*学院*届毕业设计说明书定柱式悬臂起重机结构设计与分析摘要：定柱式悬臂起重机是由立柱、回转臂、悬臂驱动装置和电动葫芦组成。立柱下端底座通过地脚螺栓固定在混凝土基础上，由电机带动减速机驱动装置使悬臂回转，电动葫芦在悬臂工字钢上作往返运行作业。它的特点有：自重轻，悬臂长，起重量大，安装、操作、维修简单。它们完全独立，是一种理想的工作岗位起重机，并适用于室外的货场和装卸平台。定柱占地面积小。对于起升净空非常小的情况下也能获得最大的起升高度。本设计从整体设计出发，依次设计计算了2t定柱式悬臂起重机的悬臂和立柱的主要机构部件。选取了螺栓，开式齿轮等主要零部件。设计了符合要求的悬臂结构，并校核了轴承，焊缝强度和转动轴键的强度和刚度等力学性能参数。在设计过程中，运用优化设计的方法，使各个结构尽量达到最合理的布置和选择。关键词:定柱式悬臂起重机金属结构columncantilevercranesstructure design and analysisAbstract: Slewing cantilever crane is a column, rotating arm, cantilever drive and the composition of electric hoist. Column bottom of the base fixed to the concrete foundation by anchor bolts on the gear driven by the motor drives the cantilever rotary, electric hoist for the cantilever-beam on the run from job . Its characteristics are: light weight, arm length, lifting capacity, installation, operation and maintenance simple. They are completely independent, is an ideal job cranes, and applies to the outdoor yard and loading platforms. Set column small footprint. For lifting the case of very small clearance can get the Maximum lifting height.At the beginning of this design of main mechanism of 0.8t in the column cantilever crane cantilever and the column component calculation.The main parts such as bolts, open gear. Designed to meet the requirements of the cantilever structure, and check the bearing, weld strength and the rotating shaft to bond strength and stiffness and other mechanical properties. In the design process, using the method of optimal design, the structure to achieve the most rea
