[0003] With the rapid development of social economy, the construction of power grid has also reached an unprecedented speed. Due to the concentrated and explosive construction of transmission lines, the trees in the line protection area have not been felled in time, and the number of trees to be felled has increased significantly, which greatly increases the discharge of lines to trees. probability, which poses a serious threat to the safe and stable operation of the line
To timely report the hidden dangers of trees in the line protection area, and to cut down trees in time has become an important task for the maintenance company's transmission and transportation inspection. However, when cutting tall trees in the line protection area, it is often encountered that the direction of tree dumping cannot be controlled. , the fallen trees will touch the live wires, causing casualties and equipment damage. Secondly, when the maintenance personnel tie ropes on the trees to control the direction of the trees falling, it is easy for people to fall down the trees and cause casualties. ACCIDENT

Abstract
The invention discloses a tree cutting-down tool for cutting down a tree below a wire. The tree cutting-down tool for cutting down the tree below the wire comprises a hook body, a hinge pin, an insulating control rod and an insulating rope, wherein a small hole is formed in the position, close to the tail, of the hook body, and the hook body is hinged to the insulating control rod through the hinge pin; the tail of the hook body is provided with a through hole used for tying of the insulating rope, and one end of the insulating rope is tied in the through hole. The tree cutting-down tool for cutting down the tree below the wire has the advantages that the principle and the structure are simple, the practicability is high, a good control function is achieved, the tree cutting-down tool can be used by a worker on the side near to electricity through an insulating tree cutting-down hook, the application range is wide, when the tree is cut down, the worker controls the special tree cutting-down hook on the ground to fix the tree so that the falling direction of the tree can be controlled, and the situation that the corresponding worker falls when climbing on the tree to tie the rope is avoided. When the tree is fixed through the tree cutting hook, the working state can be adjusted under the control of the insulating rope, the working efficiency can be improved easily, the time period during which the wire is powered off for treatment is shortened to a great extent, operation is easy, and the tree cutting-down tool is firm, durable and high in stability.
Description
technical field [0001] The invention relates to the field of tree felling tools, in particular to a tree felling tool for cutting down trees under wires. Background technique [0002] With the acceleration of the power grid construction process, the transmission line actively implements the "non-stop power supply" power supply strategy, and the power supply without power supply will get the trend of power supply in the future. The felling hook for professional tree felling can ensure the non-power-off strategy of the line to the greatest extent, and has good practicability. It can cut down the trees below the line without power-off, and the cost is not too high, which can better improve Reliability and safety of power supply, saving lines for scientific and safe operation. [0003] With the rapid development of social economy, the construction of power grid has also reached an unprecedented speed. Due to the concentrated and explosive construction of transmission lines, the...
