A hinged installation method for a hull steel structure

Abstract

The invention discloses a hinged installation method of a hull steel structure, relating to the technical field of ship manufacturing, and solving the technical problem that some steel structures occupy more dry dock positions in the construction process, including steps: A. the hull steel structure is produced in segments; B. mapping a steel structure segmentation line on the ship main body; C. installing steel structure segment supporting tools on the ship main body; D. hoisting and fitting the steel structure segments, and positioning and moving the steel structure segments; E. hinges are arranged between the steel structure segments and the ship main body, and the installation position and the installation angle of the hinges ensure the turning route of the steel structure segments; and F, moving the main ship body to the outside of the dry dock, and hoisting andturningsteel structure segmentsforautomatic positioning and installation. According to the method, fitting and installation of the steel structure segments are completed in dock stage, and turning and fitting can be carried out by using small-tonnage hoisting equipment, automatic positioning of the steel structure segments is realized by using the hinges, therefore installation precision is improved, and dock construction period of a ship is shortened.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a method for segmented installation of a ship hull steel structure by using hinges. Background technique [0002] At present, in the installation process of the existing ship main structure, some bulk parts with simple structure but occupying more dock space resources, such as the skirt structure in the hull of the floating dock, when such bulk parts of the main hull structure are closed in the dock There are the following problems: (1) The docking workload of bulk hull structural parts is small, but it occupies a relatively large docking position, which cannot make reasonable use of the docking space and reduces the use of the dry dock, the core benchmark facility of the shipyard Efficiency and unit output value; (2) Bulk hull structures generally require more complicated hoisting and positioning work, so it takes a lot of time and prolongs the ship manufacturing period; (3...
