Yuav ua li cas thiaj txuas tau, txhim kho thiab saib xyuas cov Mining Flat Link Chains?
Ua ib lub chaw tsim khoom siv hlau txuas rau 30 xyoo, peb zoo siab los qhia cov hau kev ntawm kev sib txuas, kev teeb tsa thiab kev saib xyuas cov Chains Txuas Tiaj.
1. Cov yam ntxwv ntawm cov khoom
Kev khawb av muaj zog siab tiaj tiaj txuas saw hlau muaj cov yam ntxwv ntawm lub peev xwm loj, tiv taus kev hnav zoo, cuam tshuam zoo thiab lub neej ntev qaug zog.
2. Lub Hom Phiaj Tseem Ceeb thiab Scope ntawm Daim Ntawv Thov
Nws yog dav siv hauv Armored Face Conveyor (AFC) thiab Beam Stage Loader (BSL) hauv cov thee mine.
3. Tus Qauv Ua Haujlwm
MT / t929-2004, DIN 22255
4. Kev Sib Txuas thiab Kev Teeb tsa
4.1 Kev sib txuas ntawm cov saw hlau tiaj tiaj
Qhov kev sib txuas ntawm cov saw hlau tiaj tiaj hauv kev khawb av yog qhov tseem ceeb rau kev ua haujlwm zoo ntawm lub tshuab thauj khoom. Thaum cov saw hlau tawm hauv lub Hoobkas, nws raug sib txuas nrog cov saw hlau ib-rau-ib kom ntseeg tau tias lub scraper nyob hauv kab ncaj thiab qhov ruaj khov ntawm lub scraper nyob hauv nruab nrab qhov. Muab cov saw hlau tiaj tiaj uas sib txuas ua ke rau hauv lub thawv ntim khoom thiab muab daim ntawv lo rau txhua cov saw hlau uas sib txuas ua ke. Cov saw hlau uas sib txuas ua ke yuav tsum tsis txhob siv sib cais. Kev kam rau ua ke yog hais txog qhov ntev tshaj plaws uas tso cai ntawm txhua cov saw hlau sib txuas.
4.2 Kev teeb tsa cov saw hlau tiaj tiaj
Cov saw hlau txuas tiaj tiaj tau sib dhos ua ke kom raug rau ntawm lub tshuab khawb kom ua tau zoo tshaj plaws. Qhov no yuav ua kom ntseeg tau tias qhov kev kam rau ob sab ntawm cov saw hlau raug txo qis thiab qhov kev nruj ntawm cov saw hlau raug tswj tau zoo thaum lub tshuab khawb pib pib. Xyuas kom lub ntsej muag ncaj thiab txo qhov sib txawv ntawm kev ua siab loj.
Cov saw hlau raug teeb tsa ua khub, thiab cov saw hlau ntev thiab cov saw hlau luv raug sib dhos ua ke. Cov sprockets thiab baffles tshiab feem ntau raug sib dhos thaum teeb tsa cov saw hlau txuas tiaj tiaj tshiab.
Xyuas kom tseeb tias cov saw hlau tiaj tiaj tsis khiav thaum nws raug teeb tsa thawj zaug yam tsis muaj kev lav ris txog kev siv roj nplua nyeem. Yog tias nws khiav yam tsis muaj roj nplua nyeem, cov saw hlau yuav hnav sai sai.
Xyuas kom tseeb tias cov txheej txheem tensioning kom raug yog qhov tsim nyog rau cov scraper conveyors thiab cov tshuab hloov pauv. Tshawb xyuas qhov kev nruj ua ntej txhua hnub kom tsim tau qhov kev nruj tsim nyog rau txhua txoj saw. Vim tias txoj saw nws tus kheej thiab nws txoj kev koom tes nrog lub conveyor yuav tsum tau khiav hauv qhov chaw, ob peb lub lis piam thawj zaug ntawm kev ua haujlwm ntawm cov khoom siv yog qhov tseem ceeb heev.
5. Kev Txij Nkawm Cov Saw Txuas Tiaj
5.1 Kev Ua Haujlwm
Cov saw hlau thauj khoom siv scraper, cov khoom siv scrapers thiab cov txuas txuas (cov khoom sib txuas) yog cov khoom siv tau yooj yim, uas yooj yim hnav thiab puas tsuaj thaum siv dua. Yog li ntawd, kev saib xyuas cov saw hlau tiaj tiaj yog qhov tseem ceeb heev kom ua kom lub neej ua haujlwm ntawm cov saw hlau ntev dua thiab xyuas kom muaj kev pheej hmoo tsawg kawg nkaus ntawm kev ua tsis tiav ntawm cov saw hlau.
Tswj kom qhov chaw ua haujlwm ncaj nraim li sai tau.
Yog tias lub ntsej muag ua haujlwm tsis ncaj, nws tuaj yeem ua rau muaj ntau qib sib txawv ntawm kev hnav thiab ntev ntawm cov saw hlau.
Lub kaum sab xis ntawm sab nraub qaum ntawm lub tshuab txiav nyom raug txo kom tsawg. Yog tias nws nruj dhau, nws yuav ua rau lub zog thiab cov saw hlau hnav ntau ntxiv.
Siv cov txheej txheem tswj hwm saw hlau kom ntseeg tau tias txhua qhov kev ua haujlwm tau kawm thiab cov kev coj ua zoo tshaj plaws tau ua tiav raws li kev taw qhia ntawm tus neeg tsim khoom siv conveyor, ua raws li cov txheej txheem, tswj thiab khaws cov ntaub ntawv.
5.2 Cov lus qhia txog kev saib xyuas
Hauv qee qhov chaw tsuas thee, kev saib xyuas cov saw hlau tiaj tiaj yog qhov tseem ceeb rau tus neeg teb xov tooj qhov kev lees paub ntawm qhov kev sib zog ntawm cov saw hlau, uas tuaj yeem tswj tau qhov kev ua tau zoo ntawm cov saw hlau. Vim tias qhov xwm txheej ntawm kev txo qhov nrawm yog ib qho tseem ceeb los tiv thaiv kev ua tsis tiav ntawm cov saw hlau. Cov hauv qab no yog cov ntsiab lus tseem ceeb, thiab cov lus qhia los ntawm tus neeg tsim khoom siv thauj khoom yuav tsum tau ua raws li.
- Xyuas qhov kev nruj ua ntej txhua hnub, tshwj xeeb tshaj yog ob lossis peb lub lis piam ua ntej kev teeb tsa tshiab thiab kev ua haujlwm ntawm cov saw hlau.
- Tshawb xyuas lub chute conveyor ua ntej pib kom paub tseeb tias tsis muaj qhov tsis zoo lossis teeb meem pom tseeb.
- Hloov lub scraper thiab saw hlau uas puas lawm sai li sai tau.
- Tshem tawm cov saw hlau uas puas lawm lossis tawg thiab xyuas seb cov saw hlau uas nyob ib sab puas ntev. Yog tias nws tsis ua raws li qhov yuav tsum tau ua, yuav tsum tshem tawm raws sijhawm. Yog tias cov saw hlau ntawd puas lawm, cov saw hlau ntawm ob sab yuav tsum tau hloov tib lub sijhawm kom thiaj li ua tau khub ntawm cov saw hlau.
- Tshawb xyuas cov saw hlau, baffles thiab sprockets uas puas lawm thiab hloov lawv yog tias tsim nyog.
- Tshawb xyuas lub scraper kom paub seb puas muaj cov khoom siv uas xoob, ploj lawm thiab puas lawm.
- Xyuas seb txoj saw puas puas hnav thiab ntev. Vim tias kev hnav lossis ntev sab hauv qhov txuas (qhia tias muaj kev thauj khoom ntau dhau) lossis ob qho tib si yuav ua rau txoj saw ntev.
Thaum lub saw hlau tiaj tiaj raug thauj khoom ntau dhau thiab ncab, nws pom tseeb tias muaj kev hloov pauv, ua rau muaj kev nce ntxiv ntawm qhov ntev ntawm lub saw hlau. Qhov no yuav cuam tshuam rau tus lej ntawm cov txuas sib ze, ua rau cov saw hlau tsis sib phim. Hauv qhov no, qhov cuam tshuam yuav tsum tau hloov, thiab yog tias cov saw hlau hnav, cov saw hlau ntawm ob sab yuav tsum tau hloov tib lub sijhawm kom tswj tau kev sib phim ntawm cov saw hlau.
- feem ntau, cov saw hlau no ncab tau zoo thiab yuav rov qab mus rau qhov qub tom qab tshem tawm cov khoom siv. Qhov hnav sab hauv ntawm qhov txuas yuav ua rau lub suab ntawm cov saw hlau nce ntxiv, qhov loj sab nraud ntawm qhov txuas yuav tsis hloov pauv, tab sis qhov ntev tag nrho ntawm cov saw hlau yuav nce ntxiv.
- nws raug tso cai kom nce qhov suab ntawm cov saw hlau los ntawm 2.5%.
6. Kev Thauj Mus Los thiab Kev Khaws Cia Cov Saw Txuas Tiaj Tiaj
a. Ua tib zoo saib xyuas kev tiv thaiv xeb thaum lub sijhawm thauj mus los thiab khaws cia;
b. Lub sijhawm khaws cia yuav tsum tsis pub tshaj 6 lub hlis kom tiv thaiv kev xeb thiab lwm yam los ntawm kev txo lub neej ua haujlwm.
