).

FIG. 1 is a plan view of a conventional overhead cable line with two parallel cables, with cables omitted.

In the figure, Pl, P2. P3 is a telephone pole, A is a suspension wire that suspends the cable with a cable ring below, B is hanging hardware, C is a scaffolding bolt, and D is a connecting lead pipe (for CCP cables, it is a connecting terminal box).

), E indicates a terminal box. When rebuilding intermediate pole P2, temporarily fasten the drop-in line using the cable suspension line (support line) A, and remove the suspension line (support line) A from the suspension hardware B installed on the utility pole and let it hang. After that, use a crane truck etc. to remove utility pole P2.
If the suspension wire A is a parallel two-strip or three-strip construction, the spacing between the suspension wires is only about 30 crn, so when the utility pole is operated, the scaffolding bolt C of the utility pole P2 is connected to the suspension wire A.
It may come into contact with the wires or cables, resulting in poor workability and the risk of damaging the cables.

Therefore, there is a drawback that the work must be carried out by pulling the left and right suspension wires A, etc. that sandwich the utility pole P2 with ropes, and widening the distance as necessary.

In order to eliminate the drawbacks of the conventional method, the present invention fixes almost inverted U-shaped hook bolts for temporary fixing of lead-in wires near both ends of the top surface of a rectangular metal plate board, and attaches cable suspension wires to the left and right ends of the bottom surface of the board, respectively. An L-shaped long suspension member with a hole for removably fixing the suspension hardware that fixes the cable, and an L-shaped short suspension member are removably fixed so that the spacing between them is approximately three times the spacing between parallel cables. It is characterized by consisting of a cable hanging hardware that is detachably fixed to the separator body and the long and short suspension members, and its purpose is to temporarily fasten the lead-in wires, and to provide spacing between parallel suspension wires (support wires). keep it wide,
The objective is to obtain a tool with a simple structure that can facilitate the removal and installation of utility poles using a crane vehicle or the like.

The present invention will be explained based on the drawings.

On the other hand, the self-holding type cable hanging hardware 5S12 has two rectangular short plates 12-1, 121 with protrusions in the axial direction on both inner edges, and the center of the plates 12-1, 12-1. Mounting bolt 9 and suspension wire fixing poles on the left and right) 12-2.1
2-2 is provided and configured.

The separator S shown in FIG. 6 is used to remove the utility pole when the utility pole has three striations.

That is, there is a case where there are lead-sheathed cables suspended from cable rings on the left and right sides of a utility pole, and a CPS cable is located below one of the lead-sheathed cables.

Hanging hardware for general cables Lll is for connection with suspension wires.
The self-holding cable suspension hardware 5S12 is used to hold a support wire integrally provided on the upper part of the CPS cable.

Remove the general cable hanging hardware L13) 13B from the arc-shaped bolt 13-2, or rotate it to the tip and loosen the connection with the hardware body 13-1.

Next, the order of removing utility poles using the separator of the present invention will be explained.

To attach the separator to the suspension wire (support wire), attach the general cable suspension hardware L attached to the long suspension member 2, the self-holding cable suspension hardware SS, and the one side closest to the utility pole to be rebuilt. The suspension wires removed from the suspension hardware are mated, and then the suspension wires are removed from the suspension hardware on the opposite telephone pole and mated to the general cable suspension hardware L13 attached to the short suspension member 3.

A plan view of this state is shown in FIG.

At this time, the work of moving the hanging line can be done easily and safely by suspending the hanging line with a crane or hemp rope and adjusting it while adjusting.

Finally, the drop-in line that is tied to the utility pole is removed from the hanging hardware on the utility pole and temporarily fastened to the hook bolts 4 and 5.

As a result of the above work, the utility poles became empty poles, and the suspended suspension wires (support wires) were maintained at a distance of about 60 cm, which would not interfere with the utility pole reconstruction work, and were held by separators.

The length of approximately 60 cm is due to the length of the lifeline, which makes it easier to remove and attach the suspension line.

If the area is narrow, removal work is not necessarily easy. However, approximately three times the cable span spacing is suitable for work.

Therefore, utility poles can be smoothly removed and reinstalled without coming into contact with suspension wires (support wires) and cable drop-in lines, which prevents damage to cables and drop-in lines, further ensuring safety, saving labor, and making it easy to install. Can work.

In addition, reinstallation of the suspension line (support line) to the new utility pole (hanging frame) is as follows:
First, the suspension wires (support wires) are removed from the separator suspension hardware to release the spacing, and then the usual method is used.

As mentioned above, the separator of the present invention can be used not only to rebuild the intermediate pole in its original position, but also to rebuild (relocate) it by changing its position in the direction of the railway line using the same procedure, or to install it between existing utility poles. It can be applied to newly established.

Also, as shown in Fig. 8, when rebuilding the stud P4 used at the corner of the overhead line, separators S are attached to the suspension wires A and A in the same manner as described above, and then the suspension wire A is
, A from the suspension hardware on the stud P4 and replace the horizontal branch line F supporting the stud P4 with the hook bolt 4 (or 5) of the separator, the stud P4 becomes free and can be easily removed.

Rebuild a new stud in its place, replace horizontal branch line F from separator S, support stud P4, and suspend line A.

A can be removed from the separator S and fixed to a hanging hardware provided on a utility pole.

In the above description, a case has been described in which the general cable suspension hardware L and the self-holding type cable suspension hardware SS are fixed to the long and short suspension members.

However, the suspension hardware L for general cables and the suspension hardware SS for self-holding cables can also be directly fixed to the board, and moreover, the suspension wires and CPS cables can be clamped and locked.

SD hanging hardware (not shown) can also be used.

The number and type of hanging hardware can be changed freely depending on the number and type of cables attached to the utility pole.

Generally, if the configuration shown in Figure 6 is used, there is no need to remove utility poles or install new ones underground as separators, no matter where you bring them.

As explained above, the separator for rebuilding and newly installing utility poles according to this invention has a substantially U-shape, and is connected to the base plate, long and short suspension members, and various removable suspension hardware are attached to the suspension parts. Furthermore, hook bolts are attached to both ends of the board, and by keeping the suspension lines (support lines) that run parallel to each other at a distance wider than the pole diameter, cable damage can be prevented and operations such as removing and installing new poles can be carried out safely. , producing easy and labor-saving effects.
