Description

Pre-twisted winding aid

technical field

The utility model relates to an auxiliary tool for electricians in a power system, in particular to a pre-twisted wire winding auxiliary device used for repairing wires of transmission lines.

Background technique

At present, for 35KV and above transmission lines operating in the power system, when a small amount of broken strands occurs in the wire, the usual treatment method is to use the same type of aluminum alloy pre-twisted wire as the wire to wind and repair the wire surface. At present, our company does not have professional tools for winding pre-twisted wires when repairing transmission line wires. The traditional operation method is to press one end of each pre-twisted wire on the wire with the left hand, and wind the wire along the direction of the wire with the right hand, or Use non-professional tools such as screwdrivers for auxiliary winding. Due to the large number of pre-twisted wires and high rigidity of the above traditional operation methods, when the number of wires reaches a certain number, there will be unsightly appearance and uneven ends, which will induce electrical discharge at the tip of the conductor, wire breakage and other safety hazards. At the same time, it is time-consuming and labor-intensive in the operation process, the work efficiency is not high, the labor intensity is high, and the time-consuming is long.

Utility model content

The technical problem to be solved by the utility model is to provide a pre-twisted wire winding auxiliary device, which solves the technical problem of lack of fast and safe professional tools for winding pre-twisted wires when repairing transmission line wires, and compared with traditional manual work , has the characteristics of novel and simple structure, convenient use, flexibility, safety, saving time and labor, and improving work efficiency.

The technical solution adopted by the utility model is: a pre-twisted wire winding auxiliary device, including a U-shaped frame, one side of which is provided with an elbow, one side of the elbow is provided with a first fixing hole, and the other side is provided with a There is a second fixing hole, the first fixing hole and the second fixing hole are located on the same vertical central axis; a fixing rod is also provided, and the fixing rod is used in conjunction with the first fixing hole and the second fixing hole.

The frame body on one side of the U-shaped frame and the frame body on the other side have a symmetrical structure along the horizontal central axis of the U-shaped frame.

One side of the U-shaped frame is also separately provided with a threading rod.

Optimally, the tail end of the elbow is flat and forms an angle of 30° with the horizontal plane.

Optimally, a handle is provided at one end of the fixing rod.

Optimally, the fixing rod is a threaded rod, which is threadedly engaged with the first fixing hole and the second fixing hole when in use.

Optimally, the tail end of the threading rod is flat.

The beneficial effects produced by adopting the above technical scheme are: the utility model fixes the wires in the elbows on both sides of the U-shaped frame through the fixing rods and fixing holes on both sides of the U-shaped frame, and does not need to press the wires by hand, which can greatly reduce the operating cost. Labor intensity; then wind one end of the pre-twisted wire on the threading rod, and turn the U-shaped frame to quickly and safely wind the pre-twisted wire to the wire, saving time, labor and effort, and improving work efficiency.

The utility model has the advantages of simple structure, convenient use and extensive popularization value, and is especially suitable for repairing wires of high-voltage transmission lines above 35KV.

Detailed ways

Referring to accompanying drawing 1 and accompanying drawing 2, a kind of pre-twisted wire winding auxiliary device comprises U-shaped frame 1, can adopt 10mm*800mm prestressed steel bar. Its side frame body is provided with elbow 2, and the arc diameter of elbow 2 should be greater than the wire diameter. In order to better contact with the wire, especially the ground wire, press the tail end of the elbow 2 into a flat shape and form an angle of 30° with the horizontal plane. One side of the elbow 2 is provided with a first fixing hole 3, and the other side is provided with a second fixing hole 4, and the first fixing hole 3 and the second fixing hole 4 are located on the same vertical central axis and serve as fixing wires. Also be provided with fixed rod 5, described fixed rod 5 is threaded rod, and its one end is provided with handle 7, is convenient to operate. The fixing rod 5 is threadedly used with the first fixing hole 3 and the second fixing hole 4 .

The frame body on one side of the U-shaped frame 1 is symmetrical to the frame body on the other side along the horizontal central axis of the U-shaped frame 1 .

One side of the U-shaped frame 1 is also separately provided with a threading rod 6. In order to facilitate the operation of the pre-twisted wire 9, its tail end is pressed into a flat shape, and the tail end exposes the arc position of the elbow 2 by about 500mm.

During use, lead wire 8 is passed through the elbows on both sides of the U-shaped frame earlier, and the fixed rods 5 on both sides of the U-shaped frame are respectively threaded with the first fixed hole 3 and the second fixed hole 4 on both sides of the U-shaped frame, so that the The wire 8 is fixed in the elbows on both sides of the U-shaped frame, and then one end of the pre-twisted wire 9 is wound on the threading rod 6, and the other end is placed on the surface of the wire 8, holding the U-shaped frame 1 in hand, and clockwise along the wire 8 Rotate, because the pre-twisted wire itself is in a spiral shape, the pre-twisted wire 9 can be quickly and safely wound on the wire 8 under the drive of the pre-twisted wire winding auxiliary device. the
