Rudder blade fixing tool and ship

Abstract

The invention discloses a rudder blade fixing tool and a ship. The rudder blade fixing tool is used for fixing a rotatable top plate and a tail fin of a rudder blade; the rudder blade fixing tool comprises a first fixing part and a second fixing part which are connected fixedly; the upper end of the first fixing part is fixedly connected with a false rudder bottom plate of the ship; the lower end of the first fixing part is fixedly connected with the top plate; a first cutting position allowing cutting under water is arranged on the first fixing part; the second fixing part is connected with the tail fin; the position between the tail fin and the false rudder bottom plate is relatively fixed; a second cutting position allowing cutting under water is arranged on the second fixing part. Compared with the prior art, the rudder blade fixing tool disclosed by the invention can ensure ship launching safety and smoothness; moreover, rudder locking and unlocking operation is simple, and the workload of on-site construction is reduced.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a rudder blade fixing tool and a ship using the rudder blade fixing tool. Background technique [0002] The Xiamen University scientific research ship is an electric propulsion ship with double flap rudders. The ship is built on the berth, and when it is launched, it will slide faster, which will have a greater impact on the rudder blade. If the rudder blade swings, the ship will not be able to reach the designated position when it is launched and cause a relatively large safety accident. In order to ensure the safe and smooth launch of the ship, it is necessary to use tooling to temporarily lock the rudder blade firmly at the zero rudder angle position. [0003] The steering gear of the Xiamen University scientific research ship is a rotary vane steering gear, which cannot be locked by fixing the rudder stock inside the steering gear cabin, and the power system of the rud...

AI Technical Summary

Problems solved by technology

For the method of directly fixing the top plate of the rudder blade and the empennage by welding the steel plate to lock the rudder, when the rudder is released, the cutting position on the steel plate is limited, resulting in the inability to perform underwater cutting, which makes it very troublesome to remove the rudder; while for other non-welding fixed In this way, the fixing strength of the rudder blade will be affected. When the ship is launched, the rudder blade will be impacted by the water flow and the rudder lock will fail, causing the rudder blade to be damaged.
