Fast positioning method of ship anchor platform

Abstract

The invention discloses a fast positioning method for a ship's anchor platform, which includes the following steps: anchor platform angle positioning measurement: repeating the measurement operation at the anchor platform surface, correcting the anchor platform angle once, positioning and measuring data once, and using a fixed transfer station patch to perform positioning and measurement operations 3 to 5 times, at the same time, input the measurement data of the anchor platform into the anchor platform angle inspection program, adjust the anchor platform angle according to the calculated value, until the anchor platform angle is adjusted to within 0.3 degrees before welding, and at the same time directly use the fixed transfer station target to carry out the anchor platform Angle measurement. The invention is simple to operate, solves the problem of waste of man-hours and labor caused by repeated measurement, saves man-hours and manpower; reduces the measurement error caused by repeated complete measurement, improves the accuracy of measurement data; at the same time reduces the number of anchors The wait-for-work phenomenon of positioning correction improves the positioning efficiency of the anchor platform and improves the production efficiency.

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.

[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-select the position to place the movable target to carry out the transfer operation, and the angle positioning measurement of the anchor platform needs to carry out 3-5 measurement operations and margin cutting. There are too many repeated measurement operations and multiple measurements The position of the target at the transfer station is not fixed, the measurement data has large errors and low accuracy; there are serious labor phenomena such as the cutting of the anchor chain pipe allowance, which wastes manpower;

[0003] Therefore, in the existing technology, there are too many repeated measurement operations in the anchor platform angle positioning measurement process, and the unfixed target of the transfer station leads to the problem of large measurement data errors; there are problems of measurement man-hours and manpower waste caused by repeated operations in the positioning measurement process ; and there is a serious problem of waiting for workers due to allowance cutting
