A winding hoist is a key equipment for ultra-deep mine hoisting. The inter-circle transition in the winding process of the hoisting wire rope causes vibration, impact, extrusion, wear, and other negative phenomena, which seriously affect the service life of the rope. In order to explore the effect of inter-circle transition on the friction and wear performance of wire ropes, the present study adopts the principle of equal ratio scaling to build a test rig for an inter-circle transition of wire ropes, and the evolutions of coefficient of friction and maximum friction temperature with increasing the tensioning force and rope speed under dry friction were investigated by the test rig, and the major wear mechanisms under different working conditions were investigated in combination with the wear morphologies. The results show that the coefficient of friction decreases first and then increases with an increase in the tensioning force, and decreases linearly with increasing the rope speed. The evolution of maximum temperature over time under different tensioning forces and rope speeds are all mainly divided into three stages: The rapid growth phase, the slow growth phase, and the stable phase. The influence of the rope speed on the temperature of the wire rope is greater than that of the tensioning force. Moreover, in the process of inter-circle transition, the major wear mechanism is abrasive wear. Furthermore, larger tensioning force and rope speed may cause the steel wires on the contact surface of the wire rope to break.

干摩擦下环行过渡过程中多层缠绕葫芦用钢丝绳的摩擦磨损特性研究

卷扬机是超深矿井提升的关键设备。提升钢丝绳的缠绕过程中的圆周间过渡会导致振动,冲击,挤压,磨损和其他负面现象,从而严重影响钢丝绳的使用寿命。为了探索圆环过渡对钢丝绳的摩擦磨损性能的影响,本研究采用等比例缩放原理,为钢丝绳的圆环过渡及其演化过程建立了试验平台。通过试验装置研究了在干摩擦条件下,摩擦系数和最大摩擦温度随张紧力和绳速的增加而增加的情况,并结合磨损形态研究了在不同工作条件下的主要磨损机理。结果表明,摩擦系数随着张紧力的增大先减小,然后增大,并随着绳速的增大而线性减小。在不同的张紧力和绳速下,最高温度随时间的变化主要分为三个阶段:快速生长阶段,缓慢生长阶段和稳定阶段。绳索速度对钢丝绳温度的影响大于张紧力的影响。而且,在圆间过渡过程中,主要的磨损机理是磨料磨损。此外,较大的张紧力和绳索速度可能导致钢丝绳的接触表面上的钢丝断裂。并随着绳速的增加而线性减小。在不同的张紧力和绳速下,最高温度随时间的变化主要分为三个阶段:快速生长阶段,缓慢生长阶段和稳定阶段。绳索速度对钢丝绳温度的影响大于张紧力的影响。而且,在圆间过渡过程中,主要的磨损机理是磨料磨损。此外,较大的张紧力和绳索速度可能导致钢丝绳的接触表面上的钢丝断裂。并随着绳速的增加而线性减小。在不同的张紧力和绳速下,最高温度随时间的变化主要分为三个阶段:快速生长阶段,缓慢生长阶段和稳定阶段。绳索速度对钢丝绳温度的影响大于张紧力的影响。而且,在圆间过渡过程中,主要的磨损机理是磨料磨损。此外,较大的张紧力和绳索速度可能导致钢丝绳的接触表面上的钢丝断裂。绳索速度对钢丝绳温度的影响大于张紧力的影响。而且,在圆间过渡过程中,主要的磨损机理是磨料磨损。此外,较大的张紧力和绳索速度可能导致钢丝绳的接触表面上的钢丝断裂。绳索速度对钢丝绳温度的影响大于张紧力的影响。而且,在圆间过渡过程中,主要的磨损机理是磨料磨损。此外,较大的张紧力和绳索速度可能导致钢丝绳的接触表面上的钢丝断裂。
