I-Kaishan KG420B Surface DTH Drilling Rig — Ukuzinza Okuthuthukisiwe kanye Nokusebenza Okune-Torque Ephakeme

I-Kaishan KG420B iyithuluzi lokubhoboza i-DTH elisebenza kahle kakhulu, elihlukanisiwe elenzelwe izidingo ezisindayo zemisebenzi yokumba amatshe kanye nokumba. Iqukethe ithrekhi ekhethekile yohlaka olugoqekayo kanye nenjini enamandla ye-Yuchai 4-cylinder, le thuluzi lakhiwe ukuze linikeze ukuzinza okumangalisayo ezindaweni ezinde kanye nendawo engalingani. Kuyisinqumo esifanele sabasebenzi abadinga umshini onokwethenjelwa, one-torque ephezulu okwazi ukubhoboza imigodi emikhulu ngaphansi kwezimo ze-geological eziyinselele.

Lo modeli uwukuthuthukiswa okuphawulekayo ochungechungeni lwe-KG420, olulungiselelwe ngqo ukuhambisana nezindinganiso zokukhishwa kwedizili ngenkathi lukhulisa amandla omshini jikelele. Injini ye-Yuchai YC4DK80-T302 inikeza amandla aqinile angu-58KW, enikeza isisekelo se-torque ejikelezayo nesivinini esithuthukisiwe se-rig. I-Shaanxi Kaishan iklame le rig ukuze iphathe ububanzi bemigodi kusukela ku-90mm kuya ku-130mm, okwenza ibe ngelinye lama-rig aguquguqukayo kakhulu ekilasini layo.

Isici esivelele somshini we-KG420B ithrekhi yohlaka olugoqekayo oluhlanganiswe nokulinganisa ithrekhi (±10°). Lokhu kuvumela i-rig ukuthi igcine isikhungo esiphansi samandla adonsela phansi kanye nokubamba okuhle kakhulu ngisho nalapho ikhuphuka imithambeka engama-degree angu-30. Ukusetshenziswa kwe-plunger walking motor kuqinisekisa ukuqhutshwa kwe-torque ephezulu, kuyilapho uhlelo lokushayela olunamasondo amane luhlinzeka ngokubamba okudingekayo kwezitezi ze-quarry eziqinile. Indlu yephrofayili ejiyile kanye nezindandatho zokuphakamisa ezihlanganisiwe zengeza ungqimba lokuqina kwezinga lezimboni kanye nokuthuthwa kalula.

Ukusebenza kokubhoboza kuthuthukiswe kakhulu ngokusebenzisa isilinda sokuphakamisa esikhulu kanye nochungechunge lwamaqabunga oluqinisiwe. Lokhu kuthuthukiswa kuhumushela ekubeni amandla okuphakamisa angu-25KN kanye nokushaya okuphakelayo okungu-3780mm, okuqinisekisa ukuphathwa kwesando okuthembekile kanye nokuphathwa kwenduku. Njengoba ine-torque ephezulu ejikelezayo engu-2000N·m futhi ijubane layo lifinyelela ku-140rpm, i-KG420B ingasebenzisa amandla ngempumelelo edwaleni eliqinile (f=6-20) isebenzisa izando ezingu-3″ noma ezingu-4″.

Uhlelo lwe-boom kanye ne-beam lwe-rig lunikeza ukuguquguquka okumangalisayo. Njengoba i-beam tilt iyonke ingu-185° kanye nebanga lokujika elingu-145°, abaqhubi bangafinyelela ezindaweni zokubhoboza eziyinkimbinkimbi kalula. Isici sokubuyisela esingu-900mm siqinisekisa ukuthi i-guide rail ihlala ixhumene nomhlabathi ngokuqinile, kunciphisa ukudlidliza futhi kuthuthukiswe ukunemba kwemigodi. Imigodi evundlile ingabhobozwa ezindaweni eziphakeme ezisukela ku-350mm kuya ku-2750mm.

Ukuze kube nokusebenza kahle kokubhoboza, sincoma ukuhlanganisa i-KG420B nama-compressor ezikulufo ze-Kaishan ezicindezela kakhulu njenge-KSCY550-13, KSCY570/12-550/15, noma i-LGCY17/18-18/15T. Le rig ifaneleka kahle kakhulu ekumbeni okuvulekile okuphakathi nendawo kuya kokukhulu, ukwakhiwa kwemigwaqo, kanye namaphrojekthi ahlukahlukene engqalasizinda adinga ukubhoboza okujulile nokunembile kwe-DTH.
