Dab tsi yog qhov thauj tog rau nkoj ntev hauv txoj kev tsheb ciav hlau?
Nyob rau hauv txoj kev tsheb ciav hlau, "lub thauj tog rau nkoj ntev" yog hais txog qhov ntev ntawm txoj kev tsheb ciav hlau uas yuav tsum tau kho kom tiv thaiv lub zog (thermal expansion / contraction los yog vibration) ua ntej ib qho kev sib koom ua ke lossis ib qho chaw thauj tog rau nkoj, feem ntau hla tsawg kawg yog ob txoj kab ntev (piv txwv li, 39-78 ft lossis ntau dua) qhov twg txhua qhov peb khi yuav tsum tau ruaj khov rau txoj kev taug qab). Nws yog thaj chaw uas muaj kev tiv thaiv kev tsheb ciav hlau, ua kom muaj kev ruaj ntseg, tshwj xeeb tshaj yog nyob ze cov txuas hniav lossis qhov chaw ntev welded rails ntsib cov seem sib koom ua ke, tso cai rau tus so ntawm txoj kev mus rau "ua pa".
Qhov tseem ceeb ntawm Anchor Length:
- Lub hom phiaj: Txhawm rau nres longitudinal (raws li txoj kev) txav mus rau hauv ntu ntawm txoj kev uas yuav hloov pauv vim qhov kub hloov pauv lossis tsheb ciav hlau vibrations.
- Qhov chaw: Feem ntau siv los ze rau qhib- cov choj txuas, ntawm qhov kawg ntawm Long Welded Rails (LWRs) ua ntej hloov cov pob qij txha txuas ntxiv (SEJs), lossis qhov kev tsim qauv yuav tsum tau kho.
- Kev Ua Haujlwm: Feem ntau suav nrog kev siv cov thauj tog rau nkoj (caij nplooj ntoos hlav steel clips) rau lub hauv paus kev tsheb nqaj hlau thiab nias tawm tsam tus neeg pw tsaug zog (khi).
- Qhov ntev ntawm qhov sib txawv: Qhov ntev ntev yog nyob ntawm hom kev tsheb ciav hlau, qhov kub thiab txias hloov pauv, khiav gradient, thiab cov kev xav tau tshwj xeeb ntawm txoj kev tsheb ciav hlau, sib txawv ntawm kaum mus rau ntau pua meters.
Lub luag haujlwm ntawm lub tsheb thauj mus los yog dab tsi?
Lub tsheb ciav hlau thauj tog rau nkoj lub luag haujlwm tseem ceeb yog txhawm rau tiv thaiv txoj kev tsheb ciav hlau los ntawm kev txav mus ntev (xav mus rau pem hauv ntej lossis rov qab) raws cov crossties, ib qho tshwm sim hu ua "ceeping," tshwm sim los ntawm kev hloov pauv kub thiab tsheb ciav hlau. Los ntawm clamping rau ntawm lub hauv paus kev tsheb nqaj hlau thiab nias tiv thaiv txoj hlua khi, lub caij nplooj ntoos hlav no- cov khoom siv hlau xa cov quab yuam, tswj kev tsheb ciav hlau sib dhos, thiab tiv thaiv kev hnav ntawm cov hlua khi, ua kom muaj kev ruaj ntseg thiab kev nyab xeeb, tshwj xeeb tshaj yog nyob rau hauv nkhaus, gradients, thiab siab - kab ceev.

rail anchors siv nyob qhov twg?
- Lub tsheb ciav hlau thauj tog rau nkoj yog siv nyob rau hauv qee qhov chaw ntawm txoj kev tsheb ciav hlau. Ua ib qho piv txwv 39-ko taw, nws yuav tsum tau ntsuas ntawm 8 lub tsheb ciav hlau thauj tog rau nkoj, raws li pom hauv daim duab hauv qab no. Nrog rau qhov nce ntawm txoj kab nqes, nws xav tau ntau npaum li cas ntawm cov tsheb ciav hlau anchors.
- Lub rail anchoring ntaus ntawv yog siv nyob rau hauv txoj kev nyob ze ntawm lub qhib lawj choj, ib feem peb ntawm cov pob qij txha yuav tsum tau kho nyob rau hauv lub kawg ntawm tus choj rau tsawg kawg yog 2 rail ntev.
- Raws li txoj kev tsheb ciav hlau nrog lub thauj tog rau nkoj, txhua qhov peb lub strip yuav tsum yog lub thawv thauj khoom, nrog tsawg kawg yog ob txoj kev tsheb ciav hlau ntev los ntawm kev sib tshuam mus rau txhua qhov kev qhia.
- Rail anchors tuaj yeem siv rau kev tsheb ciav hlau. Nws yog qhov pab tau los kho cov teeb meem geometric thaum siv anchors hauv turnouts.
GNEE RAILmuab cov tsheb ciav hlau thauj tog rau nkoj uas haum rau ntau yam kev tsheb ciav hlau qhov ntev xws li 85LB, 90LB, 115RE, 132RE UIC54, UIC60, 50kg, thiab lwm yam. Cov khoom tsim los ntawm cov qauv siab thiab tau dhau daim ntawv pov thawj ISO9001, ua pov thawj rau kev sib tw hauv cov xwm txheej sib txawv.
