I-Kaishan KT7H Integrated Surface DTH Drilling Rig — I-High-Performance Open-Pit Driller

Ingcaciso yeMveliso

I-Kaishan KT7H Integrated Surface DTH Drilling Rig yenzelwe abaqhubi abafuna "izihlunu" ezingakumbi kwimijikelo yabo yemihla ngemihla yokugrumba. Yenzelwe ngokukodwa ukwembiwa kwemigodi evulekileyo kunye nokugrumba amatye amakhulu, i-KT7H yonyusa amandla kunye nomthamo xa ithelekiswa nezinye ezincinci. Ngokugcina umthombo womoya oxinzelelweyo ophezulu kunye ne-hydraulic rig kwi-crawler enye, eqinileyo, ibonelela ngenqanaba lokuhamba elingenakukwazi ukulilinganisa nezicwangciso zemveli zeeyunithi ezahlukeneyo.

Intliziyo ye-KT7H yi-Yuchai YC6A260-T301 diesel engine, enika amandla amakhulu e-191kW. La mandla ongezelelweyo abalulekile ekuqhubeni i-compressor yezikrufu edibeneyo enezigaba ezimbini, ekhupha i-17m³/min kwi-18 bar. Olu hambo lomoya lulungiselelwe ukususa iziqwenga ezinkulu kwimingxuma ukusuka kwi-105mm ukuya kwi-146mm, ukuqinisekisa ukuba nokuba kukwiindawo ezinzulu okanye ezimanzi, inkqubela yakho yokumba ihlala ihambelana kwaye ikhawuleza.

I-KT7H isebenzisa umqadi wokutyhala we-aluminium alloy onamandla aphezulu, uphawu lothotho oludibeneyo lweKaishan. Olu yilo lunciphisa kakhulu ubunzima kwi-boom ngelixa lugcina ukuqina okufunekayo kwi-high-pressure feed kunye ne-high-torque rotation. I-rig ikwaqulathe inkqubo yokuphatha intonga ezenzekelayo kunye ne-drill pipe lubrication module ezinikeleyo, ezithi xa zidibene zinciphise kakhulu ixesha lokungasebenzi elinxulunyaniswa nokutshintsha iintonga kwaye zigcine ixesha elide lomtya wakho wokubhola.

Ukusebenza kwiindawo ezineenkqantosi ezinothuli kufuna ukuhluzwa okuphezulu, kwaye i-KT7H ibonelela ngenkqubo yayo yokuqokelelwa kothuli olomileyo esebenza kakuhle kakhulu. Oku akugcini nje ngokugcina i-rig icocekile—kunciphisa amaxesha okugcinwa—kodwa kukwaqinisekisa ukuba umqhubi usebenza kwindawo ekhuselekileyo necacileyo. I-boom eguquguqukayo ye-rig kunye ne-beam geometry (kuquka ukuthambeka kwe-147° kunye ne-swing engaphezulu kwe-100°) zivumela indawo echanekileyo nokuba kumhlaba ongalinganiyo okanye ojikelezileyo.

Njengoko inendawo evulekileyo engama-430mm kunye nomthamo wokunyuka ongama-25 degrees, i-KT7H iyakwazi ukuhambahamba kwaye inamandla. Iphatha utshintsho phakathi kweendawo zokumba ngokulula, isusa imfuneko yetrektara okanye isithuthi sokutsala esahlukileyo. Ixhaswa yi-R&D yehlabathi kaKaishan kunye nokuzibophelela kukaShaanxi Kaishan kwinkxaso yendawo, i-KT7H ngumsebenzi othembekileyo kuye nawuphi na umkontileka wemigodi ozimiseleyo.
