The safety height limiting device for the hoisting machinery comprises a fixed seat, openings are formed in the top and the bottom of the fixed seat in a penetrating mode, supporting seats are fixedly arranged on the two sides of the bottom of the fixed seat, and a hoisting seat is arranged between the two supporting seats in a liftable mode; a hanging assembly used for hanging a heavy object is fixedly arranged at the bottom of the lifting seat, the hanging assembly can stably lift the heavy object, the heavy object is prevented from falling off in the lifting process, and a driving assembly used for lifting the lifting seat is fixedly arranged in the fixing seat. A positioning wheel for positioning the steel wire rope is also arranged between the driving assembly and the hoisting seat; the problems that in the prior art, although a hook can be limited, a steel wire rope is prone to knotting or uneven winding on a winding roller in the lifting and winding process of the steel wire rope, so that the steel wire rope is loosened suddenly in the lifting process, and a heavy object shakes are solved.

    本发明涉及一种起重机械安全高度限位装置,包括固定座,所述固定座的顶部和底部均贯穿设有开口,所述固定座的底部两侧均固定设置有支撑座,两个所述支撑座之间可升降地设置有起吊座,所述起吊座的底部固定设置有对重物进行悬挂的悬挂组件,所述悬挂组件可对重物进行稳定起吊,避免重物在起吊过程中发生掉落,所述固定座内部固定设置有对起吊座进行起吊的驱动组件,驱动组件与起吊座之间还设置有对钢丝绳进行定位的定位轮;解决了现有技术中,虽然可以实现钩子的限位,但是在钢绳起吊收卷过程中,钢丝绳很容易在收卷辊上产生打结或者缠绕不均匀的情况,导致起吊过程中钢绳会突然松开导致重物产生晃动等问题。
