Embodiment Construction

[0032] The process of installing a rudder stock barrel in stages in the present invention will be further described in detail in conjunction with the accompanying drawings, in order to understand the application process of the method of the present invention more clearly, but it cannot be used to limit the protection of the present invention. scope.

[0033] like Figure 1~Figure 6 As shown, the design method for installing the rudder stock tube in stages in this embodiment includes the following steps:

[0034] S1, surveying and delineating the datum ground line, such as figure 1 As shown, use the total station to survey and draw the hull center line 1 and FR0 rib line 2 on the floor, the marking accuracy is ±1mm, find the intersection of the hull center line 1 and FR0 rib line 2, and draw the Mark the intersection point as the center point 3 of the rudder system, take the centerline of the hull 1 as the datum line, draw the longitudinal pier layout datum line 1-1 in parall...

Abstract

The invention discloses a processing method for installing a segmented staged rudder trunk. The processing method comprises the steps that S1, reference ground line assignment is conducted; S2, the level of rudder trunk segments is adjusted; S3, the rudder trunk is assembled and welded; S4, a false rudder is assembled and welded; S5, scattered parts are installed. According to the processing method, a conventional assembly stage or rudder trunk installation in a dock stage is brought forward to a segment stage to effectively improve building conditions and labor intensity, and accelerate the installation speed of the rudder trunk, so that the building period of a ship is effectively shortened, and the processing method is capable of greatly improving the installation precision of a shaft and rudder system of the ship to facilitate improvement of the overall level of precision shipbuilding and lean shipbuilding of a shipbuilding enterprise.

Description

technical field [0001] The invention belongs to the field of shipbuilding, and in particular relates to a process method for installing a rudder stock cylinder in stages. Background technique [0002] The rudder tube is an integral part of the flap rudder. Ships using flap rudders can improve their propulsion and maneuverability. When the rudder tube is welded to the hull structure, it is necessary to ensure its verticality, concentricity, and ellipticity of the inner wall. A series of precision control elements, and the false rudder structure connected to the rudder barrel, and the rest of the rudder blades have clear clearance requirements, and a series of precision control elements such as the installation height and levelness of the false rudder are also the objects that need to be guaranteed. At present, the installation of the rudder stock is generally carried out at the general group stage or the dock stage. This design method has the following disadvantages: [0003...
