An autonomous obstacle-crossing transmission line inspection vehicle and its working method

Abstract

The invention relates to an autonomous obstacle crossing type power transmission line patrol vehicle and a working method. The autonomous obstacle crossing type power transmission line patrol vehiclecomprises a vehicle body; a plurality of lifting mechanisms are mounted on the vehicle body; the lifting mechanisms are connected with lifting arms; the lifting arms comprises first lifting arm partsand second lifting arm parts; one ends of the first lifting arm parts are connected with the lifting mechanisms; the other ends of the first lifting arm parts are rotationally connected with one endsof the second lifting arm parts; the other ends of the second lifting arm parts are connected with walking wheels; the walking wheels are in contact with a power transmission line and connected with driving mechanisms; the driving mechanisms can drive the walking wheels to move along the power transmission line; the second lifting arm parts are in sliding connection with guide parts through guidegrooves; the guide grooves are obliquely arranged relative to the lifting direction of the lifting mechanisms; and a monitoring mechanism is mounted on the vehicle body. The patrol vehicle can effectively replace manual inspection, so that the inspection efficiency is high and the inspection effect is good.

Description

technical field [0001] The invention relates to the technical field of transmission line maintenance equipment, in particular to an autonomous obstacle-crossing transmission line inspection vehicle and a working method. Background technique [0002] At present, the transmission lines of many power systems are prone to damage under high-temperature and low-temperature weather conditions such as intense heat and severe cold. Due to the characteristics of large layout range, diverse power demands, and long line distances, transmission lines are vulnerable to wind, snow, heavy rain, etc. Under the influence of severe weather such as hail, or the impact of severe natural disasters such as mountain torrents, earthquakes, and landslides, the lines are likely to be damaged, which affects the operation and safety of the power system. [0003] The inventors have found that manual inspections are currently used for inspections of power transmission lines, requiring inspectors to work a...

Problems solved by technology

[0002] At present, the transmission lines of many power systems are prone to damage under high-temperature and low-temperature weather conditions such as intense heat and severe cold. Due to the characteristics of large layout range, diverse power demands, and long line distances, transmission lines are subject to strong winds, ice and snow, heavy rain, etc. Under the influence of severe weather such as hail, or the impact of severe natural disasters such as mountain torrents, earthquakes, and landslides, the lines are likely to be damaged, which affects the operation and safety of the power system

[0003] The inventors found that manual inspections are mainly used for inspections of power transmission lines at present, and inspection personnel are required to carry out high-altitude operations, which has high safety risks, and the inspection efficiency is low, and inspection dead ends are prone to occur
