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

Incazelo Yomkhiqizo

I-Kaishan KT7H Integrated Surface DTH Drilling Rig yakhelwe abaqhubi abadinga "imisipha" eyengeziwe emijikelezweni yabo yansuku zonke yokubhoboza. Yakhelwe ngqo ukumbiwa kwemigodi evulekile kanye nokumbiwa kwamatshe amakhulu, i-KT7H ikhulisa amandla kanye nomthamo uma kuqhathaniswa nezinye ezincane. Ngokugcina kokubili umthombo womoya ocindezelekile kanye ne-hydraulic rig ku-crawler eyodwa, eqinile, inikeza izinga lokuhamba okungenakukwazi ukulilinganisa nezilungiselelo zendabuko zamayunithi ahlukene.

Enhliziyweni ye-KT7H kukhona injini yedizili i-Yuchai YC6A260-T301, enikeza amandla amakhulu angu-191kW. Lawa mandla engeziwe abalulekile ekushayeleni i-compressor yezikulufo ezimbili ezihlanganisiwe, ekhipha i-17m³/min ku-18 bar. Lokhu kugeleza komoya kulungiselelwe ukususa izingcezu ezinkulu ezivela emigodini esukela ku-105mm kuya ku-146mm, okuqinisekisa ukuthi ngisho nasezindaweni ezijulile noma ezimanzi, intuthuko yakho yokubhoboza ihlala ifana futhi ishesha.

I-KT7H isebenzisa umsebe wokuqhuma we-aluminium alloy onamandla aphezulu, uphawu lochungechunge oluhlanganisiwe lwe-Kaishan. Lo mklamo wehlisa kakhulu isisindo esiku-boom ngenkathi ugcina ukuqina okudingekayo kokuphakelwa kokucindezela okuphezulu kanye nokujikeleza kwe-torque ephezulu. I-rig iphinde ibe nohlelo lokuphatha induku oluzenzakalelayo kanye ne-drill pipe lubrication module ezinikele, ehlanganisa ukunciphisa kakhulu isikhathi sokungasebenzi esihlotshaniswa nokushintsha induku futhi igcine isikhathi eside sentambo yakho yokubhoboza.

Ukusebenza ezindaweni ezinezintuli kudinga ukuhluzwa okuphezulu, kanti i-KT7H ihlinzeka ngohlelo lwayo lokuqoqa uthuli olomile olusebenza kahle kakhulu. Lokhu akugcini nje ngokugcina i-rig ihlanza—kunciphisa izikhawu zokulungisa—kodwa futhi kuqinisekisa ukuthi umqhubi usebenza endaweni ephephile necacile. I-boom eguquguqukayo kanye ne-beam geometry ye-rig (kufaka phakathi ukuthambekela okungu-147° kanye nokujikijela okungaphezu kuka-100°) kuvumela indawo eqondile ngisho nasendaweni engalingani noma ebhentshini.

Njengoba inendawo evulekile engu-430mm kanye nomthamo wokunyuka ongu-25 degrees, i-KT7H iyahamba njengoba inamandla. Iphatha ukushintshela phakathi kwezindawo zokumba kalula, isusa isidingo sethraktha ehlukile noma imoto yokudonsa. Isekelwa yi-R&D yomhlaba wonke kaKaishan kanye nokuzibophezela kukaShaanxi Kaishan ekusekelweni kwendawo, i-KT7H iwumsebenzi othembekile kunoma yimuphi umakhi wezimayini ozimisele.
