description The utility model relates to the technical field of petroleum drilling, in particular to a drilling top drive balancing device. A well drilling top drive balancing device comprises a lifting ring and a balancing oil cylinder. The lifting ring comprises a connecting column and stand columns connected to the two ends of the connecting column, the stand columns are sleeved with limiting rings, and the limiting rings are connected with the outer side walls of the stand columns. The balance oil cylinder is connected with the two stand columns through hoops, the hoops are arranged on the stand columns in a sleeving mode, and the bottom ends of the hoops abut against the top ends of the limiting rings. The bottom end of the balance oil cylinder can be connected with the top end of the top drive gearbox. Due to the fact that the limiting ring is arranged on the stand column of the lifting ring, the clamping hoop is arranged on the stand column in a sleeved mode, and the bottom end of the clamping hoop abuts against t
