Taug qab khau qauv thiab siv
The manufacturer of the track shoe chassis will give you a detailed explanation, where to buy the track chassis, welcome to inquire email: hongda04@qzhdm.com and tel no.:+86 15359562153 Fujian Jinjia Machinery Co., Ltd. The track chassis is affordable, quality assurance, and various types of OEMs.
Cov khau khiav yog ib qho ntawm cov chassis ntawm kev tsim kho tshuab, thiab yog ib feem ntawm kev siv tshuab siv.Feem ntau siv rau hauv excavators, bulldozers, crawler cranes, pavers thiab lwm yam kev siv tshuab.
Cov qauv ntawm cov khau khiav
Feem ntau siv cov khau taug qab tau muab faib ua peb hom raws li cov duab hauv av, suav nrog ib leeg tav, peb tav thiab tiaj hauv qab, thiab qee qhov kuj siv cov khau khiab.Cov khau khiab ib leeg yog siv rau cov bulldozers thiab tsheb laij teb, vim tias cov khau khiav yuav tsum muaj peev xwm traction siab thaum lub tshuab ua haujlwm.Txawm li cas los xij, nws tsis tshua siv rau ntawm excavators.Hom khau no tsuas yog siv thaum lub laum thav duab raug ntsia rau ntawm lub tshuab excavator lossis thaum xav tau txoj kab rov tav loj.High traction quab yuam yog yuav tsum tau thaum tig los ntawm lub sub, yog li cov tread bars siab dua (piv txwv li stabs) yuav nyem cov av (los yog hauv av) ntawm cov tread tuav, yog li cuam tshuam rau kev txav ntawm lub excavator.
Hlau taug kev khau tuaj yeem muab faib ua: khau excavator, khau khau khau, ob qho no feem ntau siv, nrog cov hlau ua raw khoom.Tom qab ntawd muaj cov av ntub dej siv los ntawm lub tsheb nrau av, feem ntau hu ua "daim duab peb sab", uas yog lub phaj cam khwb cia.Lwm hom cam khwb cia yog siv rau crawler cranes.Qhov hnyav ntawm lub phaj no tuaj yeem nyob ntawm kaum ntawm kilograms mus rau pua pua kilograms.
Kev siv cov khau khiav
Feem ntau cov excavators siv peb-rib taug qab khau, thiab ob peb siv cov khau tiaj-hauv qab.Thaum tsim cov khau peb-rib taug kev, ua ntej, lub hauv paus tshwj xeeb siab thiab meshing av muaj peev xwm nruab nrab ntawm txoj kab khiav thiab hauv av yuav tsum tau ua kom muaj qhov tsim nyog adhesion;Thib ob, cov khau khiav yuav tsum muaj lub zog flexural siab thiab hnav tsis kam.Cov khau peb-rib feem ntau muaj ob qhov av nkos tshem tawm.Thaum cov khau khiav tig ib ncig ntawm lub log tsav, cov av nkos ntawm cov saw txuas tuaj yeem raug tshem tawm los ntawm cov iav hniav, yog li cov av tshem tawm qhov yuav tsum nyob nruab nrab ntawm ob lub qhov ntsia hlau uas kho cov khau khiav ntawm cov saw txuas.
Txhawm rau tiv thaiv cov av saum npoo av thiab txo qhov kev hloov pauv ntawm cov cuab yeej siv taug kev siv hauv cov hav dej los yog ua liaj ua teb, nws yog qhov tsim nyog los siv cov crawler txuas ntxiv thiab lub tiaj tus hauv qab crawler [1].Txhawm rau kom ntseeg tau tias thaum cov saw hlau crawler nyob rau hauv txhua txoj haujlwm (xws li hauv av, tig ib ncig ntawm lub log tsav tsheb thiab lub log tsheb, thiab txoj haujlwm raug ncua), lub pob zeb yuav tsis raug ntes ntawm ob sab ntawm cov khau crawler thiab ua rau muaj kev ntxhov siab ntau dhau.Qhov kev ncua deb yog kho kom raug thiab daim di ncauj ntawm lub ntsej muag tsim nyog yuav tsum tau tsim.Lub luag haujlwm ntawm lub puab tsaig di ncauj yog ua kom cov taug qab khau abut tiv thaiv ib leeg, tsim ib txoj siv sia uas txuas mus rau qhov kawg.
Cov khau khiav yuav tsum tau muab tso rau hauv ib qho kev taw qhia.Lub suab me me ntawm txoj kev khiav, qhov me dua qhov nce ntawm cov saw hlau thaum nws khiav ntawm lub log tsav thiab lub log tsheb.Nyob rau hauv txoj kev no, kev sib tw khiav yog qhov zoo, qhov hnav ntawm crawler saw yog qhov tsawg, thiab kev tsav tsheb ua haujlwm siab thaum taug kev.Txawm li cas los xij, qhov tsawg kawg nkaus tus nqi yuav tsum tau txiav txim siab raws li lub tshuab hnyav thiab tus naj npawb ntawm cov kab ntawm cov saw crawler.Feem ntau, qhov sib nrug ntawm ob kab ntawm cov hlua hlua uas cov khau taug qab tau teeb tsa yuav tsum loj dua, yog li cov khau khiav nrog qhov sib txawv hauv av tshwj xeeb tuaj yeem hloov tau.Cov cuab yeej taug kev siv hauv cov hav dej xav tau cov khau dav dav thiab taug qab qhov chaw, thiab cov khau ultra-wide taug qab qee zaum muaj kev ntxhov siab siab.
Piv txwv li, thaum lub excavator ua hauj lwm nyob rau hauv av tov nrog residual tsob ntoo cov hauv paus hniav, ib feem ntawm lub tshuab hnyav poob rau ntawm ib tug khiav khau txhawb los ntawm cov ntoo hauv paus, yog li ntawd cov khiav khau muaj ib tug heev bending kev nyuaj siab, uas muaj feem xyuam rau txoj kev khiav.lub neej ntawm lub rooj tsavxwm.Txhawm rau tiv thaiv kev puas tsuaj thiab khoov ntawm cov khau khiav, ntu coefficient thiab khoov lub zog yuav tsum tau nce ntxiv.Txhawm rau ua kom cov seem coefficient, nws yog ib qho tsim nyog yuav tsum tau ua kom qhov siab ntawm cov tread tuav, tab sis qhov no yuav ua rau kom muaj zog tig thiab cuam tshuam rau kev txav ntawm lub excavator.
Yog li ntawd, steel dov hollow taug qab khau yuav tsum tau siv rau kev taug kev cov khoom siv nrog qhov dav ntawm ntau tshaj 700 hli rau swamps.Feem ntau ntawm ob qhov kawg ntawm txoj kev taug kev khau siv nyob rau hauv swamps yog ua los ntawm txoj kab nqes, uas yog yooj yim los tiv thaiv hauv av nto, txo txoj kev tig tsis kam thiab kev poob qis, thiab thaum taug kev hauv av nyuaj, qhov luv ntawm lub caj npab txhawb nqa tuaj yeem txo qhov kev sib hloov ntawm cov khoom siv. khoov lub sij hawm nqa los ntawm ntug..
Excavators nrog ib tug khiav khau dav tshaj 800 mm yog tsuas yog siv nyob rau hauv swamps thiab yuav tsum tsis txhob siv nyob rau hauv feem ntau zaus.Lub excavator nrog widened thiab txuas ntxiv crawler taug kev ntaus ntawv yog tshwj xeeb tshaj yog haum rau pipeline engineering.
