The ground wire clamp is simple in clamping operation and reliable in ground connection structure.
In order to achieve the above purpose, the present invention adopts the following technical scheme:
an apparatus for live installation of a ground clip for a distribution network line, comprising:

The U-shaped locking piece 1.8 is provided with a sliding groove which is in sliding connection with the supporting ring 1.2.
If the lower mounting platform 2 is not completely lowered to the ground, the weight of the whole mounting robot is large, and at the moment, if an operator continuously lifts the upper hanging mechanism 1 through the insulating rod to take down, the operator needs to bear the gravity of the whole mounting robot, the requirement on the operator is increased, the insulating rod is easy to slip in the taking down process, the lower mounting platform 2 is hung below the upper hanging mechanism 1 for a long distance, shaking easily occurs, and the possibility of errors of the operator is further increased. The U-shaped locking piece 1.8 can enable the U-shaped locking piece 1.8 to block the opening structure 1.4 of the supporting ring 1.2 through the gravity of the lower mounting platform 2 before the lower mounting platform 2 is not completely lowered onto the ground, at the moment, even if an operator wants to take down the upper hanging mechanism 1, misoperation is avoided, the U-shaped locking piece 1.8 is lowered due to the gravity, only when the lower mounting platform 2 is in contact with the ground, the U-shaped locking piece 1.8 is lifted under the action of the third spring, the U-shaped locking piece 1.8 does not block the opening structure 1.4 of the supporting ring 1.2, at the moment, the operator can take down the upper hanging mechanism 1 through the opening structure 1.4, and the whole process only needs to bear the gravity of the upper hanging mechanism 1, so that the labor intensity is lowered, the possibility of operation errors is reduced, and the lower mounting platform 2 can be prevented from being broken. The U-shaped locking piece 1.8 and the locking sliding block 1.5 form double insurance, and the structure is simple.
