Qhov FIST Fastening System yog dab tsi
FIST fastening system yog ib qho kev sib txuas ntawm cov tsheb ciav hlau uas tau ua haujlwm tsis tu ncua rau ntau tshaj ob xyoo lawm, feem ntau ntawm cov hnyav- thauj coal networks hauv Australia thiab nyob rau hauv txoj kev tsheb ciav hlau nyob rau sab qab teb Africa. Nws yog Ameslikas tsim nyob rau hauv Sweden thiab tau siv nyob rau hauv ib puag ncig xws li los ntawm tropical coastal corridors rau qhuav inland khiav, uas yog lub ntsiab yog vim li cas nws tseem yog ib tug siv tsim rau elastic fastenings ntawm ntoo thiab pob zeb pw. Nws qhov kev thov rov hais dua yog nyob rau hauv ib qho me me ntawm cov khoom siv muaj zog: ib qho clip uas tswj tau lub zog clamping, ib tus pin insulating uas thauj cov clip thiab cais nws cov hluav taws xob, thiab lub hauv paus ncoo uas faib cov load rau hauv lub txaj pw thiab dampens kev co.
Cheebtsam thiab lawv cov haujlwm
Txhua lub hauv paus yog ib lub luag haujlwm tshwj xeeb, thiab kev hloov pauv ntawm ib qho ntawm lawv hloov tus cwj pwm ntawm tag nrho lub rooj sib txoos.
| Cheebtsam | Muaj nuj nqi | Yam kev tsim kho |
|---|---|---|
| Ntiv clip | Siv thiab tuav lub clamping quab yuam uas tuav txoj kev tsheb ciav hlau tiv thaiv lub ncoo thiab tiv taus ntev, sab nraud thiab txhawb nqa | Tsim lub caij nplooj ntoos hlav steel, tshav kub kho thiab coated rau corrosion kuj |
| Insulated tus pin | Anchors lub clip thiab muab hluav taws xob sib cais ntawm qhov clip thiab lub sleeper fastening los yog khiav qauv | Iav-fiber reinforced polymer nrog lub ntsiab tsav-hauv lossis ntsia hlau- haum |
| Base ncoo | Spreads load tshaj lub sleeper bearing cheeb tsam, damps vibration thiab tiv thaiv lub sleeper nto | Elastomeric los yog composite ncoo, xaiv los ntawm nruj rau lub tsheb thiab pw tsaug zog hom |
Vim hais tias cov clip yog tib lub ntsiab lus uas tau rov ua dua, nws cov khoom zoo thiab kev kho cua sov txiav txim siab lub neej qaug zog ntawm kev sib dhos. Tus pin, los ntawm qhov sib txawv, yog ib qho khoom siv tau zoo: ib zaug rwb thaiv tsev degrades lossis lub taub hau tus pin puas lawm, hluav taws xob sib cais ntawm txoj kev tsheb ciav hlau thiab cov pw tsaug zog ploj lawm thiab lub rooj sib txoos yuav tsum tau rov qab -pinned.
Installation thiab Trackbed xav txog
Kev ua tau zoo ntawm ib qho elastic fastening nyob ntawm qhov xwm txheej ntawm txoj kab hauv qab nws, yog li kev teeb tsa kev qhuab qhia tseem ceeb npaum li cov khoom zoo.
Pw tsaug zog bearing nto yuav tsum yog suab thiab tsis muaj crushing los yog splitting ua ntej tshiab pads thiab clips yog haum, vim hais tias ib tug puas lub rooj zaum yuav tsis txhawb nqa cov ntiv taw.
Lub hauv paus pads yuav tsum tau hloov thaum twg lub rooj zaum pw tsaug zog los yog txoj kev tsheb ciav hlau rov qab los, txhawm rau khaws cov ntaub ntawv tsim kom nruj.
Clips yuav tsum tau nruab nrog lub cuab yeej pom zoo kom cov ntiv taw kom raug ua tiav yam tsis muaj dhau -txhawb cov ceg clip lossis tus pin.
Qhov chaw pw tsaug zog, ntu kev tsheb ciav hlau thiab lub vojvoog nkhaus raug tshuaj xyuas tiv thaiv kev kos duab ua ntej xaj; lub rooj sib txoos tau teev tseg raws li qhov system, tsis yog raws li tus kheej qhov chaw.
Cov khoom siv hlau muaj kev tiv thaiv los ntawm kub-dip galvanizing lossis zinc{1}}flake txheej, nrog cov txheej tuab tau txheeb xyuas qhov ua tiav.
Kev Ua Tau Zoo thiab Kev Tshawb Fawb
Rail fastening systems siv nyob rau hauv mainline khiav yog ib txwm tsim nyog tiv thaiv cov European txheem series rau fastening kev ua tau zoo, nrog rau cov kev xeem tau kos los ntawm tus khub kev xeem tus qauv series.
| Kev xav tau | Dab tsi yog qhov tseeb |
|---|---|
| Longitudinal txwv | Resistance rau rail txav nyob rau hauv rov qab longitudinal load, kom qhov sib txawv qhib thiab rail kev nyuaj siab nyob rau hauv lub tsim txwv |
| Rov qab load peev | Kev qaug zog tus cwj pwm ntawm clip thiab tus pin nyob rau hauv cyclic ntsug load, soj ntsuam los ntawm tus qauv rov ua dua -load test method rau fastening systems |
| Hluav taws xob tsis kam | Rwb thaiv tsev ntawm kev tsheb ciav hlau thiab cov neeg pw tsaug zog tau txheeb xyuas nyob rau hauv ob qho tib si qhuav thiab ntub dej siv cov qauv kev ntsuas hluav taws xob tiv thaiv |
| Corrosion kuj | Txheej kev ua tau zoo qhia tau los ntawm nruab nrab ntsev tsuag raug thiab los ntawm adhesion xyuas ntawm cov khoom tiav |
| Sib dhos repeatability | ntiv taw load ntsuas ntawm tus qauv ntawm cov khoom sib dhos kom paub meej tias cov txheej txheem teeb tsa muab lub zog clamping tshwj xeeb hauv kev khiav |
Kev ntsuas kev tsim nyog yog ua tiav ntawm kev sib dhos ua tiav ntau dua li ntawm cov khoom sib cais, vim tias kev sib cuam tshuam ntawm clip, tus pin thiab lub ncoo txiav txim siab qhov tshwm sim. Thaum tus neeg siv khoom qhia txog tus qauv txheej txheem hloov ntawm European series, tib qhov kev sim matrix yog siv thiab qhov kev lees paub qhov tseem ceeb raug coj los ntawm qhov project specification.
Kev Kho, Kev Tshuaj Xyuas thiab Kev Pabcuam Lub Neej
Hauv kev pabcuam, ib qho elastic fastening raug tshuaj xyuas raws li ib feem ntawm txoj kev taug kev ib txwm muaj. Cov kev tshawb pom ntau tshaj plaws yog ib qho deformed los yog corroded clip, tawg los yog xoob insulated tus pin, thiab lub hauv paus ncoo uas tau coj mus tas li. Txhua qhov muaj qhov tshwm sim meej: qhov tsis muaj zog clip txo qhov kev ncua ntev, tus pin ua tsis tau zoo tshem tawm cov hluav taws xob rwb thaiv tsev thiab tuaj yeem tso cai rau cov clip nkag mus, thiab cov ntaub qhwv compressed hloov cov khoom xa tawm mus rau hauv lub txaj pw.
Yog li kev tshuaj xyuas yuav tsum tau sau cov xwm txheej clip, tus pin kev ncaj ncees thiab cov ntaub qhwv tuab ntawm cov chaw sawv cev, thiab kev hloov pauv yuav tsum ua raws li cov phiaj xwm tau teem tseg es tsis yog ib qho reactive. Qhov twg tus khiav nqa hnyav qag loads nyob rau hauv ib tug corrosive ib puag ncig, cov tswv yim txoj kev yog mus re-pin thiab hloov ntaub nyob rau hauv lub ncua ncua sij hawm thaum txuas dua tshiab clips tsuas yog thaum ntsuas los yog pom kev xav tau nws. Tuav lub rooj sib txoos ua ib qho system, nrog cov khoom seem, cov pins thiab cov ntaub qhwv ntawm tib qhov kev qhia tshwj xeeb khaws cia ua ke, ua kom tus cwj pwm fastening zoo ib yam nyob rau hauv qhov ntev ntawm txoj kev khiav thiab zam qhov kev hloov hauv lub zos nruj uas tshwm sim thaum cov khoom tsis sib haum yog sib xyaw rau hauv tib seem.
Cov lus nug nquag
Q: Dab tsi yog qhov tseem ceeb ntawm FIST fastening system?
Lub rooj sib txoos muaj lub nrig ntiv tes uas siv lub zog clamping, ib tus pin insulated uas thauj cov clip thiab muab hluav taws xob cais tawm, thiab lub hauv paus ncoo uas kis tau mus rau hauv lub txaj pw thiab dampens kev co.
Q: Vim li cas tus pin insulated tseem ceeb?
Nws tswj cov hluav taws xob sib cais ntawm txoj kev tsheb ciav hlau thiab cov neeg pw tsaug zog, uas yuav tsum tau ua rau kev khiav haujlwm hauv Circuit Court. Ib tus pin tawg, xoob lossis degraded yog qhov kev pabcuam tsis raug txawm tias qhov clip nws tus kheej tseem tsis zoo.
Q: Cov qauv twg siv rau lub kaw lus fastening zoo li no?
Mainline systems feem ntau tsim nyog tiv thaiv cov European fastening kev ua tau zoo tus qauv series, siv tus khub xeem txoj kev series rau rov load, hluav taws xob tsis kam thiab lwm yam khoom, ntxiv rau ntsev tsuag corrosion xeem ntawm coated qhov chaw.
Q: Yuav ua li cas ntiv taw load tswj thaum lub sij hawm installation?
Los ntawm kev siv cov cuab yeej pom zoo rau hom clip, ua raws li cov txheej txheem kev teeb tsa, thiab txheeb xyuas cov ntiv taw thauj khoom ntawm tus qauv ntawm cov khoom sib dhos es tsis txhob cia siab rau qhov muag pom ib leeg.
Q: Thaum twg yuav tsum tau hloov cov ntaub qhwv thiab pins?
Lub hauv paus pads yog ib txwm rov ua dua tshiab thaum lub rooj zaum pw tsaug zog lossis lub tsheb ciav hlau hloov. Pins yuav tsum tau hloov thaum twg rwb thaiv tsev puas lawm los yog lub taub hau qhia kev nyuaj siab, feem ntau nyob rau ib ncua sij hawm nyob rau hauv hnyav-haul, corrosive txoj kev.
Q: Cov khoom puas tuaj yeem sib xyaw los ntawm cov tshuab fastening sib txawv?
Tsis yog. Clip, tus pin thiab ncoo yog tsim los ua ib qho system, thiab cov khoom sib xyaw ua ke hloov cov clamping quab yuam thiab ncoo txhav, ua kom muaj kev sib txawv hauv cheeb tsam hauv kev khiav uas nyuaj los ntawm kev soj ntsuam pom.
