Kulankhula za Gulu ndi kapangidwe ka ntchito ka ma bulldozer okwera

Classification njira yoyenda
Mabulldozer amatha kugawidwa m'mitundu iwiri: mtundu wa crawler ndi mtundu wa matayala.Bulldozer ya crawler imakhala ndi zomatira zazikulu komanso zokokera, kupanikizika kwakung'ono komwe kumayambira (0.04-0.13MPa), kutha kukwera mwamphamvu, koma liwiro lotsika.Bulldozer yamtundu wa matayala imakhala ndi liwiro lalikulu, kusinthasintha kosinthika, nthawi yayitali yozungulira, mayendedwe osavuta komanso kusamutsa, koma mphamvu yaying'ono yoyenda, yomwe ili yoyenera momwe malo omanga ndi ntchito zakumunda ziyenera kusinthidwa pafupipafupi.

Pogwiritsa ntchito
Ikhoza kugawidwa mumtundu wamba ndi mtundu wapadera.Mtundu wa zolinga zonse ndi chitsanzo chomwe chimapangidwa molingana ndi muyezo, ndipo chimagwiritsidwa ntchito kwambiri mu engineering ya Earthwork.Mtundu wapaderawu umagwiritsidwa ntchito m'malo ogwirira ntchito, kuphatikiza ma bulldozer a madambo ndi ma bulldozer a madambo, ma amphibious bulldozers, ma bulldozers apansi pamadzi, ma bulldozer a kanyumba, ma bulldozer opanda anthu, mapiri ndi ma Bulldozer apamwamba omwe amagwira ntchito m'madzi, ndi zina zambiri.

Mawu Oyamba
Makamaka ndi ma bulldozer acholinga chambiri, ma bulldozer amtundu wa madambo ndi ma bulldozer omwe amasinthidwa ndi chitukuko chakumadzulo kwa mtundu wa mapiri.Pambuyo pa zaka zoposa 20 zachitukuko chokhazikika, makampani a bulldozer a dziko langa apangidwa kuchokera ku 59kW (80 horsepower, Shantui SD08 bulldozer, mu chivomezi cha 5.12 Wenchuan, Russian Mi-26 helikopita idakwezedwa kumalo omanga) mpaka 309kW (420 ndiyamphamvu, Bulldozer ya SD42 yopangidwira Shantui imatumizidwa ku Russia.

Kuphatikiza apo, palinso mitundu yosiyanasiyana yazogulitsa zokhala ndi ma module osinthika mosiyanasiyana malinga ndi zosowa zamitundu yosiyanasiyana yogwirira ntchito, zomwe zimakwaniritsa zofunikira za uinjiniya wapakhomo pazogulitsa bulldozer.Kuphatikiza apo, makina osiyanasiyana a Shantui, makamaka ma bulldozers, amatumizidwanso mosalekeza kumayiko akunja.Idatumizidwa kumayiko ndi zigawo 103, ndikutsegula msika wapadziko lonse lapansi.

kapangidwe ndi ntchito
Mabulldozer ndi mtundu waukulu wa makina osuntha nthaka.Amagawidwa m'mitundu iwiri: mtundu wa crawler ndi mtundu wa matayala.Chifukwa pali ma bulldozer amtundu wa matayala ochepa.Nkhaniyi ikufotokoza za kamangidwe ndi mfundo zogwirira ntchito za bulldoza yokwawa.Ntchito zofukula bulldoza ndi izi: A. Fosholo B. Kusuntha nthaka C. Kutsitsa.
Ambiri mwa ma bulldozers omwe ali ndi mphamvu yoposa 120KW amagwiritsa ntchito ma hydraulic-mechanical transmission.Bulldozer yamtunduwu imachokera ku mitundu itatu yayikulu yaukadaulo wopanga ma bulldozer, D155, D85 ndi D65 yoyambitsidwa ndi Komatsu, Japan.Pambuyo pakukhazikika, imamalizidwa ngati TY320, TY220 ndi TY160 ma bulldozer oyambira.

Pofuna kukwaniritsa zosowa za ogwiritsa ntchito m'malo osiyanasiyana ogwira ntchito, opanga ma buldoza m'dziko langa awonjezera mitundu yawo yazinthu ndikupanga ma bulldozer atatu pamaziko a ma buldoza atatu omwe ali pamwambapa.TY220 bulldozer mndandanda mankhwala monga TSY220 madambo bulldozer, TMY220 chipululu bulldozer, TYG220 plateau bulldozer, TY220F nkhalango kudula bulldozer, TSY220H ukhondo bulldozer ndi DG45 pipelayer, etc. The TY360 zotsatizana ndi zoonjezera zotsatizana.Mu mndandanda wa TY160, pali TSY160L ma bulldozer owonjezera kwambiri komanso okankhira a TBY160.

Kukula ndi kukula kwa mitundu ya bulldozers kuyenera osati kukumana ndi kusinthika kwa ntchito zamitundu yosiyanasiyana yogwirira ntchito, komanso kukhalabe ndi kusinthasintha kwakukulu (kapena kusinthasintha) kwa magawo ndi zigawo ndi mtundu woyambira, womwe umabweretsa phindu lalikulu pakugwiritsa ntchito ndi kukonza ambiri ogwiritsa ntchito.Zabwino kwambiri.Pofuna kuthandizira ogwiritsa ntchito kugula zowonjezera, opanga adasunga ziwerengero za Komatsu Corporation ya Japan, ndipo magawo okhawo omwe adapangidwa okha pakusinthidwa amatchulidwa ndi nambala ya opanga awo.

Crawler bulldozer imapangidwa makamaka ndi injini, makina opatsirana, chipangizo chogwirira ntchito, gawo lamagetsi, kabati ndi hood.Zina mwa izo, makina ndi ma hydraulic transmission system amaphatikizanso chosinthira ma hydraulic torque, msonkhano wolumikizira, kufalitsa mphamvu zapadziko lapansi, kufalikira kwapakati, chiwongolero chowongolera ndi mabuleki owongolera, kuyendetsa komaliza ndi kayendedwe kaulendo.

Njira yochotsera mphamvu imayendetsa pampu yogwirira ntchito mu hydraulic system ya chipangizo chogwirira ntchito, pampu yosinthira liwiro la ma torque variable variable hydraulic system, ndi mpope wowongolera wa brake hydraulic system pogwiritsa ntchito zida zotumizira ndi kulumikizana kwa spline;sprocket imayimira njira yomaliza yoyendetsa magalimoto achiwiri a spur gear (kuphatikiza kumanzere ndi kumanja komaliza koyendetsa);Nsapato za crawler zimaphatikizapo kusonkhana kwa crawler, chimango cha trolley ndi msonkhano woyimitsidwa kuphatikizapo kayendedwe ka kuyenda.
