Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a climbing prevention tool for vine plants, etc., which prevents vine plants, etc., from winding around and climbing around a branch line supporting a utility pole.

[Prior art] When utility poles are erected in mountains, fields, levees, vacant lots, etc., vines such as vines and kudzu wind up on the branch lines that support the utility poles, and reach up to the electric wires installed between the utility poles. However, this may cause an accident such as a leak. Conventionally, for example, Japanese Utility Model Publication No. Sho 61-20202 discloses a method for preventing the vines from rolling up. "A tool for preventing climbing of vines and small animals on utility pole branches" is known.

This preventive tool is composed of a conical cylindrical body formed by superposing a pair of half-divided bodies on each other, a long rod installed inside the conical cylindrical body, and a narrowing member provided on the long rod. It This preventive tool first applies one half of the half body to the utility pole branch line with its large diameter facing the ground, tightens the utility pole branch line with the long rod and the clasping member, and then bolts the other half. The body is piled up and tightened with bolts to assemble and fix the position.

[Problems to be solved by the invention] Since a preventive tool for preventing climbing of vine plants and the like is required to be installed at a high position of the utility pole branch line, bolting work of the preventive tool is performed at a high place. Furthermore, since it is often installed on a utility pole branch line installed on a steep slope such as in a mountainous area, the installation work is performed on a place where the scaffold is unstable. Therefore, it takes a very long time to attach and fix the position of the above-mentioned preventive tool, which is often bolted.

The present invention has been made for the purpose of providing a climbing prevention tool for a vine plant or the like to a utility pole branch line that can be easily fixed at a desired position.

[Means for Solving the Problem] The gist of the present invention is to provide a funnel body having a wide mouth and a small-diameter guide port for supporting a utility pole branch line, and the wide mouth of the funnel body is directed toward the ground. In a device for preventing climbing of vines and the like on a utility pole installed on a branch line, a support member installed inside the funnel body and having a guide ring for passing the utility pole branch line in the center, and a member facing each other around the utility pole branch line A pair of leaf spring members that hold the electric pole branch line by urging it in the radial direction, and a semicircular notch that comes into contact with the outer periphery of the electric pole branch line is provided at the tip, and the tip is of the funnel body. A tool for preventing climbing of a vine plant or the like on a utility pole branch line, comprising: a part disposed on a part of the support member so as to face the wide mouth direction;

[Operation] Since the tool for preventing climbing plants such as vines on the utility pole branch is equipped with a support member that is installed inside the funnel body and has a guide ring in the center, the utility pole branch line is passed through the axial center of the funnel body. be able to.

Each leaf spring member is arranged on the support member so as to hold the utility pole branch line, and the tip of each leaf spring member faces the wide mouth direction of the funnel body and abuts the utility pole branch line at the notch portion,
The spring force biases the utility pole branch line in the radial direction. Due to the frictional force between the leaf spring member and the utility pole branch line due to this urging force, the preventive tool can be prevented from sliding down in the direction of the ground and can stay at a certain position. However, if the above-mentioned preventive tool is pushed up, the pushing-up force acts in the direction of weakening the above-mentioned biasing force, so that the above-mentioned preventive tool can be moved upward. For this reason, it is possible to fix the climbing prevention tool such as a vine plant to the power pole branch line only by moving it upward to a desired position after mounting it below the power pole branch line.

[Embodiment] An embodiment of the present invention will be described with reference to the drawings. A climbing prevention tool (hereinafter simply referred to as a prevention tool) 1 for climbing plants such as vines on a utility pole branch is shown in a partially cutaway front view of FIG. 1, a bottom view of FIG. 2, and a left side view of FIG. As shown in the figure, the funnel body 3, a support member 5 that is installed inside the funnel body 3 and allows a utility pole branch line (hereinafter, simply referred to as a branch line) L to pass through the shaft center of the funnel body 3, and a tip end of the funnel body 3. It is composed of a pair of leaf spring members 7a, 7b which are fixed to a part of the support member 5 facing the wide mouth 3a and urge the branch line L in the axial direction.

The funnel body 3 has a pair of hoods 10a, 10b formed by cutting a pyramidal cylinder in the axial direction and dividing the hood into two flanges 11a, 11b.
It is formed by joining parts with bolts and nuts. The funnel body 3 formed in this manner is formed with a wide mouth portion 3a having a diameter such that vine plants are hard to wind, a guide opening 3b for guiding the branch line L to the inside, and a cylindrical body 3c. The hoods 10a and 10b are made of a lightweight material such as synthetic resin having weather resistance.

As shown in FIG. 4, the support member 5 is a plate-shaped support member main body 20 having a semi-cylindrical guide 20a through which a branch line L is inserted in the center.
And a guide member 21. The guide member 21 includes a pair of nuts 22 welded to both sides of the guide 20a of the support member body 20.
A guide ring 23 for passing the branch line L is formed in the center of the support member 5 by being screwed to a and 22b. The support member 5 is a cylindrical body 3c.
An inner edge of the wide mouth portion 3a side is erected on a recessed portion 11c of a flange 11a provided on one of the hoods 10a and screwed.

As shown in FIG. 5, the leaf spring members 7a and 7b are leaf spring members punched out in a substantially L-shape, and the wide portions thereof are bent at right angles to form attachment portions 30a and 30b. Leaf spring body 31
A and 31b are bent at a predetermined angle in the middle. Further, semi-circular cutouts 33a, 33b that come into contact with the outer circumference of the branch line L are provided at the tips 32a, 32b of the leaf spring body portions 31a, 31b. The two leaf spring members 7a and 7b are symmetrical, and FIG. 5 shows the leaf spring 7a attached to the left side of the support member 5 shown in FIG.

The leaf spring members 7a and 7b having the above-described shapes are screwed to the support member 5 with the spacers 34a and 34b sandwiched between the mounting portions 30a and 30b. At this time, both ends 32a, 32b of the leaf spring members 7a, 7b are
As shown in FIG. 6, the funnel body 3 faces each other.
Facing toward the wide mouth portion 3a, and the space between the two tips 32a, 32b is smaller than the outer diameter of the branch line L. In addition, the spacers 34a, 34

Next, a method of attaching the preventive tool 1 to the branch line L will be described.

First, the hollow portion 11c of the flange 11a of the one hood 10a.
The support member main body 20 is hung on and fixed with screws. Next, the hood 10a is applied to the branch line L so that the hem portion faces the ground, and the leaf spring members 7a and 7b are biased outward,
As shown in FIG. 6, notches 33a, 33b of the leaf spring members 7a, 7b
Is brought into contact with the outer circumference of the branch line L. When the urging of the leaf spring members 7a, 7b is stopped, the branch line L is held by the tips 32a, 32b of the leaf spring members 7a, 7b.

Then, when the guide member 21 is screwed to the support member main body 20, the branch line L penetrates the guide ring 23. Then the other hood
10b are overlapped and hoods 10a and 10b are flanged to each other 11a and 11b
Then, the funnel body 3 is formed by integrally joining with the bolts and nuts. At this time, the rubber non-slip member 40 shown in FIG. 7 is fixed to the inner wall of the guide port 3b with an adhesive with the tip of the protruding piece 41 facing the ground. This completes the attachment of the preventive tool 1.

In the preventive tool 1 attached as described above, each leaf spring member 7a, 7b biases the branch line L in its axial direction by its biasing force. Since the urging force of the leaf spring members 7a, 7b is sufficiently strong, the frictional force between the leaf spring members 7a, 7b and the branch line L prevents the preventive tool 1 from slipping down in the direction of the ground and stays at a fixed position. You can stay. In addition, non-slip member
Since 40 is open, the preventive tool 1 is firmly fixed in a fixed position. However, when the preventive tool 1 is pushed up, the pushing force works in the direction of weakening the biasing force of the leaf spring members 7a, 7b, so that the preventive tool 1 can be moved upward by pushing it up with a certain force or more. . Therefore, if the preventive tool 1 is pushed up by a bamboo pole or the like and moved to a predetermined position, the preventive tool 1 is fixed at the predetermined position.

Since the utility pole branch line L is usually a combination of three or more metal element wires such as galvanized steel wire, the leaf spring member 7
If a spring steel material is used for a and 7b, it will bite into the surface of the metal element wire, and the prevention tool 1 will be prevented from slipping down.

As described above, in the preventive tool 1 of the present embodiment,
Since the bolting work for assembling the preventive tool 1 can be performed on the ground and then pushed up with a bamboo rod or the like to move it to a desired position and fix the position, the work of bolting the preventive tool 1 to the branch line L is not necessary. In addition, since work at high places is completely eliminated, workability is remarkably improved. In addition, the safety of workers is ensured.

In the above embodiment, the funnel body 3 is connected to the pair of hoods 10a and 10b.
However, the funnel body may be integrally molded, a separating portion extending in the axial direction may be provided, and flanges may be provided on both sides of the separating portion, and the utility pole branch line may be passed through the separating portion and the flange may be bolted. .

Further, in the above-described embodiment, the support member 5 includes the plate-shaped support member main body 20 having the semi-cylindrical guide 20a, and the guide member 21.
However, the supporting member may be a disk 50 provided with a guide port 50a for guiding the branch line L to the center thereof, as shown in FIG. 8 (A). In this case, the leaf spring members 51a, 51b having a shape capable of being attached to the flat surface of the disk 50 by omitting the attaching portions 30a, 30b of the leaf spring members 7a, 7b of the above embodiment are used. Further, instead of the disc 50, a pair of semi-discs 60 shown in FIG. 8 (B), each having a small semi-circle 60a through which the branch line L passes, may be provided, and each of the semi-discs 60 may be attached to the hoods 10a and 10b. Good.
If you use this disc 50 or a pair of semi-discs 60,
