Kev tsim khoom ntau dua nyob rau hauv txhua qhov chaw ntawm kev tuav cov khoom siv ntau yuav tsum tau txhim kho kev ua haujlwm zoo tshaj plaws thiab muaj txiaj ntsig zoo tshaj plaws ntawm tus nqi qis tshaj.Raws li cov tshuab conveyor ua dav dua, nrawm dua thiab ntev dua, lub zog ntau dua thiab tswj tau ntau dua yuav xav tau.Ua ke nrog kev tswj hwm nruj zuj zus, cov thawj coj ua lag luam tus nqi yuav tsum ua tib zoo xav txog cov cuab yeej tshiab thiab cov kev xaiv tsim raws li lawv lub hom phiaj mus sij hawm ntev rau qhov zoo tshaj plaws rov qab los ntawm kev nqis peev (ROI).
Kev ruaj ntseg yuav zoo dhau los ua qhov tshiab ntawm kev txo nqi.Hauv 30 xyoo tom ntej no, qhov kev faib ua feem ntawm cov mines thiab cov nroj tsuag ua haujlwm nrog cov kab lis kev cai muaj kev nyab xeeb siab yuav nce mus rau qhov chaw uas lawv yuav dhau los ua tus qauv es tsis yog qhov zam.Feem ntau, cov neeg ua haujlwm tuaj yeem tshawb pom cov teeb meem tsis txaus ntseeg nrog cov khoom siv uas twb muaj lawm thiab kev nyab xeeb ntawm chaw ua haujlwm nrog rau kev hloov kho me me xwb.Cov teeb meem no feem ntau tshwm sim raws li cov dej xau loj, ua kom muaj plua plav tawm, hloov txoj siv, thiab cov khoom siv ntau zaus hnav / tsis ua haujlwm.
Cov ntim loj ntawm txoj siv conveyor tsim ntau cov txeej thiab cov ntaub ntawv tsis zoo nyob ib puag ncig ntawm lub cev uas tuaj yeem ua rau tsis muaj zog.Raws li US Occupational Safety and Health Administration (OSHA), daim ntawv hla tebchaws, kev mus ncig thiab kev ntog yog lub luag haujlwm rau 15 feem pua ​​​​ntawm tag nrho cov chaw ua haujlwm tuag thiab 25 feem pua ​​​​ntawm tag nrho cov chaw ua haujlwm raug mob.[1] Tsis tas li ntawd, kev siv ceev nrawm dua ua rau pinch thiab poob cov ntsiab lus ntawm cov khoom siv thauj khoom txaus ntshai, vim tias lub sijhawm tshuaj tiv thaiv tau txo qis heev thaum tus neeg ua haujlwm cov khaub ncaws, cov cuab yeej, lossis cov ceg tawv raug mob los ntawm kev sib cuag.[2]
Qhov ceev ntawm txoj siv conveyor txav, qhov ceev nws deviates los ntawm nws txoj kev thiab qhov nyuaj nws yog rau lub conveyor mus txog qhovtwg system los them rau qhov no, uas ua rau cov to nyob rau hauv tag nrho cov conveyor txoj kev.Vim yog kev hloov ntawm lub load, jammed idlers, los yog lwm yam ua rau, txoj siv sia tuaj yeem nkag mus rau hauv kev sib cuag nrog lub ntsiab ncej, rhuav tshem cov npoo thiab ua rau muaj kev sib txhuam hluav taws.Ntxiv nrog rau qhov cuam tshuam rau kev nyab xeeb ntawm chaw ua haujlwm, cov khoom siv conveyor tuaj yeem kis hluav taws thoob plaws hauv qhov chaw ntawm qhov nrawm heev.
Lwm qhov kev phom sij ntawm chaw ua haujlwm - thiab ib qho uas tau tswj hwm ntau zuj zus - yog cov plua plav tawm.Kev nce ntim ntau dua txhais tau tias qhov hnyav dua ntawm txoj siv ceev dua, uas ua rau muaj kev vibration ntau dua hauv lub cev thiab ua rau huab cua tsis zoo nrog plua plav.Tsis tas li ntawd, cov hniav ntxuav cov hniav zoo li tsis tshua muaj txiaj ntsig thaum lub ntim nce, ua rau muaj kev tawm tsam ntau dua ntawm txoj kev rov qab los ntawm cov khoom siv.Cov khoom abrasive tuaj yeem ua rau cov khoom sib tsoo thiab ua rau lawv txeeb tau, ua rau muaj kev sib txhuam ignition thiab nce nqi txij nkawm thiab kev poob qis.Tsis tas li ntawd, huab cua qis dua tuaj yeem ua rau cov neeg soj ntsuam raug nplua thiab yuam kom kaw.
Raws li txoj siv sia conveyor tau ntev dua thiab sai dua, cov cuab yeej taug qab niaj hnub ua qhov tseem ceeb dua, muaj peev xwm txheeb xyuas cov kev hloov me me hauv txoj kev conveyor thiab them sai sai rau qhov hnyav, ceev thiab drift rog ua ntej lawv overload lub tracker.Mounted feem ntau txhua txhua 70 mus rau 150 ko taw (21 mus rau 50 meters) ntawm qhov rov qab thiab thauj sab - nyob rau hauv pem hauv ntej ntawm lub unloading pulley ntawm lub load sab thiab pem hauv ntej pulley nyob rau sab rov qab - tus tshiab nce thiab nqis trackers siv ib tug tshiab multi- pob khawm mechanism.Torque multiplier thev naus laus zis nrog sensor caj npab los ua ke pom cov kev hloov me me hauv txoj siv txoj siv thiab kho ib lub tiaj tus roj hmab idler pulley kom rov kho txoj siv.
Txhawm rau txo tus nqi ib tonne ntawm cov khoom thauj, ntau qhov kev lag luam tau txav mus rau qhov dav thiab nrawm dua.Cov qauv qhov tsoos tsho zoo li yuav nyob twj ywm tus qauv.Tab sis nrog kev txav mus rau qhov dav dua, kev siv ceev nrawm dua, cov neeg siv khoom siv ntau yuav xav tau kev hloov pauv tseem ceeb rau cov khoom muaj zog ntxiv xws li idlers, log chocks thiab chutes.
Qhov teeb meem tseem ceeb nrog feem ntau tus qauv gutter tsim yog tias lawv tsis tsim los kom tau raws li kev xav tau ntau lawm.Unloading tej khoom los ntawm lub chute hloov mus rau ib tug ceev ceev conveyor txoj siv yuav hloov cov ndlwg ntawm cov khoom nyob rau hauv lub chute, ua rau off-center loading, ua rau kom cov ntaub ntawv khiav tawm thiab plua plav tawm tom qab tawm hauv cheeb tsam.
Cov qauv tsim tshiab kawg no pab cov khoom siv hauv cov khoom siv hauv qhov chaw kaw kom zoo, ua kom muaj kev nkag siab zoo, txwv kev xau, txo cov plua plav thiab txo qis kev raug mob hauv chaw ua haujlwm.Tsis txhob tso cov khoom hnyav ncaj qha mus rau txoj siv nrog kev quab yuam siab, qhov poob ntawm qhov hnyav yog tswj los txhim kho txoj siv sia thiab ua kom lub neej ntev ntawm kev cuam tshuam hauv paus thiab cov menyuam los ntawm kev txwv lub zog ntawm qhov hnyav hauv qhov chaw thauj khoom.Txo kev kub ntxhov ua rau nws yooj yim dua rau kev cuam tshuam cov hnav liner thiab tiab thiab txo qis cov khoom siv luv luv tau ntes ntawm daim tiab thiab txoj siv sia, uas tuaj yeem ua rau muaj kev sib txhuam thiab kev hnav.
Lub modular nyob ntsiag to cheeb tsam yog ntev thiab siab dua li yav dhau los tsim, tso cai rau lub sij hawm rau lub load kom haum, muab ntau qhov chaw thiab lub sij hawm rau huab cua kom qeeb, cia cov plua plav kom zoo dua.Modular tsim tau yooj yim yoog rau kev hloov kho lub thawv yav tom ntej.Lub tsho hnav sab nrauv tuaj yeem hloov tau los ntawm sab nraud ntawm lub chute, es tsis yog yuav tsum tau muaj kev phom sij nkag mus rau hauv chute raws li hauv cov qauv dhau los.Chute npog nrog cov ntaub thaiv plua plav sab hauv tswj cov huab cua raws tag nrho qhov ntev ntawm chute, cia cov plua plav mus rau ntawm daim ntaub thiab nws thiaj li poob rov qab mus rau txoj siv hauv cov kab loj.Lub kaw lus ob lub ntsej muag muaj lub cim tseem ceeb thiab lub foob thib ob hauv ob sab elastomer sawb los pab tiv thaiv kev nchuav thiab plua plav tawm ntawm ob sab ntawm lub chute.
Kev siv ceev ceev dua kuj ua rau muaj kev ua haujlwm siab dua thiab muaj kev hnav ntau dua ntawm cov hniav ntxuav.Cov khoom loj dua tuaj txog ntawm kev kub ceev ntaus cov hniav tseem ceeb nrog ntau lub zog, ua rau qee cov qauv hnav sai dua, drift ntau dua thiab muaj dej nchuav thiab plua plav.Txhawm rau them nyiaj rau cov cuab yeej siv lub neej luv, cov tuam ntxhab tuaj yeem txo tus nqi ntawm cov khoom siv ntxhua khaub ncaws, tab sis qhov no tsis yog ib qho kev daws teeb meem uas tsis tshem tawm qhov kev poob qis ntxiv cuam tshuam nrog kev tu huv thiab qee zaus cov hniav hloov.
Txawm hais tias qee cov tuam txhab lag luam tawm tsam kom tsis txhob hloov cov kev xav tau ntau lawm, tus thawj coj hauv kev lag luam hauv cov kev daws teeb meem tau hloov kho kev lag luam los ntawm kev muab cov hniav ua los ntawm cov khoom siv tshwj xeeb uas tsim los ntawm cov khoom hnyav polyurethane uas tau txiav txim thiab txiav rau ntawm qhov chaw kom ntseeg tau tias cov khoom xa tuaj tshiab thiab ruaj khov.khoom.Siv cov torsion, caij nplooj ntoos hlav lossis pneumatic tensioners, thawj cov tshuaj ntxuav tes tsis cuam tshuam rau txoj siv sia thiab pob qij txha, tab sis tseem tshem tawm drift zoo heev.Rau cov hauj lwm nyuaj tshaj plaws, tus thawj ntxuav siv lub matrix ntawm tungsten carbide hniav teem diagonally los tsim ib tug peb-dimensional nkhaus nyob ib ncig ntawm lub ntsiab pulley.Kev pabcuam teb tau txiav txim siab tias lub neej ntawm polyurethane thawj lub tshuab nqus tsev yog feem ntau 4 npaug ntawm lub neej yam tsis muaj kev rov ua dua.
Siv cov cuab yeej siv kho mob yav tom ntej, automated systems txuas hniav lub neej thiab siv kev noj qab haus huv los ntawm kev tshem tawm cov hniav-rau-siv thaum lub conveyor yog idling.Lub pneumatic tensioner, txuas nrog lub tshuab cua compressed, yog nruab nrog lub sensor uas pom thaum siv txoj siv tsis tau ntxiv lawm thiab cia li thim rov qab cov hniav, txo qis kev hnav tsis tsim nyog ntawm txoj siv thiab ntxuav.Nws kuj txo cov kev siv zog lossi tswj thiab tensioning cov hniav kom zoo tshaj plaws kev ua tau zoo.Qhov tshwm sim yog tsis tu ncua kho hniav nro, txhim khu kev qha tu thiab lub neej ntev hniav, tag nrho tsis muaj kev cuam tshuam tus neeg teb xov tooj.
Cov tshuab tsim los rau kev mus ncig ntev ntawm kev kub ceev feem ntau tsuas yog muab lub zog rau cov ntsiab lus tseem ceeb xws li lub taub hau rub lub taub hau, tsis quav ntsej qhov txaus ntawm "smart systems", sensors, teeb, txuas, lossis lwm yam khoom siv raws li qhov ntev ntawm cov khoom siv.hluav taws xob.Lub zog pabcuam tuaj yeem ua haujlwm nyuaj thiab kim, yuav tsum muaj cov hloov pauv loj, cov kav dej, cov thawv sib txuas thiab cov kab hluav taws xob los them nyiaj rau qhov tsis muaj hluav taws xob poob rau lub sijhawm ua haujlwm ntev.Hnub ci thiab cua fais fab tuaj yeem tsis ntseeg tau hauv qee qhov chaw, tshwj xeeb hauv cov mines, yog li cov neeg ua haujlwm xav tau lwm txoj hauv kev los tsim hluav taws xob kom ntseeg tau.
Los ntawm kev txuas lub microgenerator patented rau lub idler pulley thiab harnessing lub kinetic zog generated los ntawm ib tug txav txoj siv, nws yog tam sim no muaj peev xwm kov yeej qhov muaj teeb meem uas tuaj nrog powering auxiliary systems.Cov tshuab hluav taws xob no yog tsim los ua ib leeg-ib leeg fais fab nroj tsuag uas tuaj yeem hloov kho rau cov qauv kev txhawb nqa idler uas twb muaj lawm thiab siv nrog txhua yam hlau yob.
Tus qauv tsim siv cov hlau nplaum sib txuas los txuas "tsav nres" mus rau qhov kawg ntawm lub rubey uas twb muaj lawm uas sib npaug rau sab nraud.Tus tsav pawl, tig los ntawm kev txav ntawm txoj siv, koom nrog lub tshuab hluav taws xob los ntawm cov tshuab tsav tsheb ntawm lub tsev.Sib nqus mounts xyuas kom meej tias hluav taws xob lossis cov khoom siv ntau dhau tsis coj cov yob mus rau qhov chaw nres tsheb, hloov cov hlau nplaum raug tshem tawm ntawm qhov yob.Los ntawm kev tso lub tshuab hluav taws xob sab nraud ntawm cov khoom siv, qhov kev tsim tshiab tshiab zam kev puas tsuaj ntawm cov khoom hnyav thiab cov khoom siv ntau.
Automation yog txoj hauv kev rau yav tom ntej, tab sis raws li cov neeg ua haujlwm paub txog cov neeg ua haujlwm so haujlwm thiab cov tub ntxhais hluas cov neeg ua haujlwm nkag mus rau hauv kev ua lag luam ntsib cov teeb meem tshwj xeeb, kev nyab xeeb thiab kev saib xyuas kev txawj ntse yuav nyuaj thiab tseem ceeb.Txawm hais tias kev paub txog kev siv tshuab yooj yim tseem xav tau, cov kws tshaj lij kev pabcuam tshiab tseem xav tau kev paub ntau ntxiv.Qhov kev faib ua haujlwm yuav tsum ua rau nws nyuaj rau nrhiav cov neeg uas muaj ntau yam kev txawj ntse, txhawb cov neeg ua haujlwm kom outsource qee cov kev pabcuam tshaj lij thiab ua cov ntawv cog lus txij nkawm ntau dua.
Conveyor saib xyuas ntsig txog kev nyab xeeb thiab kev tiv thaiv kev saib xyuas yuav dhau los ua kev ntseeg siab thiab nthuav dav, tso cai rau cov conveyors khiav lag luam autonomously thiab kwv yees kev xav tau kev saib xyuas.Thaum kawg, cov neeg ua haujlwm tshwj xeeb uas tswj hwm tus kheej (robots, drones, thiab lwm yam) yuav ua rau qee yam haujlwm txaus ntshai, tshwj xeeb tshaj yog nyob rau hauv av mining, raws li kev ruaj ntseg ROI muab cov laj thawj ntxiv.
Thaum kawg, qhov pheej yig thiab kev nyab xeeb tuav ntawm cov khoom loj ntawm cov ntaub ntawv ntau yuav ua rau kev txhim kho ntawm ntau qhov tshiab thiab tsim khoom ntau dua semi-automated bulk khoom tuav chaw nres tsheb.Cov tsheb thauj khoom yav dhau los los ntawm cov tsheb thauj khoom, tsheb ciav hlau lossis cov nkoj thauj khoom, cov tsheb thauj mus los ntev uas txav cov khoom siv los ntawm cov mines lossis quarries mus rau warehouses lossis processing plants, tej zaum yuav cuam tshuam rau kev thauj mus los.Cov kev sib txuas ua haujlwm ntev-ntev no twb tau tsim nyob rau hauv qee qhov chaw nyuaj mus txog, tab sis sai sai no tuaj yeem dhau los ua ib qho chaw hauv ntau qhov chaw hauv ntiaj teb.
