A dual pass-through hoisting apparatus with a rotational locking mechanism, comprising an upper pass-through block (4) and a lower pass-through block (3) fixed to a hoisting hook, in which the two pass-through blocks comprise reversible connection means adapted to be reversibly configured between a connected configuration and a disconnected configuration, comprising a locking mechanism (5) and a complementary locking structure (6), the invention relates to a device (10) comprising at least one strike hole (65) and a bolt (52) which slidably moves and supports a locking finger (55) which is adapted to rotatably cooperate with the strike hole and to cooperate together with the respective guide element, thereby converting the relative approach and relative separation between the two penetrating blocks into a concomitant sliding and rotation of the bolt.
一种带有旋转锁定机构的双穿绕提升设备,包括上穿绕块(4)和固定到提升钩的下穿绕块(3),其中,两个穿绕块包括可逆连接装置,该可逆连接装置适于在连接配置与断开配置之间可逆地配置,其包括锁定机构(5)和互补锁定结构(6),分别包括至少一个撞击孔(65)和螺栓(52),该螺栓可滑动地移动并支撑锁定指状件(55),该锁定指状件适于与撞击孔可旋转地配合,并且相应的引导元件一起配合,从而将两个穿绕块之间的相对接近和相对远离转换成螺栓的伴随滑动和旋转。
