为了解决多绳提升机钢丝绳张力不平衡调整不准确的问题,分析了影响钢丝绳张力不平衡的主要因素,设计了基于非均匀弦振波法的钢丝绳张力不平衡故障诊断方法,建立了钢丝绳蠕动量的计算模型和钢丝绳蠕动量差异值的计算模型,提出了考虑钢丝绳蠕动时的绳槽半径差异值的计算方法。通过现场试验表明,该方法能够准确反映出绳槽半径的差异,从而为钢丝绳张力不平衡的调整提供了可靠依据。
In order to solve the problem of inaccurate adjustment of tension unbalance of wire rope in multi-hoist hoist, the main factors that affect unbalanced tension of wire rope are analyzed. A method to diagnose unbalanced tension of wire rope based on non-uniform string vibration method is designed. And calculation model of creep difference of wire rope, a calculation method of rope radius difference considering wire rope creep was put forward. The field test shows that this method can accurately reflect the difference of the rope groove radius, and thus provides a reliable basis for adjusting the tension imbalance of the steel wire rope.
