Kev Cai Ob Chav Girder Beam Portal Gantry Crane

Ob lub girder gantry crane ob lub girders tseem ceeb tau teeb tsa rau ntawm ob lub outriggers los ua ib lub gantry zoo li. Nws tsis muaj lub platform taug kev sib cais, sab saud ntawm lub girder tseem ceeb yog siv ua lub platform taug kev, thiab cov railings thiab trolley conductive carriages tau teeb tsa rau ntawm lub hau sab saud ntawm lub girder tseem ceeb. Cov platform taug kev, railings, thiab ntaiv ntawm ob lub girder gantry cranes tau tsim raws li cov cai kev nyab xeeb thiab cov qauv tsim.

Hom crane no khiav ntawm txoj kev hauv av thiab feem ntau yog siv rau kev tuav thiab teeb tsa hauv cov chaw khaws khoom qhib, chaw nres tsheb fais fab, chaw nres nkoj thiab chaw nres tsheb ciav hlau. Piv nrog cov cranes ib leeg-girder, cov cranes ob chav girder beam portal gantry cranes yog qhov tsim nyog dua rau cov haujlwm nrog ntau ntau thiab lub sijhawm tsim kho ntev. Nws txhim kho lub peev xwm tsim khoom thiab kev tsim khoom ntawm kev thauj khoom thiab tshem tawm cov haujlwm, thiab yog cov khoom siv tseem ceeb rau qhov zoo thiab kev ua haujlwm ntawm kev tsim khoom ntim khoom.

Cov gantry cranes feem ntau yog ntsia sab nraum zoov. Vim yog raug cua, nag thiab tshav ntuj ntau zaus, cov qauv tseem ceeb thiab cov khoom ntawm ob lub girder gantry crane yuav raug puas tsuaj lossis deformed vim yog corrosion, thiab cov khoom siv hluav taws xob thiab cov khoom siv tseem ceeb kuj yuav laus. Qhov no tsis tsuas yog cuam tshuam rau kev ua haujlwm zoo ntawm gantry crane, tab sis kuj tseem yuav ua rau muaj kev nyab xeeb hauv kev ua haujlwm. Yog li ntawd, nws yog qhov tsim nyog los tswj hwm lub gantry crane ntau zaus.

Qhov kev ua haujlwm ua haujlwm thiab lub neej ua haujlwm ntawm txhua lub tshuab ntawm gantry crane feem ntau nyob ntawm qhov lubrication. Ua ntej, xyuas lub hook thiab hlua hlau ntawm lub crane kom pom tias puas muaj cov xov hlau tawg, tawg thiab xeb loj, thiab ntxuav thiab roj rau lawv. Qhov thib ob, xyuas lub pulley block, nruas thiab pulley txhua hli kom paub seb puas muaj tawg, thiab seb cov bolts phaj nias thiab lub nruas puag bolts puas nruj. Thaum lub nruas ncej hnav txog li 5%, nws yuav tsum tau hloov. Thaum qhov hnav ntawm phab ntsa groove ncav cuag 8% thiab qhov hnav sab hauv ncav cuag 25% ntawm lub cheeb sab hauv ntawm cov hlua hlau, nws yuav tsum tau hloov. Tsis tas li ntawd, cov bolts ntawm lub reducer yuav tsum tau kuaj xyuas ntau zaus kom ntseeg tau tias lawv nruj.
