Control method for rotor turning device, computer program product, computer readable storage medium, control device, and rotor turning system

A control method for a rotor turning device, a computer program product, a computer readable storage medium, a control device, and a rotor turning system. The rotor turning device comprises at least two turning units (50); a movable end of a telescoping cylinder (51) in each turning unit (50) is provided with a pin body (53); the pin body (53) is releasably secured on a rotor (28). The control method comprises: dividing the at least two turning units (50) into two groups; first removing pin bodies (53) of a first group of turning units (50) from the rotor (28), and then re-securing the pin bodies (53) at another positions on the rotor (28), wherein pin bodies (53) of a second group of turning units (50) are fixedly connected with the rotor (28) in the process of removing and re-securing the pin bodies (53) of the first group of turning units (50); and after the pin bodies (53) of all the turning units (50) are re-secured, changing the state of the telescoping cylinders (51) of all the turning units (50), and driving the rotor (28) to turn relative to a machine base (27). In this way, all the turning units (50) in the turning device are sequentially unlocked, moved to a next working station, and re-locked on the rotor (28). In the whole process, there are always some pin bodies (53) locked on the rotor (28), thereby avoiding uncontrollable turning of the rotor (28), and improving the pushing efficiency of the turning units (50) while ensuring the safety in the turning process of the rotor (28).
