本发明公开了一种多轮驱动装置及驱动方法,本发明采用多个曳引轮分开布置,并利用多个曳引轮中间的位置放置曳引机定转子,使得曳引机的结构尺寸更小,结构更加合理,有利于电梯部件在有限的井道尺寸内合理布局,设有的阻尼限速盘以及强磁铁,当电梯为断电时出现急速下坠时,利用转盘上的金属块产生与转盘转动相反的作用力,进而降低转盘转动速度,减小电梯下降速度,设有的超速制动装置在电梯异常下降时,利用离心力使限位柱脱离转芯进入限位槽内,并通过限位挡迅速卡住限位柱,进而将转芯紧急制动住,进而将固定轴和转轴紧急制动住,使多个曳引轮停止转动,使电梯停止下降,大大提高了本发明对电梯的安全保障。

    The invention discloses a multi-wheel driving device and a driving method. According to the multi-wheel driving device and the driving method, a plurality of traction wheels which are arranged separately are adopted, and traction machine stator rotors are placed in the middle positions of the traction wheels, so that the structure size of the traction machine is smaller, the structure is more reasonable, and the reasonable layout of an elevator component in a limited hoistway size is facilitated; a damping speed limiting disc and a strong magnet are arranged, when an elevator is powered off, asharp drop occurs, a metal block on a rotating disc generates an acting force opposite to the rotation of the rotating disc, the rotating speed of the rotating disc is reduced, and the descending speed of the elevator is reduced; an arranged overspeed brake device enables a limiting column to be separated from a rotating core and enter a limiting groove under the effect of the centrifugal force when the elevator abnormally descends, and then the limiting column is quickly clamped through a limiting baffle, so that the rotating core is braked in emergency, then a fixed shaft and a rotating shaft are braked in emergency, the traction wheels stop rotating, the elevator stops descending, and the safety guarantee of the elevator is greatly improved.
