Abstract
In the Republic of Belarus, on the base of JSC “Soligorsk Institute for Resources Saving Problems with Pilot Production”, the development and launch of import-substituting mass production of large-capacity double-drum mine winders with an increased diameter of winding drums up to 7 meters were fulfilled. Earlier, in the post-Soviet space, machines with similar technical characteristics were not produced. Accordingly, for the implementation of the project, a comprehensive study of all the scientific and technical aspects of the creation of this equipment was required, taking into account the material and technical capabilities of the enterprises of domestic mining engineering. One of the important results of this study was the development of an improved methodology for calculating the basic elements of a winder. The technique allows calculating the strength parameters of the winding drums, shaft, disengagement mechanism, drive elements (mating clutch), bearings together with their anchor fasteners, reduced to normal operating conditions and to conditions of emergency wire breakage. The methodology includes the calculation of the stress-strain state of the elements of the winding drums using the finite element method and allows using the obtained numerical data to simulate the stress-strain state of the main components of the hoisting machine to calculate its safety factors in normal operation and in emergency conditions. The developed methodology was successfully tested in the design and technological center of JSC “Soligorsk Institute for Resources Saving Problems with Pilot Production” during the development of double-drum mine winders with large diameter winding drums for skip hoisting units of the Petrikov mining and processing complex, as well as during the modernization of existing hoisting units at working mines of JSC “Belaruskali”.
