Accurate positioning method for aluminum electrolysis multifunctional crown block

According to the accurate positioning method for the multifunctional crown block for aluminum electrolysis, movement mechanisms can be reduced, the movement inertia is greatly reduced, and accurate positioning can be achieved easily. According to the method for accurately positioning the multifunctional crown block for aluminum electrolysis, a group of XY plane movement system is additionally arranged on a trolley of the multifunctional crown block, a crust breaking mechanism, an anode replacing device and a slag salvaging mechanism on the multifunctional crown block are mounted on the XY plane movement system, and the XY plane movement system is matched with a group of closed-loop control driving system. And the XY plane moving system is driven to drive the crust breaking mechanism, the anode replacing device and the slag salvaging mechanism to accurately move to specified position coordinates in an XY plane. 一种实现铝电解多功能天车的精确定位方法，能够减少运动机构，大大减小运动惯量，有利于实现精确定位。这种实现铝电解多功能天车的精确定位方法，在多功能天车的小车上增加一组XY平面运动系统，将多功能天车上的打
