Self-limiting adjustable low stiffness pipeline elastic support

Abstract

The invention relates to a self-limiting adjustable low stiffness pipeline elastic support which comprises pipeline mounting assemblies, and a nonmetal thickness adjusting sheet, wherein a pipeline mounting assembly is formed by two pipeline mounting supporters, a semicircle pipeline snap ring, and a plurality of nonmetal vibration damping elastic members through a bolt mounting or a mould integrating; the semicircle pipeline snap ring is fixedly connected between the two pipeline mounting supporters through the plurality of nonmetal vibration damping elastic members; nonmetal anti-collision sheets are stuck on the inner surface of the pipeline mounting supporters; the nonmetal thickness adjusting sheet is stuck on the inner surface of the semicircle pipeline snap ring; the two pipeline mounting assemblies fixes a pipeline between the two semicircle pipeline snap rings through the bolt to form pipeline elastic supporters; and the pipeline elastic supporters are arranged on two base through four height-adjustable bolt assemblies. By utilizing the low shearing rigidity property of a nonmetal vibration damping elastic material and the height-adjustable bolt assemblies, the problems that the pipeline broadband vibration isolation and the height tolerance generated during the pipeline installation are solved.

Description

technical field [0001] The invention relates to a technology for controlling vibration and noise of a ship's pipeline, in particular to a pipeline elastic support that can be used for vibration isolation of a ship's pipeline. Background technique [0002] In view of the increasing emphasis on marine environmental protection, the control of ship vibration and noise has received extensive attention. After the vibration transmitted by the mechanical equipment along the machine feet is effectively isolated, the vibration transmitted through the pipeline gradually becomes prominent, and corresponding control measures need to be taken. At present, in the control of pipeline vibration and noise, the method of combining flexible pipe joints and elastic supports is mainly used to effectively isolate the transmission of pipeline vibration in the system. Among them, the installation of high-performance pipeline elastic supports is to reduce pipeline vibration transmission. an effectiv...
