Hluav taws xob ib leeg nqaj ncua kev kawm ntawv crane txij nkawm txoj kev tsim kho
Ua ntej, hluav taws xob ib leeg-nqaj ncua kev kawm ntawv crane khoom saib xyuas
Lub tshuab nqa hnyav Q=3 tons, ncua L=13.5 meters, nqa qhov siab H=9 meters, tsheb ceev 20 meters / min.
Qhov thib ob, kev npaj ua ntej cov khoom siv
(1) Kev xaiv cov khoom siv hauv tsev
Cov khoom siv ntawm qhov chaw yuav tsum muaj qhov chaw txaus kom tau raws li qhov xav tau ntawm cov khoom siv flipping thiab nqa, thiab lub xaib yuav tsum muaj cov khoom siv hluav taws xob txuas rau lub tshuab vuam thiab lwm yam khoom siv hluav taws xob.
(2) Kev npaj cov khoom siv thiab khoom siv
Thaum lub sijhawm tsim kho, 2 lub tshuab vuam, 2 txheej ntawm oxygen acetylene, 2 txheej ntawm tes hoist, ntoo ntaiv, nqa iav thiab crane yog xav tau, muab los ntawm Party A.
(3) Kev npaj cov ntaub ntawv
Cov steel rails, platen, splints, bolts, daim hlau ua iav, cov ntaub ntawv rau zawv zawg hlau thiab vuam rods siv nyob rau hauv qhov project no yuav tsum txaus raws li qhov xav tau.
(4) Kev npaj cov neeg ua haujlwm
Cov neeg ua haujlwm koom nrog hauv txoj haujlwm no: 2 tus kws tshaj lij hluav taws xob, 2 tus kws kho mob, 2 tus kws kho mob, 2 tus neeg ua haujlwm hoist, thiab 1 tus neeg saib xyuas kev nyab xeeb.
Thib peb, qhov kev thov kev ruaj ntseg tseem ceeb hauv cov txheej txheem ntaus ntawv
Cov neeg ua haujlwm tsim kho koom nrog hauv txoj haujlwm no yuav tsum ua raws li cov cai tswj kev nyab xeeb ntawm txhua hom haujlwm thiab yuav tsum tsis txhob ua txhaum txoj cai.
Plaub, cov txheej txheem ntawm cov khoom siv
(1) Cov khoom siv taug qab: Ua ntej ntawm tag nrho cov, qhov chaw raug txheeb xyuas, thiab cov tsav tsheb cement tau txais nyob rau hauv qab ntawm txoj kab tsheb ciav hlau. Leveling thiab nteg tawm. Rail soj ntsuam thiab straightening, taug qab sab sauv, rail sib txuas kev sib txuas, alignment reinforcement, ntsuas ntsuas, leveling, straightening. Iav ua cov cuab yeej, cov khoom siv tus qauv ntawm txoj kev khiav yuav tsum ua raws li cov kev cai thiab cov qauv ntawm TJ231-78 "Cov cuab yeej siv tshuab thiab cov cuab yeej siv tshuab kev tsim kho kev lees paub", qhov sib txawv ntawm qhov siab tshaj plaws thiab qhov qis tshaj plaws ntawm tag nrho cov hlab ntsha yog tsis ntau tshaj 10 hli, qhov offset ntawm sab laug, sab xis thiab sab sauv peb sab ntawm qhov sib koom ua ke tsis ntau tshaj 1 hli, qhov sib txawv ntawm qhov sib koom tsis siab tshaj 2 hli, qhov kev ua yuam kev yuav tsum tsis txhob siab tshaj 5 hli, qhov sib txawv ntawm qhov sib txawv Qhov siab ntawm ob qho tib si lem ntawm tib qhov ntev yuav tsum tsis txhob siab tshaj 10mm ntawm kem, thiab yuav tsum tsis txhob siab tshaj 15mm ntawm lwm qhov chaw.
(2) Cov khoom siv zawv zawg
Kev sib cuag ntawm cov kab swb yuav tsum tiaj tus, ncaj, tsis muaj xeb, zoo heev conduction, cov khoom tsim nyog, thiab cov khoom siv nyiaj yuav tsum tau teeb tsa thaum hla kev nthuav dav ntawm lub tsev. Siv cov xim liab rau ntawm qhov chaw uas tsis yog-conductive ntawm cov khoom siv hluav taws xob xaim xaim thiab tso cov khoom siv kev nyab xeeb los yog qhov taw qhia lub teeb qhia hluav taws xob nyob rau hauv qhov kev taw qhia tsim nyog. Yog hais tias cov cuab yeej muaj kev ruaj ntseg swb cov hlau, nws yuav tsum ncaj thiab zoo heev conductive. Yog tias cov khoom siv hluav taws xob siv hluav taws xob, cov kab xov tooj yuav tsum tau ua raws li qhov kev thov thiab cov hlua traction yuav tsum tau teem caij.
(3) Tus choj erection ntawm lub crane yog npaj los tsim
Ua ntej cov khoom siv, cov khoom siv yuav tsum tau muab tshem tawm ua ke nrog cov neeg sawv cev ntawm cov khoom siv uas tau tso siab rau thiab cov khoom tsim khoom. Raws li qhov random packing, xyuas thiab xyuas seb cov khoom xa tuaj puas yog raws li cov naj npawb ntawm cov npe hauv cov ntawv ntim khoom thiab seb cov ntaub ntawv random puas tiav. Tom qab kuaj xyuas, cov ntaub ntawv yuav tsum tau ua thiab kos npe los ntawm cov neeg sawv cev ntawm peb tog ntawm qhov chaw. Thaum sib sau ua ke thiab txhim kho tus choj, tag nrho cov neeg ua haujlwm tsim kho kev tsim kho tau nruj me ntsis raws li cov cai tswj kev nyab xeeb ntawm txhua hom kev ua haujlwm, thiab nws raug txwv tsis pub ua haujlwm ua txhaum cai.
Thaum sib sau ua ke lub crane, tus choj yuav tsum tau muab tso rau ntawm lub cushion raws li kev taw qhia ua haujlwm, tom qab kho qhov ruaj khov, thiab tom qab ntawd sib sau cov kab hluav taws xob kawg, qhov sib txawv ntawm kab pheeb ces kaum yuav tsum tsis txhob siab tshaj 5 hli, qhov ntev yuav tsum tsis txhob siab tshaj 3 hli, thiab tom qab ua tiav tag nrho cov kev cai, lub tshuab hluav taws xob hoist yuav tsum tau sib sau ua ke, lub tsheb khiav qhov sib txawv yuav tsum tsis txhob siab tshaj 5 hli, thiab chav tswj kev sib dhos zaum kawg.
(4) Cov khoom siv hluav taws xob
Ua ntej cov cuab yeej yuav tsum tau nkag siab tshwj xeeb rau cov hluav taws xob schematic daim duab, daim duab faib, hluav taws xob kos duab thiab cov ntaub ntawv tseem ceeb, nkag siab txog lub hauv paus ntsiab lus ntawm kev ua haujlwm thiab cov txiaj ntsig ntawm txhua yam. Txhawm rau kom raug cov cuab yeej siv thiab agile ua cov khoom siv hauv cov txheej txheem ntawm cov lus nug. Xyuas qhov txheeb ze ntawm txhua qhov hluav taws xob tivthaiv thiab lub cev muaj zog yuav tsum tsis txhob tsawg dua {{0}}.8 megohm. Nyob rau hauv ib qho chaw ntub dej yuav tsum tsis txhob tsawg dua 0.4 megohm, xyuas seb cov kab puas muaj tseeb, thiab txiav txim siab tias tsis muaj qhov yuam kev me ntsis ua ntej lub zog ntsuas hluav taws xob. Thaum lub sij hawm sim khiav, xyuas seb cov kev taw qhia khiav yog ib txwm muaj, seb qhov kev hloov pauv stroke puas ua tau raws li qhov xav tau, thiab seb lub hwj chim sab sauv thiab sab qis yog qhov muaj kev nyab xeeb thiab txhim khu kev qha. Txhua yam khoom siv kev nyab xeeb yuav tsum muaj kev nyab xeeb, ruaj ntseg thiab tsim nyog ua ntej hoisting. Nyob rau hauv cov txheej txheem hoisting, nruj me ntsis raws li txoj cai kev nyab xeeb kev khiav hauj lwm, thiab txwv tsis pub ua hauj lwm txhaum cai.
Thib tsib, lub crane them lub plhaub, lub raj xaim, thiab lwm yam, yuav tsum tau ua kom ruaj khov, lub crane khiav thiab cov av tiv thaiv ntawm ib qho taw tes ntawm lub crane yuav tsum tsis txhob ntau tshaj 4 ohms. Qhov rov qab grounding kuj tsis ntau dua 10 ohms. Lub rwb thaiv tsev tiv thaiv ntawm lub ntsiab Circuit Court thiab tswj Circuit Court rau hauv av tsis tsawg tshaj li 0.8 megohm.
6. Tom qab lub crane tau tsim nyog rau kev sim ua haujlwm, nws yog ib qho tsim nyog yuav tsum tau ua qhov kev sim tsis muaj kev thauj khoom, kev sim ua haujlwm zoo li qub thiab kev sim ua haujlwm dynamic. Tom qab dhau qhov kev tshuaj xyuas tus kheej, sau cov lus ua tiav ua tib zoo, qhia rau tog A, npaj cov tuam haujlwm cuam tshuam los lees txais, thiab xa mus siv tom qab dhau qhov kev tshuaj ntsuam xyuas.
Ob peb lub ntsiab lus thiab txoj hauv kev kom raug yuav tsum tau them sai sai rau thaum teeb tsa ib lub nqaj crane
1, lub mast yog teem nyob rau hauv nruab nrab ntawm lub ntsiab beam ntawm lub crane, thiab me ntsis nyob ze rau sab ntawm lub hnyav lub ntsiab beam, thiaj li hais tias lub lifting crane yuav tsis qaij, thiab hluav taws xob hoist yog ruaj khov khi rau lub ntsiab beam. tib lub sijhawm.
2, kev nqa yuav tsum tau khaws cia ruaj khov, tsis tuaj yeem ua viav vias ywj pheej, txhawm rau kom cov neeg tuaj yeem tswj tau, tuaj yeem khi rau ntawm ob qhov kawg ntawm txoj hlua crane.
3, siv lub hoist thiab mast, hlua rau hauv lub qhov nqa nqa.
4. Nqa lub crane mus rau qhov siab uas tsim nyog, txhim kho chav tswj nrog bolts ntawm lub rooj sib txuas thiab lub rooj sib txuas, thiab tom qab ntawd txuas lub rooj sib txuas ntawm lub ntsiab nqaj thiab nqaj raws li cov duab kos.
5, nqa lub crane kom dhau txoj kev khiav, rub txoj hlua mus rau twist lub crane, thiab maj mam poob kom lub crane log zawj ua ke nrog txoj kev khiav qeeb.
Cov saum toj no yog ib qho beam crane erection yuav tsum tau them sai sai rau cov ntsiab lus thiab txoj kev raug, Kuv vam tias feem coob ntawm cov neeg siv tuaj yeem teeb tsa raws li txoj kev no thaum siv, txhawm rau txhim kho kev nyab xeeb ntawm kev ua haujlwm crane.
