Description

technical field [0001] The invention belongs to the field of wind power steel pipe pile barrel rolling, and in particular relates to a light sensing monitoring and control system of a plate rolling machine and a wind power steel pipe pile barrel rolling process using the system. Background technique [0002] In recent years, offshore wind power generation, as a renewable clean energy, has been highly valued by governments, energy circles and environmental protection circles around the world. Wind power steel pipe piles, that is, the upright piles where wind turbines are embedded below sea level, mainly support wind turbines and their important Therefore, the production of wind power steel pipe piles is particularly important, and in the production process of wind power steel pipe piles, the rolling of wind power steel pipe piles has always been a prominent problem.

AI Technical Summary

Problems solved by technology

[0003] Domestic detection methods for large deformation plates of plate rolling machines are still relatively backward. The quality control problems of the cylinder during the forming process are prominent, and the cylindricity of the cylinder cannot be guaranteed. Online detection technology can improve the detection accuracy and reduce the labor intensity of workers. Greatly improve production efficiency, in order to keep pace with the development of global offshore machinery, it is imperative to automate the transformation of large-scale electromechanical-hydraulic integrated plate rolling machines

At present, the instruments used in the monitoring of shape and position errors at home and abroad include three-coordinate measuring machines, roundness meters, and shape measuring instruments. These instruments are expensive and have relatively high requirements for the testing environment. Single, not to be used for the measurement of shape and position errors of large-sized parts, it is highly restrictive

The traditional shape and position error measurement is mostly contact measurement. Commonly used measurement methods include: axis reference method, coordinate method, two-point method and three-point method, etc., but these traditional contact measurement methods have large comprehensive errors during measurement, The workload is heavy, the surface of the workpiece is easily damaged, and it is limited by the measurement environment.
