Mtundu Wotsitsa Wotsika
Kapangidwe kakakulu ndi magwiridwe antchito
- Main dongosolo
- Zipangizozi zimatenga crawler chassis, makina a hydraulic opangidwa ndi injini
ndi pampu ya hydraulic yomwe imayikidwa kumbuyo kwa galimotoyo ndikuyendetsa galimoto yochepetsera kuyendetsa galimoto yoyendetsa galimoto, yomwe imazindikira ntchito yodziyendetsa yokha.
2.Majekete anayi a hydraulic amaikidwa kutsogolo ndi kumbuyo kwa njanji. Makina akuluakulu amatha kuthandizidwa ndipo magawo akutsogolo, kumbuyo, kumanzere ndi kumanja amatha kusinthidwa popanda kuwongolera pansi pa malo omanga. Jacks akhoza kutsegulidwa ndi kutsekedwa momasuka pansi pa ulamuliro wosiyana. Pakumanga, ma jacks a hydraulic amawonjezedwa, ndipo m'lifupi mwake fulcrum yakumanzere ndi kumanja imatha kufika 3.8m.
3. Gantry ya pobowola rig imakhazikika kutsogolo kwa nsanja ya chassis ndikuyikidwa molunjika (boma logwira ntchito).
4. Gantry frame ndi chitseko chotsegulira chitseko kumapeto kwa m'munsi ndi dongosolo lophatikizidwa, lomwe limapangitsa kwambiri kukhazikika kwa dongosolo lonse la chimango.
5. Gantry subframe imayikidwa mkati mwa gantry, zomwe sizimangowonjezera machitidwe otsogolera, komanso zimapangitsa kuti zomangamanga zikhale zolimba, komanso zimatalikitsa moyo wautumiki wa chitoliro chobowola. Mutu wamagetsi umayikidwa mkati mwa kumapeto kwa gantry subframe. Silinda ya hydraulic yomwe imagwiritsidwa ntchito kukweza mutu wamagetsi (kuphatikiza subframe) imayikidwa mu chubu lalikulu la mullion wa subframe.
6. mutu wozungulira umagwiritsa ntchito mutu wozungulira wa makina obowola, omwe amawonjezera torque.
yoyendetsedwa ndi ma motors atatu 107 osinthika
7. Miliyoni yoyenera ya gantry imakhala ndi makina oyendetsa galimoto ndi crane ya cantilever (yopangidwa ndi hydraulic winch, cantilever, pulley, etc.). Ntchito disassembling ndi kusonkhanitsa mapaipi kubowola.
8. Pafupi ndi kumbuyo kwa gantry, gawo lapakati ndi lakutsogolo la nsanja lili ndi kabati, yomwe ili ndi opareshoni, chophimba chowonetsera, chowongolera mpweya, ndi zina zotero.
9. Kumbuyo kwa kabati ndi pakati pa nsanja, pampu ya slurry imayikidwa. Pampu ya slurry imayendetsedwa mwachindunji ndi injini ya 90kw. Kutaya mphamvu kwa kutembenuka kwa magetsi ndi ma hydraulic kumapewa. Panthawi imodzimodziyo, ndalama zomanga zimachepetsedwa.
10. Pamalo opopera ma hydraulic kumbuyo kwa nsanja, makina awiri odziyimira pawokha amayikidwa:
10.1 The kuyenda hayidiroliki dongosolo wapangidwa ndi Cummins 197kw injini dizilo ndi zoipa otaya mosalekeza mphamvu variable mpope, amene ntchito galimoto kuyenda, main injini outrigger yamphamvu, khomo kutsegula chimango outrigger yamphamvu, kukweza yamphamvu ndi zina actuating zinthu. Ndikoyenera kuyenda pamalo omanga ndikugwirizanitsa mabowo a mulu wa pobowola.
10.2 The rotary head hydraulic system imapangidwa ndi 132kw atatu-phase asynchronous motor and negative flow variable mphamvu pampu, yomwe imagwiritsidwa ntchito pamutu wozungulira, kukweza silinda yamafuta, silinda yamafuta oyendetsa, ma hydraulic winch ndi zinthu zina zoyambitsa.
Advanced hydraulic system idapangidwa mwapadera kuti pampu suction reverse circulation. Pampu yayikulu, mota yozungulira mutu, valavu yayikulu, valavu yothandizira yonyamula katundu ndi zida zina zama hydraulic zimapangidwa ndi Rexroth, Kawasaki waku Korea, hydraulic HC waku Italy, Jiangsu Hengli, Sichuan Changjiang Hydraulic ndi zinthu zina zodziwika bwino kunyumba ndi kunja, ndi magwiridwe antchito apamwamba komanso okhazikika.
11. Zigawo zonse zazikulu (zowonetsera ndi zowongolera) za kayendedwe ka magetsi ndizochokera kunja kwa mitundu yotchuka yapadziko lonse ndi mapepala apamwamba apamwamba; Bokosi lowongolera limatenga malo odalirika oyendetsa ndege ndi mapulagi; Pangani dongosolo lapadera lamagetsi lapampu yapanyumba yoyamwa reverse circulation pobowola.
12. Chophimbacho chimayikidwa kumbuyo kwa mapampu awiri a hydraulic pump ndipo amaphimbidwa ndi zophimba pamodzi ndi mapampu awiri a hydraulic pump.
13. Pamene mpope wamatope umayikidwa pa nsanja, mtunda wa pakati pa mpope wamatope ndi madzi pamwamba pa dzenje la mulu umachepetsedwa, kukweza kwapope yamatope kumafupikitsidwa, ndipo ntchito yogwira ntchito ya pampu yamatope imakhala bwino kwambiri. .
14. Kapangidwe ka chitoliro chobowola:￠325x25x2000 chitoliro kubowola utenga ulusi kugwirizana, amene ndi yabwino unsembe basi ndi disassembly. Mutu wa buckle ndi mtedza kumapeto kwa chitoliro chobowola ndi chomangira chozungulira, chopangidwa ndi 35CrMo, Chozimitsidwa ndi kupsya mtima, ndipo chitoliro chobowola chimapangidwa ndi 16Mn. Kuwotcherera kumatenga kutentha kusanayambe kuwotcherera ndi kuteteza kutentha pambuyo kuwotcherera. Kuwotcherera kwa chitoliro cha kubowola kumatsimikiziridwa ndipo moyo wautumiki umakhala wabwino.
15. Zopangira pobowola: zida zobowola zomwe zimagwiritsidwa ntchito pazida izi ndi zida zoboola mozungulira. Zopangira zobowola zosiyanasiyana zimalimbikitsidwa kwa ogwiritsa ntchito molingana ndi mikhalidwe yosiyanasiyana ya geological. Malinga ndi kapangidwe kake, pali zida ziwiri zoboola mapiko, mapiko atatu ndi mapiko anayi; Chida chobowola mozungulira cylindrical. Gulu pobowola mano: pali mano obowola amtundu wa scraper, mano obowola ndi odula.
- Makhalidwe amachitidwe
1. mpope wa slurry wopangidwa ndi akatswiri osunga madzi kuchokera ku yunivesite ya Jiangsu yaukadaulo ndiyotsogola kwambiri ku China. Impeller imakhala yogwira ntchito kwambiri, ndipo chowongolera chapawiri chimatengedwa, chokhala ndi mphamvu zopulumutsa mphamvu. Choyikapo pampu ndi chopondera amapangidwa ndi chitsulo cha chromium chapamwamba komanso njira yopangira ndalama, yokhala ndi kutha kwapamwamba, kukana kuvala bwino komanso moyo wautali wautumiki. Impeller imatenga mayeso osinthika, okhala ndi liwiro lalikulu komanso kuthamanga. Malingana ngati ndalama za chipolopolo ndi tinthu tating'onoting'ono tating'onoting'ono tating'onoting'ono tabowo, kuphatikizapo miyala yamtengo wapatali ndi timiyala, titha kumasulidwa, zomwe zimapewa kuphwanya mobwerezabwereza tinthu tating'onoting'ono ndi timiyala. High slag kuchotsa bwino.
2. Torque yayikulu ndi mphamvu yonyamulira, makamaka yoyenera pazachilengedwe zovuta monga miyala, miyala ndi miyala;
3. manipulator ndi winch wothandizira amakonzedwa pa chimango cha gantry, chomwe chiri chosavuta, chodalirika komanso chopulumutsa ntchito pochotsa ndi kukhazikitsa mapaipi obowola;
4. Mutu wozungulira: kutulutsa mphamvu kosalekeza, kutumiza kwadzidzidzi. Pansi pamikhalidwe yosiyanasiyana ya geological, mota yosinthika ya mutu wozungulira imangosintha ma torque ndi liwiro lotulutsa, ndi makina apamwamba kwambiri, kuthamanga kwazithunzi komanso magwiridwe antchito apamwamba.
5. Chida ndi chophimba chowonetsera mu kabati chimasonyeza deta ya ntchito ya dongosolo lililonse mu nthawi yeniyeni, kotero kuti woyendetsa akhoza kudziwa momwe ntchitoyo ikuyendera nthawi iliyonse.

- Ndondomeko ya polojekiti
Pump suction reverse circulation pobowola cholumikizira. Pogwiritsa ntchito kayendedwe ka madzi, zida zodulira mu mulu (chitsime) zimasamutsidwa mosalekeza kupita ku dzenje lamatope pafupi ndi dzenje la mulu (chitsime) pamodzi ndi matope. M'dzenje lamatope, mchenga, miyala ndi zinthu zina zazing'ono zimakhazikika pansi pa thanki, ndipo matope amayenda mu dzenje (chitsime) mosalekeza. Wonjezerani mulingo wamadzi wa dzenje la mulu. Ndondomeko ya ndondomekoyi ili motere:
3.1. Chophimbacho chiyenera kuyikidwa pamwamba pa khungu. Chophimbacho chimapangidwa ndi mbale yachitsulo yokulirapo kuposa 5mm, ndipo m'mimba mwake iyenera kukhala 100mm yokulirapo kuposa mulu wopangira (chitsime) m'mimba mwake. Kutalika kwa mulu casing kumadalira pa geological zinthu. M'mphepete m'munsi mwa mulu casing ayenera kukwiriridwa mu okhazikika nthaka wosanjikiza ndi kupitirira backfill wosanjikiza.
3.2. Ngati kubweza kumbuyo kuli kozama kwambiri ndipo chofufutira kapena ntchito yamanja sichingagwire ntchito, wogwiritsa ntchito amatha kupanga pobowola mbiya ndikuyikonza pobowola kuti akumbire mabowo. Kuzama sikuposa 10m. Monga momwe zingakhalire. Osagwa.
3.3. Kuchuluka kwa dzenje lamatope kumakhala kwakukulu kuposa kuchuluka kwa dzenje la mulu. Ndi bwino kugwiritsa ntchito mawonekedwe amakona anayi, omwe amatha kutalikitsa nthawi ndi liwiro la matope reflux mu dzenje la mulu, ndipo zinthu za granular zimatha kukhazikika mpaka pazipita.
