Irigi yokumba phansi, kungenzeka ukuthi awukaze uzwe ngalolu hlobo lwemishini, akunjalo? Kuwuhlobo lomshini wokumba, ovame ukusetshenziselwa ukumba izimbobo zehange lamadwala, izimbobo zehange, izimbobo eziqhumayo, izimbobo zokubhoboza kanye nezinye izakhiwo zokumba ekwakhiweni kwamadolobha, ujantshi, umgwaqo omkhulu, umfula, ugesi wamanzi kanye neminye imiklamo. Kulesi sihloko, i-Xiaodian izokunikeza isingeniso esiningiliziwe ngesakhiwo, isimiso sokusebenza kanye nokuhlukaniswa kwama-rigs okumba phansi emgodini. asibone!
Ukwakhiwa kwe-Mechanism yendawo enkulu yokumba engaphansi komgodi.
1. Isitendi sokubhoboza: Isitendi sokubhoboza siyisitimela esiqondisayo sokushelela kwesisetshenziswa sokugwaza, ukuthuthukiswa nokuphakanyiswa kwethuluzi lokumba.
2. Ikhompathimenti: Inqola iyisakhiwo sebhokisi lesikwele esishiselwe amapuleti ensimbi, asetshenziselwa ukuxhuma nokusekela uhlaka lokubhola.
3. Idivayisi ejikelezayo: Lo mshini wakhiwe nge-hydraulic motor, indlela yokuphotha, ikhanda lokucindezela, ipuleti lama-slide kanye nendlela yokuphakelwa komoya emaphakathi. Iketango le-propulsion mechanism ligxilile kupuleti lesilayidi ngokusebenzisa iphinikhodi kanye nendlela yokuthambisa yasentwasahlobo.
4. I-Propulsion mechanism: I-propulsion mechanism yenziwe nge-propulsion hydraulic motor, isethi ye-sprocket, iketango kanye nesiphethu sebhafa.
5. Isithululi senduku: Isithululi senduku sakhiwe ngomzimba wenduku engenhla, umzimba wenduku engezansi, isilinda esicindezelayo nesilinda esikhipha induku.
6. Ithuluzi lokususa uthuli: Ithuluzi lokususa uthuli lihlukaniswe ngezindlela eziningana ezifana nokususa uthuli olomile, ukususwa kothuli olumanzi, ukususwa kothuli oluxubile kanye nokukhipha uthuli lwegwebu.
7. Indlela yokuhamba: Ithuluzi lokuhamba lakhiwe uhlaka lokuhamba, i-hydraulic motor, i-multi-stage planetary reducer, ibhande lokukhasa, isondo lokushayela, isondo eliqhutshwayo, kanye nomshini ocindezelayo.
8. Uhlaka: iyunithi ye-compressor yomoya, idivayisi yokususa uthuli, iyunithi yepompo yethangi likaphethiloli, iqembu lama-valve, ikhebhu, njll. konke kufakwe ohlakeni.
9. I-Fuselage slewing mechanism: Lo mshini wakhiwe nge-slewing motor, ibhuleki, i-deceleration device, i-pinion, i-slewing bear nokunye.
10. I-yaw mechanism ye-drilling rig: lo mshini wakhiwe nge-yaw cylinder, i-hinge shaft kanye nesihlalo se-hinge, engenza i-rig yaw kwesokunxele nakwesokudla futhi ilungise i-engeli yokubhoboza.
11. Isistimu ye-Compressor kanye ne- impactor: Isistimu ye-compressor ngokuvamile ifakwe i-screw air compressor ukuze inikeze umoya ocindezelekile wesistimu yokuhlanza i-jet ye-high-pressure impactor kanye ne-laminar flow dust collector.
Ukwakhiwa okuyisisekelo kwerigi yokumba inhloso evamile
Amathuluzi okubhoboza akhiwe ngepayipi lokubhoboza, ibhathini lenkinobho kanye ne- impactor. Lapho umba, sebenzisa ama-adaptha amapayipi okubhoboza amabili ukuze ubhoboze ipuleti lensimbi engagqwali. I-Rotary air supply mechanism iqukethe injini ejikelezayo, i-rotary reducer, kanye nedivayisi ezungezayo ehambisa umoya. I-slewing reducer iyingxenye evaliwe yobulili obuhlukile yegiya le-cylindrical elinezigaba ezintathu, eligcotshwa ngokuzenzakalelayo i-spiral oiler. I-air supply rotary device iqukethe umzimba oxhumayo, uphawu, i-shaft engenalutho kanye nejoyinti lepayipi lokubhoboza. Ifakwe izinsimbi zomoya zokuxhuma nokukhipha ipayipi lokubhoboza, i-Photinia. Umshini wokulungisa umfutho ophakamisayo uphakanyiswa yi-motor ephakamisayo ngosizo lwe-reducer ephakamisayo, iketanga lokuphakamisa, indlela yokubulala kanye nethuluzi lokubhoboza. Kuhlelo lwamaketanga avaliwe, kufakwa isilinda esilawula ukucindezela, i-pulley block ehambayo kanye ne-ejenti engangeni manzi. Lapho isebenza ngokujwayelekile, i-piston rod yesilinda esilawula ukucindezela iphusha ibhulokhi ye-pulley ukuze yenze ithuluzi lokumba libone ukubhoboza ukucindezelwa.
Isimiso sokusebenza se-down-the-hole rig yokumba
Umgomo wokusebenza we-rig yokumba imbobo ephansi uyafana naleyo yomthelela ojwayelekile wokubhoboza idwala le-rotary pneumatic. Ukubhoboza amatshe omoya kuhlanganisa indlela yokujula komthelela, futhi kudlulisele umthelela ku-drill bit ngokusebenzisa induku yokubhoboza; kuyilapho umshini wokumba ongaphansi komgodi uhlukanisa indlela yokuthinta (impactor) bese ungena ngaphansi kwembobo. Kungakhathaliseki ukuthi i-drill ijule kangakanani, i-drill bit ifakwe ngokuqondile ku-impactor, futhi amandla omthelela awadluliswa ngepayipi lokubhoboza, okunciphisa ukulahleka kwamandla okuthinta.
Ngokukhula kokujula kokumba komshini wokumba imbobo ephansi kanye nomshini wokumba amatshe, ukulahleka kwamandla okumba amatshe okubhoboza izinduku namajoyinti (imbobo emaphakathi, ukumba imbobo ejulile), njll. isivinini sokubhoboza siyancipha kakhulu, futhi izindleko ziyancipha. Ukuze kuncishiswe ukulahlekelwa kokukhiqiza, kuthuthukiswe ukusebenza kahle Kokubhoboza, umshini wokumba ongaphansi komgodi uklanywe ngobunjiniyela bangempela. I-rig yokumba imbobo ephansi iphinde inikwe amandla ngomoya ocindezelweyo, futhi isimiso sayo sokusebenza siwukuthi i-pneumatic impactor ye-down-the-hole drill ifakwe ekugcineni kwepayipi lokubhoboza kanye ne-drill bit. Lapho ubhoboza, umshini wokubhoboza ugcina ithuluzi lokubhoboza liqhubekela phambili, lisebenzisa ingcindezi ethile ye-axial phansi embobeni, futhi lenza i-drill bit ithintane nedwala ngaphansi komgodi; Ngaphansi kwesenzo, i-piston ibuyisela futhi ithinte i-drill bit ukuze iqedele umthelela edwaleni. Umoya ocindezelwe ungena usuka emshinini wokubhoboza umoya futhi ufinyelele phansi embobeni ngenduku engenalutho, bese impushana yedwala ephukile ikhishwa esikhaleni sonyaka phakathi kwepayipi lokubhoboza kanye nodonga lwembobo ukuya ngaphandle kwembobo. Kuyabonakala ukuthi ingqikithi yokumba amatshe aphansi-umgodi inhlanganisela yezindlela ezimbili zokuchotshozwa kwamadwala, umthelela kanye nokuzungezisa. Ngaphansi kwesenzo sokucindezela kwe-axial, umthelela uphakathi futhi ukujikeleza kuyaqhubeka. Ngaphansi kwesenzo, idwala liphuka ngokuqhubekayo futhi ligundwe. phoqa futhi phuca amandla. Ekubholeni amatshe aphansi-i-hole, amandla omthelela adlala indima ehamba phambili.
Ukuhlukaniswa kwemishini yokumba phansi emgodini
Isakhiwo se-down-the-hole rig yokumba ihlukaniswe ngezinhlobo ezimbili: uhlobo olubalulekile kanye nohlobo lokuhlukanisa. Ngokwendlela yokukhipha, ihlukaniswe yaba izinhlobo ezimbili: i-side exhaust kanye ne-centre exhaust. Ihlukaniswe ngokuma kwe-carbide ehlanganisiwe endaweni yokusebenza yomshini wokumba umgodi ophansi. Kukhona ukubhoboza i-DTH yeblade, izimbobo ze-DTH zezinyo lekholomu kanye ne-DTH eyingxube ye-blade-to-blade drill.
I-integrated down-the-hole drilling rig iyinsimbi yokubhoboza enomzimba owodwa eya phansi ngembobo eyenziwe ngekhanda nomsila. Kulula ukusetshenzwa futhi kulula ukuyisebenzisa, okunganciphisa ukulahleka kokudluliswa kwamandla. Okubi ukuthi lapho ubuso obusebenzayo bomshini wokumba umgodi ophansi bonakalisiwe, buzolahlwa ngokuphelele. Imodeli yokubhoboza i-rig ihlukaniswe nomsila (umsila wokubhoboza) we-down-the-hole rig rig, futhi lezi zimbili zixhunywe ngezintambo ezikhethekile. Uma inhloko ye-down-the-hole rig ilimele, umsila wokubhoboza usengagcinwa ukonga insimbi. Kodwa-ke, isakhiwo siyinkimbinkimbi, futhi ukusebenza kahle kokudluliselwa kwamandla kuyancipha.
