Ua rau cov kab mob sib koom ua ke thiab kho

1. Rail sib koom kab mob kev faib tawm

(1) raws li kev sib koom ua ke rail deg xeev: tiv thaiv kev sib koom ua ke, hnav cov pob qij txha tsis sib xws, cov hniav tsis raug, cov hlau stripping pob qij txha, cov pob qij txha loj
(2) Raws li kev sib koom ua ke hauv lub xeev: tig hla lub pob qij txha, tig dawb sib koom ua ke, plam qhov sib koom ua ke, sib koom ua ke nyuaj
(3) raws li lub xeev ntawm cov qauv kev sib koom ua ke: kev sib koom ua ke clamp phaj nyob rau hauv qhov khoov, sab sauv ntawm kev puas tsuaj clamp phaj ntsia liaj qhov rooj torque tsis txaus; fastener txiv ntseej torque tsis txaus, fastener phaj lossis gauge stopper tsis kaw, fastener tsis ua hauj lwm, thiab lwm yam.

2. Qhov ua rau muaj kab mob sib kis

Rail sib koom kab mob, qhov tseem ceeb tshaj plaws yog vim li cas txoj kev tsheb ciav hlau sib koom ua ke muaj nyob rau hauv cov qauv ntawm qhov tsis sib xws, uas ua rau muaj zog ntxiv ntawm lub luag haujlwm ntawm lub log tsheb. Cov nyhuv dynamic ntau dhau kuj tseem ua rau kev txhim kho ntawm qhov tsis sib xws thiab kev loj hlob ntawm qhov ntxiv dynamic quab yuam, uas tseem txhawb txoj kev loj hlob ntawm cov kab mob sib koom ua ke, nws tuaj yeem pom tias qhov tshwm sim thiab kev loj hlob ntawm cov kab mob sib koom ua ke yog kev sib cuam tshuam. Vim yog kev saib xyuas tsis raug tseem yuav ua rau kev txhim kho ntawm kev sib koom ua ke.
(1) cov qauv tsis du Lub tsheb ciav hlau sib koom ua ke hauv cov qauv tsis du, hais txog kev sib koom ua ke rail seam: thaum lub log yog nyob rau ntawm qhov kawg ntawm txoj kev tsheb ciav hlau, qhov kawg tau txais qhov kawg ntawm txoj kev tsheb ciav hlau uas nyob ib sab muaj kev nyiam nce, tsim. ib kauj ruam; lub deflection ntawm lub tsheb ciav hlau sib koom ua ke nyob rau hauv load tsis yog ib tug nruam nkhaus, tab sis ib tug folding kab. Thaum lub kaum sab xis ntawm lub folding, rail slit, kauj ruam peb yam nyob rau tib lub sij hawm, yuav ua rau lub log-rail cuam tshuam, yog li ua rau kev sib koom ua ke ntawm qhov kev tiv thaiv ntxiv.
(2) Ntxiv qhov tsis sib xws Qhov no yog tsim nyob rau hauv lub chav kawm ntawm kev ua haujlwm thaum cov xwm txheej hauv qab no tuaj yeem tsim tau: kev ua haujlwm tsis muaj zog, hnav tsis sib xws ntawm txoj kev tsheb ciav hlau, tsis muaj elasticity.
(3) Dynamic unevenness Dynamic unevenness feem ntau muaj ob qhov xwm txheej: ib qho yog qhov kev sib tw elasticity tsis sib xws thiab thauj khoom hloov pauv, lub log-rail kev sib cuag taw tes trajectory yog wavy unevenness; lwm qhov yog txoj kab muaj qhov tsaus nti dai phaj thiab txoj kev txaj tsis zoo li elastic sinking. Lub dynamic unevenness ntawm txoj kab exacerbates lub poob siab thiab kev co ntawm lub tsheb ciav hlau thaum lub sij hawm ua hauj lwm. Qee zaum kev siv cov thickness tsis sib npaug, tsis sib xws elasticity nyob rau hauv lub tsheb ciav hlau lev board thiab kab kev kho tsis zoo, tag nrho cov intensify lub dynamic unevenness ntawm khiav.

3. kev kho kab mob sib koom ua ke

(1) txhim kho cov khoom siv rail, quenching technology yuav tsum, quenching txheej txheem, rail thiab cleat tsim
(2) nyob rau hauv kev saib xyuas thiab kho kom haum raws li cov pob zeb rail kab yam ntxwv ntawm txoj kev ua haujlwm los txhim kho kev ua haujlwm ntawm cov tsheb ciav hlau sib koom ua ke xws li: raws li qhov kub thiab txias hauv zos hloov, hloov kho raws sij hawm ntawm cov pob qij txha tsis zoo, tswj xyuas haum rail pob qij txha; khaws cov bolts thiab fasteners torque, kom cov kev sib koom ua ke ntawm kev sib txuas kom ruaj khov; sib koom ib feem ntawm lub txaj nyob rau hauv pounding kom zoo pounding zoo; rau kev sib koom ua ke rau kev sib tw tsheb ciav hlau; Rau cov tsos ntawm qhov qis bending splint yuav tsum tau hloov los ntawm lub Upper bending splint thiab shock absorbing splint; Ua tib zoo saib xyuas qhov kev kho ntawm txoj kev tsheb ciav hlau, rau qhov zoo li ntawm txoj kev tsheb ciav hlau tawg tsis sib xws, kev poob qis, kev puas tsuaj thiab lwm yam tsis xws luag thiab tsis zoo los siv vuam, sib tsoo thiab lwm yam kev kho; Txhim kho qhov elasticity ntawm qhov sib koom ua ke ntawm lub txaj, feem ntau yog tshem tawm cov sieve slat thiab tig slurry txaj, hloov lub round ballast.

4. Kev tiv thaiv kev tsheb ciav hlau thiab kev sib koom ua ke ntawm cov txheej txheem kab mob

Ntxiv dag zog rau kev ua haujlwm ntawm steel rail thiab cleat
(1) ntxiv dag zog rau kev tshuaj xyuas ntawm cov ntsia hlau, pom cov ntsia hlau raug mob hnyav thiab cov cleats, yuav tsum tau hloov lub sijhawm;
(2) raws sij hawm straightening ntawm nyuaj khoov rails;
(3) welding raws sij hawm thiab kho rail nto abrasion;
(4) feem ntau ua tib zoo saib xyuas kom nruj cov fasteners, refurbish cov cuab yeej tiv thaiv kev nce toj, xauv lub tsheb ciav hlau, tiv thaiv kev nkag mus, tsis txhob ua kom lub tsheb ciav hlau slit stretched.
Txhim khu kev sib koom ua ke
(1) ntxiv dag zog rau kev sib koom ua ke, ua kom txoj kev txaj puv, thiab kom tamp. Joint rail sleeper cov ntaub ntawv kom deb li deb raws li qhov ua tau zoo sib xws, sib nrug raws li cov kev cai, txhawm rau ua kom cov kev txhawb nqa zoo ib yam.
(2) feem ntau nruj lub clamp ntsia liaj qhov rooj, ua kom cov khoom sib koom ua ke. Vim qhov kev tawm tsam tsis tu ncua ntawm lub tsheb ciav hlau, nws yuav ua rau cov bolts slacked thiab cov sib koom ua ke kom loosen. Qhov tshwm sim yog tias qhov sib koom ua ke tsis tuaj yeem tiv thaiv sab nraud lub zog tag nrho thiab ib tus neeg yuav raug puas tsuaj vim overburdening. Nws kuj ua rau kev hnav ntawm cov splints thiab rail xaus exacerbating lub unevenness ntawm kev sib koom tes. Yog hais tias cov pob qij txha ntawm lub splint vim hnav thiab tsim kua muag thiab rail lub puab tsaig ntawm lub hav zoov ntawm qhov khoob hauv l mm los yog ntau tshaj, yuav tsum tau raws sij hawm ncoo kom tau raws li cov kev cai ntawm daim duab peb sab hlau daim.
(3) raws sij hawm sieve sib koom ua ke ntau yam tsis huv ballast, thiaj li tsis mus tsim ib tug crust, poob elasticity, los yog ua rau tig pulp npuas av nkos, uas ua rau ib tug tseem ceeb unevenness.
(4) Kev tshem tawm raws sij hawm ntawm txoj kev tsheb ciav hlau qhov siab thiab qis cov hniav tsis raug, kev sib koom ua ke ntawm txoj kab tsheb ciav hlau thiab cov kab tsheb ciav hlau nyob hauv cov hniav tsis raug yuav tsum tsis pub tshaj l mm.
(5) nrog rau sab sauv dabtsi yog khoov clipboard kho qhov sib koom ua ke. Ntawm qhov dabtsi yog khoov clipboard yog cov ntawv teev lus dav dav nrog bending rail bender ntawm khoov, ntawm tus nqi ntawm kev khoov feem ntau mus rau 1.2 hli yog qhov tsim nyog. Thaum hloov ntawm cov ntaub ntawv khoov, kev sib koom ua ke ntawm 4 rail sleeper ntau yam ntawm txoj kev tsheb ciav hlau tau tsa, yooj yim kom pom qhov khoob dai phaj thiab ntsia liaj qhov rooj xoob, yog li ntawd, yuav tsum ntxiv dag zog rau mash, zawm lub ntsia liaj qhov rooj.
(6) kev hloov kho raws sij hawm ntawm txoj kev tsheb ciav hlau. Qhov loj ntawm txoj kev tsheb ciav hlau yog qhov tseem ceeb ua rau muaj kab mob sib koom ua ke. Yog li ntawd, qhov sib txawv ntawm txoj kev tsheb ciav hlau yuav tsum tsis sib xws, thiab ua tau raws li cov kev cai ntawm cov kev cai, pom tias qhov loj ntawm kev tsheb ciav hlau yuav tsum tau kho tam sim ntawd.
