摘要
对临时护顶机的伸缩式主臂的设计计算方法进行了探讨。结合伸缩式主臂的结构特点,进行受力分析,尤其对搭接部分与非搭接部分的强度进行了分析与计算。
In this paper,the calculating method of telescope booms on temporary roof protecting machine is proposed, the calculating formula of telescope boom's strength, analyzing mechanics force combining structure characteristic of telescope boom. Especially analyzing and calculating of superposition section and non-superposition section.
