1. Lub luag haujlwm tseem ceeb ntawm kev tsheb ciav hlau clamps yog dab tsi?
Railway clamps, tseem hu ua rail clips lossis rail fasteners, ua haujlwm tseem ceeb hauv kev ruaj ntseg rau cov neeg pw tsaug zog (lossis kev sib raug zoo), tuav txoj kev tsheb ciav hlau kom zoo thiab tiv thaiv kev txav mus los lossis ntev. Lawv siv lub zog qis qis rau ntawm lub hauv paus kev tsheb nqaj hlau, kom ntseeg tau tias nws nyob ruaj khov hauv qhov chaw txawm tias nyob rau hauv cov khoom hnyav thiab kev vibrations ntawm cov tsheb ciav hlau hla. Los ntawm kev faib cov zog no sib npaug thoob plaws lub txaj pw, clamps txo kev ntxhov siab ntawm ob qho tib si ntawm txoj kev tsheb ciav hlau thiab cov qauv hauv qab, txo qis hnav thiab txuas ntxiv lub neej ntawm cov khoom siv. Lawv kuj ua lub luag haujlwm tseem ceeb hauv kev khaws cia cov kev ntsuas ntsuas, uas yog qhov tseem ceeb rau kev nyab xeeb thiab kev ua haujlwm ntawm lub tsheb ciav hlau. Yog tias tsis muaj cov clamps zoo, cov ntsia hlau tuaj yeem hloov mus, ua rau derailments lossis raug nqi taug kev puas tsuaj.
2. Dab tsi yog hom kev tsheb ciav hlau clamps, thiab lawv txawv li cas?
Cov hom kev tsheb ciav hlau feem ntau suav nrog cov hlua khi (xws li Pandrol clips), cov clamps nruj, thiab lub caij nplooj ntoos hlav clips, txhua tus tsim los rau cov xwm txheej tshwj xeeb. Elastic clips siv lub caij nplooj ntoos hlav steel los siv lub siab tsis tu ncua, hloov mus rau me me rail txav los ntawm thermal expansion lossis vibration-zoo tagnrho rau siab -ceev thiab hnyav- cov kab. Rigid clamps, ua los ntawm forged steel, muab kev tuav ruaj khov thiab feem ntau siv nyob rau hauv qis - tsheb ciav hlau lossis lub teeb tsheb ciav hlau qhov twg yuav tsum muaj tsawg kawg nkaus. Caij nplooj ntoos hlav clips, nrog lawv cov coiled tsim, muab kev yooj yim thiab feem ntau siv nrog ntoo sleepers. Qhov sib txawv ntawm lawv cov khoom elasticity, load-cov kabmob muaj peev xwm, thiab cov txheej txheem kev teeb tsa: elastic clips yuav tsum muaj cov cuab yeej tshwj xeeb rau kev teeb tsa, thaum cov clamps nruj yog bolted ncaj qha, thiab lub caij nplooj ntoos hlav clips tuaj yeem ua tau tes- nruj hauv qee kis.
3. Cov ntaub ntawv dab tsi feem ntau yog siv los tsim kev tsheb ciav hlau clamps?
Railway clamps feem ntau yog ua los ntawm qib siab -qib caij nplooj ntoos hlav steel (xws li, 60Si2Mn) vim nws elasticity zoo heev, tensile zog, thiab tiv taus qaug zog. Cov khoom siv no tso cai rau cov clamps rov ua dua nyob rau hauv kev ntxhov siab yam tsis muaj deformation mus tas li, tswj xyuas qhov siab zoo ntawm txoj kev tsheb ciav hlau. Nyob rau hauv ib puag ncig corrosive, clamps tej zaum yuav coated nrog zinc, galvanized, los yog kho nrog anti-cov xim corrosive los tiv thaiv xeb thiab ua rau ntev kev pab cuam lub neej. Rau cov kev siv tshwj xeeb, xws li nyob rau hauv siab - cheeb tsam kub, tshav kub- alloys resistant yog siv los tiv taus huab cua kub. Qee qhov clamps kuj suav nrog cov roj hmab lossis cov khoom yas los ua kom lub suab nrov thiab kev co, ua kom cov neeg caij tsheb xis nyob thiab txo qis hnav ntawm qhov chaw nyob ib sab.
4. Yuav ua li cas railway clamps cuam tshuam nrog lwm yam kev khiav tsheb kauj vab xws li rails thiab sleepers?
Railway clamps tsim ib qho tseem ceeb ntawm kev sib txuas ntawm cov tsheb ciav hlau thiab cov neeg pw tsaug zog: lawv tuav lub hauv paus tsheb ciav hlau kom nruj, tiv thaiv kev hloov mus rau sab nraud, thaum raug thauj mus rau cov neeg pw tsaug zog ntawm bolts lossis cov phaj embedded. Lub clamp tus qauv tsim kom ntseeg tau tias nws siv lub siab sib xws thoob plaws lub hauv paus kev tsheb nqaj hlau, tsis txhob muaj kev ntxhov siab hauv cheeb tsam uas tuaj yeem ua rau txoj kev tsheb ciav hlau puas. Rau cov pob zeb pw tsaug zog, clamps feem ntau haum rau hauv precast recesses, siv lub sleeper rigidity los txhim kho stability. Nrog cov ntoo pw tsaug zog, cov clamps tuaj yeem suav nrog cov phaj loj dua los faib cov siab thiab tiv thaiv ntoo los ntawm kev sib cais. Clamps kuj ua haujlwm nrog cov tshuab ntxhua khaub ncaws thiab cov txiv ntoo los kho qhov nro, ua kom muaj kev ruaj ntseg haum uas haum rau me me kev tsheb ciav hlau tsis muaj loosening. Qhov kev sib cuam tshuam ntawm cov clamps, ntsia, thiab cov neeg pw tsaug zog yog qhov tseem ceeb rau kev tswj xyuas kev ncaj ncees raws li qhov sib txawv.
5. Dab tsi yog cov kauj ruam tseem ceeb rau kev txhim kho railway clamps kom raug?
Kev txhim kho kom zoo ntawm kev tsheb ciav hlau clamps suav nrog ntau cov kauj ruam tseem ceeb. Ua ntej, cov tsheb ciav hlau thiab cov chaw pw tsaug zog yuav tsum tau muab ntxuav kom tshem tawm cov khib nyiab, xeb, lossis av uas tuaj yeem cuam tshuam rau lub clamp tuav. Lub clamp yog tom qab ntawd muab tso rau ntawm lub hauv paus kev tsheb nqaj hlau, ua kom nws nrog cov neeg pw tsaug zog cov ntsiab lus thauj tog rau nkoj (bolts lossis recesses). Rau elastic clips, ib qho cuab yeej tshwj xeeb (xws li clip inserter) yog siv los ua kom cov clip rau hauv qhov chaw, kom nws koom nrog ob qho tib si kev tsheb nqaj hlau thiab pw tsaug zog. Rigid clamps yog ruaj nrog bolts, uas yog nruj rau lub torque uas siv ib tug calibrated ciaj ntswj - dhau - zawm yuav deform lub clamp, thaum nyob rau hauv - zawm yuav cia loosening. Tom qab kev teeb tsa, kev tshuaj xyuas qhov muag pom kev sib raug zoo, thiab kev ntsuas nruj kom ntseeg tau tias lub clamp siv lub siab txaus. Thaum kawg, cov clamps uas nyob ib sab raug kuaj xyuas kom zoo sib xws, tswj kev tsheb ciav hlau tsis sib xws.
