Final assembly method of ship shafting and rudder system

Abstract

The invention relates to a final assembly method of a ship shafting and a rudder system. The final assembly method comprises first performing expansion and final assembly to relative subsections of the shafting of the ship on a final assembly platform so that the relative subsections of the shafting become a shafting block, performing expansion and final assembly to relative subsections of the rudder system so that the relative subsections of the rudder system become a rudder system block, inspecting the manufactured shafting block and the rudder system block until the shafting block and the rudder system block fully meet the construction requirements, performing hole boring to the shafting and the rudder system respectively according to the shafting center line of the shafting block and the rudder system center line of the rudder system block, performing alignment and lap welding to the manufactured shafting block and the rudder system block on the final assembly platform, installing the shafting and the rudder system, and finally integrally lifting the shafting block and the rudder system block which are integrated by lapping into a dock so that the shafting block and the rudder system block and other blocks are lapped into a main ship body. The method improves manufacturing precision and quality of the shafting block and the rudder system block of the ship, deformation of the shafting block and the rudder system block of the ship in the lapping process is effectively controlled, and degree and progress of final assembly shipbuilding are improved.

Description

technical field [0001] The invention relates to ship building, in particular to a general assembly method of ship shafting and rudder system used in the ship building process. Background technique [0002] In the current ship construction, it is necessary to center the shafting and rudder of the ship, then bore the hole, and finally install it. After the segmental welding below the deck is completed, the tightness of the double bottom compartment is completed, and the baseline assessment is submitted, the shafting and rudder systems are to be centered respectively. [0003] In the existing technology, the shafting assembly, the rudder assembly and the subsequent loading and welding are all carried out in the dock. Since the alignment of the shafting and rudder has relatively high requirements on the loading state, it often takes more time In order to complete the work of the general group, this leads to a relatively long service life of the dock, which affects the speed...

[0003] In the existing technology, the shafting assembly, the rudder assembly and the subsequent loading welding are all carried out in the dock. Since the alignment of the shafting and rudder has relatively high requirements on the loading state, it often takes more time In order to complete the work of the general group, this leads to a relatively long service life of the dock, which affects the speed and progress of ship construction.
