Embodiment 1

[0045] The invention provides a pipeline vibration-absorbing clamp with adjustable direction, see the attached figure 1 , including: clamp assembly and vibration-absorbing assembly;

[0046] See attached figure 2 , the clamp assembly includes: an upper clamp ring 1, a rubber pad 2, a lower clamp ring 3, a mounting bolt 4, a washer 5, an adjustment block 6, an adapter block 7 and a nut 8;

[0047] The upper clamp ring 1 and the lower clamp ring 3 are both semi-circular rings, and connecting plates are provided at both ends of the semi-circular rings;

[0048] The rubber pad 2 is a ring;

[0049] See attached Figure 4 , 5 , the adapter block 7 is provided with a central through hole and a threaded hole perpendicular to the central through hole, the number of the threaded holes is two or more;

[0050] The upper clamp ring 1 and the lower clamp ring 3 are docked to form an arc surface structure and are set on the outer circumferential surface of the rubber pad 2; two adapt...

Embodiment 2

[0065] See attached Image 6 , On the basis of Embodiment 1, the connecting plates at both ends of the upper clamp ring 1 and the lower clamp ring 3 of the clamp assembly are fixed on the bracket.

Embodiment 3

[0067] On the basis of Embodiment 1 or 2, the vibration-absorbing component can be designed to have two frequencies, so that the pipeline vibration-absorbing clamp can simultaneously reduce two line spectra.

Abstract

The invention provides a pipeline vibration-absorption clamping hoop with an adjustable direction, and belongs to the technical field of vibration noise control. The pipeline vibration-absorption clamping hoop with the adjustable direction comprises a clamping hoop assembly and vibration absorption assemblies. The clamping hoop assembly comprises an upper clamping ring, a rubber gasket, a lower clamping ring and conversion connecting blocks. The upper clamping ring and the lower clamping ring are installed on the external circumference surface of the rubber gasket in a sleeving mode after the upper clamping ring and the lower clamping ring are connected in a butting mode. The two conversion connecting blocks are arranged between the upper clamping ring and the lower clamping ring, and the two ends of each conversion connecting block are connected with the upper clamping ring and the lower clamping ring respectively. Each vibration absorption assembly comprises a cantilever rod, mass component end blocks and a mass component middle block, wherein the mass component middle block and the cantilever rod are connected through threads, and the mass component end blocks penetrate through the cantilever rod and then are fixed to the two ends of the mass component middle block. The vibration absorption assemblies are fixedly arranged in threaded holes of the conversion connecting blocks of the clamping hoop assembly through the cantilever rods respectively. The pipeline vibration-absorption clamping hoop is compact in structure and adjustable in vibration absorption direction, can effectively restrain pipeline spectrum vibration of ships, and is low in demand of the installation space and convenient to disassemble, assemble and maintain.

Description

technical field [0001] The invention belongs to the technical field of vibration and noise control, and in particular relates to a direction-adjustable pipeline vibration-absorbing clamp. Background technique [0002] The equipment on the ship - the pipeline is one of the important channels for vibration transmission. The vibration transmitted by the pipeline includes not only the prominent characteristic line spectrum caused by the operation of the equipment, but also the vibration caused by factors such as flow shock. Reducing the vibration transmitted by these pipelines is of great significance for improving the stealth performance of ships. [0003] For the broadband vibration of the pipeline, it can be effectively controlled by installing vibration isolation brackets; for the low-frequency line spectrum vibration of the pipeline, there is currently no simple and effective means to significantly reduce it. Therefore, objectively, there is a need for a pipeline clamp th...
