Uhlobo lokuCoca oluPhantsi
Ubume obuphambili kunye neempawu zokusebenza
- Ulwakhiwo oluphambili
- Isixhobo samkela i-crawler chassis, inkqubo yolwelo lwamanzi eyenziwe yinjini
kunye nempompo ye-hydraulic efakwe ngasemva kwesithuthi kukuqhuba isinciphisi se-motor ukuqhuba i-chassis ye-crawler, eqonda umsebenzi ozihambelayo.
2.Iijekhi ezine zehydraulic zifakwe ngaphambili nangasemva kwi-chassis yengoma. Umatshini oyintloko unokuxhaswa kwaye amanqanaba angaphambili, angasemva, asekhohlo nasekunene anokulungelelaniswa ngaphandle kokulinganisa umhlaba wendawo yokwakha. Iijacks zinokuvulwa kwaye zivaliwe ngokukhululekileyo phantsi kolawulo oluhlukeneyo. Ngethuba lokwakhiwa, iijekhi ze-hydraulic zandiswa, kwaye ububanzi obuninzi be-fulcrum ye-left and right outriggers inokufikelela kwi-3.8m.
3. I-gantry ye-drilling rig igxininiswe ekupheleni kweqonga le-chassis kwaye ibekwe ngokuthe nkqo (ilizwe lokusebenza).
4. Isakhelo se-gantry kunye nomnyango wokuvula umnyango kwinqanaba elisezantsi liyisakhiwo esidibeneyo, esiphucula kakhulu ukuzinza kwesakhiwo esipheleleyo sesakhelo.
5. I-subframe ye-gantry ifakwe ngaphakathi kwi-gantry, engagcini nje ukwandisa ukusebenza okukhokelayo, kodwa yenza ukuba ulwakhiwo luzinzile, kwaye lwandisa kakhulu ubomi benkonzo yombhobho we-drill. Intloko yamandla ifakwe ngaphakathi kwinqanaba elisezantsi le-gantry subframe. I-cylinder ye-hydraulic esetyenziselwa ukuphakamisa intloko yamandla (kubandakanywa ne-subframe) ifakwe kwi-tube yesikwere se-mullion ye-subframe.
6. Intloko ejikelezayo ithatha intloko ejikelezayo ye-rotary drilling rig, eyandisa i-torque yemveliso
iqhutywa ziimotor ezintathu ezingama-107 eziguquguqukayo
7. I-mullion echanekileyo ye-gantry ifakwe i-manipulator kunye ne-cantilever crane (eyakhiwe nge-hydraulic winch, i-cantilever, i-pulley, njl.). Isetyenziselwa ukukhupha kunye nokudibanisa imibhobho yokubhobhoza.
8. Ngokusondeleyo ngasemva kwe-gantry, i-middle and front part of the platform ixhotyiswe nge-cab, exhotywe nge-console yokusebenza, isikrini sokubonisa, i-air conditioner, njl.
9. Emva kwekhabhi kunye naphakathi kweqonga, ipompo ye-slurry ifakwe. Impompo eludaka iqhutywa ngqo yinjini engama-90kw. Ukulahlekelwa kwamandla ombane kunye nokuguqulwa kwe-hydraulic kuyaphetshwa. Kwangaxeshanye, iindleko zokwakha ziyancitshiswa.
10. Kwisikhululo sempompo se-hydraulic ngasemva kweqonga, kufakwe iinkqubo ezimbini ezizimeleyo ze-hydraulic:
10.1 Inkqubo ye-hydraulic yokuhamba yenziwe yi-Cummins 197kw injini ye-diesel kunye ne-negative flow flow variable impompo eguquguqukayo, esetyenziselwa i-motor yokuhamba, i-cylinder ye-injini ye-outrigger, i-cylinder yokuvula umnyango, i-cylinder yokuphakamisa kunye nezinye izinto ezisebenzayo. Kukulungele ukuhamba kwindawo yokwakha kunye nokulungelelanisa imingxuma yemfumba ye-drilling rig.
10.2 I-Rotary head hydraulic system yenziwe nge-132kw i-asynchronous motor yesigaba sesithathu kunye nokuhamba okungahambi kakuhle kwepompo eguquguqukayo yamandla, esetyenziselwa umsebenzi ojikelezayo wentloko, ukuphakamisa i-cylinder yeoli, i-cylinder yeoli ye-manipulator, i-winch ye-hydraulic kunye nezinye izinto ezisebenzayo.
Inkqubo ye-hydraulic ephezulu yenzelwe ngokukodwa ukujikelezwa kwempompo yokufunxa umva. Impompo ephambili, i-rotary head motor, ivalve ephambili, ivalve encedisayo yomthwalo kunye nezinye izinto zehydraulic zenziwe ngeRexroth, Kawasaki yaseKorea, i-hydraulic HC yase-Itali, iJiangsu Hengli, iSichuan Changjiang Hydraulic kunye nezinye iibrendi ezaziwayo ekhaya nakwamanye amazwe, ngokusebenza okuphezulu kunye nozinzile.
11. Onke amacandelo abalulekileyo (umboniso kunye nomlawuli) wenkqubo yokulawula umbane ngamacandelo angeniswa kwamanye amazwe kwiimpawu ezidumileyo zamazwe ngamazwe kunye nokupakishwa kwe-original ephezulu; Ibhokisi yokulawula ithatha indawo ethembekileyo yokumisa inqwelomoya kunye neeplagi; Yenza inkqubo yolawulo yombane ekhethekileyo yempompo yasekhaya yokufunxa ireverse circulation rig.
12. I-switchboard ifakwe emva kwezikhululo ezimbini zempompo ze-hydraulic kwaye zigqunywe ngamakhava kunye nezikhululo ezimbini zempompo ze-hydraulic.
13. Njengoko impompo yodaka ibekwe eqongeni, umgama phakathi kwempompo yodaka kunye nomgangatho wamanzi womngxuma wemfumba uyancitshiswa, ukunyuswa kwempompo yodaka kufutshane, kwaye ukusebenza kwempompo yodaka kuphuculwe kakhulu. .
14. Inkcazo yoyilo lombhobho wokubhola:￠325x25x2000 Umbhobho we-drill wamkela uxhulumaniso oludibeneyo, olulungele ukufakela ngokuzenzekelayo kunye nokuqhaqha. Intloko ye-buckle kunye ne-nut kwiziphelo zombini zombhobho we-drill yi-taper ye-rectangular buckle, eyenziwe nge-35CrMo, Icinyiwe kwaye inomsindo, kwaye umbhobho we-drill wenziwa nge-16Mn. Inkqubo ye-welding ithatha ukufudumeza kwangaphambili ngaphambi kwe-welding kunye nokugcinwa kobushushu emva kwe-welding. Umgangatho we-welding ye-drill pipe iqinisekisiwe kwaye ubomi benkonzo buphuculwe.
15. Izixhobo zokugaya: izixhobo zokugaya ezisetyenziswa kwesi sixhobo zixhobo zokugaya ezijikelezayo. Izixhobo ezahlukeneyo zokugaya ziyacetyiswa kubasebenzisi ngokweemeko ezahlukeneyo zejoloji. Ngokwesakhiwo, kukho amaphiko amabini, amaphiko amathathu kunye nezixhobo ezine zokugaya ezijikelezayo; Cylindrical rotary isixhobo sokomba. Ukuhlelwa ngokwamazinyo okubhola: kukho amazinyo okubhola ohlobo lwe-scraper, amazinyo okugaya i-roller kunye namazinyo okugaya i-cutter.
- Iimpawu zokusebenza
1. impompo eludaka eyilwe ziingcali zogcino lwamanzi evela kwiYunivesithi yaseJiangsu yobuchwepheshe yeyona iphambili eTshayina. I-impeller ine-high performance performance, kwaye i-double channel impeller yamkelwa, kunye nefuthe elimangalisayo lokugcina amandla. I-casing yepompo kunye ne-impeller yenziwe ngentsimbi ephezulu ye-chromium kunye nenkqubo yokuphosa utyalo-mali, kunye nokugqitywa kwendawo ephezulu, ukumelana nokunxiba kakuhle kunye nobomi benkonzo ende. I-impeller ithatha uvavanyo oluguquguqukayo lwebhalansi, kunye nebhalansi ephezulu kunye nesantya esikhawulezayo. Logama nje imali ye-impeller ngamasuntswana aqinileyo amancinci kunobubanzi bangaphakathi bombhobho wokubhola, kubandakanya iibhloko zamatye kunye neengqalutye, zinokukhutshwa, ezinqanda ukutyunyuzwa okuphindaphindiweyo kwamasuntswana aqinileyo kunye neengqalutye. Ukusebenza okuphezulu kokususwa kwe-slag.
2. Itorque enkulu kunye namandla okuphakamisa, ngakumbi afanelekele ijoloji entsonkothileyo efana negrabile, ingqalutye kunye namatye;
3. i-manipulator kunye ne-winch yokuncedisa ihlelwe kwifreyimu ye-gantry, efanelekileyo, enokwethenjelwa kunye nokugcinwa kwabasebenzi ekususeni nasekufakeni imibhobho ye-drill;
4. Intloko ejikelezayo: ukuphuma kwamandla rhoqo, ukuhanjiswa ngokuzenzekelayo. Ngaphantsi kweemeko ezahlukeneyo zejoloji, i-motor eguquguqukayo yentloko ejikelezayo ihlengahlengisa ngokuzenzekelayo i-torque yokuphuma kunye nesantya sokuphuma, kunye neqondo eliphezulu lokuzisebenzela, isantya esikhawulezayo se-footage kunye nempumelelo ephezulu yokwakha.
5. Isixhobo kunye nokubonisa isikrini kwi-cab kubonisa idatha yokusebenza kwenkqubo nganye ngexesha langempela, ukwenzela ukuba umqhubi angakwazi ukulawula isimo sokusebenza nangaliphi na ixesha.

- Inkqubo yeprojekthi
Impompo suction reverse circulation sokomba rig. Ngokujikeleziswa kwamanzi, izinto zokusika kwimfumba (iqula) zihanjiswa ngokuqhubekayo ukuya kumngxuma wodaka ecaleni komngxuma (umthombo) kunye nodaka. Emhadini wodaka, isanti, ilitye kunye nezinye izinto zegranular zihlala phantsi kwetanki, kwaye udaka lugeleza kwimfumba (iqula) ngokuqhubekayo. Yongeza inqanaba lamanzi lengqumba. Inkqubo ethile iskim ngolu hlobo lulandelayo:
3.1. Isingxobo semfumba siya kuzinziswa kumngxuma wengqumba. I-pile casing yenziwe ngentsimbi yentsimbi enkulu kune-5mm, kwaye ububanzi bayo buya kuba yi-100mm enkulu kune-design ye-design (well) ububanzi bomngxuma. Ubude be-pile casing buxhomekeke kwiimeko ze-geological. Umda ongezantsi we-pile casing kufuneka ungcwatywe kumhlaba osisigxina kwaye udlule umaleko wokuzalisa umva.
3.2. Ukuba i-backfill inzulu kakhulu kwaye i-excavator okanye umsebenzi wezandla awukwazi ukusebenza, umsebenzisi unokwenza ngokukodwa i-barrel drill bit kwaye ayilungise kwi-drill ukumba imingxuma. Ubunzulu ngokuqhelekileyo abukho ngaphezu kwe-10m. Njengoko imeko inokuba njalo. Musa ukuwa.
3.3. Umthamo wokwembiwa komngxuma wodaka uya kuba mkhulu kunomthamo wengqumba yomngxuma. Kungcono ukusebenzisa i-rectangular shape, enokwandisa ixesha kunye nesantya se-reflux yodaka emngxunyeni wemfumba, kunye nezixhobo zegranular zingahlala phezulu.
