Embodiment Construction
[0033] The present invention will be further described below in conjunction with accompanying drawing.
[0034] see figure 1 , the method for measuring and analyzing the production process data of the offshore wind power large-diameter single pile of the present invention comprises the following steps:
[0035] In step S1, corresponding scanning stations are respectively set for the respective production links of the single-section pipe pile, the multi-section pipe pile and the whole pipe pile. The distance between stations is based on the actual performance of the laser scanner, and does not exceed the signal attenuation distance. The commonly used equipment is about 20 meters.
[0036] The offshore wind power monopile foundation adopts a large-diameter steel pipe pile structure. Each single pile is composed of pipe joints with different wall thicknesses and different lengths, and each pipe joint is rolled from steel plates.
[0037] For the production process of single-sec...

The invention discloses a measurement and analysis method for offshore wind power major-diameter single pile production process data. The measurement and analysis method comprises the following stepsof arranging each corresponding scanning site; placing target balls; on each scanning site, carrying out leveling operation of a laser scanner, and finishing data scanning; splicing all point cloud data in the same scene, and outputting a file of a point cloud data format; in BIM software, constructing a single-pile model; importing the single-pile model into reverse engineering software, and establishing a data extraction template for each production link; using the corresponding data extraction template to test a data extraction function, and forming a template library; establishing a serverside; sending each file of the point cloud data format to the server side; and by aiming at each file of the point cloud data format, calling the corresponding data extraction template in the template library by the server side, generating single-pile measurement data on batch, and exporting the single-pile measurement data. The measurement and analysis method has the advantages of being easy andconvenient to operate, high in data accuracy, comprehensive in data information and the like, and is suitable for quality analysis in a large steel component production process.
Description
technical field [0001] The invention relates to the technical field of measurement and analysis, in particular to a measurement and analysis method for production process data of large-diameter single piles in offshore wind power. Background technique [0002] With the rapid development of my country's offshore wind farm construction in recent years, single pile foundations have become a mainstream type of wind power foundation. This type of foundation adopts super-large diameter steel pipe piles. The pile diameter is generally φ6m~φ8m, and the maximum diameter can reach 10m. 60mm~80mm, single pile weight 900t~1100t. At present, the production of single piles of such ultra-large diameter and ultra-large wall thickness steel is relatively difficult. The rolling of thick steel plates, the splicing of pipe joints and the welding process of the whole pile have all broken through the traditional conventional steel structure technology. At present, the actual data of the single pi...
