Njira yophatikizira ya crane ya nsanja imapangidwa makamaka ndi kupha, kuyendetsa galimoto ndi chithandizo chapamwamba ndi chapansi.Kusonkhana kwa nsanja ya crane pogwira ntchito nthawi zambiri sikukhala kosalala ndipo phokoso limaposa cholakwika (phokoso lachilendo).Wolembayo adaphatikizana ndi zomwe adakumana nazo pantchito yochokera kukupha, makina ophera ndi kupha zolakwika motsatana, popanga, kuyezetsa msonkhano, kukonza zida ndi mbali zina za malingaliro awo ndi malingaliro awo.

Tower crane slawing ring ring njira zopewera ndi kukonza

1.kuwotchera mphete zida zofunika

Kulumikizana ndi kupindika kwa magiya pansi pa katundu womaliza ndi kutopa kunawerengedwa ndikutsimikiziridwa malinga ndi ISO6336-1: 2006, ISO6336-2: 2006 ndi ISO6336-3: 2006 motsatana.Sf ndi 1.48 ndipo chilolezo cha ma mesh cha giya chimasinthidwa kuti chikhale chokwera kwambiri cha ma radial othamangitsidwa ndi bwalo la giya lonyamula.Kuchotsa dzino locheperako nthawi zambiri kumakhala 0.03 mpaka 0.04x modulus, ndipo chilolezo cha ma mesh cha ma giya a pinion pagawo lonse chimayenera kuyang'aniridwanso pambuyo pomangirira komaliza kwa kupha.

2. Slewing kubala kondomu mkati
Pa ntchito tsiku ayenera nthawi yake, pa nthawi, malinga ndi malangizo Buku lililonse chigawo monga mafuta, mafuta, kondomu mkombero makonzedwe a kondomu.Zogwirizanamphete ya mpiraNthawi zambiri imadzazidwanso maola 100 aliwonse akugwira ntchito, mphete yodzigudubuza imadzazidwanso maola 50 aliwonse, chifukwa chafumbi, chinyezi chachikulu, kusiyana kwa kutentha kwapadera kwa malo ogwirira ntchito kuyenera kufupikitsa kuzungulira kwamafuta.Mafuta aliwonse ayenera kudzaza msewuwo mpaka mafutawo atuluke, ndikudzaza pang'onopang'ono pozungulira pozungulira kuti mafutawo adzaze.Podzaza kukonza kwamafuta opaka mafuta, kumatha kuchepetsa mikangano pakati pa magiya, kuchedwetsa kavalidwe ka mphete ya giya, mapangidwe a filimu yamafuta amathanso kuchita nawo gawo la mayamwidwe owopsa, kuchotsa gawo la mphamvu yakugwedezeka. pakugwira ntchito.Komanso lubricating mafuta filimu angakhalenso wabwino mafuta kuyeretsa mikangano pamwamba, kupewa dzimbiri, ndi kuthetsa chikoka cha chitsulo particles pa mikangano padziko.Kuti muchepetse phokoso losokoneza pakugwira ntchito ndikuwonjezera moyo wautumiki wa mbewa.

3.Kumangirira mabawuti
Maboti olumikizirana ndi kunyamula kwapamwamba ndi kumunsi kumayikidwa pa axial pulsating katundu kuwonjezera pa preload, zomwe zimapangitsa kuti ma bolt atambasulidwe kapena kuti olowa nawo asokonezeke, zomwe zimapangitsa kuti ma bolt asungunuke.Kutsegula kwapang'onopang'ono kwa bolt sikufika pakuwonjezeka kofunikira kwa axial chilolezo, kugudubuzika kwa ma torque akuluakulu, m'mphepete mwa msewu chifukwa cha kupsinjika kwakukulu, zomwe zimapangitsa kuwonongeka kwa msewu.Mzindawu unali ndi chiwongolero chapamwamba cha QTZ 25 tower crane chogwetsa ngozi, chomwe chimayambitsa ngozi ndi kupha ndi mabawuti apamwamba m'mikhalidwe yosadziwika yantchito, zomwe zidapangitsa kuti gulu lililonse la bawuti motsatizana litsatire zambiri kuposa kunyamula kwake. mphamvu ya gulu la bawuti.Izi zinapangitsa kuti mawonekedwe apamwamba a nsanjayo (ndi kupha kwake) awonongeke kuchoka ku nsanjayo ndikugwetsa.Chifukwa chake, kukhazikika kwa bawuti yoboola komanso kusankha kwake kwamphamvu ndikofunikira kwambiri.

4. Kuyika ndi Ntchito

Kuyika mphete yowotchera kuyenera kusankhidwa ndi mabawuti amphamvu kwambiri, mabawuti ndi mtedza ziyenera kutsatira zofunikira za GB3098.1 ndi GB3098.2 zomwe zimaletsa kugwiritsa ntchito makina ochapira masika.Musanayambe kulimbitsa ma bolts okwera, kusintha kwa ma singge gear meshing (chilolezo cham'mbali) kuyenera kuchitidwa kuti kuwonetsetsa kuti ma slewing bearing ndi ma pinion mesh akwaniritse zofunikira.Limbikitsani ma bolts okwera ayenera kukhala pa 180 °, ndege yoyikapo iyenera kukhala yoyera komanso yosalala, yopanda ma burrs, shavings yachitsulo ndi zinyalala zina, ndegeyo iyenera kukwaniritsa zofunikira.

Tower crane slewing mphete nthawi zambiri imakhala ndi mano osweka, kotero crane ya nsanja yomwe ikugwira ntchito iyeneranso kuganizira momwe mphepo imakhudzira mphete yophera, ngati kuposa momwe mphepo yapangidwira kapena kuyimitsa ntchito pambuyo poti crane boom siyingazungulire. momasuka ndi mphepo, izi zikhoza kuwononga giya ndi kupha chinkhoswe kapena kupha mphete, ngozi yaikulu idzachitika.Chifukwa chake crane ya nsanja pakuyika ndikugwiritsa ntchito iyenera kuwunika mwatsatanetsatane.
