Jumping stopping machine based on hanging rudder of vessel

Abstract

The invention discloses a jumping stopping machine based on a hanging rudder of a vessel. The jumping stopping machine comprises a jumping stopping machine body 9, wherein the jumping stopping machinebody 9 comprises two connecting groove plates 10 which are mutually and symmetrically arranged; ear plates 11 are respectively arranged on two sides of each of the connecting groove plates 10; each ear plate 11 is fixed to the corresponding connecting groove plate 10; through holes 12 are formed in a housing of each ear plate 11; and a screwing piece 13 matched with each through hole 12 is arranged on each through hole 12 in a corresponding manner. The jumping stopping machine disclosed by the invention is directly mounted on a rudder stock 2 in a sleeving manner through the two connecting groove plates 10 which are symmetrically arranged, the ear plates 11 are respectively welded to two sides of each of the connecting groove plates 10, while in use, the jumping stopping machine body of the structure is mounted between a lower rubber carrier sealing plate 5 and flanges of a rudder blade 1, and the two connecting groove plates 10 are fixedly fixed to the rudder stock 2 through the screwing pieces 13; the rudder blade 1 can be effectively prevented from moving up and down in stormy waves by the jumping stopping machine of the structure, and an upper rudder carrier is protected frombeing destroyed by the rudder stock 2, so that the safe navigation of the vessel is guaranteed; and the jumping stopping machine has the characteristics of being simple in structure, convenient to construct, quick in mounting, and can be repeatedly utilized.

Description

technical field [0001] The invention relates to a safety navigation protection device for a ship, in particular to a jump stop device based on a ship's suspended rudder, and belongs to the technical field of the ship industry. Background technique [0002] When the ship is sailing, especially when it encounters strong wind and waves, the rudder blade will move up and down due to the impact of waves, so that the rudder stock installed on the rudder blade will also shake up and down or left and right, and then make the whole set of rudder The device produces irregular vibrations, affecting the stability of the rudder device. [0003] In order to ensure the stability of the ship's operation, a jump-stopping device will be installed on the rudder blade of the hanging rudder during ship manufacturing. In the prior art, the stopper for hanging the rudder generally adopts a section of round steel or iron block, and the round steel or iron block is welded to the flange of the rudde...

AI Technical Summary

Problems solved by technology

This method is difficult to construct, and the round steel or iron block used is easy to wrap the fishing net and fishing rope, and the protection effect on the upper rudder bearing is relatively limited, that is, the rudder blade of the suspended rudder has poor protection.
