The invention relates to a technology for controlling vibration noise of a ship pipeline system, in particular to an elastic support for vibration isolation of a ship pipeline.
Background
In view of the increasing importance of marine environmental protection, the control of ship vibration noise is widely focused. After the vibration transmitted by the mechanical equipment along the machine leg is effectively isolated, the vibration transmitted by the pipeline is gradually highlighted, and corresponding control measures are required. At present, in pipeline vibration noise control, a method of combining a pipeline flexible connecting pipe with an elastic support is mainly adopted to effectively isolate transmission of system pipeline vibration, wherein the installation of a high-performance pipeline elastic support is an effective measure for reducing transmission of pipeline vibration.
Aiming at the characteristics of a ship pipeline system and the vibration noise control requirement, the pipeline elastic support with successful design has the following capability: firstly, the vibration isolation effect is good in a wider frequency range, particularly in a middle-low frequency range, so that the vibration isolation elastic component of the pipeline elastic support has low rigidity; the elastic support of the pipeline has a height adjusting function, can compensate the height deviation generated by installation adjustment of liquid filling, pumping pressure and the like of the pipeline, and avoids larger additional destructive force on the flexible connecting pipe of the pipeline due to the height deviation; thirdly, the elastic support of the pipeline has limit capability of avoiding large deformation of the pipeline so as to ensure that the deformation of the pipeline is controlled within a safe range when the ship sails and swings and encounters external impact; finally, in view of the factors of numerous ship devices, narrow cabin space, tight pipeline arrangement and the like, the pipeline elastic support is designed to be compact in structure, convenient to install and convenient for tidily and attractive arrangement of pipelines, and particularly, for numerous small-caliber pipelines, the elastic support of a plurality of pipelines by using one integral structure is a good solution.
In recent years, industry has proposed various technical solutions to the elastic support of pipes. Chinese patent 201721155680.X proposes a wide range height adjustable pipeline supporting device, which comprises upper and lower pad plates, a pipeline supporting and hanging installation assembly and a screw adjusting mechanism; the pipeline supporting and hanging installation assembly comprises a clamp rubber layer, a clamp, a cushion block, bolts, nuts and gaskets, wherein the clamp and the clamp layer are vulcanized into a whole, and grooves are uniformly distributed in the axial direction of the gasket; the pipeline supporting and hanging installation assembly is fixedly installed above the upper base plate and is used for fixing a pipeline; the lower backing plate is fixedly connected with the base through bolts and nuts, the screw adjusting mechanism is connected between the upper backing plate and the lower backing plate, and the distance between the upper backing plate and the lower backing plate is changed through the screw of the positive and negative rotation screw adjusting mechanism, so that the free adjustment of the height of the pipeline supporting device is realized; the device compresses the rubber gasket and the cushion block to the pipeline through the clamp and the upper cushion plate for the bolts, the rigidity of the rubber gasket and the cushion block is higher, and the vibration isolation effect is poorer; due to the creep property of rubber, the pressing force of the rubber gasket and the cushion block on the pipeline is gradually reduced along with time, so that the pipeline is not easy to be reliably fixed.
The Chinese patent 201620907406.2 proposes an adjustable elastic pipeline supporting crane with a limiting function, a pipeline fixing component of the supporting crane is identical to that of the Chinese patent 201721155680.X, the height adjustment is realized through a bidirectional threaded sleeve component, and an elastic limiting component is arranged below the bidirectional threaded sleeve component, so that the defect of vibration isolation effect of the pipeline elastic fixing component is overcome. Chinese patent 201420399482.8 discloses an adjustable elastic pipe clamp, which is characterized in that a rubber elastic layer is wrapped on a pipeline through two omega-shaped clamps, the height adjustment is realized by adopting a bidirectional threaded sleeve assembly similar to that of Chinese patent 201620907406.2, one end of the bidirectional threaded sleeve assembly is connected with the omega-shaped elastic clamp, and the other end of the bidirectional threaded sleeve assembly is connected with a shock absorber. The height adjustment technical schemes proposed by the two patents are realized by two-way threaded sleeve assemblies, the transverse rigidity of the installed pipeline is poor, and the defect that the pipeline pressing force caused by rubber creep is gradually reduced along with time also exists.
