Description
Technical field
The present invention relates to a kind of ship pipeline Control Technique of Vibration and Noise, and in particular to one kind can be used for ship pipeline vibration
The pipeline of isolation flexibly supports.
Background technique
It is taken seriously increasingly in view of marine environmental protection, Ship Vibration noise control obtains extensive concern.In mechanical equipment
It after the vibration transmitted along under-chassis is effectively isolated, is gradually highlighted by the vibration that pipeline transmits, corresponding control need to be taken to arrange
It applies.Currently, in pipeline vibration noise control, the main method combined using setting pipeline flexibility connection pipe with resilient support,
To be effectively isolated the transmitting of system pipeline vibration, wherein installation high-performance pipeline resilient support is reduce pipeline vibration transmitting one
Kind effective measures.
The characteristics of for ship pipeline system and Noise and Vibration Control demand, the successful pipeline resilient support of a design
The ability that need to be provided simultaneously with are as follows: first is that especially middle low-frequency range has good vibration isolation effect in wider frequency range,
Therefore the damping elastomer component of pipeline resilient support should have Low rigidity characteristic；Two be that pipeline resilient support should have height adjustment function
Can, it can compensate for the height tolerance that the installation mode such as pipeline filling liquid, pump pressure generates, avoid producing pipeline flexibility connection pipe because of height tolerance
Raw biggish additional damage power；Third is that pipeline resilient support should have the restraining ability for avoiding pipeline from generating large deformation, to ensure
When ship's navigation waves and encounters external impact, pipeline Deformation control is in safe range；Finally, numerous in view of ship equipment,
The factors such as cabin space is narrow, pipeline arrangement is close, pipeline resilient support should be designed to it is compact-sized, easy for installation, convenient for pipe
The arrangement of road neat appearance.
In recent years, dealer proposes multiple technologies solution to pipeline resilient support.Chinese patent
201721155680.X proposes a kind of wide range adjustable height pipe-support device, which includes upper and lower backing plate, pipeline
Branch hangs mounting assembly and screw rod regulating mechanism；It includes clip rubber layer, clip, cushion block, bolt, nut that pipeline branch, which hangs mounting assembly,
And gasket, clip and clip layer, liner vulcanization are integrated, liner is axial to be uniformly distributed groove；Pipeline branch is hung mounting assembly and is fixed
It is mounted on above upper padding plate, and fixed pipeline；Lower bolster is fixedly connected by bolt and nut with pedestal, screw rod regulating mechanism connection
Between upper and lower backing plate, the distance between upper and lower backing plate is changed by the screw rod of positive and negative rotation screw rod regulating mechanism, realizes pipe
Road support device height freely adjusts；Rubber packing and cushion block are compressed pipeline by bolt clip and upper padding plate by the device,
Rubber packing is larger with stow-wood stiffness, and vibration isolation effect is poor；Due to rubber creep properties, rubber packing and cushion block are to pipeline
Pressing force will be gradually reduced at any time, be not easy to be reliably fixed pipeline.
Chinese patent 201620907406.2 proposes a kind of adjustable pipeline elasticity branch with limit function and hangs, the branch
The pipeline fixation kit hung is identical as Chinese patent 201721155680.X, and height adjustment is real by bidirectional helical sleeve assembly
It is existing, it is provided with an elastic spacing component under bidirectional helical sleeve assembly, makes up the deficiency of pipeline flexible fastening component vibration isolating effect.
Chinese patent 201420399482.8 discloses a kind of adjustable elastic pipe clamp, which will by two " Ω " shape clips
On pipeline, height adjustment uses the bidirectional helical sleeve similar with Chinese patent 201620907406.2 for rubber elastic layer outsourcing
Component realizes that bidirectional helical sleeve assembly one end is connect with " Ω " shape flexible collar, one damper connection of the other end.The two
The height adjustment technical solution that patent is mentioned realizes that the pipeline lateral stiffness after installation is poor by bidirectional helical sleeve assembly,
And equally exist the deficiency that pipeline pressing force will be gradually reduced at any time due to caused by rubber creep.
Chinese patent application 201310583295.5 discloses a kind of resilient supporting unit for vibration isolation of pipeline, the device
By the fixed pipeline of " Ω " shape clip of two inside laying vibration insulations, and lower catch hoop vulcanization is embedded in an elastic rubber member
In, have vibration isolating effect good, advantages of simple structure and simple, but it is directed to the pipeline of different size, it need to open up and accordingly touch tool vulcanization production,
And dismounting need to be repeated several times in pipeline installation and debugging without oneself height regulatory function in the device.
