Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a ring for preventing snow from accumulating on electric wires in order to prevent snow from adhering to the electric wires.

PRIOR TECHNOLOGY The snow that adheres to electric wires can sometimes break the electric wires due to its load. Various efforts have been made to prevent this from happening. One way to do this is to form a ring out of plastic or the like and attach it to the electric wire. As shown in Fig. 1, the ring is made of plastic with a thin center, the extensions on both sides are curved inward, and the outer ends are The ring is provided with concave and convex connecting parts 5 and 6 for connection, and when attached to an electric wire, the ring formed as described above has a complicated shape and requires a special operating force in terms of connection and technology. In order to do this, after hooking one ring member to the electric wire so as to straddle it, use a specific scissor-type tool to manually pinch the ring member from both sides and bend it into a circular shape, and at the same time, remove the concave and convex connecting portions 5 at both ends. , 6 are combined to form a ring as shown in FIG. 6, and the ring is mounted on an electric wire as shown in FIG.

Problems that the invention aims to solve The conventional work of hooking each ring onto a wire and using a scissor-type tool to manually attach each ring is manual work, which causes great fatigue for the worker and is extremely time consuming. It is inefficient and has major disadvantages and inconveniences in installation. In order to solve this disadvantage, the present inventor invented an electric attachment instead of a scissor-type tool, but with the attachment according to this invention, it is difficult to suspend one ring on the wire. Therefore, the rings for difficult snow accumulation can be connected together and easily separated using an electric mounting tool.
The purpose is to make it possible to clip items without having to replenish them individually.

Means for Solving the Problem The required number of rings for difficult snow accumulation, which have a thin center, curve inward extensions on both sides, and have concave-convex connecting parts on both outer ends for connection, are It consists of a gutter-like welding table-type jig arranged in rows, and an ultrasonic welding machine in which contacts are arranged in rows to make contact at the straddle point at each connecting part of the rings for difficult snow accretion arranged in the jig. , a device for connecting rings for difficult snow accretion of electric wires, characterized in that each of the rings for difficult snow accretion are separably spot welded and integrated with each other by a contactor of an ultrasonic welding machine.

Function Each ring for difficult snow accretion is integrated with point welding so that each ring can be separated from the other by contacting the contact point of the ultrasonic welding machine at the straddle point, so it is easy to use with electric mounting equipment. It can be separated and attached without having to be supplied separately.

Arrange the required number of rings 1 for preventing snow accumulation on electric wires horizontally using a welding table-type jig 4 as shown in Fig. 3.
At the same time, use an ultrasonic welding machine 3 as shown in FIGS. 4 and 5 to connect the contacts 7.
The tips of the protrusions 8, which protrude like rods, are provided in such a way that each protrusion 8 can make straddle point contact with the connecting portion of each ring 1, 1, and the connecting portion of each ring 1, 1 Point welding is performed at point contact points 2, 2, . . . , and a large number of rings 1, 1, .

Effects As described above, this method uses the ultrasonic welding machine 3 to attach a large number of anti-snow rings, and the contacts 5 are straddled and brought into contact with the tips of the rings, so that they are welded all at once in an integrated manner. When installing the anti-snow ring on the wire using a mounting tool, the ring is automatically separated one by one by automatic feeding on the wire and can be installed securely, eliminating worker fatigue and making installation of the anti-snow ring extremely efficient. It is effective in preventing dangers during work.
