I-slewing mechanism ye-tower crane yakhiwe ikakhulukazi i-slewing bear, i-slewing drive kanye nokwesekwa okuphezulu nangaphansi.Umhlangano we-tower crane slewing in the process ngokuvamile ngeke usebenze kahle futhi umsindo ungaphezu kwephutha elijwayelekile (umsindo ongavamile).Umbhali uhlanganise nesipiliyoni sakhe sokusebenza esivela ku-i-slewing bear, indlela yokubulala kanye namaphutha okubulala ngokulandelana ngokulandelana, ohlelweni lokukhiqiza, ukuhlolwa komhlangano, ukugcinwa kwemishini kanye nezinye izici zemibono neziphakamiso zabo.

Izinyathelo zokuvimbela nokugcinwa kwe-tower crane slawing ringi yokwehluleka

1.izidingo zegiya leringi

Amandla okuxhumana nawokugoba wamagiya ngaphansi komthwalo wokugcina nokukhathala abalwe futhi aqinisekiswa ngokuya nge-ISO6336-1:2006, ISO6336-2:2006 kanye ne-ISO6336-3:2006 ngokulandelanayo.I-Sf ingu-1.48 futhi imvume ye-gear mesh ilungiswa ukuze kube nephuzu eliphakeme kakhulu le-radial run out of the slewing bear bear gear pitch pitch circle.Ukususwa kwamazinyo okuncane kuvamise ukuba yi-0.03 kuya ku-0.04x modulus, futhi ukucaciswa kwenetha legiya lamagiya aphina kuwo wonke umzuliswano kudinga ukuphinde kubhekwe ngemva kokuqiniswa kokugcina kwe-slewing bear.

2. I-slewing ene-lubrication yangaphakathi
Ekusetshenzisweni kwansuku zonke kufanele kube ngesikhathi esifanele, ngesikhathi, ngokusho kwebhukwana lemiyalo yengxenye ngayinye ngokuya nge-lubricant, i-lubrication, amalungiselelo omjikelezo wokugcoba wokugcoba.Okuhambisanayoindandatho yokubulala ibholaimvamisa igcwaliswa kabusha njalo emahoreni ayi-100 okusebenza, iringi yokujula igcwaliswa njalo emahoreni angama-50, ngothuli olunothuli, umswakama ophezulu, umehluko wokushisa okuphezulu kwendawo yokusebenza okukhethekile kufanele unciphise umjikelezo wokugcoba.Ukugcotshwa ngakunye kufanele kugcwalise umgwaqo womjaho kuze kube yilapho isigcobo siphuma, sigcwale ngenkathi siphendukisa kancane i-slewing bear ukuze igrisi igcwale ngokulinganayo.Ngokugcwalisa ukugcinwa kwamafutha okugcoba, kunganciphisa ukungqubuzana phakathi kwebhangqa legiya, kunciphise izinga lokuguga lendandatho yegiya, ukwakheka kwefilimu kawoyela kungadlala indima yokumuncwa ukushaqeka, kususe ingxenye yamandla okudlidliza akhiqizwe. ekusebenzeni.Ngaphezu kwalokho, ifilimu yamafutha okugcoba ingase ibe yinto enhle yokugcoba ihlanze indawo yokungqubuzana, ivimbele ukugqwala, futhi iqede ithonya lezinhlayiya zensimbi endaweni yokungqubuzana.Ukuze kuncishiswe umsindo wokungqubuzana ekusebenzeni futhi kwandiswe impilo yesevisi ye-slewing bear.

3.Ukuqiniswa kwamabhawodi
Ama-bolts wokuxhuma we-slewing bear kanye ne-slewing bearings ephezulu naphansi angaphansi komthwalo we-axial pulsating ngaphezu kokulayishwa kwangaphambili, okuzokwenza ukuthi ama-bolts anwetshwe noma indawo ehlangene ikhubazeke, okubangela ukuba ama-bolts akhululeke.Ukulayishwa kwangaphambili kokuxegiswa kwe-bolt akufinyeleli ekwenyukeni kwe-axial clearance edingekayo, umzimba oginqikayo ngokuphenduka okukhulu kwetorque egingqikayo, unqenqema lomjaho ngokucindezeleka okukhulu kokuxhumana, okuholela ekulimaleni konqenqema lomjaho.Idolobhakazi libe nesakhiwo esingaphezulu se-QTZ 25 tower crane egumbuqela ingozi, imbangela eqondile ukugwazwa kanye namabhawodi okugwaza aphezulu ngaphansi kwezimo ezingashiwongo zomsebenzi, okuholele ekutheni iqembu ngalinye lebhawodi liphenduke, ngokulandelana okungaphezu kokuthwala kwalo. umthamo weqembu lomshudo.Lokhu kuholele ekutheni isakhiwo esingaphezulu sombhoshongo (ngokuthwala kwayo) sihlukane nesakhiwo sombhoshongo bese sidilika.Ukuqina kwebholidi ye-slewing bearing kanye nokukhethwa kwezinga lamandla kubaluleke kakhulu.Ngakho-ke, i-slewing bear bolt yokubopha kanye nokukhethwa kwezinga layo lamandla kubaluleke kakhulu.

4. Ukufakwa kanye nokusebenza

Ukufakwa kwendandatho yokuhlinza kufanele kukhethwe ngamabhawodi anamandla aphezulu, amabhawodi namantongomane kufanele kuhambisane ne-GB3098.1 kanye nezidingo ezijwayelekile ze-GB3098.2 ezivimbela ukusetshenziswa kwamawasha asentwasahlobo.Ngaphambi kokuqinisa amabhawodi afakayo, ukulungiswa kwegiya lokulinganisa (ukucaciswa kwezinhlangothi) kufanele kwenziwe ukuze kuqinisekiswe ukuthi i-slewing bear kanye ne-pinion mesh ukuhlangabezana nezidingo.Qinisa ama-bolts afakayo kufanele abe ku-180 °, indiza yokufaka kufanele ihlanzeke futhi isicaba, ingabi nama-burrs, ama-iron shavings nezinye izinsalela, indiza kufanele ihlangabezane nezidingo.

I-Tower crane slewing ring esebenza ngokuvamile izoba nokwehluleka kwamazinyo aphukile, ngakho-ke i-tower crane esebenzayo kufanele futhi icabangele umthelela womoya eringini yokubulala, uma ingaphezu komsebenzi oshiwo komoya noma ukumisa ukusebenza ngemuva kokuthi i-crane boom ingakwazi ukujikeleza. ngokukhululeka ngomoya, lokhu kungase kulimaze igiya kanye nokubandakanyeka kwe-slewing bear noma indandatho yokubulala, ingozi enkulu izokwenzeka.Ngakho-ke i-crane yombhoshongo ekufakweni nasekusebenzeni kufanele yenze ukuhlola okuningiliziwe.
