Automation device for wind power spindle flanges before hoisting

Abstract

The invention discloses an automation device for wind power spindle flanges before hoisting. The automation device comprises a frame, a conveying device, a limiting baffle, a hole aligning plate, a lifting screw rod, a first motor, a flange stacking and storing frame, a second lifting screw rod and a second motor, wherein the limiting baffle is not higher than the flange; the hole aligning plate is slidably arranged on the hole aligning frame; the lifting screw rod is arranged inside the hole aligning frame and is used for driving the hole aligning plate to slide downwards; the first motor isarranged inside the hole aligning frame and is used for driving the lifting screw rod to rotate; the hole aligning plate is connected with a disc-like rotating plate by virtue of a first thrust bearing; the rotating plate is fixedly connected with at least one pair of sleeves; the top wall of each sleeve is fixedly connected with a spring; each spring is fixedly connected with one hole aligning column which can slide inside the corresponding sleeve; each hole aligning column is rotationally connected with an idler wheel; the diameter of each hole aligning column is smaller than that of the corresponding idler wheel; the diameter of each sleeve is smaller than the hole diameter of each mounting hole in the wind power flange; the flange stacking and storing frame is used for stacking flangeplates; and the second lifting screw rod is used for driving the stacked flange plates to slide up and down. By using the automation device disclosed by the invention, manual operations for aligning the mounting holes before a plurality of flanges are hoisted are reduced, the labor intensity of a worker is alleviated, relatively high efficiency is achieved, and extremely good safety is realized.

Description

technical field [0001] The invention relates to an automatic device before hoisting of a wind power main shaft flange. 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 then the wind power flan...
