2T 立柱式旋臂起重机的设计
摘要：
起重机是工程实际中广泛应用的特种设备。而旋臂起重机是近年发展起来的中小型起重装备，安全可靠，具备高效、节能、省时省力、灵活和结构独特等特点.根据旋臂起重机的整体结构特点和规范规定，了解起重机的发展现状、分析起重机的工作原理、系统组成、所要求实现的功能和相应的结构上必不可少的。该设计主要针对起升机构选择相应的零部件及技术参数，使其既能很好的实现起重机的运行还不互相干涉且配合良好，也对回转机构做了详细的分析介绍。传统设计的定柱式旋臂起重机，存在着结构笨重和刚度不足的缺陷，随着市场竞争激烈，对产品提出了更高的要求，采用现代设计对传统设计和计算方法技术提升，已迫在眉睫。

The Design Of 2-Ton Column Jib Crane
Abstract:
Crane is widely applied in engineering, Slewing crane is small and medium lifting equipment which developed in recent years,the characteristics of which are safe and reliable、 with high efficiency、 energy saving、time-saving、flexible 、unique structure,etc.According to the feature of completed structure for slewing jib crane and the rule of design.Understand the development of the crane’status、analyze its operation principle、system configuration、the function and relative structure that the crane required is indispensable.thus this paper put its emphasis on the design of main hoisting mechanism,choosing the appropriate spare parts and technical parameters for it in order to be good for crane operation and non-interference.the slewing mechanism analysis is introduced in detail too.the structure of crane designed with tradition method is overdesigned in strength and not enough in stiffness,and with fierce competition in the market a higher requirement for product has been brought forward.So using modern design technology to upgrade traditional design and calculation method is extremely urgent.
