Tool for residual amount scribing in segment jointing during ship construction process

Abstract

The invention discloses a tool for the residual amount scribing in segment jointing during a ship construction process. The tool comprises a bottom plate, a screw, a height adjusting plate, a first nut and a second nut. The screw is vertically connected to the bottom plate; and the first nut and the second nut are arranged at the screw in threaded connection. A through hole is formed in the heightadjusting plate, wherein the diameter of the through hole is larger than the diameter of the screw and is smaller than outer diameters of the first nut and the second nut. The height adjustment plateis disposed parallel to the bottom plate; the screw passes through the through hole; and the first nut and the second nut are clamped at the two sides of the height adjusting plate. Besides, a slatepencil for scribing is fixedly arranged at the height adjusting plate. The tool has the following beneficial effects: the tool is used simply; the usage position is flexible; the application range cancover the full-position butt weld and the corner-joint weld; and the tool having a small size is carried conveniently.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, and in particular relates to a tool for marking margins when segments are closed during shipbuilding. Background technique [0002] With the advancement of science and technology, the rhythm of modern shipbuilding is also getting faster and faster. The length of time for a ship to be folded and built on the berth / dock largely affects the total construction period of the ship. How to shorten the hoisting time in the process of closing? The time of the segment depends entirely on the determination of the segment margin and the time for cutting the margin. Using convenient tooling and methods to better and faster divide the subsection margin will be very beneficial to the construction of the subsection closing stage, which is the key to shortening the construction period of the ship's berth / dock. [0003] The traditional margin marking method is to mark the margin position at both ends of the ...

AI Technical Summary

Problems solved by technology

[0004] First of all, the traditional method is complicated to operate. It is necessary to mark the margin mark on the side of all the plates with margin, and to draw the line to mark the line after determining the two ends of the margin line;

[0005] Secondly, the applicability of the traditional method is poor. For plates with a large line shape along the margin line direction, it is necessary to carry a sample strip to assist in drawing the margin line;

[0006] Again, whether it is pulling the wire or using the template strip to draw the margin line, more than two people are required for construction
