2034 10t橋式起重機(jī)總體設(shè)計,10,橋式起重機(jī),總體,整體,設(shè)計 河南理工大學(xué)萬方科技學(xué)院本科畢業(yè)論文摘 要本次畢業(yè)設(shè)計是針對畢業(yè)實習(xí)中橋式起重機(jī)所做的具體到噸位級別的設(shè)計。我國現(xiàn)在應(yīng)用的各大起重機(jī)還是仿造國外落后技術(shù)制造出來的，而且已經(jīng)在工廠內(nèi)應(yīng)用了多年，有些甚至還是七八十年代的產(chǎn)品，無論在質(zhì)量上還是在功能上都滿足不了日益增長的工業(yè)需求。如何設(shè)計使其成本最低化，布置合理化，功能現(xiàn)代化是我們研究的課題。本次設(shè)計就是對小噸位的橋式起重機(jī)進(jìn)行設(shè)計，主要設(shè)計內(nèi)容是 10t 橋式起重機(jī)的結(jié)構(gòu)及運(yùn)行機(jī)構(gòu)，其中包括橋架結(jié)構(gòu)的布置計算及校核，主梁結(jié)構(gòu)的計算及校核，端梁結(jié)構(gòu)的計算及校核，主端梁連接以及大車運(yùn)行機(jī)構(gòu)零部件的選擇及校核包括: 輪壓計算及強(qiáng)度驗算, 運(yùn)行阻力計算,選擇電動機(jī),減速器的選擇驗算,運(yùn)行速度及實際功率,選擇制動器,選擇聯(lián)軸器,低速浮動軸的驗算,緩沖器的選擇等計算。還有小車的運(yùn)行和起升機(jī)構(gòu)零部件的選擇及校核包括: 運(yùn)行阻力計算，選電動機(jī)，選擇減速器驗算起動時間，按起動工況校核減速器功率，選擇制動器，選擇高速軸聯(lián)軸器及制動輪，驗算低速浮動軸強(qiáng)度，鋼絲繩的選擇，滑輪、卷筒的計算，聯(lián)軸器的選擇。關(guān)鍵詞: 起重機(jī)；大車運(yùn)行機(jī)構(gòu)；小車運(yùn)行結(jié)構(gòu)；小車起升結(jié)構(gòu)；橋架 ；主端梁 。河南理工大學(xué)萬方科技學(xué)院本科畢業(yè)論文AbstractThe graduation design is aimed at the graduation fieldwork medium-sized crane do specific to tonnage level of design. Our country is the application of the big crane or counterfeit foreign backward technology out of manufacture and has within the plant for many years, some even application or the 70s and 80s products, both in quality and in on the function can't satisfy the growing industrial demand. How to design makes it the lowest cost, decorate rationalization, functional modernization is our topic. This design is on small tonnage design of bridge crane, the main design content is 10t bridge crane structure and operation organization, including bridge structure arrangement calculation and checking the structure of the girder, the calculation and checking, calculated and checked the beam structure, the main girders connection and cart mechanism parts selection and checking including: wheel pressure calculation and intensity checking, running friction calculation, the choice of motor, gear reducer is checked, choose speed and actual power, choose brakes, choose coupling calculating speed floating axis, buffer choice calculation, etc. And car running and lifting mechanism parts selection and checking including: running friction calculation, choose motor, choose reducer, by starting checked start-up time check reducer power, choose working brakes, choose high-speed couplings and brake wheel, the checking low-speed axial intensity, the wire rope floating choice, pulley, drum calculation, coupling choice.Keywords: cranes; During operation organization; Car running structure; Car hoisting structure; Bridge; Main girders.
