The invention relates to an automatic anchor returning and aligning system of a port crane. The system comprises an automatic positioning mechanism, a control mechanism and a communication mechanism,and the automatic positioning mechanism and the control mechanism realize wireless communication through the communication mechanism. The automatic positioning mechanism comprises a photoelectric correlation switch mounted on an anchoring pin at a door leg, a FLAG plate mounted at the center position of an anchor pit, an absolute value encoder mounted on a driven wheel axle at the door leg and a control PLC mounted at the door leg. The control mechanism comprises a touch screen installed in a cab and a master control PLC installed in an electrical room. The communication mechanism comprises awireless signal transmitting end and a wireless signal receiving end which are arranged at the lower part and the upper part of a central slip ring of a central slip ring chamber. The automatic anchorreturning and aligning system of the port crane can assist a driver in returning to a designated anchoring position, accurate anchoring and aligning are automatically completed, and on the basis of improving the operation efficiency and accuracy, personnel investment and the labor intensity of the driver are further remarkably reduced.

    本发明涉及一种港口起重机自动回锚对位系统,其包括自动定位机构、操控机构、通信机构,自动定位机构与操控机构通过通信机构实现无线通信;其中,自动定位机构包括安装在门腿处锚定销上的光电对射开关、安装在锚定坑中心位置的FLAG板、安装在门腿处从动轮轮轴上的绝对值编码器、安装在门腿处的控制PLC;操控机构包括安装在司机室内的触摸屏和安装在电气房内的主控PLC;通信机构包括安装在中心滑环室的中线滑环处下、上两处的无线信号发射端和无线信号接收端。本港口起重机自动回锚对位系统能够辅助司机回到指定锚定位,并自动完成精确锚定对位,在提高了作业效率和准确率的基础上,还显著减少了人员投入和司机的劳动强度。
