Yakajairika nzira dzekuongorora dzema lever hoists

Pane nzira nhatu dzinowanzo shandiswa dzekuongorora dzelever hoist: kuongorora kwekuona, kuongororwa kwebvunzo, uye kuongorora kwekuita mabhureki.Pazasi isu tichatsanangura idzi nzira dzekuongorora zvakadzama imwe neimwe:

1. Kuongorora kwemaziso

1. Zvikamu zvese zveratchet lever hoistinofanira kugadzirwa zvakanaka, uye hapafaniri kuva nekuremara kwakadai semavanga uye burrs anokanganisa kuonekwa kweZhilian.

2. Mamiriro echeni yekusimudza anofanira kuraswa pasi pemamiriro anotevera:

A. Corrosion: Kumusoro kwecheni kwakasvibiswa mugomba kana kuti chip inofukunurwa.

B. Kunyanya kupfeka kwecheni kunodarika 10% yedhayamita yezita.

C. Deformation, kuputika uye kukuvara kwekunze;.

D. Chimiro chinova chinodarika 3%.

3. Mamiriro ehuku, zvinotevera zvinofanirwa kuraswa:

A. Pini yekuchengetedza yechirauro yakakanganiswa kana kurasika.

B. Kutenderera kwechirauro kune ngura uye haigone kutenderera zvakasununguka (360° kutenderera)

C. Hoko yakasakara zvakanyanya (kupfuura 10%) uye chirauro chakaremara (chinopfuura 15% muhukuru), torsion (kupfuura 10 °), kuputika, acute angles, corrosion, uye warpage.

D. Themanual lever hoistinofanirwa kuve yakashongedzerwa neyakakodzera cheni inovharira mudziyo wekubatsira mukuita kwakaringana kwecheni uye sprocket, uye kana iyo lever hoist yaiswa uye inozununguka pakuda, ita shuwa kuti cheni haigone kudonha kubva kune sprocket ring groove.

2. Nzira yekuedza

1. Hapana-mutoro chiito bvunzo: Mune hapana-mutoro mamiriro einotakurika lever hoist, dhonza mubato uye chinjairira chirauro kuti chiredzo chisimuke nekudonha kamwe chete.Imwe neimwe meshini inofanirwa kushanda ichichinjika, uye hapafanirwe kunge paine jamming kana tightness.Bvisa iyo clutch mudziyo uye dhonza ketani neruoko, iyo inofanirwa kuve yakareruka uye inoshanduka.

2. Dynamic load test: Zvinoenderana nemuyedzo we1.25 nguva, uye zvinoenderana neyakatsanangurwa bvunzo yekusimudza urefu, inosimudzwa nekudzikiswa kamwe chete.Panguva imwecheteyo, zvinotevera zvinodiwa zvinofanira kuzadzikiswa.To

A. Cheni yekusimudza uye sprocket yekusimudza, cruise ship, hand zipi uye ruoko sprocket mesh zvakanaka;

B. Kufambisa kwegiya kunofanira kunge kwakadzikama uye kusina zviitiko zvisina kujairika.

C. Kushungurudzwa kweketani yekusimudza panguva yekusimudza nekudzikisa;

D. Mubato unofamba zvakanaka, uye simba rerevheti harina shanduko huru;

E. The bhureki chiito chakavimbika.

3. Braking performance test

Takura mutoro unoenderana neyakatemerwa bvunzo, uye uedze iyo munhevedzano katatu.Yekutanga bvunzo mutoro 0.25 nguva, kechipiri nguva 1, uye kechitatu nguva 1.25.Munguva yekuedzwa, mutoro unofanirwa kuwedzerwa ne 300mm, uye ipapo mutoro unofanirwa kuderedzwa nemaitiro ekunyora kusvika pakukwirira kwekusimudza sprocket, uye ipapo kumira 1h, zvinhu zvinorema hazvifaniri kuwira zvakasikwa.
