Embodiment 1

[0047] Such as figure 1 and figure 2 As shown, a high-damping nuclear power pipeline vibration-reducing and isolating bracket includes a pipe support 1 and a vibration-damping bracket. The vibration-damping bracket includes a first metal guide rod 2, a guide tube 9, a lever structure and a damping module. The guide The pipe 9 is arranged between the fixed panel 10 and the installation panel 11, a damping module is also installed between the fixed panel 10 and the installation panel 11, one end of the first metal guide rod 2 is connected to the pipe support 1, and the The other end of the first metal guide rod 2 is located in the guide tube 9 and is slidably connected with the guide tube 9, and the lever structure is hinged with the first metal guide rod 2, the fixed panel 10 and the damping module.

[0048] The lever structure includes a first connecting rod 3, a second connecting rod 4, and a third connecting rod 5, one end of the first connecting rod 3 and the second conne...

Embodiment 2

[0067] The difference between this embodiment and Embodiment 1 is that there are at least three lever structures, and correspondingly there are three damping modules.

[0068] In the present invention, the "up", "down", and "height" are all based on the orientation shown in the drawings.

Abstract

The invention discloses a high-damping nuclear power pipeline vibration reduction and isolation support and solves the technical problem that the vibration reduction capacity of a nuclear power pipeline support in the prior art is insufficient and needs to be further improved. The high-damping nuclear power pipeline vibration reduction and isolation support comprises a pipeline support and a vibration reduction support, the vibration reduction support comprises a first metal guide rod, a guide pipe, a lever structure and a damping module, the guide pipe is arranged between a fixed panel and an installation panel, the damping module is further installed between the fixed panel and the installation panel, one end of the first metal guide rod is connected with the pipeline support. The other end of the first metal guide rod is located in the guide pipe and is in sliding connection with the guide pipe, and the lever structure is hinged to the first metal guide rod, the fixed panel and the damping module. The high-damping nuclear power pipeline vibration reduction and isolation support has the advantages of being good in support vibration reduction performance, effectively protecting a nuclear power pipeline and the like.

Description

technical field [0001] The invention relates to the technical field of nuclear power pipeline support, in particular to a high-damping nuclear power pipeline vibration-reducing and isolating support. Background technique [0002] The nuclear power piping system is one of the important engineering structures widely used in modern nuclear power plants, and it is also an important transmission path of vibration and noise. Generally speaking, the vibration and noise of nuclear power pipelines mainly come from the vibration of excitation equipment and the flow of fluid inside the pipeline, and are transmitted to the foundation through the pipeline support. Nuclear power pipelines have higher requirements for vibration reduction due to the particularity of their transportation materials. If the vibration reduction is insufficient, it is very likely to damage the brackets and pipelines, which will lead to safety problems such as leakage. With the improvement of environmental requi...
