Assembly and positioning device for wind power tower flange before transportation

Abstract

The invention discloses a wind power tower cylinder flange forming and positioning device before transportation. The device comprises a machine frame, a flange conveying device is arranged on the working surface of the machine frame, and a lifting type limiting baffle is arranged at one end of the conveying direction of the machine frame; the device also comprises flange lifting mechanisms, the flange lifting mechanisms are arranged on the two sides of the flange conveying device, and are positioned below flanges; rotary driving mechanisms for driving the flange to rotate are arranged on the flange lifting mechanisms; and the device further comprises a flange storage rack provided with a flange storage table, and a lifting mechanism for driving the flange storage table to ascend and descend is arranged in the flange storage frame. According to the wind power tower cylinder flange forming and positioning device before the transportation, the manual operation of aligning mounting holes of the plurality of flanges before hoisting is reduced, the labor intensity of workers is reduced, the efficiency is high, and the safety is excellent; and in the process of aligning hole, the flangesare not in contact with a lower conveying device, so that the service life of the lower conveying device is prolonged.

Description

technical field [0001] The invention relates to a pairing and positioning device for flanges of wind power tower tubes before transportation. Background technique [0002] At present, due to the large difference between the workpiece and the blank of the wind power flange, and the workpiece requires better comprehensive mechanical properties, the processing sequence is divided into blanking (sawing), heating, forging, reheating, ring grinding, stress relief annealing, Turning, drilling, manual chamfering. After the processing is completed, several wind power flanges of uniform specifications are generally stacked and lifted by hoisting slings. Since the flange has a center hole and mounting holes around the center hole, the lifting method is to manually wind the lifting wire rope around the wind power plant. After the position of the circular section of the flange is positioned, the lifting steel wire rope is connected to the lifting hook set on the loading equipment, and t...
