How to Choose a Four-girder Casting Loading Crane: Precise Matching for High-Temperature, Heavy-Load Scenarios

Mu bushyuhe bwo hejuru, imizigo iremereye mu nganda nk'ibyuma no kujugunya, crane yo gupakira imizigo ine, hamwe n'imiterere yayo yihariye y'imizigo ine, imiterere y'inzira enye, ubushobozi bwo gutwara imizigo ikomeye, hamwe n'imikorere ihamye, yabaye ibikoresho by'ibanze byo kuzamura no gutwara kontineri z'ibyuma byashongeshejwe nk'ibyuma by'ibyuma n'ibyuma. Guhitamo ibi bikoresho bigira ingaruka ku mutekano w'umusaruro n'umusaruro. Guhitamo nabi bishobora gutuma habaho kunanirwa kw'ibikoresho, ndetse n'impanuka z'umutekano. Therefore, enterprises must conduct a systematic evaluation from dimensions such as operational scenarios, performance parameters, and safety configurations to ensure precise matching between the equipment and operational conditions.

Kwita ku mikorere y'inzego z'ibanze, kugenzura imikoreshereze y'ubutaka

Agaciro k'ibanze ka crane yo gupakira imizigo ine iri mu bushobozi bwayo bwo guhangana n'ibihe bikomeye nka "ubushyuhe bwinshi + umutwaro uremereye + umutwaro wa eccentric." Ibikenewe mu bikorwa biratandukanye cyane mu nganda zitandukanye, bisaba igishushanyo mbonera cy'ubwubatsi.

Steel melting shop steel ladle handling: Enhanced impact resistance and thermal insulation capabilities

Amaduka yo gushonga ibyuma akunze gufata ibyuma birenze 1,600 ° C, hamwe na ladles zipima toni 300. Urujya n'uruza rw'ibyuma byashongeshejwe birashobora gutanga imitwaro ya eccentric, bisaba cyane imbaraga z'imiterere ya crane hamwe n'imikorere y'ubushyuhe:

Guhitamo imiterere y'imiterere y'ibice bine: Ibiti by'ingenzi bigomba kuba bikozwe mu cyuma cya Q355ND gifite ubushyuhe bwo hasi bwa ductile, hamwe n'uburebure bw'umuyoboro utari munsi ya milimetero 30, bwakozwe binyuze muri welding yuzuye, kugira ngo hatabaho gusenyuka kwa pulasitiki munsi y'imitwaro ya verticale n'igororotse. Igishushanyo mbonera cyinzira enye (inzira ebyiri kuri buri ruhande) gikwirakwiza imizigo ya feri, kugabanya umutwaro ku cyuma cy'uruganda, hamwe n'imizigo ya feri igenzurwa munsi ya 250 kN.

Sisitemu yo kurinda ubushyuhe: Iteraniro rya hook hamwe niteraniro rya pulley rigomba kuba rifite ibifuniko byinshi byubushyuhe (igice cyimbere cya fibre ya silicate ya aluminiyumu + igice cyo hanze cyibyuma birwanya ubushyuhe bwo hejuru) kugirango uhagarike ubushyuhe bw'imirasire kugera ku bice by'ingenzi by'ibikoresho, kugenzura ko ubushyuhe bw'ibidukikije bw'ibice by'amashanyarazi butarenga 60 ° C. Uburyo bwo kuzamura moteri n'insinga bigomba gukoresha ubwoko bwihariye burwanya ubushyuhe bwo hejuru bushobora kwihanganira 150 ° C kugirango wirinde gusaza kwa isolation.

Igishushanyo mbonera kirwanya ingaruka: Ibice bihuza hagati ya feri ya trolley n'umugozi mukuru bishyizweho nibikoresho bya buffer ukoresheje ibikoresho bya polyurethane bihanitse, bishobora gufata 80% y'imitwaro y'ingaruka z'ako kanya kugira ngo ishobore guhangana n'ingaruka zizunguruka mugihe cyo kuzamura icyuma.

Iron water ladle transportation in foundry workshops: Emphasizing precise control and stability

Ibyuma by'amazi mu bigo by'ubucuruzi bisanzwe bipima hagati ya toni 50 na 150, hamwe n'umuvuduko w'imikorere buhoro ariko ibisabwa cyane mu gutunganya neza (urugero, guhuza n'ibyambu by'umucanga). Mu guhitamo ibikoresho, hagomba kwitabwaho ibi bikurikira:

Micro-motion control performance: The hoisting mechanism is equipped with a low-speed ratio variable frequency system (1: 100), enabling stepless speed adjustment from 0.5 to 5 m / min to ensure smooth operation during pouring and prevent conften iron splashes. Uburyo bw'ibanze n'ubw'ubufasha bwa crane bukoresha uburyo bwo kugenzura umurongo ufunze, hamwe n'ikosa ryo guhagarara ≤ ± 50 mm, yujuje ibisabwa byo guhuza neza.

Dual trolley collaborative operation: Some large foundry workshops require dual trolley coordination (main trolley for lifting the iron water ladle, auxiliary trolley for cleaning). Imiterere y'ibice bine ituma imikorere yigenga ya trolleys ebyiri nta nkomyi, hamwe n'itandukaniro ryumuvuduko hagati ya trolleys zigenzurwa muri 5 m / min kugirango hirindwe amakimbirane y'imikorere.

Ivugurura ryo kurinda umukungugu: Ibigo bya Foundry bifite umukungugu mwinshi, bityo amabati yamashanyarazi agomba kuba afite sisitemu yo guhumeka umuvuduko mwiza kugirango agumane umuvuduko wimbere 50 Pa hejuru yibidukikije byo hanze, kurinda umukungugu kwinjira. Moteri na reducers zikoresha ibipimo byo kurinda IP65, kandi inzu zitwara zishyirwamo ibimenyetso bya labyrinth kugirango byongere igihe cyo kubaho kw'ibikoresho.

Kwibanda ku bintu by'ingenzi by'ingenzi byagufasha kwirinda "gukabya" cyangwa "kudahagije"

The parameter selection for four-beam casting material handling cranes must strictly match real load and operational intensity, avoid both the wasteful pursuit of excessive tonnage and the safety risks caused by insufficient parameters.

Lifting capacity: Ensure enough safety margin

The lifting capacity must cover the total of "steel ladle / iron ladle self-weight + maximum loading capacity + lifting device weight," with an additional safety margin of over 20%:

Kurugero, mugihe cyo kuzamura icyuma cya toni 100 (harimo icyuma cyashongeshejwe), hamwe nuburemere bwa toni 10, umutwaro wose ni toni 110. Crane ifite ubushobozi bwo kuzamura toni ≥132 igomba gutorwa kugira ngo ikore neza kabone n'iyo habaye umutwaro mwinshi (urugero, icyuma cyashongeshejwe cyane).

For double-girder crane models, the lifting capacity of the main and auxiliary gantries must be calculated apart. Ubushobozi bwo kuzamura gant ya gantry bubarirwa hashingiwe ku mutwaro mukuru, mugihe ubushobozi bwo kuzamura ya gantry y'ubufasha ubusanzwe ari 1/5 kugeza kuri 1/3 cy'ubushobozi bwa gantry nkuru (urugero, niba gantry nini ari toni 200, gantry y'ubufasha ni toni 50), kugirango wuzuze ibisabwa mu bikorwa by'ubufasha.

Work level: Matching operational frequency and intensity

Select the work level based on the daily operational cycle count (one cycle consists of lifting + running + lowering). Ibice bine by'imizigo yo gupakira cranes igomba kuba yujuje A7 cyangwa irenga:

Uruganda rw'ibyuma (inzibacyuho za buri munsi ≥120): Hitamo urwego rwa A8, hamwe na moteri zo kuzamura ukoresheje icyiciro cya H, hamwe nibikoresho by'inyishyuro bya feri bifasha 100.000 brake cycles nta gutsindwa, bikwiriye ibikorwa bikomeye.

Casting shop (daily cycles 50-100): Urwego rwa A7 rurahagije kugirango wuzuze ibisabwa, kugenzura igihe kirekire hamwe nibiciro byo kugura byagabanutse.

Uburebure n'uburebure bw'ibicuruzwa: Guhuza imiterere y'uruganda

Uburebure bwo kuzamura: Ugomba guhura n'intera ya verticale kuva hasi kugera ku mwanya wo hejuru w'igikoresho cyo kuzamura. Mugihe cyo kuzamura ladle yicyuma, uburebure bwo kuzamura bugomba kuba ≥ 12m (harimo uburebure bwa ladle yicyuma ya 3-5m) kugirango irebe ko ishobora kwambara ibikoresho nk'itanura ry'ibyuma n'imashini zikomeza gucana.

Span: Yemejwe hagendewe ku mwanya w'inzira mu ruganda, mubisanzwe 10-30m, Iyo uburebure burenze metero 20, igishushanyo mbonera kigomba gufata igishushanyo mbonera cyumusaraba kugirango ugabanye uburemere bwigenga 15% mugihe ugumana imbaraga, bityo bikagabanya igitutu kumurongo.

Imiterere y'umutekano wa crane y'imizigo ine igira ingaruka ku mutekano w'abakozi n'ibikoresho kandi igomba kubahiriza amabwiriza y'igihugu "Umutekano wa Cranes" n'amabwiriza yihariye y'inganda:

Multiple Braking and Limit Protection

The hoisting mechanism adopts a "dual brake + dual reducer" redundant design. Iyo feri imwe inaniwe, indi irashobora guhagarara byihutirwa mu masegonda 0.5, hamwe n'umutekano wa braking ≥1.75.

Equipped with a hoisting height limiter (to prevent the hook from hit the top), a main/auxiliary crane travel limiter (to avoid colliding with the factory building), and a boom angle limit switch (for models with boom angle adjustment function). All limit switches have a two-stage function of "alarm + shutdown."

Intelligent Monitoring and Warning System

Ibyuma by'imizigo hamwe n'abagenzuzi ba swing angle byashyizweho kugirango berekane uburemere bw'imizigo na angle ya swing mugihe nyacyo. Iyo umutwaro urenze 10% y'ubushobozi bwapimwa cyangwa angle ya swing irenze 3 °, sisitemu ihita iburira kandi ikata ingufu zo kuzamura.

Ibyuma by'ubushyuhe n'ubushyuhe bishyirwa ku bice by'ingenzi (nka feri na feri). Ukoresheje interineti y'inganda igenzurwa kure. Iyo ubushyuhe burenze 80°C cyangwa vibration idasanzwe, imiburo hakiri kare itangwa kugirango wirinde kunanirwa mu buryo butunguranye.

Emergency Backup Functionality
