Kodi Steel Structure Crane Beam ndi chiyani?
Crane steel girders ndi gawo lofunikira la ntchito iliyonse yomanga yomwe imafuna kugwiritsa ntchito ma cranes.Mtengo uwu wapangidwa mwapadera kuti upereke chithandizo ndi kukhazikika kwa crane ponyamula ndi kusuntha katundu wolemetsa.Mphamvu zake ndi kulimba kwake kumapangitsa kuti ikhale yabwino kwambiri pantchito yomanga.
Mawu akuti "steel structure crane beam" amatanthauza membala wopingasa yemwe amadutsa mbali ziwiri kapena kupitilira apo.Imakhala ngati chimango kuti crane igwire ntchito ndipo imapereka nsanja yokhazikika yonyamulira ndi kusuntha zinthu.Mitengoyi imapangidwa kawirikawiri kuchokera kuzitsulo chifukwa cha mphamvu zake zolemera kwambiri, zomwe zimathandiza kuti pakhale makina akuluakulu komanso ogwira mtima.
Mawonekedwe a mtengo wachitsulo wa crane:
1.Box girder design
Imodzi mwa mitundu yodziwika bwino ya zitsulo zomangira crane girders ndi kapangidwe ka bokosi.Mapangidwe ake amakhala ndi mawonekedwe a rectangular omwe amapereka mphamvu zabwino kwambiri komanso kunyamula katundu.Ma flanges apamwamba ndi apansi a bokosi girder amalumikizidwa ndi ukonde woyima kuti apange mawonekedwe olimba komanso okhazikika.Mapangidwe a Box girder nthawi zambiri amayamikiridwa chifukwa chakuchita bwino kwawo polimbana ndi mphamvu zopindika, zomwe zimawapangitsa kukhala oyenera kunyamula katundu wolemetsa.
2.I-mtengo mapangidwe
Mtundu wina wotchuka wa chitsulo cha crane girder ndi kapangidwe ka I-beam.Mitengo ya I, yomwe imadziwikanso kuti matabwa apadziko lonse kapena H-mitengo, imafanana ndi chilembo "I" pamtanda.Ma flanges apamwamba ndi apansi a I-beam amalumikizidwa ndi ukonde woyima kuti apange mawonekedwe amphamvu komanso okhazikika.Mapangidwe a I-beam amadziwika kuti ali ndi mphamvu zowonjezera mphamvu, zomwe zimapangitsa kuti zikhale zoyenera kwa mapulogalamu omwe kuchepetsa kulemera kumakhala kofunikira.Amagwiritsidwa ntchito nthawi zambiri m'malo okhala ndi malo ochepa kapena zoletsa zautali chifukwa amalola kuchuluka kwa katundu pamapangidwe ang'onoang'ono.
3. Zomangamanga za Truss
Kuphatikiza pa mapangidwe a girder ndi I-beam, ma girders achitsulo amabwera m'njira zina monga ma truss girders ndi truss girders.Miyendo ya truss imakhala ndi magawo angapo olumikizana atatu, omwe amapereka kusinthasintha komanso kuchita bwino pakugawa katundu.Komano, matabwa a lattice amapangidwa ndi maukonde otseguka omwe ali ndi mamembala a diagonal, zomwe zimapangitsa kuti pakhale kulemera kwake komanso mtengo wake.
Kapangidwe kameneka kakamalizidwa, kupanga ndi kukhazikitsa chitsulo chachitsulo cha crane chingayambe.Njira yopangira zinthu imaphatikizapo kudula ndi kupanga zigawo zazitsulo molingana ndi ndondomeko ya mapangidwe.Njira zowotcherera nthawi zambiri zimagwiritsidwa ntchito pophatikiza magawo osiyanasiyana, kuwonetsetsa kuti mtengowo umagwirizana.
Pakuyika, mtengo wachitsulo wa crane umalumikizidwa bwino ndi malo othandizira, nthawi zambiri amagwiritsa ntchito mabawuti kapena kuwotcherera.Kuyanjanitsa koyenera ndi kusanja ndikofunikira kuti mtengowo ugwire ntchito moyenera komanso umathandizira kuyenda kwa crane.Kuonjezera apo, kumangirira kokwanira ndi kulimbikitsanso kungafunike kuti muthe kukhazikika komanso kunyamula katundu wa mtengowo.
Kusunga chitsulo cha crane mtengo ndikosavuta poyerekeza ndi mitundu ina ya zida zomangira.Kuyang'ana pafupipafupi kumalimbikitsidwa kuti muwone ngati pali zisonyezo zakutha, kuwonongeka, kapena kusinthika kwamapangidwe.Ngati pali zovuta zomwe zapezeka, ziyenera kuthetsedwa mwachangu kuti zipewe kuwonongeka ndikuwonetsetsa kuti crane ikuyenda bwino.
