Ship engine compartment raft frame

Abstract

The invention discloses a ship engine compartment raft frame which comprises a raft frame body, the raft frame body is composed of a base plate, vertical plates and a face plate, the vertical plates are connected to the two sides of the base plate, the horizontal face plate is connected to the top faces of the vertical plates, the positions, located on the two sides without the vertical plates, of the raft frame body are connected with horizontally-arranged transverse rods. The outer sides of the vertical plates are connected with transverse supporting mechanisms, the bottom of the raft frame body is connected with a longitudinal supporting mechanism, the shock absorption and noise reduction effects of the raft frame body are effectively improved through the transverse supporting mechanisms and the longitudinal supporting mechanism, meanwhile, the transverse supporting mechanisms and the longitudinal supporting mechanism can generate a linkage adjusting effect, in the ship sailing process, a proper damping effect can be obtained through adjustment according to the situation of a ship body, and when the ship body inclines, a good damping effect can also be guaranteed.

Description

technical field [0001] The invention relates to the technical field of a raft frame for a power cabin of a ship, in particular to a raft frame for a power cabin of a ship. Background technique [0002] The power cabin of a ship is the main engine room that provides power for the ship to sail in the water. Power equipment is installed on the raft of the power cabin. During this process, the noise mainly comes from the operation of the main and auxiliary machines and shafting in the power cabin, which is transmitted through the cabin raft, base, and raft to excite the shell, causing the shell to vibrate and radiate to the surrounding water medium noise; [0003] The existing power cabin raft frame cannot effectively slow down the mechanical vibration generated when the power equipment is working, nor can it play a certain role in blocking or slowing down the vibration when the vibration is transmitted from the power equipment to the power cabin raft; When there is a large sh...

AI Technical Summary

Problems solved by technology

[0003] The existing power cabin raft frame cannot effectively slow down the mechanical vibration generated when the power equipment is working, nor can it play a certain role in blocking or slowing down the vibration when the vibration is transmitted from the power equipment to the power cabin raft; When there is a large shake, the hull tilts, causing the raft frame and internal equipment to tilt as a whole. Since the gravity direction of the raft frame and internal equipment is always downward, the force transmission point changes, which is not conducive to the cushioning effect.
