Rail Fishplate Fastening System
CovRailway Fishplate(tseem hu ua kev sib koom ua ke lossis splice bar) yog cov hlau txuas txuas txuas hauv cov khub mus rau sab ntawm cov tsheb ciav hlau uas nyob ib sab kawg los ua ib qho kev sib txuas txuas ntxiv. Ua los ntawm cov qib carbon steel suav nrog 45 # thiab 50 #, cov phiaj no muaj cov kab xev sab saum toj thiab hauv qab uas cuam tshuam rau lub taub hau tsheb ciav hlau thiab ko taw thaum bolts tau nruj, ua kom muaj kev ruaj ntseg zoo.
Technical Specifications:
| Hom tsis ua hauj lwm | Qhov Tseem Ceeb | Yam ntxwv nta | Txoj kev tiv thaiv | Caij nyoog txawv |
|---|---|---|---|---|
| Upper -Tswj Fatigue | Fretting ntawm sab saum toj kev sib cuag | Dub oxidation cheeb tsam ntawm tawg keeb kwm; micro-fissures los ntawm deformation nto | Txo kev sib txhuam coefficient; txhim kho nto tiav | Xyoo - puag ncig |
| Lower -Qhov Ncauj Ncauj | High tensile stress ntawm 3rd/4th bolt qhov | Kev nthuav tawm nrawm dua; thaj chaw yas loj dua | Txhim kho bolt torque; txo rail kis | Peaks nyob rau lub caij ntuj no |
| Brittle Fracture | Coarse grain loj (ASTM 1-2) | Cleavage facets; tsawg kawg yas deformation; ua tsis tiav ntawm 5-10mm tawg | Kev tswj xyuas nruj; zoo -grain kho cua sov | Sudden, tsis ceeb toom |
| Corrosion qaug zog | Ntug hiav txwv / qhov av ib puag ncig | Ntau qhov chaw pib tawg los ntawm pitting | Kub-dip galvanizing; stainless hlau xaiv | Accelerated nyob rau hauv humidity |
| Fretting Hnav | Micro- txav ntawm qhov chaw sib cuag | Deformation ntawm qhov chaw; oxide khib nyiab; kev sib txhuam- ua rau muaj kev puas tsuaj | Nce clamping quab yuam; rwb thaiv tsev | Kev vam meej tsis tu ncua |
Installation & Maintenance Perspective:
- Fishplate tsis ua haujlwm suav txog kwv yees li 50% ntawm kev tsheb ciav hlau sib tsoo; Xyoo 1987 Lanzhou kab kev sib tsoo tshwm sim los ntawm kev sib tsoo ntses thiab tsheb ciav hlau tawg ua rau muaj kev puas tsuaj, hluav taws kub, thiab kev cuam tshuam 20-teev.
- Cov kab nrib pleb tshwm sim los ntawm fretting qaug zog ntawm cov ntses phaj thiab rail kev sib cuag qhov chaw, tsav los ntawm micro- kev co, kev sib txhuam hnav, thiab clamping quab yuam poob- peb yam tseem ceeb: kev sib txhuam coefficient, kev sib cuag siab, thiab plam amplitude
- Lub caij ntuj no tsis ua haujlwm nce ntxiv vim qhov loj ntawm cov tsheb ciav hlau qhov sib txawv tsim kom muaj zog tensile ntxiv ntawm 3rd thiab 4th bolt qhov
Kev Saib Xyuas & Kev Pom Kev Ua Haujlwm
- Nplhaib- zoo li tus tsim: sab saum toj thiab hauv qab qhov chaw taper sab hauv los tsim kev sib haum xeeb txawm tias bolts tau nruj, wedging khov kho tiv thaiv lub taub hau hauv qab thiab kev tsheb ciav hlau sab saum toj
- Txo lub sijhawm kawg ntawm kev khoov ntawm cov tsheb ciav hlau los ntawm 40% piv rau cov ntu tsis sib koom, faib cov khoom siv hluav taws xob hla kev sib txuas
- Bolt qhov geometry: elliptical counter-sunk qhov tiv thaiv bolt tig thaum zawm; 8.8 qib siab- lub zog bolts muaj ob lub nplhaib tsa ntawm lub taub hau rau kev txheeb xyuas, qib 10.9 muaj lub taub hau tiaj tus
