The traction type elevator safety braking device comprises a magnetic device mounting base, a supporting frame and braking arms, the magnetic device mounting base is mounted at the top of one side of the supporting frame, and the braking arms are mounted at the bottom of one side of the supporting frame through a rotating shaft; a first anode electromagnet is installed on the top of the inner wall of the magnetic device installation base, and a set of sliding grooves are formed in the inner wall of the magnetic device installation base. When the magnetic device body is powered off, the first anode electromagnet and the second anode electromagnet are powered on, and the first anode electromagnet is fixedly mounted on the inner wall of the magnetic device mounting seat through the effect that like poles repel, so that the repelling force can push the second anode electromagnet to move downwards; in the using process, the problem of metal fatigue caused by independent use of a spring can be avoided, and then the braking effect can be improved.

    本发明公开了一种曳引式电梯安全制动装置及其制动方法,包括磁力器安装座、支撑架和制动臂,所述支撑架一侧的顶部安装有磁力器安装座,所述支撑架的一侧的底部通过转轴安装有一组制动臂,所述磁力器安装座内壁的顶部安装有第一阳极电磁铁,所述磁力器安装座的内壁开设有一组滑槽。本发明通过在磁力器本体断电时,便会为第一阳极电磁铁和第二阳极电磁铁通电,通过同性相斥的效果,第一阳极电磁铁是固定安装在磁力器安装座的内壁,因此排斥的力能够推动第二阳极电磁铁向下移动,进而能够使第一制动瓦对制动轮进行制动,能够在使用过程中,避免单独使用弹簧,而出现金属疲劳的问题,进而有利于提高制动效果。
