一种低姿态岸边集装箱起重机大梁平移精确控制方法

A Precise Control Method of Low-profile Quayside Container Crane Girder Translation

介绍了一种新式低姿态岸边集装箱起重机的大梁平移精确控制方法。为克服大梁钢丝绳过于松弛对大梁平移的不良影响,在平移过程中使用编码器实时校准大梁位置,在大梁接近指定位置时及时减速,应用微动程序使大梁找到停止位置,并采用感应限位最终确认是否平移到位。经过多次反复试验,确认该方法能够使大梁准确快速地平移到指定位置。

A new precise control method of low-profile quayside container crane girder translation is introduced.In order to overcome the adverse effects of the loose rope on the translation of the girder,the encoder is used to calibrate the girder position during the translation.The girder decelerates in time when the girder approaches the designated position.The dynamic program is applied to make the girder find the stop position,and the induction limit is used to finally confirm whether the translation is in place.After repeated tests,it is confirmed that this method can make the beam move to the specified position accurately and quickly.
