The invention discloses a transformer tap changer maintenance hoisting tool which comprises a steel wire rope assembly, and the steel wire rope assembly comprises a fixed circular ring, an O-shaped buckle, an upper steel wire rope hanging ring, a steel wire rope, a lower steel wire rope hanging ring, an O-shaped buckle inner groove, a fixed circular ring inner buckle, a hanging ring inner buckle, a ball groove and a ball. A connecting circular ring assembly is movably installed at the top end of the fixing circular ring, a lifting hook assembly is movably installed at the top end of the connecting circular ring assembly, O-shaped buckles are movably installed at the bottom ends of the fixing circular rings, and upper steel wire rope lifting rings are movably installed at the bottom ends of the O-shaped buckles. Through cooperation of the O-shaped buckle inner groove, the fixed circular ring inner buckle and the lifting ring inner buckle, the shaking angle of the fixed circular ring and the upper steel wire rope lifting ring in the O-shaped buckle is reduced, then the shaking frequency and degree of the lifting plate are reduced, the shaking frequency possibly generated when the transformer is lifted is reduced, and the stability of the device is improved.

    本发明公开了一种变压器调压开关检修吊装工具,包括钢丝绳组件,所述钢丝绳组件包括固定圆环、○型扣、上钢丝绳吊环、钢丝绳、下钢丝绳吊环、○型扣内槽、固定圆环内扣、吊环内扣、滚珠凹槽、滚珠,所述固定圆环的顶端活动安装有连接圆环组件,所述连接圆环组件的顶端活动安装有吊钩组件,所述固定圆环的底端均活动安装有○型扣,所述○型扣的底端均活动安装有上钢丝绳吊环。本发明通过○型扣内槽和固定圆环内扣以及吊环内扣的配合,使固定圆环和上钢丝绳吊环在○型扣的内部晃动的角度减小,进而使吊板的晃动频率及程度减小,减少了变压器在吊起时可能产生的晃动频率,提高了装置的稳定性。
