1.5m3單軌抓斗起重機設計
摘要：起重機是一種作循環、間歇運動的機械。一個工作循環包括：取物裝置從取物地把物品提起，然后水平移動到指定地點降下物品，接著進行反向運動，使取物裝置返回原位，以便進行下一次循環。　　通常，起重機械由起升機構(使物品上下運動)、運行機構(使起重機械移動)、變幅機構和回轉機構(使物品作水平移動)，再加上金屬機構，動力裝置，操縱控制及必要的輔助裝置組合而成。　　在建橋工程中所用的起重機械，根據其構造和性能的不同，一般可分為輕小型起重設備、橋式類型起重機械和臂架類型起重機三大類。輕小型起重設備如：千斤頂、葫蘆、卷揚機等。橋架類型起重機械如梁式起重機、龍門起重機等。臂架類型起重機如固定式回轉起重機、塔式起重機、汽車起重機、輪胎、履帶起重機等。
關鍵詞：起重機、循環、裝置、動力裝置

Abstract: The derrick is a kind of machine that makes the circulation, intermittent sport A work includes circularly: Take the thing device from take the thing ground to bring up the product, then the level move to specify the location to decline product, carry on immediately after anti- to sport, make take the thing device to return the home position, in order to carry on next circulate.
    Usually, the derrick from rise to rise the organization  ( make product exercised up and down), circulate the organization( make the derrick move) and become an organization and turn round the organization( make the product make the level ambulation), and the metals organization, the motive equip, the assistance that manipulate the control and necessities equips to combine.
 In set up the bridge engineering the derrick use, construct according to it and the dissimilarity of the function, can is divided into a heavy equipments, the bridge type type derrick and a type of arm  derrick three major types generally. A heavy equipments such as: Jack, bottle gourd,   a  machine etc.. A  type  of  bridge  derrick ,such as beam type derrick, Dragon gate derrick etc.,. A type of arm derrick such as fix the type to turn round the derrick, tower type derrick, automobile derrick, tire, track derrick etc..
Key Words：derrick、circulation、machine、the motive equip
