Crane Yopangidwa Mwamakonda Yokhala ndi Ma Girder Beam Portal Gantry

Ma girders awiri akuluakulu a double girder gantry crane amayikidwa pa outriggers ziwiri kuti apange mawonekedwe a gantry. Alibe nsanja yosiyana yoyendera, gawo lapamwamba la girder lalikulu limagwiritsidwa ntchito ngati nsanja yoyendera, ndipo ma railings ndi ma trolley conductive carriages amayikidwa pamwamba pa girder yayikulu. Mapulatifomu oyendera, ma railings, ndi makwerero a double girder gantry crane amapangidwa motsatira malamulo oyenera achitetezo ndi mafotokozedwe a kapangidwe.

Mtundu uwu wa crane umayenda panjira yapansi ndipo umagwiritsidwa ntchito makamaka pokonza ndi kukhazikitsa malo osungiramo zinthu, malo opangira magetsi, madoko ndi malo osungira katundu a sitima. Poyerekeza ndi ma crane a gantry okhala ndi girder imodzi, ma crane a gantry opangidwa mwamakonda okhala ndi girder beam portal gantry ndi oyenera kwambiri mapulojekiti okhala ndi nthawi yayitali yomanga. Amakweza kwambiri mphamvu yopanga ndi kupanga bwino ntchito zonyamula ndi kutsitsa katundu, ndipo ndiye chida chofunikira kwambiri chonyamulira zinthu paubwino ndi magwiridwe antchito omanga ma paketi.

Ma crane a gantry amayikidwa panja. Chifukwa cha mphepo, mvula ndi kuwala kwa dzuwa pafupipafupi, kapangidwe kake ndi zigawo za double girder gantry crane zidzawonongeka kapena kusokonekera chifukwa cha dzimbiri, ndipo zida zamagetsi ndi zida zina zidzakalamba mosavuta. Izi sizimangokhudza kugwira ntchito bwino kwa gantry crane, komanso zingayambitse ngozi zachitetezo pantchito. Chifukwa chake, ndikofunikira kusamalira gantry crane pafupipafupi.

Kagwiridwe ka ntchito ndi moyo wa ntchito ya makina aliwonse a gantry crane zimadalira kwambiri mafuta. Choyamba, yang'anani chingwe cha mbedza ndi waya cha crane kuti muwone ngati pali mawaya osweka, ming'alu ndi dzimbiri lalikulu, ndikuyeretsa ndi kuzipaka mafuta. Kachiwiri, yang'anani pulley block, drum ndi pulley mwezi uliwonse kuti mudziwe ngati pali ming'alu, komanso ngati ma bolts a pressing plate ndi ma bolts a dram base amangidwa. Pamene shaft ya drum yavala pafupifupi 5%, iyenera kusinthidwa. Pamene groove wall groove closure closure ifika 8% ndipo intraintial closure ifika 25% ya inner diameter ya waya, iyenera kusinthidwa. Kuphatikiza apo, ma bolts a reducer ayenera kufufuzidwa pafupipafupi kuti atsimikizire kuti amangidwa.
