Kuqhube qha crane jib RDK-250: Ukucacisa

I brand new akusoloko azalwe ukusuka ekuqaleni. Ngamanye amaxesha kubonakala ngenxa yesivumelwano phakathi kwamazwe ivelisa yaye zohlulwa. Amaxesha amaninzi, nangoku baneempawu zabazali bobabini. Umzekelo olothusayo lobuninzi sigqibo angabizwa esekelwe kwi-70 lwekhulu yokugqibela, imveliso eSoviet-German sokwakha milenge.

Ukusetyenziswa kummandla Union wakhupha uguqulelo RDK-250. iimpawu Technical, ngobuhle nangobubi, kwakunye kwimbali indalo le "silo yokwenene" phakathi oogxa bakhe, yaye siza kuqwalasela kolu phononongo.

imbali model

Ngaphambi kokuba kwimbali kwimpompo ochazwe, kubalulekile ukukhumbula ulwazi olunomdla. It wadalwa amaJamani ukuze zisetyenziswe kummandla Union. nendwe Ke kwase yemodeli German isekelwe MKG-25, sidalwe USSR. igama layo amela nje - crane kunye umthamo kweetoni 25, iingoma qha mnogokatkovyh ngayo. Okokuqala German crane qha ngaphandle kwesango Zemag Zeitz ngo-1967.

Yaba imodeli yokuqala komdyarho RDK - RDK-25. Crane ke linokuthenjwa, zifuna ulondolozo ncinane, kwaye okona kubaluleke kakhulu, unako ukusebenza phantse naluphi eqongeni. Power Machines olwenziwe mhlawumbi ngamandla yayo, okanye ukusuka yangaphandle oscillator 380 V. Ekusebenzeni, le modeli eSoviet - amaJamani awuyitshintshanga intshukumo kwenkqubo crane ngokubeka endaweni inani kweemoto, nganye elinoxanduva ngezenzo ezithile.

izigaba zophuhliso

Ngowe-1972, imodeli yokuqala Waziqhiwula imveliso. Endaweni yayo kukho oluphuculiweyo inguqulelo RDK-250. Ethwele umthamo kwendwe elitsha uhlala kwinqanaba edlulileyo, kodwa "0" kwi isihloko kufuneka ibonise ukuba olu luphuhliso ngokwesiseko esitsha.

Kubulungisa kufanele kuqatshelwe ukuba kuphela waba isityalo esitsha amandla, iibhloko aseleyo bafudukela ukuguqulwa kuqala. Crane abathengi ziye kuthathwa, ukuphawula, Noko ke, ukuba akafuni ukuya ngenxa yemigangatho zothutho kaloliwe zokuphelisa Union. Ukuze zokuhamba kuyimfuneko ukususa kuphela kwendyebo, kodwa ngaphambili, okanye ubude imithwalo engaphaya izithethe. BaseJamani siphawula lo ngobuwena isimamva "1" (eyokuqala) yaye alungiswa crane cab. Ngoko ke kukho umfuziselo RDK-250-2 - eli xesha utshintsho isebenza kuphela indawo ephezulu yokuhlala lokuqhuba.

Ukuphakamisa umthamo shazi

Kufuneka kuqatshelwe ukuba intsebenziswano kunye amaJamani baqhubeka ukuyisonga. Ngowe-1983, kwakukho milenge qha RDK-400. Nanjengoko igama layo lixela - umthamo mfuziselo neetoni ezingama-40. Le nendwe yaveliswa kwiminyaka-7, kwaye ngo-1990 phezu kwimarike kukho umatshini ukuba inani yayisele neetoni ezingama-63. yonke Umgca baseJamani ziphawulwe ngendlela efanayo: Igama lokuqala yemodeli, ngoko amanani-2 - amandla, kwaye rhoqo "0" ekupheleni - ngcono. Kulo mzekelo, njengoko kubonisiwe, hayi nje kuphela ngenxa inguqulelo Union, kodwa ngenxa amazwe CMEA. Ngaxeshanye kunye ivelufa asinde 250 RDK-280. Ukusuka isihloko kucacile ukuba belithe leza liyindoda eyahlukileyo amandla, nezinye Motors (kwimveliso eCzechoslovakia), kunye nobalo kwezinye iimeko zemozulu.

kokulungiswa

Ngokuba yiSoviet Union wavelisa-15 amawaka milenge ukuya kwiitoni-25. Ngaphandle iinguqulelo esele zikhankanywe-1 no-2, amaJamani yakhupha njengoko ezinye iinguqulelo ezimbini. Ukusebenza kwinguqulelo-yenzelwe North Far of the RDK 250-4. Sahlukile kuzo zonke iindlela zangaphambili ndlwana yothani, ekwaziyo ukusebenza kwi degrees -50, ukukhuselwa andiswe kwaye nezinye iinkcukacha.

Ukongeza kuyo, nendwe elalenziwe, ithole isalathisi "3" kwi kwisihloko. Waba ndoqhayisa iinjini diesel enamandla ngakumbi kwaye mihla, kwakunye nezinye izinto ezintsha. Omnye wabo busebenze amandla eliphezulu, apho waba kungenzeka utshintsho ngokupheleleyo ukuya komnye umthombo. Ukuba esakhiweni ngesiquphe ndiphulukene umbane - ukusebenza nendwe ukusuka diesel wenkunkuma. Last yayiquka iinxalenye ezimbini, evumela ukuba ukhubaze ngabanye, ngaphandle kokukhetha icala ukuya emsebenzini.

Iimpawu ze uphuhliso German

Mu kuya kwa nshita kwase eSoviet iitephu indibano German ayikwazanga kusetyenziselwa kuphela izakhiwo kunye nezakhiwo. Phambi kumatshini mbambe ingasetyenziswa xa kulayishwa kunye nokothula ngempumelelo. Ngenxa a kumanyano ethile, jib crane eyenziwe iJamani wakwazi ukusebenzisa uninzi nemilomo ezongezelelweyo ezisetyenziswa izithuthi eziqhelekileyo kule klasi.

zokwabelana umthwalo kwi Iimoto ezininzi ungatshintsha intshukumo kwendwe kunokwenzeka. Ukongeza imisebenzi esisiseko, uphuhliso amatsha lingasetyenziswa ukusa imithwalo enzima.

mechanism luffing

Kwanasemva kokuba uguqulelo yophuhliso RDK-250-2, xa abahamba imigama emide kunye nendwe kwafuneka ukuncothula boom. Kodwa kuyimfuneko ukuze ufumane Icala elisezantsi - ukusebenza ngqo kwi kwisiza nako ukwandisa impumelelo.

Kulo version ezingundoqo, oko linobude beemitha ezili-12. Kodwa izinto ezifakelwa ezongezelelweyo, leyo, kwakunye utolo ngokwayo, zinxibelelene amalungu umnwe, oko phantse kathathu. Ubude obukhulu kungaba 35,5 m Ukongeza, amaJamani enikiweyo ezimbini ngobuwena jib -. ubude ukugogeka nzima ka-5 m okanye ukujikajika-movably. Le yokugqibela ungandiswa.

izixhobo ozikhethela

Ithuba lolwandiso wavumela ukusetyenziswa nendwe jib hayi kuphela injongo yawo - ukuba yonyuse ukuhambisa umthwalo. Ngokutsho iinkcukacha umphuhlisi kaThixo izixhobo ezingundoqo kungaba iintlobo ezimbini - gibbet okanye neenqaba, umahluko ophambili phakathi kubo ekupheleni eliphezulu. Kodwa ke, ukongezelela kwezi ndlela zimbini, kwabakho sesithathu - mast Bawafumba ukhwele elorini njengoko nezixhobo yinqaba njengesiqhelo. Oku ngoko nangoko eyandisiweyo ukusetyenziswa kwendwe - ukusuka kwinqanaba lokuqala kugqitywa. Nesakhono ukuze uphakamise umthwalo ukuya ukuphakama kuyimitha 20 zingasetyenziswa ukwakhiwa kwezakhiwo babengabafo ngokwaneleyo.

zokuhamba crane

Abo iinkcukacha bathi RDK - mobile nendwe, Noko ke, njengoko uninzi izixhobo zokwakha, isantya ngayo intshukumo ngayo yi-1.5 km kuphela / h. Kuba off-inxuwa nga ngokuba salathisi elungileyo, ingakumbi xa ucinga ukuba akwazi ukuhamba, kunye umthwalo hook, kodwa xa ezithutha yona kwindawo entsha yomsebenzi kwafuneka ukuba usebenzise nokuba auto okanye zothutho ngololiwe.

Movement kwenziwa kwizigaba ezininzi:

• sichitha boom, iinqaba, iimasti;
• ukuhlola inkqubela yakho trawl ephantsi-bed (indlela yezothutho case);
• zokuhamba.

Kwafika ke indibano umva kwindawo entsha.

Zothutho ngololiwe oko kudla kunye uncedo lomnye nendwe, wasiwa sibekwe kwiqonga evulekileyo.

okwangoku,

AmaJamani wagqiba imveliso milenge ngo-1993. Noko ke, abaninzi zokwakha eziphakamileyo eRashiya, usenokubona ngayo. Ngenxa ukuthembeka, elula, ukukwazi ukuhamba kunye imodeli lomthwalo kwaye ngoku kwinkonzo. Kufuneka kuqatshelwe ukuba iinxalenye spare RDK-250 anokufunyanwa na mveliso omkhulu ezikhethekileyo.

Ngaba endaweni ezifakelwa zesinyithi ezisetyenziswa boom, intambo, amavili okanye ukugaqelwa ekuqokeleleni, kwezinye iinxalenye crane. Nangona ekupheleni kwemveliso, uluhlu lwezincedisi ikuvumela ukuba usebenzise olu guqulelo ixesha elide kakhulu.

singakhankanya ngokukhethekileyo ukuze ithuba ubunye, Bulelani apho nendwe angasebenzisa phantse nasiphi na isixhobo eyenzelwe ezinye imifanekiso. Kwakhona, ukusetyenziswa nezifakelo, leyo sikuphendule kube inkunzi yegusha okanye isixhobo.

iimpawu

Kweli candelo siza kuquka nabanye, wahlala phantsi kwamathunzi ngaphambili, i parameters RDK-250. Ukucacisa angamelwa ngokohlobo izintlu eziliqela. Siqala zangaphandle parameters (zonke milimitha):

• ububanzi - 3225;
• ubude - 6275;
• ukuphakama - 3350.

Yonke idatha kuphela kwendyebo kwi sikhundla zithutha.

iimpawu impahla umsebenzi esisezantsi kwendyebo kunye ifaka:

• nokuphakamisa ukuphakama (max) - 45 m;
• ubunzulu yandisa - 6 m;
• umthwalo - 25 m;
• Utyeshelo kwelona qondo - 4 no-22 m, ngokulandelelana;
• nokuphakamisa Isantya - 7.5 m / min,
• Ukwehlisa - 15.5 (kufanele kuphawulwe ukuba yandisa unako ukusebenza Motors ezimbini).
• Isantya intshukumo kunye umthwalo hook - 1 km / h, ngaphandle umthwalo - 1.5 km / h.

Oku kuquka ukuba crane yeselula yindlela olwahlula intshukumo kunye ukujikeleza, ukuze nakumphezulu elorini wakwazi ukwenza kujikelezo epheleleyo malunga axis yalo kwemizuzu emibini.

Kufuneka kuqatshelwe ukuba kulandelelwa isiseko ukuqhuba umsebenzi, nokuba kwi moya ithambekele:

• Jib ekusebenzeni - degrees-3 kwakunye nomthwalo ukuya ku-15 ngaphandle;
• kwinqaba ngobuwena - degrees 2 ubude bayo, ukuya kutsho kwiimitha-27, ngaphezulu - akukho ngaphezu kwesinye.

Ekubeni inxenye ye crane udlubu waphinda phezu iinkcukacha izithuthi uhlobo ivili olukhulu kwisisu semoto, inxenye ezantsi. Movement kwendwe yenziwa ngu pair yeemowutha kwi emigodini awo ezilungiswe amavili yokuqhuba of bogies ezinqunquthayo. Phakathi izabelo ephezulu kunye esezantsi abaqokeleli yirotary zibekiwe ukudibanisa zonke iisekethe zombane. Kuba amnike yangaphandle umthombo wamandla inesixhobo phambili cable plug kwisingxobo. Ngaphandle crane isithuba, indawo ngaphambili nga kuhlala omnye umntu. Phambi kokuba isakhelo esezantsi oyinikwa netroli uyakwazi intshukumo yokulungisa injini. Ukufikelela kwi enye motor kunye nenkqubo amandla yesondlo senziwa kumaqweqwe emazantsi.

isiphelo

Yenziwe ngenxa eSoviet-German intsebenziswano nendwe RDK-250 iye ibe lulutho ngokwenene ukwakhiwa ubunzima-1970 oluphakathi kaThixo. Ukufumaneka kunye nokukwazi ukusebenzisa izixhobo ezongezelelweyo ingaphezulu babuyekezwe iindleko kunye nobungakanani umatshini enjalo. Ngaphezu koko, lo nendwe nako ukuthenga. Ezininzi Iinkampani ezinkulu zokwakha babezimisele xa eneneni yintoni wena oko.
