The invention relates to the technical field of safety devices, and discloses a safety device for preventing an elevator from stalling and falling. The safety device for preventing the elevator from stalling and falling comprises a machine body, wherein a lift car is connected inside the machine body in a sliding mode, a first magnet is arranged inside a rotating cylinder, a fixed cylinder is connected to the inner side of the rotating cylinder in a rotating mode, a second magnet is arranged inside the fixed cylinder, a coil is arranged on the lower side of the second magnet, a solution chamber is arranged in the middle of the fixed cylinder, and an electric wire is fixedly connected to the left side of the coil. According to the safety device for preventing the elevator from stalling andfalling, the rotating cylinder rotates in an accelerated mode, then the first magnet and the second magnet move correspondingly, so that an induction magnetic field is generated; afterwards, the coilgenerates induction current, the current flows into current variant through the electric wire and an electric pole, the generated induction current is enough to enable the current variant to become solid, the motion of a moving pole is blocked, and the rotating cylinder is braked; and the structure achieves the effects of preventing safety accidents caused by stalling and protecting the elevator equipment.
本发明涉及保险装置技术领域,且公开了一种防止电梯失速下落的保险装置,包括机体,所述机体的内部滑动连接有客厢,转动筒的内部设置有第一磁铁,转动筒的内侧转动连接有固定筒,固定筒的内部设置有第二磁铁,第二磁铁的下侧设置有线圈,固定筒的中间位置设置有溶液室,线圈的左侧固定连接有电丝。该防止电梯失速下落的保险装置,通过转动筒加速转动,然后第一磁铁与第二磁铁发生相对应运动,从而产生感应磁场,然后线圈产生感应电流,电流通过电丝与电柱流入电流变体中,产生的感应电流足以将电流变体变成固体,使得运动杆运动受阻,从而制动转动筒,这一结构达到了防止失速造成安全事故发生和保护电梯设备的效果。
