Vibration isolation bracket of nuclear power station

Abstract

The invention discloses a vibration isolation bracket of a nuclear power station. The bracket comprises a pipeline, a pipe clamp, supporting rods and a bottom plate, wherein the lower part of the bottom plate is provided with a vibration isolation mechanism, the vibration isolation mechanism comprises an elastic device and a rigid device, the rigid device comprises a limiter and two connecting pieces, each connecting piece is fixedly connected with a supporting piece, an adjusting base plate is arranged between the bottom end of each connecting piece and the supporting piece, a pin shaft holeis formed in the upper end of the limiter and is inserted with a connecting pin shaft, and two ends of the connecting pin shaft are fixedly connected with the corresponding connecting pieces respectively. The vibration isolation bracket is simple in structure, the functional components used by the vibration isolation bracket can be additionally added on the basis of not damaging the structure of an original bracket, and the design and production cost is reduced; and in addition, the vibration isolation bracket not only has a good vibration isolation function, but also has a rigid supporting function under a special working condition, and the safety coefficient of a pipeline system is improved.

Description

technical field [0001] The invention relates to the technical field of vibration isolation devices, in particular to a vibration isolation bracket of a nuclear power plant. Background technique [0002] The shock-absorbing bracket is a kind of bracket with shock-absorbing effect that is often used in the fields of architectural design, electric power engineering, and seismic equipment. According to different places of use, it can be made of plastic, rubber, stainless steel and other materials, and has a variety of structures. And the use form, among them, in the process of anti-seismic design of pipelines in nuclear power plants, it is necessary to recheck the anti-seismic calculation of pipelines. The pipelines in nuclear power plants are very complicated, and the load of some main pipelines is very large, and seismic isolation structures are required to reduce pipeline vibration. And due to the particularity of the nuclear power plant site, this type of vibration isolation...
