Ship anchor chock quick positioning method

Abstract

The invention discloses a ship anchor chock quick positioning method which comprises the following steps: anchor chock angle positioning measurement: repeating measurement operation at an anchor chocksurface, performing positioning measurement of data once every time the angle of the anchor chock is corrected, performing positioning measurement operation for 3-5 times by using a fixed transfer station patch, and inputting anchor chock measurement data into an anchor chock angle inspection program; and adjusting the angle of the anchor chock according to the calculated value until the angle ofthe anchor chock is adjusted to be within 0.3 degree before welding, and directly measuring the angle of the anchor chock by using a fixed transfer station target. The method is simple to operate, solves the problem of labor hour and labor waste caused by repeated measurement, and saves the labor hour and labor; measurement errors caused by repeated and complete measurement are reduced, and the accuracy of measurement data is improved; meanwhile, the waiting phenomenon of anchor chock positioning correction is reduced, the anchor chock positioning efficiency is improved, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of anchor platform angle positioning and measurement in the ship building process, in particular to a fast positioning method for ship anchor platforms. Background technique [0002] In the process of ship construction, the angle positioning and installation of the anchor system segmented anchor platform is to measure the angle positioning of the anchor platform after the accuracy of the anchor system segment is completed before welding. Operation and margin cutting, the final angle is controlled within 0.3 degrees. During the angle positioning measurement process, a complete measurement must be carried out each time, that is, after the position of the structural surface is measured once, two movable rotating targets are used to carry out the transfer operation. Measuring the four measurement points of the outer plate and the anchor platform panel for the table position; the interval between each positioning measureme...

[0002] In the process of ship construction, the angle positioning and installation of the anchor system segmented anchor platform is to measure the angle positioning of the anchor platform after the accuracy of the anchor system segment is completed before welding. Operation and margin cutting, the final angle is controlled within 0.3 degrees. During the angle positioning measurement process, a complete measurement must be carried out each time, that is, after the position of the structural surface is measured once, two movable rotating targets are used to carry out the transfer operation. Measuring the four measurement points of the outer plate and the anchor platform panel for the table position; the interval between each positioning measurement operation is between 5-10 hours, and a single anchor platform angle positioning measurement takes about 2 hours, and the time cost is relatively large, while a single Before the positioning measurement operation, it is necessary to re-
