Txoj kev tsheb ciav hlauyog ib qho tseem ceeb ntawm txoj kev tsheb ciav hlau, thiab nws txoj haujlwm yog coj lub tsheb ciav hlau lub log mus rau pem hauv ntej los ntawm kev tiv thaiv lub zog loj ntawm lub log. Steel rail yuav tsum muab du, ruaj khov thiab nruam dov nto rau lub tsheb ciav hlau dhau lub log. Nyob rau hauv hluav taws xob railway los yog tsis siv neeg thaiv seem, railway khiav kuj yuav siv tau raws li ib tug khiav Circuit Court.
Yuav ua li cas xam qhov hnyav rail?
Txhawm rau xam qhov hnyav ntawm kev tsheb nqaj hlau, koj pom qhov hnyav ntawm ib chav tsev ntev (xws li phaus ib lub yard lossis kilograms ib meter) rau ib qho kev tsheb ciav hlau tshwj xeeb (piv txwv li, 115RE, 52kg), tom qab ntawd muab tag nrho qhov ntev uas xav tau rau koj txoj kev taug; lub tsheb ciav hlau qhov hnyav ntsuas qhia nws lub zog rau qag loads thiab ceev. Rau kev xa khoom, koj suav qhov hnyav (lub cev) lossis qhov hnyav (ntim) siv L x W x H.
Yam tseem ceeb cuam tshuam rau Rail Luj
Qhov yuav tsum tau rail hnyav rau ib txoj kev nyob ntawm:
- Axle Load: Cov tsheb ciav hlau hnyav dua yuav tsum tau hnyav dua.
- Tsheb ciav hlau ceev: siab dua speeds xav kom muaj zog, hnyav rail.
- Track Gauge: Qhov kev ncua deb ntawm cov ntsia hlau.
- Ballast Cushion: Qhov tob ntawm pob zeb hauv qab cov neeg pw tsaug zog.
Hom Tsheb Rail
Steel rail profiles muaj ib lub taub hau rau saum. Lub vev xaib txhawb nqa lub taub hau thiab yog qhov sib piv thinner. Nyob rau hauv lub hauv paus ntawm lub tivthaiv yog ko taw uas rests ntawm txoj kev.
- Bullhead profiles muaj qhov sib npaug sib npaug ntawm lub taub hau thiab ko taw ntawm cov khoom. Lub tswv yim tom qab cov khoom siv bullhead tau npaj los pab rov siv dua. Txawm li cas los xij, qhov tsim tiag tiag tsis muaj qhov yuav tsum tau ua kom muaj txiaj ntsig los pab txhawb kev rov siv dua thiab koom nrog kev tsim kho thiab kho cov nqi ntau. Pav ca- cov kev daws teeb meem hauv qab tau hloov qhov kev tsim kho no.
- Pav ca -cov kab hauv qab lossis flanged T- cov kab hauv North America muaj qhov dav dua, tiaj tus taw ntawm lub hauv paus. Qhov profile asymmetrical tam sim no yog cov khoom lag luam tshaj plaws thoob ntiaj teb.
- Grooved rails muaj cov qauv troughed, los yog flangeway, ntawm lub taub hau. Lub log flanges nyob rau hauv lub flangeway thaum lub sij hawm seem ntawm lub taub hau yog load bearing. Grooved rails yog qhov zoo tagnrho rau tramways nthuav qhia kev txwv ntawm qhov chaw muaj los tso ib txoj kev tsheb ciav hlau tshwj xeeb.
Txij xyoo 2008,GNEE RAILtau muab steel rails ntawm ntau qib sib txawv rau ntau tshaj 18 xyoo, steel rails los ntawm GNEE yog heev recommened nyob rau hauv Tuam Tshoj thiab txawv teb chaws.Wtih txiav ntug cov cuab yeej, GNEE ua tau zoo steel rails raws li cov kev cai ntawm feem ntau lub teb chaws. Standard rail, lub taub hau hardened rail, hnyav rail, lub teeb rail, crane rail thiab lwm yam yog tag nrho cov muaj nyob ntawm no, raws li ib tug ntawm cov Tuam Tshoj lub ntsiab rail tsum, GNEE RAIL tau ua hauj lwm rau muab kev lag luam ntsuab railway khoom thoob plaws lub ntiaj teb no.
