Flange alignment device for shaft end of wind power main shaft without damaging the conveying device

Abstract

The invention discloses a wind power spindle shaft end flange hole alignment device without damage to a conveying device. The device comprises a machine frame, a flange conveying device is arranged onthe working surface of the machine frame, and a lifting type limiting part is arranged at one end of the conveying device; the device further comprises rotary driving mechanisms for driving the flange to rotate, the rotary driving mechanisms are arranged on the two sides of the flange conveying device and are positioned below flanges; the device further comprises a flange storage rack provided with a flange storage table, and a storage table lifting mechanism for driving the flange storage table to ascend and descend is arranged in the flange storage frame; and the flange conveying device comprises a ball or a rolling column which is arranged on the working surface of the machine frame, the working face of the machine frame is obliquely arranged and can ascend and descend. According to the wind power spindle shaft end flange hole alignment device, the manual operation of aligning the mounting holes of the plurality of flanges before hoisting is reduced, the labor intensity of workersis reduced, the efficiency is high, and the safety is excellent; in addition, in the process of aligning holes, the flanges are not in contact with a lower conveying device, the conveying device is not damaged, and the service life of the lower conveying device is prolonged.

Description

technical field [0001] The invention relates to a device for aligning holes with a flange of a shaft end of a wind power main shaft without damaging a conveying device. 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 t...
