Embodiment Construction

[0009] The present invention is a method for underwater installation of a ship's rudder system, which includes the following steps: step 1, firstly position and install the rudder sleeve before the ship is launched, and pass the inspection of the ship's rudder axis together, and then install the rudder stock and rudder blades Assemble it on the platform or tire frame to make it an integral unit. After the ship enters the water, install the rudder system under the mooring state. Before hoisting, the exposed surface of the rudder stock must be protected by grease, wrapping kraft paper or rubber; Step 2. Adjust the trim of the ship by adjusting the ballast condition of the ship, so that there is a distance between the bottom plane of the rudder sleeve and the water surface and keep it parallel to the water surface as much as possible. The distance between the bottom plane of the rudder sleeve and the water surface is at least 1M , so that there is enough water depth to ensure that...

Abstract

The invention discloses a method for the underwater installation of a ship rudder system, which comprises the following steps: 1. installing a rudder sleeve on the ship before launching, testing together with a rudder shaft, assembling a rudder stock and a rudder blade to a unit, installing the rudder system in mooring after launching; 2. regulating the ship trim by regulating ship ballast status; 3. horizontally moving the rudder blade and the rudder stock immediately below the rudder sleeve; 4. using the hand chain hoist of a tackle lifting mechanism at the ship stern to horizontally move the rudder stock/ the rudder blade as a whole immediately below the rudder sleeve and meanwhile raising the hand chain hoist of a rudder cabin to lift the rudder blade to the top surface which has a certain distance with the bottom surface of the rudder sleeve; 5. sleeving lower rudder carrier parts on the rudder stock; 6. continuing to raise the rudder stock and the rudder blade, and installing a rudder carrier, a actuator and a jump stop block; 7. disassembling the tackle lifting mechanism at the ship stern, checking the whole rudder system, and finishing the whole work flow.

Description

technical field [0001] The invention relates to a method for underwater installation of a ship's rudder system. Background technique [0002] In the process of ship manufacturing and installation, it is often encountered that the berth cycle is tight, and the rudder system installation in the current ship manufacturing process must be installed before launching, but when the ship berth is tight, the ship’s manufacturing and installation The process stops, which may interrupt the ship manufacturing and installation process, and bring troubles to the ship manufacturing and installation. Contents of the invention [0003] The invention provides a method for underwater installation of a ship's rudder system, which can not only ensure the safety of equipment, but also quickly and accurately complete the underwater installation project of the rudder system. [0004] The present invention adopts the following technical solutions: a method for underwater installation of a ship's ...
