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

Kaishan KG520 ndi chida chobowola cha DTH cholemera, choyendetsedwa ndi dizilo, chomwe chimapangidwira kubowola m'mimba mwake m'malo ovuta kwambiri opangira migodi komanso miyala. Pokhala ndi luso lofunikira kwambiri, KG520 idapangidwa kuti igwire mabowo akuluakulu ndi mipando yozama pomwe ikusunga kudalirika komwe Kaishan Group, kampani yachitatu yayikulu padziko lonse lapansi yopanga compressor, imadziwika nako padziko lonse lapansi. Shaanxi Kaishan imapereka makinawa ngati njira yanu yovomerezeka yopezera luso laukadaulo la Kaishan ku Seattle.

Chimodzi mwa zinthu zofunika kwambiri pakusintha kwa KG520 ndi kusintha kwa makina odyetsera ma roller chain feed system. Mosiyana ndi ma cylinder feeds wamba, ma motor-chain configuration amapereka mphamvu yokweza ndi kudyetsa yokhazikika panthawi yonse ya 4150mm. Kukhazikitsa kumeneku kumawonjezera kwambiri kudalirika kwa rig panthawi yoboola mabowo akuya (Φ105-152mm) ndipo kumachepetsa zofunikira pakukonza zomwe nthawi zambiri zimagwirizanitsidwa ndi ma hydraulic cylinders okwera.

Kusinthasintha kwa malo ndi chizindikiro china cha KG520. Ndi malo otsetsereka a 440mm—pafupifupi kawiri kuposa ang'onoang'ono—chombochi chimatha kudutsa pa zinyalala zazikulu ndi zopinga popanda kuwononga pansi pa galimoto yake. Dongosolo la njira yokhotakhota, loyendetsedwa ndi ma mota amphamvu kwambiri, limalola makina a 6500KG kuyenda mpaka 4km/h ndikugonjetsa magiredi a 30°, zomwe zimapangitsa kuti ikhale imodzi mwa zida zoyenda kwambiri m'gulu lake lolemera.

Mphamvu yobowola ya KG520 imayang'ana kwambiri injini ya Yuchai YC4DK100-T304 yogwira ntchito bwino kwambiri yomwe imapereka mphamvu ya 73.5KW. Mphamvu imeneyi imayendetsa makina ozungulira omwe amatha kukhala ndi mphamvu ya 4000N·m ndipo imathamanga mpaka 100rpm. Pogwirizana ndi 4150mm feed stroke, yomwe imatha kusunga ndodo zazitali zobowola (3m), KG520 imachepetsa nthawi yopuma yosintha ndodo ndikuwonjezera nthawi ya "bit-on-bottom" kuti igwire bwino ntchito tsiku lililonse.

Kuti nyumbayo ikhale yayitali, takulitsa nyumbayo ndikulimbitsa ma boom ndi ma beam assemblies. Chidachi chilinso ndi mawonekedwe okulirapo osonkhanitsira fumbi komanso njira yolimba yoyezera njanji ya ±10° kuti zitsimikizire kuti mabowo ali bwino pamipando yosagwirizana. Kufikira kopingasa kwambiri kumakulitsidwa kufika pa 3500mm, zomwe zimapangitsa kuti pakhale envelopu yayikulu yobowola zinthu zina zapadera monga kubowola nkhope ndi kulimbitsa malo otsetsereka.

Shaanxi Kaishan akulangiza kuti agwirizanitse KG520 ndi ma compressor onyamula okhala ndi mphamvu yamphamvu monga KSCY310/22 kapena LGCY19/21. Mayunitsi awa amapereka mpweya wa 15-22m³/min wofunikira kuti atulutse bwino mabowo akuluakulu a Φ105-152mm ndikuyendetsa ma hammer a 4″ kapena 5″ DTH okhala ndi mphamvu yamphamvu. Kuyambira pomwe idakhazikitsidwa mu 1956, Kaishan yakonza ma rig-compressor awa kuti apereke mtengo wotsika kwambiri pa mita iliyonse mumakampani.
