Abstract: Systems and methods for detecting a layer-to-layer transition of a lifting steel wire rope on a reel are described. The system includes a reel assembly for winding a steel wire rope on a reel and a tensioning assembly for tensioning a segment of said steel wire rope. The system further includes a loading assembly and a lead screw sliding assembly. The loading assembly provides a vertical loading to the tensioning assembly so as to generate a loading force between the tensioned steel wire rope and the steel wire rope wound around the reel. The lead screw sliding assembly drives the tensioning assembly so as to move on a horizontal guide rail to generate a relative displacement between the tensioned steel wire rope and the steel wire rope wound around the reel. The tensioning assembly is connected to the loading assembly via a first threaded rod and a static torque sensor.

Abstract: The present invention relates to a horizontally movable vertical shaft rope guide and a regulating method thereof which are suitable for guiding of hoisting containers in vertical shafts. The vertical shaft rope guide comprises a hoisting rope, and two hoisting containers suspended from the tail ends of the hoisting rope, wherein, cage guide ropes are led through guide cage lugs arranged on the two sides respectively, a tensioner arranged on the ground at the shaft top is connected to the upper end of each cage guide rope, and a connector arranged under a steel slot at the shaft bottom is connected to the lower end of each cage guide rope; a hydraulic cylinder is connected at the other side of each tensioner and the corresponding connector, and the hydraulic cylinder is connected to the tensioner or connector. During hoisting in the vertical shaft, the hydraulic cylinders are controlled to act in advance, to push the tensioners or connectors to move towards the center between the two hoisting containers, so that the cage guide ropes led through the guide cage lugs on the two sides of the hoisting containers get close to each other at the same time and wrap the hoisting container; thus, the horizontal displacement of the hoisting containers is restrained, and the impact of air flow on the two hoisting containers is minimized when the two hoisting containers meet.
