[0002] Overhead transmission lines, especially ultra-high-voltage lines, have been in the wild for a long time. Foreign objects such as kites, plastic greenhouse tarpaulins, and plastic mulch that endanger the safety of transmission lines are often hung on the ultra-high-voltage lines. If they are not cleaned up in time, it will easily affect the normal power supply. delivery

At present, the removal of foreign objects suspended on overhead lines is mainly done manually, that is, the location of foreign objects is determined by visual inspection or observation with the help of telescopes, and then the staff work at heights to remove foreign objects; however, the above methods are labor intensive and dangerous for working at heights. High and low efficiency defects, it is difficult to achieve the desired result

At present, although there are intelligent robots that can walk on overhead lines and detect them in real time, at present, such robots cannot perform obstacle removal operations while crossing spacers and anti-vibration hammers on multiple wires such as 500kV overhead lines, that is, they cannot cross straight lines The pole tower greatly restricts the scope of the robot's obstacle removal, and the walking is extremely unstable and easy to fall, thus making it difficult to popularize and apply the existing obstacle removal robots, and most of them still use the method of manual removal

In addition, the mechanical arm and other mechanisms of the existing robot are installed on the outside, so that there are more forks on the outside of the whole robot, which greatly increases the difficulty of hoisting the robot on the overhead line

During the hanging process, it is very easy for the robot’s mechanical arm and other external components to wrap around the overhead wires, making the robot in a dilemma where it cannot be hung normally or removed. Once the above situation occurs, even if the staff is sent to climb the tower again It is also difficult to remove the robot through manual work. In the end, the robot can only be removed by cutting off the winding line with the robot, which will inevitably cause huge economic losses to the user.

In short, the main reason why the existing robots cannot achieve the desired effect is the lack of a stable and reliable walking device.
