Tus Xov Tooj Tus Kheej -Xov Xwm Txheej Txheem Tsim ntawm Kev Sib Tw Sib Tw thiab nws lub luag haujlwm hauv kev txhim kho qhov kev ntseeg tau ntawm kev taug qab Anchorage
Dab tsi yog cov qauv tsim ntawm tus kheej -locking xov qauv ntawm railway spikes?
Cov qauv tsim tseem ceeb ntawm tus kheej -locking xov qauv ntawm railway spikes suav nrogxov txhuas lub kaum ntse ntse, xov profile bevel kaum sab xis thiab xov helix lub kaum sab xis, thiab peb qhov kev txwv no sib koom ua ke txiav txim siab qhov zoo ntawm tus kheej -locking kev ua tau zoo. Lub kaum sab xis ntawm cov xov hlau yuav tsum tau tswj ntawm 3℃thiab 5 degree, uas yog me dua lub kaum sab xis ntawm cov xov khub, kom tus kheej - xauv tuaj yeem ua tiav los ntawm kev sib txhuam quab yuam kom tsis txhob xoob los ntawm kev co. Cov xov profile bevel lub kaum sab xis yog tsim los rau 15 degree, piv nrog 30℃bevel lub kaum sab xis ntawm cov xov zoo tib yam, nws tuaj yeem ua rau thaj chaw sib cuag ntawm cov hniav thiab txhim kho cov kabmob muaj peev xwm. Cov xov helix lub kaum sab xis yuav tsum phim lub kaum sab xis ntawm lub kaum sab xis kom paub meej tias tom qab qhov kev sib txuas yog nruj, lub zog kev taw qhia ntawm cov hniav ntawm cov hniav yog perpendicular mus rau qhov chaw tiv tauj, txo cov kev cuam tshuam ntawm lateral tivthaiv quab yuam ntawm tus kheej -locking kev ua tau zoo. Cov qauv tsim ntawm cov kev txwv no yuav tsum tau hloov kho raws li cov khoom siv spikes thiab ballast txaj hom, thiab lub kaum sab xis ntawm cov ntsia hlau rau hnyav - cov kab tuaj yeem raug txo kom tsim nyog rau 3℃los txhim kho tus kheej -locking effect.
Dab tsi yog qhov kev ua tau zoo sib txawv ntawm tus kheej - xauv xov qauv thiab cov qauv xov zoo tib yam ntawm kev tsheb ciav hlau spikes?
Qhov kev ua tau zoo sib txawv ntawm tus kheej -locking xov qauv thiab cov qauv zoo tib yam xov ntawm railway spikes feem ntau tshwm sim nyob rau hauv peb yam:anti-loosing peev xwm, bearing zog thiab durability. Nyob rau hauv lub siab - zaus vibration ntawm tsheb ciav hlau, kev sib txhuam quab yuam ntawm xov khub ntawm tus kheej - xauv cov qauv spikes yuav tsis attenuate nrog vibration, tab sis yuav nce vim load extrusion, uas muaj peev xwm tuav tau ntev - lub sij hawm anchoring quab yuam; Kev sib txhuam quab yuam ntawm cov xov zoo tib yam spikes yog ib qho yooj yim kom txo tau nyob rau hauv lub zog ntawm kev co, thiab loosening teeb meem tshwm sim ntau zaus. Qhov chaw sib cuag ntawm cov hniav ntawm tus kheej - cov qauv ntsuas phoo yog 20%-30% loj dua li cov xov zoo tib yam, nrog cov kabmob muaj zog dua, uas tuaj yeem tiv taus qhov cuam tshuam ntawm hnyav- tsheb ciav hlau; lub zog ntawm tib yam xov spikes yog concentrated ntawm ob peb cov hniav, uas yog nquag mus rau xov profile tawg. Nyob rau hauv cov nqe lus ntawm durability, cov xov coj tus nqi ntawm tus kheej-locking qauv spikes yog 40% qis dua li cov zoo tib yam threads, thiab cov kev pab cuam lub neej yuav txuas ntxiv mus rau ntau tshaj 10 xyoo, thaum lub sij hawm kev pab cuam lub neej ntawm zoo tib yam xov spikes tsuas yog 5-6 xyoo, uas yuav tsum tau hloov ntau zaus.
Dab tsi yog qhov yuav tsum tau hloov ntawm tus kheej - xauv xov cov qauv ntawm kev tsheb ciav hlau spikes rau ntau hom ballast txaj?
Cov kev hloov pauv ntawm tus kheej -xauv xov cov qauv ntawm kev tsheb ciav hlau spikes rau ntau hom ballast txaj sib txawv, thiab cov tub ntxhais tseem ceeb yog kom phimqhov nruj thiab kev ntxhov siab ntawm lub txaj ballast. Lub txaj tseem ceeb ballast muaj qhov tawv tawv thiab me me deformation, thiab muaj kev xav tau siab rau kev rub tawm - tawm ntawm cov spikes, yog li nws yuav tsum tau txais yuavloj xov profile tus kheej -locking threadsnrog ib tug xov hniav qhov siab Ntau tshaj los yog sib npaug zos rau 3 hli kom nce lub occlusal qhov tob nrog pob zeb, thiab lub rub- tawm kuj yuav tsum ntau tshaj los yog sib npaug zos rau 80kN. Lub pob zeb crushed ballast txaj muaj qhov nruj nruj thiab yooj yim rau deform, yog li nws muaj kev xav tau ntau dua rau kev tiv thaiv -loosing peev xwm ntawm spikes, yog li nws yog ib qho tsim nyog yuav tau txais yuavob - coj tus kheej - xauv xov, uas tuaj yeem cuam tshuam kev vibration kev ntxhov siab los ntawm ob -cov qauv tsim los tiv thaiv qhov sib txawv ntawm spikes thiab sleepers. Lub spikes ntawm slab ballast txaj yuav tsum dhau los ntawm txoj kev slab rau anchoring, yog li nws yuav tsum tau txais yuav.zoo -pitch tus kheej- xauv xov. Cov xov zoo -pitch threads muaj kev sib khi zoo dua qub, uas tuaj yeem tiv thaiv cov dej nag los ntawm kev nkag mus rau hauv qhov anchoring thiab ua rau pob zeb corrosion. Nyob rau tib lub sijhawm, tus kheej -locking kev ua tau zoo-pitch threads yog ruaj khov dua, yoog raws qhov siab -precision installation yuav tsum tau ntawm slab ballast txaj.
Dab tsi yog cov ntsiab lus tseem ceeb ntawm kev ua haujlwm thev naus laus zis rau tus kheej -locking xov qauv ntawm railway spikes?
Cov ntsiab lus tseem ceeb ntawm kev ua haujlwm thev naus laus zis rau tus kheej - xauv xov qauv ntawm kev tsheb ciav hlau spikes yog tsom rau hauv ob qhov txuas:xov dov thiab kev kho cua sov, uas cuam tshuam ncaj qha rau kev ruaj ntseg ntawm tus kheej -locking kev ua tau zoo. Cov xov dov siv cov txheej txheem txias dov, dov kub yog tswj nyob rau hauv chav tsev kub kom tsis txhob xov profile deformation los ntawm qhov kub thiab txias, thiab dov siab yuav tsum tau thov tusyees kom paub meej tias qhov sib txawv ntawm cov xov profile yog tsawg dua los yog sib npaug rau 0.05mm. Cov dov spikes yuav tsum tau quenched thiab tempered, quenching kub yog 850-880 degree, thiab tempering kub yog 450{11}}500 degree, yog li ntawd lub hardness ntawm cov xov ib feem mus txog HRC35-40, txhim kho hnav tsis kam thiab cuam tshuam. Tom qab kev kho cua sov, cov xov yuav tsum yog phosphate nto, thiab lub thickness ntawm phosphating zaj duab xis yog tswj ntawm 5-8μm los txhim kho cov kev sib txhuam quab yuam ntawm cov xov khub thiab ntxiv dag zog rau tus kheej -locking nyhuv. Tom qab ua tiav, qhov kev tshuaj ntsuam mus-tsis-mus yuav tsum tau ua kom ntseeg tau tias qhov kev ntsuas mus ntawm cov xov dhau mus thiab qhov ntsuas tsis mus tsis dhau. Nyob rau tib lub sijhawm, qhov kev ntsuam xyuas los tiv thaiv kev xoob yuav tsum tau ua kom paub tseeb tias qhov kev poob qis ntawm lub zog tom qab kev vibration yog tsawg dua lossis sib npaug li 5%.
Dab tsi yog qhov ntawm - qhov chaw teeb tsa kev ceev faj rau tus kheej - xauv xov qauv ntawm railway spikes?
Qhov ntawm -qhov chaw teeb tsa ntawm tus kheej- xauv xov qauv ntawm kev tsheb ciav hlau spikes yuav tsum tsom mus rau peb yam:anchoring qhov tu, zawm torque tswj thiab installation verticality. Ua ntej kev teeb tsa, nws yog ib qho tsim nyog yuav tsum tau ntxuav cov plua plav thiab cov khib nyiab hauv lub qhov nkuaj, uas tuaj yeem ntxuav nrog lub siab - rab phom cua kom ntseeg tau tias lub qhov yog huv si thiab tsis txhob muaj cov khib nyiab cuam tshuam rau qhov occlusion ntawm cov ntsia hlau loj thiab pob zeb. Lub zawm torque yuav tsum tau kho raws li lub txaj ballast, lub zawm torque ntawm spikes rau ib lub txaj ballast yog 300-350N·m, thiab cov pob zeb crushed pob zeb yog 250-300N·m. Ntau lub zog torque yog ib qho yooj yim ua rau xov profile puas, thiab tsis txaus torque tsis tuaj yeem ua tau zoo ntawm tus kheej - xauv. Lub installation verticality sib txawv ntawm qhov ntsia hlau loj yuav tsum tsawg dua lossis sib npaug li 1 degree, uas tuaj yeem ntsuas nrog tus kav qib. Kev sib txawv ntawm verticality ntau dhau yuav ua rau muaj kev ntxhov siab tsis sib xws ntawm qhov ntsia hlau loj, txo qhov rub - tawm qhov tsis kam thiab tiv thaiv -loosing peev xwm. Tom qab kev teeb tsa, kev ntsuas rub tawm yuav tsum tau ua, qhov piv txwv yog 3 daim ib txhiab daim, thiab rub tawm yuav tsum ncav cuag ntau dua 100% ntawm tus nqi tsim los xyuas kom muaj kev ntseeg siab.
