I-Kaishan KG420TH Surface DTH Drilling Rig — Ingqokelela yothuli esebenza kakuhle kakhulu ukuze isebenze kakuhle

I-Kaishan KG420TH yisixhobo sokugrumba i-DTH esisebenza kakuhle, esisebenza ngedizili, esenzelwe abaqhubi ababeka phambili ukuthobela indalo ngaphandle kokulahla amandla okugrumba. Ngokusekelwe kwiqonga le-KG420T eliqinisekisiweyo, igama elithi "H" libonisa ukuhlanganiswa kwenkqubo yokuqokelelwa kothuli olunzima. Njengomsasazi osemthethweni weKaishan Group, uShaanxi Kaishan ukukuzisela umatshini oxhaswa phantse yiminyaka engamashumi asixhenxe yelifa lemizi-mveliso kunye nobunjineli obukumgangatho wehlabathi.

Umahluko oyintloko we-KG420TH yi-QZA-120 dust collector eqhelekileyo, enesihluzo se-12-filter esibamba ngokufanelekileyo amaqhekeza amancinci ngexesha lenkqubo yokubhola. Kwiindawo ezifuna ukuhluzwa okuphezulu nangakumbi okanye xa kubholwa imingxuma engaphezulu kwe-130mm, kukho i-QZA-140 collector enokukhetha kuyo enezihluzo ezili-16. Le nkqubo ayiqinisekisi nje kuphela imeko-bume esempilweni kubasebenzi kodwa ikwakhusela izinto zangaphakathi ze-rig kuthuli olurhabaxa, nto leyo eyandisa ubomi benkonzo yenjini kunye neenkqubo ze-hydraulic.

Ukuze kuqwalaselwe iimfuno zamandla ezongezelelweyo zenkqubo yokuqokelela uthuli, i-KG420TH ixhotyiswe ngenjini ye-Yuchai YC4DK100-T304 ephuculweyo. Ivelisa i-73.5KW kwi-2200rpm, le njini inika indawo efunekayo yokusebenza zombini ii-hydraulics zoxinzelelo oluphezulu kunye ne-dust vacuum ngaxeshanye, iqinisekisa ukuba amazinga okungena ahlala engaguquki nokuba kumatye anzima (f=6-20).

Ngokwesakhiwo, i-rig ine-housing etyebileyo kunye nenkqubo yesakhelo sokugoba esomeleleyo. Ukufakwa kwe-motor yokuhamba ene-torque ephezulu kunye ne-setup ye-4-wheel drive kuvumela umatshini we-5350KG ukuba uhambe kwiindawo ezirhabaxa kwaye unyuke amanqanaba ukuya kuthi ga kwi-30°. Inkqubo yokulinganisa i-track (±10°) iqinisekisa ukuba i-rig igcina indawo ethe nkqo okanye egobileyo kwimigangatho ye-quarry engalinganiyo, nto leyo ibalulekileyo ekuchanekeni kwemingxunya.

Amandla okubhola ahlala ephezulu, ene-torque ejikelezayo ye-3500N·m kunye ne-3175mm feed stroke eqhutywa yi-heavy-duty oil cylinder kunye ne-roller chain mechanism. I-rig iphatha imingxunya ye-Φ90-152mm ngokulula, nto leyo eyenza ukuba ibe sisixhobo esiguquguqukayo sokuqhumisa ibhentshi kwimigodi nakwiziseko zesakhiwo ekwakheni. Uluhlu lokulungiswa kwe-beam kunye ne-boom luvumela ukuguquguquka okumangalisayo, kubandakanya ukubhola ngokuthe tye kwiindawo eziphakamileyo ezingaphantsi kwe-350mm.

UShaanxi Kaishan ucebisa ukudibanisa i-KG420TH kunye nee-KSCY okanye ii-LGCY series portable air compressors ukuqinisekisa ukunikezelwa komoya okuzinzileyo kwe-13-20m³/min. Olu dibaniso lubonelela ngamandla "okucoca nokutyumza" afunekayo kwimisebenzi ye-DTH esebenzayo. Ngolwazi lwehlabathi lwe-R&D lweKaishan, kuquka neziko lethu lobuchwephesha eliseSeattle, i-KG420TH imele incopho yetekhnoloji yokugrumba umphezulu yanamhlanje, enobuhlobo nendalo.
