Elastic supporting and vibration isolating device of ship pipeline system

Abstract

The invention discloses an elastic supporting and vibration isolating device of a ship pipeline system. The device comprises three functional components including a pipe clamp vulcanization component,two low-frequency vibration isolating components and a limiting component; the pipe clamp vulcanization component comprises an upper hoop-type pipe clamp and a lower hoop-type pipe clamp; an upper lining is arranged on the inner wall of the upper pipe clamp; a lower lining is arranged on the inner wall of the lower pipe clamp; the two low-frequency vibration isolating components are fixedly mounted on two sides of the lower pipe clamp in a lifting manner; and each low-frequency vibration isolating component comprises a middle connecting arc plate, a low-frequency vibration absorbing rubber block, a vibration absorber base and a protecting cover. The device adopts the double-layer vibration isolating structure, the low-frequency vibration isolating components adopt 30-60-degree cut vibration absorbing rubber, the rigidity in the vertical direction, the transvers direction and the longitudinal direction is reduced, the three-dimensional equal rigidity is realized, and the vibration isolating effect is good. The whole vibration isolating device is compact in structure and is convenient and easy to mount and maintain. The device is particularly applicable to application occasions of ships having relatively high noise and environmental adaptation requirements.

Description

technical field [0001] The invention belongs to the field of ship pipeline matching, and more specifically relates to an elastic support vibration isolation device for a ship pipeline system. Background technique [0002] In the hull, the common vibration isolation method for pipelines in the cabin is the horse foot vibration isolation device. The horse foot vibration isolation device is a support for the ship pipeline. The vibration energy flow of the pipeline system is transmitted along the pipe wall and the fluid medium in the pipe. Most of the energy will be directly transmitted to the hull through the installation horse foot of the pipeline system, causing the hull to vibrate and then Generate radiated noise. In other words, the pipeline support horse is an important channel for the vibration of the pipeline to the hull and structural noise. [0003] The high-performance elastic horse-foot vibration isolation device will more effectively isolate the vibration and soun...
