The invention relates to an elevator rope unwinding device, an elevator and a method for adjusting the rope unwinding speed of the elevator rope unwinding device. The elevator rope unwinding device comprises a support, a rope winding disc, at least one induction piece and at least one traction magnet, and the rope winding disc is rotatably arranged on the support; the induction piece is fixedly connected with the rope winding disc, and the induction piece is a closed conductor; and the traction magnet is fixed on the bracket. Therefore, when the rope is unwound, damping of a rotating load can be generated through cooperation between the traction magnet and the induction key, so that the rotating speed of the rope winding disc can be reduced, the rope unwinding speed of the wound rope is prevented from being increased abnormally, the wound rope is prevented from sliding down in an accelerated mode due to the gravity of the wound rope or the rope winding disc is prevented from rotating out of control due to the too high rotating speed, and the stable rope unwinding function is achieved.

    本申请涉及一种电梯放绳器、电梯和调整电梯放绳器放绳速度的方法,本申请的电梯放绳器包括:支架、卷绳盘、至少一个感应件以及至少一个牵引磁体,卷绳盘能转动地设于支架上;感应件与卷绳盘固定连接,感应件为闭合导体;牵引磁体固定于支架上。故本申请在放绳时,可以通过牵引磁体和感应键之间的配合产生旋转载荷的阻尼,从而可以降低卷绳盘转动的速度,防止绕绳的放绳速度异常变大,避免绕绳因自身重力而加速下滑或卷绳盘因转速过快而旋转失控,实现平稳放绳的功能。
