The invention relates to special automatic walking equipment for treating the inner wall of a diesel oil pipeline. The special automatic walking equipment comprises two inner wall automatic walking branched chains, wherein four connecting reinforced columns are symmetrically connected between the two inner wall automatic walking branched chains and have a function of connecting and fixedly supporting the two inner wall automatic walking branched chains, besides, two telescopic walking branched chains are symmetrically mounted at the lower end of each inner wall automatic walking branched chain, the equipment automatically walks to the inner wall of the pipeline through the four telescopic walking branched chains, the four telescopic walking branched chains stretch outwards after the equipment walks to the inner wall of the pipeline, at the moment, the two inner wall automatic walking branched chains stretch outwards until being tightly attached to the inner wall of the pipeline, and the equipment can stably walk on the inner wall of the pipeline through the two inner wall automatic walking branched chains; each inner wall automatic walking branched chain comprises a square support block. According to the special automatic walking equipment for treating the inner wall of the diesel oil pipeline, the function of stable automatic walking on the inner wall of the diesel oil pipeline can be realized, and the conditions of rollover and vertical vibration possibly produced in a walking process are eliminated.
