The invention discloses electromagnetic driving type elevator safety tongs and an elevator car operation control method based on the electromagnetic driving type elevator safety tongs. The electromagnetic driving type elevator safety tongs comprise an electromagnetic lifting driving mechanism, a lifting seat, a clamping arm, an elastic supporting mechanism and a shell. The shell is fixed relative to the lift car, a lifting seat capable of lifting is installed in the shell, two clamping arms are installed on the lifting seat, an elevator shaft guide rail penetrates through the space between the two clamping arms, the two clamping arms are used for clamping the elevator shaft guide rail, and the bottoms of the clamping arms can rotate relative to the lifting seat; the two clamping arms are installed on the two elastic supporting mechanisms, each elastic supporting mechanism comprises a supporting block, a guide rod and a disc spring, the supporting blocks are fixed to the guide rods, and the guide rods penetrate through the shell. According to the electromagnetic drive type elevator safety tongs and the elevator car operation control method based on the electromagnetic drive type elevator safety tongs, the problem that in the prior art, the probability that the first safety tongs and the second safety tongs execute clamping actions at the same time is low is solved.

    本发明公开了一种电磁驱动式电梯安全钳及基于其的电梯轿厢运行控制方法,该电磁驱动式电梯安全钳包括:电磁提高驱动机构、升降座、夹持臂、弹性支撑机构以及外壳;外壳相对轿厢固定,外壳内安装有能升降的升降座,升降座上安装有两夹持臂,两夹持臂之间供电梯井导轨穿过,两夹持臂用于夹紧电梯井导轨,夹持臂底部能相对升降座旋转;两夹持臂安装在两弹性支撑机构,每一弹性支撑机构均包括:支撑块、导向杆以及碟簧,支撑块固定至导向杆,导向杆穿过外壳。该电磁驱动式电梯安全钳及基于其的电梯轿厢运行控制方法解决现有技术中第一安全钳和第二安全钳同时执行夹紧动作的概率较低的问题。
