Dab tsi yog Railroad Spikes
Railroad spikes, tseem hu ua railway spikes, yog cov khoom tseem ceeb ntawm kev khiav tsheb ciav hlau. Lawv ruaj cov ntsia hlau mus rau hauv qab crossties, uas zaum ntawm lub txaj ballast thiab nqa cov tsheb ciav hlau thauj mus rau hauv cov qauv khiav. Yog tsis muaj kev txhim khu kev qha, cov tsheb ciav hlau tuaj yeem hloov mus rau hauv kev tsheb thiab txoj kev khiav tuaj yeem poob qhov ntsuas, tsim kom muaj kev pheej hmoo derailment. Kev xaiv Spike yog li cuam tshuam ncaj qha rau kev ruaj ntseg, kev saib xyuas tus nqi thiab kev nyab xeeb ntawm kev ua haujlwm.
Dog Spikes
Aub spikes, tseem hu ua pob taws spikes, muaj lub taub hau dav dua thiab ntev shank dua li txiav spikes. Lawv feem ntau yog siv los ua kom ruaj ntseg rau cov ntoo sib txuas, uas zoo li sib cais lossis tawg hauv cov khoom hnyav. Lub taub hau dav dua faib cov tsheb ciav hlau qhov hnyav tshaj qhov chaw loj dua thiab txo qhov kev pheej hmoo ntawm kev puas tsuaj rau txoj hlua khi. Qhov ntau thiab tsawg muaj xws li 5/8 nti los ntawm 6 nti, 9/16 nti los ntawm 5.5 nti thiab 3/8 nti los ntawm 3.5 nti, nrog rau cov ntaub ntawv xws li A3, Q235, 45 thiab 55 steel. Dog spikes tsis tshua kim thiab yooj yim rau nruab dua li cov ntsia hlau spikes, tab sis lawv tsis tshua muaj txiaj ntsig ntawm cov kab tsheb loj thiab tuaj yeem ua haujlwm xoob dhau sijhawm, yog li yuav tsum tau tsav tsheb ib ntus.
Ntsia Hlau Spikes
Screw spikes nqa cov xov loj thiab tseem ceeb, uas ua rau lawv zoo tagnrho rau cov kab uas muaj zog vibration thiab longitudinal txav. Lawv feem ntau yog siv nrog lub hauv paus daim hlau uas faib cov tsheb nqaj hlau thauj mus rau thaj tsam dav ntawm cov neeg pw tsaug zog. Cov qauv xws li Ss5, Ss8, Ss25 thiab Ss36 series nrog rau UIC 864-1 series spikes. Cov ntaub ntawv raw muaj xws li Q235, 35 steel, 45 steel, 40Mn2 thiab 20MnSi, nrog rau cov chav kawm 4.6, 4.8, 5.6 thiab 8.8. Kev kho deg muaj ntau yam los ntawm cov roj pleev xim rau xim dub, xim xim, zinc thiab kub dip galvanizing.
Sleeper Screw Series Specifications
Ss1 / 130 M22 x 130 mm ntawm 0.451 kg, Ss1 / 150 M22 x 150 mm ntawm 0.478 kg, Ss5 / 150 M24 x 150 mm ntawm 0.545 kg, Ss6 / 150 M26 x 0.8 mm. x 180 mm ntawm 0.636 kg thiab Ss8/150 M24 x 150 mm ntawm 0.548 kg. Square taub hau ntsia hlau spikes muaj los ntawm M22 x 145 mm rau M22 x 195 mm nyob rau hauv 45, 55Q thiab Q235 cov ntaub ntawv. Hexagon taub hau ntsia hlau spikes ua raws li cov cuab yeej cuab tam chav kawm 4.6, 5.6, 8.8 thiab 10.9, nrog tensile lub zog ntawm 400 MPa rau 1000 MPa, yield zog ntawm 240 MPa rau 900 MPa thiab elongation ntawm 22 feem pua rau 9 feem pua. Ib tug ob npaug - taub hau ntsia hlau spike variant yog tsim nyob rau hauv 23 x 174 mm nrog 35 steel.
Yuav Xaiv Txoj Cai Li Cas
Xaiv tsev neeg spike raws li hom pw tsaug zog, lub ntim tsheb thiab kev saib xyuas lub tswv yim. Siv cov ntsia hlau ntsia hlau qhov twg rub- tawm qhov tsis kam, kev vibration tsis kam thiab re-tensioning peev xwm yog qhov tseem ceeb, thiab siv dev spikes rau lub teeb tsheb ciav hlau kab uas tsis tshua muaj nqi installation. Sib piv cov kab uas hla mus rau lub hauv paus phaj qhov thiab qhov chaw pw tsaug zog, xaiv cov khoom vaj khoom tsev los ntawm lub qag load, thiab xaiv qhov chaw tiav los ntawm cov huab cua hauv zos, nrog kub dip galvanizing los yog Dacromet pom zoo rau cov av noo thiab ntug hiav txwv dej.
Kev nyab xeeb thiab kev tu
Tshawb xyuas spikes thaum niaj hnub taug kev taug kev thiab xyuas kom xoob, corrosion thiab lub taub hau puas. Re-tsav dev spikes uas tau ua hauj lwm xoob thiab re- torque ntsia hlau spikes rau tus nqi teev. Hloov cov spikes nrog lub taub hau tawg lossis hnyav corrosion ua ntej lawv tsis ua haujlwm. Khaws cov ntaub ntawv ntawm tus kab mob sib kis los ntawm kev taug qab ntu yog li kev saib xyuas cov peev txheej tau qhia qhov lawv xav tau tshaj plaws.
Kev Ntseeg Tsis Zoo
Ib qho misconception yog tias tag nrho cov spikes yog interchangeable. Dog spikes thiab ntsia hlau spikes muaj tus cwj pwm sib txawv kiag li thiab tau teev tseg rau cov xwm txheej sib txawv. Lwm qhov yuam kev yog xaiv spikes los ntawm tus nqi ib leeg; tus nqi ntawm kev saib xyuas ntxov ntxov feem ntau tshaj qhov txuag ntawm pheej yig dua spikes. Nws kuj yog qhov tsis ncaj ncees lawm uas xav tias cov ntoo kab xyaum tuaj yeem muab luam ncaj qha mus rau cov kab pw tsaug zog, qhov twg dowels thiab cov phaj hauv paus hloov tag nrho cov txheej txheem fastening.
FAQ

Q:Cov cuab yeej cuab tam ntawm cov ntsia hlau ntsia hlau txhais li cas?
A:Cov chav kawm vaj tse xws li 4.6, 8.8 thiab 10.9 txhais qhov tsawg kawg nkaus tensile thiab yield zog ntawm cov ntsia hlau loj, raws li ISO 898-1 cov cuab yeej cuab tam.
Q:Yuav ua li cas tiv thaiv spike corrosion?
A:Qhia meej oiled, xim dub, xim xim, zinc plated los yog kub dip galvanized nto raws li ib puag ncig, nrog zinc thiab galvanized coatings rau cov av noo los yog ntug hiav txwv kab.
Q:Puas yog railroad spikes xav tau kev saib xyuas tsis tu ncua?
A:Yog lawm, spikes yuav tsum tau kuaj xyuas kom xoob, corrosion thiab lub taub hau puas thaum lub sij hawm saib xyuas thiab rov-tsav, re-torqued lossis hloov raws li qhov xav tau.
