- Abstract
This article discusses a completely new concept for the diagnostics of sheaves in rope hoisting equipment used in deep mining, where excavated material, consumables, and people are transported via shafts. Rope sheaves involve shafting, guide sheaves, and support rollers on which ropes reel in special grooves. Those grooves may be made directly in the material of the sheave rim or in a specially installed plastic liner. Those grooves are made in the appropriate dimensions. Any change to those dimensions is due to a number of phenomena that occur in life cycle processes and significantly affects the condition of ropes. Measurement of the geometrical parameters of rope grooves for diagnostic purposes provides information about the condition of the rope system and guidance on the appropriate corrective actions. This article presents a solution that permits continuous measurement of selected geometrical parameters of the grooves using a non-contact method of scanning sheave rims with a laser beam. The basic geometric parameters of grooves and sheave rims were defined. The system was shown to be useful in the determination of axial and radial run-out of rope sheaves.
