摘要
为了改善矿井提升机的制动性能,设计了基于PLC+PC的提升机制动系统,建立了该系统的数学模型,模拟出不同载荷和几种工况下的制动减速度和制动时间。结果表明:该系统的制动减速度随工况变化,能改善制动性能;减少制动时间,提高提升机的运行效率;通过控制减速度的大小可减少制动过程钢丝绳的振动,提高提升机运行的稳定性和安全性。该研究对于改善矿井提升机制动性能、提高提升效率具有重要意义和参考价值。
In order to improve a braking performance of a mine elevator, a mine elevator braking system is designed based on PLC ＋ PC. Math- ematical models of the system are established. Braking decelerations and braking time under different loads and several working conditions are simulated. Results show that the braking deceleration of the system changes with loads and working conditions, with the braking performance improved, the braking time reduced correspondingly, the operation efficiency of the elevator increased, meanwhile, the vibration of the wire rope during braking reduced through controlling the magnitude of the speed. So that the stability and the safety of elevator operation are im- proved,which have important significance and reference values for improving the braking performance and the elevating efficiency of a mine elevator.
