The invention discloses an automatic walking positioning method for a bridge crane trolley in a large hydropower station workshop. The automatic walking positioning method comprises the steps that a crane working area is divided into X, Y and Z directions; an operation instruction is input to enable the bridge crane trolley to walk towards a target position, speed regulation control is achieved for acceleration and deceleration in the walking process through a fuzzy control strategy, and the walking position is detected in real time in the walking process and fed back to a position control system; after reaching a reasonable position, the walking mechanism starts to decelerate to enter a crawling speed area, at the moment, an operator is responsible for parking, and finally accurate positioning of the walking mechanism is completed. Accurate position data of operation of the bridge crane are automatically collected, monitored and analyzed, swinging of a heavy object in the hoisting process is effectively reduced, the working efficiency of the bridge crane is improved, and positioning of the bridge crane is facilitated.

    本发明公开了一种大型水电站厂房桥机小车行走自动定位方法包括:把起重机工作区域划分为X、Y、Z三个方向;输入操作指令使桥机大小车向目标位置行走,行走过程的加速与减速均通过模糊控制策略实现调速控制,行走过程中实时检测行走位置并反馈至位置控制系统;行走机构到达合理位置后开始减速进入爬行速度区域,此时由操作者负责停车,最终完成行走机构的准确定位。实现自动采集、监测,分析桥机运行的准确位置数据,有效减少重物在吊装过程中的摇摆,有助于提高桥机的工作效率,有助于桥机实现定位。
