Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an optical cable winding machine which is installed on an overhead ground line of an overhead power transmission line so as to be able to travel and winds an optical cable around the overhead ground line. Also, the present invention has a feature in a traveling mechanism for enabling stable winding of the optical cable around the portion.

[0002]

2. Description of the Related Art In general, an overhead power transmission line is provided with an overhead ground wire for lightning protection. An optical cable for constructing an optical communication network is laid using the overhead ground wire. ing. 2. Description of the Related Art Conventionally, an optical fiber composite overhead ground wire (OPGW) in which an optical cable is housed in an aluminum tube arranged at the center of a metal stranded wire layer constituting a current path has been widely used in view of the reliability of optical fiber protection and the like. However, recently, a direct winding method of spirally winding an optical cable around an overhead ground wire and laying the same has also been adopted.

[0003] The work of directly winding an optical cable around an overhead ground wire is performed by pulling and running an optical cable winding machine suspended on the overhead ground wire with a rope. For example, as shown in FIG.
When the winding machine main body 2 is towed by the rope 3 as the optical cable winding machine 1 of this type, the rotation of the roller 5 riding on the overhead ground wire 4 is transmitted to the revolving frame 7 via the gear mechanism 6. Then, the turning frame 7 turns around the overhead ground wire 4, and the optical cable 9 is paid out from a bobbin 8 that turns integrally with the turning frame 7, so that the optical cable 9 is spirally wound around the overhead ground wire 4. Is known.

[0004] By the way, there is a gradient in an overhead ground wire stretched between power transmission towers, and particularly when the construction is steep in the vicinity of the tower and when the overhead ground wire is stretched between towers having a height difference. Are steeper and more steep ascents or steep downhills for the optical cable winder traveling on those steep slopes. When winding the optical cable 9 uphill,
If the rope that is pulling and running the optical cable winding machine 1 is loosened even temporarily, the optical cable winding machine 1 retreats, the roller 5 rotates in the reverse direction, and the bobbin 8 turns around the optical cable 9 in the opposite direction, There is a problem that the optical cable 9 wound around the overhead ground wire becomes loose. Further, in the case of a downhill, the optical cable wrapping machine 1 runs out of control, causing a problem that control becomes impossible. As a countermeasure,
The brake is applied to the running rollers 5, 5 '.

[0005]

However, simply applying a brake to the two rollers 5, 5 'cannot provide a sufficient gripping force with respect to the overhead ground line. Work was required to prevent loosening. In addition, there is a problem that work cannot be performed on a downhill as it is, so that work must be performed from the opposite direction (that is, uphill).

SUMMARY OF THE INVENTION The present invention has been made in order to eliminate the above-mentioned conventional problems, and has a structure capable of obtaining a sufficient grip force with respect to an overhead ground wire. An object of the present invention is to provide an optical cable winding machine.

Applies the brake torque as described above,
The brake is applied to the rotation of the bobbin 25, and the optical cable 9 is wound around the overhead ground wire 4 with an appropriate tension.

The traveling pulleys 26, 40 on the front side
Is applied with a brake torque by a brake shoe 102, and a disengagement prevention roller 41 urged upward by a tension spring 105 and pressed against the lower surface side of the overhead ground wire 4 pulls the upper surface side of the overhead ground wire 4 through 40, and a brake by the built-in brake device is applied to the rotation of the slip-off prevention roller 41. A brake torque by the brake device 106 is applied to the traveling pulley 56 on the rear surface side, and a disengagement prevention roller 57 urged upward by the compression spring 119 and pressed against the lower surface side of the overhead ground wire 4 has an overhead ground. The upper surface of the wire 4 is pressed against the traveling pulley 56, and the brake is also applied to the rotation of the detachment prevention roller 57. Therefore, a sufficiently large grip force with respect to the overhead ground wire 4 can be obtained in both the front and rear portions.

As described above, a sufficiently large brake torque acts on each of the pulleys 26, 40, 56 and the slip-off prevention rollers 41, 57, and the slip-off prevention rollers 41, 57 cause the overhead ground wire 4 to move.
Is strongly pressed against each of the pulleys 26, 40, 56, so that a sufficiently large gripping force with respect to the overhead ground wire 4 can be obtained. Therefore, the optical cable wrapping machine 21 is
Can be self-maintained even at a steeply erected location, without slipping down the slope, and always traveling according to the towing of the tow rope 22. Thus, when the optical cable 9 is wound around an uphill portion of the overhead ground wire 4, the optical cable winding machine 21 does not retreat, and the pulleys 26, 40, and 56 rotate in reverse and the bobbin 2
There is no problem that the optical cable 5 turns around the optical cable 9 in the opposite direction and the optical cable 9 wound around the overhead ground wire 4 becomes loose. Therefore, the workability is improved without being forced to perform the work that does not loosen the tow rope 22 even for a moment. Further, in the case where the optical cable wrapping machine 21 runs out of control when the overhead ground wire 4 is installed on a downhill, there is no problem that the control becomes impossible, so that the work is performed from the opposite direction (that is, uphill). There is no need to perform complicated work such as the above, and the workability is improved in this respect as well.

In this embodiment, the detachment prevention rollers are provided on both the front side and the rear side, but may be provided on at least one side. In the embodiment, all the pulleys of the traveling pulley 26 and the traveling pulley 40 on the front side and the traveling pulley 56 on the rear side are provided with the brake devices. However, the brake device may be provided on at least one pulley. I just need. In the embodiment, the main body frame 23
Although two pulleys of the traveling pulley 26 and the auxiliary traveling pulley 40 are provided on the front side of the vehicle, only the traveling pulley 26 may be provided. Also, when a traveling pulley and an auxiliary traveling pulley are provided on the front side as in the embodiment,
This does not exclude the provision of the brake device only on the auxiliary traveling pulley side.

[0026]

According to the optical cable wrapping machine of the present invention, it is possible to prevent disengagement which is elastically pressed against the lower surface side of the overhead ground wire in opposition to at least one of the front and rear traveling pulleys attached to the main body frame. In addition to providing the rollers, a braking device for the traveling pulley and a braking device for the releasing rollers for applying a brake torque to the rotation of the traveling pulley and the slip-preventing rollers are provided, so that a sufficiently large brake torque for the rotation of the traveling pulley is obtained. The pull-out prevention roller strongly presses the overhead ground wire against each pulley side, and a sufficiently large grip force can be obtained for the overhead ground wire. Became possible. Therefore, when winding an optical cable around the erected part of an overhead ground line,
When the tow rope is loosened, the optical cable wrapping machine retreats,
The problem that the optical cable wound around the overhead ground wire is not loosened does not occur, and the problem that the optical cable winding machine runs away and cannot be controlled in the case of a downhill installation portion does not occur. As described above, the optical cable can be appropriately and efficiently wound around the overhead ground wire at the uphill and downhill installation locations of the overhead ground wire.
