单梁桥式起重机的设计

单梁桥式起重机的设计(含毕业论文说明书23000字,开题报告,文献翻译,中期检查报告,cad图纸6张)
摘 要   
我做的毕业设计课题是单梁桥式起重机设计。单梁桥式起重机是一种轻型起重设备，它适用起重量为1～20 吨，适用跨度4.5～16.5米，工作环境温度在≥-35。C与≤+35。C范围内，适合于车间、仓库、露天堆场等处的物品装卸工作。桥架由一根主梁和两根端梁刚接组成。根据起重量和跨度，主梁采用普通工字钢和U形槽组合焊接形成。主梁和端梁之间采用承载突缘普通螺栓法兰连接。提升机构采用CD型电葫芦。
    此次设计的主要内容有：问题的提出、总体方案的构思，结构设计及对未知问题的探索和解决方案的初步设计，装配图、零件图等一系列图纸的设计与绘制，以及毕业设计说明书的完成。

关键词 ：起重机；桥式起重机；大车运行机构；小车运行结构；小车起升；结构桥架；主端梁 。

ABSTRACT
The topic of my graduation design is list the beam bridge type derrick of design the list beam bridge type derrick is a kind of light heavy equipments, it start to apply the weight as 1~20 tons, apply to across degree 4.5~16.5 meters, the work environment temperature is in the ≥ -35.C and ≤ +35.Inside scope, suitable for car, warehouse, open-air heap field etc. of the product pack to unload a work. The bridge was carried beam by a lord beam and 2 to just connect to constitute. According to weight with across a degree, lord beam adoption common the work word steel and U form slot combination weld formation. Lord beam and carry an of beam an adoption loading To good luck common stud bolt method orchid conjunction. Promote the organization adoption CD type an electricity bottle gourd.
