Description

[Detailed explanation of the invention] (Industrial application field) This invention makes it possible to separate many anti-snow rings to prevent the spread of snow that has fallen and frozen on electric wires installed between steel towers. This invention relates to a device for movably temporarily attaching an integrally connected ring connecting body to an electric wire.

(Prior Art) This type of ring A usually has a pair of semicircular ring parts B facing each other, as shown in FIGS. 2 and 3.
It has a structure in which one end is connected by a thin flexible connecting member C with a U-shaped cross section, and a mutually fitting member D is integrally formed at the other end of both ring portions B, and each ring A is spaced at a constant distance from the electric wire. It is installed and used. by the way,
Conventional ring attachment devices for attaching the above-mentioned rings A to electric wires are generally used by loading a plurality of independent rings A into a ring storage part, such as the device described in Japanese Patent Application Laid-Open No. 59-99907. Because of this structure, it takes time and effort to load the ring, and the number of rings that can be loaded is limited, so the ring must be loaded many times, which is very inconvenient. Therefore, in order to eliminate this drawback, recently, a ring connecting body A method has been developed in which one ring A at the rear end of the ring connecting body X is clamped and fixed to the electric wire Z while the ring X is intermittently moved along the electric wire Z by a predetermined distance.

(Problems to be Solved by the Invention) However, in order to implement the above-described ring attachment method, it was necessary to attach the ring connecting body to the electric wire in a movable manner.

This invention was developed in view of the above points, and aims to provide a temporary attachment device that allows the ring connecting body to be easily and reliably temporarily attached to electric wires with light operation, has a simple structure, and is convenient to carry. be.

(Means for solving the problem) The gist of this invention to achieve the above-mentioned purpose is to rotatably pivot one end of a pair of opposing angle irons of a predetermined length. , one end of the operating rod is fixed to the center position of each angle iron so as to intersect with each other, and a stopper member is provided on one operating rod so as to be able to come into contact with the other operating rod, and the above-mentioned The stopper member includes an adjuster whose contact position with the other operating rod can be adjusted.

(Function) According to the device of this invention, with a pair of angle irons open, the ring connecting body is inserted into the angle iron with the opening facing upward, and the ring connecting body is inserted into the electric wire together with the angle iron through those openings. The ring connecting body is temporarily attached to the electric wire at once by loosely inserting it from the bottom and closing both angle irons via both operating rods. The closing angle of the angle iron can be adjusted according to the ring diameter and the wire thickness.

(Example) Hereinafter, an example of the temporary attachment device for a ring connecting body of this invention will be described based on the drawings.

FIG. 1 is an overall perspective view of the device, and FIG. 2 is a cross-sectional view showing a temporary installation mode of the ring connector.

In the drawings, 1 represents a pair of predetermined lengths (e.g.
The angle irons are long enough to insert a connecting body consisting of about 40 rings, and each angle iron 1 is made to face each other, and one end of the angle iron 1 is pivoted via a support shaft 2 so that the other end can be opened. do. 3 is a pair of operating rods, each of the angle irons 1
One end of each operating rod 3 is fixed to the central position of the angle iron 1 so as to intersect with each other, and the other end of the angle iron 1 can be opened and closed by operating each operating rod 3. .

Reference numeral 4 denotes a stopper member that restricts the rotation range of the operating rod 3, and is provided with an adjustment screw 5 as an adjuster star that is rotatably screwed together. The screw 5 is fixed so that its tip abuts vertically on the upper edge of the other operating rod 3.

Next, the manner of use of the apparatus of the embodiment having the above configuration will be explained. As shown in FIG. 2, with the pair of angle irons 1 open, insert the ring connecting body X into the angle iron 1 with the opening facing upward, and attach the ring connecting body X to the electric wire Z. 1 and through their openings so as to surround the electric wire Z, and bring both operating rods 3 close together until the adjustment screws 5 of the stopper member 4 come into contact with each other, until the openings of both angle irons 1 are approximately By closing, the ring connecting body X is entirely reduced in diameter around the flexible connecting member C, and is movably temporarily attached to the electric wire Z at once. Note that by rotating the adjustment screw 5 of the stopper member 4 and adjusting the contact position with the other operating rod 3, the closing angle of the angle iron 1 can be adjusted. It is also possible to adjust the temporary attachment state of the ring connector X to the electric wire Z according to the thickness of the wire Z. Also,
The stopper member 4 of the above embodiment has an adjustment screw 5.
Although the adjustment screw 5 is provided, the adjustment screw 5 may be omitted if the structure is to be further simplified.

(Effects) As explained above, since the ring connecting body temporary mounting device of this invention has the above-described configuration, it has the following effects.

(1) A pair of angle irons are used as the members that contact the ring connector and apply force in the direction of reducing its diameter, so even if the diameter of the ring connector is different, the four When the angle iron comes into contact with the spot, a clamping force is effectively applied to the ring connecting body, and in combination with the operating rod, the ring connecting body can be reliably temporarily attached to the wire with extremely light force, and it can be used to connect a wide range of rings with different diameters. Can be applied to the body.

(2) Since angle iron is used as described above, commercially available products can be used and manufacturing is easy, so the product can be provided at low cost.

(3) The structure is simple and relatively lightweight, making it convenient to carry and highly durable.
