The invention belongs to the technical field of hoisting equipment, and particularly relates to a lifting hook for tower crane hoisting. The interior of the hollow disc is rotationally connected with a rotating wheel; a sling is arranged on the outer side of the rotating wheel; a mounting rack; a mounting block is fixedly connected to the bottom of the mounting frame; the top of the lifting hook penetrates through the mounting block and is rotationally connected with the mounting block; the fixing ring is fixedly connected to the upper side of the mounting block, and the top of the lifting hook is located in the fixing ring; a group of insertion holes are uniformly distributed in the circumference of the inner side of the fixing ring; a slide hole; a pair of bolts are slidably and hermetically connected into the two ends of the sliding hole; an elastic rope is fixedly connected between the bolt and the side wall of the sliding hole; the sliding holes are filled with air through the air inflation assembly, the air pushes the pair of plug pins to slide towards the two sides, then the plug pins are inserted into one plug hole, the lifting hook cannot rotate, goods cannot rotate in the air after the goods are lifted by a sling subsequently, and therefore the stability of the goods in the transferring process is improved, and potential safety hazards are reduced.

    本发明属于起重设备技术领域,具体的说是一种塔吊起重用吊钩,包括空心盘;所述空心盘内部转动连接有转轮;所述转轮外侧设置有吊索;安装架;所述安装架底部固接有安装块;吊钩,所述吊钩顶部贯穿安装块并与之转动连接;固定环,所述固定环固接于安装块上侧,且吊钩顶部位于固定环内部;所述固定环内侧圆周均布有一组插孔;滑孔;所述滑孔两端内部滑动密封连接有一对插销;所述插销与滑孔侧壁之间固接有弹性绳;通过充气组件向滑孔内部充入空气,空气推动一对插销向两侧滑动,进而插销插入其中一个插孔内部,使得吊钩无法转动,后续吊索将货物吊起后货物无法在空中转动,从而提高货物转运过程中的平稳性,降低安全隐患。
