Ship block construction precision control method

Abstract

The invention relates to the technical field of ships, and discloses a ship block construction precision control method which comprises the following steps: S1, respectively mounting a front wire drawing frame and a rear wire drawing frame at two longitudinal ends of two transverse side positions away from a center line of a ship block; s2, drawing a steel wire between the front wire drawing frame and the rear wire drawing frame, wherein the distance between the steel wire and the center line is a first size; s3, respectively measuring the linear distance from each rib of the segmented opening to the steel wire, wherein the linear distance is a second size; s4, adding or subtracting the first size and the measured second size to obtain the distance between each rib of the measurement segmentation opening and the center line; and S5, adjusting the position of each rib of the segmented opening according to the calculated distance so as to control the half-width precision of the corresponding rib position of the segmented opening. The method has the advantages that the half-width precision of the corresponding rib position of the segmented opening can be controlled, the operation efficiency is high, and the ship size precision is high.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a method for controlling the accuracy of ship segmented construction. Background technique [0002] In the shipbuilding industry, the linear changes of the bow and stern parts of small and medium-sized ships and medium and large ships are relatively large. The peripheral walls of the semi-stereo decks of the main hull, the semi-stereo of the bow and stern buildings, the semi-stereo of the bridge, and even the semi-stereo of the superstructure all have linear shapes, and these segments are inverted on the frame with their own decks as the base. Pack. As we all know, for linear segments, the accuracy control is difficult to varying degrees, and the segment construction period is relatively long. [0003] At present, the adjustment and control of the peripheral wall of the above-mentioned type of segmented construction mainly include the auxiliary line method and the center line dra...

AI Technical Summary

Problems solved by technology

[0003] At present, the adjustment and control of the peripheral wall of the above-mentioned type of segmented construction mainly include the auxiliary line method and the center line drawing method, and the measurement is carried out by using a pendant hammer, a tape measure or a ruler, etc. , the tooling is blocked, and multiple people are required to cooperate

Therefore, low operating efficiency and large measurement errors are the main reasons for the heavy workload and long construction period of this type of segmental repair.
