Precise Track Clamping thiab Locking Technology nrog Ntau -Scenario Adaptability
Dab tsi yog qhov tseem ceeb ntawm cov qauv kev faib tawm ntawm cov phiaj xwm siab thiab cov kev qhia tshwj xeeb uas siv tau?
Cov qauv tseem ceeb hauv teb chaws tus qauv ntawm cov phaj siab yog 50-hom, 60- hom thiab 75{11}} hom, thiab cov qauv tseem ceeb txawv teb chaws yog UIC60- hom thiab QU hnyav{13}} hom haujlwm. Cov qauv sib raug zoo raws li lub hauv paus kev tsheb nqaj hlau thiab kev tsheb nqaj hlau hnyav, tsis muaj universal hloov qauv. 50- hom phaj siab haum rau 50kg / m lub teb chaws tus qauv kev tsheb ciav hlau zoo tib yam, qhov dav dav haum rau kev tsheb ciav hlau lub hauv paus thickness, paub txog cov kev txwv yooj yim xauv thiab ua tau raws li qhov tsawg -kev ceev tsav tsheb xav tau ntawm 6 kg / m siab zoo tib yam railway kab {0. siab -kev sib txuas ceev ceev thiab cov kab tsheb ciav hlau zoo tib yam txoj kab tsheb ciav hlau, lub qhov yog nrog cov kab los tiv thaiv - cov kab nrib pleb, qhov kev txwv thiab kev cuam tshuam rau sab nraud yog qhov zoo dua, thiab kev tsav tsheb ruaj khov muaj zog dua . 75- hom phaj siab yog tsim rau 75kg / m high-speed railway main line rail, nrog rau kev sib tw ntawm kev sib tw thiab kev sib tw ntau dua 4% kev sib tw, nrog rau cov kev sib tw thiab kev sib tw ntau dua 0. high-ceev tsav tsheb thiab tshem tawm rail hloov chaw. UIC60-hom yog tsim rau European tus qauv UIC60 rail, QU70-120-hom yog tsim rau kev lag luam thiab mining lifting rail, lub qhov thiab qhov chaw yog tsim raws li cov qauv coj, uas tuaj yeem ncaj qha mus rau kev hla ciam teb engineering thiab kev lag luam thiab mining scenarios.
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 daim hlau yog ntxiv coated nrog hnav- resistant hardened txheej, cov khoom siv zog adapts rau cov kab load qib. Q355B siab phaj yog cov qauv tseem ceeb rau kev siab - kev tsheb ciav hlau ceev thiab hnyav thauj khoom, nrog lub zog tensile Ntau dua lossis sib npaug ntawm 510MPa, yield zog Ntau dua lossis sib npaug rau 355MPa, tsis muaj qhov tawg hauv qhov txias txias, tsis muaj cov yas deformation tom qab xauv, thiab kev qaug zog zoo heev. 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 - dov hnav tsis kam yog nce 3 zaug, yoog rau siab - zaus load cuam tshuam hauv kev lag luam thiab mining. 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 cov kev ntxhov siab tsis muaj 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- ceev railway siab phaj adopts elastic txwv kev koom ua ke qauv, lub qhov yog nrog arc chamfer, haum lub tsheb ciav hlau puag yam tsis muaj ntug khawb, ua - nyob rau hauv elastic gasket, nrog ob qho tib si txwv thiab micro- buffering zog, adapting mus rau lub nruj txwv xav tau ntawm siab - ceev railway ballastless khiav. Ordinary railway siab phaj yog nruj ncaj phaj qauv yam tsis muaj elastic Cheebtsam, lub qhov yog txoj cai - lub kaum sab xis tsim, yooj yim ua thiab tsis muaj nqi, tsom rau cov ntshiab lateral limit, adapting rau me ntsis deformation tej yam kev mob ntawm zoo tib yam railway ballasted khiav. 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 thiab tsis ua hauj lwm. High-Speed railway siab phaj yog txuam nrog 10.9 qib insulating bolts nrog insulating txheej los tiv thaiv conduction, thaum zoo tib yam railway/industrial 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 los yog sib npaug li 0.3 hli, kev lag luam thiab mining Tsawg dua los yog sib npaug li 0.5 hli, thiab qhov raug 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 phaj siab qauv yog yoog rau txoj kev tsheb ciav hlau, lub qhov yog tsis muaj deformation thiab burrs kom tsis txhob muaj teeb meem cuam tshuam rau qhov haum. Teem lub phaj siab nrog lub hauv paus kev tsheb nqaj hlau thiab muab tso rau hauv qhov chaw nrog kev sib txawv ntawm kev teeb tsa tsawg dua lossis sib npaug li ± 1 hli, 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, teeb tsa lub tshuab ntxhua khaub ncaws, ntsuas qhov sib npaug hauv cov khoom raws li tus qauv torque: 8.8 qib bolts nrog torque 350-400N·m, 10.9 qib 500{17}}550.90Nm, qib 650Nm, uniform torque tsis txawv txav. 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 kev ntsuas ntawm cov paib siab hauv kev siv?
Thaum lub siab phaj qhov hnyav dua los yog sib npaug rau 1 hli, qhov kev txwv tsis pub dhau thiab txoj kev tsheb ciav hlau muaj kev cuam tshuam rau sab nraud, nws yuav tsum tau hloov nrog lub phaj siab tshiab ntawm tib tus qauv tam sim ntawd, txhim kho lub phaj siab nrog hnav- tiv taus qhov tawv tawv rau qhov hnyav - lub luag haujlwm, thiab tshuaj xyuas cov qib hnav txhua hli rau kev ceeb toom ntxov. Siab phaj deformation yog tshwm sim los ntawm overload los yog ntau dhau 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 re- deformation nyob rau hauv kev ntxhov siab. 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, rov ntsuas tus nqi torque txhua hli txhawm rau tshem tawm qhov xoob ua rau tsis ua haujlwm. 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-calibrate txoj kev tsheb ciav hlau thiab xauv nws ruaj khov. Siab phaj txheej ntog tawm thiab xeb yog tiv thaiv- corrosion tsis ua hauj lwm, derust thiab re-kub-dip galvanize, hloov stainless hlau siab phaj nyob rau hauv ntug dej hiav txwv seem kom tsis txhob xeb los ntawm kev cuam tshuam kev xauv thiab txwv cov teebmeem.
