A metamorphic crawling mechanism insulator detection robot capable of translational cutting

Abstract

The present invention provides an insulator detection robot with a metamorphic crawling mechanism that can translate and cut into, including a mobile unit and a detection element, and three groups of the mobile units are connected to each other as a whole to form a mobile mechanism that surrounds the insulator string; a rectangular frame There is a metamorphic crawling mechanism on the side. The metamorphic crawling mechanism is equipped with a driving device and claws. The rectangular frame is equipped with a synchronous belt-type guide locking mechanism, which can be disassembled and assembled. The synchronous belt-type guide locking mechanism and the insulator string are flexible Contact to avoid wear on the insulator surface during the guiding process. The crawling claw can achieve complete translation of cutting into and exiting the edge of the insulator, without meshing friction with the insulator surface, and does not damage the surface coating of the insulator. At the same time, because the crawling claw is equivalent to a cone-shaped butt joint with the edge of the insulator when cutting in, it has good error tolerance for the insulator string, overcomes the stuck phenomenon that occurs when the rotary meshing crawler mechanism has poor tolerance for error, and effectively ensures the stability of the mechanism's operation process.

technical field [0001] The invention belongs to the technical field of insulator detection, and in particular relates to an insulator detection robot with a metamorphic crawling mechanism capable of translational cutting. Background technique [0002] The insulator is a special insulation control that can play an important role in overhead transmission lines, and its safe operation directly determines the stability of the power system. At present, my country's economy is growing rapidly, and industry and agriculture are developing rapidly. At the same time, people's living standards are constantly improving. Ultra-high voltage and ultra-high voltage transmission systems have been widely used. The construction and maintenance of power grids have received more and more attention.

AI Technical Summary

Problems solved by technology

The use of insulator strings will be exposed to the outside air for a long time due to its particularity, which will cause it to be affected by various factors, such as wind, sun, rain, temperature changes, etc. After suffering from these hazards, the resistance of the insulator will decrease. reduce, resulting in cracking or even breakdown and other adverse conditions, and then complete failure

Therefore, it is necessary to detect the insulator strings in operation to avoid short circuit and breakdown of the insulators, so as to ensure the safe and reliable operation of the transmission line, and avoid affecting the overall operation of the power system and causing huge economic losses.

[0003] The traditional way to detect insulators in China is manual operation. The operator holds the detection equipment and climbs up the tower to detect the operation status of all insulators one by one. Manually detect one by one, the labor intensity of the operator is high, the risk is high, and the efficiency is low; secondly, it cannot be measured quantitatively, and the accuracy of the measurement results is greatly affected by environmental factors and human factors

However, the commonly used robots generally have some common shortcomings, such as: complex structure, cannot be disassembled, is not conducive to operators to carry and install, and cannot effectively adapt to the detection environment of insulators; The surface of the insulator is in rolling contact, and the plate-shaped guiding mechanism is in rigid contact with the insulator during the guiding process. When the walking device uses crawling claws, the movement of the crawling claws is not completely translational, and meshing friction occurs between the insulators, which will damage the insulators. wear on the surface; additionally, manual recovery is required after the insulator has been inspected
