Cov Txheej Txheem Txhim Kho ntawm Choj Crane Choj
Cov qauv hlau ntawm tus choj crane yog lub cev pob txha ntawm lub crane, thiab tag nrho cov khoom siv hluav taws xob thiab hluav taws xob tau muab faib rau ntawm nws, uas yog cov qauv thauj khoom ntawm lub crane thiab ua rau lub crane yog ib qho khoom siv tag nrho.
Cov qauv hlau ntawm 20 tuj choj crane yog tsim los ntawm crane choj (tseem hu ua lub laub choj), trolley thav duab thiab tus neeg tsav tsheb cab.
Vim qhov kev xav tau ntawm steelmaking ntau lawm, tus choj crane yog nyob rau hauv lub xeev ntawm nquag lifting nrog tag nrho cov load rau lub sij hawm ntev, uas yuav ua rau muaj teeb meem loj xws li downward deflection thiab sab dabtsi yog khoov ntawm tus choj ncej ntawm lub crane, uas zoo heev shortens. kev pab cuam lub neej ntawm tus choj ncej, thiab tsis haum rau kev nyab xeeb ntawm lub crane. .
Yog li ntawd, nws yog ib qho tsim nyog los ntxiv dag zog rau tus choj crane choj los txhim kho cov kabmob muaj peev xwm thiab kev nyab xeeb ntawm tus choj. Hauv qab no yog ib qho kev npaj txhawb nqa rau tus choj:
Siv lub thawv-hom choj crane ua piv txwv, yog tias tus choj thav duab ntawm lub zog crane yog lub thawv-zoo li lub tsheb nqaj hlau choj ncej, kev txhim kho tag nrho cov kabmob muaj peev xwm ntawm tus choj ncej yog tsom mus rau peb feem ntawm lub ntsiab. girder, qhov txuas weld ntawm lub ntsiab girder thiab qhov kawg girder, thiab qhov kawg girder. Txhim kho qhov txaus ntshai seem, cov txheej txheem yog raws li hauv qab no:
Lub tswv yim txhawb kev txhim kho cov kabmob muaj peev xwm ntawm lub ntsiab girder
Kev nce ntawm qhov chaw hla ntawm lub ntsiab nqaj tuaj yeem ua rau lub sijhawm inertia nce ntxiv, yog li ua kom lub zog thiab nruj ntawm lub ntsiab nqaj, uas yog ib txoj hauv kev txhim khu kev qha thiab zoo los txhim kho cov kabmob ntawm lub ntsiab nqaj.
Txoj hauv kev zoo tshaj plaws los ua kom qhov chaw hla ntu ntawm girder yog raws li hauv qab no, thiab lawv cov yam ntxwv zoo li hauv qab no:
(1) Qhov sib txawv ntawm thaj tsam ntawm cov welded me me lub thawv girders yog loj, qhov loj ntawm cov khoom siv yog loj, kev ua haujlwm ntawm cov khoom siv loj, kev tsim kho yog qhov nyuaj, thiab cov khoom siv vuam yog loj. Nws yog tsim rau lub ntsiab cranes nrog loj tonnage thiab loj spans. Beam reinforcement.
(2) Qhov sib txawv ntawm thaj tsam ntawm welded channel steel reinforcement yog me dua li ntawm cov txheej txheem welded me me beam reinforcement txoj kev, thiab tus nqi ntawm cov vuam yog loj, tab sis qhov hnyav ntawm cov khoom siv ntxiv yog sib dua, kev ua haujlwm ntawm cov qauv. qhov chaw me me, thiab kev tsim kho nyuaj me me. Nws yog qhov tsim nyog rau qhov loj dua Reinforcement ntawm lub ntsiab girder ntawm crane nrog ib tug loj tonnage thiab ib tug me me ncua.
(3) Qhov sib npaug ntawm thaj tsam ntawm cov txheej txheem prestressing yog sib npaug ntawm cov txheej txheem vuam me me ntawm cov kab hluav taws xob. Tus nqi ntawm cov vuam yog me me, qhov hnyav ntawm cov khoom siv ntxiv yog lub teeb, kev ua haujlwm ntawm cov khoom siv me me, thiab kev tsim kho nyuaj me me. Nws yog tsim rau me me-tonnage cranes Lub ntsiab nqaj yog ntxiv dag zog.
