I-Universal Lifting and Travelling Double Girder Gantry Crane Iyathengiswa

I-double girder gantry crane iyisisombululo sokuphakamisa esindayo esiklanyelwe ukuphatha imithwalo emikhulu neyinqwaba ezindaweni ezifunwa kakhulu zezimboni. Ngesakhiwo sayo esiqinile se-double-girder kanye ne-gantry, i-crane inikeza amandla okuphakamisa ahlukile, isiteji sokusebenza esizinzile, nokusebenza okuthembekile kwesikhathi eside. Ifakwe ama-trolleys anembayo namasistimu kagesi athuthukile, aqinisekisa ukuphathwa kahle kwezinto ezibonakalayo, okushelelayo, nokunemba kuzo zonke izinhlelo zokusebenza ezihlukahlukene.

Ifaka i-span enkulu, ukuphakama okulungisekayo kokuphakamisa, isakhiwo esihlangene, nokusebenza okuvumelana nezimo, i-double girder gantry crane ifinyelela umthamo oqinile wokuthwala umthwalo kanye nokusetshenziswa kwesayithi okuphezulu. Lokhu kuyenza ilungele ukusebenza okunhlobonhlobo, okuhlanganisa amachweba, izindawo zemikhumbi, izimboni, izindawo zokugcina impahla, namagceke amakhulu okugcina angaphandle. Ngezinhlelo zokusebenza zangaphandle, i-crane ingabuye ifakwe izinto zokuphepha nezokuvikela ezifana nezinsimbi zesitimela, amadivaysi okunamathisela, amasistimu okubamba izintambo, kanye nesivinini somoya noma amamitha okuqondisa umoya ukuze kuqinisekiswe ukusebenza okuphephile nokuzinzile ngaphansi kwezimo zezulu ezihlukene.

Uma kuqhathaniswa nama-cranes e-single girder, i-double girder gantry crane inikeza amandla aphezulu okuphakamisa, ukucushwa okuyinkimbinkimbi, kanye nokuvumelana nezimo ezinkulu emsebenzini osindayo kanye nokusebenza okuqhubekayo. Ifaneleka ngokukhethekile ukuphakamisa imithwalo esinda kakhulu, ukusebenza ngaphansi kwezimo ezinzima, noma ukuhlangabezana nezinye izidingo zokusebenza ezikhethekile. Ngamandla amakhulu okuphakamisa afinyelela kumathani angama-320 kumaphrojekthi ethu, imingcele yedizayini efana nobude, ubude bokuphakamisa, nomsebenzi wokusebenza ungalungiselelwa ukuhlangabezana nezidingo zezimboni ezihlukahlukene.

Enkampanini yethu, sibeka phambili ikhwalithi nokuphepha kunamasu entengo aphansi. Wonke ama-double girder gantry crane akhiqizwa ngamazinga aqinile ukuze kuqinisekiswe ukwethembeka, ukuqina, nokuphepha komsebenzisi. Ngalawa mandla, i-double girder gantry crane isibe ucezu lwemishini ebalulekile ekukhiqizeni kwezimboni zesimanje kanye nokuphathwa kwempahla.

Amagida: Amagida ayinhloko yibhokisi elisindayo noma imishayo ye-truss eyenziwe ngensimbi yesakhiwo esinamandla aphezulu (isibonelo, i-Q345B noma okulinganayo). Idizayini yegida eliphindwe kabili ijwayelekile kumthamo we-40 t, ihlinzeka ngokuqina namandla. Izinsimbi zamabhokisi zinikeza ifomu elihlangene, eliqinile; ama-truss girders (asetshenziswa kumamodeli wethu we-Truss Gantry) anciphisa isisindo isikhathi eside kakhulu. Amagida ashiselwe ngokunembile futhi anciphisa ukucindezeleka ukuze kuncishiswe ukuguga. I-span (ibanga eliphakathi kwemilenze noma amasondo) kanye nobude begirder bunjiniyela ngokwesigaba somthwalo kanye nomsebenzi. Amaloli okugcina axhumeka kumagida futhi afake amasondo okuhamba nge-crane.

I-Trolley ne-Hoist: I-trolley (noma inkalankala) ihamba ngojantshi phezu kwamabhande futhi iphethe indlela yokuphakamisa. Ngomthamo ongu-40 t, ngokuvamile sisebenzisa i-hoist yentambo ene-gearbox eqinile kanye nenjini. I-hoist ihlanganisa intambo yensimbi eboshelwe esigubhu, ibhuleki le-multi-plate friction, kanye nebhulokhi enehuku elisindayo. Kweminye imiklamo i-twin-hoist trolley (ama-hoist amabili kubhande elilodwa) iyatholakala ukuze isakazwe isikhathi eside. Isivinini sokuphakamisa kanye netorque kuhlangabezana nesilinganiso somsebenzi we-crane (isibonelo, izilinganiso ze-FEM/ISO). Umkhawulo wokushintsha ohambweni olungaphezulu/oluphansi luvikela ekuphakameni ngokweqile noma ngaphansi. Wonke ama-hoists aklanyelwe amazinga e-ISO kanye ne-CMAA, futhi intambo yocingo ihlangabezana ne-ISO 4309 (ukuhlola nokunakekelwa). Uhlaka lwe-trolley luyinsimbi eshiselwe, futhi amasondo ayinsimbi enephrofayili enama-bearings avaliwe.

Imilenze Nezisekelo: Kuma-cranes akhwele isitimela, amafreyimu emilenze angamakholomu esigaba sebhokisi aqinile, aqondaniswe ngokunembile nemishayo yendlela yezindiza. Idizayini yomlenze ovumelana nezimo iyatholakala ukuze ilungiselwe ukungahambi kahle komzila wezindiza omncane. Umlenze ngamunye uphethe ama-drive motors (amaloli okugcina) namasondo aginqika kumareyili. Imilenze iboshelwe kumagida ukuze izinze. Kumacranes e-RTG, “imilenze” amakholomu ozimele wephothali amakhulu anamathayi amakhulu omoya. Amasilinda e-RTG emilenze ye-hydraulic aqondisa amasondo futhi asekele ibhuloho. Zonke izakhiwo zemilenze zipendwe ngezingubo zasezimbonini ukuze kuvikelwe isimo sezulu (isb. upende lwangaphandle oluvimbela ukugqwala).

Amadrayivu kanye Nezimotho: Iloli ngalinye elisekupheleni linikwa amandla yinjini ye-AC ehlanganiswe nebhokisi legiya ukuze kuhambe kahle ibhuloho le-crane. Uhambo lwetroli luphinde lusebenzise injini kanye nebhokisi likagiya (elihlukene namadrayivu ebhuloho). Izinjini zinamandla adingekayo (ngokuvamile afinyelela emashumini ama-kW) futhi afaniswa nomjikelezo womsebenzi. Kokhreni abathaywe ngenjoloba, izinjini zikadizili ezinamadrayivu asebenza ngogesi zingaqhubeza ukhreyini (okujwayelekile kuma-RTG amaningi), noma sihlinzeka ngama-RTG kagesi wonke (ngejeneretha yangaphakathi noma ibhethri). Wonke ama-motor ane-insulation yezimboni kanye nezilinganiso ze-IP (imvamisa i-IP54 noma okungcono). I-Variable Frequency Drives (VFDs) ivamise ukusetshenziselwa ukulawula isivinini esihle nokonga amandla ohambweni lwebhuloho nenqola.

Isistimu kagesi: Isistimu yokulawula ugesi ye-crane ibekwe endaweni eyodwa kuphaneli ebekwe phansi noma ebekwe odongeni, eyakhelwe kumazinga e-IEC. Izilawuli zifaka phakathi ukuqala/ukuma nesikhombisi-ndlela se-hoist, trolley, kanye nokunyakaza kwebhuloho. Izinketho zokuphakela amandla zihlanganisa ibha yokuqhuba (ibha yebhasi), i-cable reel (isistimu ye-festoon), noma ukuxhumana kwangaphandle (kokhreyini be-RTG). Izindlela zokulawula kungaba isiteshi esilengayo senkinobho yokucindezela, ikhonsoli ye-cabin operator, noma isilawuli kude esingenantambo. Amasekhethi okuphepha asebenzisa othintana nabo bezimboni nama-relay, futhi isilawuli se-PLC esingakhethwa siyatholakala ukuze sizenzekele (isibonelo, isilawuli sokushayisana esihlelekayo phakathi kwama-cranes). Amasekhethi ezitobhi eziphuthumayo awasasebenzi. Uhlelo luhlanganisa amathuluzi okuvikela kagesi (ama-fuse, ama-relay alayishiwe ngaphezulu) kanye nezimfuneko ze-OSHA/ANSI ngayinye.

Amadivayisi Okuphepha: I-40 Ton Gantry Cranes yethu ihlanganisa amadivayisi amaningi okuphepha. Lokhu ngokuvamile kufaka ukuvikela ukugcwala ngokweqile (amaseli okulayisha noma amathuluzi akhawulela) ukuvimbela ukuphakamisa ngaphezu komthamo olinganiselwe; ukushintshwa komkhawulo ophezulu/ophansi ukuze kumiswe ukuhamba kwe-hoist ezindaweni zokugcina; ukushintshwa komkhawulo wokuhamba kwebhuloho ukuvimbela ukugcwala komzila wezindiza; izinkinobho zokumisa izimo eziphuthumayo ezifinyeleleka ku-opharetha; nonogada abazungeza izingxenye ezihambayo. Imishini yokunqanda ukushayisana (izinzwa zerada noma i-laser) ingafakwa kumakhreni esiqukathi ukuze kugwenywe ukuthintana phakathi kwamakhreni aseduze. Izici ongazikhethela zifaka phakathi ukulawulwa kwe-anti-sway (ukuswayipha kokulayisha) kanye nezinhlelo zokubona kwekhamera. Wonke amadivayisi okuphepha ayahlolwa ngesikhathi sokusebenza, futhi ukujikeleza kuhlangabezana nezidingo zekhodi yokuphepha ye-OSHA ne-ASME.
