Kwiindawo ezisebenzisa isinyithi, izixhobo zokuphakamisa kufuneka zihlangabezane nemigangatho ephezulu kakhulu yokhuseleko, ukuqina, kunye nokumelana nobushushu. Le projekthi ibonisa ukubonelelwa ngempumelelo kweI-crane ephezu kwentloko yesitayile saseYurophu esine-girder ephindwe kabiniyenzelwe ngokukodwa umsebenzisi we-metallurgical eCôte d'Ivoire, apho i-crane isetyenziselwa ukuthuthailothe enyibilikisiweyoukuya kumzi-mveliso wokucoca phantsi kweemeko zokusebenza ezinzima.
Isishwankathelo seProjekthi
I-crane yaziswa phantsiI-CIF Abidjanimiqathango enomjikelo wemveliso kunye nokuhanjiswaIintsuku ezingama-40 zokusebenza, ithunyelwe ngenqanawa. Intlawulo ilungiselelwe ngeT/T 70%, ebonisa ukuthembana okuqinileyo phakathi kwamaqela omabini. Njengomsebenzisi wokugqibela kwiimboni yesinyithi, umthengi ugxininise kakhulu kumgangatho, imigangatho yokhuseleko, kunye nokuthobela ngokungqongqo imizobo yakhe yobugcisa.
Isisombululo sokugqibela yayikukubaI-crane yaseYurophu enee-girder ezimbini ngaphezulu, imodeliQDY, kunyeUmthamo olinganisiweyo we-7/3-ton, ixesha elideIimitha ezili-18.22kunye nokuphakama okuphezuluIimitha eziyi-7.75I-crane isebenza ngeulawulo olukude lwerediyo kunye nolawulo olujikelezayo, Ixhaswa nguUmbane we-400V, 50Hz, onamabakala amathathu, ukuqinisekisa ukuphathwa okuzinzileyo nokuchanekileyo kwindawo enobushushu obuphezulu.
Uqwalaselo lobuchwephesha kunye neemfuno ezikhethekileyo
Ngokungafaniyo neekhreyini eziqhelekileyo zoshishino, esi sicelo besifunai-crane ephezu kwentloko ye-metallurgical double girderNgexesha lonxibelelwano lokuqala, umthengi ubonise imizobo yakhe kodwa akazange ayichaze ngokucacileyo indlela esetyenziswa ngayo isinyithi. I-crane eqhelekileyo ye-double girder yacatshulwe ekuqaleni. Nje ukuba umthengi acacise ukuba i-crane iza kuphathailothe elulwelo kumaqondo obushushu aphezulu, iimfuno zeprojekthi zitshintshe kakhulu.
I-crane iphuculwe ukuze ihlangabezane ne-iklasi yokusebenza A7(kunye neemeko zokusebenza zokwenyani kwi-A5), kubandakanyaumaleko wokugquma ubushushuukukhusela izinto zokwakha nezombane kubushushu obukhanyayo. Ukuphakama kofakelo bekulungelelaniswe kwiIimitha eziyi-9.41, kunye nokuphakama kwekholamu kwiIimitha ezi-7.8, efuna ulawulo oluchanekileyo lobukhulu. Ulwakhiwo oluphambili lwentsimbi lwenziwe ngeIntsimbi enamandla aphezulu ye-Q345, ukuqinisekisa amandla okuthwala umthwalo agqwesileyo kunye nokumelana nokudinwa.
Ukuphucula ukuthembeka kokusebenza,Ii-inverters ze-frequency zeSchneiderzikhethwe ukuze zilawule isantya ngokutyibilikayo, ngelixa ikhabhinethi yombane yayixhotyiswe ngeinkqubo yokupholisa umoya ngokunyanzeliswaukugcina amaqondo obushushu ezinzile kwiimeko ezinzima. Ingqwalasela ekhethekileyo inikwe nakwimida yobukhulu:Ubude benqwelo yokugqibela yendlela yokuhamba ngekreyini bebulinganiselwe ngokungqongqo kwi-4472 mm, kwaye ukulinganiswa kwamandla emoto kuhambelaniswe ngokuchanekileyo nemizobo yesalathiso yomthengi.
Inkqubo igqityiwe ngeIireli ezingama-60×40 (18 m × 2)kunyeIbha yomqhubi engenamthungo ye-250A (18 m), ukuqinisekisa umbane ozinzileyo kunye nobomi benkonzo ende.
Inkqubo yoNxibelelwano lwaBathengi kunye neSigqibo
Umthengi wayenamava angaphambili ngeIikhreyini zesinyithi zophawu lwaseJamani, eyayinika ukusebenza okuthembekileyo kodwa ngexabiso eliphezulu kakhulu. Ngokuchaza ngokucacileyoumahluko wesakhiwo, ubushushu, kunye noweklasi yomsebenzi phakathi kweekhreyini eziqhelekileyo kunyeiikhreyini ezixhonywe phezulu zesinyithi, sibonakalise ubuchule bethu kwezobugcisa kunye nokukwazi kwethu ukuhlangabezana nemigangatho yamazwe ngamazwe ngelixa sigcina ixabiso elikhuphisanayo.
Ngokuphendula ngokukhawuleza, ukucaciswa kobuchwephesha, kunye nokwenza ngokwezifiso ngokuchanekileyo ngokusekelwe kwimizobo yomthengi, kwasekwa ukuzithemba. Ekugqibeleni, umthengi wagqiba ekubeni afake iodolo kuthi, eqonda ibhalansi phakathiumgangatho wobunjineli, amandla okwenza ngokwezifiso, kunye nokusebenza kakuhle kweendleko.
Isiphelo
Le projekthi igxininisa indlela eyilwe ngayo ngokufanelekileyoi-crane ephindwe kabini ephezu kwendluinokuxhasa ngokukhuselekileyo nangokufanelekileyo imisebenzi yesinyithi ebandakanya amaqondo obushushu aphezulu kunye nemithwalo enzima. Ngemigangatho yoyilo yaseYurophu, izinto zombane eziphambili, kunye nokubambelela ngokungqongqo kwiinkcukacha zabathengi, i-crane ibonelela ngesisombululo esithembekileyo sexesha elide kwiindawo zoshishino ezifuna amandla—okubonisa ukuba ii-crane ezenziwe ngokwezifiso ezenziwe eTshayina zinokukhuphisana ngempumelelo neempawu zaseYurophu ezisemgangathweni kwizicelo eziphezulu.
