Rail Dog Spike Fastening System
CovRailway Dog Spikeyog ib qho hnyav -lub luag haujlwm, L- zoo li tus ntsia thawv ntsia hlau tsim kom ruaj ntseg thiab khi daim hlau rau cov ntoo pw tsaug zog los ntawm kev sib cuam tshuam ntawm kev sib tsoo thiab kev sib txhuam. Ua feem ntau los ntawm qis mus rau nruab nrab- carbon steel qib suav nrog Q235, 35#, 45#, thiab 55# nrog cov ntsiab lus carbon feem ntau yog li ntawm 0.17–0.25% rau lub zog zoo- qhov sib npaug ntawm qhov sib npaug, cov spikes no muaj qhov txawv ntawm qhov sib txawv 15/6}mm (feem ntau{15/10/2019) ib tug chisel los yog wedge-zoo li tus taw tes rau ntoo nkag, thiab ib tug offset lub taub hau nrog ib tug sloped underside tsim los nuv thiab clamp lub hauv paus rail.

Installation & Maintenance Perspective:
- Square Shank Configuration:Tus ntoo khaub lig- ntu (feem ntau 5/8 "los yog 16mm) muab kev sib hloov ua haujlwm nyob rau hauv cov ntoo pw tsaug zog, tiv thaiv cov pob txha los ntawm kev xoob ntawm kev vibrational loads uas yuav ua rau puag ncig- shank fasteners tig thiab poob tuav .
- Lub taub hau hauv qab:Lub hauv qab ntawm lub taub hau spike yog precisely angled kom phim txoj kab nqes ntawm txoj kev tsheb ciav hlau los yog khi phaj, tsim kom muaj kev sib cuag tag nrho uas faib cov clamping quab yuam sib npaug thiab tiv thaiv kev ntxhov siab uas tuaj yeem ua rau kev puas tsuaj ntawm ko taw.
- Chisel Point Geometry:Lub npoo-zoo li tus los yog chisel taw tes yog tsim los ua raws li ntoo grain thaum tsav tsheb, txo cov ntoo sib cais piv rau blunt-taw tes fasteners thaum tsim ib tug neeg kho tshuab interlock uas txhim khu rub- tawm tsis kam .
Kev Saib Xyuas & Kev Pom Kev Ua Haujlwm
- Qhov sib txawv Uniformity:Qhov sib npaug sib npaug ntawm qhov ntev ntawm txoj kev tsheb ciav hlau kom paub meej tias txawm tias cov khoom xa tuaj, tiv thaiv kev ntxhov siab hauv cheeb tsam uas tuaj yeem ua kom cov ntoo degradation lossis spike loosening.
- Periodic Re- tsav tsheb ("Spiking Down"):Vim yog ntoo compression nyob rau hauv load thiab ntuj ntoo txav nrog noo noo hloov, aub spikes yuav tsum tau ncua sij hawm rov- tsav tsheb thaum lub sij hawm txij nkawm cycles kom rov qab lub qub clamping quab yuam- ib tug yam ntxwv yuav tsum tau tu nyob rau hauv elastic fastening systems .
- Kev tiv thaiv corrosion:Kev teeb tsa ib puag ncig dictate txheej txheej yuav tsum tau-kub-dip galvanizing (HDG) rau ntug hiav txwv dej los yog siab-cov av noo, dub oxide rau sab hauv lossis qhuav huab cua, thiab cov roj oiled rau kev tiv thaiv ib ntus thaum khaws cia thiab kev thauj mus los.
