Kev tiv thaiv overload ntawm tes saw hoist ua haujlwm li cas?
Tus tsim ntawmtes saw hoistoverload tiv thaiv ntaus ntawv yog xyuas kom meej tias thaum lub load tshaj lub load peev xwm ntawm tes saw hoist thaum lub sij hawm lifting lub lag luam, ceeb toom yuav muab tau nyob rau hauv lub sij hawm thiab lub lifting yuav tsum nres, yog li tiv thaiv kev ruaj ntseg ntawm tus neeg teb xov tooj thiab cov khoom siv. Cov hauv qab no yog cov txheej txheem tshwj xeeb ntawm kev tiv thaiv overload ntawm tes saw hoist:

1. Kev ceeb toom ntxov thiab txwv cov txheej txheem
Cov cuab yeej tiv thaiv overload feem ntau suav nrog ob txoj haujlwm: ceeb toom ntxov thiab txwv. Thaum lub load nce mus txog qhov ntsuas lub peev xwm ntawm tes saw hoist, cov txheej txheem ceeb toom ntxov yuav tshaj tawm cov lus ceeb toom, xws li lub suab lossis lub teeb ceeb toom, ceeb toom rau tus neeg teb xov tooj kom xyuam xim rau lub nra. Yog hais tias lub load tshaj qhov teeb meem kev nyab xeeb, qhov txwv mechanism yuav qhib kom tsis txhob muaj tes saw hoist mus ua hauj lwm.

2. Elastic deformation thiab kho mechanism
Lub tes saw hoist overload txwv cov cuab yeej ua ntej teeb tsa kev nyab xeeb los ntawm kev teeb tsa qhov siab tshaj plaws elastic deformation ntawm thawj lub caij nplooj ntoos hlav. Thaum lub load tshaj qhov teeb tsa tus nqi, tus pas nrig txav tau txav tawm ntawm qhov los ntawm qhov, thiab tom qab ntawd tus pas nrig txav tau txav mus rau hauv cov iav hauv tes saw hoist, ua rau nws tsis tuaj yeem ua haujlwm li qub.

3. Eccentric bracket thiab thawb hloov
Qee cov khoom siv tiv thaiv overload siv lub zog qis ntawm lub eccentric bracket los nyem lub zog dhau lub laub hloov kom ua tiav qhov kev ceeb toom ntxov. Txawm li cas los xij, qhov kev tsim no yuav ua rau lub overload thawb hloov los ntawm lwm yam khoom ntog thaum lub eccentric bracket tsis poob rau hauv txoj hauj lwm overload, ua rau tsis tshua muaj kev ceeb toom ntxov.

4. Jammed iav mechanism
Txhawm rau txhim kho qhov tseeb, qee cov tes saw hoist overload txwv cov cuab yeej siv cov cuab yeej hloov kho kom tsav lub pas nrig txav mus rau cov iav hauv tes saw hoist. Cov txheej txheem no siv qhov kev ncua deb ntawm cov kab txav txav mus los los txiav txim siab qhov siab tshaj plaws load peev xwm, ua tiav kev txwv tsis pub dhau, siab rhiab heev, thiab qhov yuam kev tsawg.

5. Cov qauv kev tiv thaiv
Cov qauv ntawm tes saw hoist overload tiv thaiv ntaus ntawv yuav muaj xws li ib lub thawv ruaj khov, ib qho kev sib txuas ruaj khov, ib kem txav tau, lub phaj txwv, thawj lub caij nplooj ntoos hlav, lub pas nrig txav, thiab kev hloov kho. Cov khoom no ua haujlwm ua ke los xyuas kom meej tias cov saw hoist nres ua haujlwm thaum muaj kev sib tsoo, tiv thaiv kev sib tsoo

6. Txhim kho kev nyab xeeb kev ua haujlwm
Kev taw qhia ntawm cov khoom siv tiv thaiv overload tau txhim kho kev nyab xeeb ntawm cov saw hoists. Lawv tuaj yeem tsis tsuas yog ceeb toom ntawm overloading tej yam kev mob, tab sis kuj nres lub lag luam ntawm lub saw hoist thaum tsim nyog kom tsis txhob muaj kev tsis ua hauj lwm thiab kev huam yuaj tshwm sim los ntawm overload.

Hauv cov ntsiab lus, kev tiv thaiv overload ntawm cov saw hoist saib thiab txwv kev thauj khoom los ntawm cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob los xyuas kom muaj kev nyab xeeb. Kev tsim thiab kev siv ntawm cov cuab yeej no qhia txog kev nce qib thiab kev tsim kho tshiab hauv kev nyab xeeb ntawm cov cuab yeej nqa niaj hnub.
