Description
Technical Field
The invention belongs to the technical field of pipeline fastening and supporting on ships and ocean operation platforms, and particularly relates to a vibration isolation horse leg for pipelines.
Background
Vibration reduction of a pipeline system is a difficult problem of vibration reduction of an existing ship auxiliary machine system, and is a weak point for vibration control of the ship auxiliary machine system. The elastic horse leg is one of the main technical means of pipeline vibration reduction. The elastic horse leg is mainly based on a single-layer vibration reduction system at present due to size and weight, but the vibration reduction effect is difficult to meet the requirement of a low-noise ship.
In order to further improve the vibration isolation effect, the Chinese invention patent is that in 2019, 4 months and 19 days: the elastic supporting vibration isolation device (publication number CN109654300 a) of the ship pipeline system discloses an elastic supporting vibration isolation device of the ship pipeline system, which comprises three functional components: pipe clamp vulcanization assembly, low frequency vibration isolation assembly and spacing subassembly. The pipe clamp vulcanizing assembly comprises an upper pipe clamp and a lower pipe clamp with upper and lower two clamp type, wherein an upper inner liner is arranged on the inner wall of the pipe clamp, a lower inner liner is arranged on the inner wall of the lower pipe clamp, and two low-frequency vibration isolation assemblies are respectively and fixedly arranged on two sides of the lower pipe clamp in a lifting mode; each low-frequency vibration isolation assembly comprises a middle connecting arc plate, a low-frequency vibration damping rubber block, a vibration damper base and a protective cover. The invention adopts a double-layer vibration isolation structure, wherein the low-frequency vibration isolation element adopts 30-60-degree shearing vibration damping rubber, reduces the vertical, transverse and longitudinal rigidities, realizes three-dimensional equal rigidity, and has good vibration isolation effect.
The rubber block has the main advantages of high-frequency structure vibration isolation, impact resistance and sound insulation performance, but the rubber block has small elastic modulus, and is a nonlinear elastic material. Therefore, the natural frequency of the rubber block is higher, and the vibration reduction efficiency of low-frequency structural noise is lower. Whereas the device layer pipeline effects are mainly solid structure propagation of pipeline vibration, mainly at low frequencies. The vibration isolation device is mainly used for vibration isolation through the low-frequency vibration isolation assembly, can be still considered as a single-layer vibration isolation system in practice, and is difficult to effectively improve compared with the single-layer vibration isolation system in vibration isolation effect. Therefore, aiming at the practical requirement of vibration reduction and noise reduction of low-noise ships, a double-layer vibration isolation horse leg with a middle mass body is urgently needed, and the vibration reduction effect of a pipeline is effectively improved.
