Truss-type floating raft vibration isolation device

Abstract

The invention relates to a truss-type floating raft vibration isolation device which is characterized by comprising bases arranged at two sides, wherein a triangular connection frame is installed on the bases through a vibration isolator; a truss is in the shape of a Chinese character 'men'; two sides at the upper part of the truss are connected with the triangular connection frame; the lower endof the truss is connected with a base plate; and the truss is vertically suspended between the two bases. According to the invention, the truss acts as an intermediate structure of a floating raft, the vibration reduction and vibration isolation effects are reinforced through the variation of wave types, multiple scattering and reflection to vibration waves by a horizontal rod, a vertical rod, anoblique rod and a spherical joint of the truss in the structure; simultaneously, particles are filled in the horizontal rod of a hollow structure, and the isolation vibration effect is reinforced further; and in additional, the spherical joint and rod pieces of the truss-type floating raft are detachable, under the condition that the space in a ship is narrow, the truss-type floating raft can be dismounted into components, then the components are transported to and installed in the ship, and convenience is provided for mounting and maintaining.

Description

technical field [0001] The invention relates to a vibration isolation device, in particular to a truss type floating raft vibration isolation device, which is used for vibration isolation control of ship equipment and other similar fields. Background technique [0002] Vibration isolation measures are usually used in the vibration control of ship equipment, which can be divided into single-layer vibration isolation, double-layer vibration isolation and floating raft vibration isolation according to their types. Single-layer vibration isolation is the simplest means of vibration isolation. Connecting vibration equipment to the structure through a vibration isolator is single-layer vibration isolation. Double-layer vibration isolation is developed on the basis of single-layer vibration isolation. The vibration equipment is connected to the intermediate mass through the vibration isolator, and then the intermediate mass is connected to the structure through the vibration isolat...

AI Technical Summary

Problems solved by technology

The vibration isolation mechanism of the plate frame raft body is single, and the vibration isolation means that can be applied are limited, so the vibration isolation performance of the floating raft vibration isolation device is limited
