Process for installing and positioning double-rudder sleeve and tail casting in segmented construction stage

Abstract

The invention discloses a process for installing and positioning a double-rudder sleeve and a tail casting in a segmented construction stage, which aims to provide theoretical support for the scheme on the premise that the overall precision level of the existing ship construction is greatly improved, the tail end surface of the FR8 assembly tail casting is not processed, namely, the tail end surface is fixed, and a small amount of deviation of the center line of a tail shaft can be adjusted by epoxy. According to the scheme, the purpose of segmented division is that the rudder sleeve is installed in place in the segmented construction stage, the rudder sleeve does not need to be hoisted in the later carrying stage, and the trouble of high-altitude operation is avoided; the distance between the tail end face and the central rib positions of the two rudderstocks is determined in the segmented construction stage, and all other works in the later stage do not affect the size, so that the time for positioning and secondary precise control in the later carrying stage is shortened, the corresponding high-altitude operation is reduced, and the construction safety is improved; paint damage and repair are reduced, multiple positions in the tail area are narrow in the position space and difficult in construction, and construction safety is greatly improved.

Description

technical field

[0001] The invention relates to the technical field of ships, in particular to a technology for installing and positioning double rudder sleeves and stern castings in a segmented construction stage. Background technique

[0002] The rudder sleeve is associated with the rudder system, and the tail casting segments are associated with the shaft system. Under normal circumstances, due to the accuracy deviation in the stages of ship construction, general assembly, loading, etc., and the accuracy requirements of the rudder system and shaft system are the highest in ship construction, usually at the millimeter level, so in order to ensure accuracy, Reduce the impact caused by the accumulation of precision deviations in segmented construction, general assembly, loading, etc., and the segment with tail casting and the segment with rudder system are usually divided into two segments, and they are hung separately. The rudder sleeve It is a separate hoisting during the...
