Qhov Kev Sib Koom Tes Uas Tau Txais 115RE thiab TR57 Rails?
Xaiv qhov kev sib koom ua ke kom raug (keeb kwm hu ua fishplate) yog qhov tseem ceeb rau kev tswj xyuas kev sib tw, kev thauj mus los, thiab kev nyab xeeb tag nrho. Cov 115 RE rail (115 lb/yd) yog ib qho ntawm cov kev tsheb ciav hlau siv dav hauv North America raws li AREMA (American Railway Engineering thiab Maintenance- ntawm -Txoj Kev Koom Tes) cov qauv. Hauv kev lag luam thoob ntiaj teb, tshwj xeeb hauv South America, tib qhov profile no feem ntau raug xaiv los uaTR 57 ua(xws li kwv yees li 57 kg / m). Vim hais tias cov profiles no sib koom zoo tib yam geometry, lawv cov kev cai bar sib koom ua ke tau zoo heev.
Phau ntawv qhia no tshuaj xyuas cov kev sib koom ua ke tshwj xeeb tsim rau 115RE thiab TR57 rails, lawv cov kev qhia tshwj xeeb, thiab cov kev xaiv tseem ceeb rau cov phiaj xwm kev tsheb ciav hlau.
1. Nkag siab txog kev sib tw: 115RE thiab TR57 Rails
115RE rail seem yog txhais los ntawm AREMA specifications, thaum lub TR57 lub npe yog feem ntau siv nyob rau hauv metric -raws li systems raws li zoo sib xws seem tsis. Lub cev ntoo khaub lig- ntu ntawm ob txoj kab tsheb ciav hlau yog tus cwj pwm los ntawm:
| Loj | Rail qhov siab (mm) | Hauv qab dav (mm) | Lub taub hau dav (mm) | Web Thickness (hli) | Qhov hnyav (kg / m) |
| 90 lb ib 90ARA-A (TR45) | 142.9 | 130.2 | 65.1 | 14.3 | 44.65 |
| 100 lb 100 RE | 152.4 | 136.5 | 68.3 | 14.3 | 50.34 |
| 1 15 lb115 RA(TR57) | 168.3 | 139.7 | 69.1 | 15.9 | 56.9 |
| 119 Ib 119 RE | 173.1 | 139.7 | 67.5 | 15.9 | 58.86 |
| 132 Ib 132 RE | 180.9 | 152.4 | 76.2 | 16.6 | 65.58 |
| 133 Ib | 179.39 | 152.4 | 76.2 | 17.46 | 66.1 |
| 136lb 136RE (TR68) | 185.7 | 152.4 | 74.6 | 17.5 | 67.5 |
| 141 Ib 141 RE | 188.91 | 152.4 | 77.79 | 17.46 | 69.94 |
Vim tias qhov kev nuv ntses qhov siab (qhov chaw nruab nrab ntawm lub hauv qab ntawm lub taub hau tsheb ciav hlau thiab sab saum toj ntawm lub hauv paus kev tsheb nqaj hlau) zoo ib yam rau ob qho tib si 115RE thiab TR57 rails, cov tuav sib koom tsim los rau 115RE profile feem ntau ua tau zoo nrog TR57 rails.
2. AREMA Standard Rail Joint – 115 Rail Joint Bar
Lub AREMA 115RE Rail Joint Bar (tseem hu ua fishplate lossis splice bar) yog ib qho tseem ceeb ntawm txoj kev tsim los txuas ob ntu ntawm 115 lb / yd tus qauv tsheb ciav hlau. Los ntawm kev ruaj ntseg lub vev xaib kev tsheb ciav hlau nrog cov bolts, cov tuav no ua kom muaj kev sib raug zoo, pab txhawb kev hloov ntawm lub log tsheb, thiab tswj xyuas tag nrho cov kev ruaj ntseg. Lawv tau siv dav thoob plaws North American freight kab, industrial sidings, thiab luv - kab railroads.
Cov kab sib koom ua ke tuaj yeem hloov kho raws li kev ua haujlwm tshwj xeeb ntawm ntu kev taug qab:
- Qhov Configurations:Muaj nyob rau hauv 4- qhov (24-nti) rau cov qauv siv thiab 6-qhov (36-nti) rau kev siv lub hauv paus lossis hnyav siv los txhim kho cov khoom xa tawm.
- Qhov Geometry:Nws tuaj yeem tsim nrog lub voj voog lossis oval qhov.
- Hom tshwj xeeb:Cov kev xaiv muaj xws li cov qauv, insulated, los yog customized designs rau tej qhov project xav tau.
- Kev sib haum xeeb Bars:Cov tuav tshwj xeeb muaj los txuas rau 115RE profile rau qhov sib txawv ntawm cov tsheb ciav hlau thaum lub sijhawm kho lossis hloov kho.
| Standard Drilling | 3-1/2 "X 6" los yog 3-1/2 "X 6" X 6" nrog 1-1/8 "dia. qhov |
| Joint Bar Length | 24 "los yog 36" |
| 4-Hole Joint Bar Nyhav (tsis muaj kho vajtse) | 68 lbs / np |
| 4-Hole Joint Bar Nyhav (nrog kho vajtse) | 76 lbs / np |
| 6-Qhov Sib Txuas Bar Nyhav (tsis muaj kho vajtse) | 102 lbs / np |
| 6-Qhov Sib Txuas Bar Nyhav (nrog kho vajtse) | 110 lbs/pr |
| Taug qab Bolt | 1" X 6" |
3. Kev txiav txim siab tseem ceeb rau kev xaiv thiab kev teeb tsa
Thaum muab cov khoom sib koom ua ke rau 115RE lossis TR57 lem, ntau yam yuav tsum tau txiav txim siab kom muaj kev ruaj ntseg, ntev - txuas mus ntev:
- Standard vs. Compromise Joint Bars:Yog tias txuas 115RE rail mus rau lwm qhov chaw (xws li 132RE lossis 100RE rail), tsis tuaj yeem siv tus qauv sib koom ua ke. Ib qho tshwj xeeb kev sib koom ua ke bar (cov kauj ruam sib koom ua ke) yuav tsum tau siv los kho qhov chaw khiav thiab ntsuas lub ntsej muag ntawm lub taub hau sib txawv.
- Insulated Joint Bars:Rau cov ntu uas siv cov kab hluav taws xob khiav rau kev taw qhia, cov kab hluav taws xob sib koom ua ke (xws li polyurethane-coated steel lossis fiberglass-bonded matrix) yuav tsum tau tiv thaiv hluav taws xob tam sim no los ntawm kev sib koom ua ke. Cov no yuav tsum tswj hwm tib qhov profile kom haum raws li tus qauv steel tuav.
- Qhov Punching / Drilling Configurations:Xyuas kom lub qhov sib nrug (xws li qauv) ntawm qhov sib koom ua ke sib raug zoo nrog cov ua ntej -drilled qhov nyob rau hauv txoj kev tsheb ciav hlau xaus. Kev sib tsoo tsis sib haum tuaj yeem ua rau bolt shear lossis localized rail web tawg.
Cov lus nug nquag nug (FAQ)
Q1: Dab tsi yog qhov txawv ntawm 115RE rail thiab TR57 rail?
A: Nominally, lawv sawv cev rau tib qhov profile. 115RE yog qhov kev xaiv raws li North American AREMA cov qauv, thaum TR57 yog ib qho kev ntsuas - sib npaug (suav txog 57 kg / m) nquag siv hauv South American thiab qee qhov kev qhia hauv European.
Q2: Dab tsi ntawm cov hlau feem ntau yog siv rau 115RE sib koom ua ke?
A: Lawv feem ntau yog tsim los ntawm kub- ua haujlwm, quenched carbon steel raws li AREMA specifications los xyuas kom meej txaus tensile lub zog thiab qaug zog tiv thaiv nyob rau hauv cyclic loading.
Q3: Puas yog 115RE sib koom ua ke yuav tsum tau tshwj xeeb bolts?
A: Yog lawm, lawv feem ntau yog tsim los kom haum raws li tus qauv oval-caj dab los yog elliptical- caj dab taug kev bolts, feem ntau yog 1 nti lossis 1-1/8 ntiv hauv txoj kab uas hla, nrog rau lub caij nplooj ntoos hlav hnyav hnyav los tiv thaiv kev xoob.
