Classification thiab Cheebtsam ntawm cranes
Lub crane yog cov cuab yeej siv kho tshuab uas ua haujlwm tsis tu ncua thiab rov ua haujlwm rau vertically nqa thiab horizontally txav cov khoom hnyav dai rau ntawm hooks lossis lwm yam khoom nqa nqa nyob rau hauv ib qho chaw spatial.
(1) Cov cranes tuaj yeem raug cais raws li lawv cov qauv, suav nrog gantry cranes, boom cranes, thiab hlua cranes. Choj cranes tuaj yeem muab faib ua subcategories xws li choj cranes, gantry cranes, thiab thauj khoom thiab thauj cov choj. Boom cranes tuaj yeem muab faib ua ntau pawg xws li ntauwd cranes, gantry cranes, mobile cranes, cantilever cranes, thiab mast cranes. Peb feem ntau pom choj cranes, ntauwd cranes, thiab mobile cranes hauv peb lub neej txhua hnub.
Ntau hom kev tsim kho cranes feem ntau yog tsim los ntawm plaub ntu: kev ua haujlwm mechanism, cov qauv hlau, cov cuab yeej hluav taws xob, thiab kev tswj hwm. Lub tshuab ua haujlwm ntawm lub crane suav nrog plaub qhov tseem ceeb: nqa lub tshuab, slewing mechanism, slewing mechanism, thiab taug kev mechanism. Lub lifting qauv muaj xws li ib tug prime mover, ib tug nruas, ib tug hlau hlua, ib tug pulley system, thiab ib tug nuv. Muaj cov tshuab thiab hydraulic kis tau tus mob rau kev nqa. Crane slewing yog hais txog kev hloov qhov kev ncua deb ntawm qhov nruab nrab ntawm tus nuv thiab lub axis ntawm lub crane qhov chaw rotation. Daim ntawv ntawm qhov sib txawv amplitude mechanism nyob ntawm hom boom ntawm mobile crane. Rau truss cranes nrog ntev ntev, lub slewing mechanism txais ib txoj hlua hlau slewing mechanism. Lub slewing mechanism ntawm lub mobile crane nrog telescopic boom txais ib lub hydraulic kheej kheej slewing mechanism. Lub rotary mechanism muaj xws li ib tug rotary tsav ntaus ntawv thiab ib tug teb bearing. Lub slewing bearing ntaus ntawv ntawm mobile cranes feem ntau yog siv dov bearing hom. Txoj kev taug kev ntawm lub xov tooj ntawm tes crane yog lub chassis ntawm crane, thaum lub log crane siv lub chassis universal lossis tshwj xeeb tsheb, lossis lub chassis tshwj xeeb tsim rau crane. Lub crawler crane siv lub crawler chassis. Txoj kev taug kev ntawm ntauwd thiab choj cranes feem ntau yog qhov tshwj xeeb tsim kev khiav haujlwm
(2) Cov qauv hlau ntawm lub crane muaj xws li lub boom, rotating platform, A-thav duab, chassis, thiab ntauwd lub cev ntawm ntauwd crane. Cov qauv hlau bears qhov hnyav ntawm crane thiab ntau yam loads thaum ua haujlwm. Lub zog, nruj, thiab ruaj khov ntawm cov qauv hlau yog peb qhov ntsuas tseem ceeb.
(3) Lub zog hluav taws xob ntawm lub xov tooj txawb crane yog lub tshuab hluav taws xob sab hauv, thaum lub zog hluav taws xob ntawm ntauwd thiab lwm hom cranes yog lub tshuab hluav taws xob.
(4) Kev tswj hwm ntawm lub crane muaj xws li cov cuab yeej tswj thiab cov cuab yeej kev nyab xeeb. Lub kaw lus tswj tau nruab nrog clutches, nres, thiab ntau yam tswj li qub hauv hydraulic kis ntawm lub nres.
