Dab tsi yog qhov ntses phaj ntawm txoj kab tsheb ciav hlau?
Lub phaj phaj (los yog kev tsheb nqaj hlau sib koom ua ke, splice bar) ntawm txoj kab tsheb ciav hlau yog hlau bar, feem ntau yog hlau, uas bolts mus rau qhov kawg ntawm ob txoj kab uas nyob ib sab los koom lawv mus rau hauv ib qho kev sib txuas ntxiv, tswj kev sib tw, hloov cov loads, thiab muab kev nruj, nrog lub npe los ntawm nws cov duab zoo li tus ntses. Lawv yog qhov tseem ceeb rau txoj kev tsheb ciav hlau du thiab nyab xeeb, tiv thaiv kev sib kis ntawm kev sib kis, thiab siv rau txhua hom kev tsheb ciav hlau.
Lub luag haujlwm tseem ceeb:
- Connects Rails: Koom nrog ob txoj kev tsheb ciav hlau xaus ua ke los tsim kom ntev, txuas ntxiv mus.
- Tswj Kev Sib Tw: Tuav cov hlua hauv txoj kab rov tav thiab ntsug kom zoo.
- Hloov Loads: faib qhov hnyav thiab cuam tshuam ntawm lub tsheb ciav hlau log ntawm ib lub tsheb ciav hlau mus rau lwm qhov.
- Muab Lub Zog: Ntxiv qhov nruj rau txoj kev tsheb ciav hlau sib koom ua ke, tiv thaiv kev sib cais.
- Tso Cai Tshaj Tawm: Ua kom haum rau lub ntuj nthuav dav thiab kev cog lus ntawm cov ntsia hlau vim qhov kub thiab txias.
Cov hom tseem ceeb rau ntses daim hlau
Kev faib tawm los ntawm Cov Qauv Txheej Txheem
Raws li cov duab ntawm lub phaj thiab hom kev tsheb nqaj hlau sib koom ua ke nws haum, fishplates tuaj yeem muab faib ua:
- Standard Fishplates: Cov no muaj lub phaj tiaj tiaj nrog lub qhov ntsia hlau ntawm ob sab, tsim kom haum rau cov pob qij txha ncaj ntawm cov qauv ntsia. Qhov no yog hom siv ntau tshaj plaws (xws li feem ntau ntawm qhov hnyav- cais cov qauv hais saum toj no).
- Tshwj xeeb-Shaped Fishplates: Kuj hu ua "special fishplates," lawv cov duab yog tsim los ntawm cov ces kaum tshwj xeeb ntawm cov pob qij txha (piv txwv li, nkhaus lem) los yog cov kab sib txawv. Lawv yog siv rau cov uas tsis yog - kab lem (xws li railway curves) los yog rails nrog tshwj xeeb ntoo khaub lig-sections los xyuas kom meej smoothness ntawm cov pob qij txha.
Kev faib tawm los ntawm Cov Kev Xav Tau Ua Haujlwm
Raws li kev ua haujlwm tshwj xeeb ntawm kev khiav (xws li rwb thaiv tsev thiab lub zog siab), cov ntses tuaj yeem muab faib ua:
- Insulated Fishplates: Ua los ntawm cov ntaub ntawv insulating (xws li, iav fiber reinforced yas) los yog hlau fishplates coated nrog ib txheej insulating. Lawv yog siv nyob rau hauv kev sib koom ua ke ntawm kev tsheb ciav hlau hauv cov hluav taws xob railways los tiv thaiv hluav taws xob conductivity uas tuaj yeem cuam tshuam nrog cov teeb liab, lossis hauv cov seem uas yuav tsum tau muaj hluav taws xob cais tawm.
- Tsis yog-Insulated Fishplates: Txheem hlau ntses phaj yam tsis muaj rwb thaiv tsev, haum rau tsis yog - hluav taws xob railways lossis lem uas tsis xav tau hluav taws xob cais.
