[7] a carriage that is movably and movably disposed in the inner space of the spiral track, the car having at least one opening corresponding to the passage of the side of the spiral track;

[8] A lifting drive mainframe includes a power unit and a rotating unit, the power unit is coupled to the vehicle, and includes an electric motor, a transmission shaft, and a transmission component connected between the electric motor and the transmission shaft, The rotary unit includes a rotating base and a spiral guide rotatably disposed in the inner space of the spiral track and assembled to the drive shaft, the spiral guide including at least one spiral guide and a plurality of Rolling members, the at least one spiral guide plate is fixed on the outer peripheral surface of the rotating base, corresponding to the spiral path formed by the spiral tracks, and the rolling elements are distributed on the bottom surface of the spiral guide plate to abut the On the spiral track.

[9] The present invention discloses a rotary elevator, and the features and effects of the present invention are compared to the prior art power pulley winding steel cable elevator: From the foregoing description, the rotary elevator designed by the present invention is mainly The driven rotary unit drives the vertical movement of the carriage along the spiral path formed by the spiral guides according to the spiral guides. Therefore, if the rotary elevator fails to operate normally during operation, the The carriage will rotate along the spiral path by the spiral guide, and the frictional resistance between the spiral guide and the spiral track will slow down the descending speed, so that the car does not fall immediately vertically downward, so that the invention has excellent In the previous power pulley winding steel cable elevator suspension to drive the safety of the car lift.
