The invention relates to a four-bundle conductor traveling apparatus of a 500kV transmission line, which consists of main wheel traveling mechanisms, swing-bar elevation mechanisms, auxiliary wheel traveling mechanisms, brake mechanisms, boom side-swing mechanisms, a suspension basket and the like, wherein the main wheel traveling mechanisms, the swing-bar elevation mechanism, the auxiliary wheeltraveling mechanisms, the brake mechanisms and the boom side-swing mechanisms are respectively divided into two groups which are symmetrically distributed according to the traveling direction of the mechanisms with the left side and the right side being provided with one group respectively, and the main wheel traveling mechanisms, the swing-bar elevation mechanism, the auxiliary wheel traveling mechanisms, the brake mechanisms and the boom side-swing mechanisms are integrated into a whole by hinging two booms and a suspension basket bottom beam on the bottom parts of the main wheel traveling mechanisms. The four-bundle conductor traveling apparatus of the 500kV transmission line has high strength and a light weight, and the weight of the entire apparatus is greatly reduced; high-energy lithium battery is adopted as an electric power source, so the four-bundle conductor traveling apparatus can run continuously for more than one hour after being charged at one time; a direct-current low-speed brushless motor is adopted as a power mechanism, so the electrodeless variable-speed can be realized, and the four-bundle conductor traveling apparatus can be free and smooth to go forward and backward; the conductor traveling apparatus can successfully step across the barriers such as conductor spacers, stockbridge dampers, splicing sleeves, linear suspension strings and the like; and due to the adoption of the brake mechanisms, not only can the brake be realized, but also the safety effect can be realized.
