Track Fastening System: Tag Nrho Cov Kev Sib Tw Sib Tw thiab Kev Ua Haujlwm Kev Ua Haujlwm Hloov Cov Cai
Dab tsi yog qhov tseem ceeb muaj pes tsawg leeg thiab kev txhawb nqa logic ntawm kev khiav ceev ceev?
Txoj kev khiav ceev yuav siv txoj kev tsheb ciav hlau los ua lub hauv paus thiab tsim kom muaj kev txhawb nqa ua tiav nrog cov hlua khi, cov phaj siab, siab - lub zog bolts, spikes thiab hauv qab - tsheb ciav hlau pads. Cov ntsiab lus txhawb nqa logic yog "cov qauv tsheb ciav hlau txiav txim siab cov khoom siv tshwj xeeb", lub teb chaws tus qauv 50kg / m rail sib raug rau 50-hom fastening accessories, thiab UIC60 rail sib haum mus rau European standard SKL fastening Cheebtsam. Lub kaw lus fastening yog muab faib ua elastic fastening thiab nruj fastening, hom elastic muaj xws li elastic clip tsis qhov chaw, thiab cov hom nruj tsom rau kev ruaj ntseg thiab kev txwv. Thaum lub sij hawm kev txhawb nqa, nws yog ib qho tsim nyog los xyuas kom meej tias tag nrho cov khoom siv tau raug kho kom haum thiab haum rau txoj kev tsheb ciav hlau thiab kev pw tsaug zog tsis muaj qhov khoob kom tsis txhob xauv qhov tsis ua haujlwm los ntawm cov khoom siv tsis sib haum. Lub kaw lus fastening kuj yuav tsum tau hloov mus rau lub ballast txaj hom, lub ballastless khiav siv integrated fastening, thiab ballasted khiav siv split fastening.
Dab tsi yog qhov sib txawv ntawm kev sib tw khiav ceev rau kev siab - kev tsheb ciav hlau ceev / ib qho kev tsheb ciav hlau / kev lag luam thiab kev tsheb ciav hlau?
Lub siab - kev tsheb ciav hlau ceev ceev yog ib qho kev sib xyaw ua ke ntawm elastic clips, insulating pads thiab 10.9 qib bolts, tsom rau buffering thiab tiv thaiv - loosening, adapting rau cov kev cai nruj ntawm ballastless lem. Txoj kev tsheb ciav hlau zoo tib yam yog qhov sib cais tsis sib xws, siv 8.8 qib bolts + ncaj phaj siab daim hlau, tsom rau qhov yooj yim locking, hloov mus rau cov yam ntxwv deformation ntawm ballasted lem nrog tus nqi pheej yig dua. Cov kev lag luam thiab cov mining khiav ceev ceev yog ib qho hnyav - hom haujlwm, nruab nrog forged siab daim hlau + xauv txiv ntseej, nrog lub zog xauv lub zog kom tiv thaiv qhov cuam tshuam ntawm cov khoom siv hoisting. Qhov sib nrug ntawm qhov siab - ceev railway fastening system yog 600mm, zoo tib yam railway 800mm, industrial thiab mining 500mm, thiab qhov sib nrug yog kho raws li cov load ceev. High- Kev nrawm nrawm nrawm yuav tsum tau kho cov rwb thaiv tsev, thiab tsis muaj qhov yuav tsum tau muaj rwb thaiv tsev rau kev tsheb ciav hlau zoo tib yam / kev lag luam thiab kev tsuas, uas tuaj yeem xaiv raws li qhov xav tau.
Dab tsi yog cov ntsiab lus tseem ceeb thiab kev siv txoj hauv kev los tiv thaiv -loosing tsim ntawm lub kaw lus fastening?
Lub hauv paus ntawm fastening system tiv thaiv - loosening yog los tiv thaiv bolt loosening thiab elastic clip tsis ua hauj lwm, xyuas kom tsis muaj transverse offset ntawm txoj kev tsheb ciav hlau, uas yog tus yuam sij rau taug qab kev nyab xeeb. Cov ntsiab lus tseem ceeb ntawm kev tiv thaiv -loosing tsim yog "nrawm torque + structural anti-loosing + khoom anti- attenuation", lub bolt locking torque yog txiav txim siab raws li qib kom tsis txhob muaj txaus los yog ntau dhau torque. Cov qauv kev tiv thaiv- loosening siv lub caij nplooj ntoos hlav ntxhua khaub ncaws thiab xauv cov txiv ntseej, ua ke nrog elastic pre- zawm ntawm elastic clips los ua ob npaug los tiv thaiv-loosing nyhuv. Cov khoom siv los tiv thaiv- loosening siv siab- lub zog alloy steel accessories nrog qaug zog thiab deformation tsis kam kom tsis txhob muaj kev ua haujlwm attenuation thaum lub sij hawm ntev - siv. Tom qab kev teeb tsa, nws yog ib qho tsim nyog yuav tsum tsis tu ncua tshuaj xyuas tus nqi torque, rov kho dua ib hlis ib zaug, thiab ua raws sijhawm los daws cov kev phom sij zais kom ntseeg tau tias muaj kev tiv thaiv kav ntev -loosing nyhuv.
Dab tsi yog cov ntsiab lus tshwj xeeb sib piv cov cai ntawm lub teb chaws / txawv teb chaws tus qauv fastening systems?
Lub teb chaws tus qauv fastening system yog yoog raws GB tus qauv, cov qauv siv yog 50/60/75 hom, cov bolts yog M24 / M27 lub teb chaws tus qauv specifications, thiab elastic clips yog lub teb chaws tus qauv hom Ⅰ / Ⅱ / Ⅲ. Cov txheej txheem txawv teb chaws fastening yog yoog rau UIC / Asmeskas / Askiv tus qauv rails, UIC60 rails tau nruab nrog SKL15 / SKL30 European tus qauv fastening Cheebtsam, thiab American standard rails yog nruab nrog AREMA txheem bolts. Cov xov ntawm lub teb chaws tus qauv fastening accessories yog lub teb chaws tus qauv metric, thiab txawv teb chaws tus qauv yog nti / European tus qauv xov, cov xov specifications tsis tuaj yeem siv crossly thiab yuav tsum tau sib phim. Lub teb chaws tus txheej txheem fastening system siv TB railway tus qauv, thiab txawv teb chaws tus qauv siv UIC / AREMA thoob ntiaj teb tus qauv, thiab kev lees paub zoo yog ua raws li tus qauv sib xws. Thaum siv thoob plaws cov qauv, cov khoom siv adapter customized yuav tsum tau ua kom ntseeg tau tias ob- txoj kev hloov ntawm qhov loj thiab xov kom tsis txhob muaj teeb meem.
Dab tsi yog qhov tseem ceeb ntawm kev tsim kho thiab cov qauv kev lees paub rau kev txhim kho fastening system?
Rau kev txhim kho cov txheej txheem fastening, nws yog ib qho tsim nyog yuav tsum tau ntxuav lub sleeper installation nto ua ntej, thiab tso rau hauv qab -rail ncoo tom qab tsis muaj impurities thiab roj stains kom lub ncoo yog tiaj tus tsis muaj ntug warping. Tom qab ntawd txo qis txoj kev tsheb ciav hlau kom ntsuas qhov ntsuas, nruab qhov elastic clip / lub phaj siab thiab lub tes tsho ntawm lub ntsia liaj qhov rooj, ua ntej- nruj thiab tom qab ntawd ua qhov kawg nruj nrog lub torque ciaj ntswj raws li tus qauv torque, thiab skew installation yog nruj me ntsis txwv. Cov qauv kev lees paub tseem ceeb yog: lub phaj siab haum rau txoj kev tsheb ciav hlau tsis muaj qhov khoob, qhov elastic clip compression yog 2-3mm, lub ntsia liaj qhov rooj tsis muaj xov slipping, thiab lub tsheb ciav hlau ntsuas qhov sib txawv tsawg dua los yog sib npaug rau ± 2mm. Tom qab fastening, txoj kev tsheb ciav hlau tsis muaj transverse / ntsug offset, cov khoom siv tsis muaj deformation thiab kev puas tsuaj, thiab tsis muaj kev cuam tshuam ntawm lub txaj ballast thiab cov khoom fastening. Tom qab kev lees paub, yuav tsum muaj kev ntsuas kev thauj khoom, thiab nws tuaj yeem raug muab tso rau hauv kev siv yog tias tsis muaj lub suab nrov txawv txav thaum lub sijhawm ua haujlwm ntawm lub teeb, thiab kev ntsuas kev cuam tshuam kuj tseem xav tau rau kev ua haujlwm hnyav.
