Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cable-carrying wire car for use in overhead line construction of communication cables and the like.

[0002]

[Prior Art]

 The communication cable has a structure in which a plurality of electric wires are bundled.To connect this communication cable to a utility pole, first hang a suspension wire made by twisting steel wire on the utility pole, and then The communication cable is hung on the suspension line. By the way, in communication cables, an extremely large number of electric wires are being bundled as the communication capacity increases. For this reason, it is difficult and complicated to suspend a heavy communication cable because many electric wires are bundled in a suspension line that is installed on a utility pole.

Therefore, an SS cable in which a fishing line and a communication cable are integrally formed has been used. In order to install this SS cable on a utility pole, the SS cable 102 wound around the cable drum 101 was pulled out as shown in FIG. 4, and the rope attached to the end of the SS cable 102 was attached to the utility pole 103. The tip is pulled by a winch or the like through the gold wheel 104. At this time, the overhead line is being secured while securing the required ground clearance. If the rope or SS cable 102 breaks during overhead line construction, it may hang down on the road and obstruct traffic.

For this reason, a hanging wheel 110 for preventing sagging as shown in FIGS. 5 and 6 is used so that the rope or the SS cable 102 does not sag even if the rope or the SS cable 102 is cut during overhead line construction. This gold wheel 110 includes three guide rollers 106 attached to the substrate frame 105 and two holding rollers attached to a holding plate frame 107 provided on the substrate frame 105 so as to be openable and closable via compression springs 108. It consists of 109 and. The holding plate frame 107 is opened, the SS cable 102 is passed between the holding roller 109 and the guide roller 106, and then the holding plate frame 107 is closed. By doing so, even if the SS cable 102 is cut by the pressing roller 109 that receives the biasing force of the compression spring 108, it does not go back and hang down.

[0005]

[Problems to be solved by the device]

 However, in such a conventional hanging wheel 110 for preventing sagging, the biasing force of the compression spring 108 is constantly exerted on the pressing roller 109, and therefore, even when the SS cable 102 is towed. It means that it is biased. As a result, the biasing force of the compression spring 108 acts as a resistance and the SS cable 102 cannot be pulled smoothly, and a large pulling force is required.

An object of the present invention is to provide a cable overhead wire car that can smoothly pull the cable with a small pulling force when the communication cable or the like is installed in the overhead line.

[0007]

[Means for Solving the Problems]

 In order to achieve such an object, in the present invention, a receiving member in contact with a cable to be lined, and a cable that cooperates with the receiving member, which is arranged so as to face the receiving member, are provided. A holding member that holds the holding member and a sliding mechanism that holds the holding member slidably in an oblique direction with respect to the pulling direction of the cable are provided.

[0008]

[Action]

 The rope attached to the tip of the cable is pushed up diagonally upward from the holding member, and is inserted between the holding member and the receiving member. When the rope is pulled, the cable is also inserted between the holding member and the receiving member, and the tip of this cable is pulled by a winch or the like. At this time, the cable is pulled between the receiving member and the pressing member, but the pressing member is slid upward by the sliding mechanism. When the holding member slides diagonally upward, the space between the receiving member and the holding member expands, and the cable is pulled smoothly without receiving the resistance of the holding member.

[0009]

【Example】

 Hereinafter, the present invention will be described with reference to the drawings. 1 to 3 are views showing an embodiment of a cable car for a cable overhead wire according to the present invention.

In FIGS. 1 and 2, reference numeral 1 is a substrate frame in which a connecting shaft 3 is attached between a pair of metal steel plates 2a and 2b, and a nylon support roller 4 is supported on the substrate frame 1. Two pieces are rotatably attached via a shaft 5. The support roller 4 has a substantially drum shape as shown in FIG. 3, and the SS cable 6 is guided and positioned in the recessed portion 4a at the substantially center. A metal plate-shaped receiving member 7 is welded onto the connecting shaft 3, and a rubber sheet 8 is attached to the upper surface of the receiving member 7. The SS cable 6 to be pulled is located on the rubber sheet 8. However, since the rubber sheet 8 is provided slightly below the recessed portion 4a of the support roller 4, when the SS cable 6 is pulled. Does not come into strong contact with the rubber sheet 8. Four guide shafts 10 are provided upright on both end sides of the substrate frame 1 via support brackets 9.

A holding plate frame 11 is removably provided on the substrate frame 1 via a screw type connecting tool 12, and the holding plate frame 11 is connected to a pair of metal plate members 12a and 12b and a connecting member provided therebetween. It consists of a shaft 13. A holding member 14 that holds the SS cable 6 in cooperation with the receiving member 7 is slidably attached to the holding plate frame 11 obliquely with respect to the pulling direction A of the SS cable 6. The pressing member 14 is a metal plate member disposed so as to face the receiving member 7. A rubber member 15 is attached to the lower surface side of the pressing member 14, and the rubber member 15 has a surface facing the receiving member 7. Has a recess 15a formed along the pulling direction A, and guides and positions the SS cable 6 in the recess 15a.

The pressing member 14 is slidable with respect to the pulling direction A by the sliding mechanism 16 as described above. That is, the support arm member 17 is fixedly mounted on the upper surface of the pressing member 14, and two guide shafts 18 penetrate and are fixed to the upper side of the support arm member 17 at both ends of each guide shaft 18. A guide roller 19 is rotatably attached. The guide rollers 19 are loosely fitted in a pair of cross girder members 20 provided obliquely with respect to the pulling direction A inside the pair of holding plate frames 11. Further, a pair of overhanging members 21 each having a substantially L-shaped cross section and extending toward the cross beam member 20 are attached to a substantially middle portion of the supporting arm member 17, and a cross beam is attached to a tip of the overhanging member 21. A slidable member 22 made of high-molecular polyethylene capable of sliding contact is attached to the lower surface of the member 20. Therefore, the supporting arm member 17 is slid and guided smoothly along the transverse beam member 20 via the guide roller 19 and the slidable member 22. A supporting piece 23 is fixed to the upper end of the holding plate frame 11, and a hanging metal fitting 24 is fixed to the supporting piece 23.

In order to wire the SS cable 6 on the utility pole, a hanging member is hooked on a hook member provided on the utility pole, and the gold wire for the cable overhead wire is attached to the utility pole. The SS cable 6 is pulled out from a cable drum (not shown), and the SS cable 6 is passed through the wire car for the cable overhead wire. That is, a rope (not shown) attached to the end of the SS cable 6 is pushed upward and diagonally to the right from the left end side in FIG. 2 while pushing up the holding member 14 and the receiving member. Insert between 7 and. When the rope is pulled, the SS cable 6 is also inserted between the holding member 14 and the receiving member 7, and the tip of the SS cable 6 is pulled by a winch or the like. At this time, the SS cable 6 is pulled between the receiving member 7 and the pressing member 14. Since the pulling direction A at this time is from the left end side to the right direction in FIG. 2, the pressing member 14 is a sliding mechanism. 16 slides diagonally upward to the right. When the holding member 14 is slid rightward and upward, the space between the receiving member 7 and the holding member 14 is expanded, and the SS cable 6 is smoothly pulled without receiving the resistance of the holding member 14. In this way, the SS cable 6 is installed on the power pole while ensuring the ground clearance.

By the way, if the rope or the SS cable 6 breaks during towing, the SS cable 6 tends to return due to its own weight. That is, the SS cable 6 inserted between the pressing member 14 and the receiving member 7 is likely to return to the left from the right end side in FIG. When the SS cable 6 goes back, the SS cable 6 causes the pressing member 14 to slide diagonally downward to the left. At this time, the distance between the holding member 14 and the receiving member 7 becomes narrow, and the SS cable 6 is held so as to fit into the holding member 14 and the receiving member 7. For this reason, the SS cable 6 is held and fixed only by returning a little, and then it does not hang down on the road and obstruct the passage.

Here, the diameter of the SS cable 6 tends to become larger and larger with the increase of the communication capacity in recent years. When the SS cable 6 having such a large diameter is installed over the wire, the biasing force of the compression spring is further increased in the conventional gold wheel, and the SS cable 6 cannot be pulled more smoothly. However, in the gold wire car for cable overhead wire according to the present invention, the pressing member 14 slides and the distance between the pressing member 14 and the receiving member 7 is expanded, and even if the SS cable 6 having a large diameter is changed. It can be smoothly towed.

Further, since the diameter of the SS cable 6 is large and the diameter of the rope attached to this tip is small, when this is passed through the conventional gold wheel 110, the gold wheel 110 is set on the way due to the difference in diameter. Although there is a need to correct it, in the wire car for cable overhead wire according to the present invention, since the sliding mechanism 16 is provided, it is not necessary to perform such setting again.

[0017]

[Effect of the device]

 As described above, according to the present invention, the holding member that holds the cable in cooperation with the receiving member is slidable in the oblique direction with respect to the pulling direction of the cable by the sliding mechanism. As a result, the space between the receiving member and the pressing member expands, and this cable is smoothly pulled without receiving the resistance of the pressing member and without returning, so that a small traction force is required.
