Description

TJ type jumper spacer for easy adjustment

technical field

The utility model relates to an easily adjustable TJ-type wire jumper spacer, which is used for the support and protection of multi-split jumper wires and wires in tension towers of power transmission lines.

Background technique

In transmission lines, jumpers often touch shielding rings and wires. Once jumpers touch wires or shielding rings, under the action of external forces such as wind, it is easy to cause wear and electrochemical corrosion of jumpers and wires. damage to the equipment.

In order to eliminate the above-mentioned defects, the construction workers need to readjust the TJ jumper spacer. The existing TJ jumper spacer includes a connecting rod and two chucks respectively fixed on the two ends of the connecting rod. When readjusting, it is necessary to first Open the clamps at both ends of the TJ-type jumper spacer, remove the spacer, and then re-select the verification position to ensure that the jumper, shielding ring, and wire are verified, and then install the spacer. During installation, personnel are required to cooperate with fixing the jumper and From the relative positions of the wires, it can be seen that the above-mentioned defect elimination process is cumbersome and requires the cooperation of multiple people.

Utility model content

The technical problem to be solved by the utility model is to provide a TJ-type wire jumper spacer that is simple in structure, easy to maintain, and can quickly eliminate hidden dangers of touching.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical scheme: the TJ type wire jumper spacer that is easy to adjust includes a connecting pipe, a first wire clip and a second wire clip, and the inner surface of the connecting pipe is provided with an internal thread, so The first threaded rod is provided with a first threaded rod, the second threaded rod is provided with a second threaded rod, the first threaded rod is threadedly connected to one end of the connecting pipe, and the first threaded rod is A first nut is threaded, the second threaded rod is threaded at the other end of the connecting pipe, and a second nut is threaded on the second threaded rod.

Further, the opposite sides of the middle part of the connecting pipe are respectively provided with construction holes penetrating through the pipe wall of the connecting pipe.

Further, the connecting pipe, the first wire clip and the second wire clip form a "one"-shaped structure.

Further, the first wire clamp and the second wire clamp have the same structure, and both are composed of a base, a handle, a screw and a set nut, one end of the handle is hinged to one end of the base, and one end of the screw The other end of the base is moved through and hinged to the other end of the grip body, the set nut is screwed to the other end of the screw rod, grooves are respectively provided on the opposite surfaces of the base and the grip body.

Further, the first threaded rod and the second threaded rod are respectively fixed on the bases of the first wire clip and the second wire clip.

The beneficial effects of the utility model are:

The utility model has a simple structure and is easy to manufacture. After the first wire clamp and the second wire clamp are respectively fixed on jumpers, wires or tension rods, the first threaded rod and the second threaded rod can be adjusted by twisting the connecting pipe. The protruding length, thereby changing the distance between the first clamp and the second clamp, increasing or reducing the distance between the jumper wire and the wire (tension rod), and through the first nut and the second nut to connect the first thread The rod and the second threaded rod are fastened to the connecting pipe. Therefore, in the completion acceptance and daily operation and maintenance work, when the jumper wire is found to be in contact with the wire or the shielding ring, the utility model does not need to remove the spacer bar entirely, and the two wire clips can be adjusted only by adjusting the connecting pipe Therefore, the hidden danger of the jumper touching the wire or the shielding ring can be eliminated very quickly, and this design can also facilitate installation and debugging during installation.

When the wire clip is damaged, the utility model can directly replace the corresponding wire clip without replacing the entire wire jumper spacer, and has the advantages of easy maintenance and low cost.

detailed description

Below in conjunction with accompanying drawing, the utility model will be further described:

See Figure 1.

The TJ-type wire jumper spacer that is easy to adjust according to an embodiment of the utility model includes a connecting pipe 1, a first wire clamp 21 and a second wire clamp 22, the inner surface of the connecting pipe 1 is formed with internal threads, and the first The clamp 21 is provided with a first threaded rod 31, the second clamp 22 is provided with a second threaded rod 32, the first threaded rod 31 is threadedly connected to one end of the connecting pipe 1, and the first A first nut 41 is threaded on the threaded rod 31 , the second threaded rod 32 is threaded on the other end of the connecting pipe 1 , and a second nut 42 is threaded on the second threaded rod 32 .

Compared with the prior art, the utility model connects the first wire clamp 21 and the second wire clamp 22 by setting the first threaded rod 31 and the second threaded rod 32 to thread the connecting pipe 1, and the first wire clamp 21 and the second clamp 22 are used to fix on jumpers, wires or tension rods, by twisting the connecting pipe 1, the extension length of the first threaded rod 31 and the second threaded rod 32 can be adjusted, so that the jumper The distance from the wire (tension rod) increases or decreases, and the first threaded rod 31 and the second threaded rod 32 can be fastened to the connecting pipe 1 by the first nut 41 and the second nut 42 .
