Rail Fishplate Fastening System
Lub Rail Fishplate, tseem hu ua kev sib koom ua ke lossis splice bar, yog ib khub, profiled steel tivthaiv bolted symmetrically mus rau ob sab ntawm adjoining rail webs los tsim kom muaj kev sib txuas txuas ntxiv ntawm kev tsheb nqaj hlau. Qhov no precision-forged fastener ua haujlwm los ntawm ntau-bolt clamping uas ua rau muaj kev sib txhuam tsis sib haum thiab shear load hloov mus thoob plaws qhov sib txawv ntawm txoj kev tsheb ciav hlau, tuav txoj kab ntsug thiab kab rov tav thaum ua kom tswj tau cov thermal txav.
Technical Specifications:
| Parameter | Standard Fishplate | Joggled Fishplate | Compromise Fishplate | Insulated Fishplate (Polymer) |
|---|---|---|---|---|
| Lub luag haujlwm tseem ceeb | Rail kawg kev twb kev txuas | Kev ntxhov siab -txo kev sib koom ua ke | Koom nrog sib txawv rail seem | Hluav taws xob rho tawm + txuas ntxiv |
| Profile yam ntxwv | Symmetrical web match | Vertically offset bolt qhov | Asymmetric profiles ntawm txhua sab | iav -fiber reinforced polymer |
| Hom Bolt Qhov | 4o6 cev | 4o6 cev | 4o6 cev | 4o6 cev |
| Tus nqi txheeb ze | 1.0 × (lub hauv paus) | 1.10-1.15× | 1.20-1.30× | 2.0-3.0× |
| Service Life Expectancy | 20+ xyoo (zoo steel) | Muab ob npaug rau txheej hauv nkhaus | Lower (kev tsheb ciav hlau tsis muaj zog tshaj plaws) | Kev tshawb fawb tsis tu ncua |
| Tej kev siv | Secondary kab, ib ntus khiav | Curves, hnyav- txoj kev tsheb khiav | Kev hloov pauv ntawm cov kab tsheb ciav hlau | Taug qab circuit territories |
| Txoj Kev Txhim Kho | Bolted clamping | Bolted clamping | Bolted clamping | Bolted (tej zaum yuav tshem tawm cov kua nplaum) |
Installation & Maintenance Perspective:
- Tapered Wedge Action:Lub phaj phaj sab saum toj thiab hauv qab ntawm lub ntsej muag taper sab hauv nrog lawv qhov ntev, tsim kom muaj kev sib txuas thaum lub bolts tau nruj, uas ua rau kom nrawm nrawm thiab ua kom muaj kev sib raug zoo nrog lub vev xaib rail.
- Load Distribution Architecture:Txhua lub log ua kom muaj kev cuam tshuam rau lub zog uas tau muab faib thoob plaws hauv ob qho kev tsheb ciav hlau, nrog rau cov phaj torqued kom zoo txo qhov kev sib koom ua ke ntawm qhov siab tshaj plaws los ntawm 40-50% piv rau cov kev tsheb ciav hlau tsis muaj kev txhawb nqa.
- Joggled Profile Design:Tshwj xeeb joggled ntses daim hlau offset bolt qhov vertically kom tsis txhob coincidence nrog rail ntsia liaj qhov rooj qhov, tshem tawm kev ntxhov siab concentration zones uas yuav txwv tsis pub propagate kab nrib pleb los ntawm lub vev xaib mus rau hauv lub taub hau rail.
Kev Saib Xyuas & Kev Pom Kev Ua Haujlwm
- Tswj cov ntsiab lus carbon:Premium fishplates siv cov hlau tua nrog 0.40-0.50% cov ntsiab lus carbon, muab qhov zoo tshaj plaws lub zog-tooj sib npaug rau kev cuam tshuam.
- Yam tsawg kawg nkaus Tensile Requirements:Cov lus qhia tshwj xeeb ua kom muaj zog tensile tshaj 690 MPa thiab elongation saum 14%, txheeb xyuas los ntawm cov ntaub ntawv pov thawj cov ntaub ntawv pov thawj.
- Hardness Optimization:Kev Pabcuam- pov thawj fishplates tuav qhov tsawg kawg nkaus 260 BHN hardness, tiv thaiv kev qaug zog puas tsuaj los ntawm kev ua kom muaj zog thiab elongation muaj peev xwm xa tau 20+ xyoo kev pab cuam lub neej piv rau 5-7 xyoo rau cov qib qis .
