A split-and-hanging wire-type walking clamping mechanism for transmission line inspection robots

Abstract

A split-hanging wire-type walking clamping mechanism for a power transmission line inspection robot. Driven walking wheels are respectively provided on the front and rear sides of the active walking wheel to realize the walking mode of bilateral support to reduce the lateral offset; the active walking wheel The driving wheel and the driven wheel are respectively installed on the supporting column, and the two columns can move toward each other or relative to each other along a straight line, so that the driving wheel and the driven wheel can be switched between the staggered state and the split open state. The staggered state is used for Walking, the split open state is used to hang the line or overcome obstacles; there is a clamping assembly between the pillars below the active traveling wheel and the driven traveling wheel. The clamping assemblies are two sets and include clamping rollers, roller brackets, bracket guides Rod and clamping screw, the clamping roller is located at the top of the bracket, the bracket guide rod and the clamping screw are mounted on the bracket in parallel, the two clamping screws rotate in opposite directions and the ends adopt a plug-in structure, two sets of roller brackets They can be moved toward or relative to each other along the respective clamping screw to clamp or loosen the transmission line.

Description

technical field [0001] The invention belongs to the technical field of power transmission line inspection robots, and in particular relates to a split-line hanging type walking and clamping mechanism for a power transmission line inspection robot. Background technique [0002] As an indispensable part of modern society, power system, especially the stability and safety of transmission lines, is an important guarantee condition for power supply. Among them, high-voltage transmission lines, as an important part of power transportation, are exposed to the external environment for a long time, and are prone to problems such as line wear, aging, and broken strands, thus causing obstacles to power transmission. Therefore, it is very necessary to conduct regular inspections on transmission lines. However, due to the special distribution and erection environment of high-voltage transmission lines, it has become increasingly difficult to rely on manual inspection methods to meet the...

AI Technical Summary

Problems solved by technology

However, since there are a large number of fittings installed on the power transmission line to ensure the safety of the line, the line inspection robot must cross these fittings to complete the inspection. However, the existing line inspection robots with the ability to overcome obstacles generally use unilateral walking wheels. The supported walking mode is prone to lateral deviation during the walking process of the inspection robot, and the obstacle surmounting method adopted by the inspection robot is relatively complicated.
