The invention relates to the technical field of elevator slings, in particular to an elevator sling with a falling protection function. The elevator sling with the falling protection function comprises a rotating disc, integrally formed groove strips are arranged on the surface of the rotating disc, the intervals of the groove strips are the same, a sling main body is arranged inside the groove strips, and one end of the sling main body is fixed on the surface of the rotating disc. The elevator sling has the beneficial effects that the whole sling main body is wound around the surface of the rotating disc, and one end of the sling main body is fixed to the surface of the rotating disc, so that a rotating rod is driven to rotate through the effect of a gear motor, the whole rotating disc can be driven to rotate, the sling main body is retracted and released, and an external lift car elevator is moved up and down; and if the gear motor goes wrong, the whole elevator can fall rapidly, at the moment, through the effect of a rotation speed sensor, rapid increase of the rotation speed is detected, and a signal is immediately sent to a first electric telescopic rod and a second electric telescopic rod.

    本发明涉及电梯吊索技术领域,具体为一种带坠落保护功能的电梯吊索,带坠落保护功能的电梯吊索包括转动盘,转动盘的表面设置有一体成型的凹槽条,每个凹槽条的间距相同,凹槽条的内部设置有吊索主体,吊索主体的一端固定在转动盘的表面;有益效果:整个吊索主体是盘绕在转动盘的表面,并且吊索主体的一端固定在转动盘的表面,这样通过减速电机的作用,带动转动杆进行转动,即可带动整个转动盘进行转动,对吊索主体进行收放的作用,将外部的轿厢电梯进行上下移动,而若减速电机出现问题时,整个电梯会出现急速坠落的情况,而这时,通过转速传感器的作用,检测到转速急速上升,立即将信号发送至第一电动伸缩杆与第二电动伸缩杆。
