Kaishan KT30 Integrated Surface DTH Drilling Rig — Njira Yaikulu Kwambiri Yopangira Migodi

Kaishan KT30 ikuyimira luso laukadaulo wobowola wa Shaanxi Kaishan. Behemoth iyi ya matani 33.9 yapangidwa kuti ilamulire migodi yayikulu yotseguka komwe kupanga kwakukulu ndiko kokhako komwe kuli kofunika. Pakati pa injini yake pali injini yayikulu ya Cummins QSM15, yomwe imapereka mphamvu ya 563kW kuyendetsa compressor ya screw ya magawo awiri yokhala ndi mphamvu ya 39 m³/min pa 25 bar. Mphamvu ya mpweya imeneyi imalola KT30 kuyendetsa ma hammer a K8 pamabowo mpaka 254mm, zomwe zimapangitsa kuti ikhale imodzi mwa zida zolumikizidwa bwino kwambiri pamsika.

Chinthu chachikulu chomwe chikugwiritsidwa ntchito ndi KT30 ndikugwiritsa ntchito njira yoyendetsera njanji ya aluminiyamu pamodzi ndi mphamvu yayitali yobowola ya ndodo ya mamita 9. Pogwiritsa ntchito ndodo za mamita 9 (Φ140), chidachi chimachepetsa kwambiri kuchuluka kwa kusintha kwa ndodo, komwe ndi vuto lalikulu pakubowola mabowo akuya. Izi zimapangitsa kuti "nthawi yobowola yochuluka" ikhale yokwera pakusintha kulikonse. Njanji ya aluminiyamu imatsimikizira kuti ngakhale kutalika kumeneku, chakudya chimakhala chowongoka bwino, kuletsa kupotoka kwa mabowo ndikuwonetsetsa kuti mawonekedwe ophulika ndi olondola.

Makina oyendetsera ndi kulamulira mu KT30 ndi amagetsi okha. Makina oyendetsera ndodo okhazikika okha amagwira chitsulo cholemera cha mamita 9 molondola, pomwe makina oyandama olumikizirana ndi makina ojambulira mafuta okhazikika amateteza ndalama zanu mu zingwe zobowola zazikulu. Chogwirirachi chilinso ndi makina apamwamba oletsa kumamatira a electro-hydraulic omwe amayang'anira momwe kubowola kumachitikira nthawi yeniyeni, ndikubwezeretsa madzi ochulukirapo ngati kuuma kwa miyala kwasintha mosayembekezereka, kuteteza kuikidwa m'manda kokwera mtengo.

Kukhazikika ndi kusamalira malo ndikwabwino kwambiri pa makina olemera chonchi. KT30 ili ndi chassis yolemera yoyenda pansi yokhala ndi 430mm ya malo otseguka pansi komanso ma motor amphamvu okoka. Makina a boom ndi beam amapereka kusinthasintha kwakukulu kwa rig ya kukula kotere, yokhala ndi beam yopendekera ya 132° ndi stroke yolipirira ya 1800mm. Izi zimathandiza kuti rig iyike mwachangu komanso mosamala pa mipando yosagwirizana pamalo omwe akugwira ntchito mgodi.

Siteshoni ya woyendetsa galimoto pa KT30 yapangidwa kuti ikhale yotonthoza kwa nthawi yayitali komanso yowongolera zonse. Kabati yovomerezeka ya ROPS/FOPS ili ndi malo ogwirira ntchito okwanira, yokhala ndi mpweya woziziritsa, ndipo imapereka mawonekedwe owoneka bwino a malo ogwirira ntchito. Mkati mwake, woyendetsa galimotoyo ali ndi mwayi wowona ngodya ndi kuzama kwa malo ogwirira ntchito nthawi yeniyeni, zomwe zimathandiza kuti dongosolo lobowola lizigwira ntchito molondola. Ndi phokoso lomwe likuyendetsedwa bwino komanso dongosolo lowongolera lamagetsi lokhazikika, KT30 imalola ogwira ntchito kuyang'ana kwambiri pakupanga migodi yayikulu kwambiri padziko lonse lapansi.
