The invention relates to a crane stall self-locking device which comprises a rack, supporting plates are symmetrically and fixedly arranged at the top of the rack, a winding roller is rotationally arranged between the two supporting plates, the two ends of the winding roller are rotationally connected with the inner sides of the two supporting plates through rotating shafts correspondingly, and a steel cable is wound around the outer surface of the winding roller; a first brake assembly for driving the rotating shaft to stop rotating is arranged in the winding roller, a second brake assembly for driving the rotating shaft to stop rotating is arranged on one supporting plate, and a conversion assembly for converting kinetic energy into electric energy is arranged on the other supporting plate. The problems that in the prior art, although self-locking can be achieved for the stall of the crane, a rotating shaft suddenly stops rotating at the high rotating speed of the stall in the self-locking process, a steel cable is suddenly tightened under the strong inertia effect of a heavy object, the steel cable is prone to breakage, the heavy object falls off and even casualties are caused, and the danger is high are solved.
本发明涉及一种起重机失速自锁装置,包括机架,所述机架的顶部对称固定设置有支撑板,两个支撑板之间转动设置有收卷辊,收卷辊的两端均通过转动轴分别与两个支撑板内侧转动连接,收卷辊的外表面缠绕有钢索,收卷辊的内部设置有驱动转动轴停止转动的第一制动组件,其中一个支撑板上设置有驱动转动轴停止转动的第二制动组件,其中一个支撑板上设置有将动能转化成电能的转换组件;解决了现有技术中,虽然可以实现对起重机失速进行自锁,但是该自锁过程会使转轴在失速的高转速下突然停止转动,导致钢索在重物的强大惯性作用下突然紧绷,容易使钢索发生断裂,造成重物掉落甚至人员伤亡,危险性较高等问题。
