矿用提升机制动力检测研究

Study of brake force detection for mining hoist

通过对提升系统的动力学分析,提出了检测缠绕式矿用提升机制动力和总变位质量的原理和方法.在提升机低速等速运行时,对提升机进行安全制动,同时测量出提升距离和制动减速度,从而间接地计算出提升机的制动力和总的变位质量,为提升机的制动力和总变位质量的测量提供了新的方法.

By the means of dynamic analysis of the hoisting system,this paper proposes a detection principle and method of total equivalent mass and brake force for mining hoist.When the mining hoist runs at a low speed and reaches the uniform speed,it uses the safety break,meanwhile it measures the elevating distance and the braking deceleration simultaneously.Thus,it can indirectly measures the hoist braking force and the total displacement quality,which has provided a new approach for the measurement of the mining hoist’s break force and the total displacement quality.
