Metal rubber-disc spring all-metal composite hanger for pipeline vibration isolation and impact resistance

Abstract

The invention provides a metal rubber-disc spring full metal composite hanging bracket for vibration isolation and impact resistance of a pipeline. The metal rubber-disc spring full metal composite hanging bracket comprises metal rubber net cushions, disc-shaped springs, and a press cover, guide rods, bearing bolts and a shell which are used for supporting and fixing the elastic elements, and also comprises an extending rod, a universal spherical hinge and the like which are connected with the pipeline. The complex flexible and hard rigidity characteristics and large damping are realized by using the large bearing capacity and the flexible rigidity characteristic of the disc springs, the coulomb damping among the disc springs, the hard rigidity characteristic of the metal rubber net cushions, the coulomb damping among the disc springs and the metal rubber net cushions, and the air damping in the gaps between the guide rods and the bearing screw nuts. The metal rubber-disc spring full metal composite hanging bracket for the vibration isolation and impact resistance of the pipeline is compact in structure, light in weight and high in high-temperature environment adaptation, has higher static rigidity, lower dynamic rigidity and excellent damping property, is lower in vibration isolation frequency and is automatically limited, both the impact isolation and limiting functions are considered, and the impact acceleration response and the impact displacement response can be controlled in a reasonable range.

Description

technical field [0001] The invention relates to the technical field of design of vibration isolation and impact resistance devices, in particular to a metal rubber-disc spring all-metal composite hanger used for vibration isolation and impact resistance of pipelines. Background technique [0002] The impact protection performance of the gas turbine intake and exhaust piping system in the impact environment is a relatively weak link, which directly affects the operation function of the entire ship power system and is related to the vitality of the entire ship. The results of the actual ship explosion test show that the impact resistance of the pipeline system is an important issue that cannot be ignored, and its impact resistance is directly related to the vitality and combat effectiveness of the ship. [0003] In naval vessels, pipe supports are often used in conjunction with pipe hangers as elastic support elements for pipe systems. Its primary function is to provide struc...

Problems solved by technology

[0004] According to the materials used, the currently used pipe supports mainly use rubber vibration isolators as the load-bearing elements. Rubber vibration isolators are prone to deformation, and heat insulation pads need to be added to the connecting parts to meet high temperature requirements. Most of the current The support can only play the role of vibration isolation
