Imigangatho yovavanyo ye-lever hoists

Izinto eziqhelekileyo zovavanyo lwe i-lever hoists

(1) Uvavanyo olungekho umthwalo: Tsala i-lever yangaphambili kunye ne-reverse lever ngasemva nangaphambili kathathu xa kungekho mthwalo, kwaye uqaphele imeko yokusebenza kwendlela. Kufuneka kungabikho jamming.

(2) Uvavanyo lomthwalo olulinganisiweyo: Uvavanyo kwibhentshi yovavanyo olukhethekileyo, amandla okutsalwa kwesandla kunye nentambo yocingo ebuyelayo yokubetha umqheba kufuneka ihlangabezane neemfuno eziqhelekileyo.

(3) Uvavanyo lomthwalo oguquguqukayo: Uvavanyo kwibhentshi yovavanyo olukhethekileyo, layisha ngokuphindwe kayi-1.1 umthwalo olinganisiweyo, ukunyuka nokuwa kanye, kwaye umgama wokuhamba ngentambo yentambo akufanele ube ngaphantsi kwe-200mm ngexesha ngalinye. Umatshini wonke kufuneka usebenze kakuhle kwaye uthembekile.

(4) Uvavanyo lomthwalo we-static: Kwibhentshi yovavanyo olukhethekileyo, ngokuthe ngcembe ulayishe kumaxesha e-1.5 kumthwalo olinganisiweyo kwaye uhlale imizuzu eyi-10. I-clamps kunye ne-clamping plates ayiyi kubangela i-deformation esisigxina echaphazela ukusebenza.

(5)Uvavanyo lwehuka:

① Kumatshini wokuvavanya imathiriyeli, ngokuthe ngcembe layisha ukuya kuthi ga kwi-2 yomthwalo olinganiselweyo kumbindi we-hook cavity, emva koko uwususe umthwalo emva kokuhlala umzuzu omnye. Khangela ukuguqulwa komlomo we-hook, ongayi kudlula i-0.25%;

② Kumatshini wokuvavanya izinto eziphathekayo, ngokuthe ngcembe ulayishe ukuya kumaxesha angama-4 umthwalo olinganisiweyo phakathi kwe-hook cavity, kwaye ikhonkco kufuneka ikwazi ukuxhasa ngokuthembekileyo ngomzuzu we-1.

(6) Uvavanyo lokuthembeka: Ngaphantsi komthwalo olinganisiweyo, ngokuqhubekayo utsale i-lever yangaphambili kunye ne-lever umva ngasemva naphambili ukuze i-cumulative back-and-out stroke yentambo yocingo ingabi ngaphantsi kwe-120m (ingenziwa kumaxesha amane, kodwa ixesha ngalinye, kodwa ukubetha okuqokelelweyo kwentambo yocingo ngexesha ngalinye kwi-30m, kwaye ikhefu phakathi kwe-1 yeyure ayivumelekanga ukuba idlulise indawo ye-1 yeyure. uvavanyo). Kufuneka kungabikho nto ingaqhelekanga kuyo nayiphi na indawo ye-lever hoist.

(7) Ukuhlolwa komgangatho wenkangeleko: Umphezulu wehuku kufuneka ugudiswe kwaye ucoceke, kwaye kungabikho ziqhuma, iintanda, ukugotywa, okanye iziphene zasekuhlaleni ezinciphisa amandla; akukho welding yokulungisa ivunyelwe kwi-hook. Umphezulu we-clamping plate kufuneka uqonde kwaye ungabi nama-burrs. Iziphelo zentambo yocingo kufuneka zijikelezwe kwaye zingakhululeki. Akukho maqhina, amaqhuma okanye i-twist avunyelwe kuyo yonke intambo. Ukukrazuka kwamalungu kufuneka kuqine, kwaye iintloko ezikrazukileyo azifanele zibe neziphene ezinjengokukhanya, iintanda, okanye imikrwelo. Indawo epeyintiweyo kufuneka ilingane kwaye igqame ngombala. Kufuneka kungabikho amabala, amaqamza, imibimbi, ukuxobuka kunye noburhabaxa.
