Rail Dog Spike Fastening System
Lub Rail Dog Spike yog ib txwm siv, wedge-zoo li tus taug qab fastener cim los ntawm nws qhov offset "dog-} taub hau" profile thiab square-section shank terminating nyob rau hauv ib tug chisel point, tsim tshwj xeeb rau kev ruaj ntseg tiaj tus- hauv qab rails rau ntoo sleepers (ties). Tsis zoo li niaj hnub elastic fasteners uas suav nrog lub caij nplooj ntoos hlav rau calibrated clamping, tus dev spike ua haujlwm los ntawm kev sib txhuam nruj-raws li kev koom tes- nws yog tsav los ntawm pre-drilled qhov nyob rau hauv lub tsheb ciav hlau puag los yog khi phaj ncaj qha mus rau hauv lub cav ntoo substrate, qhov twg lub compression ntawm ntoo fibers nyob ib ncig ntawm nws lub zog rail shank tsim.
Technical Specifications:
| Parameter | Dog Spike | Ntsia Hlau Spike (Coach Screw) | Elastic Rail Clip (piv txwv li, E-Clip) | Caij nplooj ntoos hlav Spike |
|---|---|---|---|---|
| Txoj Cai Fastening | Rigid txhuam (ntoo fiber ntau tuav) | Threaded mechanical interlock | Elastic caij nplooj ntoos hlav deflection | Elastic deformation |
| Primary Sleeper Type | Ntoo nkaus xwb | Ntoo los yog pob zeb (nrog cov ntxig) | Qhob, steel, composite | Ntoo |
| Txoj Kev Txhim Kho | Rauj tsav tsheb (phau ntawv / pneumatic) | Screw tsav (torque-tswj) | Nias-hauv lossis rauj-in | Rauj tsav tsheb |
| Rub -Tshem Tawm | Nruab nrab (grain-dependent) | Siab (0.5-1.0 × siab dua dev) | N/A (tsis rub- tawm raws) | Siab tshaj qhov dav dav |
| Thrust Resistance | Zoo (pab pawg ua haujlwm) | ~ 50% tsawg dua tus dev spike | Siab (calibrated) | Siab tshaj qhov dav dav |
Installation & Maintenance Perspective:
- Offset Head Design:Qhov txawv ntawm L-zoo li lub taub hau nta ib txoj kab nqes hauv qab uas phim lub tsheb ciav hlau ko taw lub kaum sab xis, hooking hla lub flange los tiv thaiv ntsug uplift thaum nthuav tawm qhov chaw tawm tsam rau kev tsav tsheb.
- Square Shank Txoj Cai:Tus ntoo khaub lig-section (feem ntau 14-16mm) tiv thaiv kev sib hloov hauv lub qhov ntoo thiab muab kwv yees li 50% lub zog tuav ntau dua li lub voj voog ntawm qhov sib npaug ntawm qhov sib npaug.
- Chisel Point Termination:Lub npoo- zoo li lub taub hau ntawm cov ntoo fibers ntau dua li txiav lawv, txo qhov sib cais thaum tsim cov fiber ntau compression raws li cov lus qhia rau kev tuav tau zoo.
Kev Saib Xyuas & Kev Pom Kev Ua Haujlwm
- Carbon Steel Qib:Tsim los ntawm nruab nrab- carbon steels xws li Q235, 45#, lossis 55#, nrog cov ntsiab lus carbon feem ntau 0.17-0.25% muab qhov zoo sib npaug ntawm kev tsav tsheb tsis zoo thiab kev pabcuam hauv lub zog.
- Mechanical Property Specifications:AREMA-raws li spikes ua kom pom lub zog tensile yam tsawg kawg nkaus ntawm 70,000 psi, yield point ntawm 46,000 psi, thiab 25% elongation, kom ntseeg tau tias ductility txaus los tiv thaiv kev tsav tsheb yam tsis muaj kev puas tsuaj.
- Corrosion Protection Options:Cov kev kho saum npoo muaj xws li dawb (roj), dub oxide, xim dub, kub -dip galvanizing (HDG), thiab geometric zinc txheej xaiv raws li ib puag ncig raug mob.
