Power transmission line live work robot and its online and offline control method

Abstract

The invention discloses a power transmission line live work robot and its online and offline control method. The robot comprises a case body and a control unit arranged inside the case body. The upper part of the case body is provided with a pair of conductive wire walking wheels. The two sides of the case body are provided with a wire supporting device. The upper surface of the case body at two sides of the supporting devices is provided with upper penetration holes. The lower surface of the case body is provided with lower penetration holes arranged correspondingly along the vertical direction of the upper penetration holes. The two sides of the case body are both provided with insulation cords. The two ends of the insulation cords penetrate one upper penetration hole on the same side of the case body and extend out of the lower penetration hole at its lower side, and one end of each insulation cord is clamped or fixed at the lower penetration hole. Between the conductive walking wheels and the case body, a traction motor is arranged. The conductive waling wheels, the wire support device, and the traction motor are connected respectively with the control unit. The online and offline control method comprises the utilization of an electric coil rolling machine to control the insulation cords to realize the rise and fall of the robot. According to the invention, it is possible to realize the online and offline of a live work robot, and the online and offline procedures are reduced. Highly automatic, the robot and the method achieve good stability.

Description

technical field [0001] The invention relates to a live working robot for a power transmission line, in particular to a live working robot for a power transmission line and a control method for going on and off the line. Background technique [0002] The distribution of overhead transmission lines has the characteristics of wide area, complex terrain, and harsh natural environment. Power lines and tower accessories have been exposed to the wild for a long time, and are subject to continuous mechanical tension, electrical flashover, and insulation aging, resulting in broken strands, wear, and corrosion. If it is not repaired and replaced in time, it will lead to serious accidents and large-scale power outages, which will cause great economic losses and serious social impacts. Therefore, regular inspections must be carried out on overhead transmission lines to discover and eliminate hidden dangers in time, prevent accidents, and ensure power supply safety. At present, in the f...

Problems solved by technology

However, there are usually two methods for getting on and off the live working robot at present: using manual work to realize the going on and off of the live working robot. , the disadvantage of high risk; use the ladder truck to lift the staff and the live working robot to the vicinity of the power transmission line, and the staff place or remove the robot

Because many transmission lines are erected on complex geographical conditions such as high mountains, it is often difficult to reach the bulky aerial ladder trucks, and this work must be performed in the event of a power outage, resulting in huge economic losses

Therefore, this method has the limitation of geographical conditions
