The invention relates to a large-tonnage high-lift double-winding-drum hoisting mechanism which comprises a driving assembly, a single-linkage double-layer winding drum set, a steel wire rope, a fixed pulley set, a balance pulley set and a hook pulley set. The single-linkage double-layer winding drum sets are coaxially arranged in a bilateral symmetry mode. The driving assemblies are correspondingly connected to the outer ends of the single-linkage double-layer winding drum sets respectively. The lifting hook pulley block is arranged below the space between the single-linkage double-layer winding drum groups on the two sides; the fixed pulley sets are correspondingly arranged in front of the inner ends of the single-linkage double-layer winding drum sets on the two sides respectively. The balance pulley blocks are correspondingly arranged in front of the outer ends of the fixed pulley blocks on the two sides respectively. An upper-layer steel wire rope and a lower-layer steel wire rope on the single-linkage double-layer winding drum group are simultaneously wound and unwound, the wound and unwound steel wire ropes are sequentially wound through a movable pulley and a fixed pulley block on a hook pulley block, and the tail ends of the steel wire ropes are hung and wound on a balance pulley. The lifting mechanism is high in reliability, simple in structure, large in lifting weight and stroke, small in occupied space and capable of achieving overall light weight.
本发明涉及一种大吨位高扬程双卷筒起升机构,包括驱动组件、单联双层缠绕卷筒组、钢丝绳、定滑轮组、平衡滑轮组和吊钩滑轮组;所述单联双层缠绕卷筒组呈左右对称同轴布置;所述驱动组件分别对应连接在单联双层缠绕卷筒组的外端部;所述吊钩滑轮组设置在两侧单联双层缠绕卷筒组之间的下方;所述定滑轮组分别对应设置在两侧单联双层缠绕卷筒组的内端前方;所述平衡滑轮组分别对应设置在两侧定滑轮组的外端前方;所述单联双层缠绕卷筒组上的上层钢丝绳和下层钢丝绳同时收放,收放的钢丝绳通过吊钩滑轮组上的动滑轮和定滑轮组依次缠绕,钢丝绳末端挂绕在平衡滑轮上。本发明可靠性高、构造简单,起升重量和行程大、占用空间小、能实现机构整体轻量化。
