Rotating mechanism of shot blasting machine

The utility model discloses a rotating mechanism of a shot blasting machine. The rotating mechanism comprises a lifting hook, a guide rail and a universal joint, wherein the universal joint is arranged in the middle of the guide rail and perpendicular to the guide rail, and the lifting hook is arranged at the lower end of the universal joint. The rotating mechanism is characterized in that the universal joint comprises two transmission components and a fixed seat, the two transmission components are sheathed together and axially fixed in the fixed seat, and the two transmission components can rotate in the fixed seat by 360 degrees. Through the mode, according to the rotating mechanism of the shot blasting machine, the universal joint can be bent toward any angle, therefore, the rotating mechanism of the shot blasting machine can realize that the lifting hook is under the state of being perpendicular to the guide rail in the climbing process of the shot blasting machine, without the need of using a guide need
