Description

Technical Field

[0001] The present invention relates to the technical field of live working equipment, and in particular to an insulating rod mechanical arm for live working using a ground potential method for power distribution. Background Art

[0002] In order to ensure the continuous and stable power supply of the power grid system, when performing live distribution operations, the ground potential operation method is usually used to perform live operations when the insulated boom truck cannot reach the site, and the line to be repaired is de-energized. In the above process, an insulated locking rod is usually used to fix the branch line drain wire before disconnecting the drain wire. However, most drain wires are vertically downward, and the existing locking rods are basically monkey head locking rods. The locking mouth and the drain wire angle cannot be locked in parallel, and the drain wire cannot be firmly locked or cannot be locked directly. During the process of disconnecting the drain wire, the drain wire is likely to become loose, causing a phase-to-phase short circuit, which poses a great safety hazard. At the same time, it also restricts the development of the ground potential operation method for disconnecting the drain wire operation project.

[0003] In addition, in the ground potential operation method, although the insulation blanket has a wide range of uses, great flexibility, and is made of soft materials, the existing insulation rod tools cannot wrap the insulation blanket around live equipment, making the laying of the insulation blanket difficult. Moreover, when the line is energized, the installation and removal of the hardware of the distribution line requires many special operating rods to complete the live installation and removal operations. The wide variety of tools increases the operational burden of the ground potential electrician. The lack of effective clamping tools in the operation of cleaning foreign objects from the wires means that the operators can only complete the cleaning work by picking, plucking, pulling, and winding the foreign objects. The operation is not only inefficient and laborious, but also creates a potential risk of phase-to-phase short circuit due to the phase-to-phase distance requirements of the live wires. Summary of the Invention

[0004] The present invention proposes an insulating rod robotic arm for live distribution operations using the ground potential method, which solves the problems encountered in the ground potential operation method, such as unreliable locking of drainage wires, difficulty in laying insulation blankets, lack of effective clamping tools in cleaning foreign objects from conductors, low cleaning efficiency and high risks.

[0010] Preferably, the wire clamp is composed of a left claw and a right claw, and the claw teeth of the left claw and the right claw engage with each other. The engagement of the claw teeth of the left claw and the right claw can prevent the wire from falling off.

[0011] Preferably, the inner edges of the claws are provided with a plurality of anti-slip patterns, which can increase the friction between the claws and the objects, thereby preventing the claws from slipping when grasping objects, causing the objects to fall off and other safety accidents.

The wireless chip is arranged in the handle. The handle can be rotated and pushed up and down. When the handle is rotated, the upper rotating arm realizes the rotation function, thereby driving the wire clamp to rotate 360°. When pushed in the upward and downward directions, the second electric push rod realizes up and down movement, thereby driving the wire clamp to open and close. After performing the above operations, the handle can be automatically reset; the switch can be pushed up and down to realize the up and down movement of the first electric push rod, thereby adjusting the angle between the wire clamp and the fixed seat, and automatically reset after the operation is completed.
