Lub tshuab crawler hydraulic excavator yog lub tshuab txav hauv ntiaj teb uas siv lub thoob los khawb cov ntaub ntawv saum toj lossis hauv qab ntawm cov kabmob thiab thauj mus rau hauv lub tsheb thauj mus los lossis thauj mus rau qhov chaw khaws khoom.Cov ntaub ntawv excavated feem ntau yog av, thee, silt, av thiab pob zeb tom qab pr-loosing.
Judging los ntawm txoj kev loj hlob ntawm kev tsim kho machinery nyob rau hauv xyoo tas los no, txoj kev loj hlob ntawm excavators yog ceev heev.Raws li ib qho ntawm cov qauv siv tshuab tseem ceeb tshaj plaws hauv kev tsim kho engineering, kev xaiv raug ntawm excavators tseem ceeb dua.Cov tshuab tshwj xeeb thiab cov cuab yeej siv dav siv hauv kev tsuas thiab kev tsim kho hauv nroog thiab nyob deb nroog nrog kev ua tau zoo thiab cov cuab yeej tshwj xeeb.
Suav lub npe: Crawler hydraulic excavator
Lub npe txawv teb chaws: excavating machinery
Siv: mining thiab kev tsim kho hauv nroog thiab nyob deb nroog
Taw qhia: khawb thiab sau cov khoom nrog lub thoob
Nws tau ntau dua 130 xyoo txij li thawj phau ntawv excavator tuaj tawm.Nyob rau lub sijhawm no, nws tau dhau los ua qhov kev loj hlob zuj zus los ntawm cov tshuab hluav taws xob uas tau tsav los ntawm lub thoob teb excavators mus rau hluav taws xob-tsav thiab sab hauv-combustion-engine-driven rotary excavators, thiab tag nrho tsis siv neeg hydraulic excavators siv electroencephalographic.integration technology.txheej txheem.
Vim yog kev siv tshuab hydraulic, muaj ib lub tshuab mounted excavator nruab nrog hydraulic backhoe ntawm lub tsheb laij teb hauv xyoo 1940.Thaum ntxov thiab nruab nrab-1950s, azimuth hydraulic excavator thiab crawler tag nrho hydraulic excavator tau ua tiav..
Thawj qhov kev sim ua hydraulic excavator txais kev siv tshuab hydraulic ntawm lub dav hlau thiab cov cuab yeej siv tshuab, tsis muaj cov khoom siv hydraulic haum rau ntau yam kev ua haujlwm ntawm lub excavator, kev tsim khoom tsis ruaj khov txaus, thiab cov khoom txhawb nqa tsis tiav.
Txij li thaum xyoo 1960, hydraulic excavators tau nkag mus rau theem ntawm kev txhawb nqa thiab kev loj hlob zoo.Tus naj npawb ntawm excavator manufacturers thiab ntau yam nyob rau hauv ntau lub teb chaws tau nce sai heev, thiab cov zis tau soared.
Los ntawm 1968 mus rau 1970, cov zis ntawm hydraulic excavators account rau 83% ntawm tag nrho cov zis ntawm excavators, thiab tam sim no nws yog ze rau 100%.
Lub excavator yog Ameslikas phau ntawv, thiab nws tau ntau tshaj 130 xyoo txij li thaum nws invention, thiab nws tau ntsib ntau yam kev tsav tsheb xws li chav tsav, hluav taws xob tsav, thiab sab hauv combustion engine tsav.
Tom qab xyoo 1940, cov tshuab hydraulic tau siv rau cov tshuab excavators, thiab nyob rau xyoo 1950, cov crawler-type full-hydraulic excavators uas niaj hnub no tau tsim.
Peb qhov tseem ceeb tshaj plaws ntawm excavators: lub tsheb hnyav (ntau), lub zog ntawm lub cav thiab lub peev xwm thoob.
Nyob rau hauv 1951, thawj tag nrho hydraulic backhoe tau pib ntawm McClainHoobkas nyob rau hauv Fabkis, yog li tsim ib tug tshiab qhov chaw nyob rau hauv lub tshav pob ntawm kev loj hlob ntawm excavators.
ua
Cov txheej txheem excavator feem ntau suav nrog cov khoom siv hluav taws xob, cov khoom siv ua haujlwm, slewing mechanisms, kev siv tshuab, kev sib kis, kev taug kev mechanisms thiab cov chaw pabcuam.
Los ntawm cov tsos, lub excavator yog tsim los ntawm peb qhov chaw: lub tshuab ua hauj lwm, lub sab sauv turntable thiab mus ncig teb chaws mechanism.
Kev faib tawm
Cov hauv qab no yog ib qho kev faib ua feem ntawm cov excavators:
Qeb 1: Feem ntau excavators muab faib ua ob hom: sab hauv combustion engine-driven excavators thiab hluav taws xob-driven excavators.Ntawm lawv, hluav taws xob excavators tsuas yog siv nyob rau hauv toj siab hypoxia, underground mines thiab lwm qhov chaw flammable thiab tawg.
Kev faib tawm 2: Raws li txoj kev taug kev sib txawv, excavators tuaj yeem muab faib ua crawler excavators thiab wheeled excavators.
Kev faib tawm 3: Raws li kev sib kis sib txawv, excavators tuaj yeem muab faib ua hydraulic excavators thiab mechanical excavators.Cov tshuab excavators feem ntau yog siv hauv qee qhov mines loj.
Classification 4: Raws li kev siv, excavators tuaj yeem muab faib ua dav dav excavators, mining excavators, marine excavators, tshwj xeeb excavators thiab lwm yam sib txawv pawg.
Feem ntau ntawm cov niaj hnub excavators yog tag nrho hydraulic azimuth excavators.Kab ntsig 385B Excavator
Hydraulic excavators yog tsim los ntawm lub cav, hydraulic system, ua hauj lwm ntaus ntawv, mus txawv tebchaws ntaus ntawv thiab hluav taws xob tswj.Lub tshuab hydraulic muaj cov twj tso kua mis hydraulic, tswj valve, hydraulic lub tog raj kheej, hydraulic lub cev muaj zog, cov kav dej, roj tank, thiab lwm yam. Lub tshuab hluav taws xob muaj xws li kev tswj xyuas vaj huam sib luag, lub cav tswj qhov system, twj tso kua mis tswj system, ntau yam sensors, solenoid li qub, thiab lwm yam.
Raws li nws cov qauv thiab kev siv, nws tuaj yeem muab faib ua:
Crawler hom, hom log tsheb, hom taug kev, tag nrho hydraulic, semi-hydraulic, azimuth, non-azimuth, general, tshwj xeeb, articulated, telescopic boom thiab lwm yam.
Cov cuab yeej ua haujlwm yog cov cuab yeej uas ncaj qha ua tiav cov haujlwm excavation.Nws yog hinged los ntawm peb qhov chaw: boom, stick thiab thoob.Boom nqa, stick extension thiab thoob rotation yog tswj los ntawm reciprocating ob-acting hydraulic thooj voos kheej kheej.
Txhawm rau ua kom tau raws li qhov xav tau ntawm ntau yam kev tsim kho, hydraulic excavators tuaj yeem nruab nrog ntau yam khoom siv ua haujlwm, xws li khawb, nqa, thauj khoom, theem, clamps, bulldozing, cuam tshuam rauj thiab lwm yam cuab yeej ua haujlwm.
Lub slewing thiab mus ncig ua si yog lub cev ntawm hydraulic excavator, thiab sab sauv ntawm lub turntable yog muab nrog ib lub hwj chim ntaus ntawv thiab ib tug kis tau tus mob system.Lub cav yog lub zog ntawm hydraulic excavator, feem ntau siv cov roj diesel nyob rau hauv qhov chaw yooj yim, thiab tseem tuaj yeem siv lub tshuab hluav taws xob hloov.
Lub hydraulic kis tau tus mob kis tau lub zog ntawm lub cav mus rau lub hydraulic lub cev muaj zog, hydraulic lub tog raj kheej thiab lwm yam actuators los ntawm lub hydraulic twj tso kua mis, thiab thawb lub twj tso kua mis ua hauj lwm, yog li ua tiav ntau yam kev khiav hauj lwm.
