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。 关键词：起重机；起升机构；回转机构
