Daim Ntawv Thov Tshiab thiab Tsim Cov Ntsiab Lus Tseem Ceeb ntawm Crane Girders Ua Haujlwm Zoo Li Rigid Tie Rods hauv Lub Teeb HlauCov qauv
Qhov zoo ntawm kev sib koom ua ke Crane Girders nrog Rigid Tie Rods
Lub teeb steel qauv tau siv dav hauv kev tsim kho niaj hnub vim lawv qhov tshwj xeeb zoo. Lub ingenious kev koom ua ke ntawm crane girders thiab nruj khi rods ntxiv txhim khu kev ua tau zoo ntawm lub teeb steel qauv. Qhov kev tsim no tsis tsuas yog txuag cov ntaub ntawv thiab txo cov qauv ntawm tus kheej- qhov hnyav, tab sis kuj tseem txhim kho kev ruaj ntseg ntawm tus qauv. Hauv loj -cov nroj tsuag loj, warehouses thiab lwm qhov chaw, daim ntawv thov kev koom ua ke no tau dhau los ua ib qho tseem ceeb hauv tsev. Nyob rau hauv lub portal rigid thav duab teeb - hnyav lub tsev steel qauv, crane girders yuav siv tau raws li ib tug lwm txoj rau dais lub luag hauj lwm ntawm nruj khi rods, tab sis lawv yuav tsum tau raws li tej yam kev cai tsim.
Tsim thiab Daim Ntawv Thov Cov Ntsiab Lus
A. Yuav tsum tau txaus siab nyob rau hauv Crane Girder Design
ib. Qhov ntsuas hluav taws kub tsis zoo ntawm crane girders yuav tsum ua raws li cov kev sib tshuam ntawm -kem bracings.
b. Thaum xam cov crane girders, axial quab yuam los ntawm lawv raws li nruj khi rods yuav tsum raug coj mus rau hauv tus account.
c. Txhawm rau tiv thaiv cov teeb meem kev txhawb nqa los ntawm qhov ua tau tsis zoo ntawm cov pob qij txha, xws li kev txhais lus lossis torsion ntawm cov khoom txhawb nqa, lub kaum sab xis ntxiv yuav tsum tau nruab rau kev kho.
d. Kev tsim cov pob qij txha txhawb nqa yuav tsum ua tau raws li cov qauv tsim nyog rau kev tiv thaiv axial quab yuam.
Lub tswv yim tsim ntawm kev siv crane girders raws li longitudinal rigid khi rods tsis yog tsuas yog kev lag luam, tab sis kuj yog ib qho kev xaiv uas xav tau vim yog tus ntoo khaub lig loj -section thiab zoo rigidity ntawm crane girders lawv tus kheej. Txawm li cas los xij, thaum lub sijhawm ua haujlwm, cov teeb meem tseem ceeb saum toj no yuav tsum tau them nyiaj rau, txhawm rau kom ntseeg tau tias muaj kev nyab xeeb thiab kev nyab xeeb ntawm kev tsim.
B. Kev ntsuas tseem ceeb rau Crane Girders los ua haujlwm raws li Rigid Tie Rods
ib. Nyob rau hauv lub teeb steel qauv, corbels ntawm crane girders feem ntau yog tsim los ua cantilever beams siv crane girders raws li nruj khi pas nrig. Rau sab kab, txawm li cas los xij, vim muaj qee qhov kev ncua deb ntawm lub crane girder thiab sab hauv nruab nrab, nws tuaj yeem tsuas yog muab kev txhawb nqa rau sab hauv flange ntawm kem, tab sis tsis yog rau sab nrauv flange. Tsis tas li ntawd, lub longitudinal braking quab yuam thiab transverse kab rov tav quab yuam ntawm lub crane yuav tsim lateral dabtsi yog khoov lub sij hawm ntawm lub cantilever corbels, uas nyob rau hauv lem impose ntxiv torsion nyob rau hauv txhua. Yog li ntawd, txhawm rau txhim kho cov txiaj ntsig kev txhawb nqa, lub kaum sab xis yuav tsum tau teem rau ntawm lub flange sab sauv ntawm lub crane girder thiab txuas nrog lub flange sab nraud ntawm kem. Nws yog ib qho tsim nyog los xyuas kom meej tias ob qhov kawg ntawm txhua lub crane girder yog nruab nrog lub kaum sab xis kom ua tiav ob sab kev txhawb nqa rau kem.
b. Rau nruab nrab kab kab nrog crane girders teem rau ntawm ob sab, nws raug nquahu kom nruab ob sab lub kaum sab xis ntawm cov kab no txhawm rau txhim kho qhov nruj ntawm cov crane girders. Nyob rau hauv cov ntaub ntawv no, lub kaum sab xis braces yuav hla ib leeg, tab sis los ntawm ingenious tsim, ob tug hla lub kaum sab xis braces tuaj yeem txuas rau sab sauv thiab sab saum toj ntawm lub flange ntawm lub crane girder raws li. Lub caij no, stiffeners yuav tsum tau teem rau ntawm txhua kab los ua cov ntawv txuas rau lub kaum sab xis, thiab lawv cov tuab tuaj yeem ua tau raws li cov crane girder flange los pab txhawb kev sib txuas ntawm lub kaum sab xis.
c. Yog hais tias lub crane girder ntawm qhov kawg ncua tsis tau tsim raws li ib tug cantilever qauv, nruj khi rods yuav tsum tau teem nyob rau hauv lub kawg ncua los xyuas kom meej cov qauv stability.
d. Kev saib xyuas tshwj xeeb yuav tsum tau them rau qhov tseeb tias crane girders feem ntau yog ntsia rau hauv theem tom ntej kev tsim kho. Thaum lub crane girders tsis tau ntsia thaum lub sij hawm tsim kho, cov kev ntsuas yuav tsum tau coj los xyuas kom meej cov qauv stability. Tsis tas li ntawd, rau cov nroj tsuag nrog tshwj xeeb crane txoj haujlwm lossis qhov chaw crane girders tsis tau nruab rau lub sijhawm ntev, cov hlua khi ruaj khov tseem yuav tsum tau npaj kom muaj kev nyab xeeb thiab ruaj khov ntawm cov qauv.
