Yintoni i-Structure Crane Beam?
Iintsimbi zentsimbi ze-Crane ziyinxalenye ebalulekileyo yayo nayiphi na iprojekthi yokwakha efuna ukusetyenziswa kweekhreyini.Lo mqadi ulungiselelwe ngokukodwa ukubonelela ngenkxaso kunye nokuzinza kwi-crane xa uphakamisa kwaye uhambisa imithwalo enzima.Amandla ayo kunye nokuqina kwayo kwenza kube yinto ekhethekileyo kwishishini lokwakha.
Igama elithi "steel structure crane beam" libhekisa kwilungu lesakhiwo esithe tyaba elinqumla kwiindawo ezimbini okanye ngaphezulu zenkxaso.Isebenza njengesakhelo sokuba i-crane isebenze kwaye inikeze iqonga elizinzile lokuphakanyiswa kunye nokuhamba kwezinto.Le miqadi yenziwe ngokuqhelekileyo kwintsimbi ngenxa yomlinganiselo wayo ophezulu wokulinganisa amandla, okuvumela ukwakhiwa kweenkqubo ezinkulu kunye ezisebenzayo ze-crane.
Ubume bomqadi wentsimbi yesakhiwo sentsimbi:
1.Uyilo lwebhanti yebhokisi
Enye yezona ndlela zixhaphakileyo zentsimbi ye-crane girders yi-box girder design.Uyilo lubonisa ubume obumngxuma obuxande obunika amandla abalaseleyo kunye nomthamo wokuthwala umthwalo.I-flanges ephezulu kunye nezantsi yebhokisi yebhokisi idibaniswe yi-webs ethe nkqo ukwenza isakhiwo esiqinileyo nesizinzileyo.Uyilo lwebhokisi yegirder luhlala luthandwa ngenxa yokusebenza kwayo kakuhle ekuxhathiseni ukugoba kunye nemikhosi ye-torsional, ibenza bafanelekele imisebenzi yokuphakamisa ubunzima.
Uyilo lwe-2.I-beam
Olunye uhlobo oludumileyo lwe-steel crane girder luyilo lwe-I-beam.I-I-beams, eyaziwa ngokuba yi-universal beams okanye i-H-beams, ifana neleta "I" kwi-cross-section.I-flanges ephezulu kunye nezantsi ye-I-beam idibaniswe ngama-webs amile ukuze yenze isakhiwo esiqinileyo nesizinzileyo.Uyilo lwe-I-beam luyaziwa ngokuba namandla aphezulu kumlinganiselo wobunzima, okwenza ukuba ulungele izicelo apho ukunciphisa ubunzima kubaluleke kakhulu.Ihlala isetyenziswa kwiindawo ezinendawo enyiniweyo okanye izithintelo zobude njengoko ivumela umthamo omkhulu womthwalo kuyilo olubambeneyo.
3.Iibhanti zeTruss
Ukongeza kwi-box girder kunye ne-I-beam designs, i-crane girders yensimbi iza kwezinye iifom ezifana ne-truss girders kunye ne-truss girders.Imiqadi ye-truss iquka amacandelo amaninzi adibeneyo angamanxantathu, anikezela ukuguquguquka kunye nokusebenza kakuhle ekusasazeni umthwalo.I-Lattice beams, ngakolunye uhlangothi, yenzelwe ii-webs ezivulekileyo kunye namalungu e-diagonal, okuvumela ubunzima obulula kunye nesakhiwo esingabizi kakhulu.
Emva kokuba uyilo lugqityiwe, ukuveliswa kunye nokufakwa kwentsimbi ye-crane beam kunokuqala.Inkqubo yokwenziwa ibandakanya ukusika kunye nokubumba amacandelo ensimbi ngokwemigaqo yoyilo.Ubuchwephesha be-Welding buqhele ukusetyenziswa ukudibanisa iindawo ezahlukeneyo kunye, ukuqinisekisa ukunyaniseka kolwakhiwo lomqadi.
Ngexesha lofakelo, intsimbi ye-crane beam ixhunywe ngokukhuselekileyo kwiindawo ezixhasayo, ngokuqhelekileyo zisebenzisa iibholiti okanye i-welding.Ukulungelelaniswa okufanelekileyo kunye nokulinganisa kubalulekile ukuqinisekisa ukuba i-boam isebenza ngokuchanekileyo kwaye inokuxhasa ukunyakaza kwe-crane.Ukongezelela, ukunyanzeliswa okwaneleyo kunye nokuqiniswa kunokufuneka ukunyusa ukuzinza ngokubanzi kunye nomthwalo wokuthwala umthamo we-beam.
Ukugcina umqadi we-crane yesakhiwo sentsimbi kulula xa kuthelekiswa nezinye iintlobo zezixhobo zokwakha.Ukuhlolwa rhoqo kucetyiswa ukuba kujongwe naziphi na iimpawu zokuguga, ukonakala, okanye ukuguqulwa kwesakhiwo.Ukuba kukho nayiphi na imiba efunyenweyo, kufuneka iqwalaselwe ngokukhawuleza ukuthintela ukuwohloka okungakumbi kunye nokuqinisekisa ukusebenza ngokukhuselekileyo kwe-crane.
