High-temperature-resistant and radiation-resistant hoisting frame structure for low-frequency vibration-absorbing mounting of steam pipeline

Abstract

The invention relates to a high-temperature-resistant and radiation-resistant hoisting frame structure for low-frequency vibration-absorbing mounting of a steam pipeline. The high-temperature-resistant and radiation-resistant hoisting frame structure comprises a supporting base and a pipeline clamp, wherein the pipeline clamp is of a structure consisting of an inner layer and an outer layer, and lined pipe clamps and a fastening pipe clamp for fixing and mounting a pipeline form the structure; two ends of the fastening pipe clamp are correspondingly fixedly connected to the supporting base through fastening parts, so that a mounting space is formed between the inner side surface of the fastening pipe clamp and the bottom surface of the supporting base; a pair of lined pipe clamps is arranged in the mounting space; and a plurality of elastic metal sheets are mounted in the peripheries of the lined pipe clamps. The high-temperature-resistant and radiation-resistant hoisting frame structure is simple, and convenient to use; the elastic metal sheets with 'high static and low movable' rigidity property are arranged to meet the requirement on low-frequency and vibration-absorbing mounting supporting of the pipeline; and the shortage that a traditional elastic damping material cannot meet the requirement on use of a nuclear power device in a high-temperature and a high-radiation environment can be overcome.

Description

technical field [0001] The invention relates to the field of pipeline control, in particular to a high-temperature and radiation-resistant steam pipeline low-frequency vibration isolation installation support and hanger structure. Background technique [0002] The vibration of the high-pressure steam pipeline system of the nuclear power plant is transmitted to the inner structure of the boat through the pipeline support hanger, causing vibration and noise radiation of the hull structure. Therefore, the structural design of the pipeline system support hanger is particularly important to control the vibration and noise transmission of the pipeline system. In addition, due to the local high temperature and high radiation characteristics of the nuclear power plant, the design of the pipeline support hanger needs to consider the applicability of the environment in addition to the requirements for good vibration reduction and isolation performance indicators. [0003] At present,...
