纠偏检测控制技术在起重机上的应用

本文分析桥门式起重机大车运行机构啃轨的原因,提出运用纠偏检测控制技术。结合先进的PLC控制和变频调试技术、PID控制器以及现场总线通讯技术等,取代传统的电气控制方式,减少桥门式起重机中大车的啃轨现象,提高设备的安全使用性能,减少设备的故障率,降低维护成本和维修工作量,同时操作简单、运行可靠,具有节能等效果。

This paper analyzed the reasons of rail gnawing for gantry crane traveling mechanism, proposed using the correct test control technology. Combined with the advanced PLC control and frequency conversion technology, PID controller and field bus communication technology, the methods replaced the traditional electrical control, reduced the rail gnawing phenomenon of crane bridge gantry crane in use, improved safety performance of the equipment, reduced the equipment failure rate, the cost of maintenance and repair work, also had the advantages of simple operation, reliable running with energy-saving effect.
