The invention relates to a hoisting mechanism suitable for a manhole cover at the cylinder wall of a vertical reaction vessel, the hoisting mechanism comprises a support, a rotating arm, a sliding assembly and a lifting hook assembly, the support comprises a first base plate, a first cover plate, a second cover plate and a first rib plate, and the rotating arm comprises an I-shaped supporting beam, a steel pipe fitting and a second rib plate. The steel pipe piece of the rotating arm is connected with the first cover plate and the second cover plate of the support through rotating connecting pieces so that the rotating arm can rotate relative to the support, and the sliding assembly comprises a first end plate, a second end plate, a double-end stud arranged between the first end plate and the second end plate and at least two sets of pulley assemblies. Each pulley assembly comprises a first wheel shaft, a second wheel shaft, a first pulley and a second pulley, the axis of the first wheel shaft and the axis of the second wheel shaft are located on the same straight line, the first pulley and the second pulley are both supported on the I-shaped supporting beam and can slide back and forth along the I-shaped supporting beam, the double-end stud is sleeved with the lifting hook assembly, and the safety performance is greatly improved.

    本发明涉及一种适用于立式反应容器筒壁处人孔盖的吊装机构,包括:支座、转臂、滑行组件及吊钩组件,所述支座包括:第一垫板、第一盖板、第二盖板及第一筋板,所述转臂包括:工型支撑梁、钢管件及第二筋板,所述转臂的钢管件与支座的第一盖板及第二盖板之间通过转动连接件连接从而使转臂可相对于支座转动,所述滑行组件包括:第一端板、第二端板及设置于第一端板与第二端板之间的双头螺柱及至少两组滑轮组件,每组滑轮组件包括第一轮轴、第二轮轴、第一滑轮及第二滑轮,第一轮轴与第二轮轴的轴心线位于同一条直线上,第一滑轮及第二滑轮均支撑于工型支撑梁上并可沿工型支撑梁作来回滑动,吊钩组件套设于双头螺柱上,大大提高了安全性能。
