A measurement method for simulated loading of a ship in the large closing stage

Abstract

The present invention discloses an analog carrying measurement method for a ship during the hull section joining process. The method comprises the steps of S10, selecting several reference points on a strong structural position of a broadside rear segment and marking the reference points; S20, measuring the morphological structure of the broadside rear segment and measuring the reference points in the step S10 at the same time to obtain a first batch of measurement values; S30, assembling the broadside rear segment with a bilge part segment, and measuring an L-shaped fracture formed between the broadside rear segment and the bilge part segment with the reference points as a reference to obtain a second batch of measurement values; S40, importing the first batch of measurement values and the second batch of measurement values into a processing software, combining the two batches of measurement values, plotting as required and forming simulated structural drawings; S50, judging whether the size of the L-shaped fracture meets an installation size of a broadside front segment or not based on the simulated structural drawings. According to the invention, the method has fewer measurement steps, and is high in working efficiency.

Description

technical field [0001] The invention relates to the technical field of shipbuilding, in particular to a measurement method for simulating loading of a ship during the large closing stage. Background technique [0002] At present, when the ship's cargo oil tank area is closed, it is necessary to first assemble the side rear section (GS rear section) of the ship's cargo oil tank area with the bilge section (BG section). An L-shaped fracture is formed between the bilge sections, and then the side front section (GS front section) is assembled at this L-shaped fracture. In the big closing stage, not only the complete measurement of the entire part is required after the final assembly, but also the L-shaped fracture needs to be measured before the section is assembled before the side is assembled. The existing measurement methods have the following defects: (1) There are repetitive operations in the two measurement operations, and in the assembly process, due to various reasons s...

Problems solved by technology

The existing measurement methods have the following defects: (1) There are repetitive operations in the two measurement operations, and in the assembly process, due to various reasons such as the complexity of the job site and partial blocking of the line of sight by other objects, it is often impossible to Accurately measure the target data completely; (2) During the final assembly process, the surveyors need to carry out a lot of high-altitude operations to complete the measurement. However, at this stage, the erection of scaffolding is not necessarily complete, and the phenomenon of partial scaffolding often exists , which brings great potential safety hazards to the measurement work; (3) The measurement work needs to be carried out on the unfinished hull during the final assembly process. At this time, there are often many other types of work in the work area, especially assembly and grinding operations. The execution of these operations has a great impact on the accuracy of the total station measurement data, which in turn affects the accuracy of the simulated loading operation data, which may lead to the failure of the simulated loading operation in this area
