Rail Screw Spike Fastening System
CovRailway Screw Spikeyog ib tug precision-engineered threaded fastener tsim los kom ruaj ntseg rails thiab baseplates rau ntoo sleepers los yog qhob pw tsaug zog inserts los ntawm zoo mechanical kev koom tes ntawm helical threads nrog lub tswv tsev khoom. Tsim los ntawm siab -lub zog carbon steel thiab qis- alloy qib suav nrog 35 #, 45 #, 40Mn2, thiab 20MnSi, cov spikes no ua tiav cov khoom siv kho tshuab xws li Qib 4.6 (tensile Ntau dua lossis sib npaug ntawm 400 MPa) rau Qib siab tshaj 8.8 Cov txiaj ntsig zoo ntawm 240-640 MPa.

Installation & Maintenance Perspective:
- Material Displacement Mechanism:Tsis zoo li kev txiav cov xov uas tshem tawm cov khoom, cov ntsia hlau ntsia hlau ntsia hlau tshem tawm cov ntoo fibers radially tawm sab nraud thaum lub sij hawm teeb tsa, tsim kom muaj qhov sib txuas ntawm cov fiber ntau uas ua rau lub zog nruam radial ntawm cov xov flanks.
- Load Angle Optimization:Xov flank kaum ntawm 60℃(metric) los yog 55℃(Whitworth) yog optimized los hloov axial rub - tawm quab yuam mus rau compressive stresses ntawm ntoo fibers es tsis shear stresses uas yuav ua rau fiber ntau tsis ua hauj lwm.
- Dual -Axis Load Teb:Cov xov helix muab cov txheej txheem sib txawv nyob rau hauv ntsug (rub- tawm) piv rau lateral (thrust) cov lus qhia, nrog ntsug muaj peev xwm feem ntau 2-3 npaug siab dua lateral vim xov orientation txheeb ze rau kev taw qhia.
Kev Saib Xyuas & Kev Pom Kev Ua Haujlwm
- Torque-Angle Monitoring:Cov txheej txheem kev teeb tsa hwm zoo ntsuas ob lub torque thiab tig lub kaum ntse ntse ib txhij, tsim lub sijhawm tiag tiag - lub sijhawm torque- lub kaum sab xis uas pom cov xov stripping, hauv qab tawm, lossis cov ntoo tsis zoo thaum lub sijhawm teeb tsa.
- Extraction Tooling:Rov qab-kev sib hloov hydraulic extractors siv kev tswj lub zog (feem ntau 200-500 Nm) kom tshem tawm cov spikes yam tsis muaj xov puas, txawm hais tias tshem tawm torque feem ntau ntsuas 60-80% ntawm kev teeb tsa torque vim ntoo fiber ntau so.
- Automated Track Laying Machine:Siab- cov tsheb ciav hlau tsim tawm tau nruab nrog ntau- spindle hydraulic tsav nruab 8-16 ntsia hlau spikes ib txhij ntawm tus nqi siab tshaj 100 tus neeg pw tsaug zog hauv ib teev thaum lub caij cog qoob loo.
