[0012] <Overall structure> The wire pulley attachment device of this embodiment is a device for attaching wire pulleys, which are used to extend a new communication cable to be newly installed between outdoor utility poles, to an existing communication cable already installed at a high altitude between the utility poles. The wire pulley is a metal pulley that has a hook that can be hooked onto an existing communication cable and can pull in the new communication cable while suspended from the existing communication cable by the hook. An existing communication cable already installed between utility poles is an example of an attachment target at a high altitude.

[0013] In this embodiment, "high place" is not limited to a place that is 2 meters or more above the ground, but also includes a place that is so high that a worker on the ground cannot reach it even if he or she stretches out his or her hand. Also, in this embodiment, "tip" refers to one end in the longitudinal direction, and "base end" refers to the other end in the longitudinal direction.

[0014] The configuration of the wire pulley attachment device 1 according to this embodiment will be described below. Fig. 1 is a diagram showing the configuration of the wire pulley attachment device 1 according to this embodiment.

[0015] As shown in FIG. 1, the wire pulley mounting device 1 comprises an operating rod 10, a first rope support part 20, an operating rope 30, and a belt-shaped member 40. The base end of the operating rod 10 is held by a ground worker, and the tip is detachably attached to an existing communication cable. The first rope support part 20 is connected to the tip of the operating rod 10. The operating rope 30 is movably supported by the first operating rope support part 20, and one end thereof via the first operating rope support part 20 is operated by a ground worker. The belt-shaped member 40 is connected to the other end of the operating rope 30 via the first rope support part 20, and is capable of holding a wire pulley 50.

[0016] In the wire pulley attachment device 1, the tip of the operating rod 10 is attached to an existing communication cable at a high place, and with the band-shaped member 40 holding the wire pulley 50, one end of the operating rope 30 is pulled by a worker on the ground, thereby lifting the wire pulley 50 up to the existing communication cable. Then, by operating the operating rope 30, the wire pulley 50 is attached to the existing communication cable.

[0017] <Configuration of the operating rod 10> The configuration of the operating rod 10 according to this embodiment will be described below. Fig. 2 is a diagram showing the configuration of the operating rod 10 according to this embodiment.

[0018] As shown in FIG. 2, the operating rod 10 includes a main body 11, an attachment portion 12, a connection portion 13, and a ring member 14.

[0019] The main body 11 is a rod-shaped member to be held by a worker on the ground, and has a circular cross section that can be carried by the worker. The main body 11 is made of a lightweight material, such as an electrically insulating plastic.

[0020] The mounting portion 12 is provided at the tip of the main body 11. The mounting portion 12 has a U-shape that allows it to be hung on and detached from an existing communication cable. Specifically, the mounting portion 12 is connected to the tip of the main body 11 and includes a first portion extending upward in the longitudinal direction of the main body 11, a second portion protruding from the tip of the first portion in the lateral direction of the main body 11, and a third portion extending downward in the longitudinal direction of the main body 11 from the tip of the second portion. The third portion of the mounting portion 12 also includes a portion extending upward in the longitudinal direction of the main body 11 from the tip of the second portion. The mounting portion 12 is formed so that it can support the weight of the wire pulley wheel mounting device 1 and the wire pulley wheel 50 even if the worker releases it while it is hung on the existing communication cable. The mounting portion 12 is preferably formed of, for example, metal in order to support the weight of the wire pulley wheel mounting device 1 and the wire pulley wheel 50.

[0021] The connecting part 13 is provided at the tip of the main body 11, and extends in the longitudinal direction of the main body 11, branching off from the first part of the mounting part 12. The connecting part 13 is located above the first part of the mounting part 12. A first rope support part is connected to the tip of the connecting part 13. The connecting part 13 is preferably made of, for example, metal, in order to support the weight of the wire pulley mounting device 1 and the wire pulley 50.

[0022] The ring member 14 is provided in the longitudinal center of the main body 11 so as to cover the circumferential direction. The ring member 14 is connected to the base end of the belt-shaped member 40. The ring member 14 has a plurality of rollers provided around its periphery. The plurality of rollers are rotatable so that the ring member 14 can move along the operating rod 10.

[0023] <Configuration of first rope support part 20> The configuration of the first rope support part 20 according to this embodiment will be described below. Fig. 3 is a diagram showing the configuration of the first rope support part 20 according to this embodiment.

[0024] As shown in FIG. 3, the first rope support part 20 includes a main body 21, a swivel structure part 22, and a pulley .

[0025] The main body 21 is connected to the connection part 13 of the operating rod 10 and is provided so as to extend in the longitudinal direction of the operating rod 10. The main body 21 is, for example, cylindrical, and houses the connection part 13 therein. The main body 21 and the connection part 13 are fixed and connected by a bolt that passes through both. The main body 21 is formed, for example, from metal. The main body 21 is formed to a length such that when the attachment part 12 of the operating rod 10 is hung on the existing communication cable and the operating rope 30 is pulled downward to lift the wire pulley 50, the hook 53 of the wire pulley 50 reaches above the existing communication cable.

[0026] The swivel structure 22 is provided at the tip of the main body 21 and includes a tubular portion 22a, a protruding portion 22b, and a pulley support portion 22c. The tubular portion 22a is, for example, cylindrical and has a diameter larger than that of the main body 21. The tubular portion 22a is provided so as to cover the tip of the main body 21 and is rotatable in the circumferential direction (around its axis). The protruding portion 22b is connected to the tubular portion 22a and is provided so as to protrude in the short side direction of the main body 21. The pulley support portion 22c is provided so as to extend downward from the tip of the protruding portion 22b. The pulley support portion 22c supports the pulley 23 so as to be rotatable in the circumferential direction (around its axis). The swivel structure 22 is formed of, for example, metal.

[0027] Pulley 23 is supported by pulley support portion 22c of swivel structure portion 22, and is rotatable in the circumferential direction of pulley support portion 22c, allowing its angle with respect to pulley support portion 22c to be adjusted. Pulley 23 has a groove in its roller portion, and rotates with operating rope 30 hung in said groove, thereby guiding and supporting operating rope 30 for movement. One end of operating rope 30 is operated by a worker on the ground via pulley 23, and the other end is connected to the tip of belt-shaped member 40. Operating rope 30 has a diameter of, for example, about 5 mm and a length of about 16 m, but is not limited to these, and may have a length that is strong enough to support wire pulley 50 and is at least twice the distance to the elevated attachment target.

[0028] <Configuration of Belt-Shaped Member 40> The structure of the belt-shaped member 40 according to this embodiment will be described below. Fig. 4 is a diagram showing the structure of the belt-shaped member 40 according to this embodiment.

[0029] As shown in FIG. 4, the belt-shaped member 40 includes a main body 41, a pulley holder 42, and a second rope support 43.

[0030] The main body 41 is a strip-shaped metal member, such as a flat bar. The tip of the main body 41 is connected to the other end of the operating rope 30 via the pulley 23 of the first rope support part 20, and the base end of the main body 41 is connected to the ring member 14 of the operating rod 10. Specifically, a pulley holder 42 is provided at the tip of the main body 41, and the tip of the pulley holder 42 is connected to the operating rope 30. A through hole is provided at the base end of the main body 41, and a ring member passing through the through hole is connected to the ring member 14 of the operating rod 10.

[0031] The pulley holder 42 is provided at the tip of the main body 41. The pulley holder 42 is a J-shaped metal hook capable of hooking the ring member of the pulley 50 shown in FIG. 5 . Specifically, the pulley holder 42 has a first portion extending in the planar direction of the main body 41 and a second portion bending from the base end of the first portion and moving away from the main body 41. The tip of the first portion of the pulley holder 42 and the main body 41 are connected, for example, by a screw, and the pulley holder 42 can rotate in the planar direction of the main body 41 around this connection point. At this time, the pulley holder 42 rotates while holding the pulley 50 so that its center of gravity is directly below the connection point. A through hole is provided in the first portion distal to the screw, and the other end of the operating rope 30 is passed through the through hole and tied to the pulley holder 42. The second portion of the pulley holder 42 may have a corrugated cross section with irregularities, for example, to prevent the pulley 50 from slipping off. The pulley holder 42 is hooked onto the ring member 56 of the pulley 50, and can lift the pulley 50 as the operating rope 30 moves.

[0032] FIG. 5 is a diagram showing a wire pulley 50 attached by the wire pulley attachment tool 1 of this embodiment.

[0033] As shown in Figure 5, the wire pulling pulley 50 includes a roller 51 that rotates relative to the towing rope and the newly installed communication cable, a support member 52 that rotatably supports the roller 51 at both ends, a hook 53 that is provided above the support member 52 and hooked onto the existing communication cable, an arm 55 that is rotatably supported at the base end of the hook 53 via a rotating shaft 54 ​​and opens and closes relative to the tip of the hook 53 as shown by the arrow in Figure 5, and a ring member 56 connected to the arm 55. When the ring member 56 is hung from the pulley holder 42, the tip of the arm 55 separates from the tip of the hook 53, and when the ring member 56 is removed from the pulley holder 42, the tip of the arm 55 returns to a state in which it is in contact with the tip of the hook 53.

[0034] As shown in FIG. 4 again, the second rope support part 43 is provided closer to the tip side than the longitudinal center of the main body 41, and movably supports one end of the operating rope 30. The second rope support part 43 is, for example, an eye bolt composed of a bolt part and a ring part. The bolt part of the eye bolt is connected to the main body 41, and the second rope support part 43 supports the operating rope 30 by passing one end of the operating rope 30 through the ring part. The operating rope 30 is operated via the second operating rope support part 43.

[0035] <How to install the wire extension car> A wire pulley wheel installation method using the wire pulley wheel installation tool 1 according to this embodiment will be described. Fig. 6 is a flowchart showing the wire pulley wheel installation method using the wire pulley wheel installation tool 1 according to this embodiment. Fig. 7 is a diagram showing the process of installing a wire pulley wheel 50 to an existing communication cable using the wire pulley wheel installation tool 1 according to this embodiment.

[0036] First, as shown in Figures 6 and 7, a towing rope for towing a new communication cable is set on the wire pulley 50 (step S11). The towing rope is connected to the new communication cable and is used to tow the new communication cable and place it on the rollers 51 of the wire pulley 50. The new communication cable is not placed on the wire pulley 50 from the beginning because the new communication cable is heavy, and if it were placed on the wire pulley 50, it would be difficult to lift the wire pulley 50.

[0037] Next, the pulley wheel mounting device 1 is attached to the existing communication cable (step S12). Specifically, the operating rod 10 of the pulley wheel mounting device 1 is lifted and the mounting portion 12 is hooked onto the existing communication cable. At this time, the pulley wheel 50 is not attached to the pulley wheel mounting device 1, so the worker can easily attach the pulley wheel mounting device 1 to the existing communication cable with ease. After the mounting portion 12 is hooked onto the existing communication cable, the worker releases the operating rod 10. As a result, the pulley wheel mounting device 1 is hung from the existing communication cable, and one end of the operating rope 30 and the belt-shaped member 40 connected to the other end of the operating rope 30 hang down via the pulley 23.

[0038] Next, on the ground, the pulley pulley 50 is set on the pulley holder 42 of the strip-shaped member 40 (step S13). Specifically, the strip-shaped member 40 on the other end of the operating rope 30 is pulled downward, lowering the position of the pulley holder 42. In this state, a worker on the ground hooks the ring member 56 of the pulley pulley 50 onto the pulley holder 42. With the ring member 56 hooked onto the pulley holder 42, the weight of the pulley pulley 50 causes the tip of the arm 55 to pivot upward relative to the tip of the hook 53, and the tip of the arm 55 moves away from the tip of the hook 53. This releases the hook 53, allowing the existing communication cable to be hooked onto it.

[0039] Next, one end of the operating rope 30 is pulled to lift the sheave 50, and the sheave 50 is attached to the existing communication cable (step S14). Specifically, by pulling one end of the operating rope 30 downward, the sheave 50 is lifted up to the existing communication cable together with the belt-shaped member 40. Then, by swinging the operating rope 30 left and right, the horizontal position of the sheave 50 is adjusted, and the hook 53 of the sheave 50 is hooked onto the existing communication cable. Thereafter, by releasing the tension on the one end of the operating rope 30, the ring member 56 of the sheave 50 is detached from the sheave holder 42. Then, the weight of the sheave 50 is released, and the tip of the arm 55 pivots downward relative to the tip of the hook 53, and the tip of the arm 55 comes into contact with the tip of the hook 53. This closes the hook 53, and the sheave 50 is stably held so as not to fall off the existing communication cable.

[0040] Next, the wire pulley wheel mounting device 1 is removed from the existing communication cable (step S15). If installation of all the wire pulley wheels 50 has not been completed (NO in step S16), the process returns to step S11 and the same work is carried out. On the other hand, if installation of all the wire pulley wheels 50 has been completed (YES in step S16), the wire pulley wheel installation work is completed. Thereafter, the new communication cable is connected to the towing rope, and in this state, the towing rope is pulled so as to be wound onto the drum.

[0041] <Summary> As described above, the wire pulley attachment device 1 in this embodiment includes the operating rod 10 that can be attached to an existing communication cable located at a high altitude, the first rope support part 20 connected to the tip of the operating rod 10, the operating rope 30 that is movably supported on the first rope support part 20 and operated by a worker on the ground, and the belt-shaped member 40 that is connected to the operating rope and can hold the wire pulley 50. As a result, after the operating rod 10 is attached to the existing communication cable, the wire pulley 50 can be attached to the existing communication cable by operating the operating rope 30. In other words, since there is no need to lift the wire pulley 50, which is a heavy object, when operating the operating rod 10, the wire pulley 50 can be easily and safely attached from the ground.

[0042] In this embodiment, the wire pulley 50 is held by a rigid band-shaped member 40 (flat bar), and the operating rope 30 is operated. This makes it possible to suppress excessive lateral movement and the range of movement of the wire pulley 50 when operating the operating rope 30, thereby improving operability. Furthermore, by connecting the ring member 14 of the operating rod 10 to the base end of the band-shaped member 40, the ring member 14 becomes movable along the operating rod 10, and the base end position of the band-shaped member 40 also moves while being guided along the operating rod 10. This makes it possible to further suppress the range of movement of the wire pulley 50, thereby further improving operability.

[0043] In this embodiment, a swivel structure 22 is provided on the first rope support 20. This allows the rotation angle of the belt-shaped member 40 and the pulley pulley 50 to be freely adjusted by operating the operating rope 30, making it easier to attach the pulley pulley 50 to the existing communication cable. Furthermore, the operating rope 30 is operated via a second operating rope support 43. By utilizing the moment of this second operating rope support 43, the angle provided by the swivel structure 22 can be easily adjusted.

[0044] In this embodiment, the pulley holder 42 can rotate in the planar direction of the belt-shaped member 40. This allows the pulley 50 to always hang downward due to its own weight, making it easy to hook the hook 53 of the pulley 50 onto the existing communication cable.

[0045] (Variation) FIG. 8 is a diagram showing a modified example of the first rope support part 20 of this embodiment. In the above embodiment, the tubular part 22a of the swivel structure part 22 is freely rotatable in the circumferential direction, but the present invention is not limited to this. As shown in FIG. 8, for example, the tubular part 22a may be rotatable in the circumferential direction and fixable at any angle. For example, the tubular part 22a may have a plurality of through holes 22d arranged in the circumferential direction, and may be fixed by fitting a button structure provided on the main body 21 inside the tubular part 22a into any of the through holes. The plurality of through holes 22d may be arranged at intervals of 30 degrees, for example.

[0046] In the above embodiment, the main body 11 of the operating rod 10 is formed from a single rod-shaped member, but the present invention is not limited to this. For example, the main body 11 may be configured to be extendable in the longitudinal direction, and a handle that can be held by the worker may be provided at the base end of the main body 11. This makes it easier to work according to the height of the existing communication cable or other object to which the pulley is to be attached, and further reduces the burden on the worker.

[0047] In the above embodiment, the traction rope is set in step S11 as the method for attaching the wire pulleys, but this is not limited to this. For example, the traction rope may be set after the installation of all the wire pulleys 50 is completed (after step S16). Also, in step S11, a new communication cable may be set from the beginning, instead of a traction rope.

[0048] In the above embodiment, the wire pulley 50 is attached to an existing communication cable, but the present invention is not limited to this. The object to which the wire pulley 50 is attached is not limited to an existing communication cable, and it may be attached, for example, to a utility pole or its attachment. The attachment to the utility pole may be, for example, a step bolt or overhead line fittings. Furthermore, if there is no existing communication cable between the utility poles, a temporary suspension wire may be temporarily erected between the utility poles, and the wire pulley 50 may be attached to this temporary suspension wire.

[0049] In the above embodiment, the object of the wire-extension work is an outdoor communication cable, but the present invention is not limited to this. For example, the object of the wire-extension work may be an electric wire, which is an example of a cable.

[0050] Although several embodiments of the present disclosure have been described above, these embodiments can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. These embodiments and modifications are intended to be included in the scope of the inventions and their equivalents as defined in the claims, as well as in the scope and spirit of the inventions.
