Overhead line inspection robot and inspection method

Abstract

The invention discloses an overhead line inspection robot and an inspection method. The overhead line inspection robot comprises a control box, an inspection mechanism mounted on the control box and a walking mechanism, wherein the walking mechanism comprises at least two mechanical arm assemblies, each mechanical arm assembly comprises a mechanical arm base, a first joint module, a second joint module, a first mechanical arm, a third joint module, a second mechanical arm and a fourth joint module which are connected in sequence, a walking wheel and a pressing wheel which are arranged up and down are arranged on each second mechanical arm, and tensioning mechanisms are arranged on the second mechanical arms and used for achieving tensioning control over the pressing wheels and the walking wheels. According to the overhead line inspection robot, multiple obstacle-crossing modes are provided through control over the four-degree-of-freedom mechanical arms and the walking tensioning mechanisms, meanwhile, the self-adaptive process can be achieved according to different road sections, the turning and climbing abilities are strong, the protection grade is high, and the robot has the advantages of being simple in structure, low in cost, long in service life and the like.

Description

technical field [0001] The invention relates to the technical field of inspection of overhead transmission lines, in particular to an inspection robot and inspection method for overhead lines. Background technique [0002] With the sharp increase in demand for electricity in modern society, the total mileage of transmission lines in my country has reached 1.59 million kilometers. The inspection and maintenance of these lines has become a major problem for the power grid. At present, the inspection methods for overhead transmission lines mainly include: [0003] 1) Manual detection by telescope: This method is labor-intensive, it is difficult to detect subtle faults, and the detection accuracy is low. When the transmission line crosses mountains, rivers, lakes and dense forests and other areas that are difficult for personnel to reach, the inspection work cannot be carried out. [0004] 2) Helicopter aerial survey: Considering the safe distance between the helicopter and the ...
