Composite vibration damping type pipe hanger

Abstract

The invention discloses a composite vibration damping type pipe hanger. The hanger comprises an upper pipe clamp body and a lower pipe clamp body, wherein the upper pipe clamp body and the lower pipeclamp body are connected by bolts and nuts arranged at the clamp ends of the the upper pipe clamp body and the lower pipe clamp body, a gasket is arranged between the clamp ends of the upper pipe clamp body and the lower pipe clamp body, a base is arranged at the top of the upper pipe clamp body, an oil cylinder with a piston arranged inside is fixedly connected to the base, the cylinder body of the oil cylinder is fixedly connected with the base, the piston comprises a piston cover and a piston rod, and the top end of the piston rod is fixedly connected with a base plate above the oil cylinder. According to the hanger, the design is novel, the structure is stable and the service life is long; a rubber ring is arranged between the upper pipe clamp body and the lower pipe clamp body, so that a first vibration damping device is formed, and the small vibration can be effectively controlled; the oil cylinder and the piston rod and the piston cover are matched with each other, so that the large-amplitude vibration and impact can be effectively buffered, and a second vibration damping device is formed; and according to the double vibration damping devices of the hanger, a pipeline can beeffectively prevented from being damaged, and the high requirement for vibration damping of a cruise is met.

Description

Technical field [0001] The invention relates to the technical field of vibration damping devices, in particular to a composite vibration damping type pipe hanger. Background technique [0002] At present, the mainstream damping pipe hanger on the market is a rubber damping type, and its main structure is a pipe clamp, a rubber ring, a connecting rod, and a backing plate. It is widely used for ordinary ship types, but still has the following shortcomings: [0003] 1. Rubber has a limited service life and is easily affected by the environment, and is easy to age and harden. [0004] 2. When large vibration or impact occurs, the connecting rod is prone to buckling deformation. [0005] 3. Cruise ships have extremely high requirements for vibration, and the vibration reduction effect of general tube hangers cannot meet the requirements of cruise ship vibration and noise. [0006] In order to meet the current design requirements of multiple performance levels and goals, it is of great sign...

AI Technical Summary

Problems solved by technology

[0007] Aiming at the shortcomings and deficiencies of the above-mentioned existing pipe hanger vibration reduction, the purpose of the present invention is a composite vibration-damping pipe hanger, which solves the problems of limited service life of the existing rubber, inability of the connecting rod to withstand large-scale vibration or impact, It is difficult to meet the vibration reduction requirements of cruise ships
