Dab tsi yog qhov zoo tagnrho rail sib koom?
Dec 31, 2025
Rail sib koomplays ib qho kev sib koom ua ke (kev sib txuas ua haujlwm) hauv kev tsheb ciav hlau. Kev sib koom ua ke ntawm txoj kev tsheb ciav hlau zoo tuaj yeem txo qhov cuam tshuam ntawm lub log thaum dhau los ntawm kev sib koom ua ke ntawm cov hlau rail thiab ua rau kom ruaj khov thiab txuas ntxiv ntawm cov tsheb ciav hlau hla. Raws li ib qho tseem ceeb ntawm txoj kev tsheb ciav hlau, txoj kev tsheb ciav hlau sib koom ua ke tau dav siv ob qho tib si hauv kev tsheb ciav hlau thiab hnyav tsheb ciav hlau los lav kev nyab xeeb ntawm kev tsheb ciav hlau.
- Rail sib koom ua ke rau lub teeb rail: 8kg, 9kg, 12kg, 15kg, 18kg, 22kg, 24kg thiab 30kg
- Rail sib koom ua ke rau hnyav rail: 38kg, 43kg, 50kg thiab 60kg
- Rail sib koom ua ke rau crane rail: QU70, QU80, QU100 thiab QU120

Dab tsi yog qhov zoo tagnrho rail sib koom?
Txoj kev tsheb ciav hlau zoo tshaj plaws ua haujlwm zoo li kev tsheb ciav hlau tsis tu ncua: nws muab kev sib npaug ntawm lub zog, nruj, thiab kev sib haum xeeb (ob leeg kab rov tav thiab ntsug) raws li txoj kev tsheb ciav hlau nws tus kheej, thaum tso cai rau thermal expansion, absorbing shocks, resisting longitudinal rog (ceep), thiab ua kom yooj yim hloov, tag nrho ntawm tus nqi tsawg. Nyob rau hauv qhov tseeb, welded (nruam welded rail) pob qij txha los ze tshaj, tab sis bolted pob qij txha yuav tsum sib npaug cov kev xav tau kev sib tw, feem ntau yog siv fishplates, bolts, thiab ua tib zoo tsim qhov khoob.
Cov yam ntxwv tseem ceeb ntawm Txoj Kev Zoo Tshaj Plaws Rail Joint:
- Continuity & Alignment: Tuav cov tsheb ciav hlau xaus zoo kawg nkaus ua raws kab rov tav thiab ntsug kom tiv thaiv lub log bounce.
- Strength & Stiffness: Sib phim lub zog thiab nruj ntawm txoj kev tsheb ciav hlau kom tsis txhob ua qhov tsis muaj zog tshaj plaws.
- Thermal Movement: Muab qhov chaw rau cov hlua kom nthuav dav thiab cog lus nrog kev hloov kub.
- Elasticity: Absorbs vibrations thiab shocks los ntawm cov tsheb ciav hlau hla.
- Longitudinal Resistance: Resistant rail creep (longitudinal txav) tshwm sim los ntawm braking thiab acceleration.
- Maintainability: Tso cai rau kev hloov kho yooj yim raws li qhov chaw hnav thiab tso cai hloov tsheb ciav hlau yooj yim.
- Tus nqi-Yuav ua tau zoo: Kev lag luam rau nruab thiab tswj nws lub neej.
Cov phaj ntses ua haujlwm li cas?
Daim phiaj ntses tsis yog zaum ntawd xwb -lawv ua haujlwm tseem ceeb. Nov yog qhov lawv ua kom koj txoj kev tsheb ciav hlau humming.
- Load Sharing: Ntses daim hlau faib lub tsheb ciav hlau lub nra ntawm cov pob qij txha. Qhov no txwv tsis pub rails ntawm twisting los yog tawg. Tons ntawm steel yob dhau los, tsis tau cov lem tuav ruaj.
- Thaum tshav kub kub Movement Control: Rails stretch nyob rau hauv warmth thiab shrink nyob rau hauv txias. Ntses daim hlau tso cai me me, tswj kev hloov pauv. Qhov no tiv thaiv warping los yog splits hauv kab.
- Txo txo qis: Lawv nqus cov pob los ntawm kev hla tsheb ciav hlau. Qhov ntawd txo qis racket. Tsis tas li ntawd, nws thaiv cov kab nrib pleb uas yuav ua mob rau lub sijhawm.
Qhov zoo ntawm GNEE Rail Joints:
- Nrog tshaj 80% kev ua lag luam sib koom hauv Tuam Tshoj Railway kev lag luam raws li kev sib koom ua lag luam.
- Peb tuaj yeem muab ib nrab- cov khoom tiav tsis muaj qhov lossis cov khoom tiav nrog qhov.
