摘　　要：提出在国产汽车起重机上加装作业平台和控制装置构成大高度高空作业车的设计方案。以三菱公司FX-2N型可编程控制器(P LC)为控制核心,以液压缸为执行元件,以角度传感器为反馈元件,以触摸屏为人机对话窗口,设计了一种高空作业平台电液调平控制系统,可实现自动调平、远程操控及状态报警等功能。介绍该调平系统的组成、原理及控制方法,给出系统的软、硬件设计框图。在河北清远电厂60 m高储煤球罐建设施工中的实际使用情况表明,该调平控制系统效果良好。It is to put forth a design concept to add a work platform with its own control apparatus to the local-made auto-cranes for a higher reach.The concept placed MITSUBISHI'S FX-2N PLC as a kernel for control,hydraulic cylinders as actuating units,angular sensors as feed-back units,and touch screens as the dialog box,to have designed an electro-hydraulic leveling control system there-for which can realize such functions as auto leveling,remote control,and put up warning in state.Further introduction includes composition of the leveling system,working principles and control methods,by giving frame-work diagrams for software and hardware design.A prototype of the system has been practically used in a 60 m height ball type tank for coal storage as located in Qingyuan Power Plant,Hebei Province,with better results to indicate its broad prospect in application.
