Q: Dab tsi yog qhov zoo ntawm cov ntsia hlau spikes tshaj txiav spikes?
A:Screw spikes muab cov txiaj ntsig tseem ceeb:
Siab dua rub - Tawm Tawm:Cov threads muab ib tug ntau zog tuav nyob rau hauv lub pw tsaug zog.
Tsawg Sleeper Damage:Lawv tsis cais ntoo sleepers zoo li tsav spikes tau.
Reusability:Lawv tuaj yeem raug muab tshem tawm thiab rov siv dua hauv tib lub qhov yog tias tsis muaj kev puas tsuaj.
Precise Installation Torque:Lawv tuaj yeem ntsia tau rau ib qho tshwj xeeb torque, kom ntseeg tau tias muaj zog tuav.
Q: Dab tsi yog cov qauv thoob ntiaj teb rau rail spikes?
A:Ntau lub teb chaws thiab cheeb tsam muaj lawv tus kheej cov qauv. Cov feem ntau muaj xws li:
AREMA:American Railway Engineering thiab Maintenance- ntawm -Txoj Kev Koom Tes Cov Qauv, muaj nyob hauv North America.
EN Standards:European cov cai (piv txwv li EN 13479) rau kev tsheb ciav hlau fasteners.
BS Standards:British qauv.
IS Standards:Indian qauv.
GB Standards:Suav teb cov qauv.
Cov qauv no tswj hwm qhov ntev, cov khoom zoo, cov khoom siv kho tshuab, thiab cov txheej txheem txheej txheej.
Q: Yuav ua li cas tuav lub hwj chim los yog rub- tawm qhov kev tiv thaiv ntawm tus ntsia hlau loj?
A:Rub- tawm qhov tsis kam yog sim siv lub ntsuas ntsuas hydraulic lossis tshuab rub lub ntsuas. Lub spike yog ntsia rau hauv ib qho kev sim pw tsaug zog raws li specification. Tom qab ntawd tus tester siv lub zog upward kom txog thaum lub spike rub tawm. Lub zog siab tshaj plaws uas tau sau tseg yog qhov kev rub tawm ntawm qhov sib tw - tawm tsis kam, ib qho kev ntsuas tseem ceeb rau kev tswj kom zoo.
Q: Lub luag hauj lwm dab tsi ua cov rail spikes ua si nyob rau hauv kev sib tw circuit signaling?
A:Nyob rau hauv ib txwm lem, spikes tuaj yeem ua teeb meem teeb meem. Vim tias lawv yog cov hlau thiab txuas cov tsheb ciav hlau mus rau hauv av (los ntawm kev pw tsaug zog thiab ballast), lawv tuaj yeem tsim ib qho luv luv Circuit Court, cuam tshuam cov hluav taws xob tam sim no siv hauv kev khiav tsheb ciav hlau los xyuas cov tsheb ciav hlau. Insulated lub tes tsho los yog tshwj xeeb coated spikes yog qee zaum siv hauv cov chaw taw qhia kom tiv thaiv qhov no.
Q: Dab tsi yog "tus tsav dav hlau" thiab nws ua haujlwm li cas?
A:Tus neeg tsav tsheb loj yog lub zog muaj zog, siv rauj siv los tsav cov hlais rau hauv cov ntoo pw. Cov neeg tsav dav hlau niaj hnub no feem ntau yog cov cuab yeej hydraulic lossis pneumatic mounted ntawm cov cav tov tu. Lawv xa cov kev sib raug zoo, siab - cuam tshuam rau kev tsav tsheb nrawm nrawm thiab mus rau qhov tseeb qhov tob, txhim kho kev ua haujlwm zoo thiab kev nyab xeeb ntawm cov neeg ua haujlwm piv rau phau ntawv hammering.
