Makonda Awiri Girder Beam Portal Gantry Crane

Zotchingira ziwiri zazikulu za girder gantry crane zimayikidwa pazingwe ziwiri kuti apange mawonekedwe a gantry. Zilibe malo oyenda osiyana, gawo lapamwamba la girder lalikulu limagwiritsidwa ntchito ngati nsanja yoyendayenda, ndipo njanji ndi ma trolley conductive carriage amaikidwa pachivundikiro chapamwamba cha girder yaikulu. Mapulatifomu oyenda, njanji, ndi makwerero a double girder gantry cranes amapangidwa motsatira malamulo okhudzana ndi chitetezo ndi kapangidwe kake.

Crane yamtunduwu imayendera pansi ndipo imagwiritsidwa ntchito kwambiri pogwira ndi kuyikapo ntchito m'mabwalo osungira otseguka, malo opangira magetsi, madoko ndi malo onyamula katundu wa njanji. Poyerekeza ndi ma cranes a single-girder gantry cranes, ma cranes opangidwa ndi girder beam portal gantry ndioyenera projekiti yokhala ndi kuchuluka kwakukulu komanso nthawi yayitali yomanga. Imawongolera kwambiri mphamvu zopangira ndi zokolola zonyamula ndi kutsitsa, ndipo ndiye zida zonyamulira zabwino komanso zogwira mtima pakumanga.

Ma crane a Gantry amayikidwa panja. Chifukwa cha kukhudzidwa pafupipafupi ndi mphepo, mvula ndi kuwala kwa dzuwa, kapangidwe kake ndi zigawo za double girder gantry crane zidzawonongeka kapena kupunduka chifukwa cha dzimbiri, komanso zida zamagetsi ndi zida zomwe zimayenera kukalamba. Izi sizimangokhudza magwiridwe antchito a gantry crane, komanso zingayambitse ngozi zachitetezo pantchito. Chifukwa chake, ndikofunikira kusamalira gantry crane pafupipafupi.

Kugwira ntchito ndi moyo wautumiki wa makina aliwonse a gantry crane makamaka zimadalira mafuta. Choyamba, yang'anani mbeza ndi chingwe chawaya cha crane kuti muwone ngati pali mawaya othyoka, ming'alu ndi dzimbiri lalikulu, ndikuyeretsani ndikuzipaka mafuta. Kachiwiri, yang'anani chipika cha pulley, ng'oma ndi pulley mwezi uliwonse kuti muwone ngati pali ming'alu, komanso ngati mabawuti a mbale ndi mabawuti a ng'oma alimba. Pamene shaft ya ng'oma yavala pafupifupi 5%, iyenera kusinthidwa. Pamene kuvala kwa khoma la groove kufika pa 8% ndipo kuvala kwamkati kufika pa 25% ya mkati mwa chingwe cha waya, chiyenera kusinthidwa. Kuonjezera apo, ma bolts a reducer ayenera kufufuzidwa pafupipafupi kuti atsimikizire kuti akumizidwa.
