The invention relates to the technical field of elevators, and discloses a magnetic safety assembly for reducing gravitational potential energy during elevator stall falling. The magnetic safety assembly comprises a cable; a cable pipe is fixedly connected to the outer side of the cable; a speed reducing mechanism is movably connected to the outer side of the cable pipe; a gripper is movably connected to the top of the speed reducing mechanism; and a balance layer is fixedly connected to the inner side of the gripper. According to the magnetic safety assembly for reducing the gravitational potential energy during elevator stall falling, induced current is generated and transmitted to an electrode plate through transmission of a circuit, so that a coil on the outer side of the electrode plate is electrified, and when the gripper moves outwards, the speed reducing plate at the bottom of a connecting rod moves in the electrified coil; furthermore, in the moving process, according to the Lenz's law, it can be known that the speed reducing plate can generate the eddy current effect when the coil moves, and movement of the gripper is limited according to the coming and leaving refusing principle, so that the falling potential energy of the cable is consumed, and the elevator stall protection level is improved.
本发明涉及电梯技术领域,且公开了一种电梯失速坠落减少重力势能的磁力保险组件,包括缆线,所述缆线的外侧固定连接有缆线管,缆线管的外侧活动连接有减速机构,减速机构的顶部活动连接有抓手,抓手的内侧固定连接有平衡层。该电梯失速坠落减少重力势能的磁力保险组件,通过电路的传递,使产生感应电流,传递给电极板,从而使电极板外侧的线圈得电,从而当抓手向外侧运动时,从而使连杆底部的减速板,在得电线圈内部移动,进而在移动过程中根据楞次定律可知,使减速板在线圈运动时,会产生涡流效应,进而依据来拒去留的原则,使抓手的移动被限制,从而使缆线下落的势能被消耗,进而提高了电梯失速的保护等级。
