GBT 15-88 umutwe munini uzengurutse hamwe na mortise bolt
Imiyoboro ya Countersunk ikoreshwa muguhuza ibintu bibiri cyangwa byinshi kandi ni ngombwa mubuzima bwa buri munsi cyangwa mu nganda.
Icyuma kigizwe n'umutwe hamwe na screw (silinderi ifite imigozi yo hanze), ikoreshwa hamwe nutubuto two gufunga ibice bibiri hamwe nu mwobo.
Ubu bwoko bwihuza bwitwa bolt ihuza. Niba ibinyomoro bidakuwe muri bolt, ibice byombi birashobora gutandukana, bityo ihuza rya dowel ni ihuriro ritandukanijwe.
Umunara wa crane bolt irekuye uburyo bwo gukemura ikibazo cya bolt irekuye
Niyihe mpamvu yo kurekura umunara crane bolt? Nigute wakemura ikibazo cyo kurekura umunara wa crane? Ikintu kimwe gishoboka nuko bitewe nubukanishi, bolt ntabwo irekuye bihagije kugirango itere kurekura; Hariho kandi amahirwe yo kwirengagiza abantu no kunanirwa gukomera. Kandi bolt anti loose akenshi ntabwo ari nziza hamwe na bolt yakozwe neza ntabwo iri hejuru, inenge yubushakashatsi bwatewe; Ahari bolt yashizwemo kandi irasenywa inshuro nyinshi, kandi iryinyo ryinyo iranyerera.
Bikunze gukoreshwa tm 60, 80 tm umunara wa crane yometse munsi yavuzwe haruguru ni icyuma cyogosha, jib, ukuboko kuringaniza, imipira yumunara, cab, nibindi, uburemere bwacyo kuri 20 ~ 30 t, muburyo bukora umunara wa crane, na vertical imbaraga zakozwe na dinamike yumutwaro nigihe cyo kugunama, torque, bityo rero ibyingenzi bisabwa guhuza bigomba kuba bihuye neza nibiteganijwe, umwanya wo gukomera, ntabwo ufunze cyane cyangwa urekuye cyane, cyane, Bolt izakora igihe kirekire igihe cyangwa hafi yo gutanga imbaraga, kugirango bolt ihite umunaniro kandi ucike, bikavamo kuvunika; Kurekura cyane, guhinduranya no guhuza ibice bigenda, umutwe wa bolt munsi yumutwaro wangiritse no kwangirika, bikaviramo impanuka zikomeye za umunara.
Mubikorwa bya umunara crane, akenshi bikorerwa kunyeganyega, ingaruka hamwe numutwaro uhinduka, kandi hariho ibihe nibihe bihindagurika cyane. Muri ubu buryo, imbaraga zo guterana hagati yimigozi ihindagurika hejuru ya bolt ihuza irashobora gucika cyangwa kugabanuka ako kanya. Gusubiramo inshuro nyinshi ibi bintu bizatuma ihuriro rihinduka buhoro buhoro, bigira ingaruka ku gukomera no gukomera kwihuza Ibi birashobora kubaho mugice icyo aricyo cyose gisanzwe cyumubiri wumunara, kandi irekura rya bolt mubice byavuzwe haruguru bifatwa nkikintu cyumuntu. Kwizamura umunara wa crane kuzamura umunara, mbere ya buri munara crane jack-up, byose bihuza ibisate kugirango urekure bine cyangwa umunani, impera yimbere, kumenyekanisha iminara nibisanzwe, igice gisanzwe kizamenyekanisha igice gisanzwe, munsi yo kuzenguruka hejuru no hepfo imiyoboro hagati ya bolting, nigice cyo hepfo cyo guhuza bolt ntisanzwe yirengagiza, ikomeza ako kanya, kandi munsi yizunguruka yikintu cyo hejuru hagati ya bolt Mubikorwa byo gukomera, akenshi ntabwo ihita ikomera kuko habaho jacking zirenze imwe igice wongeyeho igice gisanzwe na jacking birakomeza. Muri ubu buryo, birashoboka ko guhuza ibice byuru rwego bitagabanijwe nyuma yuko jacking irangiye. Urugero ruboneka mu igenzura ni urugero.
Bolt ihuza ibisabwa kugirango umunara wa crane usanzwe:
*. gucika umunaniro, wasangaga no mubizamini nyirizina umunani shingiro ya bolt yamenetse, ni iyiki kintu. Hagomba kwitonderwa guhora kwa torque mbere yo gukomera mugushiraho. Mubikorwa byumurima, bitewe nimbaraga zinyuranye zabakozi, mbere yo gukomera kwumuriro wa bine yinkingi zishobora kuba zitandukanye, bityo ikoreshwa ryumurongo wa torque rirashobora kugenzurwa neza. Kuvuga make, bigomba no kugenzurwa no guhindurwa na ba shebuja bafite uburambe.
Icya kabiri, imiterere yo gufunga ibice byose bihuza bigomba kugenzurwa rimwe nyuma yo gutangira kwambere umunara wa crane imaze gukora inshuro ebyiri. Mu gice cyakurikiyeho ukwezi cyangwa ukwezi, ibihindu mubice byavuzwe haruguru bigomba kugenzurwa cyane cyane nyuma yumunara. Umwanya wamaboko yumunara ugomba no kuzunguruka mugihe ugenzura. Bolt igomba kugenzurwa iri munsi yumwanya wikiganza kiringaniye, kuburyo yizewe kandi ikora neza niba igenzurwa.
Icya gatatu, iyo umunara wa crane wimuwe, umubiri wose wumunara uhuza ibimera ugomba kugenzurwa muburyo burambuye, ugasiga no gusiga. Kuvunika, kwambara, ingese zikomeye, muri rusange cyangwa guhindagurika kwa plastike hamwe nibindi bidasanzwe bigomba gusimburwa. Birasabwa kuyikoresha inshuro zirenze ebyiri kugirango wirinde kwangirika. Iki gisabwa, umunara uriho crane ntishobora kuba yujuje ubwinshi. Niba bigaragaye ko hari ikibazo, ntigomba gutunganywa no gukorwa wenyine. Kuberako igice cyubwubatsi kitoroshye kugenzura ubuziranenge bwibikoresho nibikoresho bya bolt nziza, byakagombye kuba byiza ubiguze kuva muruganda rwambere rukora inganda. Bolt nziza igomba kurangwa nuwabikoze nu ntera.
Sisitemu yo kugenzura umutekano wumunara hamwe na anti-kugongana ikoreshwa muburyo bwimikorere yimikorere ya crane yimikorere yumutekano wo kurwanya impanuka mugihe cyubwubatsi bugoye, irashobora gukumira neza impanuka ya crane umunara, gukumira no kugabanya kugongana mubikorwa bikorana nitsinda ryimashini, kunoza umutekano wubwubatsi bwikibanza! Sisitemu iroroshye gushiraho no gukora, kandi irashobora gutabaza no kurinda umunara wa crane nyinshi mukarere runaka k'urubuga. Muri icyo gihe, sisitemu yo kurwanya kugongana umunara ni sisitemu yo kugenzura umutekano kandi ikora neza, ishobora gufasha abakora crane umunara kwirinda impanuka zikomeye ndetse n’impfu zatewe namakosa yo gukora.
