Muaj nuj nqi thiab kev tu qhov tseem ceeb ntawm kev txwv kev hloov pauv hauv of elevator Safety Systems

Raws li cov cuab yeej tseem ceeb ntawm kev thauj mus los ntsug hauv cov tsev niaj hnub no, kev nyab xeeb kev ua haujlwm ntawm elevator yog ncaj qha ntsig txog kev nyab xeeb ntawm cov neeg caij tsheb. Raws li lub davhlau ya nyob twg tiv thaiv tseem ceeb hauv ntau- txheej txheej tiv thaiv kev nyab xeeb ntawm of elevator, txwv kev hloov pauv yog lub luag haujlwm rau lub luag haujlwm tseem ceeb ntawm kev tiv thaiv kev hla dhau (lossis dhau) ntawm lub tsheb hla dhau. Kev sib koom ua ke ntawm cov qauv kev nyab xeeb ntawm lub elevator thiab cov xwm txheej ua haujlwm, cov hauv paus ntsiab lus ua haujlwm, kev xav tau thiab kev saib xyuas tshwj xeeb ntawm kev txwv kev hloov pauv tau raug tshuaj xyuas.

1.Second-Line Defense hauv peb-tier system
Of elevator kev ruaj ntseg tshuab siv 'peb theem ntawm kev tiv thaiv'

• Theem 1: Thaum lub tsheb mus txog ntawm lub davhlau ya nyob twg, lub deceleration txo qis keyboards (ib qho yuam kev deceleration hloov) ua rau lub cim deceleration.
• Qib 2: Thaum lub tsheb dhau ntawm kab rov tav txoj hauj lwm theem -50mm, qhov txwv Limit keyboards (tus hloov mus rau lwm qhov) txiav tawm cov kev taw qhia circuits, yuam kom lub tsheb nres nyob rau hauv ib tug txaus ntshai kev taw qhia. Lub tsheb tseem tuaj yeem tsav mus rau qhov tsis sib xws, muab chaw rau cov neeg ua haujlwm saib xyuas ua haujlwm.
• Qib 3: txwv cov keyboards txiav tawm lub zog tseem ceeb thaum lub tsheb tseem tsav dhau los ntawm kev txwv kev txwv kev hloov pauv hloov qhov taw tes - 300mm.

Nyob rau hauv qhov kev tshwm sim ntawm ib tug deceleration hloov tsis ua hauj lwm, qhov txwv hloov cuam tshuam cov tswj Circuit Court ncaj qha los ntawm cov neeg kho tshuab kev sib cuag, xyuas kom meej tias lub tsheb nres ua ntej mus txog lub qag.

2.Technical Implementations nyob rau hauv ntau yam scenarios

• Kev Tshawb Nrhiav Txoj Haujlwm: Ua los ntawm cov phiaj xwm ntsug ntawm tus ncej kom paub meej qhov chaw nres tsheb hauv ± 50mm ntawm lub davhlau ya nyob twg.
• Kev tswj ceev: ua ke nrog tus tswj ceev - kev ruaj ntseg iav system. Yog tias lub tsheb dhau qhov ntsuas ceev, tus tswv xeev overspeed pib lub iav kev nyab xeeb ua ntej; yog tias qhov kev ruaj ntseg iav tsis ua haujlwm, qhov kev txwv txwv yuav txiav tawm lub zog.
• Kev tswj kom muaj nuj nqis: Hauv PLC raws li cov txheej txheem, txwv kev hloov pauv cov teeb liab tuaj yeem siv los ua qhov ua rau lub qhov rooj ua haujlwm thiab kev hloov pauv ceev. Piv txwv li, ib qho kev txwv tsis pub hloov pauv ua rau kev ncua sij hawm ua ntej lub tsheb mus txog lub hom phiaj hauv pem teb los ntawm ib 'meter', thiab tom qab ntawd nres kom raug los ntawm kev hloov kab rov tav.

Key Performance Parameters

• Actuation Accuracy: Hu rau actuation deviation ± 1mm, rov ua qhov tseeb tsawg dua lossis sib npaug li 0.5mm.
• Environmental Adaptability: kev khiav hauj lwm kub -10℃rau +60 degree, av noo tsawg dua los yog sib npaug rau 95%RH, tiv thaiv chav kawm ntawv IP54.
• Hluav taws xob tsis zoo: Tiv tauj qhov ntsuas AC380V / 10A, rwb thaiv tsev tiv thaiv Ntau dua lossis sib npaug ntawm 100MΩ, tiv taus hluav taws xob AC2000V / 1min.

Installation Standards

Positioning Accuracy:

• Upper / qis hloov yog mounted 50mm saum toj no / hauv qab txoj hauj lwm kab rov tav ntawm qhov chaw nres tsheb davhlau ya nyob twg.

Mechanical structure:

• Strike phaj verticality sib txawv tsawg dua los yog sib npaug li 1 hli, ntev npog tag nrho cov overtravel ntau yam.
• Hloov cov log sib tiv tauj ua los ntawm nylon thiab rotates smoothly tsis cuam tshuam.
• Cable hom txwv keyboards yuav tsum tau tensioning li tensioning yog tswj ntawm 150-200 N.

Hluav taws xob thaiv:

• Siv ob txoj hlua tiv thaiv cable Tsawg dua lossis sib npaug li 50m ntev.
• Terminal connector yog nias nrog tin -plated tooj liab lugs.
• Independent fuse ntawm kev tswj circuits (rated tam sim no 10A).

1.Txoj kev soj ntsuam cov khoom
Kev kuaj pom pom:

• Ntxuav qhov chaw ntawm qhov hloov nrog cawv ib hlis ib zaug kom tshem tawm cov plua plav; check contact yog oxidized.
• Tshawb xyuas seb cov phaj mounting bolts puas xoob thiab welds puas tawg.

Kev kuaj ua haujlwm:

• Tsav lub tsheb maj mam mus rau lub davhlau ya nyob twg thiab xyuas kom nres sai li sai tau thaum qhov kev txwv hloov ua kom qhib.
• Tig lub hloov manually thiab ntsuas kev sib cuag nrog lub multimeter.
• Tshawb xyuas qhov nro ntawm qhov kawg hloov cov hlua hlau nrog lub ntsuas qhov nro (tso cai sib txawv tsawg dua lossis sib npaug li 5%).

2.Nyob hauv-cov txheej txheem tu qhov tob
Kev tu lub hlis twg:

• Tshem tawm qhov hloov mus kuaj xyuas kev hnav khaub ncaws (hloov yog tias thickness <0.5mm).
• Lubricate mechanical kis qhov chaw nrog 5-10g calcium puag roj.
• Siv lub dial taw qhia kom ntsuas qhov kev hloov pauv hloov mus rau kev ntsuas kev sib cuag.

Kev Txhim Kho Txhua Xyoo:

• Simulate overtravel faults thiab xyuas qhov yuav tsum tau rau triple tiv thaiv linkage (Suav lo lus: "liánòng," lub ntsiab lus "chain") functionality.
• Xyuas qhov kawg hloov hlua lub log bearing thiab hloov roj (hom: 3 # lithium puag roj).
• Test hloov lub sij hawm teb (yuav tsum tau: Tsawg dua los yog sib npaug rau 0.1 vib nas this).

3.Txoj kev ua txhaum cai

Hu rau Vuam:

• Cov tsos mob: Lub tsheb txuas ntxiv mus sab nraud lub davhlau ya nyob twg.
• Ua rau: kev sib cuag tsis zoo los yog roj paug.
• Kev daws: sanding hu rau nto thiab kho kev sib cuag lub caij nplooj ntoos hlav.

False Activation:

• Cov tsos mob: txwv cov keyboards qhib ua ntej lub tsheb mus txog lub davhlau ya nyob twg.
• Yog vim li cas: Deformed ntaus phaj los yog misaligned hloov installation.
• Kev daws: Kho kom raug ntaus phaj verticality; rov pib dua hloov.

Hlau hlua tawg:

• Cov tsos mob: txwv kev hloov pauv tsis ua haujlwm.
• Yog vim li cas: hlua corrosion los yog nruj heev.

• Kev daws: Hloov cov hlua hlau (specification:Φ6mm, 6 × 19+FC); kho nro kom tau raws tus nqi.

• Nrog rau kev nce qib ntawm cov thev naus laus zis thev naus laus zis, kev txwv kev hloov pauv tau hloov los ntawm cov khoom siv ib txwm siv mus rau hluav taws xob:
• Photoelectric Limit Switches: siv cov kab hluav taws xob infrared los cuam tshuam, tshawb pom qhov tseeb 0.1mm, kev pabcuam lub neej 1 lab.
• Sib Nqus Inductive Limit Switches: Siv Hall effect sensor, hnav- ua haujlwm pub dawb, haum rau siab - of the elevator.
• Kev koom ua ke IoT: Uploads hloov cov ntaub ntawv xwm txheej mus rau huab platform rau kev saib xyuas tej thaj chaw deb thiab kev saib xyuas kev kwv yees.

Xaus:

Raws li tus neeg saib xyuas ntawm lub elevator kev ruaj ntseg system, kev ntseeg siab ntawm kev txwv kev hloov pauv ncaj qha txiav txim siab kev nyab xeeb ntawm lub elevator. Raws li cov txheej txheem kev, tsim kom muaj kev tiv thaiv kev tiv thaiv thiab siv cov cuab yeej saib xyuas kev txawj ntse tuaj yeem txo qhov kev pheej hmoo ntawm elevator overshoot / undershoot xwm txheej. Chav tsev tu yuav tsum tsim cov ntaub ntawv rau qhov kev txwv tshwj xeeb hloov, sau cov ntaub ntawv txij nkawm, muab lub hauv paus rau kev tswj hwm lub neej, thiab ua kom muaj kev nyab xeeb ntawm cov neeg caij tsheb.
