Gantry Crane yog tus choj-hom crane uas nws tus choj tau txais kev txhawb nqa ntawm cov hauv av taug kev ntawm cov neeg sawv cev ntawm ob sab. Kev tsim qauv, nws muaj cov mast, trolley kev ua haujlwm ua haujlwm, qhov chaw trolley thiab hluav taws xob. Ib co gantry cranes tsuas yog muaj cov neeg nyob ntawm ib sab, thiab lwm sab yog txhawb nqa ntawm lub tsev tsim lossis trestle, uas yog hu ua aSemi-Gantry CraneCov. Lub gantry crane yog tsim los ntawm cov nqaj qaum (xws li nqaj loj thiab kawg nqaj), cov nqaj, qis dua nqaj thiab lwm qhov chaw. Txhawm rau nthuav cov crane cov haujlwm ua haujlwm, lub nqaj tseem ceeb tuaj yeem txuas ntxiv dhau ntawm cov tsis muaj peev xwm rau ib lossis ob tog los ua ib tug cantilever. Ib lub trolley nrog lub boom kuj tseem siv tau los nthuav cov crane kev ua haujlwm dhau los ntawm pitching thiab kev sib hloov ntawm lub boom.
1. Daim ntawv foos
Gantry Cranestuaj yeem raug cais raws li cov qauv ntawm lub qhov rooj thav duab, daim ntawv ntawm lub nqaj loj, tus qauv ntawm lub nqaj loj, thiab daim ntawv siv.
a. Qhov Rooj Ncej Qauv
1. Tag nrho Gantry Crane: lub nqaj tseem muaj tsis muaj overhang, thiab cov trolley txav nyob rau hauv lub ntsiab lus tseem ceeb;
2. Semi-Gantry Crane: Cov neeg tsim tawm muaj qhov txawv, uas tuaj yeem txiav txim siab raws li cov neeg contactive uas yuav tsum tau ua raws li cov chaw ua haujlwm.
b. Cantilever Gantry Crane
1. Ob leeg cantilever gantry crane: feem ntau cov qauv qauv, kev ntxhov siab ntawm cov qauv thiab kev siv zoo ntawm thaj chaw yog tsim nyog.
2. Ib Cantilever Gantry Crane: Cov qauv qauv no feem ntau xaiv vim yog qhov kev txwv site.
c. Lub ntsiab Beam Daim Ntawv
1. Insingle lub nqaj loj
Ib qho loj girder gantry crane muaj cov qauv yooj yim, yog qhov yooj yim rau kev tsim thiab nruab, thiab muaj ib pawg me me. Cov Girder loj feem ntau yog deflection lub thawv qauv qauv. Piv nrog ob lub ntsiab loj girder gantry crane, tag nrho cov tawv nqaij tawv tag nrho yog tsis muaj zog. Yog li, daim foos no tuaj yeem siv thaum lub sijhawm nqa tau lr ≤00t thiab SPAN S≤35M. Tib Girder Gantry Crane Ceg ob tog muaj nyob hauv L-hom thiab C-hom. L-hom yog yooj yim rau kev tsim thiab nruab, muaj kev ntxhov siab tsis kam, thiab muaj ib pawg me. Txawm li cas los xij, qhov chaw rau kev nqa cov khoom kom hla dhau ntawm txhais ceg yog qhov me me. C-puab ob txhais ceg yog ua nyob rau hauv ib qho kev xav lossis nkhaus los tsim cov chaw tom qab loj dua kom cov khoom lag luam tuaj yeem hla dhau ntawm txhais ceg kom dhau.
2. Ob chav lub ntsiab lub nqaj
Ob chav loj girder gantry cranes muaj cov muaj zog tsim muaj peev xwm, loj loj, zoo zuag qhia tag nrho, thiab ntau ntau yam. Txawm li cas los xij, piv nrog ib qho loj girder gantry cranes nrog tib lub peev xwm uas muaj peev xwm loj dua, lawv tus kheej loj dua thiab tus nqi siab dua. Raws li cov chaw sib txawv ntawm ko taw kev sib txawv, nws tuaj yeem faib ua ob hom: Box nqaj thiab truss. Feem ntau, lub thawv ntawv zoo li qub tau siv.
d. Main Beam Tsim
1.truss nqaj
Cov qauv tsim welded los ntawm lub kaum sab xis steel lossis I-nqaj muaj qhov zoo ntawm tus nqi qis, lub teeb yuag thiab cov cua tsis zoo. Txawm li cas los xij, vim muaj ntau tus neeg siv vuam thiab qhov tsis xws luag, tsis muaj qhov tsis txaus ntseeg, thiab qhov kev xav tau tsawg ntawm cov ntsiab lus vuam. Nws yog qhov tsim nyog rau cov chaw nrog kev nyab xeeb kom muaj kev nyab xeeb thiab kev nqa khoom me me.
2. Thawv Hlais
Cov phiaj hlau hlau yog welded rau hauv lub thawv qauv, uas muaj cov yam ntxwv ntawm kev nyab xeeb thiab siab tawv. Feem ntau siv rau loj-tonnage thiab ultra-loj-tonnage gantry cranes. Raws li muaj nyob hauv daim duab nyob sab xis, mghz1200 muaj lub peev xwm ntawm 1,200 tons. Nws yog qhov loj tshaj plaws gantry crane hauv Suav teb. Lub ntsiab ntawm lub ntsiab saws lub thawv girder. Lub thawv teeb tseem muaj qhov tsis zoo ntawm cov nqi siab, hnyav hnyav, thiab cua tsis zoo.
3.Heysomb nqaj
Feem ntau xa mus rau raws li "isosceles daim duab peb sab honeycomb nqaj", kawg ntawm lub nqaj yog voos, muaj chords, thiab muaj chords, thiab muaj chords nyob rau sab saud thiab qis dua. Honeycomb cov kab teeb ntxig nqus cov yam ntxwv ntawm cov nqaj truss thiab lub thawv ci. Piv nrog cov nqaj truss, lawv muaj qhov sib zog ntau dua, kev tiv thaiv me, thiab kev ntseeg tau ntau dua. Txawm li cas los xij, vim kev siv ntawm cov hlau phaj vuam, qhov hnyav tus kheej thiab cov nqi siab dua me ntsis siab dua li ntawm cov nqaj truss. Nws yog qhov haum rau cov chaw lossis cov nqaj ci nrog siv ntau lossis hnyav ntxiv. Txij li no nqaj hom yog cov khoom muaj patented, muaj cov chaw tsim khoom tsawg.
2. Cov ntawv siv siv
1. Ach dog dig gantry crane
2.Hydropower chaw nres tsheb gantry crane
Nws yog tsuas yog siv rau kev nqa, qhib thiab kaw rooj vag, thiab tseem siv tau rau kev teeb tsa kev teeb tsa. Lub peev txheej tau txais 80 rau 500 tons, lub tons yog me me, 8 txog 16 metres, thiab nqa tawm yog tsawg, 1 txog 5 meters / min. Txawm hais tias hom crane no tsis nquag nqa, kev ua haujlwm hnyav heev thaum nws tau siv, yog li qib ua haujlwm yuav tsum tau nce ntxiv.
3. Lub nkoj nkoj Gantry Crane
Siv los sib dhos rau lub hull ntawm cov khau khiab ib txwm muaj: ib qho muaj ob lub ntsiab lus tseem ceeb, khiav ntawm txoj kev ntawm tus choj sab saud; Lwm tus muaj lub xov tooj tseem ceeb thiab ib tus lookiliary nuv, rau ntawm flange flange ntawm tus choj. Khiav ntawm ntsia rov qab thiab nqa cov ntu hall loj me. Lub peev xwm nqa yog feem ntau 100 rau 1500 tons; Cov lus luv yog txog li 185 metres; Txoj kev nqa ceev yog 2 txog 15 metres / min, thiab muaj ib lub micro txav ceev ntawm 0.1 txog 0.5 meters / min.
3. Txoj Haujlwm
Gantry Crane kuj yog qib ua haujlwm ib ntawm Gantry Crane: nws qhia txog cov yam ntxwv ua haujlwm ntawm crane nyob rau hauv cov nqe lus ntawm kev thauj khoom thiab khoom tsis khoom.
Qhov kev faib cov qib ua haujlwm tau txiav txim siab los ntawm Crane siv qib siv U thiab thauj cov xwm txheej Q. Lawv tau muab faib ua AR1 rau A8.
Qib ua haujlwm ntawm lub crane, uas yog, theem ua haujlwm ntawm cov qauv hlau, yog txiav txim siab raws li txoj kev nqa lub tshuab thiab muab faib ua theem A1-A8. Yog hais tias piv nrog hom haujlwm ua haujlwm ntawm cranes teev nyob rau hauv Suav teb, nws yog kwv yees sib npaug rau: A1-A4-lub teeb; A5-A6- Nruab Nrab; A7-Hnyav, A8-EXIT HEEV.
