Dab tsi yog cov haujlwm ntawm cov khoom siv hluav taws xob thiab fastening?

Rail fastening yog cov txheej txheem ntawm cov khoom sib txuas uas ruaj ntseg txuas steel hlau rau cov neeg pw tsaug zog (kev sib txuas) thiab cov hauv paus, ua kom muaj kev ruaj ntseg, kev ntsuas kev tsheb ciav hlau zoo, thiab kev nyab xeeb tsheb ciav hlau los ntawm kev tiv thaiv ntsug, sab nraud, thiab longitudinal rog los ntawm kev hla tsheb ciav hlau thaum tseem nqus cov kev vibrations thiab suab nrov, siv cov khoom xws li clips, spikes, tespla pads. Cov hom muaj xws li E-clip, SKL clips, thiab Nabla clips, txhua tus tsim los rau cov kev xav tau tshwj xeeb xws li siab- nrawm lossis hnyav- cov kab, nrog cov ntsiab lus elastic tseem ceeb rau kev nplij siab thiab kev ua neej ntev.

 

 

Dab tsi yog cov haujlwm ntawm cov khoom siv hluav taws xob thiab fastening?

 

Rail fixtures thiab fastenings ruaj ntseg rails rau cov neeg pw tsaug zog, tswj kev taug qab geometry (gauge, alignment) thaum faib cov loads, absorbing vibrations, thiab tso cai rau thermal expansion, kom muaj kev nyab xeeb, ruaj khov kev tsheb ciav hlau los ntawm kev tiv thaiv kev tsheb ciav hlau (kev nkag) thiab muab cushioning rau lub neej ntev dua.

Cov haujlwm tseem ceeb

 

 

• Txhim kho Rails: Muab cov hlua ruaj ntseg rau cov neeg pw tsaug zog (lossis baseplates), nres longitudinal (forward / back) thiab lateral (sideways) txav.

 

• Tswj Kev Ntsuas: Khaws qhov kev ncua deb ntawm cov ntsia hlau, qhov tseem ceeb rau kev sib cuag log thiab tiv thaiv kev tsis ruaj khov.

 

• Load Distribution: Tshaj tawm qhov hnyav ntsug thiab dynamic loads los ntawm cov tsheb ciav hlau uniformly mus rau sleepers thiab ballast.

 

 

• Vibration Damping: Siv cov khoom siv elastic (pads, clips) kom nqus tau qhov cuam tshuam thiab txo cov suab nrov, tiv thaiv cov khoom thiab txhim kho kev caij tsheb.

 

• Thermal Expansion/Contraction: Tso cai rau kev nthuav dav thiab cog lus nrog kev hloov pauv kub yam tsis muaj buckling lossis tawg (piv txwv li, siv cov phaj ntses ntawm cov pob qij txha).

 

• Tiv thaiv Rail Creep: Nres cov ntsia hlau los ntawm maj mam txav mus rau pem hauv ntej hauv qab lub log siv cov khoom xws li cov thauj tog rau nkoj.

 

• Muab Elasticity: Muab cov qib ntawm kev hloov pauv kom tswj tau lub zog muaj zog, txo qis qaug zog thiab hnav.

 

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.

 

 

• Tie daim hlau:Kuj hu ua baseplate lossis ib lub phaj, khi phaj yog steel phaj siv rau kev tsheb ciav hlau ntawm lub flanged T-rail thiab crossties. Lub khi phaj ua kom cov kabmob muaj zog thiab tuav lub tsheb ciav hlau kom kho qhov ntsuas.

 

GNEE RAIL tshwj xeeb hauv kev muab cov ntawv khi xws li cov phaj pw tsaug zog, daim phiaj hauv paus, kev sib txuas ntawm txoj kev tsheb ciav hlau, daim phiaj kev tsheb ciav hlau thiab lwm yam, thiab tau muab cov hlua khi xws li 115RE, 136RE rau North America ua lag luam.

 

• Ntses daim hlau:Splice tuav los yog ob leeg tuav yog hlau tuav uas yog bolted mus rau qhov kawg ntawm ob txoj kab sib txuas los koom ua ke hauv ib txoj kev.

 

 

Nov yog qee cov ntses ntses GNEE tau muab: AREMA tus qauv xws li 115RE, 132RE-136RE series, UIC864 tus qauv UIC60, UIC80 thiab UIC54-series, BS47-1 standard BS75R, BS60A, BS80AS-A, BS90, BS90, 91lb ,ua. 50kg, S49-series ntses daim hlau.

 

• Clips:Clips yog siv los txuas cov ntsia hlau mus rau hauv qab lub hauv paus phaj.

 

GNEE RAIL tshwj xeeb hauv kev muab cov clips xws li E- hom clips nrog diameters xws li 12mm-20mm, tshwj xeeb clips, PR-series elastic clips, SKL-series nro clamps, Deenik clips, Russia clips, Gauge lock clips, Fast clips thiab lwm yam.

Muaj nrog ntau hom kev sib dhos ntawm lub xub pwg nyom. Lwm configurations muaj raws li qhov kev thov.

 

• Ntsia hlau spikes:Lub ntsia hlau ntsia hlau, ntsia hlau ntsia hlau los yog lag bolt yog qhov loj (kwv yees li 6in lossis 152mm ntev, me ntsis hauv qab 1in lossis 25mm hauv txoj kab uas hla) hlau ntsia hlau siv los kho cov hlua khi los yog ncaj nraim rau txoj hlua khi.

 

 

GNEE RAIL muaj peev xwm muab cov rail spikes, railroad spikes, khiav spikes, aub spikes thiab ntsia hlau spikes kom tau raws li AREMA, ASTM, GB, BS, UIC cov qauv.

Rail anchors: Rail anchors, los yog anticreepers, yog lub caij nplooj ntoos hlav steel clips uas txuas mus rau hauv qab ntawm lub tsheb ciav hlau baseplate thiab dais tiv thaiv ob sab ntawm lub sleepers los tiv thaiv longitudinal txav ntawm txoj kev tsheb ciav hlau, los ntawm kev hloov ntawm kub los yog los ntawm kev co.
