Yuav ua li cas yog tias lub tsheb ciav hlau rub tawm sib nrug thiab koj tsis tuaj yeem tau txais cov bolts hauv?
Thaum lub tsheb ciav hlau rub tawm sib nrug vim huab cua txias lossis kev tsheb ciav hlau txav, thiab cov bolts tsis tuaj yeem rov nruab, qhov sib txawv yuav tsum raug kaw kom muaj kev nyab xeeb rov qab los. Cov txheej txheem muaj xws li cua sov txoj kev tsheb ciav hlau nrog "Hlawv-Snake" los nthuav nws, siv cov jacks los rub cov ntsia hlau ua ke, txhim kho "Dutchman" (luv rail muab tub lim), lossis hloov cov tsheb ciav hlau.
Kev Kho Thaum Muaj Xwm Ceev thiab Cov Txheej Txheem:
- Cua sov (Hlawv-Snake/Kerosene Rope):Hauv huab cua txias, kev nthuav dav yog xav tau. Ib txoj hauv kev yog muab cov roj-soaked rags los yog "Hlawv-Snake" (cov cuab yeej cua sov) nrog rau txoj kev tsheb ciav hlau kom sov nws, ua rau nws nthuav dav txaus los txuas rau qhov sib koom ua ke.
- Mechanical rub:Track jacks lossis mechanical rail expanders / pullers yog siv los rub cov tsheb ciav hlau xaus rov qab ua ke, feem ntau hu ua "tsav tsheb ciav hlau tsev".
- Dutchman / Rail Filler:Yog tias qhov sib txawv loj dhau los kaw, ib qho "Dutchman" (ib qho me me ntawm txoj kev tsheb ciav hlau txiav rau qhov loj) raug teeb tsa los sau qhov sib txawv.
- Slotted Joint Bars:Yog hais tias cov pa bolts yuav tsis haum, tshwj xeeb uas tsim slotted ob leeg tuav yuav siv tau rau ib ntus, muaj zog reinforcement.
- Rail Splints:Siv raws li kev kho ib ntus rau txuas cov pob qij txha tawg lossis sib cais, tshwj xeeb tshaj yog thaum lub tsheb ciav hlau tsis tuaj yeem kho tam sim ntawd.
Cov kev xav txog kev nyab xeeb tseem ceeb:
- Txhua qhov sib txawv tshaj 5/8 "yuav tsum tau tshuaj xyuas tam sim thiab ua haujlwm.
- Xyuas kom qhov sib koom ua ke tau txais kev txhawb nqa zoo, vim qhov teeb meem sib txawv tuaj yeem ua rau cov kab sib koom ua ke.
- Yog tias kev kho tsis tuaj yeem ua tam sim ntawd, txoj kab yuav tsum tau tiv thaiv (piv txwv li, kev txiav txim qeeb) kom tsis txhob derailment.
Dab tsi yog qhov ua haujlwm ntawm kev sib koom ua ke ntawm kev tsheb ciav hlau thiab lub nkoj railfish bolt?
Rail pob qij txha (fishplates) thiab railfish bolts txuas cov tsheb ciav hlau xaus kom muaj kev sib txuas ua ke, tso cai rau kev nthuav dav thermal thaum tiv thaiv ntsug / sab nraud. Lawv ua kom muaj kev ncaj ncees ntawm cov qauv, tiv thaiv kev tsheb ciav hlau buckling, thiab ua kom yooj yim txij nkawm, nrog cov bolts tuav cov phiaj tiv thaiv lub vev xaib rail kom muaj zog.
Kev Ua Haujlwm ntawm Rail Joint (Fishplate)
- Ua kom muaj kev txuas ntxiv:Txuas ob txoj kev tsheb ciav hlau kawg kom tso cai rau txoj kev tsheb ciav hlau du.
- Txhim kho kev sib tw:Khaws cov tsheb ciav hlau xaus ntawm tib theem ntsug thiab kab rov tav.
- Tso cai Expansion/Contraction:Muab qhov chaw rau cov ntsia hlau txav vim qhov kub thiab txias hloov.
- Txhim khu kev sib txuas:Resistant shear force thiab longitudinal / lateral loads.
- Compromise Joints:Cov pob qij txha tshwj xeeb txuas sib txawv rail profiles.
Kev ua haujlwm ntawm Rail Fish Bolt
- Fastens Cheebtsam:Kev ruaj ntseg txuas cov ntses phaj rau cov ntsia hlau.
- Tiv thaiv kev sib hloov:Feem ntau nta lub caj dab oval los tiv thaiv kev tig thaum siv lub zog.
- Ua kom ruaj ntseg:Ua ke nrog lub caij nplooj ntoos hlav ntxhua khaub ncaws kom tsis txhob xoob hauv qab vibrations.
- Siab zog:Ua los ntawm siab - carbon lossis alloy steel kom tiv taus cov khoom hnyav.
