The invention discloses a hoisting control method and device for preventing a huge offshore blade from rotating and swinging. The hoisting control device comprises a computer control system, a real-time measurement feedback system, a crane, a goods stabilizing trolley, a driving motor and goods stabilizing steel ropes. According to the hoisting control method, a mechanical model of the huge bladeunder strong wind load is established through the computer control system, and after the measured wind load and the hoisting force of a hoisting rope of the crane are imported into a computer softwarecontrol system through a real-time measurement feedback system, the computer software control system analyzes the magnitude and direction of the pre-tightening constant tension of the goods stabilizing steel ropes; Based on the model and the sensing data, the optimal pre-tightening constant tension of the vector balance of the goods stabilizing steel ropes and the hoisting force is adjusted in real time, so that the blade is prevented from rotating, the goods stabilizing trolley and the blade are accurately controlled to be synchronously lifted to keep the horizontal position, and blade swinging caused by wind load is prevented. The blade mounting efficiency is improved exponentially, mounting is safer and more reliable, and personal safety of mounting workers is guaranteed.

    本发明公开了一种海上巨型叶片防转动和摆动的吊装控制方法及其装置,该装置包括计算机控制系统、实时测量反馈系统、吊机、稳货小车、驱动电机、稳货钢绳;吊装控制方法通过计算机控制系统建立大风载荷下巨型叶片力学模型,在实时测量反馈系统将测得的风载和吊机吊绳的起吊力导入计算机软件控制系统后,计算机软件控制系统解析出稳货钢绳的预紧恒张力的大小与方向,基于模型和传感数据,实时调整稳货钢绳与起吊力矢量平衡的最佳预紧恒张力,从而防止了叶片转动,精确控制稳货小车与叶片同步提升保持水平位置,防止风载造成的叶片摆动。本发明成倍提高了叶片安装效率,使安装更加安全可靠,为安装工人的人身安全带来保障。
