XY series vertical shaft core drill is the main type of our country’s small-caliber ore prospecting construction， among which the XY-6 vertical shaft drill with large market can meet the needs of solid mineral exploration within 2000m， it is difficult to support a new round of prospecting breakthrough because of its disadvantages such as mechanical transmission， manual operation of belt-making and lack of drilling data， so it is urgent to upgrade XY series mechanical vertical shaft drilling rig. This paper mainly introduces the upgrading of the XY-6 vertical shaft drilling rig based on its frequency conversion electric drive and digital control， the XY-6DB new electric drive vertical shaft drilling rig has carried on the frequency conversion transformation of the rotary power unit， the electro-hydraulic control upgrade of the hoisting brake system， the manual-self-integrated shift mode and the digital control upgrade transformation of the whole rig， finally， the whole machine can realize the goal of saving energy， increasing efficiency， reducing labor intensity and improving safety.
