Digital model of brake plinth of mine hoist with rubber cable pulling equipment

Modernization of mine hoists by means of replacement of steel cable traction by rubber cable pulling equipment ensures increased capacity, decreased metal intensity and extended life of traction mechanisms. However, this engineering solution involves the change in the parameters of the main assemblies of mine hoists. For this reason, substantiation of designs of these assemblies is the actual basic and applied problem. The authors have reviewed the current mine hoist studies which appear to lack any investigation connected with braking systems for mine hoists with rubber cable pulling equipment. In this connection, toward the safe operation of mine hoists being modernized, it is proposed to discuss possible engineering decisions on braking systems. By estimates, the disc braking systems feature the highest efficiency. For the analysis of the disc brake performance, the method of digital modeling in SolidWorks environment is put forward and used to construct a digital model of the critical component of the braking system—a brake plinth. This digital model simulates braking forces equivalent to actual operating conditions of mine hoists, which allows the stress and stain assessment in the brake plinth. The studies include a series of tests using the proposed digital model, with estimation of maximum stresses versus design variables of the plinth in different operating conditions.
