Ob peb xyoos dhau los kuv tau hnov tias ib tug kws tshaj lij xav npaj cov khoom lag luam ntawm "cov nplai crane dynamic", tab sis rau qee yam nws tsis tau qhia.Nyob rau hauv qhov tseeb, raws li daim ntawv thov ntawm lub crane scale yuav tsuas yog positioned raws li ib tug nonautomatic scale, muaj ntau yam teeb meem tsis tau piav qhia meej.
Ib tug dynamiccrane nplaiyuav tsum yog lub crane nplai uas hnyav thaum lub thauj khoom nqa thiab txav mus rau tib lub sijhawm thaum lub sijhawm nqa.Nws yog qhov nyuaj rau kev paub qhov txawv ntawm qhov hnyav hnyav thiab qhov hnyav li qub yog tias lawv tsuas yog txhais tau li ntawd.Vim hais tias "dynamic hnyav" txhais tau hais tias: lub load tau hnyav thiab cov khoom nqa tau muaj kev sib txheeb ze, thaum lub crane nplai rau qhov hnyav nruab nrab ntawm ob qhov tsis muaj txheeb ze, tsuas yog nyob rau ntau lub sijhawm siv crane, vim cov khoom dai ntawm lawv. tus kheej original.Txij li thaum cov khoom yuav tsum tau hnyav yog tsis tshua muaj nyob rau lub sij hawm luv luv, txawm tias tus nqi nyeem ntawv, nws tseem me ntsis txawv ntawm tus nqi ntawm so.
Crane nplai muaj xws li nuv nplai, crane-hom crane nplai, gantry (bridge) crane nplai.Thiab crane hom crane scale yog roughly hnyav trolley hom, hlau hlua reel hnyav hom, ruaj pulley hnyav hom thiab hais txog.Hook lub taub hau crane nplai yog lub xov tooj ntawm tes ntsia ncaj qha rau ntawm tus nuv lub taub hau ntawm cov khoom nqa nqa, daim ntawv qauv ntawm crane nplai, feem ntau ntawm kev sib xyaw ua ke ntawm ntau hom load hlwb.Gantry (choj) crane scales, feem ntau yog ntawm cov hlau hlua reel hnyav hom.
Thaum peb saib cov khoom ntsuas xws li crane nplai ib leeg, nws tuaj yeem txhais tau tias yog "tsis siv neeg ntsuas".Txawm li cas los xij, yog tias peb saib tag nrho cov kev nqa nqa, txawm tias nws yog ntug hiav txwv choj crane lossis gantry system hauv qhov chaw nres nkoj, lossis ib qho nyiaj siv ua haujlwm crane hauv kev lag luam lossis kev lag luam mining, tag nrho cov ntawm lawv yog sib cais los ntawm txoj hlua txuas ntev, thiab Tag nrho cov ntawm lawv tau soj ntsuam cov khoom hnyav thaum lub sij hawm nqa thiab txav cov txheej txheem hnyav tus nqi.Nws yog vim txoj kev ntsuas no thiab cov hlua hlau uas ua rau ob qho teeb meem rau kev siv cov nplai crane:
(1) Nyob rau hauv cov txheej txheem nqa, nyob rau hauv qhov kev txiav txim ntawm cov cuab yeej lifting quab yuam thiab lub ntiajteb txawj nqus ntawm cov khoom, cov hlau hlua ncua lub crane nplai yuav inevitably stretch thiab contraction ntawm lub zog, thiab tej zaum cov lifting khoom suspending lub crane nplai kuj tseem. tshee hnyo.Nws yog nyob rau hauv no elastic nyhuv, lub crane nplai tsis tuaj yeem ncav cuag qhov txiaj ntsig ntawm qhov hnyav ntawm lub sijhawm.
(2) Feem ntau, cov nplai crane siv sab nraum zoov, yuav raug cuam tshuam los ntawm ib puag ncig, tshwj xeeb tshaj yog cov crane nplai siv rau ntawm qhov chaw nres nkoj, los ntawm cua yuav tsim oscillation ntawm crane nplai yuav ntau dua los txhawb kev tshee ntawm cov hlau. hlua, tab sis kuj cuam tshuam qhov kev cuam tshuam ntawm tsis nyob rau hauv lub sij hawm kom tau txais qhov hnyav ntawm cov yam ntxwv.
