Eyayimfuqa abakhasi crane jib RDK-250: Imininingwane

Sha omusha hhayi njalo ozalwa kusuka ekuqaleni. Ngezinye izikhathi kubonakala ngenxa yesivumelwano phakathi kwamazwe esikhiqiza bese ahlukaniswe. Isikhathi esining impela, namanje nokuthi unezici ezithile zabo bobabili abazali. Isibonelo esimangalisayo leso sinqumo kusengathiwa ezinze e-70 leminyaka eledlule, ukukhiqizwa Soviet-German yokwakhiwa Cranes.

Ukuze ukusetshenziswa ensimini ka-Union ekhishwe okufushane RDK-250. izici Technical, ngobuhle nangobubi bawo kanye umlando yokudalwa kwendawo "silo real" phakathi ozakwabo, futhi sizoxoxa ngale isibuyekezo.

umlando imodeli

Ngaphambi kokuvala ukuze umlando empompini kuchaziwe, kuyafaneleka iqiniso ezithakazelisayo. It yadalwa amaJalimane ukusetshenziswa endaweni Union. crane Kodwa-prototype imodeli German kusekelwe MKG-25, wadala e-USSR. Igama layo zazimeleleni nje - crane ephethe namandla amathani 25, mnogokatkovyh abakhasi amathrekhi. Okokuqala crane abakhasi German ngesango Zemag Zeitz ngo-1967.

Kwakuwusuku imodeli lokuqala RDK uchungechunge - RDK-25. Crane kwaba okuthembekile, zidinga yesondlo incane khona, futhi okubaluleke kakhulu, ungasebenza sanoma yisiphi yesikhulumi. Amandla Machines kwenziwe noma ngamandla ayo, noma kuqhamuka zangaphandle oscillator 380 V In practice, lokhu kwaba imodeli KwabaseSoviet Kwakugxile Khona - amaJalimane zishintshile ukuhamba uhlelo crane ngokumisa eziningi motor, ngamunye okuyinto ngezenzo ezithile.

izigaba yentuthuko

Ngo-1972, imodeli kuqala likhishwa ukukhiqizwa. Esikhundleni salo kukhona inguqulo ethuthukisiwe ye RDK-250. Ukuthwala umthamo we crane entsha uhlala ezingeni odlule, kodwa "0" esihlokweni kufanele bakhombise ukuthi lena ukuthuthukiswa ngokuyinhloko entsha.

Uzokwenza kufanele kuphawulwe ukuthi kuphela waba yinkosi entsha amandla plant, amabhlogo osele sishukumiseleka ukuba ukuguqulwa kuqala. Nokho baye amakhasimende Crane athathwe, nekucaphela, ukuthi ingahambi izindinganiso izitimela yokutholwa Union. Ukuze zokuhamba kuyadingeka ukuze asuse hhayi kuphela boom, kodwa ngaphambili, noma ukuphakama wezimpahla kungaphezu kwezinkambiso. AmaJalimane ukumaka le samuntu the isijobelelo "1" (kuqala) kanye kusetshenzwe crane cab. Ngakho kukhona model RDK-250-2 - kulokhu izinguquko zisebenza kuphela ukuphakama cab somshayeli.

Ukuphakamisa umthamo shazi

Kufanele kuqashelwe ukuthi ngokubambisana neNhlangano amaJalimane aqhubeka ugoqe. Ngo-1983, kwakunabamemezeli abangu-abakhasi Cranes RDK-400. Njengoba leli gama lisikisela - namandla imodeli kwaba amathani 40. Lokhu crane yadalwa iminyaka 7, futhi ngo-1990 emakethe kukhona umshini ukuthi babengamaphesenti kakade amathani 63. Yonke umugqa lamaJalimane ibhalwe ngendlela efanayo: igama lokuqala imodeli ke 2 amadijithi - umthamo, futhi njalo "0" ekupheleni - ngcono. Kulokhu, njengoba kuphawuliwe, hhayi nje ngobe kutawutfutfukisa nguqulo Union, kodwa nezalo amazwe CMEA. In parallel valve wangenela 250 RDK-280. Kusukela isihloko kuyacaca ukuthi wayenobuhlobo umthamo ezahlukene, nezinye izinjini (eCzechoslovakia ukukhiqizwa), kanye ekubalweni lezinye izimo zomkhathi.

ukulungiswa

Ukuze eSoviet Union ekhiqizwa Cranes angaba yizinkulungwane 15 kuya amathani 25. Ngaphandle izinguqulo sekushiwo 1 no-2, amaJalimane olukhishwe njengohlelo ukulungiswa ezimbili phambili. Ukusebenza version Far North-eklanyelwe we RDK 250-4. Sasihlukile kuzo zonke onobuhle yangaphambili gumbi sekuqala ukufudumala, uyakwazi ukusebenza -50 degrees, Ukuvikelwa ethuthukisiwe kanye neminye imininingwane.

Ngaphezu ke, kwenda wawenziwe, uthole i-index ezengeziwe "3" esihlokweni. Wayengase ukuziqhayisa ezinamandla kakhudlwana futhi yesimanje diesel, kanye ezinye ezintsha. Omunye wabo kwakungu-eziphambili amandla busebenze owawunesihloko kungenzeka inkinobho ephelele komunye umthombo. Uma esakhiweni ngokungazelelwe silahlekelwa ugesi - operation crane kusuka generator diesel. Kugcine laliyizingxenye ezimbili, ezikuvumela ukukhubaza ngazinye, ngaphandle kokubukela phansi umsebenzi.

Izici ukuthuthukiswa German

Ngokungafani prototype Soviet ompompi inhlangano German ayengenakusetshenziswa kuphela ekwakhiweni kwezakhiwo kanye nezakhiwo. Ephambi kwezinduna umshini sokudonsa kungenziwa ngokuphumelelayo esetshenziselwa yokulayisha athula. Ngenxa a ubunye ezithile, jib crane eyenziwe eJalimane owakwazi ukusebenzisa iningi Imibhobho esemzimbeni ezengeziwe esetshenziselwa izimoto ezivamile kuleli kilasi.

umthwalo ukwabelana izinjini eziningi angashintsha ukunyakaza kunokwenzeka le-crane. Ngaphezu imisebenzi eyisisekelo, ezintsha kungasetshenziselwa ukuhambisa imithwalo esindayo.

luffing indlela

Ngisho nangemva kokuba inguqulo yokuthuthukisa RDK-250-2, uma uvakasha olude nge crane kwadingeka ukuba ahlukanisa boom. Kodwa kubalulekile ukuthola sinazo - ukusebenza ngqo kusayithi onganikeza boom.

In the version eyisisekelo, it has a ubude 12 metres. Kodwa nge ifaka ezengeziwe, okuyinto, kanye umcibisholo ngokwayo, banamathela emalungeni umunwe, kungashiwo cishe kathathu. Ubude obukhulu kungaba 35,5 m kwalokho, amaJalimane enikeziwe jib samuntu ezimbili -. immobile obuphelele kanzima 5 m noma swivel-movably. Lesi sakamuva angase enwetshiwe.

imishini ozikhethela

Kungenzeka isandiso avunyelwe ukusetshenziswa crane jib hhayi kuphela inhloso yazo - ukuthi siphakamise bese ukuhambisa umthwalo. Ngokusho Ukucaciswa lonjiniyela imishini eziyisisekelo kungaba ezimbili zama - gibbet nofana imibhotjhongo, umehluko oyinhloko phakathi kwabo kwakukhona ekupheleni engenhla. Kodwa-ke, ngaphezu ezimbili lezi ongakhetha, kwakukhona yesithathu - insika enqwabelanisa ogibele cab njengenjwayelo imishini umbhoshongo. Lokhu ngokushesha enwetshiwe ukusetshenziswa crane - kusukela izigaba sokuqala kuze kube sekupheleni. Futhi ikhono siphakamise load ukuphakama kwamamitha 20 ingasetshenziswa ukuze kwakhiwe izakhiwo yokuphakama okwanele.

zokuthutha crane

Labo Ukucaciswa zithi RDK - mobile crane, Nokho, njengoba iningi imishini yokwakha, isivinini siqu ukunyakaza kuyinto nje 1.5 km / h. Ukuze kokufunda ke kungenziwa ngokuthi inkomba, ikakhulukazi uma ucabangela ukuthi yayikwazi ukuhamba, nge umthwalo hook, kodwa nalapho bethutha kuso endaweni entsha emsebenzini kwadingeka ziyalisebenzisa auto noma izitimela.

Movement senziwe izigaba eziningana:

• ukuqaqa lesi boom, imibhoshongo, insika;
• hlola intuthuko yakho kwi yokudoba okulala ongaphakeme (umgwaqo zokuthutha icala);
• zokuthutha.

Kwabe sekufika inhlangano reverse endaweni entsha.

Ukuze ezokuthutha ngesitimela ngokuvamile ngosizo omunye crane, idluliselwe futhi zabekwa isiteji evulekile.

okwamanje,

AmaJalimane Uqede ukukhiqizwa Cranes ngo-1993. Noma kunjalo, abaningi ukwakhiwa ephezulu liphumele eRussia, usengayibona ke. Siyabonga ukuba nokwethenjelwa, ubulula ikghono nge imodeli umthwalo futhi manje enkonzweni. Kufanele kuqashelwe ukuthi le RDK-250 izingxenye ezisele zingatholakala kunoma iyiphi workshop esikhulu ezikhethekile.

Ungashintshanisa ifaka metal ngenxa boom, intambo, amasondo noma crawlers e ukuhlangana, kwezinye izingxenye crane. Naphezu ekupheleni ukukhiqizwa, kwezesekeli ikuvumela ukuba usebenzise le nguqulo isikhathi eside kakhulu.

isizathu esikhethekile sokuba kukhulunywe kungenzeka kungenzeka wokwakha ubunye, sibonga ngalo crane angasebenzisa cishe kunoma iyiphi idivayisi yakhelwe kweminye imihlobo. Futhi, ukusetshenziswa nezinamathiselo, okuyinto sikuphendule kube inqama noma Rig.

izici

Kule ngxenye sizothola nifake nabanye, wahlala izithunzi ngaphambi, nemingcele RDK-250. Imininingwane kungenziwa amelwe ngesimo uhlu eziningana. Thina siqale nemingcele yangaphandle (zonke ngamamilimitha):

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

Yonke idatha okukhethekile boom kule sikhundla zithutha.

Cargo izici for umsebenzi okujwayelekile boom nge ifaka:

• ephakamisa ukuphakama (ubuningi) - 45 m;
• ukwehlisa ukujula - 6 m;
• umthwalo - 25 m;
• Ukusuka esiphezulu futhi ubuncane - 4 no-22 m, ngokulandelana;
• isivinini ephakamisa - 7.5 m / imiz,
• Ukwehlisa - 15.5 (kufanele kuphawulwe ukuthi wehlise ongasebenza izinjini ezimbili).
• ijubane lokuya nge umthwalo hook - 1 km / h, ngaphandle umthwalo - 1.5 km / h.

Lihlanganisa ukuthi crane mobile has a indlela ekwehlukaniseni tenhlangano ukujikisa, ukuze engxenyeni engenhla cab ngakwazi ukwenza umjikelezo ogcwele emhlabeni axis awo ngemizuzu emibili.

Kufanele kuphawulwe ukuthi zilandelwa ngesisekelo zokuqhuba umsebenzi, ngisho kundiza enalokho kuthambekela:

• Jib ekusebenzeni - 3 degrees futhi ngezinye nomthwalo kufika ku-15 ngaphandle;
• e samuntu umbhoshongo - 2 degrees at ubude balo, kuze 27 metres, ngenhla - akukho engaphezu kweyodwa.

Kusukela engxenyeni ujikelezisa kukaNohemu cishe iphindwa ku umniningwane isondo uhlobo izimoto mkhulu phezu chassis, isabelo ongezansi. Movement of the crane yenziwa ngu pair izinjini ku imiphini zazo wahlela amasondo ukushayela zamacimbi bogies. Phakathi izingxenye engenhla nengezansi abathelisi rotary kuthiwa ngisho nokubekwa yokuxhuma zonke izifunda kagesi. Ukuze powering kumthombo wamandla ongaphandle inikezwa lead ikhebula ipulaki emkhonweni. Ngaphandle isikhala crane, ngaphambili bangahlala omunye umuntu. Eme phambi kwaleso Uhlaka engezansi okuvalelwe inqola i-injini ukulungisa ukunyakaza indlela. Ukufinyelela nezinye motor namandla uhlelo yesondlo yenziwa ngokusebenzisa nesembozo phansi.

isiphetho

Wadala ngenxa eSoviet-German nokubambisana crane RDK-250 isibe iyisibusiso real ukwakhiwa isisindo ekuseni futhi maphakathi nawo-1970. Ukutholakala kanye ikhono lokusebenzisa impahla eyengeziwe ingaphezu ihlawulelwa izindleko kanye nosayizi umshini ezinjalo. Ngaphezu kwalokho, i-crane akakwazanga ukuthenga. Izinkampani eziningi ezinkulu zokwakha babezimisele lapho empeleni yini ukunikeza it out.
