I-Kaishan KG520 Surface DTH Drilling Rig — I-Heavy-Duty Motor-Chain Feed kunye ne-High Ground Clearance

I-Kaishan KG520 yisixhobo sokugrumba esinzima, esisebenza ngedizili esihlukeneyo se-DTH esenzelwe ukugrumba ngobubanzi obukhulu kwiindawo ezinzima kakhulu zokwemba umphezulu kunye neendawo zokumba imigodi. Imele inyathelo elibalulekileyo lokuphucula ubuchule, i-KG520 yenzelwe ukusingatha imingxunya emikhulu kunye neebhentshi ezinzulu ngelixa igcina ukuthembeka okudumileyo kweKaishan Group, umenzi wesithathu ngobukhulu kwihlabathi liphela wecompressor, eyaziwa ngayo kwihlabathi liphela. I-Shaanxi Kaishan ibonelela ngalo matshini njengesango lakho elisemthethweni lokufikelela kubuchule bobunjineli obuxhaswa yiKaishan eSeattle.

Enye yezona zinto zibalulekileyo zokuphucula kwi-KG520 kukutshintshela kwinkqubo yokutya ye-roller chain eqhutywa yi-motor. Ngokungafaniyo nee-cylinder feeds eziqhelekileyo, ulungiselelo lwe-motor-chain lubonelela ngamandla okuphakamisa kunye nokondla ahambelanayo kulo lonke ixesha lokubetha kwe-4150mm. Olu seto lunyusa kakhulu ukuthembeka kwe-rig ngexesha lokubhola umngxuma onzulu (Φ105-152mm) kwaye lunciphisa iimfuno zokugcinwa eziqhele ukunxulunyaniswa nee-hydraulic cylinders ezihamba ngesantya esiphezulu.

Ukukwazi ukulungelelanisa umhlaba lolunye uphawu lweKG520. Njengoko umhlaba uvulekile kangange-440mm—phantse uphindwe kabini kuneemodeli ezincinci—le rig inokunqumla phezu kwenkunkuma enkulu kunye nemiqobo ngaphandle kokonakalisa i-undercarriage yayo. Inkqubo yesakhelo esigoqekayo, esebenza ngeemoto ezine-torque ephezulu, ivumela umatshini we-6500KG ukuba uhambe ngesantya esifikelela kwi-4km/h kwaye woyise amanqanaba angama-30°, nto leyo eyenza ukuba ibe yenye yezona rig zishukumayo kakhulu kudidi lwayo lobunzima.

Amandla okubhola e-KG520 agxile kwi-injini ye-Yuchai YC4DK100-T304 esebenza kakuhle ekhupha i-73.5KW. La mandla aqhuba inkqubo ejikelezayo ekwaziyo ukuba ne-torque ye-4000N·m kwaye ikhawuleze ukuya kuthi ga kwi-100rpm. Idityaniswe ne-4150mm feed stroke, ethwala iintonga zokubhola ezinde (3m), i-KG520 inciphisa ixesha lokungasebenzi kweentonga kwaye yandisa ixesha "elincinci-ezantsi" lokudlala kakuhle imihla ngemihla.

Ukuze sisebenze ixesha elide, siye sayenza lukhuni indlu saza saqinisa ii-boom kunye nee-beam assemblies. Le rig ikwanonxibelelwano olukhulu lokuqokelelwa kothuli kunye nenkqubo eqinileyo yokulinganisa umkhondo we-±10° ukuqinisekisa ukulungelelaniswa ngokuchanekileyo kwemingxunya kwiibhentshi ezingalinganiyo. Ukufikelela okuphezulu okuthe tye kwandiswa ukuya kwi-3500mm, okubonelela ngendawo enkulu yokugrumba kwizicelo ezikhethekileyo ezifana nokugrumba ubuso kunye nokuqinisa ithambeka.

UShaanxi Kaishan ucebisa ukudibanisa i-KG520 nee-screw compressors eziphathwayo ezinoxinzelelo oluphezulu ezifana nothotho lwe-KSCY310/22 okanye i-LGCY19/21. Ezi yunithi zibonelela nge-15-22m³/min yomoya ofunekayo ukuze kuhlanjwe ngokufanelekileyo imingxunya emikhulu ye-Φ105-152mm kwaye kuqhutywe iihammer ze-DTH ezinefuthe eliphezulu ze-4″ okanye i-5″. Ukusukela oko yasekwa ngo-1956, iKaishan iye yaphucula ezi rig-compressor pairings ukuze inike ixabiso eliphantsi ngemitha kushishino.
