I-Kaishan KG520 Surface DTH Drilling Rig — Ukudla Kwe-Heavy-Duty Motor-Chain kanye Nokususwa Okuphezulu Komhlaba

I-Kaishan KG520 iyithuluzi lokubhoboza i-DTH elisebenza ngodizili elinamandla amakhulu, elenzelwe ukubhoboza ngobubanzi obukhulu ezindaweni zokumba eziyinkimbinkimbi kakhulu kanye nokumba amatshe. Imele isinyathelo esibalulekile sokuthuthukiswa kwekhono, i-KG520 yenzelwe ukusingatha imigodi emikhulu kanye namabhentshi ajulile ngenkathi igcina ukuthembeka okudumile iKaishan Group, umkhiqizi wesithathu ngobukhulu emhlabeni we-compressor, eyaziwa ngakho emhlabeni jikelele. I-Shaanxi Kaishan inikeza lo mshini njengesango lakho elisemthethweni lokufinyelela ubuhle bobunjiniyela obusekelwa yiKaishan eSeattle.

Enye yezithuthukisi ezibaluleke kakhulu ku-KG520 ukushintshela ohlelweni lokuphakelwa kwe-roller chain oluqhutshwa yinjini. Ngokungafani nokuphakelwa kwe-cylinder okujwayelekile, ukucushwa kwe-motor-chain kunikeza amandla okuphakamisa nawokuphakelayo ahambisanayo kulo lonke uhlaselo lwe-4150mm. Lokhu kusetha kukhulisa kakhulu ukuthembeka kwe-rig ngesikhathi sokubhoboza imigodi ejulile (Φ105-152mm) futhi kunciphisa izidingo zokugcinwa ezivame ukuhlotshaniswa nama-cylinder e-hydraulic ahamba ngomjikelezo ophezulu.

Ukuzivumelanisa nezimo kwendawo kungenye impawu ye-KG520. Njengoba inendawo evulekile engu-440mm—cishe kabili kuneyamamodeli amancane—le rig ingadlula phezu kwemfucumfucu emikhulu nezithiyo ngaphandle kokulimala kwenqola yayo engaphansi. Uhlelo lwethrekhi yohlaka olugoqekayo, olusebenza ngama-motor ane-torque ephezulu, luvumela umshini ongu-6500KG ukuthi uhambe ngesivinini esifinyelela ku-4km/h futhi unqobe amazinga angu-30°, okwenza kube ngenye yama-rig ahambayo kakhulu esigabeni sayo sesisindo.

Amandla okubhoboza e-KG520 agxile enjinini ye-Yuchai YC4DK100-T304 esebenza kahle kakhulu enikeza amandla angu-73.5KW. Lawa mandla aqhuba uhlelo olujikelezayo olukwazi ukuba ne-torque engu-4000N·m futhi lusheshisa kufika ku-100rpm. Uma luhlanganiswe nomfutho wokuphakelwa ongu-4150mm, oluthwala izinduku zokubhoboza ezinde (3m), i-KG520 inciphisa isikhathi sokungasebenzi esishintshashintsha izinduku futhi yandisa isikhathi "sokubheka phansi" ukuze kuthathwe izithombe zansuku zonke.

Ukuze kube nokuhlala isikhathi eside kwesakhiwo, siqinise indlu futhi saqinisa i-boom kanye ne-beam assemblies. I-rig iphinde ibe ne-interface ekhulisiwe yokuqoqwa kothuli kanye nesistimu eqinile yokulinganisa ithrekhi ye-±10° ukuqinisekisa ukulingana okunembile kwemigodi emabhentshini angalingani. Ukufinyelela okuphezulu okuvundlile kunwetshwa ku-3500mm, okunikeza imvilophu enkulu yokubhoboza yezinhlelo zokusebenza ezikhethekile njengokubhoboza ubuso kanye nokuqinisa i-slope.

UShaanxi Kaishan uncoma ukuhlanganisa i-KG520 nama-compressor ezikulufo eziphathwayo ezinomfutho ophezulu njenge-KSCY310/22 noma uchungechunge lwe-LGCY19/21. Lawa mayunithi ahlinzeka ngevolumu yomoya engu-15-22m³/min edingekayo ukuze kuhlanzwe ngempumelelo imigodi emikhulu engu-Φ105-152mm futhi kushayelwe izando ze-DTH ezinethonya elikhulu ezingu-4″ noma ezingu-5″. Selokhu yasungulwa ngo-1956, i-Kaishan ithuthukise la ma-rig-compressor ukuze alethe izindleko eziphansi kakhulu ngemitha embonini.
