Hauv cov khoom siv tshwj xeeb, kev sib koom ua ke ntawm kev tiv thaiv hluav taws xob siab tshaj plaws rau hauv kev ua haujlwm crane tsis yog kev cai tswj hwm nkaus xwb - nws yog ib qho kev ntsuas kev nyab xeeb tseem ceeb. Phau ntawv qhia no tshawb txog qhov tseem ceeb ntawm kev tiv thaiv hluav taws xob uas tseem ceeb rau ib leeg girder cranes thiab ob chav girder cranes, qhia txog lawv lub luag haujlwm hauv kev txhawb nqa kev ua haujlwm nyab xeeb thiab kev ntseeg siab.
1. Kev tiv thaiv lub cev muaj zog: Ua kom muaj kev ua haujlwm zoo
Kev teeb tsa lub cev muaj zog nrog ntau yam kev tiv thaiv kev tiv thaiv yog qhov tseem ceeb, nrog rau kev xaiv kom haum rau lub cev muaj zog qhov tshwj xeeb tswj qhov system. Qhov sib txawv ntawm kev tiv thaiv no ua kom ntseeg tau tias, tsis hais txog kev ua haujlwm ntawm qhov xwm txheej, lub cev muaj zog tiv thaiv los ntawm kev phom sij uas tuaj yeem ua rau lawv txoj haujlwm tsis zoo lossis cuam tshuam txog kev nyab xeeb.
2. Kev tiv thaiv Circuit Court: Kev tiv thaiv hluav taws xob tsis zoo
Txhawm rau txo cov kev pheej hmoo cuam tshuam nrog luv luv Circuit Court lossis kev ua txhaum hauv av, tag nrho cov hluav taws xob hluav taws xob hauv crane systems yuav tsum muaj kev tiv thaiv overcurrent. Cov cuab yeej tiv thaiv tam sim no ua lub luag haujlwm tseem ceeb hauv kev sib txuas cov kab hluav taws xob nyob rau hauv qhov teeb meem txhaum cai, yog li tiv thaiv kev puas tsuaj lossis kev phom sij.
3. Theem Failure and Reversal Safeguards: Ua kom ruaj khov
Kev ua raws li kev tiv thaiv theem tsis ua haujlwm thiab thim rov qab yog qhov tseem ceeb, tshwj xeeb tshaj yog thaum cov hluav taws xob tsis zoo tuaj yeem ua rau muaj xwm txheej txaus ntshai. Cov kev tiv thaiv no yog tsim los nres kev ua haujlwm ntawm crane tam sim ntawd, ua kom muaj kev nyab xeeb ntawm kev ua haujlwm thaum muaj hluav taws xob tsis sib xws.
4. Zero Position Protection: Tiv thaiv kom tsis txhob ua kom tsis txhob poob siab
Crane machinery mandates suav nrog xoom txoj hauj lwm tiv thaiv rau tag nrho cov kev sib kis mechanisms. Cov yam ntxwv no ua kom cov tshuab tsis rov pib dua tom qab ua haujlwm tsis zoo lossis lub zog poob, yuav tsum tau rov pib dua phau ntawv mus rau xoom txoj haujlwm ua ntej rov pib ua haujlwm.
5. Kev tiv thaiv hluav taws xob poob: Kev ruaj ntseg cov khoom siv thaum muaj hluav taws xob cuam tshuam
Nyob rau hauv cov xwm txheej ntawm kev cuam tshuam ntawm cov khoom siv hluav taws xob, nws yog ib qho tseem ceeb uas txhua yam khoom siv hluav taws xob, tshwj xeeb tshaj yog cov uas tsis yog tsim los rau kev rov ua haujlwm tsis siv neeg, raug kaw. Qhov kev ntsuas no tiv thaiv kev ua haujlwm tsis sib xws thaum rov qab fais fab.
6. Kev tiv thaiv overspeed: Tswj ceev kom muaj kev nyab xeeb
Kev siv cov cuab yeej tiv thaiv kev kub ceev yog qhov tseem ceeb rau kev nqa cov txheej txheem uas siv thyristor -tswj stator voltage tswj, zaus hloov pauv ceev, lossis kev siv zog nres. Cov cuab yeej no yog qhov tseem ceeb hauv kev tiv thaiv kev sib tsoo vim tias muaj kev thauj khoom overspeed.
7.Interlock Protection: Txhim kho cov neeg ua haujlwm nyab xeeb
Kev tiv thaiv kev sib cuam tshuam yog qhov tseem ceeb rau kev ruaj ntseg xws li lub qhov rooj nkag mus rau choj thiab gantry cranes lossis lub qhov rooj hatch uas coj mus rau tus choj ntawm lub cab. Cov cuab yeej no ua kom muaj kev nyab xeeb ua haujlwm los ntawm kev txiav tawm lub zog rau cov txheej txheem uas tuaj yeem ua rau muaj kev pheej hmoo rau cov neeg ua haujlwm thaum lub qhov rooj qhib.
Rau kev tshawb nrhiav hauv - qhov tob ntawm peb cov cranes nruab nrog cov yam ntxwv kev nyab xeeb siab heev, peb caw koj tuaj xyuas peb nplooj ntawv khoom. Peb txoj kev mob siab rau kev nyab xeeb thiab kev ua tau zoo yog tsom rau hauv txhua yam khoom siv peb tsim, muab rau koj tsis muaj kev ntseeg siab thiab kev ua haujlwm zoo.
