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: A shock-absorbing and energy-collecting roller cage shoe including a base, a main energy-collecting module, two auxiliary energy-collecting modules, and a roller is provided. The base is provided with three containing spaces for containing the main energy-collecting module and the two auxiliary energy-collecting modules. In the three containing spaces, the main energy-collecting module and the two auxiliary energy-collecting modules are respectively connected fixedly to the base through wire rope shock absorbers, the main energy-collecting module and the two auxiliary energy-collecting modules are respectively pressed on the left side, the upper side and the lower side of the roller, and the right side of the roller is pressed on a cage guide. The energy-collecting modules collect vibrational energy generated by vibration in the operation process of a lifting container, and convert the vibrational energy into collectable piezoelectric energy. The piezoelectric energy can be used to supply electric energy to electricity-consuming installations, such as such as the illumination of the lifting container, and thereby the collection and utilization of energy are realized.
