Rail Fishplate (Joint Clamp) Core Specifications thiab Kev Sib Txuas Lus
Dab tsi yog cov qauv tseem ceeb ntawm kev tsheb nqaj hlau ntses daim hlau thiab kev hloov kho rail specifications?
Cov phaj ntses tau muab faib ua cov qauv hauv teb chaws thiab txawv teb chaws raws li cov qauv kev tsheb nqaj hlau, cov qauv ua tau raws li cov qauv kev tsheb nqaj hlau thiab hom, thiab tsis tuaj yeem siv hla cov kev qhia tshwj xeeb. Lub teb chaws tus qauv ntses daim hlau yog tsim rau 8-75kg / m lub teb chaws tus qauv rails, 50kg / m rails nrog 50-hom ntses phaj, 60kg / m nrog 60-type, 75kg / m nrog 75-hom, thiab qhov loj haum rau rail puag contour. Cov phaj ntses txawv teb chaws yog tsim rau UIC50/60, American standard 136RE thiab British standard BS80A rails, UIC60 rails nrog European txheem ntses daim hlau, thiab American standard rails nrog American standard tshwj xeeb ntses daim hlau. Lifting rails QU70-120 yog nruab nrog hnyav-lub luag hauj lwm ntses daim hlau nrog tuab tuab thiab ntau bolt qhov rau kev lag luam thiab mining siv, thiab txheem ntses daim hlau yuav siv tau rau zoo tib yam ntsia. Cov phaj ntses kuj tau muab faib ua kev sib koom ua ke thiab bevel sib koom ua ke, 45℃bevel pob qij txha rau cov pob qij txha nthuav dav, thiab cov pob qij txha tiaj tus rau cov khoom siv, xaiv raws li xav tau.
Dab tsi yog cov khoom siv tseem ceeb ntawm cov phaj ntses thiab cov khoom siv kho tshuab tseem ceeb?
Cov ntaub ntawv tseem ceeb ntawm cov phaj ntses yog lub teb chaws tus qauv Q235, Q355 thiab txawv teb chaws tus qauv 900A carbon steel, txhua yam yog tshwj xeeb siab - cov ntaub ntawv muaj zog rau cov pob qij txha uas muaj kev cuam tshuam zoo heev. Q235 ntses daim hlau yog tsim rau lub teeb load lem nrog tensile zog Ntau tshaj los yog sib npaug zos rau 375MPa, zoo plasticity, tsis yooj yim rau tawg thaum lub sij hawm installation thiab economic nqi. Q355 ntses daim hlau yog tsim rau hnyav-lub luag haujlwm thiab siab- kev tsheb ciav hlau ceev nrog lub zog tensile Ntau dua lossis sib npaug li 510MPa, lub zog tawm los Ntau dua lossis sib npaug rau 355MPa, muaj zog deformation tsis kam, thiab tiv taus siab -frequency log. Ntses daim hlau yuav tsum xyuas kom meej qhov tseeb txoj hauj lwm ntawm ntsia liaj qhov rooj qhov nrog pitch deviation Tsawg tshaj los yog sib npaug zos rau ± 0.2 hli los xyuas kom meej du ntsia liaj qhov rooj tsis muaj misalignment jams. Cov ntses phaj saum npoo yog tiaj tus yam tsis muaj burrs thiab kab nrib pleb, thiab cov npoo yog chamfered kom tsis txhob khawb lub tsheb ciav hlau sib koom ua ke thiab txuas ntxiv lub neej kev pab cuam ntawm cov ntsia hlau thiab cov phaj ntses.
Dab tsi yog qhov tseem ceeb bolt configuration thiab xauv qhov yuav tsum tau rau ntses phaj installation?
Kev teeb tsa ntses phaj yog nruab nrog siab- lub zog ntses bolts, tus naj npawb thiab cov ntsiab lus ntawm cov ntsia hlau yog txiav txim siab los ntawm cov qauv ntses phaj, lub teb chaws tus qauv 50- hom ntses phaj yog nruab nrog 4 M24 bolts, thiab 60- hom nrog 6 M27 bolts. Txawv teb chaws tus qauv UIC60 ntses daim hlau yog nruab nrog European standard M27 bolts, American standard ntses daim hlau nrog American standard bolts, lub bolts yog precisely yoog rau cov ntses phaj qhov tsis muaj qhov sib txawv co. Lub xauv torque ntawm ntses bolts yog txiav txim los ntawm qib, 8.8 qib bolts nrog torque 350-400N·m, 10.9 qib nrog 500-550N·m, uniform torque tsis sib txawv, thiab unilateral over-tightening yog txwv tsis pub. Thaum lub sij hawm installation, cov ntses phaj yog nruab nrab kom haum rau txoj kev tsheb ciav hlau sib koom ua ke, qhov sib txawv ntawm qhov sib txawv tsawg dua los yog sib npaug li 0.3 hli, thiab cov rail sib koom ua ke flatness sib txawv tsawg dua los yog sib npaug rau 0.2 hli kom ntseeg tau tias kev tsav tsheb du. Nruab lub caij nplooj ntoos hlav ntxhua khaub ncaws rau kev tiv thaiv kev xoob tom qab xauv, ntxiv cov txiv ntoo xauv rau cov kev ua haujlwm hnyav, tshuaj xyuas lub zog txhua hli thiab rov ua kom rov zoo rau lub sijhawm kom tsis txhob xoob.
Dab tsi yog qhov sib txawv ntawm cov ntses daim hlau rau kev siab - kev tsheb ciav hlau ceev / ib qho kev tsheb ciav hlau / kev lag luam thiab kev tsuas?
High-Speed railway ntses daim hlau yog siab- txoj kev tsheb ciav hlau ceev tshwj xeeb thickened hom nrog thickness Ntau dua los yog sib npaug li 20 hli, ua los ntawm Q355 siab- lub zog steel, haum rau seamless kab auxiliary pob qij txha, yuav tsum tsis tshua muaj siab sib koom flatness nrog sib txawv tsawg dua los yog sib npaug zos rau 0.1mm. Ordinary railway ntses daim hlau yog hom qauv nrog thickness 16-18mm, ua los ntawm Q235, haum rau cov pa sib koom ua ke ntawm ballasted lem, flatness sib txawv tsawg dua los yog sib npaug li 0.3mm yog siv tau nrog cov nqi pheej yig dua. Kev lag luam thiab mining ntses daim hlau yog hnyav-lub luag hauj lwm thickened hom nrog thickness Ntau dua los yog sib npaug rau 22 hli, 2 ntxiv bolt qhov, muab ob npaug rau locking quab yuam, tiv thaiv hnyav load cuam tshuam ntawm hoisting khoom thiab tiv thaiv kev sib koom deformation. High-Speed railway ntses daim hlau xav tau kev kho cov rwb thaiv tsev kom tsis txhob muaj kev cuam tshuam hauv kev sib tw, thiab cov kev tsheb ciav hlau zoo tib yam / kev lag luam thiab cov ntses mining tsis muaj qhov yuav tsum tau muaj rwb thaiv tsev, xaiv raws li xav tau. Kev sib koom ua ke ntawm kev kub ceev railway ntses daim hlau Tsawg dua los yog sib npaug li 0.5 hli, txoj kev tsheb ciav hlau zoo tib yam tsawg dua los yog sib npaug rau 1 hli, kev lag luam thiab mining Tsawg dua los yog sib npaug rau 0.8 hli, qhov sib nrug me me, kev tsav tsheb zoo dua.
Dab tsi yog cov teeb meem tshwm sim thiab kev ntsuas ntsuas ntawm cov phaj ntses hauv kev siv?
Cov teeb meem feem ntau ntawm cov phaj ntses hauv kev siv yog bolt loosening, sib koom ua ke, phaj deformation, tawg tawg thiab rail sib koom offset, txhua tus xav tau kev kho raws sij hawm kom tsis txhob muaj kev phom sij. Bolt loosening yog tshwm sim los ntawm torque attenuation, retighten mus rau tus qauv torque, nruab xauv cov txiv ntseej, thiab tsis tu ncua ua torque nrhiav kom tau hnyav - txoj hauj lwm lem kom tshem tawm loosening. Kev sib koom ua ke ntau dua lossis sib npaug li 1 hli, qhov sib txawv ntawm cov ntses phaj thiab cov tsheb ciav hlau loj heev, cov phaj ntses tshiab yuav tsum tau hloov tam sim ntawd, thiab cov khoom hnav yog txwv tsis pub siv txuas ntxiv kom tsis txhob muaj kev sib koom ua ke. Phaj deformation yog vim overload los yog skew installation, tshem tawm thiab kho qhov deformation, hloov yog tsis tuaj yeem kho, thiab rov kho qhov chaw teeb tsa kom ntseeg tau tias qhov nruab nrab. Kev tawg tawg yog vim cov khoom siv tsis zoo lossis cuam tshuam ntau dhau, tam sim hloov cov phaj ntses nrog siab - cov ntaub ntawv muaj zog, thiab hloov mus rau Q355 hom rau hnyav - cov kab dej num. Rail sib koom ua ke offset yog vim tsis txaus xauv lub zog, xyuas seb cov ntses phaj qauv puas haum, hloov nrog siab - lub zog bolts thiab nce lub xauv lub zog, thiab calibrate txoj hauj lwm rail.
