Pipeline cable threading robot dog

The utility model relates to a pipeline cable threading robot dog which comprises a machine shell, an adaptive structure is arranged outside the machine shell, a power structure is arranged outside the machine shell, the adaptive structure comprises a first motor, the bottom of the first motor is fixedly connected with the inner bottom wall of the machine shell, and the bottom of the first motor is fixedly connected with the inner bottom wall of the machine shell. An output shaft of the first motor is fixedly connected with two worms through couplings, one ends of the worms penetrate through and extend to the outside of the output shaft, and two mounting shells are fixedly mounted on the left side and the right side of the machine shell correspondingly. According to the pipeline cable threading robot dog, by arranging the adaptive structure, the purpose of increasing the friction force of the contact surface of the robot dog and a pipeline is achieved, wheels of the robot dog are prevented from idling, the th
