Dab tsi yog txoj kev tsheb ciav hlau?

 

Ib txoj kev tsheb ciav hlau yog qhov ntev steel profile tsau rau ntawm cov neeg pw tsaug zog (kev sib raug zoo) uas ua rau qhov chaw khiav ntawm lub tsheb ciav hlau log, coj cov tsheb raws li txoj kev uas tau teev tseg ua ntej thaum hloov lub log tsheb mus rau cov qauv kev sib tw thiab kev sib tw. Tsis zoo li cov qauv hlau dav dav, txoj kev tsheb ciav hlau yog qhov tseeb -engineered, hnav- cov khoom siv hlau uas tsis muaj zog tsim los tiv thaiv kev rov ua haujlwm siab dua, cuam tshuam cov quab yuam, thiab kev sib cuag nrog kev qaug zog.

 

 

Hauv kev ua tiav kev tsheb ciav hlau, txoj kev tsheb ciav hlau ua haujlwm ua ke nrog cov tsheb ciav hlau nrawm, cov tsheb ciav hlau, cov paib hauv qab, cov pw tsaug zog, ballast lossis slab, thiab cov pob qij txha lossis cov welds los tswj kev ntsuas, kev sib tw, thiab kev caij tsheb.

 

Yuav Ua Li Cas Taug Kev Rail Mounted thiab Kho rau Txoj Kev?

 

Cov tsheb ciav hlau tsis raug ntsia ib leeg; lawv yog ib feem ntawm lub kaw lus fastening uas ua kom ntsuas kev ruaj ntseg, kev co damping, thiab thermal expansion tswj. Cov yam ntxwv muaj xws li:

 

• Elastic rail clips los yog ntsia liaj qhov rooj fastenings

 

• Rail pads rau kev co thiab hluav taws xob rwb thaiv tsev

 

• Base daim hlau los yog daim hlau ib leeg rau kev xa khoom thauj

 

• Fishplates los yog aluminothermic welds rau cov pob qij txha

 

 

Cov kev tsheb ciav hlau niaj hnub no nce siv txuas txuas txuas txuas rail (CWR) txhawm rau tshem tawm kev sib koom ua ke thiab txhim kho kev caij tsheb. Rau crane lem thiab industrial systems, bolted pob qij txha thiab adjustable fastening assemblies yog tseem lug siv los tso cai kho kom haum.

 

Dab tsi yog the Lub Hom Phiaj Ntawm Txoj Kev Taug Kev Siv Hauv Railways?

 

Cov kev tsheb ciav hlau feem ntau tau muab cais los ntawm qhov hnyav ib 'meter', profile geometry, thiab daim ntawv thov scenario, tsis yog los ntawm ib tus qauv thoob ntiaj teb. Tej pawg muaj xws li lub teeb rail, hnyav rail, crane rail, thiab grooved rail.

 

 

Rail Hom	Yam Nyhav Ntau Yam	Cov ntawv thov tseem ceeb	Cov Standards
Lub teeb rail	8-30 kg / m	Trams, mines, factories, ib ntus lem	GB 11264, JIS 15-30kg, ASCE
Hnyav rail	38–{1}} kg/m	Mainline railways, metro, hnyav thauj	EN 13674 (60E1), UIC 60, AREMA 136RE, GB 60kg
Crane rail	50-120 kg / m (dav puag)	Port cranes, steel mills, yards	DIN 536, YB / T 5055 (QU rails)
Grooved rail	~ 50-60 kg / m	Txoj kev tramways kos rau hauv txoj kev	EN grooved rail series

 

Piv txwv li, UIC 60 (60.21 kg / m) thiab EN 60E1 rails tswj cov neeg caij tsheb niaj hnub thiab cov kab loj thauj khoom, thaumwb 22kglos yog JIS 22kg lub teeb rails yog ib yam rau kev lag luam thiab lub teeb hla kev. GNEE RAIL muab cov ntaub ntawv no raws li ntau tus qauv thiab tuaj yeem ua raws li cov qauv kev tsheb nqaj hlau nrog cov txheej txheem fastening thiab cov ntaub qhwv los xyuas kom muaj kev ncaj ncees thiab kev co tswj.

 

Raws li tus kws tshaj lij rail fastener tsum,GNEE RAILtuaj yeem muab cov qauv steel sib txawv xws li GB, Asmeskas, BS, UIC, DIN, JIS, Australian thiab South Africa uas siv rau hauv txoj kev tsheb ciav hlau, cranes thiab thee mining.
