Abstract
The invention relates to a tree pruning tool for a line protective area, which belongs to the tree pruning tool field. The tree pruning tool for the line protective area comprises a pair of hydraulic scissors, a hydraulic system and a movable trolley, and is characterized in that the hydraulic system consisting of a hydraulic jack and a pedal is fixed on the movable trolley, the hydraulic jack is connected with an oil cylinder of the hydraulic scissors through an oil pipe, and a fixed bracket of the hydraulic scissors is provided with one to four sections of handheld insulation rods. By adopting the movable trolley, the tree pruning tool is convenient to transport to a work site, so that the handling procedure can be reduced, and the time and labor can be saved; the tool can prune big tree branches, so that a maintainable range of the line protective area is larger, and trees are pruned to be more tidy; and by adopting a plurality of handheld insulation rods, high voltage can be isolated, an electric shock can be prevented, the handheld insulation rods can be assembled or disassembled according to a working condition, so that the tree pruning tool is applicable to different trees in different heights. Through further improvement, and by utilizing the tree pruning tool, the workload and the labor intensity of workers can be alleviated, the tree pruning tool is applicable to different trees in different heights, and the safety running of a power line can be guaranteed.
Description
technical field [0001] The invention provides a tree pruning tool in a line protection area, which belongs to the field of tree pruning tools among power supply line maintenance tools. Background technique [0002] At present, the country vigorously advocates afforestation, and is now carrying out forest siege. The number of trees in the line protection area has increased a lot, and the line operation management unit has to spend a lot of manpower to prune the trees in the protection area every year. The traditional tree pruning method is to use a long pole with an iron hook to prune smaller trees. For larger trees, the staff use ladders, foot buckles and other climbing tools to climb the trees, and then use hand saws, axes or chainsaws. to trim. Because some trees are too close to the wires, when people go up the trees to trim them, they need to cut off the power of the lines in advance, which not only affects the normal electricity consumption of users, but also affects ...
