The invention provides a self-rotating hoisting mechanism for a tower crane and the tower crane. The hoisting mechanism comprises a hoisting piece, a rotating assembly and a cart which are sequentially arranged from bottom to top, wherein the cart is used for being mounted on a suspension arm and moving along the suspension arm; the rotating assembly comprises a driving part, a first horizontal frame and a second horizontal frame, the first horizontal frame and the second horizontal frame are sequentially arranged from bottom to top, the first horizontal frame is rotationally installed on the second horizontal frame, the fixed end of the driving part is installed on the second horizontal frame, and the power output end of the driving part is connected with the first horizontal frame. The second horizontal frame is connected with the cart through at least three groups of retractable first lifting ropes, the at least three groups of first lifting ropes are uniformly distributed on the edge of the second horizontal frame around the mass center of the second horizontal frame, and the first horizontal frame is connected with the lifting piece; when the driving part works, the second horizontal frame does not move, and the power output end of the driving part drives the first horizontal frame and the hoisting part to rotate together. Self-rotation of the hoisting piece is achieved, and alignment and connection of the hoisting piece and the cargo hoisting position are facilitated.

    本发明提供一种塔吊用自旋转起吊机构和塔吊,其中起吊机构包括由下至上依次排列的吊装件、旋转组件和用于安装在吊臂上并沿吊臂移动的大车;旋转组件包括驱动件和由下至上依次排列的第一水平架和第二水平架,第一水平架转动安装于第二水平架上,驱动件的固定端安装于第二水平架上,驱动件的动力输出端与第一水平架连接;第二水平架通过至少三组可收放的第一吊绳与大车连接,至少三组第一吊绳围绕第二水平架的质心均匀分布在第二水平架的边缘,第一水平架与吊装件连接;驱动件工作,第二水平架不动,驱动件的动力输出端带动第一水平架和吊装件一块转动。实现吊装件的自旋转,方便吊装件与货物吊装位置的对准和连接。
