Abstract
The present invention relates to a crystal lifting device which comprises a lifting assembly composed of a wire roller, a drag steel wire rope, a transmission shaft and an actuating unit, wherein the drag steel wire rope is wound around the wire roller, the transmission shaft is rotatablely supported on a supporting body and is connected by the same shaft with the wire roller, and the actuating unit drives the transmission shaft and the wire roller to rotate. A drag wheel and the wire roller are fixedly connected together and are together sheathed on the transmission shaft. The transmission shaft is connected with at least one of the drag steel wire wheel and the wire roller through a spline along the axial direction of the transmission shaft in a sliding mode. The drag sleeve is fixed to the supporting body, and the drag wheel is connected with the drag sleeve through screw threads. The screw pitch of the screw thread between the drag wheel and the drag sleeve determines that the axial displacement generated by rotating the drag wheel for one circle is equal to the axial displacement generated by the drag end of the steel wire rope, which corresponds to the wire roller in the reverse direction. The device of the present invention has the advantages that the horizontal servo of the wire roller is realized, the left and right positional stability of the steel wire rope is ensured, the speed stability and the centering performance of the steel wire during the lifting process are enhanced, and the service life is prolonged.
