Embodiment Construction

[0026] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods.

[0027] This embodiment provides a method for drawing the margin line of the hull section, which can draw the margin line before the hull section is closed, and then carry out hoisting and closing, thereby reducing the time required for hoisting, and reducing Surgical rate, the method includes the following steps:

[0028] S110. Calculation: Calculate the required theoretical data value: first find the three-dimensional coordinate value of the intersection point of the upper opening of the outer plate 1 in the figure and the rib position line on the drawing of the segmented structure of the hull, that is, the distance from the segmental centerline The half-width value, the height value of the upper opening of the outer plate 1 to the inner bottom decking 2, the slope value of the upper opening of the...

Abstract

The invention relates to the technical field of ship machining, in particular to a method for drawing a hull section margin line. The method includes the following steps of conducting calculation, wherein the theoretical data values of required points are found out on a hull section; arranging a station, wherein a total station is erected; drawing a frame line; drawing points, wherein the actual positions of the required points on the hull section are found out through the total station and connecting the points into a line, wherein all the points found out on the hull section are connected in a smooth mode. By means of the method, drawing of the section margin line can be finished quickly, and meanwhile the hoisting time is reduced.

Description

technical field [0001] The invention relates to the technical field of ship processing, in particular to a method for drawing a subsection allowance line of a hull. Background technique [0002] With the rapid development of science and technology, the technology of various industries is constantly updated, and the innovative application of new processes has greatly improved production efficiency and shortened the construction cycle. [0003] At this stage, the shipbuilding industry is gradually deepening and meticulously implementing precision management, and the construction accuracy of hull segments has been greatly improved. There is still a lot of leeway in the middle closing stage, considering many factors such as the situation of the big closing. However, a large number of large closing repairs lead to an increase in the damage rate of the ship's paint, which has a great negative impact on the construction of the ship. [0004] In the prior art, due to the considera...
