Method for installing rudder horn

Abstract

The invention discloses a method for installing a rudder horn. The method comprises the following steps: a, preparing an inverted-manufactured rudder horn-steering gear room platform subsection combined member; b, completing the welding operation of a main stern section, and after the main stern section is turned over, erecting and positioning the main stern section, and determining a subsection baseline surface; c, arranging a strengthening structure between a main deck and a steering gear room platform, then arranging an opening on the main deck; d, arranging an opening on a part (at which the rudder horn is arranged) of a hull baseplate, and carrying out rounded corner and surrounding structure strengthening on the opening of the baseplate; e, hoisting the erected rudder horn-steering gear room platform subsection combined member from the main deck, so that the rudder horn-steering gear room platform subsection combined member is hoisted from the main deck to the the composite member is below the rudder horn, then enabling the composite member to get out the opening of the baseplate; and f, welding the subsections of the steering gear room platform with other subsections. In the invention, through performing a rudder horn installation process in advance, the shipbuilding period is shortened, the accurate installation of the rudder horn is realized, the cost is reduced, and the efficiency is improved.

Description

technical field [0001] The invention relates to a method for installing a rudder arm. Background technique [0002] The rudder arm is usually installed during the berth construction stage, but the space at the stern of the ship during the berth stage is small, the hull structure is numerous, the construction environment is harsh, the assembly and welding is difficult, and the required period is long. From the perspective of the development trend of production design, the installation process of the rudder arm is advanced to segmental installation, which can effectively shorten the shipbuilding cycle and improve the construction environment. However, the hoisting area where the rudder arm is located is narrow, the hoisting mouth is smaller than the size of the assembly, and the installation space at the bottom of the assembly is very small. How to smoothly implement safe hoisting and precision installation to control deformation is the biggest difficulty. However, the domes...

However, the hoisting area where the rudder boom is located is narrow, the hoisting opening is smaller than the assembly, and the installation space at the bottom of the assembly is very small. How to smoothly implement safe hoisting and precision installation to control deformation is the biggest difficulty

However, the domestic technology of installing the rudder arm in sections is still immature, and there is no other experience to refer to
