Overhead high-voltage power transmission line strain clamp drainage plate bolt tightening robot

Abstract

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.

Description

technical field [0001] The invention relates to a high-altitude live working robot, in particular to a robot for fastening bolts of tension clamps and diversion plates of overhead high-voltage transmission lines. Background technique [0002] The working environment of overhead high-voltage transmission lines is relatively harsh. Due to the perennial exposure to the wild, it is very vulnerable to environmental and geographical factors. Some factors such as icing, breeze vibration and other factors will cause the wire to vibrate, which in turn will lead to the loosening of the bolts of the strain clamp drainage plate. In this way, the resistance will increase due to inaccurate contact. Once the resistance increases, the temperature of the drain plate will rise accordingly, and the oxidation of the contact surface will be strengthened. As the temperature continues to increase, the drain plate will be burned. If there is a disconnection accident, it will have a great impact on...

Problems solved by technology

A typical example is the Quebec Hydropower Research Institute in Canada, which has successfully developed an inspection and maintenance robot with the function of overcoming obstacles. The robot uses a single arm to carry a bolt fastening device for maintenance operations. The connection between the bolt fastening device and the bolt mainly relies on The self-adaption of the device itself is not outstanding, and it can only output a certain torsional moment when adjusting the articulated working arm. Therefore, the bolt fastening device has certain limitations in practical use.
