Pob zeb tawg yog cov cuab yeej tseem ceeb hauv kev tsim kho thiab kev lag luam mining, tsim los rhuav tshem cov pob zeb loj thiab cov pob zeb ua kom zoo. Txawm li cas los xij, zoo li txhua lub tshuab hnyav, lawv raug hnav thiab tsim kua muag, thiab ib qho teeb meem tshwm sim uas cov neeg ua haujlwm ntsib yog kev tawg ntawm bolts. Kev nkag siab txog cov laj thawj tom qab qhov tsis ua haujlwm no yog qhov tseem ceeb rau kev saib xyuas thiab kev ua haujlwm zoo.
1. Khoom siv zog:
Ib qho ntawm cov laj thawj tseem ceeb los ntawm bolts tawg hauv pob zeb tawg yog cov khoom siv qaug zog. Nyob rau tib lub sijhawm, kev ntxhov siab thiab kev nyuaj siab los ntawm kev ua rauj tuaj yeem ua rau cov bolts tsis muaj zog. Cov pob zeb tawg ua haujlwm nyob rau hauv cov xwm txheej hnyav, thiab qhov cuam tshuam tas li tuaj yeem ua rau micro-cracks hauv cov khoom siv ntsia liaj qhov rooj. Thaum kawg, cov kab nrib pleb no tuaj yeem nthuav tawm, ua rau qhov tsis ua tiav ntawm lub bolt. Kev tshuaj xyuas tsis tu ncua thiab hloov pauv raws sijhawm tuaj yeem pab txo qhov teeb meem no.
2. Kev teeb tsa tsis raug:
Lwm qhov tseem ceeb uas ua rau kev tawg ntawm bolts yog kev teeb tsa tsis raug. Yog tias bolts tsis raug ntsia raws li cov chaw tsim khoom tshwj xeeb, lawv yuav tsis tuaj yeem tiv taus qhov kev ua haujlwm nyuaj. Kev nruj dhau tuaj yeem ua rau muaj kev ntxhov siab ntau dhau ntawm lub ntsia liaj qhov rooj, thaum qhov kev nruj nruj tuaj yeem ua rau kev txav mus los thiab tsis zoo, ob qho tib si tuaj yeem ua rau lub bolts tawg. Nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov txheej txheem kev teeb tsa ua tib zoo kom ntseeg tau tias lub bolts ntev.
3. Corrosion:
Corrosion yog ib qho yeeb ncuab ntsiag to ntawm cov khoom hlau, suav nrog los ntawm bolts hauv pob zeb tawg. Kev raug dej noo, tshuaj lom neeg, thiab lwm yam ib puag ncig tuaj yeem ua rau xeb thiab degradation ntawm cov khoom siv ntsia liaj qhov rooj. Corroded bolts yog qhov tsis muaj zog thiab ua rau muaj kev ntxhov siab ntau dua. Kev saib xyuas tsis tu ncua, suav nrog kev tu thiab siv cov txheej txheem tiv thaiv, tuaj yeem pab tiv thaiv corrosion thiab txuas lub neej ntawm cov bolts.
4. Ntau dhau:
Pob zeb tawg yog tsim los tswj cov khoom tshwj xeeb, thiab dhau qhov kev txwv no tuaj yeem ua rau muaj kev puas tsuaj loj. Yog tias lub pob zeb tawg yog siv rau ntawm cov khoom siv uas nyuaj dhau los yog ua haujlwm dhau ntawm nws lub peev xwm, lub zog ntau dhau tuaj yeem ua rau cov bolts tawg. Cov neeg ua haujlwm yuav tsum paub txog lub tshuab cov lus qhia tshwj xeeb thiab xyuas kom lawv tsis txhob overloading cov khoom thaum lub sijhawm ua haujlwm.
5. Tsis Muaj Kev Kho Mob:
Kev saib xyuas tsis tu ncua yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm cov pob zeb tawg. Kev saib xyuas tsis saib xyuas tuaj yeem ua rau muaj ntau yam teeb meem, suav nrog kev tawg ntawm bolts. Cov khoom xws li bushings, pins, thiab bolts yuav tsum tau tshuaj xyuas tsis tu ncua rau hnav thiab hloov raws li qhov tsim nyog. Lub sij hawm saib xyuas kev ruaj ntseg tuaj yeem pab txheeb xyuas cov teeb meem muaj peev xwm ua ntej lawv ua rau bolt tsis ua haujlwm.
6. Design Flaws:
Qee zaum, kev tsim ntawm lub pob zeb tawg nws tus kheej tuaj yeem ua rau kev tawg ntawm bolts. Yog tias tus qauv tsim tsis txaus faib kev ntxhov siab lossis yog tias cov bolts tsis muaj lub zog txaus rau daim ntawv thov, kev ua tsis tiav tuaj yeem tshwm sim. Cov neeg tsim khoom yuav tsum xyuas kom meej tias lawv cov qauv tsim muaj zog thiab raug sim nyob rau hauv ntau yam xwm txheej kom txo tau qhov kev pheej hmoo ntawm bolt tawg.
Xaus:
Kev tawg ntawm cov bolts hauv cov pob zeb tawg tuaj yeem raug ntaus nqi rau ntau yam, suav nrog cov khoom siv qaug zog, kev teeb tsa tsis raug, corrosion, overloading, tsis muaj kev saib xyuas, thiab tsim qhov tsis zoo. Kev nkag siab txog cov laj thawj no yog qhov tseem ceeb rau cov neeg ua haujlwm thiab cov neeg ua haujlwm saib xyuas kom ntseeg tau tias muaj kev ntseeg siab thiab ua haujlwm ntawm cov pob zeb tawg. Los ntawm kev ua raws li kev soj ntsuam tsis tu ncua, ua raws li cov txheej txheem kev teeb tsa, thiab tswj xyuas lub sijhawm ua haujlwm ruaj khov, lub neej ntev ntawm cov bolts tuaj yeem txuas ntxiv, ua rau kev txhim kho kev ua tau zoo thiab txo qis hauv kev tsim kho thiab kev ua haujlwm mining.
