The invention discloses a hoisting mechanism of a tower crane, and belongs to the technical field of hoisting mechanisms. According to the key points of the technical scheme, the hoisting mechanism comprises a lifting hook and a sling, and the sling is connected with the end of the lifting hook; two mounting boxes which are of empty shell structures are tightly attached to and fixedly mounted on the inner side wall of the lifting hook, and a distance is reserved between the two mounting boxes; a first sliding block, a second sliding block and a third sliding block are arranged on each mountingbox slidably, and all the three sliding blocks are of a blocky structure with the cross section in a right trapezoid shape; both the first sliding blocks and the third sliding blocks are horizontallyand movably arranged on the side walls, close to each other, of the two mounting boxes in a penetrating mode, wherein the slope ends of the first sliding blocks are located at the exteriors of the mounting boxes; and the slope ends of the two first sliding blocks form a V-shaped groove structure, and the slope ends of the third sliding blocks are located in the mounting box. According to the hoisting mechanism of the tower crane, unhooking is not liable to occur, and the safety is high.

    本发明公开了一种塔式起重机的起吊机构,属于起吊机构技术领域,其技术方案要点是,包括吊钩和吊索,吊索连接在吊钩的端部,吊钩的内侧壁上紧贴并固定安装有两个均为空壳结构的安装盒,两个安装盒之间隔有距离,且每个安装盒上均滑动设置有第一滑块、第二滑块和第三滑块,三者均为横截面为直角梯形的块状结构,第一滑块和第三滑块均水平活动贯穿设置在两个安装盒相互靠近的侧壁上,其中第一滑块的斜面端位于安装盒的外部,两块第一滑块的斜面端形成V字型槽状结构,第三滑块的斜面端位于安装盒的内部。该种塔式起重机的起吊机构难以发生脱钩,安全性高。
