Koj puas paub tias cranes ua haujlwm li cas?
1. Tsav Tsheb
Cov cuab yeej tsav tsheb yog siv los tsav cov khoom siv hluav taws xob ntawm lub tshuab ua haujlwm.
Cov khoom siv tsav tsheb feem ntau suav nrog hluav taws xob tsav, lub tshuab hluav taws xob sab hauv combustion thiab tib neeg tsav.
Lub zog hluav taws xob yog lub zog huv thiab kev lag luam. Hluav taws xob tsav yog hom tsav tseem ceeb ntawm niaj hnub cranes. Yuav luag tag nrho cov tsheb ciav hlau cranes, elevators, elevators, thiab lwm yam uas ua haujlwm nyob rau hauv ib qho kev txwv siv hluav taws xob tsav.
Rau mobile cranes uas tuaj yeem txav mus ntev (xws li tsheb cranes, log tsheb cranes thiab crawler cranes), feem ntau siv cov cav tov sab hauv.
Tib neeg tsav tsheb yog tsim nyog rau qee yam khoom siv nqa lub teeb thiab me me, thiab tseem siv tau los ua pab pawg, kev tsav tsheb thaub qab thiab lub zog ib ntus rau kev sib tsoo (lossis lub xeev xwm txheej) rau qee yam khoom siv.
2. Lub Koom Haum Ua Haujlwm
Lub tshuab ua haujlwm muaj xws li: hoisting mechanism, khiav mechanism, luffing mechanism thiab rotating mechanism, uas yog hu ua plaub loj mechanisms ntawm crane.
1) Lub tshuab hoisting yog lub tshuab siv los paub txog kev nqa cov ntaub ntawv ntsug, thiab yog ib qho tseem ceeb ntawm cov crane, yog li nws yog qhov tseem ceeb tshaj plaws thiab yooj yim mechanism ntawm crane.
2) Lub tshuab ua haujlwm yog lub tshuab ua kom paub txog cov khoom siv kab rov tav tuav los ntawm kev ua haujlwm ntawm crane lossis trolley. Nws tuaj yeem muab faib ua kev khiav haujlwm tsis muaj kev khiav haujlwm thiab khiav haujlwm, thiab tuaj yeem muab faib ua tus kheej-propelled thiab traction raws li nws txoj kev tsav tsheb.
3) Lub tshuab luffing yog ib qho kev ua haujlwm tshwj xeeb ntawm jib crane. Lub luffing mechanism hloov qhov chaw ua haujlwm los ntawm kev hloov qhov ntev thiab qhov siab ntawm lub boom.
4) Lub rotating mechanism yog ua kom lub jib tig ib ncig ntawm lub ntsug axis ntawm lub crane txav cov ntaub ntawv nyob rau hauv lub annular qhov chaw.
Lub crane ua tiav lub hom phiaj ntawm kev txav cov ntaub ntawv los ntawm ib tus neeg txav ntawm ib qho kev ua haujlwm lossis kev sib koom ua ke ntawm ntau lub tshuab.
3. Rov qab ntaus ntawv
Lub tshuab nqa khoom yog ib qho khoom siv uas txuas cov khoom siv nrog lub crane rau cov khoom nqa los ntawm kev nqa, tuav, nqus, clamping, tuav lossis lwm txoj kev.
Raws li qhov sib txawv, cov duab thiab qhov ntau thiab tsawg ntawm cov ntaub ntawv yuav tsum tau hoisted, ntau hom khoom tuaj tos yog siv.
Piv txwv li, hooks thiab rings feem ntau yog siv rau cov khoom tiav; lob thoob thiab hoppers feem ntau yog siv rau cov ntaub ntawv loj (xws li nplej, ore, thiab lwm yam); cov raj thiab cov tank yog siv rau cov ntaub ntawv ua kua. Kuj tseem muaj cov khoom siv tshwj xeeb rau cov khoom siv tshwj xeeb, xws li nqa cov kab hluav taws xob rau kev nqa cov khoom siv ntev, nqa cov khoom siv hluav taws xob rau kev nqa cov khoom siv hlau nplaum, rotating hooks tshwj xeeb yog siv rau metallurgy thiab lwm lub tuam tsev, nrog rau cov ntsia hlau tawm thiab lub thoob lub log. Pick-up li xws li unloading, thiab thawv-specific spreaders, thiab lwm yam.
Lub tshuab nqa khoom tsim nyog tuaj yeem txo qis kev siv zog ntawm cov neeg ua haujlwm thiab txhim kho kev ua haujlwm zoo. Tiv thaiv cov khoom dai kom tsis txhob ntog, ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov khoom dai ntawm kev puas tsuaj yog qhov tseem ceeb rau kev nyab xeeb ntawm cov cuab yeej fetching.
4. Cov qauv hlau
Cov qauv hlau yog ua los ntawm cov hlau dov nrog cov ntaub ntawv hlau (xws li lub kaum sab xis steel, channel steel, I-beam, steel yeeb nkab, thiab lwm yam.) Cov qauv ntawm tus kheej qhov hnyav thiab load-bearing steel qauv.
Qhov hnyav ntawm cov qauv hlau suav txog li 40 feem pua rau 70 feem pua ntawm qhov hnyav ntawm lub tshuab tag nrho, thiab nws tuaj yeem ncav cuag 90 feem pua rau cov cranes hnyav; nws cov nqi them rau ntau tshaj 30 feem pua ntawm cov nqi ntawm tag nrho cov tshuab.
Raws li nws cov qauv, cov qauv hlau tuaj yeem muab faib ua ob hom: cov khoom hauv plab (ua los ntawm steel phaj, tseem hu ua lub thawv qauv) thiab hom lattice (feem ntau yog ua los ntawm cov hlau seem, feem ntau nrog cov hauv paus ncej thiab kab laum), uas. tsim cov qauv hlau ntawm cranes. Basic load-bearing cov tswv cuab ntawm cov qauv. Cov khoom siv dag zog yooj yim no suav nrog txhua kab (axial force Cheebtsam), kab teeb (cov khoom siv flexural) thiab jibs (khoov Cheebtsam), thiab sib txawv ua ke ntawm ntau yam khoom siv cranes nrog cov haujlwm sib txawv. Complex quab yuam, hnyav hnyav, ntau consumables thiab tag nrho kev txav mus los yog cov yam ntxwv ua haujlwm ntawm cov qauv hlau ntawm crane.
Cov qauv hlau ntawm lub crane yog ib qho tseem ceeb ntawm crane. Nws yog lub cev pob txha ntawm tag nrho cov crane. Nws txuas cov khoom siv hluav taws xob thiab hluav taws xob ntawm crane mus rau hauv cov organic tag nrho, thiab dais thiab xa ntau yam kev thauj khoom ua haujlwm ntawm crane los tsim ib qho haujlwm. qhov chaw, kom cov khoom hnyav hoisted tuaj yeem thauj mus rau qhov chaw xaiv kom du.
Lub cev qhuav dej thiab kev puas tsuaj ntawm cov qauv hlau yuav ua rau muaj teeb meem loj heev lossis txawm tias muaj kev puas tsuaj loj rau lub crane.
5. Tswj System
Los ntawm cov tshuab hluav taws xob thiab hydraulic los tswj thiab tswj kev txav ntawm lub crane ntau yam mechanisms thiab tag nrho lub tshuab, ntau yam kev nqa nqa tau ua.
Kev tswj hwm thiab kev tswj hwm muaj xws li ntau yam kev tswj xyuas, cov lus qhia thiab cov khoom muaj feem cuam tshuam thiab cov kab, thiab yog qhov sib txuas ntawm tib neeg-tshuab sib tham.
Cov kev cai ntawm kev nyab xeeb ergonomics yog tsom rau ntawm no. Lub xeev ntawm cov txheej txheem yog ncaj qha ntsig txog qhov zoo, kev ua haujlwm zoo thiab kev nyab xeeb ntawm kev nqa cov haujlwm.
Qhov sib txawv tseem ceeb ntawm crane thiab lwm lub tshuab dav dav yog kev ua haujlwm ua ke ntawm cov qauv hlau loj, txav tau thiab ntau lub tsev.
Cov yam ntxwv ntawm kev ua haujlwm tsis sib xws, kev tsis sib xws ntawm kev nqa nqa, tsis sib xws ntawm lub voj voog txav ntawm txhua lub tshuab, tsis yog isochronism ntawm lub tshuab thauj khoom, thiab kev sib koom tes nrog ntau tus neeg tau nce kev ua haujlwm nyuaj thiab muaj peev xwm muaj kev nyab xeeb ntawm crane. Muaj ntau, ntau yam txaus ntshai.
Kev sib tsoo yog qhov ua rau ntau lub ntsiab lus thiab qhov tshwm sim ntawm kev sib tsoo yog qhov hnyav, yog li kev nyab xeeb ntawm cranes yog qhov tseem ceeb heev.
