The invention relates to a split line moving platform. A power transmission lead is used as a working path in the platform, various barriers (a vibration damper, a crimping pipe, a spacing bar, a suspension line clamp, an insulator string and the like) are spanned and avoided, the platform is provided with a camera which can observe the condition of the running line and timely discover the defects of the line and hardware tools, and other working mechanical arms can be expanded to finish clearing line barriers and the like. A robot has flexible action and large working range, has the effect of protecting devices during jumping the barriers, and has high safety and reliability. The platform mainly consists of a traveling device, a driving arm device, an anti-tilting device and a power supply control box; and the traveling device is arranged on an electric cable and connected with the driving arm device, and the anti-tilting device is arranged at the tail end of the traveling device.
