The invention discloses a hoisting lifting pulley multiplying power rapid adjusting device, and relates to the technical field of hoisting loading and unloading machinery. The cantilever crane comprises a cantilever crane body, an upper pulley block is arranged on the top of the side wall of the cantilever crane body, a ratchet wheel dragging device is arranged on the upper portion of the side wall of the cantilever crane body, a swing fork is arranged on the side wall of the cantilever crane body and located below the ratchet wheel dragging device, and a double-pulley lifting hook and a single-pulley lifting hook are arranged below the cantilever crane body. Swing retaining rings are arranged between the double-pulley lifting hook and the single-pulley lifting hook and the boom body, and the double-pulley lifting hook and the single-pulley lifting hook are connected with the upper pulley block in a winding mode through the swing retaining rings. According to the invention, the tedious work of manually winding the steel wire rope and arranging the steel wire rope is avoided, the defect that time and labor are wasted during pulley multiplying power adjustment is overcome, the rapid adjustment of the pulley multiplying power of the hoisting steel wire rope is realized, the hoisting operation efficiency is improved, and the hoisting operation capability is expanded.

    本发明公开了一种起重升降滑轮倍率快速调整装置,涉及起重装卸机械技术领域;而本发明包括臂架本体,所述臂架本体的侧壁顶部设置有上部滑轮组,所述臂架本体的侧壁上部设置有棘轮拖曳器,所述臂架本体的侧壁且在棘轮拖曳器的下方设置有摆动叉,所述臂架本体的下方设置有双滑轮吊钩和单滑轮吊钩,所述双滑轮吊钩和单滑轮吊钩与臂架本体之间设置有摆动扣套,所述双滑轮吊钩和单滑轮吊钩通过摆动扣套与上部滑轮组缠绕连接;本发明,免除了繁琐的人工缠绕钢丝绳排绳工作,克服了滑轮倍率调整工作费时费力的弊端,实现了起重钢丝绳滑轮倍率的快速调整,提高了吊装作业效率和扩大了吊装作业能力。
