Ua hele waho ka rig wili wiliwili tona nui loa o ka honua ma Changsha, Hunan excavator roller roller

ʻO ka rig wili wili ʻona nui loa o ka honua i hoʻomohala kūʻokoʻa e Kina i hele i waho ma Changsha, Hunan.

Me ka hoʻokō ʻana i kekahi mau papahana ʻoihana nui o ka ʻāina, makemake nui ka mākeke i ka super rotary drilling rig me ka maikaʻi o ka puka ʻana o ka lua a me ka hana kiʻekiʻe.Eia nō naʻe, i kēia manawa, paʻakikī ka hoʻokō ʻana i nā pono hana o ka super large diameter deep hole rock socketed hole.Ma kēia pōʻaiapili i komo mai ai kēia "super rotary excavation" i being.excavator carrier roller
Mai Iulai 2020, ua hoʻomaka ka hui R&D e hoʻokō i ka hana R&D ma ka multi-functional rotary drilling rig.Ua mālama ʻo ia i 12 mau seminar loea loea a lanakila i nā pilikia ʻenehana he nui.Ua hoʻopau nā mea hana i ke kōmike kūloko o ka huahana mua i ka hopena o Dekemaba 2021 a e hāʻawi ʻia i ke kahua kūkulu ma hope o ka hōʻea ʻana i ke kūlana nānā.

Wahi a ka poʻe limahana R&D, hiki i kona anawaena drilling kiʻekiʻe ke piʻi i 7m a hiki i ka hohonu o ka wili ʻana ma mua o 170m, hiki ke hoʻokō i nā koi o ka super large diameter deep hole rock socketed pile, a hiki ke hoʻopili ʻia i ka hoʻokumu ʻana o ka hoʻokumu ʻana o nā papahana super. e like me nā alahaka ala moana.ʻO ke kaumaha o kēia mea hana e like me ka aneane 400 mau kaʻa, a ʻo kona kiʻekiʻe e like me 1280kn m.Hoʻonohonoho nā ʻāpana ʻenehana nui i kahi moʻolelo honua hou.

I mea e hoʻoponopono ai i ka pilikia paʻa i ke kaʻina hana o "super rotary excavation".Ua hoʻohana ka hui R&D i ka ʻenehana patented o "nui inertia rotary braking a me nā mea hoʻokele kaʻa kōkua" i nā mea hana e hōʻoia i ka paʻa o ka construction.excavator carrier roller
I ka manawa like, i mea e hoʻohana maikaʻi ai i ke kūkulu ʻia ʻana o ka pōhaku ultra deep and ultra large diameter, ua hoʻohana ka rotary drilling rig i nā ʻano kī like ʻelima mua o ka honua e hoʻoikaika i ka paipu drill nui.Ke hoʻohālikelike ʻia me ka paipu hoʻoheheʻe kī maʻamau ʻekolu, hiki iā ia ke hālāwai me ke kiʻekiʻe torque drilling a hoʻemi i ka ukana o ke kī hoʻokele.Ke hoʻohālikelike ʻia me ka paipu drill o ka lōʻihi like ma ka mākeke, hoʻonui ʻia ka hiki ke hoʻonui ʻia e 60%.

Eia kekahi, ʻaʻole "kaumaha" a "nui" wale ka rotary drilling rig, akā "naʻauao".Hoʻohana nā mea hana i ka ʻōnaehana electro-hydraulic control piha, hiki ke hoʻolako ʻia me ka mea hoʻokele mamao pōkole a me ka hale kūʻai hana mamao 5g e ʻike ai i ka hana unmanned a hōʻoia i ka palekana pilikino o nā limahana hana.
