UKUPAKISHA NOKUTHUMELA
Ukuphucula uyilo lwe-GB Standard Steel Rail head section kukwayindlela enye yokuphucula ukuqina kunye nokumelana nokuguguleka.
Kwicandelo lentloko yerail yomzila wokuqala, umphezulu we-tread uthambile, kwaye ii-arcs ezine-radius encinci zisetyenziswa kumacala omabini. Kude kube yiminyaka yoo-1950 noo-1960, kwafunyaniswa ukuba nokuba yayinjani na imo yentloko yerail eyayiyilwe ekuqaleni, emva kokuguguleka kwamavili esitimela, imo ye-tread ephezu komzila yayiphantse ibe yingqukuva, kwaye i-radius ye-arc kumacala omabini yayinkulu kakhulu. Uvavanyo lokulinganisa lufumanise ukuba ukuxobuka kwentloko yerail kunxulumene noxinzelelo olukhulu loqhagamshelwano lwe-wheel-rail kwi-fillet yangaphakathi yentloko yerail. Ukuze kuncitshiswe umonakalo wokususwa kwerail, onke amazwe atshintshe uyilo lwe-arc yentloko yerail ukuze kuncitshiswe ukuguqulwa kweplastiki.
Okokuqala, amazwe alandele umgaqo onjalo kuyilo lwe-GB Standard Steel Rail head tread: i-arc ye-rail top tread ihambelana nobukhulu be-wheel tread kangangoko kunokwenzeka, oko kukuthi, ubungakanani be-tread arc, njengomzila we-59.9kg/m e-United States, i-rail head arc yamkelwe njenge-R254-R31.75-R9.52; i-65kg/m rail ye-Soviet Union yangaphambili, i-rail head arc yamkela i-R300-R80-R15; i-UIC 60kg/m rail, i-rail head arc yamkela i-R300-R80-R13. Kuyabonakala koku kungasentla ukuba uphawu oluphambili loyilo lwecandelo le-rail head yanamhlanje kukusetyenziswa kwee-curves ezintsonkothileyo kunye nee-radii ezintathu. Kwicala le-rail head, kwamkelwa umgca othe tye onomphezulu omxinwa kunye nezantsi ebanzi, kwaye i-slope yomgca othe tye ngokubanzi yi-1:20~1:40. Umgca othe tye onethambeka elikhulu udla ngokusetyenziswa kumhlathi ongezantsi wentloko yereyili, kwaye ithambeka ngokubanzi liyi-1:3 ukuya kwi-1:4.
Okwesibini, kwindawo yokutshintsha phakathi kwe-GB Standard Steel Railhead kunye nesinqe sereyile, ukuze kuncitshiswe iintanda ezibangelwa kukuxinana koxinzelelo kunye nokwandisa ukumelana kokungqubana phakathi kwe-fishplate kunye nesinqe, igophe elintsonkothileyo likwasetyenziswa kwindawo yokutshintsha phakathi kwentloko yereyile kunye nesinqe sereyile, kwaye uyilo olukhulu lweradiyumu luyasetyenziswa esinqeni. Umzekelo, ireyile ye-UIC ye-60kg/m isebenzisa i-R7-R35-R120 kwindawo yokutshintsha phakathi kwentloko yereyile kunye nesinqe. Ireyile yaseJapan ye-60kg/m isebenzisa i-R19-R19-R500 kwindawo yokutshintsha phakathi kwentloko yereyile kunye nesinqe.
Okwesithathu, kwindawo yokutshintsha phakathi kwesinqe sikaloliwe kunye nezantsi likaloliwe, ukuze kufezekiswe utshintsho olugudileyo lwecandelo, kwamkelwa uyilo oluntsonkothileyo lwegophe, kwaye utshintsho oluhamba kancinci luqhagamshelwe kakuhle nomthambeka wezantsi likaloliwe. Njengomzila we-UIC60kg/m, kukusetyenziswa i-R120-R35-R7. Umzila we-60kg/m waseJapan usebenzisa i-R500-R19. Umzila we-60kg/m waseTshayina usebenzisa i-R400-R20.
Okwesine, umzantsi wesiseko sereli uthe tyaba, ukuze icandelo libe nozinzo oluhle. Isiphelo somzantsi wereli sikwii-engile zasekunene, size emva koko sijikelezwe ngeradiyumu encinci, ngesiqhelo i-R4 ~ R2. Icala elingaphakathi lomzantsi wereli lidla ngokuyilwa ngeeseti ezimbini zemigca engqindilili, eminye yayo ithatha ithambeka eliphindwe kabini, kwaye eminye ithatha ithambeka elinye. Umzekelo, ireli ye-UIC60kg/m isebenzisa ithambeka eliphindwe kabini eliyi-1:275 + 1:14. Ireli yaseJapan eyi-60kg/m isebenzisa ithambeka elinye eliyi-1:4. Ireli yaseTshayina eyi-60kg/m isebenzisa ithambeka eliphindwe kabini eliyi-1:3 + 1:9.
