4 Lub Ntsiab Hom Rail Screw Spike
Oct 20, 2025
Rail ntsia hlau spikes yog railway fasteners uas nws lub luag haujlwm yog kho txoj kab kom cov ntsia hlau tau nruj nreem nias rau ntawm qhov pw tsaug zog thiab subgrade. Lawv yog threaded rau hauv cov ntoo pw tsaug zog los yog mus rau hauv ib tug dowel nyob rau hauv ib tug ua vaj tse pw, thiab lawv rub- tawm tsis kam tuav lub tsheb ciav hlau nyob rau hauv txoj hauj lwm tiv thaiv ntsug, lateral thiab longitudinal zog. Nyob ntawm seb lub taub hau zoo li cas thiab lub kaw lus fastening, ntsia hlau spikes tau muab faib ua plaub tsev neeg loj.
1. Ss Series Sleeper Screws
Ss series yog ib tsev neeg ntawm cov rooj zaum pw tsaug zog uas tau xaiv los ntawm hom thiab ntev, xws li Ss1/130, Ss1/150, Ss2/180, Ss5/150, Ss6/150, Ss7/180, Ss8/140 thiab Ss8/150. Lawv tau siv rau hauv cov txheej txheem pw tsaug zog nrog cov yas dowels thiab muaj nyob rau qib 4.6 txog 8.8. Lub rooj qhia txog qhov ntev thiab qhov hnyav rau ntau hom.
| Hom | Specification | Qhov hnyav / kg | Nto | Txuj |
|---|---|---|---|---|
| SIB 1/130 | M22 x 130 | 0.451 | Ntuj, zinc, xim, roj | UIC, AREMA, GB, lossis ib daim duab |
| SIB 1/150 | M22 x 150 | 0.478 | Ntuj, zinc, xim, roj | UIC, AREMA, GB, lossis ib daim duab |
| Ss2/180 | M22 x 180 | 0.595 | Ntuj, zinc, xim, roj | UIC, AREMA, GB, lossis ib daim duab |
| Ss5/150 | M24 x 150 | 0.545 | Ntuj, zinc, xim, roj | UIC, AREMA, GB, lossis ib daim duab |
| Ss6/150 | M26 x 150 | 0.702 | Ntuj, zinc, xim, roj | UIC, AREMA, GB, lossis ib daim duab |

| Ss8/140 | M24 x 140 | 0.528 | Ntuj, zinc, xim, roj | UIC, AREMA, GB, lossis ib daim duab |
| Ss8/150 | M24 x 150 | 0.548 | Ntuj, zinc, xim, roj | UIC, AREMA, GB, lossis ib daim duab |
2. Square Head Ntsia Hlau Spikes
Square lub taub hau ntsia hlau spikes muaj lub taub hau square tsav thiab lub taub hau threaded, ua rau ntau thiab tsawg xws li M22 x 145, M22 x 155, M22 x 165, M22 x 185 thiab M22 x 195. Lub taub hau square yog tsav nrog lub qhov (socket) thiab muab qhov zoo tsav yam tsis muaj cam - tawm. Cov ntaub ntawv feem ntau yog 45 #, 55Q, Q235 lossis raws li qhov xav tau, nrog rau qhov chaw los ntawm ntuj rau zinc, xim thiab roj. Cov qauv yog UIC, AREMA, DIN lossis GB, lossis cov neeg siv khoom kos duab thiab cov qauv.
3. Hexagon Ntsia Hlau Spikes
Hexagon ntsia hlau spikes muaj lub taub hau hex thiab yog tsim los rau fastening systems qhov twg cov ntsia hlau loj yog ntsia nrog ib tug ciaj ntswj los yog lub hwj chim socket. Lawv muaj nyob rau qib 4.6, 5.6, 8.8 thiab 10.9, nrog cov ntaub ntawv los ntawm Q235 thiab 35# txog 45# thiab 40Cr rau cov chav kawm siab dua. Lub shank yuav tsum ua tau raws li qhov yuav tsum tau ua nruj me ntsis: cov khoom siv raw tshwj xeeb yog siv kom cov ntsia hlau loj tuaj yeem ncaj tsis tawg tom qab txias khoov li 30 degrees. Cov npoo muaj xws li dawb (roj), oxide dub, zinc, HDG, wax, bitumen, Dacromet thiab sherardizing.
4. Ob npaug -Lub taub hau ntsia hlau ntsia hlau
Qhov ob - taub hau (ob- kawg- taub hau) ntsia hlau ntsia hlau muaj lub taub hau ntawm txhua qhov kawg ntawm lub shank: ib kawg yog tsav mus rau hauv lub pw tsaug zog thiab lwm qhov kawg tseem nyob saum lub tsheb ciav hlau los koom nrog lub caij nplooj ntoos hlav clip hauv lub kaw lus fastening. Cov qauv tsim yog nrov nyob rau hauv African railways, qhov twg cov ntsia hlau loj thiab clip tsim ib qho yooj yim, ruaj khov fastening rau pob zeb pw. Txhawm rau ua kom tau raws li qhov yuav tsum tau ua nruj me ntsis ntawm daim ntawv thov no, cov khoom siv tshwj xeeb yog siv kom cov ntsia hlau ncaj ncaj tsis tawg tom qab khoov 30 degrees lossis ntau dua. Qhov loj me yog 23 mm x 174 mm, nyob rau qib 4.6, 5.6, 8.8 thiab 10.9, nrog cov ntaub ntawv raw Q235, 35# thiab 45#, thiab qhov chaw tiaj (oiled), bluing, zinc thiab HDG.
Yuav ua li cas cov qib thiab cov ntaub ntawv kab
| Qib | Khoom siv | Tensile zog | Yield zog | Elongation |
|---|---|---|---|---|
| 4.6 | Q235 | 400 MPa | 240 MPa | 22% |
| 5.6 | 35# | 500 MPa | 300 MPa | 20% |
| 8.8 | 45# | 800 MPa | 640 MPa ua | 12% |
| 10.9 | 40 Cr | 1000 MPa | 900 MPa rau | 9% |
Txhua chav kawm dhau qhov kev ntsuas txias txias ntawm 90 degrees yam tsis muaj kev tawg. Qhov saum npoo tiav yog xaiv raws li qhov chaw corrosion: dawb oiled rau qhuav tej yam kev mob, zinc los yog HDG rau cov av noo thiab ntug hiav txwv dej, thiab Dacromet los yog sherardizing rau txhoj puab heev industrial puag ncig.
