Gap bridge device for power transmission line inspection robot

The utility model discloses a gap bridge device for a power transmission line inspection robot, which comprises two ground wires connected to two sides of a strain tower, and a gap bridge track connected between the two ground wires on the outer side of the strain tower. The two ends of the gap bridge track are connected with two ground wires through two track transfer devices respectively, the two ends of each track transfer device are in transition connection with the ground wires and the gap bridge track respectively, and the width of the middle of each track transfer device in the horizontal direction is larger than that of the two ends of the track transfer device in the horizontal direction. And the gap bridge track is connected with the strain tower through a suspension device. According to the utility model, the rail transfer devices are arranged at the ground wires at the two sides of the strain tower, and the two rail transfer devices are connected through the gap bridge rail, so that the inspection
