Description

[Detailed Description of the Invention] The present invention relates to a device for crossing outdoor drop-in lines, leading hemp ropes, etc. when spanning overhead cables, over other existing wires that may be a hindrance.

When constructing an outdoor service line such as the one described above, it is often necessary to cross over other interfering wires.

Conventionally, when crossing service wires, etc. with other wires, we attached weights such as spanners to the service wires or hemp ropes and threw them over the interfering wires, or used a ladder truck. It depends on the method of exchanging words by climbing on the ladder. However, these methods are not only safe, reliable, and easy, but also have restrictions depending on the situation at the location where the wires are crossed. In this case, due to the friction and heat generated between the two parts, the insulation coating of the trouble wire is damaged due to continuous friction in one place, and it has been reported that the damage will cause problems over time. Many were seen.

In view of the above-mentioned points, the present invention provides a wire exchanging device that can safely, reliably, and easily cross over the interfering wire without coming into contact with it. Explain in detail.

1 to 3 show the main body of an embodiment of the present invention, in which 1 is a rod attachment member attached to the tip of a telescopic rod 2, and the retractable rod 2 has a cylindrical body made of a plurality of insulators. It is similar to a general telescopic rod in which a thin cylinder fits into a thick cylinder, and when the cylinders in contact with each other are fully extended, the engagement part is formed by a hole and a protrusion that fit between the cylinders. is provided to maintain the expanded state (not shown). 3 is a basic rod whose lower part is embedded and fixed in the rod mounting member 1 and whose upper part extends in all directions; 4 is a square frame rod whose four corners are fixed to the basic rod 3; and 5a and 5b are square frame rods 4.
It is a support rod extending upward from the four corners of the front pair of support rods 5a, and an L-shaped branch rod 6 protrudes outward from slightly below the upper end of the pair of front support rods 5a. A hook part for a lead-in line or the like is formed with the support rod 5a above this. A guide roller 7 having a plurality of hook insertion holes 8 in the radial direction is rotatably supported between the upper parts of the pair of rear support rods 5b, and a guide roller 7 with a plurality of hook insertion holes 8 provided in the radial direction at the center is rotatably supported. A magnet support plate 9 supporting a magnet 10 is attached to the magnet. The front support rod 5a below the protruding part of the branch rod 6, the rear support rod 5b below the magnet support plate 9, and the square frame rod 4 are coated with insulating tape or the like (indicated by dotted lines in the figure). ) has been applied.

4 to 6 show a hook 11, with a hook 12 protruding from the center that can be inserted into the hook insertion hole 8 of the guide roller 7, and one end of the hook 12 from the ground as shown in FIG. Operation string 1 with a length that can be operated
5 is attached, and the other end thereof is formed with a gripping part 14 such as a spirally wound lead-in line.

Next, a method of using the device of the present invention will be explained. As shown in Figure 7, service lines, etc. 16 to be spanned
Either make the tip of the front support rod 5 into a ring shape, or in the case of a wire that is difficult to bend into a ring shape, such as SD wire, attach another ring shape to the end.
a, and insert the hook hook 12 into any one of the hook holes 8 of the guide roller 7 with the operating string attachment part 13 of the hook 11 to which the operating string 15 is attached facing up, and A part is attracted to the magnet 10 to support the hook 11 so that it does not move. Next, the filament 17 that should intersect the lower end of the telescopic rod 2
The line 17 that should be placed on the ground directly below the front support rod 5a and extends upward from the top end of the rod to intersect
and the rear support rod 5b. Next, when you pull the operating string 15 on the ground, the hook 1
1 rotates away from the magnet 10, and the lead wire etc. gripping part 14 reliably grips and holds the ring-shaped part of the lead wire etc. 16 hung on the front support rod 5a. When the hook 11 rotates further, the hook hook 12 comes off the hook hole 8 of the guide roller 7 and is pulled down by the operating string 15. As the lead-in line etc. slides on the guide roller 7, the entire length passes over the filament 17 without contacting the filament 17 to be crossed. The hook 11 is removed from the ring-shaped part such as the lead-in line, and then the rod 2 is retracted and returned to its original state.

The same operation can be used for the laying of the lead hemp rope during the laying of overhead cables.

As explained above, by using the device of the present invention, it is possible to safely and reliably cross over the lead-in line etc. without causing it to come into contact with the existing wires that would be a hindrance, thereby causing damage to the obstructing wires due to friction. Moreover, since all you have to do is raise the rod from the ground and pull the operating cord, the work is simple and does not involve any danger. Moreover, it can also be used in almost any location.
