Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all embodiments. All other implementation manners obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present invention belong to the scope protected by the present invention.

[0036] Embodiment 1:

[0037] This embodiment provides a vibration-absorbing elastic support hanger, which is used to solve the technical problem that the elastic support hanger for installing pipelines on a ship in the prior art has a poor vibration reduction effect on the vibration transmitted from the pipeline to the base. Specifically, the elastic support hanger in the prior art can significantly reduce the broadband vibration transmitted from the pipeline to the base, but for the vibration of the low-frequency line spectrum, the vibration isolation effect of the existing elastic support hanger is poor.

[0038] The vibration-absorbing elastic support hanger includes a support leg 3, a plate body 1, a vibration isolator 2, a vibration absorber 4, and a clamping component. The plate body 1 is a flat plate. The support leg 3 is used to connect to the base on the ship. Specifically, an angle steel 32 is provided on the support leg 3, and the angle steel 32 is welded or connected to the base by screws. The above-mentioned plate body 1 is installed on the support leg 3 through the vibration isolator 2. As a specific implementation manner of this embodiment, the support leg 3 in this embodiment includes a support plate 31. The above-mentioned angle steel 32 is welded and fixedly installed on the support plate 31 to form the support leg 3. The plate body 1 is located above the support plate 31, and mounting holes are provided on the opposite side walls of the plate body 1 and the support plate 31. The two ends of the vibration isolator 2 are respectively installed in the mounting holes on the plate body 1 and the mounting holes on the support plate 31. In this way, the vibration isolator 2 can block and buffer the high-frequency line spectrum vibration transmitted from the plate body 1 to the support plate 31. A clamping component is installed on the plate body 1, and the clamping component is used to clamp the pipeline on the plate body 1. In this way, the high-frequency line spectrum vibration transmitted from the pipeline to the plate body 1 can be blocked by the vibration isolator 2. The above-mentioned vibration absorber 4 is installed on the plate body 1, so as to absorb the low-frequency line spectrum vibration of the plate body 1. Of course, other block structures can also be used to replace the above-mentioned angle steel 32

[0039] With the above structure, the vibration-absorbing elastic support hanger provided in this embodiment integrates the vibration absorber 4 and the vibration isolator 2. The vibration absorber 4 absorbs the low-frequency line spectrum vibration transmitted from the pipeline, and the vibration isolator 2 blocks the high-frequency line spectrum vibration transmitted from the pipeline, so as to better buffer the vibration generated by the pipeline and reduce the influence of the pipeline vibration on the base and the ship. The vibration-absorbing elastic support hanger also has the advantages of simple structure, convenient disassembly and assembly, and convenient debugging.

[0040] The number of vibration absorbers 4 in this embodiment is multiple, such as 2, 4, etc. Multiple vibration absorbers 4 are evenly distributed around and clamped to better absorb the vibration of the low-frequency line spectrum. Moreover, the number of the above-mentioned vibration isolators 2 is also multiple, and multiple vibration isolators 2 are evenly distributed between the plate body 1 and the support plate 31 to achieve a better effect of isolating high-frequency line spectrum vibration.

[0041] It should be noted that the installation methods of the vibration absorber 4 and the vibration isolator 2 in this embodiment are the same as those in the prior art, so no detailed description will be given here. In addition, the vibration isolator 2 in this embodiment is internally provided with a spring, so that the vibration-absorbing elastic support hanger has a certain elasticity.

[0042] As an implementation manner of this embodiment, the clamping component in this embodiment includes a pressing plate 5 and a locking member. The pressing plate 5 is detachably and fixedly installed on the plate body 1 through the locking member. When it is necessary to clamp the pipeline, the locking member is used to lock the pressing plate 5 on the plate body 1. The pressing plate 5 can clamp the pipeline on the plate body 1. When it is not necessary to clamp the pipeline, the locking member is simply opened. The locking member in this embodiment can be a steel wire, and the steel wire binds the pressing plate 5 to the plate body 1. As an optimal implementation manner of this embodiment, the locking member in this embodiment includes a stud 6 and a nut 7. Studs 6 are provided at both ends of the pressing plate 5, and the pressing plate 5 and the studs 6 at both ends of the pressing plate 5 form a U-shaped structure. At least two through holes are provided on the plate body 1, and one stud 6 is inserted into each through hole. At least two nuts 7 are screwed onto each stud 6. The at least two nuts 7 on the same stud 6 include a first nut and a second nut, and the first nut and the second nut are respectively distributed on both sides of the plate body 1. Optimally, in this embodiment, a stud 6 is provided at each end of the pressing plate 5, two nuts 7 are screwed onto each stud 6, the number of through holes on the plate body 1 is two, one stud 6 is inserted into each through hole, and two nuts 7 are screwed onto each stud 6. Of course, two or three or more studs 6 can also be provided at each end of the pressing plate 5, and three or four or more nuts 7 can also be screwed onto each stud 6.

[0043] During installation, first screw one nut 7 onto the stud 6, then insert the stud 6 into the through hole on the plate body 1, and then screw the other nut 7 into the lower part of the plate body 1, and use the pre-tightening force of the two nuts 7 for locking. This locking structure is convenient for adjustment and can adjust the distance between the pressing plate 5 and the plate body 1 as needed, and is simple and convenient to use.

[0044] As an optimal implementation manner of this embodiment, the pressing plate 5 in this embodiment is an arc-shaped plate, and the center of the arc of the pressing plate 5 is located on the side close to the plate body 1. The radian and radius of curvature of the arc-shaped plate are adapted to the pipeline to be clamped. Specifically, multiple models of pressing plates 5 can be designed and manufactured. When installing the pipeline, a matching model of pressing plate 5 can be selected.

[0045] As a more optimal implementation manner of this embodiment, a rubber sleeve 8 is sleeved outside the pressing plate 5 in this embodiment, so as to prevent the pipeline from directly contacting the pressing plate 5 and causing damage, and the rubber sleeve 8 can also absorb part of the vibration of the pipeline and improve the vibration absorption effect. As another implementation manner of this embodiment, in this embodiment, a rubber plate can also be pasted only on the side plate surface of the pressing plate 5 close to the plate body 1. As another implementation manner of this embodiment, in this embodiment, rubber skin can also be wound around the position of the pipeline opposite to the pressing plate.

[0046] As a more preferred implementation of this embodiment, in this embodiment, a backing plate 9 is further installed at a position on the plate body 1 opposite to the pressing plate 5. One side plate surface of the backing plate 9 that is in contact with the plate body 1 is a flat surface, and this flat surface is adhered to the plate body 1. Of course, the backing plate 9 can also be installed on the plate body 1 by screws. In this way, when the pipeline is fastened, the pipeline does not directly contact the plate body 1 but contacts the backing plate 9, thereby further protecting the pipeline. Optimally, the backing plate 9 in this embodiment is also a structural member made of rubber, and an arc-shaped groove 91 adapted to the pipeline is recessed on one side plate surface of the backing plate 9 close to the pressing plate 5. During use, the pipeline is laid in the arc-shaped groove 91 to better position the pipeline. Of course, during design and manufacturing, centering-type backing plates 9 can be manufactured to correspond to pipelines of different model specifications. In addition, in this embodiment, an arc-shaped groove 91 can also be opened on one side plate surface of the backing plate 9 close to the pressing plate 5, that is, one side plate surface of the backing plate 9 close to the pressing plate 5 is a flat surface.

[0047] As another implementation of this embodiment, the shock absorber 4 in this embodiment can also be arranged inside the vibration isolator 2.

[0048] Embodiment 2:

[0049] As a more preferred implementation of Embodiment 1, in this embodiment, a plurality of cavities are provided in the above-mentioned backing plate 9, and wooden blocks 10 are filled in the cavities. Optimally, the cavities are spherical in shape, and the wooden blocks 10 are also spherical beads. During actual production, the above-mentioned wooden blocks 10 are encapsulated inside the backing plate 9. In this way, the backing plate 9 can absorb a wider range of vibration frequencies and the structural strength of the backing plate 9 can be increased.

[0050] During specific manufacturing, a large number of spherical wooden blocks 10 can be added to the raw materials for casting the backing plate 9, and the wooden blocks 10 will be encapsulated in the backing plate 9 during casting.
