Excavator Classification

Muaj ob txoj kev tsav tsheb rau excavators: sab hauv combustion cav tsav excavators thiab hluav taws xob excavators. Hluav taws xob excavators yog siv nyob rau hauv high-altitude hypoxia, underground mines, thiab lwm yam flammable thiab tawg qhov chaw.
Raws li qhov ntau thiab tsawg, excavators yuav muab faib ua loj excavators, nruab nrab excavators, thiab me excavators.
Raws li kev taug kev sib txawv, excavators tuaj yeem muab faib ua kev taug qab excavators thiab log excavators.
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.
Raws li lawv siv, excavators tuaj yeem muab faib ua ntau pawg xws li cov hom phiaj dav dav excavators, mining excavators, marine excavators, thiab tshwj xeeb excavators.
Raws li cov thoob, excavators tuaj yeem muab faib ua rau pem hauv ntej shovel excavators, backhoe excavators, rub duav excavators, thiab rub duav excavators. Cov khauj khaum excavators feem ntau yog siv los khawb cov ntaub ntawv saum npoo av, thaum backhoe excavators feem ntau yog siv los khawb cov ntaub ntawv hauv qab no.
1. Backhoe excavator
Hom backhoe yog qhov ntau tshaj plaws uas peb tau pom, uas yog rov qab thiab nqes, nrog rau kev quab yuam cov av. Nws tuaj yeem siv rau kev khawb hauv qab qhov chaw ua haujlwm kaw, thiab cov txheej txheem ua haujlwm yooj yim suav nrog: trench kawg excavation, trench side excavation, ncaj excavation, nkhaus excavation, excavation ntawm ib lub kaum ntse ntse, ultra tob trench excavation, thiab trench nqes hav excavation.
2. Pem hauv ntej duav excavator
Kev ua haujlwm ntawm shovel daim ntawv ntawm lub hauv ntej duav excavator. Nws tus yam ntxwv yog txav mus rau pem hauv ntej thiab yuam cov av txiav. Lub shovel pem hauv ntej muaj ib tug loj excavation quab yuam thiab yuav excavate av saum lub tshuab nres nto. Nws yog tsim rau excavating qhuav foundation pits nrog qhov siab tshaj 2 meters, tab sis nce toj thiab downhill ramps yuav tsum tau teem. Lub thoob excavator ntawm lub duav pem hauv ntej yog loj dua li ntawm lub thoob excavator ntawm tib qhov sib npaug backhoe. Nws tuaj yeem khawb hauv Chav Kawm I mus rau III av nrog cov dej noo tsis tshaj 27%, thiab koom tes nrog cov tsheb thauj khoom kom tiav tag nrho kev khawb thiab kev thauj mus los. Nws tseem tuaj yeem khawb qhov loj qhuav hauv paus pits thiab av mounds. Txoj kev excavation ntawm lub hauv ntej duav excavator nws txawv nyob ntawm seb tus txheeb ze ntawm txoj kev excavation thiab tsheb thauj mus los. Muaj ob txoj hauv kev los khawb thiab tshem tawm cov av: pem hauv ntej excavation thiab lateral unloading; Forward excavation thiab thim rov qab unloading.
3. rub duav excavator
Rub duav excavator, tseem hu ua cable shovel excavator. Nws excavation yam ntxwv yog: "rov qab downward, txiav cov av los ntawm nws tus kheej hnyav." Haum rau excavation ntawm Class I thiab II av hauv qab qhov chaw nres tsheb. Thaum ua hauj lwm, siv inertia quab yuam pov lub thoob tawm, khawb kuj deb, nrog ib tug loj excavation vojvoog thiab qhov tob, tab sis tsis raws li saj zawg zog thiab yog raws li ib tug backhoe. Tshwj xeeb tshaj yog tsim rau excavating loj thiab tob foundation pits los yog underwater excavation.
4. Grab shovel excavator
Grab shovel excavator, tseem hu ua grab thoob excavator. Nws cov yam ntxwv excavation yog: "ncaj nce thiab ncaj nraim, txiav cov av los ntawm nws tus kheej qhov hnyav." Haum rau excavation ntawm Class I thiab II av hauv qab qhov chaw nres tsheb, feem ntau siv nyob rau hauv cov av mos rau excavation ntawm lub hauv paus pits, caissons, thiab lwm yam. Tshwj xeeb tshaj yog tsim rau excavating tob thiab nqaim foundation pits, dredging qub raws, thiab extracting silt los ntawm dej, los yog rau kev thauj khoom xoob xws li pob zeb crushed thiab slag. Muaj ob txoj kev excavation: trench side excavation thiab positioning excavation. Yog tias lub thoob ntim tau ua rau hauv daim phiaj zoo li cov duab, nws tuaj yeem siv los thauj cov ore blocks, ntoo chips, ntoo, thiab lwm yam.
Feem ntau ntawm cov niaj hnub excavators yog tag nrho hydraulic tag nrho rotation excavators. Hydraulic excavators yog tsim los ntawm cov cav, hydraulic systems, ua hauj lwm pab kiag li lawm, taug kev li, thiab hluav taws xob tswj. Lub tshuab hydraulic muaj xws li lub twj tso kua mis hydraulic, tswj valve, hydraulic lub tog raj kheej, hydraulic lub cev muaj zog, 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 lub tshuab, twj tso kua mis tswj tshuab, ntau yam sensors, solenoid li qub, thiab lwm yam.
Hydraulic excavators feem ntau muaj peb qhov tseem ceeb: cov cuab yeej ua haujlwm, lub cev sab saud, thiab lub cev qis. Raws li nws cov qauv thiab kev siv, nws tuaj yeem txawv rau ntau hom xws li hom kev taug qab, hom log tsheb, hom taug kev, tag nrho hydraulic, semi hydraulic, tag nrho cov teb, tsis puv teb, universal, tshwj xeeb, articulated, telescopic caj npab, thiab lwm yam.
Cov cuab yeej ua haujlwm yog ib qho khoom siv ncaj qha ua tiav cov haujlwm khawb. Nws yog hinged los ntawm peb qhov chaw: boom, stick, thiab thoob. 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 kev khawb, nqa, thauj khoom, qib, clamps, bulldozers, cuam tshuam rau hammers, rotary xyaum, thiab lwm yam cuab yeej ua haujlwm.
Lub tshuab tig thiab taug kev yog lub cev ntawm hydraulic excavator, thiab sab sauv ntawm lub turntable yog nruab nrog lub zog thiab kev sib kis. Lub cav yog lub zog ntawm hydraulic excavators, thiab diesel feem ntau yog siv. Nyob rau hauv qhov chaw yooj yim, hluav taws xob motors kuj siv tau.
Lub tshuab xa hluav taws xob hydraulic xa lub zog ntawm lub cav mus rau lub tshuab hydraulic, hydraulic lub tog raj kheej thiab lwm yam kev ua haujlwm los ntawm lub twj tso kua mis hydraulic, tsav lub tshuab ua haujlwm kom txav mus los thiab ua tiav ntau yam dej num.
