Abstract

The utility model belongs to the technical field of vibration isolators, and particularly relates to a vibration isolator for reducing vibration noise of a large-diameter pipeline of a ship, which comprises a fixed base and a mounting lug plate, a vibration damper is arranged on the fixed base, and the vibration damper comprises a supporting unit, a vibration damping unit and a fixing unit. According to the vibration isolator capable of reducing the vibration noise of the large-diameter pipeline of the ship, the supporting ring assembly is fixed to the fixing base through cooperation of the threaded sleeve and the elastic pin, so that the function of supporting the pipeline is achieved, the effect of absorbing and eliminating vibration of the pipeline is achieved through the supporting ring assembly vulcanized through rubber and the elastic pin, and before the pipeline is placed, the upper hinged support is rotated, and the pipeline is placed. The movable pin is arranged on the fixed base and moves outwards on the lower hinged support with the movable pin as a shaft, so that a pipeline can be conveniently placed on the fixed base, then the upper hinged support is closed, the pipeline can be conveniently placed, operation is more convenient, and a rubber pad is arranged, so that the function of absorbing and isolating vibration is further achieved.
