Kulankhula za Crawler crane

Crane Crane
Kapangidwe kake: Crane ya crawler ili ndi mphamvu, makina ogwirira ntchito, boom, chotembenuza, ndi zida zapansi.

Crawler boom
Kuti asonkhanitse dongosolo la truss ndi zigawo zambiri, kutalika kungasinthidwe mutatha kusintha chiwerengero cha zigawo.Palinso ma jibs omwe amaikidwa pamwamba pa boom, ndipo jib ndi boom zimapanga ngodya inayake.Njira yokwezera ili ndi njira zazikulu komanso zothandizira zokwezera.Dongosolo lalikulu lokwezera limagwiritsidwa ntchito pokweza ma boom, ndipo njira yothandiziranayi imagwiritsidwa ntchito pokweza jib.

Crawler turntable
Kupyolera mu chithandizo chowombera chomwe chimayikidwa pa chassis, kulemera konse kwa turntable kumatha kusamutsidwa ku chassis, yomwe ili ndi zida zamagetsi, makina otumizira, ma hoists, makina ogwiritsira ntchito, counterweights ndi hangars.Mphamvu yamagetsi imatha kupangitsa kuti chotembenuza chizungulire 360 ​​° kudzera munjira yowotchera.Kuwombera kumapangidwa ndi ma disks apamwamba ndi otsika komanso zinthu zozungulira (mipira, zodzigudubuza) pakati, zomwe zingathe kusamutsa kulemera kwa turntable ku chassis ndikuonetsetsa kuti kuzungulira kwaulere kwa turntable.

Zigawo za Crawler undercarriage
Kuphatikizira makina oyendayenda ndi chipangizo choyendera: choyambirira chimapangitsa crane kuyenda kutsogolo ndi kumbuyo ndikutembenukira kumanzere ndi kumanja;chotsiriziracho chimapangidwa ndi chokwawa chimango, gudumu loyendetsa, gudumu lowongolera, chogudubuza, chonyamulira ndi chokwawa.Chipangizo chamagetsi chimazungulira gudumu loyendetsa pamtunda wowongoka, shaft yopingasa ndi kufalikira kwa unyolo, potero kuyendetsa gudumu lowongolera ndi gudumu lothandizira, kuti makina onse agubuduze panjira ndikuyenda.

Crawler magawo
Pali kukweza kulemera kapena mphindi yokweza.Kusankhidwa makamaka kumadalira kulemera kokweza, utali wogwirira ntchito ndi msinkhu wokweza, womwe nthawi zambiri umatchedwa "kukweza zinthu zitatu", ndipo pali mgwirizano woletsana pakati pa zinthu zitatu zonyamulira.Mawonekedwe aukadaulo wake nthawi zambiri amatengera graph yokweza curve kapena tebulo lofananira la digito la magwiridwe antchito.

Crane ya crawler imadziwika ndi ntchito yosinthika, imatha kuzungulira madigiri a 360, ndipo imatha kuyenda ndi katundu pamalo athyathyathya komanso olimba.Chifukwa cha ntchito ya chokwawa, imatha kugwira ntchito pamtunda wofewa komanso wamatope, ndipo imatha kuyendetsa pamtunda wovuta.Pomanga nyumba zomangidwa kale, makamaka pakuyika nyumba zanyumba zanyumba imodzi, ma crawler craw amagwiritsidwa ntchito kwambiri.Choyipa cha crawler cranes ndikuti kukhazikika kwake ndi koyipa, sikuyenera kuchulukitsidwa, liwilo loyenda limachedwa, ndipo chokwawa ndichosavuta kuwononga msewu.

Ma crawler craw omwe amagwiritsidwa ntchito popanga ma projekiti amaphatikiza mitundu iyi: W1-50, W1-100, W2-100, Northwest 78D, ndi zina zambiri. Kuphatikiza apo, pali mitundu ina yochokera kunja.

Chingwe chokwawa chopinda W1-50
Mphamvu yokweza kwambiri ndi 100KN (10t), chowongolera cha hydraulic chimaphatikizidwa kuti chigwire ntchito, ndipo boom imatha kukulitsidwa mpaka 18m.Crane yamtunduwu ili ndi thupi laling'ono.Zitha kuwoneka kuchokera patebulo la 6-1 kuti m'lifupi mwa chokwawa chimango ndi M = 2.85m, ndipo mtunda kuchokera kumchira mpaka pakati pa kuzungulira A = 2.9m, kulemera kwake, kuthamanga kwachangu, kumatha kugwira ntchito mopapatiza. malo, oyenera ma workshop ang'onoang'ono okhala ndi kutalika kochepera 18m ndi kutalika kwa unsembe pafupifupi 10m, ndikuchita ntchito zina zothandizira, monga kutsitsa ndi kutsitsa zigawo, ndi zina.

Chopinda chokwawa cha W1-100
Mphamvu yokweza kwambiri ndi 150KN (15t), ndipo imayendetsedwa ndi hydraulically.Poyerekeza ndi mtundu wa W1-50, crane iyi ili ndi thupi lalikulu.Zitha kuwoneka kuchokera ku Table 6-1 kuti m'lifupi mwake chimango chokwawa ndi M = 3.2m, ndipo mtunda kuchokera kumchira kupita pakati pa kasinthasintha ndi A = 3.3m, liwiro likuchedwa, koma chifukwa cha kukweza kwakukulu. mphamvu ndi kukula kwanthawi yayitali, ndikoyenera pa msonkhano wokhala ndi kutalika kwa 18m ~ 24m.

Chingwe chokwawa chokhazikika W1-200
Mphamvu yokweza kwambiri ndi 500KN (50t), makina akuluakulu amawongoleredwa ndi kuthamanga kwa hydraulic, makina othandizira amawongoleredwa ndi lever ndi magetsi, ndipo boom imatha kupitilira mpaka 40m.4.05m, mtunda kuchokera kumchira mpaka pakati pa kasinthasintha ndi A = 4.5m, yomwe ili yoyenera kuyika m'mafakitale akuluakulu.
