Abstract

The invention discloses a vibration reduction ship pipeline cabin penetrating piece which comprises a pipeline and a cabin wallboard. The pipeline is externally provided with a cabin penetrating piece shell. The cabin penetrating piece shell is divided into an outer cabin penetrating piece shell body, a wavy shell body and an inner cabin penetrating piece shell body. The outer cabin penetrating piece shell body is connected with the cabin wallboard, the wavy shell body is connected with the outer cabin penetrating piece shell body at crest positions, and wavy fireproof rubber is arranged between the wavy shell body and the outer cabin penetrating piece shell body. Perpendicular connecting pieces are arranged on the inner cabin penetrating piece shell body and are provided with connecting rings, and parallel springs are arranged between the connecting rings and are parallel to the outer cabin penetrating piece shell body and the inner cabin penetrating piece shell body. Perpendicular springs perpendicular to the wavy shell body are arranged on the crests, and the parts, at the joint of the crests and the outer cabin penetrating piece shell body and at the outer portion of the outer cabin penetrating piece shell body, of the perpendicular springs are provided with bolts. A transverse partition plate is arranged at the middle portion of the cabin penetrating piece shell and is connected with the parallel springs. The vibration reduction ship pipeline cabin penetrating piece has the following beneficial effects that firstly, the vibration reduction capability of the pipeline cabin penetrating piece under collisions is improved; secondly, the vibration reduction capability of the cabin penetrating piece can be adjusted according to needs of different pipeline systems; and thirdly, the wavy shell body in the cabin penetrating piece can well reduce stress concentration.

Description

technical field [0001] The invention relates to a pipeline vibration damping device, in particular to a vibration damping ship pipeline penetration part. Background technique [0002] During its operation, the ship will inevitably face the problem of collision, which is directly related to the vitality of the ship. There are many pipeline systems on ships. The pipeline system is mainly used to transport various fluid media and its ancillary parts, pumps, monitoring instruments and valves. The pipeline system includes: pipelines, fittings (such as elbows, reducers, branch pipe connections, etc.), flanges, gaskets, bolted connections, valves, pipeline hangers and pumps, etc. Under the normal working conditions of the system, these supports can meet the thermal deformation and static stress requirements of the pipeline. However, except for the rigid and guide hangers, most of the spring hangers on the pipeline will deform and increase with the increase of external force. In s...
