Power transmission line inspection robot

Abstract

The invention relates to a power transmission line inspection robot which comprises a U-shaped support, moving wheels and anti-falling devices. Baffles are arranged at the front side and the rear side of each anti-falling device, each anti-falling device comprises two concave plates with opposite notches, a power transmission line is arranged between the two concave plates, and a limiting wheel is arranged in each concave plate. A baffle is arranged at the lower sides of the concave plates, and anobstacle makes contact with the baffle. Along with movement of the device, the obstacle pushes the baffle to swing backwards, and meanwhile, under the transmission action of a worm and a worm wheel, a winding wheel rotates to wind a pull rope, and an anti-falling device is pulled to rotate upwards around a power transmission line, so that the distance between the lower sides of the two concave plates of the anti-falling device is increased, space is vacated for the obstacles, and the obstacles can be conveniently passed.

Description

technical field [0001] The invention belongs to the technical field of line inspection robots, and in particular relates to a power transmission line inspection robot. Background technique [0002] The transmission line is an extremely important part of the power system. In order to ensure its safe and stable operation, regular inspections are required. At present, the main methods used are manual inspections, helicopter inspections and inspection machines. The efficiency of manual inspections is low. , the labor intensity is high, the risk is high, the dangerous forest and cliff lines cannot be carried out, and the inspection of the line is limited, while the inspection cost of the inspection helicopter is high, and the inspection quality is easily affected by the climate. In case of windy weather, it will affect the operation difficulty of drones. Inspection robots can not only reduce the intensity of manual labor, but also improve the quality and efficiency of inspection ...

[0002] The transmission line is an extremely important part of the power system. In order to ensure its safe and stable operation, regular inspections are required. At present, the main methods used are manual inspections, helicopter inspections and inspection machines. The efficiency of manual inspections is low. , the labor intensity is high, the risk is high, the dangerous forest and cliff lines cannot be carried out, and the inspection of the line is limited, while the inspection cost of the inspection helicopter is high, and the inspection quality is easily affected by the climate. In case of windy weather, it will affect the operation difficulty of drones. Inspection robots can not only reduce the intensity of manual labor, but also improve the quality and efficiency of inspection operations, ensure the safe operation of transmission lines, and improve the automation of power grids. level matters

[0003] Due to the existence of many obstacles on the transmission line, such as anti-vibration hammers and spacers, it is required that the inspection robot can not only walk quickly along the transmission line, but also have a certain ability to overcome obstacles. Chinese patent 201410195445. The obstacle-surpassing mechanical arm of the inspection robot adopts a parallelogram structure to realize the obstacle-surmounting of the walking arm. Although the V-shaped walking wheels are used to clamp the transmission line during normal walking, when the traveling mechanism crosses obstacles, the traveling mechanism and the transmission line Separation leads to detachment from the transmission line, and in severe cases, the device may even fall off and be destroyed; Chinese patent 201710535142.1 discloses a composite clamping device and a cable inspection robot used by a cable inspection robot. The movable plate can be driven by a screw nut and a motor , the clamping arm is connected to the movable plate through the spring group (static force balance part), the clamping arm can move with the movable plate, the clamping arm can actively drive the movable plate to clamp through the motor, and cross obstacles In the process, it is also to adjust the clamping distance to cross obstacles, and the asymmetrically set wheels are likely to cause local deformation of the vibration of the transmission line, thereby increasing the risk of the robot falling
