High-bearing-capacity drilling rig slewing mechanism for coal mine drilling machine

A high-bearing drilling rig slewing mechanism for a coal mine drilling rig comprises a gyrator, one side of the gyrator is assembled on the drilling rig, the other side of the gyrator is used for being connected with a drill rod drilling rig, the gyrator is connected with the drilling rig through a slewing connecting disc, the gyrator is connected with the drill rod drilling rig through a slewing connecting disc, and each slewing connecting disc comprises a fixed disc and a fixed disc, the bolt is fixedly connected with a gyrator bolt; and the bearing boss is arranged at the center of the fixed disc, and the outer diameter of the bearing boss is matched with the inner diameter of a center hole in the corresponding side of the gyrator, so that the bearing boss is embedded into the center hole of the gyrator after the fixed disc is assembled on the gyrator. The connecting strength between the drill rod drilling frame and the gyrator is enhanced through the rotary connecting disc, and the safety problem caused b
