Driving force adjusting device and track inspection robot

The invention relates to the technical field of automatic inspection equipment, in particular to a driving force adjusting device and a track inspection robot, the driving force adjusting device comprises a supporting frame, a driving assembly and at least one driving adjusting assembly, the driving assembly is mounted on the supporting frame and used for driving the supporting frame to move relative to a guide rail, and the driving adjusting assembly is mounted on the supporting frame. The first end of the driving adjusting assembly is connected with the supporting frame, the second end of the driving adjusting assembly abuts against the driving assembly, the driving adjusting assembly can move relative to the supporting frame, and then the output torque of the driving assembly is adjusted. Therefore, the transmission connection mode of the driving assembly is changed, the output torque of the driving assembly can be adjusted, and the technical problem that the advancing speed of an existing inspection track
