Ithrekhi Yezitimela Ezisindayo Ezisetshenziswa Insimbi Yensimbi Ingxenye Eyinhloko Yethrekhi Kaloliwe kanye Nethrekhi Isekethe Q275 20Mnk Rail Steel
Izinsimbi zensimbi zivame ukukhiqizwa ngobude obujwayelekile obungamafidi angama-30, amafidi angama-39, noma amafidi angama-60, nakuba ojantshi abade bangakhiqizelwa amaphrojekthi athile.Uhlobo oluvame kakhulu lukajantshi wensimbi olusetshenziswa kujantshi wesitimela lwaziwa ngokuthi ujantshi ophansi, onesisekelo esiyisicaba kanye nezinhlangothi ezimbili ezinama-engeli.Isisindo sikaloliwe, okwaziwa ngokuthi "iphawundi," siyahlukahluka kuye ngezimfuneko ezithile zikajantshi wesitimela.
Inqubo yokukhiqiza ama-rails ensimbi ihilela izinyathelo ezimbalwa, ezihlanganisa:
- Ukulungiswa kwempahla eluhlaza: Ukukhiqizwa kwezinsimbi zensimbi kuqala ngokukhethwa nokulungiswa kwezinto ezingavuthiwe, ngokuvamile amabhilidi ensimbi ekhwalithi ephezulu.Lawa mabhilidi enziwe ngensimbi yensimbi nezinye izithasiselo, njenge-limestone ne-coke, ezincibilikiswa esithandweni esishisayo ukuze kukhiqizwe insimbi encibilikisiwe.
- Ukubunjwa okuqhubekayo: Insimbi encibilikisiwe ibe isidluliselwa emshinini wokuphonsa oqhubekayo, lapho ithelwa khona esikhunjeni ukuze kwakhe imicu emide eqhubekayo ebizwa ngokuthi ama-billet.Lawa mabhilidi ngokuvamile anonxande futhi ahlinzeka ngezinto zokuqala zenqubo yokukhiqiza ujantshi.
- Ukushisisa nokugingqika: Amabhilidi ashiswa kabusha esithandweni ukuya ezingeni lokushisa eliwavumela ukuthi akheke kalula futhi asongwe.Bese bedluliswa ochungechungeni lwezigayo eziginqikayo, ezifaka ingcindezi enkulu yokubumba amabhilidi abe yiphrofayili efiswayo kaloliwe.Inqubo yokugingqa ihilela ukuphindaphinda kaningi kokudlulisa amabhilidi ezigayweni ukuze kancane kancane awalolonge abe ojantshi.
- Ukupholisa nokusika: Ngemva kwenqubo yokugoqa, ama-rails ayapholiswa futhi asikwe ubude obudingekayo.Ngokuvamile zisikwa zibe ubude obujwayelekile obungamamitha angu-30, amafidi angu-39, noma amafidi angu-60, nakuba ojantshi abade bangakhiqizelwa amaphrojekthi athile.
- Ukuhlolwa nokwelashwa: Amareyili aqediwe ahlolwa ngokucophelela ukuze kuqinisekiswe ukuthi ayahlangabezana namazinga nemibandela yemboni.Ukuhlolwa okuhlukahlukene, okufana nezilinganiso zobukhulu, ukuhlaziya amakhemikhali, nokuhlolwa kwemishini, kwenziwa ukuze kuqinisekiswe ikhwalithi nobuqotho bamareyili.Noma yimaphi amaphutha noma ukungapheleli kuyahlonzwa futhi kunakekelwe.
- Ukwelashwa kwendawo: Ukuthuthukisa ukuqina nokumelana nokugqwala kwamareyili, bangase babhekane nezinqubo zokwelashwa ezingaphezulu.Lokhu kungahlanganisa ukusebenzisa okokuvikela, okufana nopende ovimbela ukugqwala noma ukugqugquzelwa, ukuvimbela ukugqwala nokugqwala, ngaleyo ndlela kunwebe isikhathi sokuphila samareyili.
- Ukuhlolwa kokugcina nokupakishwa: Uma ama-rails eselungisiwe futhi esephumelele ukuhlolwa kokugcina, apakishwa ngokucophelela ukuze athuthelwe ezindaweni zokwakha ujantshi.Iphakheji yakhelwe ukuvikela ojantshi kunoma yimuphi umonakalo ngesikhathi sokuthutha.
Izici
Izinsimbi zensimbi ziyingxenye ebalulekile yamathrekhi wesitimela futhi zinezici ezimbalwa ezibalulekile:
1. Amandla Nokuqina: Izinsimbi zensimbi zenziwe ngensimbi yezinga eliphezulu, ezinikeza amandla amahle kakhulu nokuqina.Ziklanyelwe ukumelana nemithwalo esindayo, ukuthinteka okungaguquki, nezimo zezulu ezimbi kakhulu ngaphandle kokuguquka okuphawulekayo noma ukulimala.
2. Ikhono Eliphezulu Lokuthwala Imithwalo: Ojantshi bensimbi bakhiwe ukuze basekele isisindo sezitimela nempahla yazo.Bangakwazi ukuphatha imithwalo esindayo futhi basabalalise isisindo ngokulinganayo, banciphise ubungozi bokwehluleka kwethrekhi noma ukuwohloka.
3. I-Wear Resistance: Izinsimbi zensimbi zinokumelana okuphezulu nokugqoka nokuhuzuka.Lokhu kubalulekile njengoba izitimela zihlala zigijima kumareyili, kubangela ukungqubuzana nokuguga ngokuhamba kwesikhathi.Insimbi esetshenziswa ekukhiqizeni ujantshi ikhethwa ngokukhethekile ngenxa yekhono layo lokumelana nokuguga nokugcina isimo sayo isikhathi eside sokusetshenziswa okuqhubekayo.
4. Ukunemba Kobukhulu: Ojantshi bensimbi bakhiqizwa ukuze bakwazi ukubekezelela ubukhulu obuqinile ukuze kuqinisekiswe ukuhambisana nokusebenza kahle nezinye izingxenye zikaloliwe, njengamajoyinti kaloliwe, othayi abaphambanayo, nezinsimbi.Lokhu kuvumela ukuhamba kahle kwezitimela eduze kwethrekhi futhi kunciphisa ingcuphe yokuphuma emzileni noma ukuphazamiseka.
5. Ukumelana Nokugqwala: Izinsimbi zensimbi zivame ukuphathwa ngezingubo zokuzivikela noma zifakwe uthayela ukuze zithuthukise ukumelana kwazo nokugqwala.Lokhu kubaluleke kakhulu ezindaweni ezinomswakama ophezulu, izindawo ezibolayo, noma ezichayeke emanzini, njengoba ukugqwala kungase kubenze buthaka ojantshi futhi kulimaze ubuqotho besakhiwo sabo.
6. Ubude besikhathi: Izinsimbi zensimbi zinesikhathi eside sokusebenza, okunomthelela ekongeni yonke kwengqalasizinda yezitimela.Ngokulungiswa okufanele nokuhlolwa ngezikhathi ezithile, ama-rails ensimbi angahlala amashumi ambalwa eminyaka ngaphambi kokudinga ukushintshwa.
7. Ukumiswa: Ojantshi bensimbi bakhiqizwa ngokuvumelana namazinga emboni kanye nokucaciswa okubekwe izinhlangano ezifana ne-American Society for Testing and Materials (ASTM) noma i-International Union of Railways (UIC).Lokhu kuqinisekisa ukuthi izinsimbi zensimbi ezivela kubakhiqizi abahlukene zingashintshwa kalula futhi zihlanganiswe ezinhlelweni ezikhona zikaloliwe.
Isicelo
Izinsimbi zensimbi zisetshenziselwa ikakhulukazi ukwakhiwa kwamathrekhi wesitimela, okuvumela izitimela ukuthutha abagibeli nezimpahla ngendlela efanele.Nokho, banezinye izinhlelo zokusebenza eziningana futhi:
1. I-Tram kanye ne-Light Rail Systems: Ama-steel rails asetshenziswa kuma-tram namasistimu wesitimela esincane ukuze aqondise amasondo ezimoto endleleni ekhethiwe.Lezi zinhlelo zivame ukutholakala ezindaweni zasemadolobheni futhi zihlinzeka ngezinto zokuhamba phakathi kwamadolobha namadolobhana.
2. Amathrekhi Wezimboni Nezezimayini: Ojantshi bensimbi basetshenziswa ezindaweni zezimboni, njengamafekthri noma izindawo zezimayini, ukuze kusekelwe ukuthuthwa kwezinto ezisindayo nezinto zokwakha.Avame ukubekwa ngaphakathi kwezindawo zokugcina izimpahla noma amayadi, axhuma izindawo zokusebenza ezihlukene noma izindawo zokugcina.
3. Amathrekhi Echweba Namatheminali: Kusetshenziswa ojantshi bensimbi emachwebeni nasematheminali ukuze kube lula ukuhamba kwempahla.Abekwe ezikhumulweni zemikhumbi noma ezindaweni zokugcina ukuze akwazi ukulayishwa kanye nokuthulula imikhumbi neziqukathi.
4. Amapaki etimu nama-Roller Coasters: Ojantshi bensimbi bayingxenye ebalulekile yama-roller coasters nokunye ukugibela epaki lokuzijabulisa.Bahlinzeka ngesakhiwo nesisekelo sethrekhi, ukuqinisekisa ukuphepha nokusebenza kahle kokugibela.
5. Ama-Conveyor Systems: Ojantshi bensimbi bangasetshenziswa ezinhlelweni zokuthutha, ezisetshenziswa ezimbonini ezihlukahlukene ukuthutha impahla noma izinto ezisetshenziswayo endleleni engaguquki.Banikeza ithrekhi eqinile nethembekile ukuze amabhande okuthutha asebenze.
6. Amathrekhi Esikhashana: Amathrekhi ensimbi angasetshenziswa njengamathrekhi esikhashana ezindaweni zokwakha noma phakathi namaphrojekthi okulungisa.Bavumela ukunyakaza kwemishini esindayo kanye nemishini, ukuqinisekisa ukusebenza kahle ngaphandle kokudala umonakalo emhlabathini ongaphansi.
