Dab tsi txaus ntshai tshwm sim thaum lub sijhawm ua haujlwm ntawm txoj hlua hlau hoist?Yuav tswj tau li cas?
Cov hauv qab no yog yam tseem ceeb thiab kev tswj xyuas uas peb tau muab tso ua ke rau koj:
ib.Tom qab cov hlua hlau ntawm lub lifting winch nruas tas lawm, cov hlua hlau poob tawm thiab cov khoom hnyav ua rau neeg mob.
b.Kev siv hluav taws xob saw hoist nrog nres nres ua rau muaj kev sib tsoo
c.Cov xwm txheej tshwm sim los ntawm kev siv hluav taws xob winch hoists nrog kev ua haujlwm tsis zoo ntawm qhov nce limiter
d.Qhov qhib ntawm tus nuv ntawm cov mos lwj hluav taws xob hoist tshaj tus qauv, ua rau cov khoom hnyav plam tawm thiab ua rau tib neeg raug mob.
e.Kev siv hluav taws xob ntau dhau ua rau cov hlua hlau tawg thiab ua rau tib neeg raug mob
f.Kev siv cov hlau tawg lossis cov hlua hlau tawg ua rau cov khoom hnyav thiab cov hlua hlau raug mob.
g.Cov xwm txheej tshwm sim los ntawm kev siv cov khoom siv hluav taws xob tsis zoo
h.Lub slanted hoisting ua rau cov khoom hnyav ntaus cov neeg ua haujlwm
i.Thaum pib hluav taws xob xaim hlua hoist, tes yog nyem ntawm txoj hlua thiab cov khoom
Tswj ntsuas:
ib.Ua ntej siv, ua rov qab nqa thiab sab laug-txoj cai txav kev sim nrog cov ntsuas qhov hnyav, thiab xyuas cov khoom siv sib kis tom qab kuaj.
Txawm hais tias qhov hluav taws xob thiab qhov sib txuas yog qhov qub thiab txhim khu kev qha, nws yog txwv tsis pub nias ob lub teeb nyem tib lub sijhawm kom cov hlua hluav taws xob hoist txav mus rau qhov sib txawv ntawm lub qhov rooj khawm.
b.Thaum nqa cov khoom hnyav, nws yog nruj me ntsis txwv tsis pub tso cov hlua hlau ntawm lub nruas fais winch, thiab tsawg kawg 3 tig ntawm txoj hlua hlau yuav tsum sab laug.
C. Thaum nqa cov khoom hnyav, xyuas seb lub brakes ntawm lub tshuab hluav taws xob hoist puas muaj kev cuam tshuam, nqa cov khoom hnyav mus rau qhov siab ntawm 100mm, sawv ntsug li ob peb feeb, thiab xyuas seb lawv puas zoo li qub.
d.Ua ntej siv, xyuas seb qhov nce txwv ntawm lub cev muaj zog hoist puas rhiab.Yog hais tias nws tsis txav mus, nws yog nruj me ntsis txwv tsis pub siv, thiab nws yog nruj me ntsis txwv tsis pub siv hluav taws xob hoist yam tsis muaj qhov nce limiter.
e.Ua ntej peb theem hoist yog siv, cov tsos ntawm tus nuv ntawm cov cuab yeej yuav tsum tau kuaj xyuas.Yuav tsum tsis txhob muaj cov kab nrib pleb, qhov tsis xws luag yuav tsum tsis txhob raug kho, thiab qhov threaded, seem txaus ntshai thiab lub caj dab yuav tsum tsis txhob muaj cov yas deformation, qhov qhib yuav tsum tsis pub tshaj 10% ntawm qhov loj me, thiab qhov distortion yuav tsum tsis pub tshaj 10%.
f.Hluav taws xob saw hoist yog nruj me ntsis txwv tsis pub overloaded thiab nqa
g.Cov hlua khi nrog cov hlua tawg yog nruj me ntsis txwv tsis pub siv.Thaum pom tias cov hlau tawg hauv qhov ntev ntev> = 10%, lossis muaj lub cev deformation xws li corrosion hnyav, twisting, knotting, flattening, thiab lwm yam, steel hlau hlua yuav tsum tau hloov nyob rau hauv lub sij hawm.Raws li qhov xwm txheej ntawm cov hlua hlau, siv hlua hlua roj hauv lub sijhawm.
h.Nws yog txwv tsis pub siv lub zog hoist los nqa cov khoom hnyav diagonally.
J. Thaum hoisting, tes yuav tsum tsis txhob tuav ntawm txoj hlua thiab cov khoom, thiab cov khoom hoisting yuav tsum nruj me ntsis txwv tsis pub sib tsoo thaum nws nce.
