Esona sixhobo sikhulu sokomba iitoni zehlabathi siphume ngaphandle kweintanethi eChangsha, iHunan excavator carrier roller

Esona sixhobo sikhulu ehlabathini sokomba iitoni ezijikelezayo ngokuzimeleyo ephuhliswe yi-China sahamba ngaphandle kweintanethi e-Changsha, eHunan.

Ngokuphunyezwa kwenani leeprojekthi zeziseko ezingundoqo zesizwe, imarike ngokukhawuleza ifuna i-super rotary drilling rig enomgangatho olungileyo wokwenza umngxuma kunye nokusebenza kakuhle kolwakhiwo. Nangona kunjalo, okwangoku, izixhobo zokwakha isiseko semfumba kunzima ukuhlangabezana neemfuno zomngxuma omkhulu onzulu welitye elinomngxuma owenziweyo. Kukule meko ke apho oku "super rotary kumbiwa" kuye kwaba.
Ukusukela ngoJulayi ka-2020, iqela le-R & D liqalise ukwenza umsebenzi we-R & D kwisixhobo sokubhola esijikelezayo esinemisebenzi emininzi. Ibambe ukuya kuthi ga kwiisemina zobugcisa ezili-12 kwaye yoyise ubunzima obuninzi bobugcisa. Isixhobo sigqibe ukugunyaziswa kwangaphakathi kwemveliso yokuqala ekupheleni kukaDisemba 2021 kwaye iya kuhanjiswa kwindawo yokwakha emva kokufikelela kumgangatho wokuhlola.

Ngokwabasebenzi be-R & D, ubukhulu bayo bokomba bunokufikelela kwi-7m kwaye ubunzulu bokomba bunokugqithisa i-170m, enokuthi ihlangabezane neemfuno zomngxuma omkhulu onzulu we-rock socketed, kwaye ingasetyenziswa kulwakhiwo lwesiseko semfumba yeeprojekthi ezinkulu ezifana neebhulorho zokuwela ulwandle. Ubunzima besi sixhobo bulingana neemoto eziphantse zibe ngama-400, kwaye i-torque yayo iphezulu njenge-1280kn m. Iiparamitha eziphambili zobugcisa zibeka irekhodi elitsha lehlabathi.

Ukuze kulungiswe ingxaki yokuzinza kwinkqubo yokwakhiwa "kwe-super rotary excavation". Iqela le-R & D lisebenzise iteknoloji enelungelo elilodwa lomenzi "i-inertia enkulu ye-rotary braking kunye nesixhobo esincedisayo sokuzinzisa imoto" kwisixhobo ukuqinisekisa ukuzinza kwe-construction.excavator carrier roller
Kwangaxeshanye, ukuze kufakwe ngcono ulwakhiwo lokungena lwamatye olunzulu kakhulu kunye nedayamitha enkulu, isixhobo sokomba esijikelezayo samkela uhlobo lwesitshixo esintlanu sokuqala sokungqamanisa ukuqinisa umbhobho wokubhola onobubanzi obukhulu. Xa kuthelekiswa nombhobho wokuqhuba ongundoqo ezintathu, inokuhlangabezana nokugrumba i-torque ephezulu kunye nokunciphisa umthwalo wesitshixo sokuqhuba. Xa kuthelekiswa nombhobho wokugaya ubude obufanayo kwimarike, umthamo wokuthwala unyuswe ngama-60%.

Ukongezelela, i-rotary drilling rig ayikho nje "inzima" kwaye "inkulu", kodwa "ihlakaniphile". Isixhobo samkela inkqubo yokulawula i-electro-hydraulic epheleleyo, enokuthi ixhotyiswe ngesilawuli esikude esifutshane kunye ne-5g ye-remote operation warehouse ukuqonda ukusebenza okungekho mntu kunye nokuqinisekisa ukhuseleko lomntu lwabasebenzi bokwakha.
