[0002] At present, in the production and installation of large-diameter tower workpieces, due to the characteristics of large diameter and thin wall of tower workpieces, it is very easy for part of its structure to collapse due to its own gravity during transportation and hoisting. In addition, it is also very easy for the tower workpiece structure to be damaged due to external impact and collision, which affects the accuracy of the tower structure and easily generates stress concentration in the tower workpiece. In severe cases, it even causes damage to the tower workpiece, which seriously affects the safety and reliability of tower workpiece production, assembly and use. In addition, when assembling tower workpieces, it is often necessary to adjust the horizontal tower workpiece to a vertical state through hoisting, and high-altitude hoisting operations are often required. Due to the lack of effective load-bearing and positioning equipment for large and super-large tower workpieces, the tower workpiece is very easy to swing during the hoisting process. While increasing the deformation of the tower workpiece due to swinging and uneven force, it is also very easy to collide with surrounding equipment due to swinging and be damaged, and even cause safety accidents in severe cases.
