Description

Transmission line foreign body removal tool

technical field

The utility model relates to the technical field of high-voltage transmission line maintenance, in particular to a tool for removing foreign matter from a transmission line.

Background technique

In recent years, there have been more and more power transmission lines in the urban and suburban junctions. The surrounding areas of the lines are faced with various factors such as residents flying kites, using greenhouses or plastic film to grow vegetables, hanging banners at weddings and funerals, installing arches, and releasing balloons, etc., resulting in foreign objects. The risk of falling on the conductors, ground wires and towers of transmission lines increases year by year, threatening the safe operation of transmission lines. Among them, conductors, ground wires hanging points, and anti-vibration hammer parts are the most easily entangled parts, and are not easy to fall off and remove.

However, as shown in Figure 2, the foreign body removal tools commonly used in the field of power transmission include operating rod a and operating rod head b, of which the operating rod a is mostly modified, using an old-fashioned equal-diameter reaming rod, with a price of 110 thousand Take the volt specification as an example, a section of 1.5 meters, which needs to be assembled on the ground during operation. The grounding knife switch is not specially designed for picking up foreign objects. During use, the foreign objects cannot be picked up smoothly, and the overall operation is difficult.

Utility model content

The purpose of the utility model is to provide a power transmission line foreign object removal tool that can easily and quickly remove foreign objects wrapped around conductors and ground wires for different types of suspended foreign objects and overlapping positions.

The tool for removing foreign objects in power transmission lines provided by the utility model includes a rod head and an insulating telescopic operating rod. The rod head is installed on the insulating telescopic operating rod through a universal coupling. An upward arrow is arranged, a curved hook is arranged on one side of the rod head, and a saw blade with the tip of the tooth facing downward is arranged on the other side of the rod head.

In order to make the crotch hook of the present utility model capable of pulling off foreign objects, knife teeth are provided on the inner side of the crotch hook.

In order to save labor when using the saw blade of the utility model, the tooth surface of the saw blade is bent at the lower end of the rod head.

Compared with the prior art, the utility model has the following advantages:

1. By adopting an insulated telescopic operating rod, it can not only meet the requirements of insulation performance and safety distance of the corresponding voltage level, but also can be retracted and carried with one hand when going up and down the tower, which reduces the labor intensity of operators.

2. Through the arrow on the upper end of the rod head, the tightly wound foreign matter can be easily poked; through the hook on one side, the foreign matter can be easily loosened; through the saw blade on the other side, the foreign matter can be easily cut off, so as to meet the requirements of the utility model. A new type of operation for various materials and winding methods.

3. The universal coupling is used for connection, which can facilitate the multi-angle and multi-directional rotation positioning of the rod head of the present invention on the operating rod, and has stronger applicability.

The utility model is safe, practical, light and handy, easy to process, install and carry, and can realize the light and fast removal of foreign matter in the power transmission line.

Detailed ways

As can be seen from Fig. 1, the foreign body removal tool for transmission lines of the present utility model includes a rod head 1 and an insulated telescopic operating rod 2, wherein an upward arrow 11 is arranged on the upper end of the rod head 1, and an upward arrow 11 is arranged on the rod head. 1 is provided with a hook 12 on one side, and on the other side of the rod head 1 is provided with a saw blade 13 with the tip facing down. The rod head 1 is installed on the insulated telescopic operating rod 2 through a universal coupling 3 .

It can also be seen from FIG. 1 that a knife tooth 121 is provided on the inner side of the crotch 12 of the present invention, and the tooth surface of the saw blade 13 is bent at the lower end of the rod head 1 .

In the utility model, the insulated telescopic operating rod 2 can be made by reforming the operating rod of an electroscope pen, which reduces the production cost of the utility model.
