Abstract

The invention discloses a general assembly method for a rudder horn. The general assembly method specifically comprises the following steps that an intersection point O of a rudder shaft center line and a hull center line is marked on a deck; a positioning backer is arranged at a to-be-installed position of the rudder horn; a pull support and a plumb bob are arranged on the rudder horn; the rudderhorn is lifted to the to-be-installed position; the position of the rudder horn is adjusted, so that a reversed deformation gap is kept between the plumb bob tip and the intersection point O; according to a gap between a first rib plate and the rudder horn, a gap between a first longitudinal truss and the rudder horn, and a gap between a first outer plate and the rudder horn, a second rib plate,a second longitudinal truss and a second outer plate are correspondingly cut; and the second rib plate, the second longitudinal truss and the second outer plate are fixed to the rudder horn, and thenthe pull support and the positioning backer are disassembled. According to the method, accurate closing of the rudder horn can be realized, the mounting precision of the rudder horn can be improved, the installation precision requirement of the rudder horn is met, the building efficiency of a ship is improved, and the construction environment is improved.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a general assembly method of a rudder arm. Background technique [0002] In the manufacture of large ships, the rudder arms are all installed in sections, but in the current production stage, the accuracy of the segmented installation is high, because the rudder arms are mostly cast steel and thick plates, and contain certain wires. Type, once the installation deviates, after welding, the deformation will be large, the accuracy cannot meet the requirements, and it is difficult to carry out construction changes for thick plates after welding. Since the floor plate and the outer plate need to be closed with the rudder arm, the edge line type of the floor plate, stringer and outer plate should match the line type of the rudder arm, and the floor plate, stringer and outer plate cannot be cut by CNC . At present, during on-site construction, the floors, girders or outer plates ...
