Kev paub txog Rail Spike Anti-Loosing Performance and Compatible Track Types
Dab tsi yog qhov teeb meem tseem ceeb ntawm xoob rail spikes?
Loose rail spikes yuav ua rau txoj kev tsheb ciav hlau tsis raug kho, thiab txoj kev tsheb ciav hlau yuav ua rau kev hloov pauv hloov thaum lub caij tsheb ciav hlau ua haujlwm, cuam tshuam rau txoj kab. Loose rail spikes tsis tuaj yeem xa cov khoom thauj tau zoo, ua rau muaj kev ntxhov siab ntawm lwm cov fasteners thiab ua kom tsis ua hauj lwm ntawm tag nrho cov fastener system. Loose rail spikes yuav ua rau kom muaj kev vibration, ua kom hnav ntawm cov ntsia hlau, cov phaj hauv qab thiab cov neeg pw tsaug zog, thiab ua kom lub neej ua haujlwm luv. Nyob rau hauv siab - kab ceev, xoob rail spikes tej zaum yuav ua rau muaj kev hloov pauv sai sai hauv cov kab zauv ntawm qhov ntev, ua rau muaj kev hem thawj rau kev tsav tsheb. Nyob rau hauv cov kab hluav taws xob, xoob insulated rail spikes yuav ua rau tsis ua hauj lwm ntawm rwb thaiv tsev kev ua tau zoo thiab ua rau muaj teeb meem hauv Circuit Court.
Dab tsi yog cov qauv tsim qauv rau kev tiv thaiv -loosing ntawm rail spikes?
Xov los tiv thaiv- xoob yog feem ntau siv tsim, uas inhibits loosening los ntawm kev sib txhuam xov, xws li siv cov xov zoo los yog cov xov trapezoidal. Anti-loosing washer tsim siv lub elastic deformation ntawm lub tshuab ntxhua khaub ncaws los tsim ua ntej ua ntej kom tsis txhob muaj kev vibration loosening. Cotter tus pin tiv thaiv-loosing qauv txwv tsis pub cov txheeb ze kev sib hloov los ntawm kev hla tus cotter tus pin los ntawm txoj kab tsheb ciav hlau thiab cov txiv ntoo, haum rau cov ntu tseem ceeb. Tshuaj tiv thaiv-loosing tsim siv los tiv thaiv-loosing kua nplaum rau cov xov, uas tsim ib qho kev sib txuas ruaj khov tom qab kho, nrog ntev -ntev los tiv thaiv-loosing nyhuv. Knurled anti{11}}loosing tsim: rail spike shank yog knurled, uas ua rau kom muaj kev sib txhuam tom qab tau embedded nyob rau hauv lub installation qhov, txhim kho anti-loosing peev xwm.
Dab tsi yog qhov txawv ntawm kev tiv thaiv -loosing kev ua tau zoo ntawm kev tsheb ciav hlau spikes rau ntau hom kev khiav?
High - txoj kev tsheb ciav hlau ceev muaj qhov xav tau siab heev rau kev tiv thaiv -loosing kev ua tau zoo ntawm kev tsheb ciav hlau spikes, uas yuav tsum tiv taus siab - zaus vibrations, thiab kev tiv thaiv -loosing qauv yuav tsum tau siv tau ntev. Rail spikes nyob rau hauv hnyav- cov kab tsheb yuav tsum tau tiv thaiv kev cuam tshuam los ntawm lub qag loj loads, thiab kev tiv thaiv -loosing tsim yuav tsum sib npaug zog thiab durability. Cov kab nrawm nrawm muaj qhov xav tau qis dua rau kev tsheb nqaj hlau tiv thaiv - xoob, thiab yooj yim los tiv thaiv - txoj kev xoob tuaj yeem raug xaiv los tswj cov nqi. Kev tsheb ciav hlau hauv nroog tau pib ntau zaus thiab nres thiab kev vibrations hnyav, yog li kev tsheb ciav hlau tsis sib haum xeeb los tiv thaiv- xoob yuav tsum muaj cov yam ntxwv ntawm kev txhim kho sai thiab ntev - lub sij hawm ruaj khov. Rail spikes nyob rau hauv me me - vojvoog kab nkhaus yog raug rau loj lateral quab yuam, thiab kev tiv thaiv -loosing tsim yuav tsum tsom rau tiv thaiv loosening los ntawm lateral vibration.
Yuav ua li cas los txhim kho cov kev tiv thaiv -loosing nyhuv ntawm rail spikes los ntawm installation technology?
Xyuas kom meej tias txoj kab tsheb ciav hlau yog vertically implanted thaum lub sij hawm installation kom tsis txhob muaj zog tsis sib xws los ntawm inclination thiab tiv thaiv loosening. nruj me ntsis tswj lub installation torque thiab nruj raws li tus qauv tsim kom paub meej txaus preload. Siv tshwj xeeb los tiv thaiv- loosening roj los yog lubricating roj rau cov xov ib feem kom txo tau hnav thiab txhim khu kev tiv thaiv -loosing nyhuv. Rau ua ntej - lub tes tsho embedded- hom rail spikes, xyuas kom meej tias lub tes tsho tau ruaj khov thiab sib txuam nrog cov xov hlau rail. Ua kom rov qab kho dua tom qab kev teeb tsa kom tshem tawm me ntsis loosening los ntawm kev vibration pib thiab txhim kho kev tiv thaiv -loosing durability.
Dab tsi yog cov kev sim rau kev tiv thaiv -loosing kev ua tau zoo ntawm kev tsheb ciav hlau spikes?
Kev kuaj xyuas kev vibration: txheeb xyuas qhov xoob ntawm cov tsheb ciav hlau nyob rau hauv ib lub sijhawm tshwj xeeb los ntawm kev simulating lub tsheb ciav hlau ua haujlwm vibration ib puag ncig. torque decay test: tsis tu ncua ntsuas lub rail spike torque tom qab kev teeb tsa los txiav txim qhov kev ua tau zoo ntawm kev tiv thaiv -loosing qauv. Ntawm -site ntev- tshawb nrhiav lub sij hawm: tsis tu ncua xyuas cov xwm txheej nruj ntawm kab rail spikes thiab suav tus nqi xoob. Tsawg-kub thiab siab- qhov ntsuas kub ib puag ncig: txheeb xyuas qhov ruaj khov ntawm txoj kab tsheb ciav hlau tiv thaiv-loosing qauv nyob rau hauv huab cua kub. Impact load test: simulate qhov cuam tshuam ntawm hnyav- tsheb ciav hlau thauj mus los kom paub seb puas muaj kev tiv thaiv{11}}loosing kev ua tau zoo ntawm rail spikes ua tau raws li cov qauv.
