Rail Fishplate Fastening System
CovRailway Fishplate(tseem hu ua kev sib koom ua ke lossis splice bar) yog ib qho khoom siv sib txuas uas tso cai rau cov hlua sib koom ua ke ua tus nqaj txuas ntxiv nyob rau hauv kev thauj khoom los ntawm kev faib cov kev ntxhov siab hla kev sib txuas bolted es tsis yog tsom rau lawv ntawm txoj kev tsheb ciav hlau. Tsim los ntawm cov qib carbon steel suav nrog 45 #, 50 #, thiab 55 # nrog lub zog tensile xws li 375 MPa (Q235) txog 785 MPa (55 #), cov phaj no muaj cov kab sib txuas sab saum toj thiab hauv qab uas tawm tsam lub taub hau thiab ko taw thaum bolts tau nruj.
Technical Specifications:
| Txuj | Khoom Qib | Tensile zog Rm | Yield zog | Elongation | Hom Rail Sections | Daim ntawv thov |
|---|---|---|---|---|---|---|
| TB/T2345-2008 (Tuam Tshoj) | 55 # hlau | Ntau dua lossis sib npaug li 785 MPa | Ntau dua lossis sib npaug li 520 MPa | Ntau dua lossis sib npaug li 9% | 43, 52, 60, 75 kg | Hnyav-lav mainline |
| UIC864-4/8 (Tebchaws Europe) | 40 # hlau | 550-650 MPa | N/A | Ntau dua lossis sib npaug li 18% | UIC54, UA 60 | European networks |
| DIN5902 (Lub teb chaws Yelemees) | Q235/Q295 | Ntau dua lossis sib npaug li 375 MPa | Ntau dua lossis sib npaug li 235 MPa | Ntau dua lossis sib npaug li 21% | S30-S49 kab | Lub teeb / nruab nrab kab |
| BS47-1 (British) | 40 # hlau | 550-650 MPa | N/A | Ntau dua lossis sib npaug li 18% | BS75A -BS113A | UK/Commonwealth |
| AREMA (North America) | 50 # hlau | 550-650 MPa | N/A | N/A | 115RE-141 TSI | US railroads |
Installation & Maintenance Perspective:
- Suav txheem 55 # steel phaj (TB/T2345-2008): tensile Ntau dua los yog sib npaug rau 785 MPa, yield Ntau tshaj los yog sib npaug rau 520 MPa, elongation Ntau dua los yog sib npaug rau 9%, Brinell hardness 227-388 HBW
- UIC txheem ntses phaj (UIC864-4/8) siv 40 # steel: tensile 550-650 MPa, elongation Ntau dua lossis sib npaug li 18%
- DIN txheem fishplates (DIN5902) siv Q235/Q295: tensile Ntau dua los yog sib npaug rau 375 MPa, tawm los Ntau tshaj los yog sib npaug rau 235 MPa, elongation Ntau dua los yog sib npaug rau 21%
- AREMA thiab BS standard fishplates feem ntau siv 50 # steel nrog tensile 550-650 MPa
- Kev tswj cov tshuaj muaj pes tsawg leeg: 45 # steel (C 0.42-0.50%, Mn 0.50-0.80%), 50 # steel (C 0.47-0.55%, Mn 0.50-0.80%), nrog nruj P / S txwv Tsawg dua lossis sib npaug li 0.035%
Kev Saib Xyuas & Kev Pom Kev Ua Haujlwm
- Cov kab nrib pleb feem ntau pib nyob ze ntawm lub qhov ntsia hlau qhov chaw uas muaj kev ntxhov siab thaum lub sij hawm thauj khoom caij tsheb kauj vab, nthuav tawm raws ntug nuv ntses
- Hnav ntawm qhov chaw nuv ntses tsim qhov sib txawv ntawm cov phaj thiab cov tsheb ciav hlau, tso cai rau kev txav ntau dhau uas ua rau cov tsheb ciav hlau xaus
- Cov khoom siv tsis zoo lossis kev kho cua sov tsis tsim nyog ua rau tawg hauv 5-10 xyoo piv rau 20-30 xyoo rau daim phiaj
- Cov bolts xoob yog qhov tsis xws luag; bolts uas ploj lawm tshem tawm txoj kev thauj khoom thiab overload seem bolts los ntawm 17-25%
