Rail gnawing yog hais txog lub zog hnav thiab kua muag uas tshwm sim ntawm lub log ntoo thiab sab ntawm tus hlau txuas ntawm lub lag luam ntawm lub lag luam.
Log gnawing trajectory duab
(1) Muaj lub cim ci ntsa iab nyob ntawm ntug kev, thiab nyob rau hauv cov xwm txheej hnyav, muaj burrs lossis ib daim hlab ntawm cov filings hlau peeling.
(2) Muaj cov xim ci ci thiab tawg ntawm sab hauv ntawm lub log ntoo.
(3) Thaum lub crane pib thiab brakes, lub tsheb tsav deviates thiab twists.
(4) Thaum lub crane yog mus, muaj ib qho kev hloov pauv tseem ceeb hauv kev tshem tawm ntawm lub log rims thiab txoj kev hla kev luv luv (10 meters).
(5) Lub tsheb loj yuav ua kom nrov "hiss" thaum nws khiav ntawm txoj kev. Thaum cov gnawing ntawm txoj kev yog qhov tshwj xeeb tshaj yog, nws yuav ua rau "honking" cuam tshuam suab, thiab txawm nce txoj kev.
Vim li cas 1: Cov teeb meem taug qab - qhov txheeb ze tus neeg sib txawv ntawm ob kab ntau tshaj tus qauv. Kev sib txawv ntau dhau ntawm cov txheeb ze nce ntawm txoj kev tuaj yeem ua rau lub tsheb los qaij rau ib sab thiab ua ciav ciav tom. Txoj kev ua: kho cov ciav hlau siab thiab lub tais Cushion.
Qhov tseeb 2: Qhov teeb meem taug qab - ntau dhau ntawm kab rov tav khoov ntawm txoj kev. Vim cov khiav tau dhau qhov ntau, ntau, nws ua rau kev rail tom. Kev daws: Yog tias nws tuaj yeem ua ncaj, ua kom ncaj; Yog tias nws yuav tsis ncaj, hloov nws.
Vim li cas 3: Cov teeb meem taug qab - Sinking ntawm Taug qab Foundation lossis deformation ntawm cov hlau qauv ntawm ru tsev kab. Kev daws: Nyob rau qhov tseeb ntawm tsis muaj kev puas tsuaj ntawm lub tuam tsev muaj kev nyab xeeb, nws tuaj yeem daws cov phiaj yas hauv qab kev sib tw, thiab ntxiv dag zog rau cov qauv hlau ntawm lub ru tsev ci.
Qhov laj thawj 4: Qhov teeb meem log - txoj kab uas hla ntawm ob lub log nquag loj heev. Kev daws: Yog tias qhov tsis sib xws hnav ntawm lub log tread ua rau muaj kev sib txawv ntau dhau, ces tig tau welded, ces tig mus welded, ces tig mus welded, ces tig mus, thiab thaum kawg saum npoo quenched. Rau kev tsheb ciav hlau tom tshwm sim los ntawm kev tsav tsis sib xws ntawm ob tsav lub log treapensions sib npaug lossis cov taper taw teeb kom raug.
Qhov laj thawj 5: Qhov teeb meem log - qhov teeb meem log - cov kab rov tav heev thiab ntsug sib txawv ntawm lub log. Kev daws: Yog tias qhov deformation ntawm tus choj ua rau cov kab rov tav thiab ntsug ntawm cov log loj kom ntau dua qhov ua tau zoo, tus choj yuav tsum raug kho ua ntej ua ntej kom tau raws li cov kev xav tau. Yog tias tseem muaj gnawing ntawm txoj kev khiav, lub log tuaj yeem hloov kho dua.
Tsis muaj teeb meem nrog tus choj, tab sis cov tuab tuab ntawm cov ncoo kom tsim nyog tuaj yeem ntxiv rau hauv lub phaj ruaj ruaj ntawm lub thawv me me. Thaum kho cov kab rov tav sib txawv, ntxiv padding rau ntawm cov ntsug ntawm lub log log. Thaum kho cov kev sib cav ntsug, ntxiv padding ntawm tus kab rov tav dav hlau ntawm pawg log.
