Equipment floor pipe vibration isolation structure

Abstract

The invention provides an equipment floor pipe vibration isolation structure. The equipment floor pipe vibration isolation structure is composed of a pipe vibration isolation assembly installed below a pipe and a lower vibration isolation structure installed between the pipe vibration isolation assembly and a floor. The pipe vibration isolation assembly is composed of a pipe bearing support, an elastic vibration absorption pad and an upper adjustable spring vibration isolator. The pipe bearing support is an integrated assembly formed by welding an arc-shaped steel plate, force-bearing steel plates on the two sides and a stiffening plate. The lower vibration isolation structure is composed of a vibration isolation weight block, a bearing steel structure, a lower adjustable spring vibration isolator and a rubber anti-vibration pad and the vibration isolation weight block is an integrated assembly composed of a steel plate frame structure and a counter weight. The equipment floor pipe vibration isolation structure can effectively control solid structure transmission of pipe vibration and is high in vibration isolation efficiency. Moreover, the height of the vibration isolation structure can be adjusted according to needs and load balancing of related equipment and pipes is guaranteed.

Description

technical field [0001] The invention relates to a vibration and noise control device, in particular to an equipment layer pipeline vibration isolation structure for preventing pipeline vibration solid transmission. Background technique [0002] The fluid delivery pipeline of the equipment is an important part of the equipment system. As a good conductor of mechanical vibration, the vibration of the equipment system can be transmitted remotely along the pipeline. In particular, changes in the operating conditions of the medium in the pipeline will cause serious vibrations in some pipelines, and strong pipeline vibration will loosen the pipeline accessories, especially the connecting parts of the pipeline. Under the action of fluid exciting force, the pipeline itself will also generate vibration or even strong impact. It is usually used on pipelines of mechanical equipment equipped with elastic supports. It not only acts as an elastic support for the pipelines, but also has a...
