A cable twisting-releasing and surface cleaning movable trolley comprises a horizontal frame, wherein travelling wheels are arranged at the bottom of the horizontal frame; a motor speed reducer, a supporting frame and positioning-parking mechanisms are sequentially arranged on the horizontal frame from back to front; the supporting frame is rotationally connected with a rotating shaft arranged in the left-right horizontal direction, a cable reel is fixedly and coaxially arranged on the rotating shaft, and one end of the rotating shaft is in transmission connection with a power output shaft of the motor speed reducer; the two positioning-parking mechanisms are arranged in a bilateral symmetry manner, a portal frame is arranged between the tops of the two positioning-parking mechanisms, and the portal frame is provided with a sliding type cleaning device used for cleaning a cable. The cable twisting-releasing and surface cleaning movable trolley is novel in design, cable twisting-releasing and cleaning are integrally set, an electric mode is adopted for both twisting and releasing of the cable, the labor intensity of workers is relieved, working efficiency is improved, no extra power is required for cleaning, the effect of cleaning soil on the surface of the cable is good, and it is ensured that the cable wound to the cable reel is arranged in order.
