摘要
介绍了起重机起升机构中平衡臂装置的作用、组成、工作原理及使用条件,指出单倍率起升机构上常用的平衡臂装置结构形式中存在的不足,并提出了改进方案,介绍了一种平衡臂装置的特点和结构。以某钢厂起重机采用的该平衡臂装置为例,论述了主要受力件的受力状况和设计过程,指出了设计中需要注意的问题。
The paper introduces the action, composition, working principle, and using condition of the balance ann device in crane's hoisting mechanism; puts forward the deficiencies existing in common structural types of the balance arm device, and improvement plan; presents the feature and structure of a balance arm device. With the balance arm device ap- plied in cranes in certain steel factory, the paper details the load conditions and design process of major load-carrying parts and points out the problems to be concerned.
