Abstract

The invention discloses a general assembly method of a rudder arm, which specifically includes the following steps: marking the intersection O of the center line of the rudder shaft and the center line of the hull on the deck; Install the bracing and wire hammer on the rudder arm; hoist the rudder arm to the position to be installed; adjust the position of the rudder arm to keep the anti-deformation gap between the wire hammer tip and the intersection point 0; according to the first rib, the first longitudinal The gap between the girder, the first outer plate and the rudder arm shall be trimmed correspondingly to the second floor, the second longitudinal girder and the second outer plate; the second floor, the second longitudinal girder and the second outer plate shall be Fix the rudder arm, then remove the bracing and positioning the backer. The method of the invention can realize accurate closing of the rudder arm, can improve the installation accuracy of the rudder arm, meets the installation accuracy requirement of the rudder arm, improves ship construction efficiency, and improves the construction environment.

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 ...
