Ucingo:
I-imeyili:
Nakuba ogandaganda kanye nogandaganda bokumba kuyimishini yokwakha evamile futhi kokubili kuyasetshenziswainqola engaphansi kwenqola yokukhasa, indawo yokusebenza kwazo ihluke ngokuphelele, okuholela ngqo ekwehlukeni okukhulu ekwakhiweni kwezihlalo zazo zangaphansi kwenqola.
Ake senze ukuqhathanisa okuningiliziwe kusuka ezicini eziningana ezibalulekile:
1. Umehluko Emisebenzini Eyinhloko kanye Nemibono Yokuklama
Imisebenzi Eyinhloko:
Inqola engaphansi kwe-bulldozer: Ihlinzeka ngokunamathela okukhulu komhlabathi kanye nepulatifomu yokusekela eqinile yokusebenza kokugumbuqela.
Inqola engaphansi kwenqola evamile yokwemba: Ihlinzeka ngesisekelo esizinzile nesiguquguqukayo sedivayisi engenhla ukuze yenze imisebenzi yokumba ejikelezayo engu-360°.
Umqondo Wokuklama:
Inqola engaphansi kwe-bulldozer: Ukusebenza okuhlanganisiwe: Umzimba wemoto uxhunywe ngokuqinile nedivayisi esebenzayo (i-scythe). I-chassis idinga ukuthwala amandla amakhulu okusabela okuwa.
Isithuthi sangaphansi kwemoto yomvubukuli ojwayelekile: Ukusebenza okuhlukanisiwe: Inqola engaphansi kwemoto engezansi iyisithwali esiphathwayo, kanti idivayisi engenhla iyisitho esisebenzayo. Zixhunywe ngokusekelwa okujikelezayo.
Ubudlelwano Nedivayisi Esebenzayo:
Inqola engaphansi kwe-bulldozer: Idivayisi esebenzayo (i-scythe) iboshwe ngokuqinile ohlakeni lwenqola engaphansi kwe-bulldozer. Amandla okusunduza athwalwa ngokuphelele futhi adluliselwe yinqola engaphansi kwe-bulldozer.
Inqola engaphansi kwenqola evamile yokumba: Idivayisi esebenzayo (ingalo, ibhakede, ibhakede) ifakiwe epulatifomu yemoto engaphezulu. Amandla okumba athwalwa kakhulu yisakhiwo semoto engenhla, kanti inqola engaphansi kwenqola ithwala kakhulu isikhathi sokugumbuqela kanye nesisindo.
2. Izakhiwo Ezithile Nomehluko Wobuchwepheshe
Uhlaka Lokuhamba kanye Nesakhiwo Se-Chassis
I-Bulldozer:
• Isebenzisa i-subcarriage eqinile ehlanganisiwe: Uhlelo lwe-subcarriage ngokuvamile luyisakhiwo esiqinile esixhunywe ngokuqinile ne-subcarriage eyinhloko.
• Inhloso: Ukuqinisekisa ukuthi amandla amakhulu okusabela ngesikhathi sokudilizwa angadluliselwa ngqo futhi ngaphandle kokulahlekelwa kuyo yonke indawo engaphansi kwenqola, okuqinisekisa ukuzinza kanye nekhono lokusebenza elinamandla lomshini.
Umvubukuli:
• Isebenzisa uhlaka lwemoto oluphansi olunesimo se-X noma se-H, oluxhunywe kudivayisi engenhla ngezisekelo ezijikelezayo.
• Inhloso: Uhlelo lwesitimela esingaphansi kwemoto lusebenza kakhulu emisebenzini yokusekela nokunyakaza. Umklamo walo kufanele uqinisekise ukuthi isisindo sepulatifomu yemoto engenhla kanye namandla okusabela okumba kungasatshalaliswa ngokulinganayo ngesikhathi sokujikeleza okungu-360°. Isakhiwo se-X/H singasabalalisa ngempumelelo ukucindezeleka futhi sinikeze isikhala sokufaka idivayisi ejikelezayo.
Ukuhlelwa Kwesondo Elithwala Ithrekhi Nemithwalo
I-Bulldozer:
• Igeyiji yethrekhi ibanzi, i-undercarriage iphansi, kanti isikhungo samandla adonsela phansi siphansi.
• Inani lama-track rollers likhulu, usayizi mncane kakhulu, futhi ahlelwe eduze, cishe amboze ubude bomhlaba wonke we-track.
• Inhloso: Ukwandisa indawo yokuxhumana komhlabathi, ukunciphisa ingcindezi yomhlabathi, ukunikeza ukuzinza okuhle kakhulu, nokuvimbela ukugoba noma ukugumbuqela ngesikhathi sokuwa. Amasondo athwele umthwalo aseduze angadlulisela isisindo kangcono epuletini lomzila futhi azivumelanise nomhlabathi ongalingani.
Umvubukuli:
• Igeyiji yethrekhi incane kakhulu, i-undercarriage iphakeme, okwenza kube lula ukuqondisa nokuwela izithiyo.
• Inani lama-track rollers lincane, usayizi mkhulu, futhi isikhala sibanzi.
• Inhloso: Ukuthuthukisa ukukwazi ukudlula kanye nokuguquguquka ngenkathi kuqinisekiswa ukuzinza okwanele. Amasondo amakhulu athwala imithwalo kanye nesikhala esibanzi kusiza ekusakazeni imithwalo yomthelela ekhiqizwa ngesikhathi sokumba okunamandla.
Indlela Yokushayela Nokudlulisa
I-Bulldozer:
• Ngokwesiko, isebenzisa kakhulu i-hydraulic mechanical transmission. Amandla enjini adlula ku-torque converter, i-gearbox, i-central transmission, i-steering clutch, kanye ne-final drive, ekugcineni ifinyelela kuthrekhi kanye ne-sprocket.
• Izici: Ukusebenza kahle kokudlulisa okuphezulu, kunganikeza ukubamba okuqhubekayo nokunamandla, okulungele ukukhishwa kwamandla okuqhubekayo okudingekayo ekusebenzeni kokugumbuqela.
Umvubukuli:
• Abavubukuli besimanje ngokuvamile basebenzisa ukudluliselwa kwe-hydraulic. Ithrekhi ngayinye iqhutshwa yinjini ye-hydraulic ezimele.
• Izici: Ingafinyelela ukuqondisa endaweni, ukushelela okuhle kakhulu. Ukulawula okunembile, kulula ukulungisa indawo ezindaweni ezincane.
Uhlelo Lokucindezela Nokumisa
I-Bulldozer:
• Ngokuvamile kusetshenziswa ukumiswa okuqinile noma ukumiswa okuqinile kancane. Akukho noma kukhona ukuhamba okuncane kwe-buffer phakathi kwamasondo athwala umthwalo kanye ne-chassis.
• Inhloso: Emisebenzini ephansi, ukumiswa okuqinile kunganikeza ukwesekwa okuzinzile kakhulu, okuqinisekisa ikhwalithi yokusebenza ephansi.
Umvubukuli:
• Ngokuvamile isebenzisa idivayisi yokucindezela igesi kawoyela enomshini womoya. Amasondo athwala umthwalo axhunywe ku-chassis ngokusebenzisa uwoyela we-hydraulic kanye negesi ye-nitrogen buffering.
• Inhloso: Ukumunca ngempumelelo umthelela kanye nokudlidliza ngesikhathi sokumba, ukuhamba, nokuhamba, ukuvikela isakhiwo semoto esinembile kanye nohlelo lwe-hydraulic, kanye nokuthuthukisa induduzo yokusebenza kanye nesikhathi sokuphila komshini.
Izici zokugqoka ze-"four rollers and one track"
Itrektara:
• Ngenxa yokusebenza njalo kokuqondisa kanye nokunyakaza okuqondile, izinhlangothi ze-idler yangaphambili kanye ne-chain tracks ye-track zigugile kakhulu.
Umvubukuli:
• Ngenxa yokusebenza njalo kokujikeleza endaweni, ukuguguleka kwama-track rollers nama-top rollers kugqame kakhulu, ikakhulukazi ingxenye yomphetho.
3. Isifinyezo:
• Inqola engaphansi kwetrektara ifana nomzimba ongezansi womdlali we-sumo osindayo, oqinile futhi ozinzile, ogxile ngokuqinile emhlabathini, ngenhloso yokusunduza umphikisi phambili.
• Inqola engaphansi kwe-excavator ifana nesisekelo se-crane esiguquguqukayo, esinikeza isisekelo esizinzile se-boom ephezulu futhi ikwazi ukulungisa isiqondiso nendawo njengoba kudingeka.
