Embodiment Construction

[0010] Such as Figure 1-3 As shown, the present invention is a positioning method for the docking of two general sections of large dock shipbuilding, including the first general section 1 and the second general section 1 to be docked. The inventive method at first measures the following data of the 1st general section 1 docking surface 3, as image 3 As shown, measuring point P1 for molded width or molded depth, measuring point P4 for deck center, measuring point P3 for the outer plating of bilge, measuring point P5 for the center of inner and outer bottom plates, and measuring point P2 for the height of each knuckle of the inner shell plate from the center and baseline . Secondly, the present invention feeds the above-mentioned data back to the second general segment to provide positioning reference data for subsequent positioning of segmental positioning at the closing seam in the second general segment.

[0011] If the present invention wants to ensure the structural ali...

Abstract

The invention discloses a method for positioning butt joint of two total sections in large dock shipbuilding. The method comprises the following steps: firstly, measuring the following data of the butt joint surface of a first total section: a molded breadth or molded depth measuring point (P1), a deck centre measuring point (P4), each measuring point (P3) of an outside plate of a bilge, centre measuring points (P5) of an inner bottom plate and an outer bottom plate, and points (P2) for measuring heights from each break angle of an inner shell plate to the centre and a base line; and secondly, feeding the data back to a second total section so as to provide positioning reference data for the subsection positioning at the close seam when subsequently positioning the second total section. In the method, in order to reduce cutting and repairing work, a set of positioning process requirements on the subsection at butt point close seam of the two total sections in the large dock shipbuilding is provided, which realizes the butt joint of the two total sections effectively, improves work efficiency, and reduces working cost and working difficulty.

Description

technical field [0001] The invention relates to the shipbuilding industry, more specifically, to a positioning method for the docking of two general sections in shipbuilding. Background technique [0002] After the positioning of the two general sections, the structural misalignment of the butt joints often occurs, and there is a phenomenon of high and low or left and right misalignment. One of the reasons is that the positioning coordinate values ​​of the subsections at the seams where the two total sections are aligned are not the same. As a result, a large number of cuts have been made. [0003] The traditional practice of construction in the dock of the general section is to "do things differently", that is, the segmental positioning of the butt joints of the first general section does not take into account the segmental positioning of the butt joints of the second general section. The subsection positioning of the 2nd general section butt joint seam place also does no...
