Derrick crane yog ib yam ntawm cov cuab yeej siv los ua haujlwm nqa thiab thauj. Lub crane nws tus kheej yog kev tsim kho mast-boom tsev. Feem ntau lawv tau siv rau hauv kev sib tsoo pob zeb quarries.
Kev piav qhia dav dav
Ntxiv rau kev siv hauv pob zeb quarries, nws tau nquag siv hauv kev tsim kho, nrog rau qee yam kev lag luam. Piv txwv li, txij li lub thib ob ib nrab ntawm lub xyoo pua puv 19, derrick cranes tau siv nyob rau hauv kev lag luam mining. Cov yam ntxwv tseem ceeb ntawm cov cuab yeej muaj xws li cov hauv qab no: masts, uas yog ua nyob rau hauv daim ntawv ntawm loj hlau lug, booms, struts. Ntxiv rau lawv, kuj tseem muaj cov khoom xws li lub turntable thiab lub tshuab nqa nqa. Cov tom kawg feem ntau muaj xws li cov khoom xws li ib- lossis ob-nruas winch, nrog rau txoj hlua. Ntxiv nrog rau cov npe teev tseg, muaj ob peb yam ntxiv uas tso cai rau koj ntes cov khoom thauj thiab ua lwm yam haujlwm.
Nyob twj ywm
Yog tias peb xav txog kev tsim qauv hauv kev nthuav dav ntxiv, nws tsim nyog sau cia tias muaj ob hom sib txawv ntawm derrick-taps.
thawj hom hu ua cable-nyob. Lub boom ntawm xws li ib tug crane yog mounted nyob rau hauv ib tug mast, ntsia nrog cable braces, nws muaj peev xwm tig 240 degrees. Tsawg zaus, tab sis tseem muaj cov qauv tsim thaum lub crane tuaj yeem tig 360 degree. Tsis tas li ntawd, nws tseem muaj peev xwm tig rau lub qab ntug los ntawm 30-75 degrees.
Hom thib ob ntawm derrick crane yog qhov nyuaj-legged. Nyob rau hauv cov ntaub ntawv no, lub boom yog ntsia nyob rau hauv lub mast, tab sis nrog kev pab los ntawm nruj struts. Txawm li cas los xij, lub kaum sab xis ntawm kev sib hloov, nrog rau cov kaum sab xis ntawm inclination, tseem tsis tau hloov pauv thiab tuaj yeem tig tsis pub dhau ib qho kev txwv xws li cov nyob hauv cable. Raws li qhov ntev ntawm qhov boom ntawm qhov tsim, nws yog los ntawm 20 mus rau 40 meters, thiab qhov siab ntawm mast yog 14-20 meters.
Raws li kev siv cov cuab yeej no hauv kev sib tsoo pob zeb quarries, lawv tau ua haujlwm nyob rau ntawd raws li cov txheej txheem tsis thauj khoom nrog kev thauj khoom sab saum toj, nrog rau kev txav pob zeb loj mus rau sab ntawm cov chaw txua txiag zeb lossis mus rau lub qab ntug overlying.. Muaj qee txoj cai rau kev teeb tsa ntawm cov derrick cranes, uas tswj hwm qhov chaw teeb tsa. Yog tias xav tau ntau tshaj ib qho khoom siv hauv chaw txua txiag zeb, ces qhov thib ob yuav tsum tau muab tso rau sab nraum qhov chaw ua haujlwm ntawm thawj zaug thiab rov ua dua. Hauv lwm lo lus, lawv yuav tsum tsis txhob cuam tshuam ib leeg. Lub peev xwm nqa ntawm tus qauv derrick crane, daim duab uas tau nthuav tawm, yog li ntawm 15 txog 30 tons. Qhov chaw ua haujlwm uas ib qho crane tuaj yeem ua haujlwm yog los ntawm 210 txog 840 m 2. Ntawm no nws tseem tsim nyog them nyiaj rau lub vojvoog ntawm qhov kev txiav txim ntawm crane ntawm lub kaum sab xis ntawm nws txoj kev xav. Yog tias lub kaum sab xis yog 30 degrees, lub vojvoog yuav yog los ntawm 18 txog 36 meters. Yog tias lub kaum sab xis yog 75 degrees, ces lub vojvoogntsws mus rau 6-11 meters.
Qhov txawv ntawm
Vim tias lub derrick crane feem ntau yog cov cuab yeej tuav, nws yuav tsum muaj nws tus kheej zoo uas yuav paub qhov txawv ntawm cov khoom siv zoo sib xws. Thawj thiab tseem ceeb heev kom zoo dua yog txo tus nqi ntawm excavation, loading thiab tsheb thauj mus los li ntawm 1.5-2 zaug. Qhov thib ob tseem ceeb kom zoo dua yog lub peev xwm ntawm kev siv tshuab excavation thiab loading, nrog rau kev thauj mus los ntawm cov pob zeb loj siv ib hom khoom siv nkaus xwb. Qhov kawg yog kev tsim cov cib fim zoo rau kev ua kom tob tob ntawm quarries.
UMK-2M
Txij li thaum muaj ntau yam qauv ntawm cov khoom siv no, nws tsim nyog xav txog qee qhov nrov. Ib qho ntawm cov no yog UMK-2M derrick crane. Lub peev xwm nqa ntawm lub tshuab yog 25 tons. Qhov no yog ib qho tshwj xeeb crane, uas yog tsim los rau hinged los ua ke ntawm steel superstructures ntawm ib leeg-khiav railway choj. Thaum lub sij hawm installation ua hauj lwm, xws li ib tug crane feem ntau yog ntsia rau saum chords ntawm trusses. Cov qauv ntawm cov cuab yeej no suav nrog cov kab kab rov tav thiab 4 kev txhawb nqa, nrog rau ib lub mast, ob lub hauv ntej struts thiab ob tus neeg hloov tau yooj yim. Cov cuab yeej piav qhia kuj muaj lub hauv paus, uas yog nyob mus ib txhis thiab nyob 11 meters. Ib qho tshwj xeeb yog tias nws tuaj yeem hloov qhov ntsuas ntawm lub crane nyob ntawm qhov kev ncua deb ntawm lub ntsiab trusses. Qhov ntau ntawm kev hloov pauv yog nyob rau hauv 5, 8-8 meters. Yooj yim txaus,tias nws muaj peev xwm thauj tau xws li crane raws li pre-installed tshwj xeeb rails. Hauv qhov no, koj tuaj yeem siv ob lub axis ntawm lub qaum chords ntawm lub trusses thiab cov lem uas cov tsheb ciav hlau yob txav mus.
DK-25/40
Derrick-crane 25/40 muaj peev xwm nqa ntau dua li UMK-2M. Nws qhov hnyav tshaj plaws yog 40 tons. Raws li rau nws lub hom phiaj tseem ceeb, nws kuj tseem siv tau rau kev tsim kho ntawm steel superstructures ntawm railway lem. Txawm li cas los xij, qhov no tsis yog tag nrho, thiab nws tau ua haujlwm nyob rau hauv cov xwm txheej uas yuav tsum tau ua kom muaj cov pob zeb ua kom muaj zog thiab tsis yog rau kev tsheb ciav hlau xwb, tab sis kuj rau kev thauj mus los.
Raws li nws tsim, lub crane muaj kab rov tav nrog plaub ceg thiab peb struts. Muaj ib qho me me tab sis tseem ceeb tshwj xeeb hauv kev tsim. Lub rear brace yog hloov tau thiab tsuas yog nqa tensile loads. Vim lub xub ntiag ntawm qhov hloov tau yooj yim strut, nws muaj peev xwm txo qis tus kheej qhov hnyav ntawm cov qauv, thiab nws kuj tseem tuaj yeem tsim cov qauv ntawm tus kheej. Txhawm rau kom muaj kev ruaj ntseg zoo ntawm tag nrho lub platform nyob rau hauv txoj hauj lwm no, pem hauv ntej slopes yog teem rau ntawm ib lub kaum ntse ntse. Nws tuaj yeem ntxiv tias qhov ntev ntawm lub hauv paus, nrog rau qhov dav ntawm DK-25/40 yog tib yam li cov UMK-2M, uas yog, qhov ntev yog 11 meters, thiab txoj kev sib txawv ntawm 5.8. mus txog 8 meters.
MDK-63
Lwm tus kais dej ntawdhais txog cov qauv nruj-legged - qhov no yog derrick crane MDK-63-1100. Cov khoom siv yog tricycle nrog ob txoj hlua. Ib qho tshwj xeeb yog tias lub kaum sab xis ntawm cov struts yog raws nraim 90 degrees. Lwm qhov tseeb nthuav yog tias lub mast ntawm hom crane yog tsau. Nyob rau hauv lub Upper node, nws yog rigidly kho nrog struts, thiab nyob rau hauv lub qis node nrog struts. Tab sis raws li txoj kab dav dav, MDK-63 kom meej meej ua tiav ob lub cranes dhau los, txij li qhov ntau ntawm 6 txog 14 meters. Koj tuaj yeem hloov nws nrog kev pab ntawm plug-in ntsiab uas tau nruab rau hauv qhov chaw tshwj xeeb uas hloov qhov ntev ntawm cov struts. Txoj kab dav dav thiab lub hauv paus ntawm cov cuab yeej tau teeb tsa raws li cov xwm txheej rau kev tso lub crane rau ntawm qhov chaw yuav tsum tau mounted.
Nyob zoo ib tsoom niam txiv kwv tij neej tsas sawv daws
Txhua yam khoom siv saum toj no tau koom nrog cov qauv nruj-legged. Muaj ntau ntau yam uas sib sau ua ke rau hauv ib pawg. Ua ntej, nws yog ib qho tseem ceeb ntawm cov khoom siv tuav cov khoom siv hauv kev tsim cov choj. Qhov thib ob, qhov ntsuas ntawm txhua tus qauv ncaj qha nyob ntawm tus yam ntxwv ntawm cov khoom thauj khoom. Hauv qhov no, peb txhais tau tias lub peev xwm thauj khoom uas cov qauv muaj peev xwm tswj tau ntawm qhov ncav cuag ntawm lub boom. Tsis tas li ntawd, tag nrho cov cranes ntawm hom no muaj ib qho ntxiv, uas nyob rau hauv qhov hnyav hnyav ntawm tag nrho cov qauv.
Zaj lus
Raws li cov lus hauv ntej, peb tuaj yeem xaus tias derrick cranes tau siv dav heev vim lawvyam ntxwv. Tsis tas li ntawd, lawv muaj peev xwm ua tau ntau yam haujlwm zoo, thiab ntau yam qauv tso cai rau koj xaiv cov cuab yeej kom raug raws li qhov ua tau kom ua tau raws li txoj haujlwm.
