The invention relates to a device and method for driving an asynchronous door vane of an elevator, and relates to the technical field of elevator door motors. The device comprises door vane assembliesthat includes a left floating vane arm, a right floating vane arm, a bottom plate, an upper connecting rod, a lower connecting rod, a left vane arm, a right vane arm, a first connecting rod, a rockerand a locking hook hinged to the bottom plate, wherein the device also comprises a first rotating rod, a double swing lever stroke amplifying assembly and a locking mechanism for driving the left andright knife vane to close. The invention relates to a method for realizing the closing of the asynchronous door vane and a locking device providing driving force. The movement of the rocker in the process of closing the door vane is converted into an approximate linear movement in the direction of the center horizontal normal of the roller through the double swing lever stroke amplifying assembly, so that the door vane can be closed and the door ball of a hoistway door lock is clamped in a small stroke during the process of car door opening. Aiming at the integrated asynchronous door vane with the locking hook having the function of a door opening restriction device, the floating vane arms realize the lifting effect of the locking hook of an antitheft device under the reaction of the doorball of the hoistway door lock while the lifting of the locking hook of the hoistway door lock is realized.

    本发明涉及一种电梯异步门刀驱动装置及方法,涉及电梯门机的技术领域,其包括门刀组件,门刀组件包括左浮动刀臂,右浮动刀臂,底板,上连杆,下连杆,左刀臂,右刀臂,第一连杆,摇杆和铰接底板的锁钩;还包括第一转动杆、双摆杆行程放大组件以及为驱动左右刀臂闭合的闭锁机构。本发明涉及一种异步门刀闭合的实现方法及提供驱动力的闭锁装置,通过双摆杆行程放大组件把门刀闭合过程摇杆的运动转化为滚轮中心水平法线方向的近似直线运动,可以在轿门在开门过程小行程内实现门刀闭合且夹紧厅门锁门球,针对具有开门限制装置功能的锁钩的一体式异步门刀,浮动刀臂在厅门锁门球的反作用下,在实现厅门锁锁钩抬起的同时,实现防扒装置锁钩抬起的效果。
