Description

Universal ground wire operating lever

technical field

The utility model relates to a universal grounding wire operating rod, which belongs to a maintenance tool in the electric power industry. the

Background technique

During the construction and maintenance of transmission lines, power outages, power inspections, and suspension of grounding wires are required in accordance with the "Electricity Safety Work Regulations". , erection on the same pole, etc., which makes it extremely inconvenient to hang the grounding wire. The current situation is as follows: (A) The traditional grounding wire operating rod is composed of an insulating rod and a head hook. The hook part and the insulating rod are directly fixed together, and the head hook The part cannot be rotated, the ground rod cannot be bent, and it is extremely inconvenient to operate when the ground wire is suspended. (B) The current method of hanging the grounding wire. When the grounding wire is suspended in the current operation, because the wire is parallel to the ground and is in a horizontal position, the insulating operating rod and the hook are fixed together. When the grounding wire is hung, the operator's body should fly away from the tower and straighten Only the arm can be hooked. Since the ground soft copper wire has a certain weight after the arm is straightened, it is a test for the physical strength of the operator. If there is a little carelessness, the operating rod is very easy to drop. (C) The method of removing the grounding wire. When the work is completed, the operator should lie on a stable place and stretch out due to the influence of the length of the insulator, the opening of the pole, and the cross arm. It can only be removed with a straight arm. Sometimes because the hook is perpendicular to the ground and the operator is in an improper position, it is very difficult to remove. the

To sum up, it can be seen that the grounding wire operating rod used in the operation of the existing transmission line, its insulating rod and suspension head are straight rod fixed, especially when it is located on a tension rod or a multi-layer line, the root of the receiving rod is opened, Influenced by the length and width of the cross-arm, insulator strings, etc., it is extremely inconvenient to use in actual operation, and when picking up the ground wire, the operator can easily touch the ground wire, causing certain potential safety hazards. the

Detailed ways

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations. the

The front in the embodiment is subject to the direction indicated by the arrow in the drawings. As shown in Figures 1 to 3, a universal grounding wire operating rod includes an insulating rod 3 and an elastic hook 4, the bottom of the elastic hook 4 is provided with a first protrusion 44, and the bottom of the first protrusion 44 is provided with a second a groove. It also includes a rotary connector 1 and a rotary head 2 . the

The rotary connector 1 has a first connecting body 11 at the lower part and a second connecting body 12 at the upper part, the first connecting body 11 has a columnar body, and the top of the columnar body is provided with a square second protrusion, the The second connecting body 12 has a hollow cylindrical body with an opening on the top, a gap is set at the bottom of the hollow cylindrical body, and the two ends of the gap extend along the front-to-back direction. The second protrusion of the first connecting body 11 is connected to the The openings of the second connecting body 12 are connected by bolts to form a hinge connection, and the columnar part of the first connecting body 11 is connected to the top of the insulating rod 3 by bolts. the

The rotary head 2 has a third connecting body 21 located at the lower part and a fourth connecting body 22 located at the upper part, the third connecting body 21 is placed in the hollow of the hollow cylinder of the second connecting body, and is tightened by pressing the thumb bolt 13, the fourth connecting body 22 is placed in the first groove of the first protrusion, and fastened by horizontal bolts. the
