The invention belongs to the technical field of prefabricated stair construction, and particularly relates to a prefabricated stair hoisting device which comprises a hoisting beam connected with a hoisting hook of a crane and a pre-buried hoisting ring pre-buried in a prefabricated stair and further comprises two hoisting and pulling mechanisms used for connecting the hoisting beam and the pre-buried hoisting ring. The hoisting mechanism comprises a steel wire rope, a winding roller and two symmetrically-arranged lifting mechanisms, each lifting mechanism comprises a moving seat, a movable pulley, a fixed pulley and a moving driving mechanism, the moving seat is connected with a first guide part for limiting the moving seat to move in the length direction of the hoisting beam, and the moving seat is connected with the moving driving mechanism for driving the moving seat to move; the rotary driving part B drives the winding roller to rotate, when the winding roller rotates, one end of the steel wire rope is shortened, the other end of the steel wire rope is lengthened, the stair step plane is in a horizontal state, the stair can be conveniently installed in place, the winding driving mechanism can be directly controlled to adjust the heights of the two ends of the stair, and hoisting is more efficient.
本发明属于预制楼梯施工技术领域,具体的说是一种预制楼梯吊装装置,与吊机的吊钩连接的吊装梁和预埋于预制楼梯上的预埋吊环,还包括两个吊拉机构,吊拉机构用于连接吊装梁和预埋吊环,吊拉机构包括钢丝绳、收卷辊和对称设置的两个提升机构,提升机构包括移动座、动滑轮、定滑轮和移动驱动机构,移动座连接限制其沿吊装梁长度方向移动的第一导向件,移动座连接驱动其移动的移动驱动机构;本发明通过B旋转驱动件带动收卷辊转动,收卷辊转动时对钢丝绳的一端进行收短,对钢丝绳的另一端进行放长,使楼梯踏步平面呈水平状态,便于楼梯的安装就位,可以直接控制收卷驱动机构来对楼梯的两端高度的调节,使得吊装更加高效。
