Description

[Detailed description of the invention]

[0001]

[Industrial applications]

 The present invention relates to a wire winding device, and more particularly, to a wire winding device for winding a wire connected to a cable and laying the cable in a cable laying operation.

[0002]

[Prior art]

 For cable erection work for laying cables between telephone poles, generally, a cable working vehicle equipped with a cable reel wound with a cable to be erected, and a rope connected to the cable to feed out the cable wound on the cable reel. A rope winding work vehicle equipped with a rope winding device is used. The rope winding device includes a rope winding reel rotatably mounted for winding the rope, and a driving device for rotating the rope winding reel.

In the cable erection work, a cable work vehicle is arranged around one side of an adjacent utility pole, a rope winding work vehicle is arranged on the other side of the utility pole, and a rope winding reel of the rope winding work vehicle is arranged. The rope is fed out of the cable and wrapped between adjacent utility poles, and the end of the rope is connected to the end of the cable wound on the cable reel. Then, when the driving device is operated, the rope take-up reel is driven to rotate, and the rope is taken up by the rope take-up reel, and a cable is laid instead of the rope hung between utility poles.

[0004]

[Problems to be solved by the invention]

 However, the rope take-up reel has a configuration in which the rope is wound around a cylindrical body having the same diameter, and when the length of the cable installed between the utility poles increases, the length of the cable pulled between the utility poles increases. As the length increases, the tension on the rope increases. Further, the driving device is configured to rotate the rope take-up reel with a substantially constant torque. When the rope is wound on the rope take-up reel, the winding diameter of the outermost wound rope ( Hereinafter, it will be referred to as “winding effective diameter”.), And the winding tension for winding the rope will be reduced. As a result, when the tension acting on the rope and the winding tension for winding the rope are the same, the rope cannot be wound, and the work of laying the cable stops.

[0005] Therefore, a rope winding device provided with a speed change mechanism for changing a rotating torque for rotating the rope winding reel in accordance with the effective winding diameter has been proposed, but a problem that costs are greatly increased. Occurs.

The present invention has been made in view of such a problem, and in the cable laying work, the rotation of the rope take-up reel stops even when the length of the laid cable increases. It is an object of the present invention to provide an inexpensive wire rod winding device that can continuously perform cable laying work without any need.

[0007]

[Means for Solving the Problems]

 In order to solve the above-mentioned problem, the wire winding device of the present invention is provided with a plurality of cylinders which are rotatably provided for winding the wire, and which are partitioned by a partition plate projecting outward in the radial direction and arranged in the left-right direction. (E.g., the rope winding reel 20 according to the embodiment) having a reel (e.g., the large-diameter trunk portion 23 and the small-diameter trunk portion 25 according to the embodiment), and a driving device that rotationally drives the reel. And configure. Here, the partition plate is configured to have a wire passage groove through which the wire is wound so that the wire wound around any of the plurality of trunks is continuously wound around another adjacent trunk.

According to the wire winding device having the above configuration, when the reel is driven to rotate by the driving device and the wire wound around one of the plurality of body portions is passed through the wire passage groove, the wire is wound. And is wound around another trunk adjacent to the trunk. As a result, the wire can be continuously wound from one torso to the other adjacent torso, and when the reel is driven to rotate at a substantially constant torque, a plurality of torso parts can be wound. Even if the winding diameter of the wire wound on the outermost side of the wire wound around one of them increases and the winding tension for winding the wire decreases, the wire is wound around the other body adjacent to it. By winding, the winding tension can be increased, and the winding operation of the wire is not interrupted due to insufficient winding tension, and the wire laying operation can be performed continuously.

In the wire winding device having the above configuration, it is preferable that the plurality of body portions forming the reel have different diameters.

According to the wire winding device having the above-described configuration, first, the wire is wound around a large-diameter body of the plurality of bodies, and the winding diameter of the wire on the body gradually increases, and the reel is wound. When the take-up tension for winding the wire is reduced, the wire is passed through the wire passage groove, wrapped around another adjacent body, and wound. As a result, the winding tension can be easily increased even when the diameter of the other body is smaller than or the same as the diameter of the body that was wound initially.

[0011] In the wire winding device having the above-described configuration, one or more wire rod passage grooves are provided in the partition plate, extend radially outward from near the surface of the trunk portion, and open at the outer periphery of the partition plate. You may.

According to the wire winding device having the above configuration, when the wire is passed from one adjacent body to the other body, the wire is passed through the wire passage groove. Here, since the wire passage groove is configured to extend radially outward from near the surface of the trunk portion in the partition plate and open at the outer periphery of the partition plate, the diameter of the wire rod wound around one of the trunk portions is formed. The wire can be passed through the wire passage groove from the same position as the direction. As a result, it is possible to prevent a situation in which the contact resistance between the wire wound around the trunk and the surface of the trunk or the contact resistance between the wound wire decreases and the wire slips on the trunk.

[0013]

[Embodiment of the invention]

 Hereinafter, a preferred embodiment of the present invention will be described with reference to FIGS. This embodiment shows an embodiment of a rope winding work vehicle provided with a wire winding device for performing cable erection work for laying a cable between utility poles. First, before describing the wire winding device of the present invention, a rope winding work vehicle equipped with the wire winding device will be described. As shown in FIG. 1, the rope winding work vehicle 1 can run with wheels at the front of a vehicle body 3 and is based on a truck vehicle having a driving cabin 5 at the front.

Next, the wire winding device 10 will be described. The wire winding device 10 includes a base 11 mounted on the front of the vehicle body behind the driving cabin 5, a rope winding reel (reel) 20 rotatably mounted on the base 11, And a driving device 40 for rotatingly driving the take-up reel 20. As shown in FIG. 2 (a), the rope take-up reel 20 is a cylindrical large-diameter trunk portion which is partitioned by three partition plates 21 protruding outward in the radial direction and arranged in the left-right direction. 23 and a small-diameter trunk 25 having a smaller diameter than the large-diameter trunk 23. An annular partition plate 21 is attached to both left and right ends of the large-diameter body 23, and an annular partition plate 21 is attached to the right end of the small-diameter body 25. The three partition plates 21 have the same outer diameter.

Here, FIG. 2B is a cross-sectional view of a portion corresponding to the AA arrow in FIG. 2A, and as shown in FIG. The attached partition plate 21 is configured to be disposed at both ends of four fan-shaped partition plate portions 21a via wire rod grooves 27. The wire rod passage groove 27 is formed so as to extend from the surface of the large-diameter trunk portion 23 to the outside in the radial direction of the partition plate 21 and open at the outer periphery of the partition plate 21. A reel shaft 29 is inserted through the center of the rope take-up reel 20, and the reel shaft 29 is connected to the large-diameter trunk portion 23 and the small-diameter trunk portion 25 via partition plates 21 attached to both right and left ends of the rope take-up reel 20. Connected and integrated. Both ends of the reel shaft 29 are rotatably attached to the base 11 shown in FIG.

As shown in FIG. 1, a drive device 40 is mounted on the vehicle body 3 near the base 11. The driving device 40 is connected to the reel shaft 29 of the rope take-up reel 20 via a drive force transmission mechanism (not shown), and keeps the rope take-up reel 20 substantially constant regardless of the magnitude of the load acting on the rope take-up reel 20. It is configured to rotate with the driving torque.

The rope take-up reel 20 is not limited to the one described above, and a small-diameter body 25 may be further provided at the left end of the large-diameter body 23 as shown in FIG. . In this case, it is assumed that the partition plate 21 attached to the left end of the large-diameter trunk portion 23 is composed of a partition plate portion 21a and a wire rod groove 27 as shown in FIG. Further, as shown in FIG. 3B, the outer diameter of the small-diameter trunk 25 may be substantially the same as or larger than that of the large-diameter trunk 23.

Next, a cable erection work for erection of the cable K between the adjacent utility poles P1 and P2 using the wire winding device 10 will be described. In the cable erection work, as shown in FIG. 1, first, a cable work vehicle 53 is arranged around the electric pole P1 of the adjacent electric poles P1 and P2, and the rope winding work vehicle 1 is arranged on the electric pole P2 side. The rope R is wound around the large-diameter trunk 23 shown in FIG. 2 (a), and a cable reel 55 around which the cable K is wound is rotatably mounted on the cable working vehicle 53. It is assumed that

When the cable working vehicle 53 and the rope winding work vehicle 1 are disposed at the work site, the rope winding reel 20 mounted on the rope winding work vehicle 1 is rotated to unwind the rope R, and the rope R is pulled out. The cable R is wound between the electric poles P1 and P2, and the end of the rope R is connected to the end of the cable K wound around the cable reel 55 via the connection member 57. Then, the driving device 40 of the rope winding work vehicle 1 is operated. When the driving device 40 is operated, the rope take-up reel 20 rotates with a substantially constant driving torque, and pulls and pulls the rope R that is fed out in the arrow Y direction.

When the rope R is taken up by the rope take-up reel 20, the cable reel 55 rotates and the cable K is fed out, and the cable K is replaced by the cable K instead of the rope R stretched between the adjacent utility poles P1 and P2. Is stretched. Here, as the installation length of the cable K installed between the utility poles P1 and P2 (hereinafter referred to as “cable installation length L”) increases, the length of the cable K pulled between the utility poles P1 and P2 increases. Then, the tension Fr acting on the rope R from the cable K is increased. Also, since the driving device 40 is configured to rotate the rope take-up reel 20 with a substantially constant torque, the rope R is attached to the large-diameter trunk portion 23 of the rope take-up reel 20 shown in FIG. Is wound, the winding diameter of the outermost wound rope R (hereinafter referred to as “effective winding diameter φD”) gradually increases, and as a result, the winding tension Fm for winding the rope R is increased. Lower.

Here, FIG. 4 is a graph showing the relationship between the winding tension Fm and the tension Fr acting on the rope R with respect to the cable erection length L. As shown in the figure, when the length L of the cable overhead wire increases, the winding tension Fm decreases and the tension Fr acting on the rope R increases. When the cable overhead wire length L becomes L2, the magnitude of the winding tension Fm and the tension Fr acting on the rope R become the same, and the winding of the rope R becomes difficult. Then, when the cable overhead wire length L becomes L1 shorter than L2, the rope R is replaced from the large-diameter trunk 23 shown in FIG. That is, as shown in FIG. 2, the rope R wound around the large-diameter trunk 23 shown in FIG. 2 is passed through the wire rod groove 27 shown in FIG.

When the rope R is switched from the large-diameter trunk 23 to the small-diameter trunk 25, the winding tension Fm acting on the rope R increases. This is because the rope take-up reel 20 rotates with a substantially constant rotational torque, and the diameter of the small-diameter trunk 25 is smaller than that of the large-diameter trunk 23. More specifically, as shown in FIG. 4, the winding tension Fm increases from F1 corresponding to the point T1 in FIG. 4 to F2 corresponding to the point T2. As a result, as shown in FIG. 1, the rope take-up reel 20 rotates and continues to wind the rope R, and the rope take-up reel 20 keeps the rope R until the cable overhead wire length L becomes the distance between telephone poles, ie, Le. Will continue to be wound. The winding tension F3 when the cable overhead wire length L is the distance between poles Le is larger than the tension F4 acting on the rope R as shown in FIG. Never.

Here, when the rope R is changed from the large-diameter trunk portion 23 to the small-diameter trunk portion 25 and the rope R is wound by the small-diameter trunk portion 25, as shown in FIGS. The size of the winding diameter (hereinafter referred to as “effective winding diameter”) of the outermost rope R among the ropes R wound around the small-diameter trunk portion 25 will be considered. When the effective winding diameter of the rope R wound around the large-diameter trunk portion 23 when the cable overhead wire length L is L1 is φD, the rope R is wound around the small-diameter trunk portion 25 when the cable overhead wire length L is Le. The wound effective diameter of the rope R thus obtained is φS, and there is a relationship of φD> φS. This is because, when the length R of the cable overhead is L1, the rope R is replaced and the rope R is wound by the small-diameter trunk 25, and the effective diameter of the rope R wound around the small-diameter trunk 25 is large. This means that the rope R must be used so that it is always smaller than the effective winding diameter φD of the rope R wound around the portion 23. However, it is a precondition that the winding tension Fm when the cable overhead wire length L is Le is larger than the tension Fr acting on the rope R.

As a result, as shown in FIG. 3B, the rope winding reel 20 in which the outer diameter of the small-diameter trunk 25 is equal to or larger than that of the large-diameter trunk 23 is used. When the rope R is switched from the large-diameter trunk portion 23 to the small-diameter trunk portion 25 and wound around the small-diameter trunk portion 25, the winding diameter of the rope R wound around the large-diameter trunk portion 23 is smaller than the effective diameter φD1. As in the case of the rope take-up reel 20 shown in FIG. 2, the rope R must be used so that the winding effective diameter φS1 of the rope R wound around 25 is always small. However, it is a precondition that the winding tension Fm when the cable overhead wire length L shown in FIG. 4 is Le is larger than the tension Fr acting on the rope R.

As described above, by passing the rope R through the wire rod groove 27 provided in the partition plate 21, the rope R wound around the large-diameter trunk 23 is continuously wound around the small-diameter trunk 25. It can be done. Further, by winding the rope R around the small-diameter trunk portion 25 having a smaller diameter than the large-diameter trunk portion 23, the winding tension Fm can be increased, and the winding tension Fm may be insufficient. Thus, the cable can be continuously laid between the utility poles P1 and P2 shown in FIG. 1 without interrupting the cable erection work.

As shown in FIG. 1, when the cable K installed between the utility poles P1 and P2 is removed, the cable K connected to the utility pole P2 is opened and connected to the rope R, and the utility pole P1 is connected to the utility pole P1. When the rope R is wound up by rotating the rope take-up reel 20 in a state where the connected cable K is opened to prevent the cable R from hanging down, the winding tension Fm becomes smaller than the winding amount of the rope R. Accordingly, the tension Fr acting on the rope R becomes smaller than the winding tension Fm, so that the winding tension Fm does not become insufficient. Therefore, the cable K can be removed while the rope R is wound around the large-diameter trunk portion 23 without changing the rope R from the large-diameter trunk portion 23 to the small-diameter trunk portion 25 shown in FIG. .
