为提高工效，构件在翻身、起吊过程中，多采用一次绑扎连续作业，某些刚度较弱的构件，为满足在翻身、起吊等阶段的强度和抗裂度要求，吊索上还要加设滑轮，这就带来了空中稳定平衡的问题。本文根据钢索在绕滑轮滑动时，构件所有可能位置中，位能最小的平衡位置，方为稳定平衡 In order to improve the work efficiency, the components are used for continuous operation in one operation during the process of turning over and lifting. Some of the components with weaker stiffness are required to be installed on slings in order to meet the requirements for strength and crack resistance during the stages of turning and lifting. Pulleys, which brings stability and balance in the air. This article is based on the equilibrium position of the minimum potential energy in all possible positions of the component when the cable is sliding around the pulley.
