A track type wall-climbing four-freedom degree parallel robot comprises a tracked vehicle and a four-freedom degree parallel robot body; the tracked vehicle comprises a rectangular chassis, four sleeves and two permanent magnet track mechanisms, wherein the sleeves are uniformly distributed on the chassis and are fixedly connected to the chassis, and the permanent magnet track mechanisms are symmetrically connected to the chassis and drive the chassis to crawl along a magnetic wall; the four-freedom degree parallel robot body comprises a moving platform, four SPR type branches of the same structure, two connecting rods and four magnetic plates; the SPR type branches comprise cylinder bodies and piston rods, each connecting rod penetrates through parallel through holes in the moving platform, the two ends of each connecting rod are connected to rotation pairs at the upper ends of the cylinder bodies of two branches, the lower ends of the piston rods are connected to spherical pairs on the magnetic plates, and the magnetic plates are in slide fit with the sleeves. The track type wall-climbing four-freedom degree parallel robot has the advantages that the attraction force is large, the motion is flexible, the structure is simple, control is easy, and the moving platform can carry tools for repairing large equipment and work-piece defects.
