Rotor hoisting monitoring device

The utility model belongs to the technical field of monitoring equipment. The utility model relates to a rotor hoisting monitoring device. The rotor is characterized in that the rotor comprises six grooves which are arranged on the rotor, and every two grooves are spaced by 60 degrees; the square tubes are respectively arranged in the grooves; the infrared distance sensor groups are respectively arranged at the bottoms of the square tubes; the two reinforcing steel bars are used for fixing the square tube and the groove; the spring and the infrared distance sensor set comprise three infrared distance sensors which are vertically arranged in a three-dimensional mode, infrared rays of two infrared distance sensors penetrate through the end face of the square tube to be emitted to the front and back opposite directions, and infrared rays of the other infrared distance sensor are vertically emitted to the ground. According to the utility model, the sensors are used for measuring or positioning the central positio
