一种新型自动纠偏装置在门式起重机上的应用

摘要

Through the analysis of the project used in correcting scheme has control precision problem, based on the design of a sensor and PLC automatic deviation - correcting device, based on the sensor and PLC technology of new automatic correction device applied in large span gantry crane, realizes the automatic correcting and automatic reset, the industrial computer technology, human - computer interface and sensor technology perfect combination together, make the correction precision higher and more reliable, solves the large span and large lifting height deviation, crane rail gnawing phenomenon, realize the crane to automatically adjust the support legs at two sides of the running state and the real time monitorinm%通过分析工程中经常采用的纠偏方案存在的控制精度问题,设计了一种基于传感器和PLC的自动纠偏装置,这种基于传感器和PLC技术的新型自动纠偏装置应用于大跨度门式起重机,实现了自动纠偏和自动复位,将工控机技术、人机界面和传感器技术完美地结合到一起,使纠偏精度更高更可靠,解决了大跨度和大起升高度起重机跑偏、啃轨现象,实现起重机自动调整两侧支腿运行状态和实时监控。
