Cov chaw ua haujlwm loj taub ntug dej, tus txiv neej muaj zog ntawm kev ua haujlwm ntawm ntug dej, tso saib nws cov kev txawj?

Nyob rau hauv lub zoo kawg marine engineering, cov neeg tseem ceeb ntawm lubMarine Cranetsev neeg - tusMarine Platform Cranetuaj yeem hu ua "hiav txwv muaj zog." Txawm hais tias nws yog qhov hloov chaw ntawm cov khoom siv roj av, cov hoisting ntawm cov khoom siv hluav taws xob hauv nkoj, lossis cov khoom siv no tuaj yeem ua tiav txoj haujlwm ua tiav nrog nws cov kev ua tau zoo. Kev noj ntau dua hluav taws xob hydraulic crane ua piv txwv, nws cov txheej txheem ua haujlwm tuaj yeem faib ua peb lub zog thiab kev ua haujlwm.

1. Cov khoom siv xaiv thiab tshuaj ntsuam "kev kuaj mob lub cev"
Ib qho tsim nyogOffshore platform lossisLawj CraneYog qhov zoo nyob ntawm qhov hnyav cargo (xws li los ntawm ob peb tons rau ntau pua), qhov loj me, thiab qhov siab ua haujlwm. Piv txwv li, cov nkoj nrog cov kab ke compact rau lawj

▶ Cov ntsiab lus soj ntsuam:

1. Seb cov tshuab tshuab (jib, hlua hlua dig, nuv) hnav
2. Kuaj seb cov kab ke hydraulic (tub ntxhais ntawmHluav Taws Xob Hydraulic Crane) Muaj roj to thiab seb puas muaj nuj nqis ua tau raws li tus qauv
3. Seb lub tshuab hluav taws xob thiab tswj cov kab ke (suav nrog kev tawm tsam sab nraud thiab cov khoom siv thauj khoom) tau khiav

2. Kev sojntsuam ib puag ncig thiab Kev Nyab Xeeb Kev Xa Khoom

1. Sau cov ntaub ntawv tiag tiag ntawm cov haujlwm ua haujlwm: Dej tob, tidal nrawm, xav tau tsawg dua lossis sib npaug ntawm kev ua haujlwm nyab xeeb ntawm lubMarine Crane, feem ntau yog qis dua qib 12 typhoon), yoj qhov siab, thiab lwm yam.
2. Npaj txoj kev ua haujlwm: Zam kev tua cov pa roj (xws li cov pa hluav taws xob thiab xaim xaim), thiab khij lub lawj ntsaws cov khoom txwv
3. Cov neeg ua haujlwm npaj: Cov neeg ua haujlwm yuav tsum muaj ntawv pov thawj, paub txog "Ntug dej CraneCov Txheej Txheem Kev Nyab Xeeb, "Thiab Nruab Nrog Cov Hnab looj tes cawm siav, thiab lwm yam khoom siv tiv thaiv

1. Diav Lifting: Kauj Ruam Cov kauj ruam los ntawm "mus khov kho" rau "Lifting"

1. Kev Txuas Txuas: Siv cov xa khoom tshwj xeeb (xws li ntim cov khaub ncaws tshwj xeeb (ua kom sib txuas nrog cov neeg thauj khoom sib cav sib ceg yog tsawg dua 5% (zam tilting)
2. Meback Lifting: Lub chaw nres tsheb ua haujlwm Hydraulic Lub Torque Limiter cov ntaub ntawv yog soj ntsuam tib lub sijhawm, thiab overloading yog nruj me ntsis txwv (muaj sib npaug rau 1.5 zaug tus ntaus nqi)
3. Anti-Sway Tswj: Pab kom cov tuam txhab ntse yuav ua rau lub nkoj tsis sib xws (ruaj khov rau 3 degree thiab lub suab nrov tsawg dua lossis sib npaug

2. Txheeb xyuas: "Peb-qhov seev cev" ntawm lub lawj

1. Kev ua haujlwm sib hloov: 360 degree ua tiav kev sib hloov mechanism rotates ntawm kev ceev ntawm 5 degree \/ s kom tsis txhob muaj drilling rigs thiab radar antennas)
2. Kuj muaj cov kev hloov kho tsis tau zoo: los ntawm cov hydraulic kheej kheej lub tog raj kheej botfinder, nws tuaj yeem ua tiav millimeter-theem kev ua haujlwm (yuam kev tsawg dua lossis sib npaug ntawm 2cm)
3. Kev thauj khoom qis dua: Thaum nce lub hom phiaj, hloov mus rau "hom micro-motion hom," tus neeg teb xov tooj tuaj yeem tswj tau cov cuab yeej siv ob chav kom paub tseeb tias cov thauj khoom tau muab tso kom zoo.

3. Cov xwm txheej tshwj xeeb: "Lub neej channel" rau manned nqa
Thaum siv tus qauv muj dai dai pob tawb (cov nqi ntsuas qis dua lossis sib npaug rau 500kg, txwv rau 6 tus neeg):

1. Cov pob tawb dai khaub ncaws yuav tsum tau nruab nrog kev tshem tawm ywj pheej (ob chav hlau hlua hluav taws xob roj liab dedundant tsim)
2. Cov neeg ua haujlwm yuav tsum hnav siv tawv rau kev nyab xeeb txhua lub sijhawm thiab tswj kev sib txuas lus tiag tiag nrog covNtug dej Cranetus tsav
3. Lifting ceev yog txwv rau 0. 3m \/ s, thiab nws raug txwv tsis pub muaj cua ntau tshaj li qib 6

1. Khoom siv pib dua thiab saib xyuas tob

1. Lub cev pib dua: Qhov Boom poob rov qab mus rau 45 degree Nyab Xeeb Chaw Nres Tsheb, tus nuv nce mus rau qhov siab ntawm 2 metres los ntawm lub lawj, thiab tsis yog lub zog tseem ceeb yog txiav tawm
2. HYDRAULIC txij nkawm:Hluav Taws Xob Hydraulic Cranesyuav tsum tau kuaj cov kev huv ntawm cov roj hydraulic (particle loj dua lossis sib npaug rau NAS 1638 qib 9) thiab hloov cov ntsaws ruaj ruaj
3. Kev tshuaj xyuas cov txheej txheem: tsom rau kev tshuaj xyuas Welds (tshwj xeeb yog cov khawm khawm ntawm lub boom) thiab cov ntsia hlau nruj (torque yuav tsum ncav cuag ntau dua 95% ntawm tus qauv tsim)

2. Cov ntaub ntawv kaw cia thiab kev ua tau ntau yam ntxiv

1. Sau rau hauvNtug dej CraneTxoj Haujlwm Xov Xwm sau cia:

Insnument Lub sijhawm ua haujlwm, tus naj npawb ntawm nqa, cumulative load

✅ Khoom txawv (xws li suab nrov tsis zoo, txwv lub tswb)

Paint Ib puag ncig tej kev tsis sib xws xws li hloov pauv ntawm cua nrawm, dej ntws txawv, thiab lwm yam)

2. Txheeb xyuas cov ntaub ntawv tsis tu ncua thiab ua haujlwm cov txheej txheem ua haujlwm (xws li hloov kho lub sijhawm nyob hauv qab ntawm cov tides) los muab cov ntaub ntawv rau cov ntaub ntawv zoo sib xwsLawj Crane/Offshore platform Crane.
