Design Study on Dynamic Monitoring System of Coal Mine Hoist Tension
Taking JKMD-5 ×4P type hoist as the object,the tension dynamic monitoring system of hoist rope is designed in combination with the actual situation.The system hardware mainly includes all kinds of sensors,signal transmission devices,host computer,etc.On the basis of the hardware,the software program design is carried out to achieve the accurate detection of the tension of four wire ropes of the hoist,analyse the tension imbalance between the ropes,and control the tension within a safe range of 10％.The load of cage A and B can be detected to ensure that there is no overloading,and the counterweight imbalance of the two cages can be monitored at the same time.The system is applied to the hoist engineering practice,through 12 months of practical operation,the system is found to achieve the expected results.
