Cov qauv tsim ntawm seamless turnout

Kev sib koom ua ke tsis muaj kev sib koom ua ke yog qhov tseem ceeb ntawm kev sib koom ua ke tsis sib xws. Nws dais qhov kev ua haujlwm ntawm qhov kub thiab txias quab yuam ntawm kev sib koom ua ke raws li txoj kev tsheb ciav hlau ntev. Lub tsheb ciav hlau nyob rau hauv lub turnout tsis tsuas yog dais loj thermal quab yuam, tab sis kuj muaj ntau yam kev ntxhov siab nyob rau hauv ob qho tib si kawg ntawm lub puab rail kab. Qhov tsis sib npaug ntawm thermal quab yuam lub xeev no yog qhov kev hloov ntawm kev ntxhov siab thiab deformation ntawm txoj kev tsheb ciav hlau nyob rau hauv seamless turnout, thiab yog cov teeb meem tseem ceeb uas yuav tsum tau daws nyob rau hauv kev tsim, tso, txij nkawm thiab txij nkawm ntawm seamless turnout.

Cov yam ntxwv ntawm seamless turnout
Kev tsim qauv ntawm kev sib koom ua haujlwm-hluav taws xob yog qhov txuas tseem ceeb heev hauv kev tsim qauv ntawm seamless turnout. Ntawm qhov tod tes, lub teeb liab yuav tsum xyuas kom meej qhov kev hloov pauv hloov pauv thiab ntsuas lub zog, ntawm qhov tod tes, nws yuav tsum yooj yim hloov mus rau qhov kev nthuav dav dawb thiab kev cog lus ntawm kev hloov tsheb ciav hlau thiab taw tes rail nyob rau hauv kev sib koom ua ke, thiab tswj qhov qub. ua hauj lwm kab ntawm kev hloov tsheb ciav hlau thiab taw tes rail tom qab hloov dua siab tshiab;
Ntawm qhov tod tes, kev ua haujlwm pej xeem muab qhov chaw ua haujlwm zoo thiab kev teeb tsa platform rau pej xeem kev ua haujlwm, ntawm qhov tod tes, nws tseem yuav tsum tau koom tes nrog cov pej xeem ua haujlwm hauv kev tsim qauv kom kov yeej qhov tsis txaus ntawm kev hloov pauv. kev tsheb ciav hlau thiab qhov chaw nruab nrab ntawm txoj kev hloov dua siab tshiab, ua kom luv luv ntawm kev nthuav dav ntawm kev hloov tsheb ciav hlau thiab qhov chaw tsheb ciav hlau hauv qhov kev sib koom ua ke kom deb li deb tau, thiab zam kev hloov pauv tsis ua haujlwm dhau qhov kev tso cai ntawm pej xeem kev ua haujlwm, feem ntau hu ua " jamming"

Basic cai rau seamless turnout qauv
Ntxiv nrog rau kev coj tus kheej txhua yam ntawm sab hnub tuaj-sab hnub poob loads ntawm locomotives thiab tsheb zoo li qhov zoo tib yam turnout, seamless turnout kuj bears loj kub quab yuam. Yog li ntawd, lub turnout qauv npaj rau vuam thiab nteg rau hauv seamless turnout yuav tsum muaj tej yam yooj yim tej yam kev mob thiab ua tau raws li qhov tsim nyog cov txheej txheem.
(1) Ob qhov kawg ntawm qhov kev sib tw yuav tsum yog welded thiab tuaj yeem welded ua ke nrog txoj kev tsheb ciav hlau ntev ntawm kev sib koom ua ke siv cov cuab yeej siv vuam zoo. Thaum tsim nyog, ob qhov kawg ntawm kev xa tawm kuj tseem tuaj yeem txuas nrog txoj kev tsheb ciav hlau ntev los ntawm "txias" lossis kev sib txuas.
(2) Lub turnout rail fastener yuav tsum tau txais lub zog elastic fastener los ua kom lub zog thawb ntawm lub fastener ntau dua li qhov ntev ntawm txoj kev khiav ntawm lub txaj hauv qhov chaw tig tawm. Thaum siv lub gusset phaj fastener, lub anti-creep locking ntawm lub puab rail ntawm turnout yuav tsum tau ntxiv dag zog. Nws yog qhov zoo dua los siv lub caij nplooj ntoos hlav bar fastener. Lub fastener ntsia liaj qhov rooj yuav tsum tau nruj raws li lub torque teev.
(3) Kev hloov tsheb ciav hlau thiab pob taws kawg ntawm qhov nruab nrab ntawm txoj kev tsheb ciav hlau yuav tsum tau teeb tsa nrog cov khoom siv sib kis xws li spacers lossis limiters kom paub qhov ntev ntawm lub zog sib kis ntawm ob txoj kab. Kev sib txuas bolts ntawm cov khoom siv hluav taws xob sib txuas yuav tsum yog lub zog muaj zog bolts kom nce lawv cov kev sib txhuam thiab kev sib txhuam ntawm cov bolts, thiab yuav tsum tau nruj nrog lub zog torque.
(4) Lub turnout sleepers ntawm seamless turnout yuav tsum muaj txaus transverse dabtsi yog khoov rigidity. Reinforced qhob turnout sleepers nrog hom II los yog hom III elastic fasteners tuaj yeem ua lub luag haujlwm ntawm cov pob zeb turnout sleepers nyob rau hauv nce rail longitudinal quab yuam.
(5) Lub txaj khiav hauv qhov chaw tawm mus yuav tsum puv thiab tuab. Kev saib xyuas tshwj xeeb yuav tsum tau them rau kev sau thiab tamping lub ballast nyob rau hauv lub turnout sleeper box, thiab lub xub pwg ballast yuav tsum widened raws li qhov yuav tsum tau ntawm kev sib koom ua ke khiav.
(6) Cov khoom siv xws li kev hloov pauv, ntsuas qhov ntsuas thiab ntsuas qhov sib khi yuav tsum hloov mus rau qhov loj ntawm kev hloov pauv ntawm kev hloov tsheb ciav hlau thiab chaw nruab nrab, thiab yuav tsum tsis txhob ua rau kev hloov pauv tsis ua haujlwm vim qhov nthuav dav ntawm kev hloov tsheb ciav hlau.
(7) Kev tsim ntawm txhua qhov chaw thiab cov khoom siv nyob rau hauv lub turnout, nrog rau kev teeb tsa ntawm lub qhov ntsia hlau, yuav tsum coj mus rau hauv tus account qhov cuam tshuam ntawm txoj kev tsheb ciav hlau nthuav dav thiab kev cog lus kom tsis txhob muaj teeb meem xws li lub qhov rooj qhov dislocation thiab qhov chaw sib tsoo.

Kev sib kis ntawm qhov kub thiab txias quab yuam ntawm seamless turnout
Tom qab tshem tawm lub cev cais tawm ntawm seamless turnout (tag nrho cov ncaj sab strands yog welded) los ntawm seamless khiav, txoj kev hloov ntawm qhov kub thiab txias quab yuam nyob rau hauv lub turnout yog qhia nyob rau hauv daim duab. Nws tuaj yeem pom tias qhov kub thiab txias ntawm qhov ntev thiab luv qhov nruab nrab ntawm qhov kev sib tw tom qab qhov kev sib tw yog hloov mus rau lub tis rail thiab kev taw qhia kev tsheb ciav hlau (piv txwv li cov kev taw qhia kev tsheb ciav hlau txuas ncaj qha mus rau txoj kab ncaj nraim) los ntawm cov kab qag pob taws, thiab mus rau cov tsheb ciav hlau los ntawm hloov pob luj taws qauv; Thaum lub sij hawm nthuav dav thiab kev cog lus ntawm cov lus qhia kev tsheb ciav hlau, nws tseem ua rau cov neeg taug kev pw tsaug zog txav mus ntev, thiab xa ib feem ntawm qhov kub thiab txias quab yuam mus rau cov khoom thauj khoom. Nws tuaj yeem pom tau tias kev tsim cov qauv kev hloov pauv hauv kev hloov pauv yog ib qho ntawm cov thev naus laus zis tseem ceeb los xyuas kom meej tias qhov kev ntxhov siab thiab deformation ntawm kev sib koom tes tsis sib haum yog tsim nyog thiab kom paub txog kev sib koom ua ke tsis muaj nyob hauv Kua ntu.

Force kis muaj nuj nqi ntawm fastener
Lub fastener yog ib qho tseem ceeb hauv kev sib koom ua ke. Hauv kev sib koom ua ke zoo tib yam tsis muaj kev sib tw, nws qhov kev ua haujlwm ntev ntev yuav tsum muaj ntau dua li qhov ntev ntawm kev ua haujlwm ntawm lub txaj. Tus txheeb ze hloov chaw ntawm txoj kev tsheb ciav hlau thiab cov pw tsaug zog yog tswj xyuas kom ntseeg tau tias cov kab siab tshaj plaws. Nyob rau hauv seamless turnout, qhov kev tiv thaiv ntawm lub fastener kuj yuav tsum tau kom loj npaum li sai tau los xyuas kom meej tias qhov kub thiab txias quab yuam ntawm lub puab rail yog pauv mus rau turnout sleeper thiab ces mus rau lub Tshuag rail. Lub longitudinal tsis kam ntawm lub fastener ntawm ob lub puab ntsia hlau yog sib npaug rau qhov sib npaug ntawm lub zog ntev ntawm lub txaj khiav ntawm lub txaj pw ntawm lub txaj pw thiab qhov ntev ntev ntawm ob txoj hlua. Yog li ntawd, sab hauv kev taw qhia ntawm lub puab rail fastener yog opposite rau lub longitudinal tsis kam kev taw qhia ntawm lub Tshuag rail, thiab qhov sib thooj kub quab yuam gradient kuj opposite.
Force hloov ua haujlwm ntawm turnout sleeper
Tom qab bearing lub longitudinal quab yuam kis los ntawm lub puab rail fastener, lub turnout pw tsaug zog yuav txav longitudinally, offset thiab txawm khoov transversely, thiab ces lub Tshuag rail yuav tsiv mus nyob rau hauv lub fastener kuj, thiaj li mus paub qhov kev hloov ntawm kub quab yuam los ntawm lub puab. rail mus rau Tshuag rail. Qhov ntau ntom ntawm ballast taug kev txaj yog, qhov loj ntawm qhov chaw hla ntawm qhov chaw pw tsaug zog yog, thiab ntau dua qhov ntev ntawm lub txaj khiav yog. Yog li ntawd, qhov me me ntawm qhov ntev ntawm cov khoom siv rail fastener yog, qhov me dua qhov kev ntxhov siab thiab deformation ntawm cov khoom tsheb ciav hlau.
