Ua rau thiab kho cov txheej txheem ntawm Rail Joint Misalignment
Dab tsi yog misalignment ntawm ib qho kev sib koom ua ke, thiab nws ob pawg loj yog dab tsi?
Misalignment ntawm ib qho kev sib koom ua ke yog hais txog txoj kab ntsug lossis kab rov tav misalignment ntawm qhov kawg ntawm ob txoj hlua ntawm qhov sib koom ua ke. Nws muab faib ua ntsug misalignment (siab dua qis) thiab kab rov tav misalignment (sab laug thiab sab xis). Misalignment cuam tshuam qhov txuas ntxiv ntawm cov ntsia hlau, tsim cov kauj ruam cuam tshuam, thiab yog qhov ua rau muaj kev puas tsuaj loj ntawm kev sib koom ua ke.
Dab tsi yog qhov ua rau misalignment ntawm cov pob qij txha?
Tsis txaus bolt torque lossis looseness; tsis zoo nyob nruab nrab ntawm lub phaj thiab lub tsheb ciav hlau; hnav, crushing, thiab deformation ntawm txoj kev tsheb ciav hlau xaus; kev tsis sib haum ntawm lub txaj txaj; pw tsaug zog tsis zoo ruaj ntseg; tsis zoo tamping; kev quab yuam ntau dhau ntawm cov ntu nkhaus ua rau kev tsheb nqaj hlau tsis raug; kev sib xyaw ntawm cov tsheb qub thiab tshiab; hom kev tsheb ciav hlau tsis sib haum; thiab installation positioning yuam kev.
Dab tsi yog qhov phom sij ntawm misalignment ntawm cov pob qij txha rau kev khiav thiab tsheb ciav hlau?
Misalignment ua rau muaj kev cuam tshuam zoo, ua rau bolt shearing, fishplate breakage, thiab qaug zog tawg ntawm lub caij nplooj ntoos hlav clips; exacerbating rail kawg crushing, spalling, thiab core puas; ua rau pw tsaug zog puas tsuaj thiab taug qab txaj pulverization; ua rau muaj tsheb sib tsoo, kev vibration, thiab suab nrov, thiab thaum muaj xwm txheej hnyav, yuav tsum tau txwv ceev.
Dab tsi yog cov txheej txheem thiab kev tso cai txwv rau misalignment hauv cov pob qij txha?
Raws li railway engineering txuj ci, txoj kab ntsug thiab kab rov tav misalignment ntawm cov pob qij txha ntawm cov kab tseem ceeb yuav tsum tsis pub tshaj 0.5 hli; rau cov chaw nres tsheb ciav hlau thiab cov kab nruab nrab, nws yuav tsum tsis pub tshaj 1 hli; thiab rau siab -ceev thiab ballastless khiav seem, nws yuav tsum tau tswj tsis pub dhau 0.3 hli. Ib qho kev sib txawv tshaj qhov kev txwv no yuav tsum raug kho.
Dab tsi yog qhov kev ntsuas tseem ceeb rau kev tsis sib haum xeeb hauv kev tsheb ciav hlau?
Tighten los yog hloov cov bolts sib koom ua ke kom ntseeg tau tias lub zog ua tau raws li tus qauv; grind los yog welded lub tsheb ciav hlau xaus kom rov qab smoothness; tampe, thaj, thiab kho lub txaj khiav kom tshem tawm qhov khoob; hloov deformed los yog hnav fishplates; thiab txhim kho txoj kev tsheb ciav hlau kom zoo los tswj kev tsheb ciav hlau nthuav dav thiab nkag mus.
