The invention relates to an underwater ball valve ball core lifting hook which comprises a lifting hook body. The lifting cross rod is rotationally arranged at the bottom of the lifting hook main body; the driving mechanism is suitable for driving the hoisting cross rod to rotate; when the driving mechanism drives the hoisting cross rod to be in a vertical state, the hoisting cross rod is inserted into a balance hole in the top of the ball core; the driving mechanism drives the hoisting cross rod to be in a horizontal state to hoist the ball core; after the installation of the ball core is completed, the driving mechanism drives the hoisting cross rod to be in a vertical state, and the hoisting cross rod is pulled out from the balance hole to be separated from the ball core; the driving mechanism can drive the lifting cross rod to be in a horizontal state or a vertical state relative to the lifting hook column body; the hoisting cross rod in the vertical state can enter and exit from the ball core balance hole, and the hoisting cross rod in the horizontal state can hoist the ball core cross rod; in conclusion, the device can realize hoisting of the ball core and separation after hoisting.
本发明是水下球阀球芯吊钩,包括:吊钩主体;吊装横杆,其转动设置在吊钩主体底部;驱动机构,其适于驱动吊装横杆进行转动;当驱动机构驱动吊装横杆处于竖直状态时,吊装横杆插入球芯顶部的平衡孔内;驱动机构驱动吊装横杆处于水平状态,对球芯进行吊装;完成球芯的安装后,驱动机构驱动吊装横杆处于竖直状态,将吊装横杆从平衡孔处抽出与球芯分离;驱动机构能够驱动吊装横杆相对于吊钩柱体呈水平状态或竖直状态;竖直状态的吊装横杆能够实现从球芯平衡孔处的进出,处于水平状态的吊装横杆能够实现对球芯横杆的吊装;综上,本装置能够实现球芯的吊装与吊装后的分离。
