Embodiment Construction

[0022] Below in conjunction with specific implementation mode, the technical scheme of the invention is further described:

[0023] A method for marking a line with a water gauge on an inclined berth, comprising the following steps:

[0024] S1. In real ship positioning, due to the bottom deflection caused by the large closing of the berth, the original theoretical baseline cannot be followed, and the revised baseline must be used. Usually, the mean value of the bottom deflection is used as the baseline, and a horizontal hose is used to adjust the bottom of the ship. Each measurement point of the deflection shall be measured and submitted to the shipowner and ship inspection for inspection to determine the baseline.

[0025] Beside the left side of the berth, at the intersection of bow water gauge rib level line 2 and straight section line 1, at the intersection of amidship water gauge rib level line 2 and straight section line 1, and at the intersection of stern water gauge r...

Abstract

The invention relates to a method for marking lines with a water gauge on an inclined berth. Read the reference point; S3, stick the tape on the outer plate; S4, use the total station to record the scale of the tape on the rib line of the water gauge and the height value corresponding to the scale of the tape, and draw the scale of the water gauge on the outer plate point; S5, according to the symmetry of the hull, use the data in S4 to draw the water gauge scale on the other side; S6, the water gauge gets three water scale scale points at the bow, midship, and stern, and uses the total station to measure the three water scale points. After the points are read, a waterplane surface is generated. The method of the present invention can quickly and accurately draw the scale of the water gauge, avoiding the problems of long operation time, complicated operation, and low operation accuracy of the traditional method, and can be widely used in the water gauge and waterline marking of the hull on the inclined berth. Pick.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a marking method with a water gauge on an inclined berth. Background technique [0002] With the advancement of the modern shipbuilding model, the efficiency of shipbuilding has been continuously improved, and the berth cycle has been continuously shortened. How to carry out a series of tasks such as surveying and planning of waterlines and water gauges, inspection, posting, assembly, welding and grinding, etc. Finishing and polishing of the outer panel paint before painting has become a bottleneck that urgently needs to be broken through before the hull is launched. [0003] The traditional water gauge marking is to erect three giant rulers near the marking positions of the bow, midship, and stern respectively, and then use a horizontal hose to draw the water scale scale line horizontally. This method is slow in construction progress and requires many personnel. , Low scribing effic...
