Kev tsim qauv tshwj xeeb tso tawm gantry crane rau kev tsim kho choj

Lub launching girder gantry crane, lub tshuab nqa khoom muaj zog thiab ntau yam, tau dhau los ua ib qho cuab yeej tseem ceeb hauv kev lag luam kev tsim kho. Nws lub hom phiaj tseem ceeb yog los pab hauv kev tsim kho thiabkev teeb tsa cov choj, viaducts, thiab cov kev loj siab. Lub crane no ua lub luag haujlwm tseem ceeb hauv kev nqa cov khoom siv hnyav, xws li cov girders ua los ntawm cov pob zeb precast, thiab muab tso rau hauv lawv qhov chaw tshwj xeeb.

Tam sim no, cia peb kawm txog cov yam ntxwv ntawm lub crane launching girder gantry crane uas ua rau lub crane no tshwj xeeb hauv kev tsim kho. Lub hauv paus ntawm lub crane no yog lub cev muaj zog uas muab kev ruaj khov thiab kev txhawb nqa thaum lub sijhawm nqa khoom. Lub cev no feem ntau yog ua los ntawm cov hlau zoo, ua kom muaj zog thiab ruaj khov tshaj plaws. Nws muaj cov kem ntsug, cov girders kab rov tav, thiab cov bracing diagonal, txhua yam tau tsim los kom tiv taus cov khoom hnyav thiab tswj kev ruaj khov hauv qab cov xwm txheej tsis zoo.

Ib qho ntawm cov yam ntxwv tseem ceeb ntawm lub launching girder gantry crane yog nws cov kev hloov kho tau. Cov kev no, nyob rau ob sab ntawm lub crane, tso cai rau kev txav mus los yooj yim raws qhov chaw tsim kho. Nrog lub peev xwm los nthuav lossis rub rov qab, lub crane tuaj yeem hloov kho rau ntau qhov txuas ntawm tus choj, kom ntseeg tau tias qhov chaw zoo tshaj plaws thaum lub sijhawm tsa. Qhov kev hloov kho no yog qhov tseem ceeb tshwj xeeb tshaj yog thaum ua tiav cov haujlwm tsim kho nyuaj nrog ntau yam geometries.

Txhawm rau txhawb nqa kev ua haujlwm nqa, lub crane siv ntau lub tshuab nqa. Lub tshuab nqa tseem ceeb feem ntau yog lub tshuab hydraulic jack, uas muab lub zog xav tau los tsa cov khoom hnyav precast. Cov jacks no tau muab tso rau ntawm lub girder tseem ceeb, ua rau muaj kev faib khoom sib npaug thaum lub sijhawm nqa. Tsis tas li ntawd, lub crane muaj cov tshuab pabcuam xws li outriggers thiab stabilizers, uas txhim kho kev ruaj khov thiab txo qis kev co lossis tilting uas yuav tshwm sim thaum lub sijhawm nqa.

Kev nyab xeeb yog qhov tseem ceeb tshaj plaws hauv txhua qhov project tsim kho, thiab lub launching girder gantry crane kuj tsis muaj qhov tshwj xeeb. Yog li, nws muaj ntau yam kev nyab xeeb. Cov no suav nrog cov khawm txwv, cov nyees khawm nres thaum muaj xwm txheej ceev, thiab cov tshuab tiv thaiv kev thauj khoom ntau dhau. Cov kev ntsuas no ua kom ntseeg tau tias lub crane ua haujlwm hauv nws lub peev xwm teev tseg thiab tiv thaiv txhua qhov xwm txheej lossis kev puas tsuaj vim kev thauj khoom ntau dhau. Ntxiv mus, lub crane tau tsim nrog cov khoom siv tiv thaiv kev ntxeev thiab cov ntsuas cua ceev los tswj cov huab cua tsis zoo, ntxiv kom ntseeg tau tias muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab qhov chaw tsim kho.
