamination of the "zero magnetism" space by the hanger device.
[0043] Further, such as Figure 2 As shown, the low-magnetic vibration damping structure 3 also includes a rubber pad 3.8. The frame 3.1 also includes a base frame 3.1.2. The upper end of the lower suspension rod 2.2 passes through the base frame 3.1.2 and is located above the base frame 3.1.2. The positioning plate 3.3 is located above the base frame 3.1.2, the vibration damping spring 3.2 is located between the positioning plate 3.3 and the base frame 3.1.2, and the rubber pad 3.8 is located between the vibration damping spring 3.2 and the base frame 3.1.2. In this way, on the one hand, by positioning the positioning plate 3.3 above the base frame 3.1.2 and the vibration damping spring 3.2 between the positioning plate 3.3 and the base frame 3.1.2, the vibration damping spring 3.2 in the hanger is fixed and positioned to ensure that they can remain stable when subjected to vibration; on the other hand, by arranging the rubber pad 3.8 between the vibration damping spring 3.2 and the base frame 3.1.2, the rubber pad 3.8 can also be used to further consume vibration energy, reduce the vibration transmitted to the equipment foundation, and reduce the transmission of external vibration to precision equipment.
[0044] In this embodiment, the frame 3.1 further includes a side bracket 3.1.3 connecting the top frame 3.1.1 and the bottom frame 3.1.2, that is, the frame 3.1 includes the top frame 3.1.1, the bottom frame 3.1.2, and the side bracket 3.1.3 connecting the top frame 3.1.1 and the bottom frame 3.1.2. The positioning plate 3.3 is located between the top frame 3.1.1 and the bottom frame 3.1.2.
[0045] The rubber pad 3.8 has a central opening through which the upper end of the lower suspension rod 2.2 passes. The edge of the rubber pad 3.8 is provided with a downwardly extending annular lower stop flange. The lower end of the damping spring 3.2 is positioned within the annular lower stop flange, which holds the damping spring 3.2 in place.
[0046] Further, such as Figure 1 As shown, crossbar 1 is provided with a crossbar through-hole. A threaded support nut 5 is provided at the bottom of lower suspension rod 2.2. The lower end of lower suspension rod 2.2 passes through the crossbar through-hole. Support nut 5 is located below crossbar 1, and crossbar 1 rests on support nut 5. This ensures the stability of crossbar 1, providing stable support for the power pipeline, while also facilitating installation and removal of crossbar 1.
[0047] The support nut 5 is made of low-magnetic steel. Using low-magnetic steel to make the support nut 5 can take advantage of the characteristics of low-magnetic steel, such as stable structure, excellent mechanical properties, low magnetic permeability and high resistivity, to further meet the residual magnetism requirements and avoid residual magnetism contamination of the "zero magnetism" space by the hanger device.
[0048] Of course, it should be noted that the lower end of the lower suspension rod 2.2 and the cross bar 1 can also be connected by welding or riveting.
[0049] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any way. Any simple modification, change and equivalent transformation of the above embodiment based on the technical essence of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
