Umhlinzeki waseChina unikeza imvume yentengo yamamodeli wesitimela we-AllGB
Ukuthuthukiswa kweI-GB Standard Steel Railingalandelwa emuva ekuqaleni kwekhulu le-19. Ngaphambi kokusetshenziswa kwensimbi, ojantshi bakhiwa kusetshenziswa ama-cast Iron Rail. Kodwa-ke, le mizila yayithambekele ekuqhekekeni nasekuhleleni ngaphansi kwemithwalo esindayo, kunciphisa ukusebenza kahle nokuphepha kokuhamba kwesitimela.
Inqubo Yokukhiqiza Umkhiqizo
Ukuguqulwa kusuka ku-cast anron toUjantshi wesitimelakwenzeka kancane kancane emashumini ambalwa eminyaka. Maphakathi nekhulu le-19, onjiniyela baqala ukuzama ngojantshi bensimbi eyenziwe, ababehlala isikhathi eside futhi bencane kakhulu ngokungezwani naphansi kwe-cast rafst. Kodwa-ke, i-Iron yensimbi yayisenokulinganiselwa kwayo ngokuya ngamandla nokuqina.
Ngawo-1860s, kwasungulwa inqubo ye-Bessemer, evunyelwe ukukhiqizwa kwensimbi ephezulu. Le nqubo yayihilela ukushaya umoya ngensimbi ebilisiwe ukususa ukungcola futhi ikhiqize insimbi ngamandla aphezulu nokuqina.
Ukwethulwa Kwensimbi Rails kuguqulwe ukuhanjiswa kwesitimela. Ujantshi wensimbi wakwazi ukubekezelela imithwalo esindayo kanye nesivinini esiphakeme, okuholela ekusebenzeni kahle nasekuthandweni kwezinhlelo zesitimela. Ngokuqina kwemija yensimbi, izindleko zokulungisa kanye nesikhathi sokuphumula zincishiswe kakhulu, zivumela imisebenzi ethembekile futhi eqhubekayo yesitimela.
Kusukela kwethulwa ngojantshi wensimbi, kuye kwaba nentuthuko eqhubekayo emasusi akhiqizwayo ensimbi kanye nokwenziwa kwesitimela. Ama-alloys ensimbi anezakhiwo ezithile, njengokumelana okuphezulu nokuphikiswa kokugqwala, athuthukiswe ukuze ahlangabezane nezidingo zokuhamba kwezitimela zesitimela zanamuhla.
Namuhla, ujantshi wensimbi uyaqhubeka nokuba ngukukhetha okuyisisekelo kokwakhiwa kwesitimela ngenxa yamandla abo, ukuqina, nokusebenza kwezindleko. Bathuthukiswa ngokuqhubekayo ukuze bahlangabezane nezidingo ezandayo zemboni yezokuhamba.

Ukupakisha nokuthumela
Ukwenza ngcono i-GB Standard Steel Rail Design Idizayini Yesigaba Sezingxenye nayo ingenye yezindlela zokwenza ngcono ukuqina nokugqoka.
Esigabeni sekhanda lesitimela sojantshi wokuqala, indawo yokunyathela imnene, futhi ama-arcs ane-radius emincane asetshenziswa ezinhlangothini zombili. Kuze kube yi-1950s no-1960s, kwatholakala ukuthi kungakhathalekile ukwakheka kwekhanda lesitimela kwaqala, ngemuva kokugqokwa kwamasondo ezitimela, ukwakheka kwesitimela esiqongweni sangemuva kwayo yonke into, kanye nemisebe ye I-arc nhlangothi zombili yayimkhulu. Ukulingiswa kokuhlola kutholakale ukuthi ukubonwa kwekhanda lesitimela kuhlobene nengcindezi yokuxhumana ngokweqile yesondo le-wheel-jail e-fillet yangaphakathi yekhanda lesitimela. Ukuze anciphise ukulimala kwezitimela, wonke amazwe ashintshile ukwakheka kwe-arc yekhanda lesitimela ukunciphisa ipulasitiki deformation.
Okokuqala, amazwe alandele umgomo onjalo ekwakhiweni kwekhanda le-GB Standard Standard Steel Rail Lika: njenge-59.9kg / m ujantshi e-United States, i-Rail Head Arc yamukelwa u-R254-R31.75-R9.52; I-65KG / M Rail of the Overe Soviet Union, i-Rail Head Arc yamukela u-R300-R80-R15; I-UIC 60KG / M Rail, i-Rail Head arc yamukela u-R300-R80-R13. Kungabonakala kulokhu okungenhla ukuthi isici esiyinhloko sokwakhiwa kwengxenye yekhanda lesitimela yesimanje ukusetshenziswa kwama-curve ayinkimbinkimbi kanye ne-radii emithathu. Ngasohlangothini lwekhanda lesitimela, umugqa oqondile onesihloko esincane bese kuthathwa indawo ebanzi, futhi ithambeka lomugqa oqondile ngokuvamile 1: 20 ~ 1: 40. Umugqa oqondile onomthambeka omkhulu uvame ukusetshenziswa emhlathini ophansi wekhanda lesitimela, futhi umthambeka ngokuvamile u-1: 3 kuya ku-1: 4.
Okwesibili, endaweni yoshintsho phakathi kwesitimela sensimbi ejwayelekile ye-GB kanye nokhamuzi bezitimela, ukuze kuncishiswe imifantu ebangelwa ukugxila kwengcindezelo futhi kwandise ukumelana kwengcindezelo phakathi kwe-FishPlate kanye nojantshi, ijika eliyinkimbinkimbi lisetshenziswa nasendaweni yoshintsho phakathi Ikhanda lesitimela kanye nokhamizi bezitimela, futhi ukwakheka okukhulu kwe-radius kwamukelwa okhalweni. Isibonelo, u-UIC's 60kg / m wesitimela usebenzisa u-R7-R35-R120 kwindawo yokuguqula phakathi kwekhanda lesitimela nokhalweni. I-60KG / M CALICT isebenzisa u-R19-R19-R500 engxenyeni yenguquko phakathi kwekhanda lesitimela nokhalweni.
Okwesithathu, endaweni yoshintsho phakathi kokhandi lwesitimela kanye ne-kajaja elingezansi, ukuze kufinyelelwe kuguquko olubushelelezi lwesigaba, ukwamukelwa okuyinkimbinkimbi yejika, futhi ukuguquka kancane kancane kuhlangene kahle nomthambeka we-kajaja ongezansi. Njengo-UIC60KG / M Rail, ukusebenzisa u-R120-R35-R7. IJapan's 6kg / M Rail isebenzisa u-R500-R19. I-China's 60KG / M Rail isebenzisa u-R400-R20.
Okwesine, phansi kwengxenye yesitimela kuyisicaba, ukuze isigaba sibe nokuqina okuhle. Ubuso bokugcina bojantshi ngaphansi konke ngakwesokunene, bese buyindilinga nge-radius encane, imvamisa u-R4 ~ R2. Uhlangothi lwangaphakathi lwesitimela ngezansi luvame ukuklanywa ngamasethi amabili wemigqa e-oblique, ezinye ezamukeli ukuthambeka kabili, futhi ezinye zamukela ukuthambeka okukodwa. Isibonelo, i-UIC60GG / M Rail addow 1: 275 + 1: 14 umthamo ophindwe kabili. IJapan's 6kg / M Rail addow 1: 4 Ukuthambeka okukodwa. I-China's 60kg / M Rail addow 1: 3 + 1: 9 Ukuthambeka kabili.
