Description

[Detailed description of the invention] The present invention relates to a cover that encases the connection between a utility pole's guy wire (a wire that is stretched diagonally from the top of the utility pole to the ground so that the pole can withstand the tension and wind pressure of overhead distribution lines) and an anchor bolt planted on the ground.

This type of cover has been available for some time, but since it was used to connect one branch line of a utility pole to an anchor bolt on the ground, a simple cylindrical cover was sufficient. However, in recent years, overhead distribution lines have tended to have larger diameters due to demands such as increasing power transmission capacity, reducing transmission losses, and improving voltage fluctuation rates.
As a single branch line is no longer enough, power poles are now being stretched using two branch lines. In such a case, since the connecting part between the branch line and the anchor bolt is Y-shaped, the covering cover attached thereto must also have three openings to allow the two branch lines and one anchor bolt to pass through. However, there were many problems in terms of functionality, workability, economy, etc., such as the opening angle between the two branch lines was not necessarily constant and the mounting structure was complicated.

In view of these problems, the present invention has two branch wire insertion holes in one end face in the longitudinal direction of the cover body, which is hollow inside, and an anchor bolt insertion hole in the opposite end face. , one branch line insertion hole is formed in an elliptical shape with a long diameter on the side of the other branch line insertion hole, and a dividing line is provided on one side of the cover body to cut each of the branch line insertion holes and the anchor bolt insertion hole, and the splitting The present invention provides a covered cover in which both side edges of the cover main body along the line are removably connected to each other via an engaging pin, and thereby it is possible to easily respond to changes in the opening angle between the branch lines, and it is easy to use. It is designed so that it can be installed on.

An embodiment of the present invention will be described below with reference to the drawings. In the figure, reference numeral 1 denotes a cover body with a hollow interior, and 2
Two branch wire insertion holes 2 and 12 are provided, and an anchor bolt insertion hole 3 is provided on the opposite end surface. In this case, one of the branch line insertion holes 2 is circular, while the other branch line insertion hole 12 is shaped like an ellipse with a longer diameter on the side of the branch line insertion hole 2. A dividing line 4 for cutting out each branch line insertion hole 2, 12 and anchor bolt insertion hole 3 is provided on one side of the cover body 1 in the same plane, and the cover body 1 can be opened and closed along the dividing line 4. That's what I do. Further, a pair of flanges 5a and 5b are provided oppositely on both side edges of the cover body 1 along the dividing line 4, and one of the flanges 5a and 5b is provided oppositely.
An appropriate number of tongue-like pieces 6, 6 are provided extending from the tip edge of b in a direction beyond the other flange piece 5a, and each tongue-like piece 6, 6 has a small diameter 7 and a small hole 7 of the cover body 1. A small hole 8 is also provided at a position corresponding to . 9 indicates both small holes 7 and 8
This is an engagement pin that is inserted from the outside of the cover body 1 and engaged with the cover body 1. Further, a locking pawl 10 and an engagement hole 11 for locking the locking pawl 10 are provided opposite to each other at a position close to the branch line insertion hole 2 and a position close to the anchor bolt insertion hole 3 of the collar pieces 5a, 5b. On the other hand, the branch line insertion hole 12 is covered with a thin, pleated lid 13 that extends from its inner peripheral surface in a double-folded manner.
It should be noted that the end edges of each of the branch line insertion holes 2, 12 and the anchor bolt insertion hole 3 are reinforced by providing a collar portion 14 around them.

An example of the use of the cover A constructed in this manner will be described with reference to FIGS. 9 and 10. 16 is a utility pole; 17a and 17b are branch wires each having one end fixed to the top of the utility pole 16 at a predetermined interval; 18 is an anchor bolt planted on the ground; a hook-shaped hook is attached to the other end of each of the branch lines 17a and 17b; An engaging portion 19 is provided and connected in a Y-shape, and this is expanded to a predetermined degree of inclination as shown in FIG. In this case, each branch line 17a, 17b has branch line covers 20a, 2.
0c, and a bolt cover 20b is attached to the anchor bolt 18, and each branch line cover 20
Flange portions 21 are provided around the tips of the bolt covers a, 20c and the bolt cover 20b, respectively. In this way, the covering cover A opens the cover main body 1 along the dividing line 4, and each branch line insertion hole 2, 12 has each branch line 17a,
17b, and the bolt cover 20b of the anchor bolt 18 is fitted into the anchor bolt insertion hole 3. In this state, the dividing line 4 is closed and each locking pawl 10 is inserted into the engagement hole 11.
Then, the engagement pins 9 are inserted and attached to each of the small diameters 7 and 8. Thus, the covering cover A has the branch line cover 20a and the bolt cover 20b in the tenth position.
As shown in the figure, each of the flanges 21, 21 located inside the cover body 1 fixes the mounting position of the covering cover A and prevents it from shifting. And branch line insertion hole 1
2 is oval, so both branch lines 17a, 17b
Even if the opening angle of both branch lines 17a and 17b is uncertain,
can be inserted into each branch line insertion hole 2, 12.

As is clear from the above description of the embodiments, the cover according to the present invention can be used even if there is a variation in the opening angle between the two branch lines. There is no hassle when you select the one you want to use. Therefore, it has great economic merits, such as being suitable for mass production and simplifying inventory management. Further, since it can be easily attached to the connecting part between the branch line and the anchor bolt, it has the advantage of improving the efficiency of the attachment work, and is extremely useful in practice.
