Pruning system for automatic pruning robot for overhead power transmission lines

Abstract

The invention discloses a pruning system of an automatic branch pruning robot for an overhead transmission line.The pruning system comprises a first blade and a second blade which are arranged up and down in the horizontal direction and a pruning robot arm driving mechanism for driving the first blade and the second blade to reversely rotate.A cutting edge of the first blade corresponds to a cutting edge of the second blade.In the work process, the first blade and the second blade reversely rotate to form scissors to prune branches, whether the branches are soft or hard, the branches are attacked from two sides and are broken once pruned, the branches can be effectively clipped, and pruning efficiency is high.The first blade and the second blade rotate reversely, reaction torque of the first blade and reaction torque of the second blade can offset, and therefore the overhead transmission line cannot be influenced by torque force brought by the first blade and the second blade.

Description

technical field [0001] The invention relates to the field of channel maintenance for overhead transmission lines, in particular to a pruning system for a branch pruning robot used for live work on overhead transmission lines. Background technique [0002] With the continuous development of urban and rural industry and agriculture, behaviors that endanger the safe operation of transmission lines such as new tree planting in transmission line channels will continue to appear. The maintenance of line channels in the power sector will still face severe challenges. The contradiction between forestry and electricity has always been the biggest hidden danger to the safe and reliable operation of transmission lines. It is more and more protruding, which brings great hidden dangers to the safe and stable operation of transmission lines. [0003] As the density of the power grid increases year by year, the contradiction between tree lines has become increasingly prominent. The direct...

Problems solved by technology

[0005] 1. The coordination of the villagers is difficult: the villagers ask for high compensation, which makes coordination difficult. Some villagers refuse to accept the coordination for their own selfishness, regardless of the safety of their lives and the power grid. Lines, they all arrogantly obstructed the power department from cutting down offline trees, and asked for high prices and high compensation

[0006] 2. The cost of compensation is high: ranging from tens to thousands of yuan per tree

[0007] 3. The safety of personnel is not guaranteed: Some branches are close to the transmission line, and the safety distance is not enough. Without power failure, the safety of personnel cannot be guaranteed; there are often hornet's nests in the woods, and once they are alarmed, there will be heavy casualties ACCIDENT

[0008] 4. It is very difficult to cut down: many places cannot be reached by cloak cars, and manual felling is very difficult

[0013] 1. If the branches are thin and soft, the chainsaw or chainsaw will brush the branches forward and cannot effectively cut the branches

[0014] 2. If the branches are thick and hard, there is no protective measure for the chainsaw or chainsaw, and blindly sawing forward will easily cause damage to the chainsaw or chainsaw, and even damage other parts of the pruning robot.

[0015] 3. The feed speed of chainsaw or chainsaw has certain limitations when pruning branches, and the pruning efficiency is low

[0016] 4. When the chainsaw or chainsaw works, it moves in one direction, and the overhead transmission line is easily affected by the torque force brought by the chainsaw or chainsaw.
