Unified method of calculation of traction organs of rope rollers and belt conveyors

Abstract

The existing method of calculating the traction body of mine rope pullers is similar to the method of calculating the rope of mine hoisting installations, developed by A. P. Herman. The method consists in determining the weight of a linear meter of rope by the maximum static load on the rope, including also its own weight, and in the selection of rope according to factory data on the basis of the weight found. The currently used method of calculating the traction organ of belt conveyors consists in the preliminary determination of power on the shaft of the drive drum conveyor, for which is tentatively taken the weight of moving parts of the conveyor, then sequentially determined: the traction force, the maximum tension of the belt, the required number of pads and, finally, the weight of a linear meter of belt. After the approximate weight of the belt is determined, the final calculation is repeated. With the current calculation methodology, the weight of the moving parts of the conveyor must inevitably be taken tentatively, since the exact weight of the belt is not known at the beginning of the calculation.
