Mining hlau hlua yog ib qho ntawm cov khoom siv tseem ceeb tshaj hauv kuv, thiab kev nyab xeeb ntawm txoj hlua hlau txiav txim siab txog kev nyab xeeb ntawm ntau tus neeg ua haujlwm. Mining hlau hlua tam sim no siv ntau dua rau mining round strand wire rope thiab mining triangular strand wire rope.
Nquag, thaum txoj kab uas hla yog tib yam, qhov softness yog zoo dua li ntawm daim duab peb sab strand, thiab tawg nro ntawm daim duab peb sab strand hlau hlua yuav ntau dua. Txawm li cas los xij, vim nws txoj kev sib hloov coefficient siab, nws tsis yog qhov tsim nyog rau kev siv qhov tob tob. Nws yog ib qho yooj yim rau defects xws li oiliness. Round strand hlau hlua muaj qhov yooj yooj yim, uas tsis txhob muaj kev ntxhov siab thiab txo qhov kev sib txhuam ntawm cov hlau hlau. Nyob rau tib lub sijhawm, kev ua haujlwm ntawm kev khoov tsis kam thiab qaug zog ua haujlwm siab dua li ntawm daim duab peb sab strand hlau hlua.
Thaum pib, kev siv hauv tsev yog triangular strand mining hlau hlua, thiab Baiket tau qhia txog cov hlua khi hlua khi uas tsim los ntawm WDI hauv Tebchaws Europe thiab Lub Tebchaws Yelemees rau hauv Suav teb. Nws tau hloov pauv tsis hloov pauv hauv Suav teb thiab txhim kho kev nyab xeeb ntawm cov mines hauv tsev.
Raws li cov ntsiab lus, daim duab peb sab strand hlau hlua tsis haum rau kev ua haujlwm zoo sib sib zog nqus! Tam sim no, feem ntau ntawm kev sib sib zog nqus mine hlau ropes tam sim no yog ua los ntawm round strand xaim hlua, thiab nws kuj tau taw qhia nyob rau hauv "Basic Theory of Mine Hoisting System" tias qhov torsion ntawm cov hlua hlau ua rau muaj kev ntxhov siab ntawm cov hlau. txoj hlua tsis sib npaug, thiab qhov tshwm sim ntawm torsion yuav ua li cas? Lub overload ntawm sab hauv thiab sab nraud strand hlau hlua, lub overload ntawm cov hlua hlau twisted nyob rau hauv tib txoj kev taw qhia yog tshwj xeeb tshaj yog tseem ceeb, thiab sab hauv strand yog stressed los ntawm ib tug loj npaum li cas, uas yog 4.47 lub sij hawm ntawm lub sab nrauv strand. Yog li ntawd, qhov sib sib zog nqus zoo sib sib zog nqus hoist tsis haum rau kev siv daim duab peb sab strand hlau hlua twisted nyob rau hauv tib txoj kev, thiab round strand hlau hlua tau dhau los ua thawj xaiv!
