Description

Walking type foreign matter remover for overhead power transmission lines

technical field

The utility model relates to a tool for removing hanging objects of overhead electric power transmission lines, which is a walking type foreign matter remover for overhead electric power transmission lines.

Background technique

In recent years, hanging objects such as kite strings, plastic sheets, and canvases have posed serious hazards to overhead power transmission lines. They can easily cause single-phase grounding of transmission lines, short-circuits between phases, and other faults, resulting in the failure of normal operation of the line. For example, on the evening of February 25, 2009, citizens flying kites with metal wires in the Tiantan area of Beijing caused power equipment failures, causing power outages in some areas such as the Temple of Heaven.

At present, two methods of operation are mainly used for removing suspended objects of overhead power transmission lines: one is equal potential live operation processing; the other is after power failure, maintenance personnel go out to handle. The above two operating methods in the prior art require more manpower and material resources, and there are disadvantages such as complex operating procedures, long operating hours, heavy physical exertion of operators, and poor safety and reliability.

Contents of the invention

The purpose of this utility model is to provide a method that can remove foreign objects hanging on the overhead power transmission line without the need for equipotential on-line live work by operators using ground potential live work when the power transmission line is not powered off, and the structure is reasonable. The operation is simple, the use is safe, the operation efficiency is high, the effect of removing foreign matter is good, and the power of the workers is saved. The walking type foreign matter remover for overhead transmission lines.

The purpose of this utility model is achieved by the following technical solutions: a walking type foreign matter remover for overhead electric power transmission lines, which is characterized in that it includes a pulley frame, and a hanging wire pulley that rotates with a fixed axis is arranged on the upper part of the pulley frame. On the tackle frame, an inlet is provided under the side of the hanging pulley, a control panel is hinged on the top of the tackle frame, a knife rest is fixedly connected to the lower end of the tackle frame, and a foreign body removing knife is fixedly connected to the lower end of the knife rest.

The foreign body removal knife is an eagle knife.

The walking type foreign matter remover for electric power overhead transmission lines of the utility model has a hanging wire pulley with a fixed axis rotating on the upper part of the tackle frame, and an inlet is provided on the tackle frame below the side of the wire pulling pulley, and is fastened by a traction rope. The heavy object is thrown over the overhead transmission line above the operation point. The traction rope is wound on the top of the hanging pulley for manual traction, and the hanging pulley is hung on the overhead transmission line through the inlet provided under the side of the hanging pulley; The ground operator operates the traction rope to make the hanging pulley walk along the transmission line, and the foreign matter removal knife removes the hanging objects hanging on the transmission line; since the control panel is hinged on the top of the pulley frame, it can pass the angle between the control panel and the frame. Change to realize that the hanging wire pulley is hung on the overhead transmission line or taken off from the overhead transmission line.

The walking type foreign object remover for overhead power transmission lines of the utility model can realize hanging foreign objects on the overhead power transmission lines without the need for live work on the ground potential when the power transmission lines are not powered off. It has the advantages of reasonable structure, easy operation, safe use, high operating efficiency, good effect of removing foreign matter, and saving operators.

Detailed ways

Utilize accompanying drawing and embodiment to further illustrate the utility model below.

Referring to Fig. 1 and Fig. 2, the utility model walking type foreign matter remover for overhead power transmission lines has a pulley frame 1, and a rotating wire pulley 2 is placed on the fixed shaft 3 provided on the upper part of the pulley frame 1, and the pulley frame 1 is located below the side of the hanging pulley 2 and is provided with an inlet 8. A control panel 7 is hinged on the top of the tackle frame 1. A knife rest 6 is fixedly connected to the lower end of the tackle frame by bolts 4. The lower end of the knife rest 6 is fixed to There are foreign body removal knife 5. In order to make the walking-type foreign matter remover for overhead power transmission lines run smoothly on the overhead transmission lines, the structure of double fixed shafts 3 and double hanging pulleys 2 is adopted.

Referring to FIG. 3 , the foreign matter removing knife 5 of the present embodiment adopts an eagle-type knife.

When using the walking type foreign body remover for electric power overhead transmission lines of the present utility model: the operator uses a traction rope to fasten heavy objects and throws them over the overhead transmission line above the operation point, and the traction rope is wound on the top of the hanging pulley 2 The wire pulley 2 is hung on the overhead transmission line through the introduction port 8 provided under the side of the wire pulley 2 by manual traction; the ground operator operates the traction rope to make the wire pulley 2 walk along the transmission line, and there are 5 pairs of foreign matter removal knives The suspended objects hanging on the power transmission line shall be removed. Operate the control board 7 hinged on the top of the tackle frame 1, utilize the change of the angle of the control board 7 relative to the tackle frame 1, and realize that the line pulley 2 is hung on the overhead transmission line or taken off from the overhead transmission line.
