主梁三维装配图
摘要
起重机械是一种循环、间歇运动的机械。常用于物品的装卸。经过这些年得发展，桥式起重机在现代生产活动中已一个不可取代的地位。随着时代的进步，起重机的自动化程度也逐步提高，从原始的用人和牲畜控制到了现代的机器控制。因此工厂对起重机的要求也是逐渐提高。起重机正面临着一场改革变化。
起重机一般指既有起升机构又有水平运动机构的起重设施，这些机构均是起重机基本的机械结构。我们一般根据其不同的水平运动形式，将起重机分为桥式起重机和臂架式旋转起重机。本次设计中我选用的是桥式起重机。
根据设计要求，本次设计主要是一个满足5T承载量的钢体结构，主要设计计算端梁、主梁的尺寸，并对其进行校核，端梁与主梁之间采用法兰式螺栓连接，并对缓冲器进行了选择和校核。文章后面还对焊接工艺进行了选择和分析。最终完善CAD工程图以及三维图，使其在实际生产操作中能够准确稳定的完成各项工作，提高生产效率，并成功投入到市常

ABSTRACT
Lifting machinery is a circulating, intermittent movement of machinery. Commonly used in the loading and unloading of items. After these years of development, bridge cranes have an irreplaceable position in modern production activities. With the progress in these years, the degree of automation of the crane has been gradually improved, from the original employment and livestock control to the modern machine control. So the factory requirements for the crane is gradually increased. The crane is facing a reform and change.
Cranes generally refer to hoisting facilities with both lifting and horizontal movements, which are the basic mechanical structures of the crane. We generally divide cranes into bridge cranes and boom-type rotary cranes according to their different levels of movement.
According to the design requirement, This design mainly for a steel structure satisfy 5T load, and determine the size of crane girder and main beam. The size also need to be check and calculate. Bolt connection is used between girder and main beam. And I also choose the buffer, calculate and check whether it meet the design requirements. Finally, the welding process is designed and analyzed. CAD drawing and the graphic being finished, make it accurate and stable in actual production operations to complete the work, improve productivity, and finally being successfully brought on to the market.
Keywords: Single bridge crane；main beam; end beam; flanged coupling
