运用达朗贝尔振动原理分析了提升钢丝绳更换时天轮与绞车滚筒之间的弦绳段提升钢丝绳振动规律,并给出了振动方程,为研究提升钢丝绳更换时振动安全稳定性分析提供了理论支撑。针对相关“跳绳”事故案例,深入分析了发生事故的根源所在,并给出了相应的应对措施;分析结果表明:换绳时旧绳的大幅抖动、不合格的换绳工具等都会对弦绳段提升钢丝绳产生不利的外部激励,并引发“跳绳事故”;适当降低换绳速度一定程度上可以控制不合格换绳工具带来的不利影响。 The principle of vibration of hoisting ropes between the sheave and the winch drum is analyzed by using the principle of the Dalambel vibration, and the vibration equation is given, which provides a theoretical support for the study on the analysis of vibration safety and stability during wire rope replacement . According to the related case of “skipping rope” accident, the root cause of the accident is analyzed in depth, and the corresponding countermeasures are given. The analysis results show that the sharp jitter of the old rope and unqualified rope changing tools will change Chord rope hoisting rope to produce adverse external incentives, and trigger “rope accident ”; appropriate to reduce the rope speed to a certain extent, you can control the adverse effects of rope replacement tools.
