Iyini i-Steel Structure Crane Beam?
I-Crane steel girders iyingxenye ebalulekile yanoma iyiphi iphrojekthi yokwakha edinga ukusetshenziswa kwama-cranes.Le nsimbi iklanyelwe ngokukhethekile ukuhlinzeka ngokusekela nokuzinza ku-crane lapho uphakamisa futhi uhambisa imithwalo esindayo.Amandla ayo nokuqina kwawo kwenza kube ukukhetha okuphezulu embonini yezokwakha.
Igama elithi "i-steel structure crane beam" lisho ilungu lesakhiwo elivundlile elidlula ezindaweni ezimbili noma ngaphezulu zokusekela.Isebenza njengohlaka lwe-crane ukuze isebenze futhi inikeza inkundla ezinzile yokuphakamisa nokunyakaza kwezinto.Le mishayo ivame ukwenziwa ngensimbi ngenxa yesilinganiso sayo esiphakeme sokuqina kwesisindo, esivumela ukwakhiwa kwezinhlelo ezinkulu nezisebenzayo ze-crane.
Ifomu le-steel structure crane beam:
1.Box girder design
Enye yezinhlobo ezivame kakhulu zamagida ensimbi yesakhiwo se-crane yi-box girder design.Idizayini inomumo wonxande ongenalutho onikeza amandla amahle kakhulu namandla okuthwala umthwalo.Ama-flange aphezulu naphansi ebhande lebhokisi axhunywe ama-web aqondile ukuze akhe isakhiwo esiqinile nesiqinile.Imiklamo ye-box girder ivame ukuthandwa ngokusebenza kahle kwayo ekumelaneni namandla okugoba kanye ne-torsional, okuwenza afanelekele imisebenzi yokuphakamisa izinto ezinzima.
2.I-beam design
Olunye uhlobo oludumile lwe-steel crane girder ukwakheka kwe-I-beam.I-I-beams, eyaziwa nangokuthi imishayo yendawo yonke noma i-H-imishayo, ifana nohlamvu "I" esigabeni esiphambanayo.Ama-flange angaphezulu naphansi we-I-beam axhunywe ama-webs aqondile ukuze enze isakhiwo esiqinile nesiqinile.Umklamo we-I-beam waziwa ngezinga eliphezulu lamandla nesisindo, okwenza ulungele izinhlelo zokusebenza lapho ukunciphisa isisindo kubaluleke kakhulu.Ivamise ukusetshenziswa ezindaweni ezinemikhawulo elinganiselwe yesikhala noma ubude njengoba ivumela umthamo omkhulu wokulayisha ekwakhiweni okuhlangene.
3.Amagida e-Truss
Ngaphezu kwemiklamo ye-box girder kanye ne-I-beam, amagida ensimbi e-crane afika ngezinye izinhlobo njengama-truss girders nama-truss girders.Imishayo ye-truss iqukethe izigaba zikanxantathu ezixhumene eziningi, ezihlinzeka ngokuguquguquka nokusebenza kahle ekusabalaliseni umthwalo.Imishayo ye-lattice, ngakolunye uhlangothi, iklanywe ngamawebhu avulekile anamalungu adiagonal, okuvumela isisindo esilula kanye nesakhiwo esingabizi kakhulu.
Uma umklamo usuphothuliwe, ukwakhiwa nokufakwa kwe-steel structure crane beam kungaqala.Inqubo yokwenziwa ihilela ukusika nokubumba izingxenye zensimbi ngokusho kwemininingwane yokuklama.Izindlela zokushisela zivame ukusetshenziselwa ukuhlanganisa izingxenye ezihlukahlukene ndawonye, ukuqinisekisa ubuqotho besakhiwo se-beam.
Ngesikhathi sokufakwa, i-steel structure crane beam ixhunywe ngokuvikelekile ezindaweni zokusekela, ngokuvamile zisebenzisa amabhawudi noma i-welding.Ukuqondanisa kahle nokubeka ileveli kubalulekile ukuze kuqinisekiswe ukuthi ugongolo lusebenza kahle futhi lungasekela ukunyakaza kwe-crane.Ukwengeza, ukubopha okwanele nokuqinisa kungase kudingeke ukuze kuthuthukiswe ukuzinza okuphelele kanye namandla okuthwala umthwalo we-beam.
Ukugcina insimbi ye-crane beam kulula uma kuqhathaniswa nezinye izinhlobo zemishini yokwakha.Ukuhlolwa okuvamile kunconywa ukuhlola noma yiziphi izimpawu zokuguga, ukulimala, noma ukuwohloka kwesakhiwo.Uma kutholwa noma yiziphi izinkinga, kufanele zilungiswe ngokushesha ukuze kuvinjelwe ukuwohloka okwengeziwe futhi kuqinisekiswe ukusebenza okuphephile kwe-crane.
