1. Dab tsi yog qhov txawv ntawm txoj kev tsheb ciav hlau thiab lub bolts?
Txoj kev tsheb ciav hlau yog ib qho yooj yim fastener uas tso siab rau nws cov duab (taw kawg, clamping sab sauv kawg) thiab kev sib txhuam rau fixation, feem ntau ntsia los ntawm hammering los yog screwing. Ib tug ntsia liaj qhov rooj, ntawm qhov tod tes, yog ib tug threaded fastener uas yuav tsum tau ib tug txiv ntseej thiab lub tshuab ntxhua khaub ncaws kom ruaj ntseg txoj kev tsheb ciav hlau mus rau lub pw tsaug zog, feem ntau siv nrog lub hauv paus phaj. Spikes yooj yim dua thiab nrawm dua rau kev txhim kho, thaum bolts muab kev ruaj khov, kho tau yooj yim dua. Spikes yog ib txwm muaj nyob rau hauv ib txwm lem, thaum bolts yog nyiam nyob rau hauv niaj hnub high -ceev los yog hnyav- thauj railways qhov xav tau ntau zog. Bolts tuaj yeem nruj los yog xoob yooj yim dua rau kev saib xyuas, thaum spikes yuav tsum tau siv zog ntau dua los tshem tawm.
2. Cov kev tsheb ciav hlau puas tuaj yeem siv nrog cov pw tsaug zog sib xyaw?
Yog lawm, railway spikes tuaj yeem siv nrog cov pw tsaug zog sib xyaw, uas yog ua los ntawm cov ntaub ntawv zoo li fiberglass -cov yas siv zog. Screw spikes yog hom tsim nyog tshaj plaws rau cov neeg pw tsaug zog sib xyaw, vim lawv cov qauv tsim tsim muaj kev sib txuas ruaj khov yam tsis muaj kev sib cais cov khoom sib xyaw (uas tuaj yeem tshwm sim nrog hammered ntau spikes). Cov spikes siv nrog cov neeg pw tsaug zog sib xyaw feem ntau yog coated los tiv thaiv cov tshuaj lom neeg ntawm cov khoom sib txuas thiab cov khoom sib xyaw. Qhov ntev thiab txoj kab uas hla ntawm cov spikes yog matched rau lub composite sleeper lub thickness thiab lub zog, xyuas kom meej fixation txaus. Qhov kev sib xyaw ua ke ntawm spikes thiab composite sleepers yog siv ntau zuj zus vim yog tus neeg pw tsaug zog qhov kev tiv thaiv corrosion thiab qhov kev cia siab ntawm tus spike.
3. Dab tsi yog qhov cuam tshuam ntawm lub tsheb ciav hlau qhov hnyav ntawm txoj kev tsheb ciav hlau?
Cov tsheb ciav hlau hnyav dua ua rau muaj kev kub ntxhov ntau dua thiab kev co ntawm kev tsheb ciav hlau spikes, ua rau muaj kev ntxhov siab ntawm cov spikes. Qhov no tuaj yeem ua rau hnav sai dua, xoob, lossis txawm tias khoov ntawm cov spikes yog tias lawv tsis tsim los rau cov khoom hnyav. Rau hnyav- tsheb thauj khoom thauj, siab- lub zog alloy steel spikes yog siv los tiv thaiv qhov nce ntxiv. Lub spikes 'rub- tawm qhov tsis kam thiab shear lub zog yog qhov tseem ceeb ntawm no, vim tias cov tsheb ciav hlau hnyav tuaj yeem ua rau muaj zog ntau dua kab rov tav thiab ntsug ntawm txoj kev tsheb ciav hlau, hloov mus rau qhov dav. Kev tshuaj xyuas tsis tu ncua thiab kev saib xyuas ntau zaus ntawm cov khoom hnyav - cov kab tsheb thauj mus los xyuas qhov kev puas tsuaj loj, kom ntseeg tau tias cov spikes tuaj yeem tswj tau cov khoom hnyav ntxiv.
4. Puas muaj kev tsim kho tshiab hauv kev tsim tsheb ciav hlau nyob rau xyoo tas los no?
Yog lawm, muaj ntau qhov kev tsim kho tshiab hauv kev tsim kho tsheb ciav hlau nyob rau xyoo tas los no. Ib qho kev tsim kho tshiab yog kev txhim kho ntawm tus kheej -locking ntsia hlau spikes, uas muaj cov xov tshwj xeeb tsim uas tiv thaiv kom tsis txhob xoob ntawm kev co, txo cov kev xav tau ntawm kev tu. Lwm qhov yog siv cov khoom sib xyaw-coated spikes, uas ua ke ntau txheej (xws li zinc thiab epoxy) rau kev txhim kho corrosion, haum rau huab cua puag ncig. Qee qhov spikes tam sim no tau tsim - nyob rau hauv cov sensors uas tuaj yeem saib xyuas nruj thiab xa cov ntaub ntawv mus rau pawg saib xyuas, tso cai rau kev kho kom zoo. Cov kev tsim kho tshiab no txhim kho qhov kev ua tau zoo, txo cov nqi tu, thiab txhim kho kev nyab xeeb tag nrho.
5. Yuav ua li cas rau txoj kev tsheb ciav hlau spikes uas yog xeb me ntsis tab sis tseem siv tau?
Rail spikes uas yog xeb me ntsis tab sis tseem siv tau yuav tsum tau tu thiab tu ua ntej rov siv dua. Ua ntej, cov xeb raug tshem tawm siv hlau txhuam los yog sandblasting kom nthuav tawm cov hlau huv. Tom qab ntawd, cov txheej txheem tiv thaiv corrosion (xws li zinc- nplua nuj xim) yog siv los tiv thaiv xeb ntxiv. Cov spikes yog tom qab kuaj xyuas qhov kev puas tsuaj zais, xws li cov kab nrib pleb lossis khoov, kom ntseeg tau tias lawv ua tau raws li cov qauv siv zog. Yog tias lawv dhau qhov kev tshuaj ntsuam xyuas, lawv tuaj yeem rov qab siv dua hauv qhov tsis yog - cov kev tsheb ciav hlau tseem ceeb, xws li cov kab kab lossis cov lem ib ntus. Cov txheej txheem no txuas ntxiv lub neej ntawm spikes, txo cov khoom pov tseg, thiab txuag nqi piv rau kev hloov pauv nrog cov tshiab.
