The invention relates to the field of machining and hoisting of large annular workpieces, in particular to an annular workpiece hoisting device and method. The gravity center position detection mechanism comprises a distance sensor arranged on the main body cross beam and a reflecting part arranged on the middle split of the workpiece, and is used for detecting the distance between the main body cross beam and the middle split of the workpiece and judging whether the lifting appliance is in the gravity center position of the workpiece or not; the automatic clamping mechanisms are arranged at the two ends of the main body cross beam respectively, each automatic clamping mechanism comprises a lifting hook, and the two lifting hooks can be driven by a first driving device to move in the same direction or opposite directions in the axis direction of the main body cross beam to clamp a workpiece; and the safety locking mechanism is arranged in the center of the main body cross beam and comprises a stop pin and a second driving device, and the second driving device drives the stop pin to move to a designated position in the radial direction of the workpiece, is clamped on the workpiece, reversely drives the whole hoisting device to move and finely adjusts the position of the hoisting device.
本发明涉及大型环形工件的机加工吊装领域,具体涉及一种环形工件吊装装置及方法,包括:吊装支撑机构,包括主体横梁;重心位置探测机构,包括设置在主体横梁的距离传感器以及设置在工件中分面上的反光件,用于检测主体横梁与工件中分面之间的距离,判定吊具是否在工件的重心位置;自动夹紧机构,分别设置在主体横梁的两端,每个自动夹紧机构包括一个吊钩,两个吊钩在第一驱动装置驱动下能沿着主体横梁的轴线方向相向或相反运动,夹紧工件;安全锁止机构,设置在主体横梁的中心位置,包括止动销和第二驱动装置,所述的第二驱动装置驱动止动销沿着工件径向方向移动至指定位置,并卡在工件上,反向带动整个吊装装置移动,对吊装装置位置进行微调。
