I-Kaishan KG420B Surface DTH Drilling Rig — Uzinzo oluPhambili kunye nokusebenza okunamandla aphezulu

I-Kaishan KG420B yirig yokugrumba ye-DTH esebenza kakuhle, ehluliweyo eyenzelwe iimfuno ezinzima zemisebenzi yokugrumba nokwemba. Inendlela ekhethekileyo yokugoba isakhelo kunye nenjini enamandla ye-Yuchai 4-cylinder, le rig yakhelwe ukubonelela ngozinzo olukhethekileyo kwiindawo ezithe tyaba kunye nomhlaba ongalinganiyo. Lukhetho olufanelekileyo kubasebenzi abafuna umatshini othembekileyo, one-torque ephezulu onokukwazi ukugrumba imingxunya emikhulu yobubanzi kwiimeko ezinzima zejoloji.

Le modeli iphucuke kakhulu kuthotho lwe-KG420, yenzelwe ngokukodwa ukuthobela imigangatho yokukhupha idizili ngelixa inyusa amandla oomatshini ngokubanzi. Injini yeYuchai YC4DK80-T302 inika i-58KW eqinileyo, inika isiseko se-torque ejikelezayo ephuculweyo kunye nesantya. UShaanxi Kaishan uyila le rig ukuze iphathe ububanzi bemingxuma ukusuka kwi-90mm ukuya kwi-130mm, nto leyo eyenza ukuba ibe yenye yezona rig zisebenziseka lula kudidi lwayo.

Uphawu olubalaseleyo lwe-KG420B yindlela egoqekayo yesakhelo kunye nokulinganisa umkhondo (±10°). Oku kuvumela isixhobo ukuba sigcine umbindi ophantsi womxhuzulane kunye nokutsala okugqwesileyo nokuba sinyuka ii-30-degree slopes. Ukusetyenziswa kwe-plunger walking motor kuqinisekisa ukuqhutywa kwe-torque ephezulu, ngelixa inkqubo yokuqhuba enamavili amane ibonelela ngokubamba okufunekayo kwimigangatho ye-quarry erhabaxa. Indlu etyebileyo kunye neeringi zokuphakamisa ezidityanisiweyo zongeza umaleko wokuqina kunye nokuthuthwa komgangatho weshishini.

Ukusebenza kokubhoboza kuphuculwe kakhulu ngokusebenzisa isilinda sokuphakamisa esikhulu kunye nekhonkco lamagqabi eliqinisiweyo. Olu phuculo luguqulela ekubeni ngamandla okuphakamisa angama-25KN kunye nokubetha kokutya okungama-3780mm, okuqinisekisa ukuphathwa kwehammer okuthembekileyo kunye nolawulo lwentonga. Ngomthamo ophezulu ojikelezayo we-2000N·m kwaye isantya sifikelela kwi-140rpm, i-KG420B inokusebenzisa amandla ngokufanelekileyo kwilitye eliqinileyo (f=6-20) isebenzisa iihammer ze-3″ okanye ze-4″.

Inkqubo ye-boom kunye ne-beam ye-rig inika ukuguquguquka okumangalisayo. Ngokuthambekela kwe-beam okupheleleyo kwe-185° kunye nobubanzi bokujika kwe-145°, abaqhubi banokufikelela kwiindawo ezinzima zokubhola ngokulula. Isici sokuhlawula i-900mm siqinisekisa ukuba ireyile yesikhokelo ihlala inxibelelene nomhlaba ngokuqinileyo, inciphisa ukungcangcazela kwaye iphucula ukuchaneka kwemingxuma. Imingxunya ethe tye inokubhobozwa kubude obuphakathi kwe-350mm ukuya kwi-2750mm.

Ukuze kube nokusebenza kakuhle kokubhola, sicebisa ukudibanisa i-KG420B nee-compressor ze-Kaishan ezine-high-pressure screw ezifana ne-KSCY550-13, KSCY570/12-550/15, okanye i-LGCY17/18-18/15T. Le rig ifanelekile kakhulu kwimigodi evulekileyo ephakathi ukuya kwenkulu, ukwakhiwa kweendlela, kunye neeprojekthi ezahlukeneyo zeziseko ezingundoqo ezifuna ukubhola okunzulu nokuchanekileyo kwe-DTH.
