为了实现双驱动刮板输送机运行过程中两电机功率的智能协调控制,平衡两端链轮啮入点和啮出点的动张力,分别测试和提取刮板输送机运行时两端电机的电流信号,采用应变片测试刮板啮入和啮出链轮时的动张力,通过模糊PID变频调速方法对电机转速进行智能调节控制,实现机尾电机对机头电机驱动力的有效补偿,保证两端电机功率以及链轮张力差值的平衡。通过实验测试结果表明:刮板输送机智能协调控制系统可有效地实现两端电机的功率平衡调节,两端链轮的张力差值基本保持一致,为提高刮板输送机的工作效率和延长其使用寿命提供了一种重要的技术手段。
In order to realize the intelligent coordinated control of the power of the two motors during the operation of the double-drive scraper conveyor, the dynamic tension of the meshing points and the meshing points of both end sprockets is balanced, and the currents of the motors at both ends of the scraper conveyor are respectively tested and extracted Signal, using the strain gauges to test the dynamic tension when the scraper engages and spins out the sprocket, and intelligently adjusts and controls the motor speed through the fuzzy PID frequency conversion speed regulation method, so as to effectively compensate the driving force of the tail motor to the head motor, The balance between the motor power at both ends and the difference in sprocket tension. The experimental results show that the scraper conveyor intelligent coordinated control system can effectively balance the power of both ends of the motor, and the difference of tension between the two ends of the sprocket is basically the same. In order to improve the working efficiency and extend the scraper conveyor Service life provides an important technical means.
