Track Plate Limiting thiab Locking Technology thiab Contour Adaptation
Dab tsi yog qhov tseem ceeb ntawm cov qauv kev faib tawm ntawm cov phaj siab thiab cov kev qhia tshwj xeeb uas siv tau?
Cov phaj siab khiav tau muab faib ua 50- hom, 60- hom, 75- hom, UIC60- hom thiab QU hnyav- hom haujlwm raws li lub teb chaws / txawv teb chaws tus qauv / hom tsheb ciav hlau. Cov qauv sib raug raws li cov qauv kev tsheb ciav hlau thiab cov lus qhia tshwj xeeb ib los ntawm ib qho, tsis muaj qauv universal. 50- hom phaj siab haum rau 50kg / m lub teb chaws tus qauv kev tsheb nqaj hlau, qhov dav dav haum rau txoj kev tsheb ciav hlau qhov tuab, paub txog kev txwv tsis pub kaw thiab ua tau raws li qhov xav tau ntawm cov kab tsheb ciav hlau zoo tib yam . 60- hom phaj siab yog 1 txoj kev tsheb ciav hlau loj } Cov kab hauv lub cev, haum rau 60kg / m lub teb chaws tus qauv kev tsheb nqaj hlau, lub qhov yog nrog los tiv thaiv - cov kab hauv qab, qhov txwv thiab tiv thaiv - sab nraud cov nyhuv yog qhov zoo dua, thiab kev tsav tsheb ruaj khov dua . 75- hom phaj siab yog haum rau 75kg / m siab - ceev railway txoj kab loj rail, nrog thickened 5 lateral quab yuam tsim, nrog rau kev sib tw quab yuam ntau dua 5%. siab- tsav tsheb ceev thiab tshem tawm cov tsheb ciav hlau khiav tawm. UIC60-hom phaj siab yog tsim rau European txheem UIC60 rail, lub qhov thiab qhov chaw yog tsim raws li European qauv, ncaj qha docking hla ciam teb railway tej yaam num. QU heavy-duty siab phaj yog tsim rau QU70-120 lifting rail, tshwj xeeb rau kev lag luam thiab mining siv, los tiv thaiv dov thiab tsis-deformable.
Dab tsi yog cov khoom siv tseem ceeb thiab cov qauv kev ua haujlwm zoo ntawm cov phaj siab khiav?
Cov ntaub ntawv tseem ceeb ntawm cov phaj siab yog lub teb chaws tus qauv Q355B qis alloy steel, Q235B carbon steel, txawv teb chaws tus qauv S275JR European tus qauv hlau, thiab hnyav- lub luag haujlwm siab phaj ntxiv nrog hnav- cov txheej txheem tawv tawv. Cov khoom siv zog yoog mus rau kab load, nrog deformation thiab cuam tshuam tsis kam. Q355B siab phaj yog tus qauv tseem ceeb rau kev siab - kev tsheb ciav hlau ceev thiab hnyav thauj khoom, nrog lub zog tensile Ntau dua los yog sib npaug rau 510MPa, yield zog ntau dua los yog sib npaug rau 355MPa, tsis muaj tawg nyob rau hauv txias dabtsi yog khoov, tsis muaj yas deformation tom qab xauv, thiab zoo heev qaug zog kuj. Q235B siab phaj yog cov qauv kev tsheb ciav hlau zoo tib yam, nrog lub zog tensile Ntau dua lossis sib npaug ntawm 375MPa, zoo plasticity, ua haujlwm yooj yim, siab installation haum, pheej yig tus nqi, ua tau raws li cov kev txwv yooj yim. Qhov saum npoo ntawm hnyav- lub luag haujlwm siab phaj yog carburized thiab hnav-resistant, nrog hardness Ntau dua los yog sib npaug rau 55HRC, qhov kev tiv thaiv -rolling hnav tsis kam yog nce los ntawm 3 zaug, yoog rau siab - zaus load cuam tshuam hauv kev lag luam thiab mining thiab ncua kev pab cuam lub neej. Tag nrho cov phaj siab yuav tsum ua tau raws li qhov sib txawv ntawm qhov sib txawv tsawg dua los yog sib npaug ntawm 0.2mm thiab qhov loj me me kam rau ua Tsawg dua los yog sib npaug rau ± 0.1mm los xyuas kom meej seamless haum nrog lub hauv paus rail thiab kev ntxhov siab.
Dab tsi yog qhov tseem ceeb ntawm cov qauv thiab kev ua haujlwm sib txawv ntawm siab -ceev / ib txwm / kev lag luam mining siab daim hlau?
High -Speed railway siab phaj txais yuavelastic txwv integrated qauv, lub qhov yog nrog arc chamfer, haum rau txoj kev tsheb ciav hlau tsis muaj ntug khawb, ua tau - hauv elastic gasket, nrog ob qho tib si txwv thiab micro- buffering zog, yoog raws qhov kev txwv nruj ntawm kev siab - ceev railway ballastless khiav. Ordinary railway siab phaj yogtxhav ncaj phaj qauvtsis muaj elastic Cheebtsam, lub qhov yog txoj cai - lub kaum sab xis tsim, yooj yim ua, tsom rau cov ntshiab lateral txwv, adapting me ntsis deformation ntawm zoo tib yam railway ballasted khiav nrog tus nqi qis. Kev lag luam thiab mining siab phaj yog hnyav-lub luag hauj lwm thickened hom, thickness ntau tshaj los yog sib npaug zos rau 20mm, lub qhov yog widened thiab tob, tus naj npawb ntawm cov ntsia liaj qhov rooj qhov yog nce mus rau 4, lub locking quab yuam yog ob npaug, tiv thaiv lub dov tej yam ntawm industrial thiab mining hnyav khoom thiab tiv thaiv lub siab phaj deformation. High- ceev railway siab phaj yog txuam nrog 10.9 qib insulating bolts nrog insulating txheej kom tsis txhob conduction cuam tshuam nrog khiav Circuit Court. Ordinary railway / kev lag luam mining siab phaj yog txuam nrog 8.8 / 12.9 qib zoo tib yam bolts yam tsis muaj rwb thaiv tsev. Qhov txwv qhov tseeb ntawm qhov siab -ceev railway siab phaj Tsawg dua los yog sib npaug rau 0.1 hli, txoj kev tsheb ciav hlau zoo tib yam tsawg dua lossis sib npaug li 0.3 hli, kev lag luam thiab mining Tsawg dua los yog sib npaug li 0.5 hli, thiab qhov tseeb yog txhim kho ib qib zuj zus nrog kev tsav tsheb ceev thiab qib load.
Dab tsi yog cov ntsiab lus tseem ceeb ntawm kev tsim kho thiab kev ntsuas xauv rau kev taug qab siab phaj installation?
Ua ntej txhim kho lub phaj siab, ntxuav lub txaj pw ntawm qhov chaw thiab kev tsheb ciav hlau tsis muaj impurities, roj stains thiab xeb, xyuas cov qauv phaj siab tau yoog rau txoj kev tsheb ciav hlau, qhov qhov tsis muaj deformation thiab burrs kom tsis txhob muaj teeb meem. Teem lub phaj siab nrog lub hauv paus kev tsheb nqaj hlau thiab muab tso rau hauv qhov chaw nrog kev sib txawv tsawg dua lossis sib npaug li ± 1mm, xyuas kom lub phaj siab txuas nrog rau lub hauv paus kev tsheb ciav hlau tsis muaj kev cuam tshuam rau sab nraud, tiv thaiv kev ntxhov siab hauv zos ua rau lub siab phaj deformation. Xov cov txhawb nqa siab -lub zog bolts, nruab lub tshuab ntxhua khaub ncaws, xauv hauv cov khoom siv raws li tus qauv torque: 8.8 qib bolts nrog lub zog 350-400N·m, 10.9 qib 500-550N·m, 6509. kev sib txawv. Tom qab kev txhim kho high-ceev railway siab phaj, nws yog ib qhov tsim nyog los ntsuam xyuas lub rwb thaiv tsev tiv thaiv ntau tshaj los yog sib npaug zos rau 5 × 10 ^ 6Ω kom paub meej tias rwb thaiv tsev raws li tus qauv, thiab rau zoo tib yam railway / kev lag luam mining siab phaj, tsuas yog kos tsis muaj loosening tom qab xauv thiab tsis muaj rail lateral hloov. Qhov nruab nrab ntawm cov phaj siab ntawm tag nrho cov kev khiav yog tsis sib xws: 600mm rau high-speed railway, 800mm rau kev tsheb ciav hlau zoo tib yam, 500mm rau kev lag luam thiab mining, qhov sib txawv ntawm qhov yuam kev tsawg dua los yog sib npaug rau 10mm, thiab kev sim ua haujlwm tsuas yog tso cai tom qab tsim nyog txais.
Dab tsi yog qhov ua txhaum cai thiab kev ntsuas ntsuas ntawm cov paib siab hauv kev siv?
Feem ntau qhov ua txhaum ntawm cov phaj siab hauv kev siv suav nrog qhov hnav, siab phaj deformation, bolt loosening, rail lateral displacement, txheej ntog tawm thiab xeb, tag nrho cov uas muaj peev xwm taug qab kev nyab xeeb kev nyab xeeb thiab yuav tsum tau kho raws sij hawm thiab kho. Thaum lub qhov hnav yog ntau dua los yog sib npaug rau 1 hli, qhov kev txwv tsis pub ua tsis tau thiab txoj kev tsheb ciav hlau muaj kev cuam tshuam rau sab nraud. Hloov nrog lub phaj siab tshiab tam sim ntawd, txhim kho lub phaj siab nrog hnav - tiv taus qhov hnyav rau qhov hnyav - cov dej num, thiab xyuas qhov hnav tsis tu ncua. Siab phaj deformation yog tshwm sim los ntawm overload los yog ntau tshaj torque, tshem tawm thiab kho qhov deformed ib feem, hloov ncaj qha yog tsis tuaj yeem kho, rov- xauv raws li tus qauv torque kom tsis txhob deformation dua. Bolt loosening yog torque attenuation los yog anti-loosing tsis ua hauj lwm, rov qab mus rau tus qauv torque, nruab lub caij nplooj ntoos hlav ntxhua khaub ncaws / xauv txiv ntseej, tshuaj xyuas tus nqi torque txhua hli thiab rov kho dua nyob rau lub sij hawm kom tshem tawm loosening. Rail lateral tshem tawm yog vim mismatched siab phaj qauv los yog tsis txaus locking quab yuam, hloov nrog lub adapted siab phaj, hloov mus rau siab zog bolts, re{10}}calibrate txoj hauj lwm rail thiab xauv nws. Txheej ntog tawm thiab xeb yog tiv thaiv- corrosion tsis ua hauj lwm, derust thiab re-kub-dip galvanize, hloov stainless hlau siab daim hlau nyob rau hauv cov ntug dej hiav txwv ntub seem kom tsis txhob xeb los ntawm kev cuam tshuam kev xauv thiab txwv cov teebmeem.
