The elevator car dragging device comprises a rack, the inner wall of the rack is rotationally connected with a rotating shaft driven by a motor, the end face of the rotating shaft is provided with a dragging wheel, the circumferential side face of the dragging wheel is in transmission connection with a set of steel cables, and a self-lubricating assembly is arranged in the dragging wheel; the circumferential side face of the rack is rotationally connected with two symmetrically-arranged guide frames, the rotating axes of the two guide frames and the axis of the rotating shaft are located on the same straight line, guide wheels attached to the steel cable are rotationally connected between the inner surfaces of the two guide frames, and the surface of the rack is slidably connected with a quick maintenance frame. According to the invention, when the dismounting or maintenance operation of the dragging wheel needs to be carried out, the two guide wheels are fully lifted under the driving action of the quick maintenance frame, and finally the height of the guide wheels is higher than that of the dragging wheel, so that the steel cable is separated from the dragging wheel, and after the steel cable is separated from the dragging wheel, the dragging wheel can be quickly replaced.

    本发明公开了一种电梯轿厢拽引装置及拽引方法,包括机架,机架的内壁转动连接有通过电机驱动的旋轴,旋轴的端面安装有拽引轮,拽引轮的周侧面传动连接有一组钢缆,拽引轮的内部设置有自润滑组件,机架的周侧面转动连接有两个对称设置的导引架,两个导引架的旋转轴线均与旋轴的轴线在同一直线上,两个导引架的内表面之间均转动连接有与钢缆贴合的导向轮,机架的表面滑动连接有快维架。本发明中,当需要进行拽引轮的拆卸或维护作业时,两个导向轮在快维架的驱动作用下充分举升,并最终使导向轮的高度高于拽引轮,继而使钢缆与拽引轮脱离接触,钢缆与拽引轮脱离接触后,继而可进行拽引轮的快速更换。
