基于PLC的摩擦提升机滑动监测及制动措施

Sliding Monitoring and Spare Anti-sliding Braking for a Friction Hoist Based on a PLC

针对摩擦提升机易发生滑动故障,介绍了基于 PLC 的摩擦提升机的滑动监测以及防滑后备措施。给出了判断危险滑动和安全滑动的方法。在发生危险滑动后采取的基于PLC 闭环控制的制动措施以及制动机构设计。

Aimed at the fault of sliding easily occurring for a friction hoist, this paper introduces a sliding monitoring and spare anti-dangerous-sliding method based on PLC. The method to judge dangerous sliding and safety sliding is presented and as well it is offered that the braking measure of PLC-based closed-loop control and the design of the braking mechanism in case of dangerous sliding happening.
