Crane ya mlatho ndi mtundu wa crane womwe umagwiritsidwa ntchito m'mafakitale. Kireni yam'mwamba imakhala ndi njira zowulukiramo zofananira zokhala ndi mlatho wodutsa pakati pake. Chokwera, chigawo chokweza cha crane, chimayenda m'mbali mwa mlatho. Mosiyana ndi ma cranes oyenda kapena omanga, ma cranes apamwamba amagwiritsidwa ntchito popanga kapena kukonza pomwe kuchita bwino kapena kutsika kumakhala chinthu chofunikira kwambiri. Zotsatirazi zikuwonetsa njira zina zotetezeka zama crane apamtunda.
(1) Zofunikira zonse
Ogwira ntchito ayenera kupititsa mayeso a maphunziro ndikupeza satifiketi ya "gantry crane driver" (code-wotchedwa Q4) asanayambe kugwira ntchito (oyendetsa makina oyendetsa makina ndi oyendetsa kutali safunikira kuti apeze satifiketi iyi ndipo adzaphunzitsidwa ndi gululo. ). Wogwiritsa ntchitoyo ayenera kudziwa bwino momwe crane imagwirira ntchito ndipo ayenera kutsatira mosamalitsa malamulo achitetezo. Ndizoletsedwa kwa odwala omwe ali ndi matenda a mtima, odwala omwe ali ndi mantha okwera, odwala omwe ali ndi kuthamanga kwa magazi, komanso odwala zolaula kuti azigwira ntchito. Oyendetsa ntchito ayenera kupuma bwino komanso zovala zoyera. Ndizoletsedwa kuvala ma slippers kapena kugwira ntchito opanda nsapato. Ndikoletsedwa kwambiri kugwira ntchito mutamwa mowa kapena mutatopa. Ndizoletsedwa kuyankha ndikuyimba mafoni pafoni kapena kusewera masewera mukamagwira ntchito.
(2) Malo ogwirira ntchito
Ntchito mlingo A5; kutentha kozungulira 0-400C; chinyezi chachibale osati 85%; osayenerera malo okhala ndi mpweya wowononga mpweya; osayenerera kukweza zitsulo zosungunuka, poizoni ndi zinthu zoyaka moto.
(3) Makina okweza
1. Mtundu wa trolley wawiricrane pamwamba: Njira zazikulu ndi zothandizira zokwezera zimapangidwa ndi (ma frequency osinthika) ma mota, mabuleki, ma gearbox ochepetsa, ma reels, ndi zina. Kusintha kwa malire kumayikidwa kumapeto kwa shaft ya ng'oma kuti achepetse kutalika ndi kuya kwake. Pamene malire atsegulidwa kumbali imodzi, kukwezako kumangoyenda mosiyana ndi malire. Pafupipafupi kutembenuka ulamuliro hoisting alinso okonzeka ndi deceleration malire lophimba pamaso mapeto, kotero kuti akhoza basi decelerate pamaso mapeto lophimba ndi adamulowetsa. Pali magiya atatu otsitsa makina okweza ma mota osasinthasintha. Giya woyamba ndi braking reverse, yomwe imagwiritsidwa ntchito potsika pang'onopang'ono katundu wokulirapo (pamwamba pa 70% yovotera). Giya yachiwiri ndi braking ya gawo limodzi, yomwe imagwiritsidwa ntchito potsitsa pang'onopang'ono. Amagwiritsidwa ntchito potsika pang'onopang'ono ndi katundu waung'ono (pansi pa 50% katundu wovotera), ndipo giya lachitatu ndi pamwamba ndi la kutsika kwa magetsi ndi kubwezeretsanso mabuleki.
2. Mtundu wokwera wamtengo umodzi: Njira yokwezera ndi cholumikizira chamagetsi, chomwe chimagawidwa m'magiya othamanga komanso ochepera. Amakhala ndi mota (yokhala ndi brake ya cone), bokosi lochepetsera, reel, chipangizo chokonzera chingwe, ndi zina zambiri. Sinthani nati mozungulira kuti muchepetse kuyenda kwa axial kwa mota. Kutembenuka kulikonse kwa 1/3, kuyenda kwa axial kumasinthidwa molingana ndi 0.5 mm. Ngati kuyenda kwa axial kuli kwakukulu kuposa 3 mm, kuyenera kusinthidwa nthawi.
(4) Njira yogwiritsira ntchito galimoto
1. Mtundu wa trolley wamtundu wawiri: The vertical involute gear reducer imayendetsedwa ndi galimoto yamagetsi, ndipo shaft yotsika kwambiri yochepetsera imagwirizanitsidwa ndi gudumu loyendetsa galimoto yomwe imayikidwa pamtundu wa trolley mumayendedwe apakati. Galimoto yamagetsi imagwiritsa ntchito shaft yotulutsa mbali ziwiri, ndipo mbali ina ya shaft imakhala ndi brake. Malire amaikidwa kumapeto kwa trolley frame. Pamene malire akuyenda mbali imodzi, kukwezako kumangoyenda mosiyana ndi malire.
2. Mtundu wokwezera mtengo umodzi: Trolley imalumikizidwa ndi njira yonyamulira kudzera m'chingwe chozungulira. M'lifupi pakati pa mawilo awiri a trolley akhoza kusinthidwa mwa kusintha bwalo la pedi. Ziyenera kutsimikiziridwa kuti pali kusiyana kwa 4-5 mm mbali iliyonse pakati pa gudumu la magudumu ndi mbali ya pansi ya I-mtengo. Zoyimitsa mphira zimayikidwa kumapeto kwa mtengowo, ndipo zoyimitsa mphira ziyenera kuyikidwa kumapeto kwa gudumu.
