Ib txoj kev tsheb ciav hlau feem ntau yog tsim los ntawmrails, railroad ties (sleepers), fasteners, railway switch, ballast, subgrade.Lub Cheebtsam ntawm kev tsheb ciav hlau khiav ua si sib txawv hauv kev muab kev txhawb nqa rau tsheb ciav hlau. Cov qauv khiav yog tsim rau dov Tshuag kom yob raws li kev nyab xeeb thiab du. Ob tus neeg caij tsheb thiab cov kab tsheb thauj khoom tau txais txiaj ntsig los ntawm qhov yooj yim khiav khiav ceev tsheb thauj mus los.
hlau rail
Qhov tseem ceeb ntawm txoj kev tsheb ciav hlau yogtxoj hlua. Feem ntau cov tsheb ciav hlau niaj hnub no muaj qhov profile uas zoo li tus I-beam vertically symmetric tab sis kab rov tav asymmetric. Txhawm rau ua kom tau raws li qhov xav tau ntawm kev xa tawm, txuas txuas loj, thiab cov kab tsis sib luag thiab lwm cov qauv, tsis yog - axisymmetric rails raug tsim thiab.
Txoj kev tsheb ciav hlau yog tsim los ntawm cov hlau uas tuaj yeem raug kev nyuaj siab heev los ntawm cov tsheb ciav hlau. Txhawm rau ua kom lub tsheb ciav hlau zoo dua tuaj yeem tiv thaiv lub zog los ntawm txhua sab, kom ntseeg tau tias qhov tsim nyog muaj zog, cov ntsia hlau yuav tsum tau tsim nrog qhov siab txaus. Nws lub taub hau thiab ko taw yuav tsum muaj thaj tsam txaus thiab qhov siab, lub vev xaib thiab ko taw yuav tsum tsis txhob nyias dhau. Rails raug cais raws li kev tsheb ciav hlau loj thiab kev tsheb ciav hlau hnyav. Feem ntau, cov tsheb ciav hlau hnyav dua txhawb nqa ntau dua qag thiab cov tsheb ciav hlau siab dua.
Railway pw tsaug zog
Ib tug railway sleeper kuj hu ua railroad khi los yog crosstie. Nws yog ib qho yooj yim overlooked feem ntawm railway lem. Cov neeg pw tsaug zog tsis tsuas yog txhawb nqa txoj kev tsheb ciav hlau tab sis kuj tseem tuav txoj haujlwm ntawm txoj kev tsheb ciav hlau. Tsis tas li ntawd, nws pab kom xa cov siab loj los ntawm kev tsheb ciav hlau mus rau lub trackbed. Nws yuav tsum muaj qee qhov kev hloov pauv thiab elasticity. Nws tsis tuaj yeem nyuaj lossis mos dhau. Thaum lub tsheb ciav hlau hla dhau, nws tuaj yeem raug deformed kom cushion lub siab. Tab sis, nws yuav tsum tau rov qab los ntau li ntau tau. Thaum ntxov, txoj kev tsheb ciav hlau sib txuas yog ua los ntawm ntoo thaum prestressed pob zeb yog ntau pom tam sim no. Qee zaum cov yas sib xyaw ua ke kuj tau siv.
rail fasteners
Fasteners yog siv los kho cov tsheb ciav hlau rau cov tsheb ciav hlau. Nws kuj yog ib qho tseem ceeb heev ntawm txoj kev tsheb ciav hlau. Feem ntau pom cov fasteners muaj xws li spikes, screws, rail thauj tog rau nkoj, khi daim hlau, rooj zaum, thiab lwm yam. Ntau hom fasteners tau siv ntau xyoo. Lwm cov ntaub ntawv taug qab xws li rail clip, rail clamp, rail pad, rail pob qij txha kuj muaj rau railway fastening systems.
Lub luag haujlwm tseem ceeb ntawm rail fastening system yog raws li hauv qab no.
- Zoo lav qhov txhim khu kev qha kev sib txuas ntawm kev tsheb ciav hlau thiab tsheb ciav hlau, tsheb ciav hlau thiab pw tsaug zog. Khaws qhov txuas ntxiv thiab kev ncaj ncees ntawm txoj kev tsheb ciav hlau mus rau qhov zoo tshaj plaws.
- Tiv thaiv txoj kab rov tav thiab ntsug ntawm cov hlau rail txheeb ze rau tus neeg pw tsaug zog, xyuas kom meej qhov ntsuas qhov qub.
- Ua kom tag nrho cov buffering thiab kev vibration txo kev ua tau zoo nyob rau hauv lub zog ntawm lub locomotive thiab lub tsheb kom ncua lub tsub zuj zuj ntawm residual deformation ntawm kab.
Rail clip
Rail elastic clipyog siv los fasten cov ntsia hlau rau hauv qab phaj phaj ua ke nrog cov pob zeb pw tsaug zog. Feem ntau rail clips yog ua los ntawm forged caij nplooj ntoos hlav steel uas yog tsim los ntawm kub forging txheej txheem. Vim hais tias ntawm cov niaj hnub microstructure ntawm forged clips, nws yog suav hais tias yuav zoo dua lwm yam hlau txoj kev.
GNEE RAIL muaj ntau yam kev tsheb ciav hlau clips nrog qhov zoo tshaj plaws, cov tsheb ciav hlau clips no yog tsim los nrog kev ua haujlwm siab thiab ua los ntawm cov qib siab zoo caij nplooj ntoos hlav steel. GNEE tau yog lub hauv paus loj tshaj plaws thiab kev sib tw ntau tshaj plaws ntawm kev tsheb ciav hlau nyob hauv Suav teb tom qab ntau tshaj 18 xyoo 'rail clip tsim kev paub, thiab muaj kev tsim nyog rau kev sib tw hauv teb chaws loj thiab nruab nrab cov phiaj xwm kev tsheb nqaj hlau. Dab tsi ntxiv, peb txoj kev tsheb ciav hlau tuaj yeem hloov kho raws li cov neeg siv khoom xav tau.

Rail clamp
Lub ntsiab daim ntawv thov ntawmrail clampsyog rau cranes. Rau txoj kev teeb tsa, lawv tuaj yeem muab faib ua bolted rail clamps thiab welded rail clamps.
Rail ncoo
A rail ncoo, tseem hu ua rail roj hmab phaj, feem ntau yog siv ntawm khi daim hlau thiab cov neeg pw tsaug zog lossis nruab nrab ntawm cov ntsia hlau thiab khi phaj. Lub rail ncoo yog ua los ntawm elastic polyurethane lev thiab feem ntau yog siv rau cov pob zeb pw tsaug zog. Lub rail ncoo tuaj yeem tiv thaiv lub pob zeb pw tsaug zog los ntawm kev puas tsuaj thiab kev cuam tshuam, thiab nws tuaj yeem txo qhov kev vibration ntawm lub tsheb ciav hlau hla. Nws ntseeg tau tias txoj kev tsheb ciav hlau ua haujlwm hauv ob txoj hauv kev: txo qis kev poob siab thiab faib cov khoom thauj. Lub thickness ntawm peb rail pads yog li ntawm 5mm mus rau 25mm, tab sis feem ntau qhov siab yuav tsum tsis txhob yuav siab heev nyob rau hauv cov ntaub ntawv ntawm kev txav mus los ntawm cov ntsia hlau.

rail sib koom
Rail pob qij txha, feem ntau hu ua fishplate, feem ntau hu ua qhov sib koom ua ke, yog cov khoom sib koom ua ke kawg - mus rau - kawg. Raws li kev siv sib txawv, cov pob qij txha rail tuaj yeem muab faib ua bolted rail pob qij txha, cuam tshuam cov pob qij txha thiab cov pob qij txha insulated.
Railroad hloov
Railway hloov tseem hu ua turnout. Raws li nws lub npe qhia, nws yog ib qho khoom siv rau dov cov khoom lag luam kom tig los ntawm ib qho mus rau lwm qhov. Nws yog feem ntau nteg nyob rau hauv ntau ntawm cov chaw nres tsheb thiab marshalling chaw nres tsheb. Nrog turnouts, koj tuaj yeem muab kev ua si tag nrho rau lub peev xwm dhau ntawm kab. Txawm hais tias nws yog ib qho - txoj kev tsheb ciav hlau, nteg cov neeg tawm mus thiab tsim ib ntu ntawm txoj kab nkhaus uas ntev tshaj qhov ntev ntawm lub tsheb ciav hlau los faib lub tsheb ciav hlau. Turnouts ua lub luag haujlwm tseem ceeb hauv cov kab tsheb ciav hlau.
GNEE RAILMuaj ntau hom kev tsheb ciav hlau fasteners kom tau raws li cov neeg siv khoom xav tau, xws li Elastic Rail Clip thiab Clamp, Rail Screw Spike, Yas Dowel, High Tensile Track Bolt nrog txiv ntseej, Rail Base (Tie) Phaj, Rail Fish Phaj, Rail Lub xub pwg (Ntxig), Ntses Bolt, Railroad Rubber thiab EVA Pad, thiab lwm yam.
