Mounting method of semi-suspension rudder in semi-ship floating condition

Abstract

The invention provides a mounting method of a semi-suspension rudder in a semi-ship floating condition. The mounting method comprises the following main steps of: before semi-ship floating is performed, determining a center line of a rudder system through a reference target, an auxiliary target and a lighting device; punching a borehole mark and a reset mark, and boring holes in a lower rudder bearing and a lower rudder lug through the borehole mark; after hole boring is completed, mounting a machined rudder stock liner on the lower rudder bearing, and mounting a processed rudder pintle liner on the lower rudder lug; mounting a rudder machine base; after the operations are completed, performing semi-ship floating; after semi-ship floating is completed, firstly, resetting the center line of the rudder system; and then, connecting the semi-suspension rudder with a rudder stock in a matched manner through the matching of the rudder stock and a hydraulic nut, so that quick mounting of the semi-suspension rudder is achieved. Through the mounting method disclosed by the invention, design sizes in a drawing can be guaranteed at a construction site, and construction can be performed according to the drawing, so that the mounting accuracy is guaranteed, and the ship construction efficiency is improved effectively.

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...

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
