Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings for the convenience of the skilled person.

As shown in fig. 1-2, the ground-mounted/dismounted distribution network grounding wire tool comprises a hook 1, an electroscope 2, a brake pull rod 3, a fixed pulley 4, a grounding wire 6 connected with a grounding rod 5, an insulating rod 12 and a sleeve 11.

The brake pull rod 3 is selected and adjusted according to the height of the distribution network line, so that the condition that an operator stands on the ground and can touch the line with the top of the brake pull rod 3 is met.

The hook 1 is made of conductive metal materials, the hook 1 and the electroscope 2 are fixed on the rod head of the brake pull rod 3, and the electroscope 2 is electrically connected with the hook 1. Electroscope 2 has audible and visual alarm device, through touching the gauze with couple 1, can judge whether the gauze is discharged and is accomplished according to electroscope 2 sends out the police dispatch newspaper. Further, the head of the brake lever 3 may be provided with a conductive metal, and the conductive metal may be electrically connected to the electroscope 2.

The fixed pulley 4 is fixed on the upper part of the brake pull rod 3, the grounding wire 6 is fastened with the grounding rod 5, the grounding wire 6 passes around the fixed pulley 4, the tail ends of the grounding rod 5 and the grounding wire 6 are respectively arranged at two ends of the fixed pulley 4, and the grounding rod 5 can be lifted by pulling the grounding wire 6.

As a preferred technical scheme, the bottom of the brake pull rod 3 is provided with a universal insertion rod barrel. The universal inserted link barrel comprises a conical barrel 7, an inserted link 8, a pedal rod 9 and two fixing rings 10. The fixing rings 10 are symmetrically fixed at the small end of the conical barrel 7, and the pedal rod 9 penetrates through the two fixing rings 10 and is rotatably fixed with the fixing rings 10, so that the pedal rod 9 can rotate around the fixing rings 10 at will, and further the conical barrel 7 can rotate around the pedal rod 9 at will. The inserted bar 8 is perpendicular to the pedal bar 9 and is fixedly connected with the pedal bar 9 in a rotatable manner (the connection mode can be that a connecting hole with the inner diameter slightly larger than the outer diameter of the inserted bar 8 is formed in the pedal bar 9, the inserted bar 8 is inserted into the connecting hole, and limit bolts are sleeved at two ends of the connecting hole). The insertion rod 8 and the pedal rod 9 can be connected in a rotatable manner, so that the conical cylinder 7 can be rotated freely in the horizontal direction.
