Obstacle removing and repairing robot for underground cable pipeline

The invention discloses an obstacle removing and repairing robot for an underground cable pipeline. The tunneling end of the robot is defined as the front end, and the other end of the robot is defined as the tail end; the robot comprises a front-section machine shell, a universal jacking and supporting unit and a rear-section machine shell, and the two axial ends of the universal jacking and supporting unit elastically support the inner wall of the cable pipeline in the radial direction and are axially and fixedly connected with the front-section machine shell and the rear-section machine shell correspondingly. The front end of the front-section machine shell is connected with a cutting unit in an axial telescopic adjusting mode. The front end of the rear-section machine shell stretches out and draws back in the radial direction and is connected with a drilling positioning unit in an adjusting mode, and the tail end of the rear-section machine shell is coaxially and rotationally connected with a spiral pushi
