Robot for inspection of overhead high-voltage power transmission line

Abstract

The invention discloses a robot for inspection of an overhead high-voltage power transmission line. A small rotation disc and a large rotation disc are installed on a telescoping mechanism, a front arm is installed on the small rotation disc, a supporting plate support is installed on the large rotation disc, and a middle arm and a rear arm which have the same structure are installed on the supporting plate support; the front arm, the middle arm and the rear arm are linearly arranged and are used for line walking, the front arm drives the rear arm and the middle arm to advance, the front arm, the middle arm and the rear arm are arranged in the shape of T and are used for line barrier crossing, and the front arm, the middle arm and the rear arm advance alternatively; the front arm comprises a front support, an elevating block, an elevating table connected with the elevating block, a driving wheel assembly arranged on the elevating table, and a compaction wheel assembly disposed below the driving wheel assembly and above a wire, and a space for clamping the wire is formed between the compaction wheel assembly and the driving wheel block; and the middle arm comprises a driven wheel arranged on a middle arm support and a brake mechanism in front of the driven wheel. The robot provided by the invention is compact in structure, light in weight, low in energy consumption and high in interchangeability, and can walk and cross barriers on a single-strand wire.

Description

technical field [0001] The invention relates to the technical field of robots, in particular to a robot used for inspection of overhead high-voltage transmission lines. Background technique [0002] High-voltage transmission line is one of the important facilities of the power system, and it is also the "artery" of national infrastructure construction and social development. Its safe operation directly affects my country's economic development and the establishment of infrastructure. However, due to the impact of long-term wind and sun, natural disasters, external factors such as bird damage and man-made damage, the high-voltage lines are damaged to varying degrees. If they are not discovered and eliminated in time, it will cause immeasurable consequences. . Therefore, in order to ensure the safe and stable operation of the transmission line, it is necessary to carry out regular inspections on the transmission line. [0003] The usual inspection methods include manual insp...

Problems solved by technology

[0003] The usual inspection methods include manual inspection, aerial survey method and the just-started inspection robot. Manual inspection is time-consuming and laborious, and there are also potential safety hazards; aerial survey method cannot conduct close-up inspections of line towers, and at the same time, affected by the weather, the operating procedures are cumbersome , which leads to high operating costs and is difficult to be promoted; the inspection robot walks on the wire or the ground wire by the robot, and patrols the high-voltage transmission line at a close distance by adding a series of equipment to the robot body, and the inspection robot works live , crawling along the high-voltage transmission line at a certain speed, and can cross obstacles such as shock-proof hammers, strain-resistant clamps, suspension clamps, pole towers, etc. Implement short-distance detection, and then replace workers to conduct power line inspections, effectively improve the efficiency and accuracy of inspection operations, ensure the quality of line maintenance, reduce operation and maintenance costs, take into account economic and social benefits, and adapt to the needs of the market. It has a broad prospect and is a hot spot in the research of high-voltage line inspection technology in recent years.

However, so far, due to the high requirements on the robot body and the difficulty in design, it has not been produced in real production, and the designed inspection robot has the following deficiencies:

[0004] The structure is complex, the weight is heavy, the multi-joints consume a lot of energy, and it is difficult to control obstacles, and the corner tower cannot overcome obstacles, which will cause great damage to high-voltage lines, and it remains in the laboratory stage without large-scale production
