Head Svyeshnikov Igor Arkadijovych, Registration Date 18-01-2001 Organization V.Bakul Institute for Superhard Materials popup.description2 The object of researches - rock-breaking tool both cutting heads of mining machines and drilling rigs. The purpose of operation - mining both intrusion of constructions of a rock-breaking tool and cutting heads of a new technological level for heading machines heavy duty and modern boring machinery, including for anchor boring applied in a coal industry of Ukraine. Methods of studies - analytical and experimental definition of design parameters of a rock-breaking tool and regime arguments of breaking down of rock. The account of a rational location of chisels on a bit of a heading machine is carried out. Is designed the recommendations for designing cutting heads of heading machines. With the help of the designed program for РС the accounts of coordinates of tops of cutters are carried out at their rational location on a surface of a bit. The arrangement of chisels on a surface of a bit is carried out automatically on designed algorithm. The estimation of effectiveness of a location of chisels will be carried out by an evaluation of the summarized moment of forces of rotating operating on chisels, which one simultaneously are in contact to soil. On the basis of values dispersion of the indicated moment of rotating forces for different positions of a bit during cutting reliability of operation of a bit is valued. Thus the statistical model of the moment forces rotating dispersion is used. On the basis of designed model of operation of a bit and obtained numeric outcomes the recommendations concerning designing a cutting head of a heading machine are worked out. The requirement specification on prototype of a chisel for a blasthole drilling under anchor strengthening is designed. The experimental batch of a rock-breaking tool for a blasthole drilling under anchor strengthening and prototype of a cutting head of a heading machine manufactured. Range of application - rock-breaking tool for a coal industry. Product Description popup.authors popup.nrat_date 2020-04-03 Close
