A rail ntses phajyog ib qho cuab yeej siv zog ntxiv uas tau them nyiaj rau qhov poob ntawm cov nqaj txuas ntxiv ntawm kev tsheb ciav hlau qhov tsis sib xws, kom ntseeg tau tias kev sib koom ua ke tseem tuaj yeem muab kev nruj txaus, ruaj khov, thiab lub log thauj khoom thaum lub sijhawm ua haujlwm.GNEE RAILmuab ntses daim hlau rau GB 8–60 kg/m rails, UIC50–UIC60, DIN536 A-series crane rails, QU crane rails, JIS qauv, AS1085 rails, BS11 profiles, thiab AREMA/ASCE seem, thiab txhawb cov neeg muas zaub nrog kev sib koom ua ke layout optimization.
Cov phaj ntses ua haujlwm li cas?
Rail ntses daim hlau, los yog sib koom ua ke, yog cov hlau daim hlau bolted rau ob sab ntawm txoj kev tsheb ciav hlau xaus mus txuas rau lawv, ua kom cov txheej txheem txuas ntxiv, kev sib tw, thiab kev thauj mus los. Lawv tuav ntsug thiab sab nraub qaum ntawm cov pob qij txha thaum tso cai rau qhov tseem ceeb thermal expansion thiab contraction, tiv thaiv kev khiav buckling.
Lub luag haujlwm tseem ceeb thiab cov txheej txheem ua haujlwm:
- Txuas Rails:Paired daim hlau (ib qho ntawm txhua sab) yog bolted los ntawm kev tsheb ciav hlau lub vev xaib, tsim kom muaj kev sib koom ua ke tsis tau yooj yim me ntsis.
- Load Distribution:Ntses daim hlau hloov lub log loads ntawm ib lub tsheb ciav hlau mus rau lwm qhov, txo qhov deflection ntawm qhov sib koom ua ke.
- Expansion/Contraction:Lawv tso cai rau kev txav mus ntev ntawm cov ntsia hlau vim qhov kub hloov pauv, tsis txhob kinks lossis tawg.
- Kev sib tw:Lawv tuav cov qib thiab ntsuas (qhov deb ntawm txoj hlua) ntawm sab saum toj thiab sab, ua kom muaj kev sib tw.
Cheebtsam ntawm Fish Plate Assembly:
- Ntses daim hlau:Feem ntau yog ua los ntawm qib siab - cov hlau zoo, feem ntau nrog cov ntawv tshwj xeeb kom phim cov kev tsheb ciav hlau tshwj xeeb.
- Ntses Bolts:Siab - lub zog steel bolts (4 lossis 6 ib qho sib koom ua ke) uas tuav cov phiaj rau cov ntsia hlau.
- Caij nplooj ntoos hlav Washers / Locknuts:Cov no tiv thaiv cov bolts los ntawm loosening vim khaus vibration los ntawm cov tsheb ciav hlau hla.
Dab tsi yog qhov ntau thiab tsawg rau rail sib koom ua ke?
Common rail sib koom tuav (los yog fishplates) txuas cov tsheb ciav hlau xaus, nrog cov qauv ntau thiab tsawg feem ntau 24 lossis 36 ntiv tes ntev, muaj 4 lossis 6 lub qhov taub. Qhov loj me muaj xws li 115RE, 132RE, 136RE, 141RE, UIC60, UIC54, BS80A, thiab 43kg / 50kg / 60kg rau hnyav-cov dej num. Lawv feem ntau yog siv los ua khub los txuas cov kev sib txuas zoo ib yam, lossis raws li kev sib cuam tshuam cov pob qij txha rau cov kab sib txawv.
