Description
Technical Field
The utility model relates to a lead ground wire, electric power optical cable antivibration gold utensil, especially relate to an antivibration hammer fastener with bump belongs to and leads ground wire, electric power optical cable annex technical field.
Background
The span between towers in a high-voltage transmission line is large, the towers are also high, and when cables such as a ground wire, an optical fiber composite overhead ground wire (OPGW), an all-dielectric self-supporting optical cable (ADSS) and the like erected on the towers are blown by breeze, vibration can occur, and particularly, the vibration can be severe in case of strong wind. The cable is damaged due to fatigue caused by long-time and periodic vibration, and strand breakage and wire breakage of the cable can be caused in serious conditions, and even hardware fittings and insulators can be damaged.
In order to prevent and reduce the vibration of the cable, several dampers are usually installed on the cable near the tower. When the line vibrates, the damper moves up and down to generate an acting force which is asynchronous or even opposite to the line vibration, so that the amplitude of the cable can be reduced, the vibration frequency can be changed, and the obvious vibration of the cable can be eliminated. The damper is mainly fixed with the cable through different wire clamps. The clamp part of the common preformed armor rod type damper is in a hammerhead type with a convex nail, the clamp main body and the armor rod are in a point contact mode, the contact area is small, and the armor rod is easy to slip, so that the damper falls off, the due anti-vibration function is lost, and potential safety hazards are brought to a high-voltage transmission line.
Therefore, how to improve the structure of the damper wire clamp, the grip force between the damper wire clamp and the cable is enhanced, the damper is ensured not to fall off, the safe operation of the high-voltage transmission line is ensured, and the problem to be solved by the industry is solved.
Disclosure of Invention
An object of the utility model is to overcome exist not enough among the prior art, provide an anti-vibration hammer fastener with bump, through add multirow salient point at the middle part of the fastener, form the passageway of placing the hank reel between the salient point, increase the area of contact of hank reel and fastener, improve the power of holding of hank reel and fastener, ensure that the anti-vibration hammer does not drop.
According to the technical scheme provided by the utility model, a damper fastener with bump, including fastener main part and hank silk, the fastener main part is including the arc portion, smooth portion and the bottom that connect gradually, the middle part of arc portion is equipped with the draw-in groove, and the upper and lower both ends of arc portion form the crotch form, the inside wire casing that is equipped with of arc portion of fastener main part the wire casing is equipped with a plurality of rows of salient points, the hank silk is laminated inside the fastener main part in the passageway between salient point and being located.
As a further improvement, the wire groove is a spiral groove.
As a further improvement of the utility model, every row of protruding points is arranged along the direction that the wire casing extends.
As a further improvement of the utility model, the bottom is provided with a pin shaft hole.
As a further improvement, the salient points are provided with 1 to 4 rows, and the quantity of each row is 2 to 6.
The utility model has the advantages that:
through increasing multirow salient point in the fastener main part, the hank silk is laminated in the passageway between the salient point and is located inside the fastener, has increased the area of contact of hank silk with the fastener main part, has further improved the grip of fastener and cable, reaches the difficult mesh that drops of damper.

Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings.
As shown in the figure, an anti-vibration hammer fastener with bump, including fastener main part and hank silk, the fastener main part is including arc portion 1, smooth portion 2 and the bottom 3 that connects gradually, the middle part of arc portion 1 is equipped with draw-in groove 4, and the upper and lower both ends of arc portion 1 form the crotch form, 1 inside wire casing 6 that is equipped with of arc portion of fastener main part be equipped with a plurality of rows of salient points 7 in the wire casing 6, the hank silk is laminated in the passageway between the salient points and is located inside the fastener main part.
The wire groove 6 is a spiral groove.
The raised points 7 of each row are arranged along the direction in which the trunking extends.
The bottom 3 is provided with a pin shaft hole 5 for connecting the damper.
The protruding point 7 is provided with 2 rows, and every row's quantity is 3 to 2 rows of protruding points 7 are taken as an example, and protruding point 7 and two lateral walls of wire casing 6 form 3 clearances, can hold 3 hank silks and pass, and the hank silk is arranged in the fastener completely for the fastener is difficult for droing.
The principle of the utility model lies in:
the utility model provides a pair of novel damper fastener through the inside multirow salient point that sets up of fastener main part, not only sets up the hank wire inside the fastener, has also increased the area of contact of hank wire and fastener main part simultaneously, has further improved the grip of fastener and cable, reaches the difficult purpose that drops of damper, extensively is applicable to high-tension transmission and fiber communication lines such as ground wire, OPGW, ADSS.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be considered as the protection scope of the present invention.
