Kuwunika mawonekedwe a crane (yopachika) masikelo (II)

Zaka zingapo zapitazo ndinamva kuti katswiri akufuna kukonzekera muyezo wa mankhwala pa "mamba a crane wamphamvu", koma pazifukwa zina sizinayambitsidwe.M'malo mwake, malinga ndi kugwiritsa ntchito sikelo ya crane idzangoyikidwa ngati sikelo yokhazikika, pali zovuta zambiri zomwe sizingafotokozedwe bwino.

A zamphamvucrane scaleiyenera kukhala sikelo ya crane yomwe imalemera pamene katundu akukweza ndikusuntha nthawi imodzi panthawi yokweza.Ndikovuta kusiyanitsa pakati pa sikelo yosunthika ndi sikelo yokhazikika ngati ingofotokozedwa motere.Chifukwa "kulemera kwamphamvu" kumatanthauza: katundu woyezedwa ndi chonyamulira sikelo pali kusuntha kwapang'onopang'ono, pomwe sikelo yoyezera pakati pa awiriwo palibe kusuntha kwachibale, pokhapokha muzochitika zambiri zogwiritsira ntchito sikelo, chifukwa cha zida zopachikika za zida zawo. anu original.Popeza kuti chinthu choyenera kuyezedwa sichitha kupuma kwakanthawi kochepa, ngakhale mtengo utawerengedwa, umakhala wosiyana pang'ono ndi mtengo wopuma.

Masikelo a crane amaphatikiza masikelo a mbedza, masikelo amtundu wa crane, masikelo a gantry (mlatho).Ndipo masikelo amtundu wa crane amalemera pafupifupi mtundu wa trolley, mtundu woyezera chingwe cha waya, mtundu wolemera wa pulley ndi zina zotero.Hook mutu crane scale ndi katundu selo anaika mwachindunji pa mbedza mutu wa zida zonyamulira, izi structural mawonekedwe a crane sikelo, ambiri a kuphatikiza zosiyanasiyana katundu maselo.Sikelo za Gantry (mlatho) wa crane, ambiri omwe ndi amtundu wa waya wolemera.

Tikayang'ana pa sikelo monga sikelo ya crane yokha, imatha kufotokozedwa ngati "sikelo yodziyimira yokha".Komabe, ngati tiyang'ana pa dongosolo lonse lokwezera, kaya ndi crane ya mlatho wa m'mphepete mwa nyanja kapena gantry system mu doko, kapena makina okwera pamwamba pa bizinesi ya mafakitale kapena migodi, zonsezi sizingasiyanitsidwe ndi chingwe chachitali cha chingwe, ndipo onse akuyang'ana zinthu zoyezedwa panthawi yokweza ndi kusuntha mtengo wamtengo wapatali.Ndi chifukwa cha njira yoyezera komanso chingwe cha waya zomwe zimapangitsa kuti pakhale mavuto awiri ogwiritsira ntchito masikelo a crane:

(1) Pakukweza, pansi pa mphamvu yonyamula zida ndi mphamvu yokoka ya katundu, chingwe cha waya chomwe chimayimitsa sikelo ya crane mosakayikira chimatambasulira ndikudutsa, ndipo nthawi zina zida zonyamulira zomwe zimayimitsa sikelo ya crane ndizosapeweka. kunjenjemera.Ndili mu zotanuka izi, sikelo ya crane siyingafikire zotsatira za mtengo woyezera munthawi yake.

(2) Nthawi zambiri, sikelo ya crane imagwiritsidwa ntchito panja, idzakhudzidwa ndi chilengedwe, makamaka miyeso ya crane yomwe imagwiritsidwa ntchito padoko, ndi mphepo idzatulutsa oscillation ya sikelo ya crane idzakhala yochulukirapo kulimbikitsa kunjenjemera kwa waya. chingwe, komanso zimakhudza zotsatira za osati mu nthawi kupeza masekeli zotsatira za zinthu.
