Abstract

The invention relates to a tool for maintaining power transmission lines, and particularly relates to a special hook rod for electric power maintenance. The hook rod comprises a hook head and an insulating rod, wherein the hook head comprises claws and a hook handle; each claw comprises a circular-arc-shaped bending portion and a linear hook neck, the curvature radius of the same bending portion is identical, and the claw is fixedly connected with the hook handle through the hook neck; one end of the hook handle is fixedly connected with one end of the insulating rod; the number of the claws is 2-4, and the curvature radiuses of the bending portions of any two of the claws are different. The special hook rod provided by the invention has the beneficial effects that the hook rod is provided with 2-4 claws which are different in size, thereby being capable of adapting to branches with different sizes, good in hooking and pulling effect, and convenient to use.

Description

technical field [0001] The invention relates to a tool for maintenance of power transmission lines, in particular to a special hook rod for power maintenance. Background technique [0002] Tree branches near transmission lines and power equipment and facilities can easily cause equipment short-circuit, and may also break wires, damage equipment, and cause power supply interruption. Therefore, timely cleaning of tree branches near transmission lines and power equipment and facilities is an important part of transmission line maintenance. . Since the branches that need to be pruned are generally at a higher position, transmission line maintenance personnel use insulating hook rods to hook the branches to a safe location and then trim them. However, the thickness of the branches is different, if the size of the hook is too large or too small, it will affect the effect of hooking the branches, and temporarily replacing the hook will affect the work efficiency. [0003] The com...
