The utility model is described in detail below with reference to accompanying drawing.

Fig. 1 and Fig. 2 are respectively the front view and the side view of the ground wire hoisting rod of the embodiment of the present invention;

1 and 2, a grounding wire lifting rod 100 of this embodiment is used to lift the grounding wire, which includes an insulated rod body 1, a load-bearing hook 2, a buzzer electroscope 3 and a fixed pulley 5, wherein the rod body 1 It is an insulator and one end of it is fixedly connected with a load-bearing hook 2. The other end of the rod body 1 is provided with a fixed pulley 5. The buzzer electroscope 3 is set on the load-bearing hook 2 and is electrically connected with the load-bearing hook 2. It is lifted by using a grounding wire during work. The pole 100 effectively reduces the work burden of the staff on the pole and makes the grounding work easier. The insulated pole body 1 enables the staff on the pole to avoid physical contact with the ground soft copper wire.

At present, when performing grounding operations in the prior art, the personnel on the pole need to pull the grounding rod into the air after the electrical inspection operation is completed. The weight of the pulling includes the weight of the three grounding rods and the ground wire. After measurement, the The weight reaches 6kg, and it is very laborious to pull upwards on the rod. The utility model solves this problem by setting the fixed pulley 5 through the ground wire lifting rod 100 to change the pulling force mode.

After pulling the ground rod to the pole, when the staff is hanging the ground rod, one hand needs to support the weight of a ground rod and all the ground wires when hanging the first ground rod, and because the arm is stretched Yes, according to the principle of leverage, it can be seen that this process is very labor-intensive. The grounding wire lifting rod 100 of the utility model suspends the grounding rod in the air, so that the weight is borne by the ground personnel, thereby reducing the work of the operators on the rod.

In combination with the above, the two ends of the rod body 1 are respectively provided with annular connecting parts, and the load-bearing hook 2 and the fixed pulley 5 are respectively fixed on the two connecting parts. Here, the load-bearing hook 2 includes a main body part 7 and a hook part 8, wherein, The main body 7 is in the shape of a cuboid, and an arc-shaped groove is arranged on the side of the main body 7 facing away from the hook portion 8. Preferably, the arc-shaped groove is an arc-shaped groove, so as to be compatible with the buzzer electroscope. The surface radian of 3 is matched and fitted, which is more stable in structure; the buzzer electroscope 3 is embedded and fixed in the arc-shaped groove, and is electrically connected with the main body 7. When a sudden call occurs on the line, the buzzer The buzzer electroscope 3 will report to the police in time to prompt the staff on the pole to avoid accidents. (not shown in the figure) matching groove (not shown in the figure), and through the screw (not shown in the figure) and the washer (not shown in the figure) for fastening to the buzzer electroscope 3 for further fixation.

Referring to Fig. 1, the hook part 8 is formed by extending from one end of the main body part 7, and the width of the hook part 8 is the same as that of the main part 7. The total weight of the grounding wire to be hoisted, wherein the side of the main body 7 corresponding to the hook portion 8 is formed with a raised portion 6, and the raised portion 6 and the hooked portion 8 cooperate to prevent the grounding wire from lifting the boom 100 from the high-voltage wire Sliding down, although the grounding wire hoisting rod 100 may have a relatively large swing, the grounding wire hoisting rod 100 can be kept in a safe state due to the cooperation of the raised portion 6 and the hook portion 8 .

In addition, the other end of the main body 7 is formed with a cylinder (not shown in the figure), the side of the cylinder is provided with a hole, and a through hole matching the hole is provided along the radial direction of the connecting part, The cylinder is plugged into the connection part in the form of interference fit, and the pin 9 is pierced in the through hole and the hole to fix the cylinder and the connection part, so as to realize the connection of the cylinder. The body is fixedly connected with the rod body 1, which further improves the safety factor and avoids accidents in which the column body and the rod body 1 become loose.

In addition, preferably, the rod body 1 can also be composed of a rod main body 7 and a handle part 4 , wherein the rod main body 7 is detachably connected to one end of the handle part 4 , and the other end of the handle part 4 is fixedly connected to the fixed pulley 5 .

The material of the rod body 1 or the handle or the pulley in this embodiment is all insulating materials, wherein, preferably, the material of the pulley is plastic, so that the weight of the whole ground wire lifting boom 100 itself is very light, and the work of the staff on the rod is reduced to the greatest extent. load.

Although the grounding work is carried out after the electric test operation, it is necessary to always think that the line may be charged when working on the line, so the staff on the pole cannot touch the ground soft copper wire when performing the grounding operation. In the existing method, because the grounding process is too labor-intensive, the personnel on the pole easily ignore the safety issue. The grounding wire lifting boom 100 of the utility model solves the problem of body contacting the ground wire by reducing the work burden of the personnel on the pole.

Simultaneously, in order to avoid this type of problem, a buzzer electroscope 3 is specially set up on the ground wire lifting rod 100, and its purpose is to immediately warn the personnel on the rod when the line is electrified, and stop working, thereby avoiding major safety accidents.

To sum up, the grounding wire lifting boom 100 effectively solves various problems and potential dangers existing in current operations on the pole from many aspects.

The above embodiments are only exemplary embodiments of the utility model, and are not used to limit the utility model, and the protection scope of the utility model is defined by the claims.
