T Cov txheej txheem tsim khoom rau lub thoob thoob gantry crane yog ib qho kev ua haujlwm uas ua ke nrog cov hlau hnyav, kev sib dhos, thiab hluav taws xob sib xyaw. Nws yog feem ntau nqa tawm nyob rau hauv ib tug tshwj xeeb hnyav industrial Rhiav.

Ntawm no yog cov ncauj lus kom ntxaws txog cov txheej txheem tsim khoom.

 

Theem 1: Tsim & Engineering

Qhov no yog lub hauv paus theem uas lub crane yog xeeb raws li cov neeg siv khoom xav tau.

Customer Specifications:Cov txheej txheem pib nrog cov neeg siv khoom kom ntxaws: nqa lub peev xwm (piv txwv li, 25 tons), ncua, nqa qhov siab, lub voj voog ua haujlwm (piv txwv li, Chav A4 rau kev siv nruab nrab), thiab cov khoom siv tshwj xeeb yuav tsum tau ua (xws li, thee, seem hlau).

Tus Qauv Tsim:Cov kws tsim khoom siv CAD (Computer-Aided Design) software los tsim cov duab kos kom ntxaws ntawm txhua yam khoom siv-bridge girders, ceg, trolley thav duab. Lawv ua Finite Element Analysis (FEA) kom simulate kev ntxhov siab thiab ua kom muaj kev ncaj ncees.

Mechanical Design:Tsim cov tshuab hoist, trolley tsav, kawg tsheb sib dhos, thiab xaiv cov khoom siv xws li lub log, bearings, lub zog, thiab cov hlua hlau.

Hluav taws xob tsim:Tsim cov schematics rau lub hwj chim mov, lub cev muaj zog tswj, tsav systems, thiab tus neeg teb xov tooj interfaces (cabin los yog pendant).

Daim Ntawv Pov Thawj (BOM):Ib daim ntawv teev tag nrho cov ntaub ntawv raw (steel daim hlau, profiles) thiab cov khoom yuav khoom (lub cev muaj zog, brakes, sensors) yog tsim.

 

Theem 2: Steel Fabrication

Qhov no yog thawj qhov kev cob qhia uas cov hlau nyoos tau hloov mus rau hauv cov khoom siv crane.

Kev npaj khoom siv:Cov phaj hlau thiab ntu (xws li kuv- kab teeb) raug txiav kom loj siv CNC (Computer Numerical Control) plasma cutters lossis laser cutters rau qhov tseeb.

Sub-Assembly Fabrication:Cov khoom me me yog tsim. Piv txwv li, cov tsheb thauj khoom kawg yog tsim los ntawm vuam vaj tse rau lub log thiab axles.

Major Assembly Fabrication:

Girder Fabrication:Lub ntsiab choj girders yog tsim. Rau ob chav girder cranes, qhov no suav nrog tsim ob lub thawv zoo tib yam los ntawm vuam steel daim hlau. Strongbacks thiab diaphragms yog welded sab hauv los tiv thaiv buckling.

Leg Fabrication:Cov ceg ntoo yog welded los ntawm cov hlau phaj, tsim cov kab muaj zog uas yuav txhawb nqa cov girders.

Machining:Qhov chaw tseem ceeb, xws li cov ntaub qhwv qhov rooj zaum ntawm ob txhais ceg los yog cov lem rau lub log tsheb, yog machined los xyuas kom meej zoo meej flatness thiab sib dhos.

 

Kauj Ruam 3: Component Assembly

Mechanical sub-semblies muab tso ua ke.

Hoist Assembly:Lub hoist unit tau sib sau ua ke, suav nrog kev txhim kho lub tshuab hluav taws xob, lub zog, nres, thiab lub nruas rau ntawm cov ncej nruj. Cov hlua hlau yog spooled rau ntawm lub nruas.

End Truck Assembly:Log, qag, bearings, thiab tsav motors raug ntsia rau hauv lub tsheb kawg vaj tse.

 

Kauj Ruam 4: Kev Kho Hniav & Painting

Cov kauj ruam tseem ceeb no tiv thaiv lub crane los ntawm kev xeb, tshwj xeeb tshaj yog vim nws feem ntau ua haujlwm hauv qhov chaw hnyav xws li cov chaw nres nkoj.

Kev npaj nto:Tag nrho cov khoom siv hlau raug tua- blasted kom tshem tawm xeb, zeb nplai, thiab cov kab mob, tsim kom huv si, ntxhib nto rau xim adhesion.

Priming:Ib qho xeb-inhibitive primer yog siv tam sim tom qab blasting.

Kev kos duab:Ntau lub tsho loj ntawm siab - cov xim ua haujlwm (xws li epoxy, polyurethane) yog siv rau cov thicknesses. Xim coding feem ntau yog siv rau kev nyab xeeb thiab zoo nkauj.

 

Theem 5: Kev sib koom ua ke ntawm hluav taws xob

Cabin Wiring:Tus neeg teb xov tooj lub tsev yog nruab nrog cov tswj vaj huam sib luag, joysticks, thiab cov khoom siv kev nyab xeeb.

Crane Wiring:Cov vaj huam sib luag hluav taws xob, cov tsav tsheb sib txawv (VFDs rau kev tswj kom zoo), thiab cov kab hluav taws xob festoon tau nruab rau ntawm tus choj thiab lub trolley.

Lub cev muaj zog Installation:Tag nrho cov tsav motors (choj, trolley, hoist) yog txuas nrog lub tshuab hluav taws xob.

Sensor Installation:Txwv cov keyboards, tiv thaiv- lub tshuab kev sib tsoo, thiab lub sijhawm ntsuas lub sijhawm (LMI) raug teeb tsa thiab xaim.

 

Kauj Ruam 6: Rhiav Kev Sib Tham Sib Tham

Ua ntej disassembly rau cov khoom xa tuaj, lub crane feem ntau yog ib feem los yog tag nrho sib sau ua ke nyob rau hauv lub rhiav.

Dimensional Verification:Qhov "dry haum" no ua kom txhua qhov sib xyaw ua ke kom raug- tias ob txhais ceg yog perpendicular, lub girder yog theem, thiab lub trolley khiav zoo.

Kev kuaj ua haujlwm:Cov haujlwm tseem ceeb ntawm lub cev muaj zog raug kuaj yam tsis muaj kev thauj khoom los kuaj xyuas kev sib hloov thiab kev tswj cov lus teb.

 

Theem 7: Dismantling, ntim, thiab xa khoom

Dismantling:Lub crane yog ua tib zoo disassembled rau hauv kev thauj mus los modules (girders, ceg, trolley, thiab lwm yam).

Ntim:Cov khoom xyaw raug ntim los tiv thaiv kev puas tsuaj thaum caij tsheb npav. Cov ntsiab lus nqa tau pom meej meej.

Kev xa khoom xa tuaj:Txhua qhov chaw raug xa mus rau cov neeg siv khoom qhov chaw, nrog rau cov ncauj lus kom ntxaws sib dhos thiab cov ntawv qhia.

 

Kauj Ruam 8: Ntawm -Qhov Chaw Nruab & Kev Ua Haujlwm

Cov theem kawg, feem ntau saib xyuas los ntawm cov chaw tsim khoom engineers.

Kev npaj qhov chaw:Cov kev khiav tsheb ciav hlau raug teeb tsa thiab ua kom tiav los ntawm tus neeg siv khoom lossis tus neeg cog lus.

Erection:Siv mobile cranes, cov khoom sib sau ua ke ntawm txoj kev khiav.

Kev Ua Haujlwm:Nov yog qhov kawg validation:

Alignment Checks:Txheeb xyuas qhov kev sib tw ntawm crane nrog txoj kev khiav.

Load Test:Ua ob qhov kev ntsuam xyuas tseem ceeb:

Static Load Test:Kev nqa lub nra 25% ntau dua li qhov ntsuas muaj peev xwm los ntsuas cov qauv kev ncaj ncees.

Dynamic Load Test:Nqa lub peev xwm ntsuas tag nrho thiab khiav nws los ntawm txhua qhov kev taw qhia los ntsuas kev ua tau zoo raws li -cov xwm txheej hauv ntiaj teb.

Kev Tshawb Fawb Kev Nyab Xeeb:Xyuas kom tseeb tias txhua qhov kev txwv hloov pauv, nres, thiab nres thaum muaj xwm txheej ceev ua haujlwm raug.

Kev cob qhia neeg ua haujlwm:Cov chaw tsim khoom pab pawg cob qhia cov neeg siv khoom siv ntawm kev nyab xeeb thiab siv tau zoo.

Rhiav saib:

Lub tuam txhab tau teeb tsa cov cuab yeej ntse tswj kev tswj hwm lub platform, thiab tau teeb tsa 310 teeb (teev) ntawm kev tuav thiab vuam robots. Tom qab ua tiav ntawm txoj kev npaj, yuav muaj ntau tshaj 500 teeb (sets), thiab cov khoom siv sib txuas sib txuas yuav ncav cuag 95% . 32 cov kab vuam tau muab tso rau hauv kev siv, 50 tau npaj los nruab, thiab automation tus nqi ntawm tag nrho cov khoom kab tau mus txog 85%.
