Gwadon Tattaunawa na Disconectors na Kwasuwa a Makwabtunai

A cibiyar kogin gina, masu taka makamanin da aka sauya akan zoncin da suka faru da matsaloli kamar tafiya, kuskuren zurfaffa, sayan yawa da kuma rashin mahimmancin dambe na tsari mai wuyar wani abu, wanda ya bada muryuka sosai ga alaka mai sauƙi. Yanzu ana buƙatar ayyukan gyara teknikun waɗannan cibiyoyin da suka dauki shekaru manyi. Lokacin waɗannan gyaran, don karɓar sauyin kasuwancin mutane, irin aiki ne a halin yanzu ce taɓatawa shafin da ke gyara sai dai kuma wasu shafuka suna da elekata. Amma wannan hali na aiki ke kawo zuwa rashin furo daidaita tsakanin abubuwan da ke gyara da wasu abubuwan da suka da elekata, kuma bai yi haɗin dakin nisar taimako na ayyukan kama ba—wanda ya kawo matsalar girman ayyukan gyara. Sai dai yayin da wasu shafuka baya iko samun elekata, masu kama maras gargadi ba za su iya aiki don dalilin masifa.

Don iko kama da gyara cibiyoyin a cikin waɗannan juyawan da suke da matsaloli, muna koya matsalolin da aka gamu kuma muna kira kan farko da kuma farko na abokin kama mai amfani da cibiyoyin cikin jerin da suke da masifa, don haka muna bada kwabo mai tsada don gyara abubuwan kogin gina.

Bayan koyon buƙatar farko da kuma dubawa kan jerin crane mai yawa, kuma rubuta ban tsarin cibiyar high-voltage 110 kV, mun samo cewa ane rage mesin kama bisa kan tsakon cibiyar cibiyar yadda ya kamata, wanda ya bada tsayin, kare dalilin wurin, kama da kyau da yawa cikin juyawa, kuma iko kawo mutane uku su rarraba da kuma sanya abubuwan kama (kamar yadda ya nuna nan baya).

I. Tsarin Masu Kama

Bisa kafa kowane aiki, masu kama ana kirkiransu zuwa hudu kama garuruwa: hoisting, traveling, slewing, da luffing mechanisms.

(1) Hoisting Mechanism
Hoisting mechanism ya ƙunshi abubuwan mai amfani, abubuwan mai sauya, tsarin wire rope, da abubuwan mai sauri/kari. Matakan kuɗi sun hada da motar elektiriku ko internal combustion engines. Tsarin wire rope ya ƙunshi kwallo, drum assemblies, da jerin pulley mai canzawa da mai tsayawa. Abubuwan mai sauya suna da nau'ikan biyu—kamar lifting eyes, spreader beams, hooks, electromagnetic lifters, da grabs. Bayan rubuta buƙatar farko da kuma cibiyar cibiyar cibiyar, da kuma koyon crane mai yawa, mun zaɓi winch mai tsauri ko compact winch kamar abubuwan mai amfani da hook kamar abubuwan mai sauya.

(2) Traveling Mechanism
Traveling mechanism yana canza wuri crane a kewaye don iko kama da wuri mai aiki. Yana ƙunshi sistema mai tsayawa da sistema mai amfani. A farkonmu, muna amfani da sistema mai tsayawa mai alama, inda kwallo mai nasara suna tafiya kan steel channel na tsakon cibiyar cibiyar. Wannan hali yana da rashin resistance, mahimmancin tsayawa, kyau mai zurfi, da saukin kirkirar da kuma gyara. Don dalilin yawan wuri mai kewaye, sistema mai amfani yana amfani da mutum don saukin.

(3) Slewing Mechanism
Slewing mechanism ya ƙunshi slewing bearing assembly da slewing drive unit. Slewing bearing yana tsayawa mai canzawa kan column mai tsayawa, yana kiyaye canje-canje mai tsayi da kare mutuwar ko kututtuwa. Slewing drive yana bada torque don canje-canje da kuma kare matakan canje-canje.

(4) Luffing Mechanism
A cibiyar jib-type cranes, wuri tsakanin slewing centerline da load handling device centerline an kiran "radius". Luffing mechanism yana canja wannan radius. Bisa kafa karakterin aiki, luffing mechanisms ana kirkiransu zuwa operational ko non-operational.

Operational luffing ya faru bayan zaɓi, kuma an amfani da shi don canja radius bayan kama—to mimic collision bayan kama ko don align precisely with workstations—yana buƙatar iyaka mai yawa don iko kama da efficiency.

Non-operational luffing ya faru baya zaɓi, kamar wuri ne don sauya hook bayan kama ko don fold boom don transport. Waɗannan ayyukan baya su faru sosai kuma su amfani da iyaka mai qaranci.

II. Weighing Abubuwan Masu Kama
Don dalilin wannan abokin kama shine modular, portable small crane, weigh abubuwan yana muhimci. Weigh mai yawa zai kasa iko kama da mutane 2–3, kuma zai iya kasa iko kama. Don haka, abubuwan mai muhimmanci suna da titanium alloy, inda abubuwan mai yawa suna da 46 kg kawai—don iko kama da mutane uku su rarrabe da sanya.

III. Procedure na Kama
Tsarin kama na high-voltage disconnector ta hanyar wannan aboki shine haka:
Kama, masu aiki su sanya insulated ladder bisa kan steel channel na tsakon cibiyar cibiyar. Daga ladder, su rage base plate na crane bisa kan steel channel ta hanyar guide-wheel clamping assemblies, tare da guide wheels sun fito cikin channel don kare mutuwar ko kututtuwa.

Bayan installation base, masu aiki biyu su sanya boom support na crane bisa kan SE7 slewing bearing, sannan su rage compact winch sama shi. Sannan su sanya main boom, auxiliary boom, da hydraulic cylinder. Hydraulic pump da control buttons suna cikin wurin. Bayan an kunna, masu aiki za su iya aiki dukkanin dari.

Kuma, crane ya ƙunshi uku kwabo mai kwabo:

• High-voltage proximity warning: Sensor na electric field a hoton boom ya kirkiri voice alarm da automatic braking lokacin da safe distance tsakanin abubuwan da suka da elekata ya barce.

• Overload protection: Strain sensor a hoton wire rope connection yana magana load weight da lifting angle; violation yana kirkiri alarm da automatic braking.

• Power-loss protection: Lokacin da an ci electricity bayan kama, system yana auto-lock don kare load drop.

IV. Mafiyan da Turancin Zabu a Kunnin

• Yana aiki da sannan mai sarrafa kashi da na tsauci don bayar waraɗi a tunani game da abu a kan gaba da zama a cikin kashi da yawa, tare da magana a tunani da yanke da yaɗa.

• Tana da babban mai dace mai girma da ke kula a kan kungiyar zabu, wanda yake taimaka waɗanda suka fito da zama a cikin kashi da yawa.

• Abubuwa masu muhimmanci (kashi, tsakiyar zabu, takarda) suna amfani da alwadannin titani—wanda yake taimaka waɗanda suka fito da zama da kuma sa shirya.

• Kunna aiki na tsohon aiki yana taimakawa waɗanda suka fito da zama a cikin duk fata, tare da taimaka waɗanda suka fito da zama a cikin rike da aiki da kullum.

A hagu, wannan zabu na amfani da alwadannin titani don abubuwan da ke muhimmanci don kawo shirya, tare da kunna aiki na tsohon aiki don koyar da karkashin aiki da karamin aiki, tare da buƙatun mutane uku don aiki. Yana taimaka waɗanda suka fito da zama a cikin karfin aiki a cikin wurin da ke da damuwa da kuma wurin da ke da ƙarin abu, a matsayin halin aiki na mafi yawan abin da za su iya amfani da shi.
