Also have as application number is 201310673410.8 and application number is 201320365185.7 new type spreader, and it all is to make full use of the installation hole of flange itself to lift, but all exists the work of the installation hole alignment before lifting, and this work is still by the worker Manual operation (using a large crane plus a spreader, supplemented by manual collaboration to align the mounting holes), is inefficient, and the cost of a large crane is high, the volume is large, and with the increase in labor costs, it increases production. cost, and because workers operate directly next to the flange, it is dangerous

Embodiment 1

[0038] Such as Figure 1 to Figure 6 as shown ( figure 1 The flange lifting device and the flange turning device are not shown; image 3 , Figure 4 Another bracket opposite to it is not shown), the present invention is a wind power main shaft flange lifting front rotation device that does not occupy the driving, including a frame 1, and a flange conveying device 2 is provided on the working surface of the frame 1, One end of the conveying direction of the frame 1 is provided with a lift-type limit baffle 3, and the height of the limit baffle 3 does not exceed the height of the flange; it also includes a flange lifting mechanism, which is arranged on two sides of the flange conveying device 2. side, and located below the flange, the flange lifting mechanism is provided with a rotary drive mechanism that drives the flange to rotate; it also includes a flange storage rack 15 with a flange storage platform 14, and a drive method is provided in the flange storage rack 15. The s...

Embodiment 2

[0040] The difference from Embodiment 1 is that, as Figure 7 As shown, the lifting lead screw and the drive motor are also arranged under the limit baffle, so that all operations are fully mechanized, without manual labor, and realize full automation.

Embodiment 3

[0042] The difference from Embodiment 1 is that, as Figure 8 As shown (flange lifting device and flange rotating device, limit pin, flange storage rack are not shown), the working surface of frame 1 is inclined, and the width of the conveying roller is less than the diameter of the flange.

Abstract

The invention discloses a rotating device used before hoisting of a wind power main shaft flange without occupying travelling crane. A rack is included; a flange conveying device is arranged on the work face of the rack; one end of the rack in the conveying direction is provided with a rising and falling type limiting baffle; a flange rising and falling mechanism is further included, and is arranged on the two sides of the flange conveying device and located below a flange; the flange lifting mechanism is provided with a rotating driving mechanism driving the flange to rotate; and a flange storing frame provided with a flange storing table is further included, and is internally provided with a lifting mechanism driving the flange storing table to rise and fall. By means of the rotating device used before hoisting of the wind power main shaft flange without occupying the travelling crane, manual operation for installing hole alignment before hoisting of flanges is reduced, the labor intensity of workers is relieved, efficiency is high, and safety is extremely good; and in the hole alignment process, the flanges do not make contact with the lower conveying device, and the service life of the lower conveying device is prolonged.

Description

technical field [0001] The invention relates to a wind power main shaft flange hoisting and rotating device which does not occupy a traveling vehicle. 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 equipme...
