Description

Transmission line multifunctional foreign object processor

technical field

The invention belongs to the technical field of electric power maintenance tools, and in particular relates to a multifunctional foreign object processor for power transmission lines.

Background technique

During the operation of power transmission and transformation equipment, foreign objects are often entangled on high-voltage lines, which can easily cause ground faults on 10kV overhead lines. The processing tools of the prior art can generally only handle foreign objects that are not tightly wound on the electric wires, such as plastic films, etc., but cannot handle thinner ropes wound on the electric wires, such as kite strings. And the tool of prior art generally adopts the insulating operating rod, and its head end is fixed with hook, and the angle of hook is fixed and can not be adjusted, thus greatly increases difficulty of operation when dealing with foreign objects, increases working time, affects work efficiency, and exists Security risks.

The Chinese patent with application number 201120028708.X discloses an overhead high-voltage transmission line foreign object processor, which belongs to an overhead transmission line maintenance tool, and is characterized in that the overhead high-voltage transmission line foreign object processor mainly consists of a ratchet, an upper rotating hook, and a lower rotating shaft. , upper and lower scissor blades and an operating rod. The upper rotating hook is a long cylinder with a long rod right-angle hook on the top, and the lower rotating shaft is a long cylinder with external threads or internal threads on the lower end. A ratchet is installed between the lower end of the hook and the upper end of the lower rotating shaft to connect with each other. On the right periphery of the lower end of the upper rotating hook and on the right periphery of the upper end of the lower rotating shaft, the knife-edge is zigzag and has a hook respectively. The upper and lower scissor blades are elongated. The upper and lower scissor blades are stacked up and down and the sawtooth-shaped blades are correspondingly reversed. A slender operating rod is screwed on the lower end of the lower rotating shaft to effectively handle overhead high-voltage power transmission. Foreign matter on the line ensures the reliability of power consumption. The processor of this utility model can process thin wires such as kite wires, but if it is cut continuously during operation, it is necessary to remove the hook head of the upper rotating hook from the overhead power line, and tear it hard until the foreign matter is shredded and cleaned up. In the process of tearing, it is easy to damage the overhead transmission line, which has certain potential safety hazards and also poses a certain threat to the safety of staff.

Contents of the invention

The technical problem to be solved by the present invention is to provide a multifunctional foreign object processor for transmission lines, which can handle not only foreign objects that are not tightly wound on the electric wire, such as plastic films, but also thinner ropes that are wound on the electric wire, such as Kite wire, etc., can also adjust the different angles of the cutter head, making it more convenient and easy to deal with foreign objects, not easy to damage the transmission line, and can measure the distance between the worker and the foreign object or the transmission line to keep the worker away from the power transmission lines to ensure their personal safety.

In order to solve the above-mentioned technical problems, the present invention adopts the following technical scheme: the multi-functional foreign object processor for transmission lines includes an insulating operating rod, and the front end of the insulating operating rod is connected with an operating cutter head, and the insulating operating rod and the operating cutter head are passed through Tooth joint connection. The head end of the operating rod in the prior art is basically in the shape of a single hook or a blade for cutting, which cuts and drops the foreign matter and separates it from the power transmission line. Cutting, sawing, hooking, etc., and connected by toothed joints, the operating cutter head can be adjusted at different angles, which is convenient for the staff to deal with foreign objects at different positions and angles. It is more convenient and easy, and it is not easy to damage the transmission line.

After the foreign matter is removed, the straight rod is relatively long, so it is not easy to retract, and at this time, the foreign matter at the head end is easy to scatter, and the operation is difficult. The present invention uses a telescopic rod to replace it. The straight rod can conveniently collect the foreign matter at the head end of the operating rod. Just unscrew the telescopic node, retract the upper section of rod back, then unscrew the next telescopic node, and then retract the upper section of rod, so that the foreign objects at the head end can be easily retrieved. When operating in this way, the foreign matter at the head end can be collected back smoothly and slowly, and it is not easy to scatter, which greatly reduces the difficulty of operation.

Preferably, at least two telescopic nodes are arranged on the telescopic rod. When the insulating operating rod is extended, first tighten the telescopic node near the head end, then stretch out the rod section slightly away from the head end, and then tighten the telescopic node on this section, and so on, until the last telescopic node near the end of the telescopic rod is tightened, The telescoping rod is extended to the maximum. When the insulating operating rod is retracted, the order is reversed. First, loosen the telescopic node near the end, retract the rod segment, and then operate the telescopic nodes in the direction of the head end in sequence until the rod segment at the head end is retracted, and the telescopic rod retracts. to the shortest.

The invention discloses a multifunctional foreign object processor for transmission lines, which can not only handle foreign objects that are not tightly wound on electric wires, such as plastic films, but also handle relatively thin ropes wound on electric wires, such as kite strings, etc. The different angles of the cutter head can be adjusted to make it more convenient and easy to deal with foreign objects, and it is not easy to damage the transmission line. It can also measure the distance between the staff and the processed foreign objects or the transmission line, keep the staff away from the transmission line, and ensure their personal safety.
