Railway clips yog cov elastic fastening ntsiab uas tuav lub tsheb ciav hlau ko taw tiv thaiv lub hauv paus los yog pw tsaug zog. Ib qho clip ua haujlwm los ntawm elastic deformation: nws yog nias rau hauv lub xub pwg nyom los yog clamped hla txoj kev tsheb ciav hlau ko taw, thiab nws lub caij nplooj ntoos hlav ua rau lub zog clamping, ntiv taw load, uas tiv thaiv kev tsheb nqaj hlau thiab kev txav mus rau sab nraud thaum tso cai rau kev tswj ntsug deflection. Clips yog tsim los ntawm siab - carbon caij nplooj ntoos hlav steel, feem ntau 60Si2MnA los yog 55SiCr nyob rau hauv Suav xyaum, quenched thiab tempered mus rau ib tug hardness ntau yam ntawm 42-50 HRC, thiab yog tsim los rau ntau lab lub sij hawm load.
Qhov twg Railway Clips siv
Ballasted mainlines: clips thiab elastic fastenings tuav lub tsheb ciav hlau ntawm cov pob zeb lossis ntoo pw tsaug zog thiab yog cov txheej txheem daws teeb meem ntawm cov kab niaj hnub.
Ballastless siab - khiav ceev: ntawm slab khiav, clips yog thawj elastic caij; lub kaw lus yuav tsum tswj cov ntiv taw ntawm qhov siab heev excitation.
Turnouts thiab keyboards: hla cov vaj huam sib luag yuav tsum muaj kev ruaj ntseg clamping siab vim tias cov khoom hnyav hnyav thiab yuav tsum tuav txoj hlua hloov kom raug.
Cov choj thiab cov tunnels: elastic fastenings nqus cov kev vibrations uas yuav kis tau mus rau hauv cov qauv, thiab tso cai rau txoj kev tsheb ciav hlau txav mus rau hauv kev txwv ntawm qhov chaw txuas ntxiv.
Nroog metro thiab tram systems: clips ua ke nrog resilient pads txo hauv av- ua suab nrov thiab kev co hauv qhov av thiab ua - thaj chaw.
Hnyav-haul corridors: high clamping force clip systems tuav txoj kev tsheb ciav hlau tiv thaiv siab longitudinal thiab lateral rog nyob rau hauv loj qag loads.
Yuav ua li cas Clips ua hauj lwm nrog lub Fastening System
Kev ua tiav elastic fastening muaj xws li clip, lub xub pwg nyom los yog ntxig cam khwb cia rau hauv lub sleeper, ib tug rail ncoo ntawm txoj kev tsheb ciav hlau thiab pw tsaug zog, thiab feem ntau yog insulators ntawm clip thiab rail. Thaum cov clip tau tsav mus tsev, nws deflects elastically thiab tsim cov ntiv taw load uas nias lub tsheb ciav hlau mus rau hauv ncoo. Kev teeb tsa raug raug: dhau- tsav tsheb ua rau muaj kev ntxhov siab dhau ntawm tus nqi tsim, thiab hauv qab - tsav tsheb tawm hauv qhov clip xoob kom lub tsheb ciav hlau tuaj yeem tso rau hauv kev tsheb. Clips yog tsim los rau ib tug txhais taw load range, feem ntau 9-12 kN rau ib tug qauv elastic clip thiab siab dua rau hnyav-haul systems, thiab cov ntiv taw load yuav tsum tau soj ntsuam nrog ib tug ntsuas ntsuas thaum lub sij hawm installation.
Clip Hom los ntawm Geometry
Clips feem ntau piav qhia los ntawm lawv cov duab geometry: e-puab clips (cov e-clip tsev neeg), omega-puab clips nrog lub hauv paus koov, thiab ob-tig lossis ntau- tig hlau clips. Lub geometry txiav txim siab qhov deflection ntau, ntiv taw load thiab qaug zog tus cwj pwm. Kev xaiv yog qhov system- tshwj xeeb: txhua lub kaw lus fastening yog tsim nyob ib ncig ntawm ib daim ntawv clip, lub xub pwg nyom thiab insulator teeb, yog li kev sib xyaw cov tsev neeg hauv ib lub cev tsis pom zoo.
Qhov twg Clips tsis yog thawj qhov kev xaiv
Ntawm cov ntoo- cov kab pw tsaug zog uas tsis tshua muaj kev ceev thiab lub teeb tsheb, cov tsheb ciav hlau (dub spikes) tseem muaj ntau vim tias lawv pheej yig thiab ceev rau nruab. Spikes yog nruj: lawv tsis muab cov elastic clamping thiab vibration damping uas clips muab, thiab lawv tsis muaj peev xwm tuav ib tug txhais ntiv taw load, yog li niaj hnub mainline xyaum yog txav cov kab no rau elastic fastenings qhov twg tsheb xav tau nws. Rail pob qij txha kuj feem ntau siv fishplate bolts es tsis yog clips; clips fasten txoj kev tsheb ciav hlau rau nws cov kev txhawb nqa, lawv tsis koom nrog kev sib tw.
Cov ntsiab lus xaiv rau cov neeg yuav khoom
Tshawb xyuas cov ntaub ntawv tsheb ciav hlau ua ntej: qhov clip thiab lub xub pwg nyom yuav tsum sib npaug ntawm txoj kab tsheb ciav hlau qhov dav ntawm qhov tseeb profile (piv txwv li 60 kg / m, UIC54, 115RE). Tom qab ntawd paub meej tias lub fastening system hom thiab cov pw tsaug zog los yog slab nws yuav raug ntsia rau, vim lub xub pwg geometry txawv ntawm lub tshuab. Txheeb xyuas qhov clip steel qib, kev kho cua sov thiab txheej txheej: clips feem ntau muab nrog kev tiv thaiv corrosion tsim nyog rau qhov chaw ib puag ncig, thiab ntsev tsuag tshuaj tiv thaiv yuav tsum tau teev rau cov kab ntug hiav txwv. Thaum kawg, thov cov ntaub ntawv ntsuas kev qaug zog: clips yuav tsum muaj sia nyob ntawm tus lej ntawm kev thauj mus los yam tsis tau poob ntau dua li qhov tso cai ntiv taw, raws li cov qauv siv fastening system.
FAQ
Dab tsi yog qhov txawv ntawm txoj kev tsheb ciav hlau clip thiab lub tsheb ciav hlau?
Ib qho clip yog lub caij nplooj ntoos hlav elastic uas tuav lub tsheb ciav hlau nrog lub zog clamping tswj thiab absorbs kev co; ib tug spike yog ib tug nruj fastener tsav mus rau hauv lub pw tsaug zog. Clips yog reusable thiab muab zoo tuav nyob rau hauv siab - ceev thiab hnyav - tsheb thauj mus los.
Cov ntaub ntawv dab tsi yog railway clips ua los ntawm?
High- carbon caij nplooj ntoos hlav steel xws li 60Si2MnA lossis 55SiCr, quenched thiab tempered txog 42-50 HRC, nrog kev tiv thaiv corrosion. Stainless hlau los yog coated clips muaj nyob rau hauv ib puag ncig nruj.
ntiv taw load yog dab tsi thiab vim li cas nws tseem ceeb?
ntiv taw load yog ntsug clamping quab yuam lub clip siv rau cov tsheb ciav hlau ko taw. Yog tias nws qis dhau, lub tsheb thauj neeg nqa thiab cov twj tso kua mis hauv qab tsheb; yog tias siab dhau lub ncoo thiab pw tsaug zog yog overloaded. Txhua qhov fastening system txhais cov ntiv taw load ntau yam uas installation yuav tsum ua tiav.
Ntev npaum li cas clips yuav tsum tau hloov?
Nrog rau kev txhim kho kom raug, clips kav lub neej ntawm lub fastening system, feem ntau 15-20 xyoo. Kev hloov pauv yog tsav los ntawm qaug zog, corrosion lossis poob ntawm ntiv taw load, uas yog vim li cas kev soj ntsuam ib ntus nrog lub ntsuas ntiv taw yog ib feem ntawm kev saib xyuas.
Tib qhov clip tuaj yeem siv rau ntawm qhov sib txawv rail profiles?
Tsis yog. Cov clip, insulator thiab lub xub pwg nyom sib phim rau txoj kev tsheb ciav hlau qhov ntev ntawm ib qho profile. Ib daim clip tsim rau UIC60 yuav tsis tuav 50 kg / m rail kom raug.
Cov clips siv nyob rau hauv siab - cov kab nrawm txawv ntawm cov khoom siv li cas?
Tib cov tsev neeg clip tau siv, tab sis siab - ceev ballastless tshuab xav kom nruj dua kev ua haujlwm siab, kev ua haujlwm qaug zog ntau dua thiab tswj cov ntiv taw nruj dua vim tias qhov vibration zaus thiab acceleration yog siab dua ntawm cov kab lus.
