1. Puas muaj cov qauv thoob ntiaj teb rau txoj kev tsheb ciav hlau?
Yog lawm, muaj ntau yam qauv thoob ntiaj teb rau kev tsheb ciav hlau spikes los xyuas kom meej qhov sib xws thiab kev nyab xeeb. Lub International Union ntawm Railways (UIC) muaj cov qauv uas qhia cov khoom, qhov loj, lub zog, thiab kev ua haujlwm. Hauv Tebchaws Europe, EN cov qauv (piv txwv li, EN 13674) tswj kev tsheb ciav hlau txuas nrog rau spikes. Hauv Tebchaws Meskas, American Railway Engineering thiab Maintenance- ntawm-Txoj Kev Koom Tes (AREMA) tau teeb tsa cov qauv tsim thiab ua kom zoo. Cov qauv no xyuas kom meej tias spikes los ntawm cov tuam txhab sib txawv tau sib xws nrog thoob ntiaj teb kev tsheb ciav hlau thiab ua tau raws li cov qauv kev nyab xeeb.
2. Yuav ua li cas railway spikes ua nyob rau hauv cov xuab zeb suab puam ib puag ncig?
Railway spikes nyob rau hauv cov xuab zeb suab puam ib puag ncig ntsib cov kev cov nyom xws li xuab zeb abrasion thiab huab cua kub hloov. Alloy steel spikes nrog siab hnav tsis kam yog nyiam, raws li cov xuab zeb tuaj yeem hnav cov ntaub ntawv softer. Kev kho deg zoo li galvanizing pab tiv thaiv corrosion los ntawm qee zaus suab puam noo. Qhov taw tes kawg ntawm qhov ntsia hlau loj tuaj yeem txhawb nqa kom tsis txhob khoov thaum muab tso rau hauv cov neeg pw tsaug zog sib xyaw nrog xuab zeb. Kev tu tsis tu ncua yog xav tau kom tshem tawm cov xuab zeb los ntawm ib ncig ntawm cov pob zeb, vim cov xuab zeb tuaj yeem ua rau loosening. Nrog kev xaiv cov khoom tsim nyog thiab kev saib xyuas, spikes tuaj yeem ua tau zoo hauv cov suab puam.
3. Dab tsi yog qhov sib txawv ntawm txoj kev tsheb ciav hlau thiab lub tsheb ciav hlau clip?
Ib txoj kev tsheb ciav hlau dav hlau yog ib qho fastener uas txuas cov tsheb ciav hlau mus rau cov neeg pw tsaug zog ncaj qha, siv nws cov duab thiab cov khoom siv zog rau kev kho. Ib qho kev sib tw tsheb ciav hlau, ntawm qhov tod tes, yog lub caij nplooj ntoos hlav- zoo li cov khoom uas clamps lub tsheb ciav hlau mus rau lub txaj pw, feem ntau ua haujlwm nrog lub hauv paus phaj. Spikes yog qhov yooj yim dua hauv kev tsim thiab feem ntau yog siv hauv cov tsoos lem, thaum cov tsheb ciav hlau clips muab kev yooj yim dua thiab muaj nyob rau niaj hnub high - kev tsheb ciav hlau ceev. Spikes cia siab rau kev siv dag zog, thaum cov tsheb ciav hlau siv lub caij nplooj ntoos hlav nro. Lawv tsim nyog rau cov qauv sib txawv thiab kev thauj khoom.
4. Cov kev tsheb ciav hlau puas tuaj yeem siv rau hauv kev tsheb ciav hlau ib ntus?
Yog lawm, railway spikes feem ntau yog siv rau hauv kev tsheb ciav hlau ib ntus, xws li cov chaw tsim kho lossis kho xwm txheej ceev. Cov pa roj carbon steel spikes feem ntau nyiam ntawm no vim lawv cov nqi qis thiab muaj kev yooj yim. Lawv tuaj yeem ntsia tau sai thiab tshem tawm, uas yog qhov zoo rau kev siv ib ntus. Txawm li cas los xij, kev taug kev ib ntus tseem xav tau spikes kom ua tau raws li cov qauv kev siv zog los ua kom muaj kev nyab xeeb. Tom qab qhov kev khiav ib ntus tsis xav tau lawm, cov spikes tuaj yeem rov qab tau, thiab yog tias nyob rau hauv qhov zoo, rov qab siv dua hauv lwm cov haujlwm ib ntus. Qhov no ua rau spikes qhov kev xaiv ua tau zoo rau kev siv tsheb ciav hlau ib ntus.
5. Dab tsi yog qhov cuam tshuam los ntawm cov dej nag ntawm txoj kev tsheb ciav hlau?
Cov dej nag ua rau cov av noo nyob ib puag ncig ntawm txoj kev tsheb ciav hlau, ua kom cov xeb ua kom nrawm, tshwj xeeb tshaj yog rau cov pa roj carbon hlau tsis muaj hlau. Cov dej nag ntev ntev tuaj yeem nkag mus rau hauv qhov sib txawv ntawm cov ntsia hlau loj thiab cov neeg pw tsaug zog, ua rau muaj corrosion ntawm sab hauv. Rust tsis muaj zog rau qhov spike lub zog, ua rau loosening lub sijhawm. Nyob rau hauv cov cheeb tsam uas muaj dej nag hnyav, spikes nrog tiv thaiv - kev kho corrosion (xws li galvanizing) los yog stainless hlau spikes yog siv los txo cov nyhuv no. After rain, railway workers often inspect spikes to check for rust or looseness, ensuring track safety.
