1.5m3单轨抓斗起重机设计
摘要：起重机是一种作循环、间歇运动的机械。一个工作循环包括：取物装置从取物地把物品提起，然后水平移动到指定地点降下物品，接着进行反向运动，使取物装置返回原位，以便进行下一次循环。　　通常，起重机械由起升机构(使物品上下运动)、运行机构(使起重机械移动)、变幅机构和回转机构(使物品作水平移动)，再加上金属机构，动力装置，操纵控制及必要的辅助装置组合而成。　　在建桥工程中所用的起重机械，根据其构造和性能的不同，一般可分为轻小型起重设备、桥式类型起重机械和臂架类型起重机三大类。轻小型起重设备如：千斤顶、葫芦、卷扬机等。桥架类型起重机械如梁式起重机、龙门起重机等。臂架类型起重机如固定式回转起重机、塔式起重机、汽车起重机、轮胎、履带起重机等。

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
