The invention provides an overhead high-
voltage power transmission line strain clamp drainage plate bolt tightening
robot. The
robot comprises a body, an inspection
robot platform, a first working arm and a second working arm. The inspection robot platform comprises two fixed arms which are arranged at two sides of the body in a reverse symmetry manner at a
fixed interval, each fixed arm is provided with a traveling part and a line clamping part, the traveling part is used for traveling along a wire line, the line clamping part is used for clamping the wire line and achieving positioning, and one side of the line clamping part is provided with an
equipotential part which is used for making the robot and the wire line remain
equipotential. The first working arm is arranged at a first side of the front end of the body, and the
tail end of the first working arm is provided with a nut-screwing device. The second working arm is arranged at a second side, of the body, being opposite to the first side, and the
tail end of the second working arm is provided with a bolt positioner. The robot can position bolts and tighten nuts, and is simple in abutting joint operations and high in efficiency, and can replace manual operation, and is safe and reliable, and is simple to operate.
