Problems solved by technology

[0003] Generally, there is more than one ship under construction in the dock. When two ships are built in the same dock, one of them is in the state of launching, and the other usually only reaches the state of half-ship penetration. It cannot be reset after flotation, and the state before and after flotation is inconsistent. In order to ensure the accuracy of the lighting of the guy line, the lighting of the guy line of the rudder system is delayed until after the float. Affects the overall launch of the ship

Abstract

The invention provides a method for installing a semi-suspension rudder in a semi-floating state. The main steps are to determine the centerline of the rudder system through a reference target, an auxiliary target and an illumination device before the semi-ship floats, and then pierce and bore. Hole mark and reset mark, bore the lower rudder bearing and lower rudder button through the boring mark, install the processed rudder stock bushing and rudder pin bushing on the lower rudder bearing and lower rudder button after boring, and Install the steering gear base. After the above operations are completed, the half-boat is lifted. After the half-boat is lifted, the center line of the rudder system is reset first, and then the semi-suspended rudder is connected with the rudder stock through the cooperation of the rudder stock and the hydraulic nut. Quick installation of semi-suspended rudders. Through the method of the present invention, the design dimensions of the drawings can be guaranteed on the construction site, construction can be carried out according to the drawings, the installation accuracy can be ensured, and the ship construction efficiency can be effectively improved.

Description

technical field [0001] The invention relates to a method for installing a rudder system, in particular to a method for installing a semi-suspended rudder in a half-ship floating state. Background technique [0002] Usually, the lighting of the stay wires of the rudder system is carried out after the whole ship is penetrated and before the overall launch. Due to the complexity of the installation of the rudder system, the installation of the entire rudder system lags behind, which has a certain impact on the launch of the ship. At this stage, in order to improve the progress of ship construction, many shipyards advance the lighting process of the rudder system to half-ship penetration, so as to ensure enough time for the installation of the rudder system, and ensure the timely launching, undocking and subsequent system of the ship. Poor test. [0003] Generally, there is more than one ship under construction in the dock. When two ships are built in the same dock, one of them...
