Cov cuab yeej tiv thaiv overload ntawm tes saw hoist tiv thaiv cov khoom hnyav los ntawm kev poob?

Kev soj ntsuam ntawm kev tiv thaiv ntawm tes saw hoist overload tiv thaiv ntaus ntawv tiv thaiv cov khoom hnyav los ntawm kev poob

I. Kev Taw Qhia
Raws li ib qho khoom siv nqa nqa,tes saw hoistsyog dav siv nyob rau hauv factories, mines, kev tsim kho qhov chaw, docks, docks, warehouses thiab lwm qhov chaw rau nruab tshuab thiab nqa khoom, tshwj xeeb tshaj yog rau qhib-cua thiab tsis muaj zog ua hauj lwm. Txawm li cas los xij, thaum siv, yog tias overload tshwm sim, nws tuaj yeem ua rau muaj qhov tshwm sim loj, xws li cov khoom siv puas tsuaj, cov khoom hnyav poob, thiab lwm yam, ua rau muaj kev phom sij rau cov neeg ua haujlwm thiab cov khoom ntiag tug. Yog li ntawd, cov cuab yeej tiv thaiv overload ntawm tes saw hoist yog qhov tseem ceeb los tiv thaiv cov khoom hnyav los ntawm kev poob.

II. Ua hauj lwm hauv paus ntsiab lus ntawm tes saw hoist
Lub tes saw hoist rub lub phau ntawv saw thiab lub tes saw log kom tig, nias qhov sib txhuam phaj ratchet thiab lub rooj zaum nres rau hauv ib lub cev thiab tig ua ke, thiab cov hniav ntev axis tig lub phaj iav, cov hniav luv axis thiab spline qhov iav. Nyob rau hauv no txoj kev, lub lifting sprocket ntsia rau ntawm lub spline qhov iav tsav lub lifting saw, li no lifting cov khoom hnyav smoothly. Lub ratchet kev sib txhuam phaj hom ib-txoj kev nres tuaj yeem nres nws tus kheej hauv kev thauj khoom. Lub ratchet koom nrog lub ratchet nyob rau hauv qhov kev txiav txim ntawm lub caij nplooj ntoos hlav, thiab lub nres ua haujlwm zoo.

3. Lub hauv paus ntsiab lus thiab kev ua haujlwm ntawm kev tiv thaiv overload
Txoj cai ua haujlwm
Cov cuab yeej tiv thaiv overload ntawm tes saw hoist feem ntau suav nrog cov txiv ntoo nres, lub tes tsho, xauv txiv ntoo, disc caij nplooj ntoos hlav, phaj siab, phaj txhuam thiab lwm yam khoom. Thaum lub sijhawm ua haujlwm ib txwm, cov saw tes tsav lub tes saw log kom tig. Lub torque ntawm tes saw log yog tsawg dua qhov kev sib txhuam ntawm kev sib txhuam phaj thiab tes saw log. Lub torque yog kis mus rau lub ncej ntev los ntawm lub nres nres, thiab tes saw log tig nrog lub nres nres thiab lub ncej ntev. Thaum ua hauj lwm nyob rau hauv overload, lub torque siv rau lub tes saw log yog ntau tshaj qhov sib txhuam quab yuam, thiab plam tshwm sim ntawm tes saw log thiab cov phaj txhuam. Lub torque tsis tuaj yeem xa mus rau cov txiv ntoo nres, yog li tsis txhob ua haujlwm dhau ntawm kev thauj khoom.
Muaj nuj nqi
Tiv thaiv overload lifting: Lub overload tiv thaiv ntaus ntawv tau prefabricated ua ntej tawm hauv lub Hoobkas. Thaum lub prefabricated overload txwv, uas yog, 1.2 npaug ntawm lub load, yog tshaj, cov cuab yeej tiv thaiv yog qhib. Lub sijhawm no, cov saw tes yuav raug kaw, nqa yuav raug thaiv, thiab tsuas yog txo qis tuaj yeem ua tau.
Tiv thaiv cov cuab yeej kev nyab xeeb: Cov cuab yeej tiv thaiv overload tuaj yeem tiv thaiv kev puas tsuaj rau cov khoom siv los ntawm overloading, xws li cov saw nqa mus txog nws qhov txwv thiab tawg, thiab lwm yam, tiv thaiv kev nyab xeeb ntawm cov cuab yeej thiab txuas ntxiv kev pab cuam lub neej ntawm cov cuab yeej.
Ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm: Cov cuab yeej tiv thaiv overload tuaj yeem tshawb xyuas lub sijhawm dhau los thiab tshaj tawm lus ceeb toom kom tus neeg teb xov tooj tau ntsuas tam sim kom tsis txhob muaj kev raug mob los ntawm cov khoom hnyav poob.

4. Cov cuab yeej tiv thaiv overload ntawm tes saw hoist puas tuaj yeem tiv thaiv cov khoom hnyav kom poob?
Mechanism tiv thaiv cov khoom hnyav los ntawm kev poob
Instant braking ntawm tus nres: Lub tes saw hoist txais lub ratchet sib txhuam phaj ib-txoj kev nres, uas tuaj yeem nres tau nyob rau hauv load. Lub ratchet koom nrog lub ratchet nyob rau hauv qhov kev txiav txim ntawm lub caij nplooj ntoos hlav kom lub nres ua haujlwm zoo. Thaum overloaded, tus nres yuav nres tam sim ntawd los tiv thaiv cov khoom hnyav poob.
Kev tiv thaiv kev tiv thaiv kev tiv thaiv kev tiv thaiv: Thaum cov khoom siv tiv thaiv overloaded overloaded, slippage tshwm sim ntawm tes saw log thiab cov phaj txhuam, thiab lub torque tsis tuaj yeem xa mus rau cov txiv ntseej nres, yog li zam kev ua haujlwm nyob rau hauv cov xwm txheej dhau. Lub sijhawm no, qhov khoom hnyav yuav tsis txuas ntxiv mus, lossis nws yuav poob.
Kev ua tau zoo hauv kev siv tswv yim
Hauv kev siv tswv yim, cov cuab yeej tiv thaiv overload ntawm tes saw hoist tuaj yeem tiv thaiv cov khoom hnyav los ntawm kev poob. Piv txwv li, tus nuv ntawm Falcon Heavy Industry National Standard HS-C tes saw hoist yog forged nrog cov ntaub ntawv zoo alloy thiab muaj kev tiv thaiv zoo tshaj. Thaum ntsib ib qho teeb meem uas qhov ntsuas load tshaj qhov ntsuas load, tus nuv yuav tsis tawg tam sim ntawd, tab sis yuav muab tus neeg teb xov tooj ceeb toom txog kev nyab xeeb nyob rau hauv daim ntawv ntawm deformation thiab dabtsi yog khoov, uas yuav ua rau muaj kev nyab xeeb ntawm kev ua haujlwm ntawm qhov chaw.

V. Kev ceev faj rau kev siv tes saw hoists
Kev tshuaj xyuas ua ntej ua haujlwm
Xyuas seb tus nuv, saw thiab ncej yog deformed los yog puas, seb tus pins ntawm qhov kawg ntawm cov saw yog ruaj khov thiab txhim khu kev qha, seb qhov kis tau tus mob hloov tau, seb lub nres nres puas ntseeg tau, thiab seb lub tes saw muaj slippage thiab saw poob.
Tshawb xyuas seb cov saw nqa nqa puas muaj kinks, thiab yog tias muaj, nws yuav tsum tau kho ua ntej siv.
Kev ua haujlwm specification
Thaum ua haujlwm ntawm tes saw hoist, thawj zaug rub lub tes saw rov qab thiab xoob cov saw nqa kom tso cai rau nws kom muaj qhov nqa tau txaus, ces maj mam nqa nws. Tom qab cov saw yog nruj, xyuas seb puas muaj qhov txawv txav ntawm txhua qhov thiab seb tus nuv puas haum. Tsuas yog tom qab lees paub tias nws yog ib txwm muaj koj tuaj yeem ua haujlwm ntxiv.
Tsis txhob rub tes saw obliquely los yog nyuaj dhau. Thaum siv nyob rau hauv ib qho inclined los yog kab rov tav kev taw qhia, lub zipper kev taw qhia yuav tsum ua raws li cov kev taw qhia sprocket kom tsis txhob saw jams thiab chain drops.
Tus naj npawb ntawm zippers yuav tsum tau txiav txim siab raws li lub peev xwm nqa ntawm lub hoist. Yog tias nws tsis tuaj yeem rub tau, xyuas seb nws puas yog overloaded, seb nws puas txuas, thiab seb lub hoist puas puas. Nws yog nruj me ntsis txwv tsis pub nce tus naj npawb ntawm zippers kom muaj zog rub.
Kev tu
Tom qab siv, lub hoist yuav tsum tau muab ntxuav thiab coated nrog anti-xeb roj, thiab muab cia rau hauv qhov chaw qhuav kom tsis txhob muaj tes saw hoist los ntawm xeb thiab corrosion vim ya raws.
Txhawm rau kom muaj kev nyab xeeb ntawm kev siv tes saw hoist, tus neeg mob siab rau yuav tsum tau kuaj xyuas tsis tu ncua. Kev tshuaj xyuas tuaj yeem ua tiav ib xyoos ib zaug, thiab yog tias muaj cov xwm txheej tsis zoo, nws yuav siv sijhawm luv dua los kuaj xyuas. Xyuas seb cov khoom ntawm cov khoom nqa puas puas, hnav, corroded lossis muaj qee qhov kev puas tsuaj tsis zoo. Tag nrho cov cuab yeej kev nyab xeeb yuav tsum tau kuaj xyuas kom zoo thiab ua tau zoo. Cov brakes thiab cov khoom ntsuas ntsuas yuav tsum tau sim rau kev nqa. Yog tias tsim nyog, lub hoist yuav tsum tau disassembled los xyuas cov khoom hnav.

VI. Cov ntsiab lus
Cov cuab yeej tiv thaiv overload ntawm tes saw hoist tuaj yeem nres lub sijhawm thaum overloaded los tiv thaiv cov khoom hnyav los ntawm kev nqa ntxiv, yog li tiv thaiv cov khoom hnyav los ntawm kev poob thiab ua kom muaj kev nyab xeeb ntawm cov neeg ua haujlwm thiab cov khoom siv. Hauv kev siv tiag tiag, cov neeg ua haujlwm yuav tsum ua raws li kev ua haujlwm tshwj xeeb, tsis tu ncua xyuas thiab tswj lub tes saw hoist, thiab xyuas kom muaj kev ua haujlwm zoo ntawm cov khoom siv tiv thaiv overload tiv thaiv kom tsis txhob muaj xwm txheej.
