Cov kab txiav hlav tuaj yeem muab cais tawm raws li daim ntawv ntawm lub qhov rooj, raws li daim ntawv loj beam, raws li lub ntsiab nqaj hlau, raws li daim ntawv siv.

Doorframe qauv

Nws tau muab faib ua txoj kab txiav crane thiab cov chaw pov tseg ntawm txoj cai

Portal crane

1. tag nrho cov qhov rooj crane: lub tsaj beam tseem ceeb tsis raug ncua, thiab lub tsheb yog nqa tawm hauv lub ntsiab luv.

2. ib nrab qhov rooj crane: tus ceg muaj qhov siab thiab qis qis, uas tuaj yeem txiav txim siab raws li kev sam fwm ntawm lub tsev kawm ntawv.

Cantilever gantry crane

1. ob tog ntiv tes hloov chaw pov npav: feem ntau hom kev teeb tsa ntawm tus qauv, lub zog ntawm nws cov qauv thiab kev siv ntawm thaj chaw hauv thaj chaw yog qhov tsim nyog.

2. ib leeg txiav txim siab gantry crane: hom qauv no feem ntau xaiv vim qhov kev txwv ntawm qhov chaw.

Daim nqaj daim npluag loj

1. ib lub ntsiab nqaj

Tib lub nya hau gantry crane muaj qhov zoo ntawm cov qauv yooj yim, yooj yim tsim thiab installation, nws zoo yog me me, ib nrab tsheb thawv thooj qauv. Piv nrog rau ob npaug ntawm kab laug sab hauv lub crane, tag nrho txoj kev sib zog yog weaker. Yog li, thaum twg qhov nyhav yog Q = 50t, S = 35m, yuav siv daim ntawv no. L hom thiab C hom ob hom ntawm cov nyom ntawm cov lauj kaub rau hauv kauj ruam. Cov kev tsim thiab kev tsim ntawm hom L yog yooj yim, qhov kev quab yuam yog qhov zoo, thiab nws tus kheej zoo me me, tab sis qhov chaw ntawm cov khoom nqa tawm los ntawm cov ceg yog tsawg. Kev txhawb ntawm hom C yog inclined los yog nkhaus, nrog lub hom phiaj ntawm qhov muaj qhov chaw loj transverse chaw ua kom cov khoom dhau los ntawm ko taw nkaws.

2. ob chav ntsiab nqaj

Ob chav girder gantry crane span, muaj zog bearing peev, zoo zuag qhia tag nrho, tab sis nws zoo thiab ntau yam, tib yam li tus kheej girder gantry crane luj piv rau tus nqi siab dua. Raws li lub qauv ntawm lub ntsiab beam, nws muaj peev xwm muab faib ua ob hom, lub thawv nkag thiab truss. Feem ntau, lub thawv ntawv feem ntau yog siv.

Lub ntsiab nqaj nqaj

1. Tsiaj txhu tras

Cov qauv ntawm lub kaum sab xis steel lossis I-steel welding muaj qhov zoo ntawm tus nqi qis, lub teeb nws tus kheej hnyav thiab qhov cua tsis zoo. Txawm li cas los xij, vim tsis muaj cov ntsiab lus vuam thiab cov defects ntawm lub truss, tus nqaj hlau trussed tseem muaj qhov tsis zoo ntawm cov deflection loj, me rigidity, tsis tshua muaj kev ntseeg tau thiab nquag nrhiav ntawm cov kab laug sab pob txha. Nws yog tsim rau lub tsev kawm ntawv uas tsis muaj kev nyab xeeb thiab tsis hnyav dua.

2. lub thawv ntawv sau

Kev siv welded steel lub thawv hom qauv, muaj qhov zoo ntawm kev ruaj ntseg zoo, rigidity etc .. Feem ntau siv rau cov tonnage loj thiab ultra loj tonnage gantry cranes. Piv txwv, txoj cai MGhz1200, nrog rau ib qhov hnyav ntawm 1200 tons, yog qhov loj tshaj plaws hauv lub crane nyob hauv lub teb chaws, thiab lub girder txais lub npov ntawm cov ntawv nkag teb chaws. Lub thawv ntawv tseem muaj qhov tsis zoo ntawm tus nqi them, tus kheej tseem ceeb thiab tsis muaj zog cua tsis kam.

3. Tsiaj txhu nqaj

Feem ntau, nws yog hais txog "isosceles triangular beehive beams", qhov kawg ntawm lub ntsiab nqaj yog qhov sib luag, thiab muaj cov qhov muaj me honeycomb qhov ntawm ob sab ntawm oblique plab thiab lub pob thiab qis dua. Honeycomb beams nqus cov yam ntxwv ntawm truss kab laum thiab lub thawv kab, uas muaj zog loj, me me deflection thiab ntau dua kev ntseeg tau tshaj li truss kab. Tab sis vim txoj kev siv steel phuam welding, qhov nyhav thiab tus nqi ntawm kev sib tsoo truss Shaogao. Nws yog tsim rau qhov chaw los yog txoj kab nqaj uas yog siv los sis nrog hnyav loj. Vim hais tias cov nqaj yog ib yam khoom muaj nqis, cov khw tsim muaj tsawg.
