| description | The relevance of the work is determined by the need to increase the efficiency of hydraulic excavators, on which the cost of mining significantly depends. The purpose of the work is to improve the working equipment of a hydraulic excavator and develop a methodology for determining rational parameters that ensure a reduction in its weight. A scheme of working equipment is proposed with the exception of hydraulic cylinders for turning the boom in comparison with the traditional scheme and with a pressure mechanism with a pressure rod located on the superstructure on the axis of rotation. This scheme makes it possible to increase the capacity of the bucket and thereby the productivity of the excavator. A method for determining the design parameters of an excavator is presented, which ensures that the sections of the boom and arm are determined without “excessive” safety margins and thereby obtaining a minimum mass. At the same time, if you leave the tipping moment the same as that of the base model, then it will be possible to increase the capacity of the bucket and the productivity of the excavator. The EG-110 hydraulic excavator was taken as the base object used for comparison with the proposed design. The research results show the possibility of reducing the weight of working equipment by 5 tons and increasing productivity by 6%. |
