Transmission line inspection robot obstacle walking device

Abstract

The invention discloses a transmission line inspection robot obstacle-crossing device. The transmission line inspection robot obstacle-crossing device comprises three mechanical arms and a movable frame used for supporting the mechanical arms. Every mechanical arm comprises a mechanical arm support fixedly arranged on the movable frame, a traveling driving mechanism for driving traveling, a braking mechanism for controlling stopping, inverted-lug slider mechanisms for preventing shedding and a palm opening-closing mechanism for crossing obstacles are arranged on the mechanical arm support, the bottom end of the palm opening-closing mechanism is fixedly arranged on the mechanical arm support, the traveling driving mechanism is arranged at the top end of the palm opening-closing mechanism, the braking mechanism is arranged in the middle of the palm opening-closing mechanism below the traveling driving mechanism, and the inverted-lug slider mechanisms are arranged on two sides of the palm opening-closing mechanism. The transmission line inspection robot obstacle-crossing device is capable of achieving routine inspection as well as obstacle-crossing inspection of power transmission lines, so that power transmission line inspection precision and accuracy are improved, and a guarantee is provided for safety operation of the power transmission lines.

Description

technical field [0001] The invention relates to the technical field of inspection of transmission lines in electric power systems, in particular to a device capable of walking along transmission lines and completing inspections. Background technique [0002] In the power system, the use of high-voltage and ultra-high-voltage overhead power lines is the main way of long-distance transmission and distribution of power. However, due to the long-term exposure of power lines and tower accessories in the wild, they have been affected by continuous mechanical tension, electrical flashover, and material aging for a long time, resulting in damage such as broken strands, wear, and corrosion. It may expand, and eventually lead to serious accidents, resulting in large-scale power outages and huge economic losses. Therefore, the power company needs to regularly inspect the line equipment to detect early damage and defects and evaluate them, and then arrange necessary maintenance and rep...

Problems solved by technology

[0003] At present, there are mainly three methods for inspection of transmission lines: 1) Manual visual inspection method: use the naked eye or telescope to observe the power lines in the jurisdiction. Manual inspection is still the most important inspection method in China; although it has a strong However, due to the wide distribution of transmission lines and complex geographical conditions, inspection workers need to cross mountains and ridges, wading across rivers for inspection

This method has high labor intensity, low work efficiency and detection accuracy, and poor reliability.

2) Aerial survey method: control the helicopter to fly along the power transmission line, and the staff observe and record the abnormal points along the line with naked eyes or airborne camera equipment; although this method is close to the distance, it improves the detection efficiency and accuracy, but the power line Passing quickly from the field of view of observers or recording equipment increases technical difficulty and high operating costs
