I-Kaishan KT30 Integrated Surface DTH Drilling Rig — I-Large-Scale Mining Rig Ephakeme Kakhulu

I-Kaishan KT30 imelela ubuchwepheshe bokubhoboza obuhlanganisiwe beShaanxi Kaishan. Le njini enkulu engamathani angu-33.9 yakhelwe ukubusa izimayini ezinkulu ezivulekile lapho ukukhiqizwa okuphezulu kuyiyona kuphela indlela ebalulekile. Enhliziyweni yayo kukhona injini enkulu yeCummins QSM15, enikeza amandla angu-563kW ukushayela i-screw compressor enezigaba ezimbili enomphumela ongu-39 m³/min ku-25 bar. Lo mthamo womoya uvumela i-KT30 ukuthi inike amandla izando ze-K8 zemigodi efinyelela ku-254mm, okwenza ibe ngenye yemishini ehlanganisiwe enamandla kakhulu emakethe.

Ubuchwepheshe obusha be-KT30 ukusebenzisa kwayo uhlelo lwesitimela oluqondisa i-aluminium oluhlanganiswe nomthamo wenduku yokubhoboza ende yamamitha ayi-9. Ngokusebenzisa izinduku zamamitha ayi-9 (Φ140), i-rig inciphisa kakhulu imvamisa yokushintsha kwezinduku, okuyisithiyo esikhulu ekubhobozeni imigodi ejulile. Lokhu kuholela "esikhathini esiphezulu sokubhoboza" ngokushintshwa ngakunye. Isitimela se-aluminium siqinisekisa ukuthi ngisho nangale mizuzu, ukudla kuhlala kuqondile ngokuphelele, kuvimbela ukuphambuka kwemigodi futhi kuqinisekise ubuqotho bephethini yokuqhuma.

Ukuzenzakalela nokulawula ku-KT30 ku-elekthronikhi ngokugcwele. Uhlelo lokuphatha induku oluzenzakalelayo luphatha insimbi esindayo engamamitha ayi-9 ngokunemba, kuyilapho izinhlelo zokujoyinta ezintantayo kanye nezinhlelo zokujova uwoyela ezizenzakalelayo zivikela ukutshalwa kwezimali kwakho ezintanjeni zokubhoboza ezinobubanzi obukhulu. Le rig iphinde ibe nohlelo oluthuthukisiwe lwe-electro-hydraulic anti-sticking oluqapha izimo zokubhoboza ngesikhathi sangempela, lubuyisela ngokuzenzakalelayo ukuphakelwa uma ubulukhuni bedwala bushintsha ngokungalindelekile, luvimbele ukungcwatshwa kwezinsimbi ezibizayo.

Ukuzinza kanye nokuphathwa kwendawo kuyingqayizivele emshinini onalesi sisindo. I-KT30 ine-chassis yokudonsa enamandla ene-430mm ye-ground clearance kanye nama-traction motor anamandla. Izinhlelo ze-boom kanye ne-beam zinikeza ukuguquguquka okumangalisayo kwe-rig yalesi sayizi, ene-tilt engu-132° beam kanye ne-stroke yokubuyisela engu-1800mm. Lokhu kuvumela i-rig ukuthi imiswe ngokushesha nangokuphephile emabhentshini angalingani endaweni yezimayini esebenzayo.

Isiteshi somqhubi ku-KT30 senzelwe induduzo yesikhathi eside kanye nokulawula okuphelele. I-cab eqinisekisiwe ye-ROPS/FOPS ivalwe ngokuphelele, inomoya opholile, futhi inikeza ukubonakala okubanzi kwendawo yokusebenza. Ngaphakathi, umqhubi unokufinyelela ekhoneni langempela kanye nesibonisi sokujula, okuvumela ukwenziwa okunembile kohlelo lokubhoboza. Njengoba amazinga omsindo egcinwa elawulwa kanye nokuhlelwa kokulawula kwe-elekthronikhi okuhlelekile, i-KT30 ivumela onjiniyela ukuthi bagxile ekukhuliseni ukukhiqizwa kwezimayini ezinkulu kakhulu emhlabeni.
