2011 屆畢業(yè)設(shè)計(jì)(論文) 建筑卷揚(yáng)機(jī)及其排繩機(jī)構(gòu)的設(shè)計(jì) 系 、 部: 機(jī)械工程系 學(xué)生姓名: 魏熙陽 指導(dǎo)教師: 羅建華 職稱 教授 專 業(yè): 機(jī)械設(shè)計(jì)制造及其自動(dòng)化 班 級(jí): 機(jī)本 0704 學(xué) 號(hào): 214070424 完成時(shí)間: 2011 年 6 月 摘 要 建筑卷揚(yáng)機(jī)是一種起重設(shè)備,由于其結(jié)構(gòu)簡單、制造成本低、操作方便、 對(duì)作業(yè)環(huán)境適應(yīng)性強(qiáng),因此在建筑、工業(yè)、農(nóng)業(yè)、海運(yùn)、交通、化工、冶金 和油田等部門中用于起重、拖重物等工作,也是每個(gè)建筑工地、每個(gè)工程隊(duì) 必不可少的設(shè)備。在施工工地上,卷揚(yáng)機(jī)鋼絲繩在繩筒上繞制常常發(fā)生錯(cuò)亂, 這樣,鋼絲繩相互擠壓,磨損嚴(yán)重,縮短了鋼絲繩的使用壽命;同時(shí),與卷 揚(yáng)機(jī)配用的限位裝置普遍為重錘式或螺桿式。重錘式安裝維修不便,螺桿式 由于鋼絲繩排繞錯(cuò)亂而導(dǎo)致限位失靈。為了克服以上缺點(diǎn),在卷揚(yáng)機(jī)上附加 了一種排繩機(jī)構(gòu)。排繩機(jī)構(gòu)的設(shè)計(jì),以減速箱齒輪提供的轉(zhuǎn)動(dòng),驅(qū)動(dòng)使排繩 機(jī)構(gòu)往復(fù)直線運(yùn)動(dòng),使得鋼絲繩能在卷揚(yáng)機(jī)卷筒上整齊排列。利用這一機(jī)構(gòu) 進(jìn)行均勻排繩從而提高了鋼絲繩的使用壽命,從而提高了生產(chǎn)效率,降低了 勞動(dòng)強(qiáng)度。 關(guān)鍵詞: 起重設(shè)備, 卷筒, 排繩機(jī)構(gòu) ABSTRACT winch is a construction lifting equipment, because of its simple structure, manufacture low-cost, easy to operate, right operating environment adaptability, construction, industry, agriculture, shipping, transportation, chemical industry, metallurgy and oil sectors such as for lifting and dragging heavy objects, etc., as well as each building site, Each team works essential equipment. The construction site, hoist rope on the ropes around the tube system disorder often occur, then squeeze each other rope, wear serious, shorten the life of the wire rope; Meanwhile, the windlass wearing spacing devices-generally heavy hammer or screw. Mallets- installation maintenance inconvenience, screw-type arrangement as rope around disorder caused spacing failure. In order to overcome the above drawbacks, the hoist to attach a rope agencies. Pai brought the design to reduce speed gear boxes for the moment, the drive to make arrangements justice agencies reciprocating linear motion. can make rope winch drum, were neatly arranged. Use the bodies uniform rope so as to enhance the life of the wire rope, thereby increasing production efficiency, reduce labor intensity.
