A rail spike yog ib qho kev thauj khoom -cov kabmob steel fastener siv los thauj cov tsheb ciav hlau mus rau cov neeg pw tsaug zog, ua kom muaj kev sib txuas ruaj khov uas tswj cov kev ntsuas kev ntsuas, tiv thaiv kev tsheb ciav hlau rollover, thiab ua kom ruaj khov thauj khoom ntawm kev tsheb ciav hlau mus rau pw tsaug zog thiab ballast. Yog tias tsis muaj qhov tsim tau zoo, kev sib tw tsheb ciav hlau thiab kev nyab xeeb ntawm kev ua haujlwm tsis tuaj yeem khaws cia.
GNEE RAILkhoom siv rail spikes haum rau GB lub teeb rails 8-30 kg / m, hnyav rails 38-60 kg / m, UIC50/54/60, DIN 536 A55-A120 crane rails, QU70/80/100/120, JIS 15KG–CR1010, AS BS11: 1985, thiab AREMA / ASCE 25–175 lb rails, thiab muab kev pabcuam machining, txheej, thiab fastening system txuam cov kev pabcuam.
Puas yog railroad spikes cam khwb cia?
Tsis yog, tsoos railroad spikes tsis raug nrum; lawv yog forged los ntawm kub- dov carbon steel los yog keeb kwm, wrought hlau. Cov txheej txheem forging ua kom lawv cov ductile thiab muaj zog txaus los tiv thaiv tau tsav mus rau hauv cov ntoo sib txuas yam tsis muaj kev tawg. Cam khwb cia hlau yuav nkig heev rau lub hom phiaj no.
- Khoom siv: Feem ntau qis- carbon lossis me steel Q235, Q345B, C1045, uas tso cai rau lawv khoov dua li tawg.
- Kev tsim khoom: Lawv yog forged los yog "txiav" rau hauv cov duab, tsis nchuav rau hauv pwm.
- Cov ntsiab lus keeb kwm: Ua ntej xyoo 1890, lawv tau ua los ntawm cov hlau wrought.
- Kev zam: Txawm hais tias tus qauv rail spikes yog forged, qee qhov niaj hnub tshwj xeeb fasteners los yog replicas siv rau lwm lub hom phiaj yuav raug cam khwb cia.

Dab tsi yog txoj haujlwm ntawm spikes hauv kev tsheb ciav hlau?
Railway spikes, nrog rau cov dev thiab cov ntsia hlau hom, feem ntau ruaj steel rails rau cov neeg pw tsaug zog (kev sib raug zoo), tswj xyuas qhov tseem ceeb, kev ntsuas qhov tseeb thiab tiv thaiv kev txav mus rau sab nraud lossis longitudinal. Lawv kho cov hlua ruaj khov kom tiv thaiv kev derailment, hloov cov khoom hnyav, nqus cov vibrations, thiab tiv taus qhov kub thiab txias -induced expansion/contraction, ua kom tag nrho cov kev ruaj ntseg thiab kev nyab xeeb.
Lub luag haujlwm tseem ceeb ntawm Railway Spikes:
- Kev ruaj ntseg Rail:Lub luag haujlwm tseem ceeb yog tuav lub tsheb ciav hlau kom ruaj khov tiv thaiv tus neeg pw tsaug zog lossis lub hauv paus phaj kom tiv thaiv kev txav los ntawm lub tsheb ciav hlau txav.
- Kev ruaj ntseg ntsuas:Spikes khaws qhov kev ncua deb (gauge) nruab nrab ntawm ob txoj kev tsheb ciav hlau, uas yog qhov tseem ceeb los tiv thaiv cov tsheb ciav hlau los ntawm derailing.
- Load Transfer:Lawv pab hloov qhov hnyav hnyav ntawm kev hla tsheb ciav hlau los ntawm cov tsheb ciav hlau mus rau cov neeg pw tsaug zog thiab, thaum kawg, mus rau ballast.
- Tiv thaiv kev txav:Lawv txwv ob leeg kab rov tav (lateral) thiab ntsug txav ntawm txoj hlua.
- Kev Siv Thermal Expansion:Lawv tso cai rau me ntsis, tswj kev txav mus los thaum hloov pauv kub thaum tseem tuav lub tsheb ciav hlau hauv qhov chaw, tiv thaiv buckling.
- Vibration Absorption:Lawv pab nqus cov shocks thiab vibrations los ntawm cov tsheb ciav hlau hnyav, uas txo qhov hnav thiab tsim kua muag ntawm txoj kev.
Hom Spikes:
- Dog Spikes:Feem ntau siv rau cov ntoo pw tsaug zog rau lawv qhov yooj yim, siv tau, thiab kev lag luam, tuav lub zog.
