The invention discloses a lifting driving device and an elevator. A gear rotates in one rotating direction and is locked in the sinking direction of a platform by utilizing the function of a pawl structure; when the pawl needs to rotate in the rotation direction of the other pawl lock, the pawl can be rotated through the driving end to enable the head end of the pawl not to make contact with the inner gear ring of the gear, so that rotation of the gear is achieved, and when the driving end returns to the original position and does not interfere with the pawl any more, the pawl returns to the original position and can still lock the gear. Therefore, when the lifting platform ascends or descends, the locking function is provided at any height in the ascending process or the descending process, and the phenomenon that the lifting driving device settles in the air is avoided.
本发明公开了一种升降驱动装置及提升机,利用棘爪结构本身的功能使齿轮在一个转动方向上转动而在平台下沉方向上锁止;而需要在另一个棘爪锁止的转动方向上转动时,则可以通过驱动端将棘爪转动使棘爪的头端与齿轮内齿圈不接触,从而实现齿轮的转动,而驱动端归位不再干涉棘爪时,则棘爪也归位仍然可对齿轮锁止。从而在实现升降平台上升或下降的同时,在上升过程或下降过程的任一高度提供锁止功能,解决了升降驱动装置在空中出现沉降的现象。
