Title:
FULLY-COATED TWO-STAGE SHOCK ABSORBER
Document Type and Number:
WIPO Patent Application WO/2022/252358
Kind Code:
A1
Abstract:
The present invention relates to the technical field of pipe vibration isolation devices, and relates in particular to a fully-coated two-stage shock absorber, which comprises a first-stage vulcanized pipe clamp assembly which fixes an upper pipe clamp and a lower pipe clamp by means of a pipe clamp connecting fastener so as to coat an upper lining rubber layer and a lower lining rubber layer therein; and further comprises rubber blocks for vibration isolation which are symmetrically arranged on the left and right sides of a bottom surface of the lower pipe clamp; and a second-stage low-frequency vibration isolation assembly which is composed of a V-shaped support seat and which is fixed to the bottom surfaces of the rubber blocks for vibration isolation, wherein the pipe clamp connecting fastener and the mounting position thereof are each coated with epoxy resin anti-corrosion coatings, and the remainder are subject to vulcanization treatment. Compared with the exiting technology, a fully-coated structure and a two-stage vibration isolation structure are used in the present invention, so that a better vibration isolation effect may be achieved, the amount of space occupied is reduced, and the weight of the components is reduced, and the anti-corrosion and insulation effect is also improved, and the service life of components is prolonged; in addition, the present invention has good application prospects in a ship system, and may also be popularized to nuclear power, petroleum and chemical engineering and other industries.
