Rail Dog Spike Fastening System
Lub Rail Dog Spike yog ib qho forged steel khiav fastener nrog qhov txawv L- lub taub hau thiab tapered square shank, tsim los rau kev txuas ncaj qha ntawm cov ntsia hlau rau cov ntoo pw tsaug zog los ntawm kev cuam tshuam - tsav nkag. Qhov no centuries- qub fastening tov ua hauj lwm nyob rau hauv ib tug yooj yim mechanical txoj cai: lub spike yog hammered los ntawm lub qhov nyob rau hauv lub rail puag los yog khi phaj rau hauv pre-drilled ntoo, qhov twg displaced ntoo fibers compressed nyob ib ncig ntawm lub square shank los tsim kev sib txhuam -raws li tiv thaiv kev tsheb nqaj hlau txav.
Technical Specifications:
| Parameter | Dog Spike | Ntsia Hlau Spike | Caij nplooj ntoos hlav Spike | Elastic Rail Clip |
|---|---|---|---|---|
| Txoj Cai Fastening | Fiber compression (kev sib txhuam) | Threaded mechanical interlock | Elastic deformation | Calibrated caij nplooj ntoos hlav quab yuam |
| Sleeper Compatibility | Ntoo nkaus xwb | Ntoo, pob zeb (nrog ntxig) | Ntoo | Qhob, steel, composite |
| Txoj Kev Txhim Kho | Kev cuam tshuam tsav tsheb | Rotary tsav (torque-tswj) | Kev cuam tshuam tsav tsheb | Nias -in los yog clip driver |
| Installation Ceev | Ceev heev (mechanized) | Nruab nrab (threaded) | ceev heev | Ceev ceev |
| Initial Holding Power | 2,000-4,000 lb | 3,000-6,000 lb | 2,500-4,500 lb | N/A (clamping quab yuam) |
| Kev Kho Kom Zoo | Siab (ib ntus rov- tsav tsheb) | Tsawg | Nruab nrab | Tsawg heev |
Installation & Maintenance Perspective:
- L-Head Configuration:Lub offset lub taub hau tej yaam num nyob rau hauv txoj kev tsheb ciav hlau ko taw, muab ntsug tuav los ntawm ib tug sloped bearing nto uas phim lub rail flange lub kaum sab xis thaum nthuav qhia lub tiaj tiaj tiaj rau cov cuab yeej tsav tsheb.
- Square Shank Txoj Cai:Tus ntoo khaub lig- ntu (feem ntau 14-16 hli) tiv thaiv kev sib hloov hauv cov ntoo thiab ua kom cov ntoo fiber ntau tiv tauj thaj chaw, ua kom muaj kwv yees li 30% siab dua tuav lub zog tshaj qhov sib npaug ntawm qhov sib npaug.
- Tapered Ntsis Geometry:The chisel-point termination features progressive taper that gradually compresses wood fibers during driving, reducing timber splitting while creating a dense fiber collar around the embedded portion .
Kev Saib Xyuas & Kev Pom Kev Ua Haujlwm
- Rub -Tshem Tawm Tus Nqi:Cov ntaub ntawv tuav lub zog muaj li ntawm 2,000-4,000 phaus hauv hardwood sleepers nyob ntawm hom ntoo, cov ntsiab lus noo noo, kev taw qhia ntawm cov nplej, thiab cov kab mob loj.
- Re-Kev Tsav Tsheb:Nyob rau hauv cov tsheb loj, spikes feem ntau yuav tsum tau rov- tsav tsheb txhua 3-5 xyoo raws li ntoo fibers compress thiab so, nrog rau txhua lub voj voog rov tsav tsheb muab kwv yees li 80% ntawm qhov qub tuav lub peev xwm .
- Condition Assessment Indicators:Cov neeg soj ntsuam soj ntsuam kev noj qab haus huv los ntawm kev ntsuas qhov siab ntawm lub taub hau (tseem tau Tsawg dua lossis sib npaug li 1/4 nti saum toj kev tsheb nqaj hlau), kev ntsuas kev xeb, thiab kev tshawb pom ntawm "spike kill" (ntoo deterioration nyob ib ncig ntawm lub shank).
