1. Yuav ua li cas rau Fastening System yuav tsum xa
Lub tsheb ciav hlau fastening system muaj plaub txoj haujlwm: nws clamps txoj kev tsheb ciav hlau mus rau cov neeg pw tsaug zog lossis slab tiv thaiv ntsug, lateral thiab longitudinal rog; nws muab elasticity rau damp log loads thiab tiv thaiv lub txaj khiav; nws insulates lub tsheb ciav hlau hluav taws xob rau kev taw qhia thiab stray-tam sim no tswj; thiab nws tiv thaiv corrosion dhau lub neej kev pab cuam ntsuas hauv kaum xyoo. Txhua hom kab xav tau tag nrho plaub lub luag haujlwm, tab sis qhov hnyav sib txawv, thiab kev ua kom zoo rau ib daim ntawv thov yuav ua tsis tau rau lwm qhov. Lub luag haujlwm engineering yog xaiv cov kev sib txuas ntawm cov clip, lub hauv paus phaj, ncoo, ntsuas qhov thaiv thiab kho uas phim lub qag load, ceev, ib puag ncig thiab kev saib xyuas lub tswv yim ntawm cov kab tshwj xeeb.
2. High-Speed Railways
Kev ua haujlwm siab - nrawm nrawm ua rau qhov kev xav tau nruj tshaj plaws ntawm kev rov qab elasticity, kev vibration tsis kam thiab ntev - lub sij hawm txhua yam kev ruaj ntseg, vim tias qhov poob me me ntawm clamping quab yuam los yog lub ncoo hnav hloov pauv txoj kab geometry uas lub tsheb ciav hlau ntsib ntawm 350 km / h. Cov kab ke feem ntau yog Hom III elastic clips thiab WJ-8 thiab WJ-9 fastening tsev neeg, uas muab clamping quab yuam nyob rau hauv chav kawm 20 kN, qaug zog lub neej ntawm ob peb lab cycles thiab meej gauge tuav. Hauv qab -rail ncoo tau teev tseg rau qhov tsis tshua muaj zog nruj kom txo qis kev co xa mus rau cov slab, thiab lub fastening yuav tsum tuav gauge nyob rau hauv nruj tolerances - feem ntau ± 1 hli - nyob rau hauv ob qho tib si thermal thiab braking rog. Cov qauv xws li TB/T 3065 thiab EN 13481-2 Chav Kawm D txhais cov qauv kev lees paub rau cov tshuab no, suav nrog kev rub tawm, ntsuas kev qaug zog thiab ntsuas qhov ntev.
3. Heavy-Haul thiab Freight Lines
Heavy-txoj kev taug kev, xws li cov thee thiab ore thauj cov kab, ua haujlwm nrog lub nra hnyav ntawm 25-30 t thiab muaj zog cuam tshuam rau ntawm lub taub hau tsheb ciav hlau. Yog li ntawd, lub fastening yuav tsum nqa ntau dua ntsug load, tiv thaiv abrasion los ntawm lateral rail txav, thiab muab siab longitudinal tsis kam kom lub tsheb ciav hlau tsis nkag rau hauv braking thiab traction. These lines typically use elastic clip systems reinforced with high-density gauge blocks and high-strength bolts, with clamping force at the upper end of the range and rail pads of higher stiffness to spread the load. Cov qauv tsis ua hauj lwm los tsim tawm tsam yog clip qaug zog, ntsuas qhov thaiv qhov hnyav thiab qhov ua kom xoob xoob, yog li kev soj ntsuam lub sijhawm luv dua thiab cov khoom raug xaiv kom hloov tau yooj yim hauv cov qhov rais muaj.
4. Nroog Transit: Metro thiab Light Rail
Metro thiab lub teeb rail systems hnyav hluav taws xob rwb thaiv tsev, kev co thiab suab nrov txo thiab corrosion kuj hnyav dua li lwm daim ntawv thov. Tsheb ciav hlau pib thiab nres nquag nyob rau hauv qhov chaw uas tsis muaj tam sim no los ntawm DC traction tawm tsam lub zog ntawm lub txaj, yog li lub fastening yuav tsum muab siab rwb thaiv tsev tiv thaiv ntawm txoj kev tsheb ciav hlau thiab cov pw tsaug zog los yog slab. Rubber pad khaubncaws sab nraud povtseg thiab ntab slab los yog resilient fastening designs yog dav siv los ua kom tau raws li kev co txwv ntawm EN 16272 thiab cov suab nrov hauv zos cov cai, thiab kev tiv thaiv corrosion yog teev rau cov av noo, waterlogged thiab de-icing ib puag ncig. Lub fastening kuj yuav tsum zam nruj nkhaus thiab nquag braking, uas txhais tau hais tias lub ntsuas qhov thaiv thiab clip ntiv taw pom kev hnav siab thiab yuav tsum tau hloov pauv yam tsis muaj kev cuam tshuam cov tsheb ciav hlau.
5. Ballastless Track
Nyob rau hauv ballastless khiav txoj kev tsheb ciav hlau yog mounted ncaj qha mus rau ib tug pob zeb slab, yog li ntawd lub fastening system yog tib qhov chaw ntawm gauge, theem thiab kev kho. Nws yuav tsum tau lees paub qhov ntsuas qhov ceev ceev, muab kev hloov kho ntsug los ntawm kev teeb tsa cov phiaj los yog shims los kho cov slab casting tolerances, thiab thauj tog rau nkoj cov tsheb ciav hlau tawm tsam longitudinal rog yam tsis muaj kev cia siab rau ballast kuj. Ua ntej- lub tes tsho embedded nyob rau hauv lub slab tau txais cov ntsia hlau spikes los yog bolts, thiab lub dowel tiv thaiv cov xov rau rov ua dua - zawm. Vim hais tias tsis muaj tamping, lub fastening lub elastic Cheebtsam - ncoo, clip thiab insulating qhov chaw - nqa tag nrho lub luag hauj lwm rau damping, uas yog vim li cas ballastless systems integrate lub ncoo thiab puag phaj raws li ib tug matched los ua ke es tsis txhob xoob qhov chaw.
6. Ib qho kev xaiv rau pawg neeg yuav khoom
Cov txheej txheem xaiv cov tswv yim pib nrog cov kab ua haujlwm: siab tshaj plaws ceev, qag load, nkhaus radii thiab txhua xyoo tonnage. Nws txuas ntxiv nrog rau ib puag ncig - ntug dej hiav txwv ntsev, qhov av, de- cov tshuaj icing, alpine kub - uas txiav txim siab qhov corrosion specification, thiab nrog rau cov hluav taws xob, uas txiav txim siab qhov yuav tsum tau rwb thaiv tsev. Thaum kawg, kev saib xyuas lub neej tseem ceeb: kev ceev ceev uas tsis tuaj yeem muab kev pabcuam hauv cov khoom luv luv, lossis nws cov khoom tsis raug cai, ua rau lub neej nce ntxiv - mus txog tus nqi txawm hais tias nws pib nqi. Cov khoom xa tuaj yog cov npe luv ntawm cov tsev neeg fastening uas ua tau raws li EN 13481-2 Chav Kawm D lossis qhov sib npaug hauv lub tebchaws, nrog cov ntawv pov thawj kev xeem rau clamping quab yuam, qaug zog, longitudinal tsis kam thiab rwb thaiv tsev, thiab cov ntaub ntawv pad thiab clip sib xyaw ua ke rau cov kev tsheb ciav hlau tshwj xeeb. Cov kev paub dhau los ntawm cov kab zoo sib xws yog qhov kawg lim, thiab qhov chaw sim ntawm ntu luv tau pom zoo ua ntej kev teeb tsa dav hlau.
