Description

  The present invention relates to a wire drawing auxiliary device and a wire drawing device.

  Conventionally, a wire-drawing operation for installing a linear body such as a rope (pilot rope) between two points has been performed. This wire drawing work may be performed in places that are difficult to move on foot, such as mountainous areas and valleys. In such places, flying objects such as kites and plastic bottle rockets are used for wire drawing work. For example, a flying object to which a linear body is attached is launched toward the opponent's point. The flying object that did not reach the opponent's point is fired again from that location toward the opponent's point. The linear body is extended to a point on the other party side by repeating the collection and launching of the flying object.

  In addition, a method using an unmanned helicopter as a flying object has been proposed (for example, see Patent Document 1). In this method, an unmanned helicopter makes a self-sustained flight to a point on the other party side using GPS (Global Positioning System), thereby performing the wire drawing work.

Hereinafter, the extension auxiliary device 20 and the extension device 1 according to an embodiment of the present invention will be described with reference to FIGS.
First, the wire drawing work will be described.

  The wire drawing operation is an operation of arranging a linear body such as a cable, a wire, or a rope between at least two points. In the wire drawing work, for example, a pilot rope for constructing an electric wire (a rope serving as a scaffold for constructing the electric wire) is disposed between at least two points. In the wire drawing work, the linear body is arranged by moving one end of the pilot rope from one of at least two points toward the other point. By this wire drawing work, a pilot rope is arranged between at least two points. The pilot rope is installed between a structure at one point (a steel tower, a power pole, a pier, a bucket car, etc.) and a structure at a other point (a steel tower, a power pole, a pier, a bucket car, etc.).

  The wire drawing device 1 according to the present embodiment is used for wire drawing work. For example, the wire drawing device 1 is used for wire drawing work in places where it is difficult to wire by foot such as mountains and valleys. The wire-drawing device 1 extends between at least two points by flying over at least two points.

As shown in FIG. 1, the wire drawing device 1 conveys the tip of a linear body such as a pilot rope from at least one point (first point A) to the other point (second point B), The wire is drawn. Specifically, the wire drawing device 1 extends the linear body by moving the tip of the linear body to the second point B while pulling the linear body from the reel 100 arranged at the first point A. To line. The wire drawing device 1 includes a flying object 10 and a wire drawing auxiliary device 20.
In the present embodiment, the linear body drawn out from the reel 100 and transported is described as the “second linear body 200”. In the present embodiment, a ring 200 </ b> C is formed at the tip of the second linear body 200 as shown in FIG. 2. Specifically, the tip of the second linear body 200 is folded back and tied to the midway portion, thereby forming the ring 200C.

  The flying object 10 is a drone (multi-rotor helicopter) that can be autonomously controlled by, for example, a GNSS (Global Navigation Satellite System), a barometer, an infrared sensor, a camera sensor, a sound wave sensor, or the like. The flying object 10 includes a casing 11 in which various sensors and the like are arranged, and a rotary wing 12 attached to the casing 11. In the present embodiment, four rotating blades 12 are arranged on the upper portion of the casing 11 with the axial direction facing upward from the casing 11.

  The extension assisting device 20 is a mechanism that connects the housing 11 and the linear body (second linear body 200). The extension assisting device 20 extends from the housing 11. The extension assisting device 20 includes a guide 21, a first linear body 22, a weight 23, and a separation unit 24.

  The guide 21 is a rod and is provided integrally with the housing 11. In the present embodiment, the guide 21 is attached to the lower end portion of the housing 11 using an attachment mechanism (not shown). One end portion (tip portion) of the guide 21 extends beyond the rotary blade 12. The guide 21 is attached so that the extending direction (axial direction) extends in a direction different from the direction toward the rotary blade 12. That is, the guide 21 is attached so that the extension line of the shaft and the rotor blade 12 do not overlap. In the present embodiment, the guide 21 extends from the rotating blade 12 along the extending direction of a blade (not shown) of the rotating blade 12.

  The first linear body 22 is, for example, a rope. One end of the first linear body 22 is fixed to the distal end portion of the guide 21 in the extending direction. Then, the first linear body 22 is suspended from the distal end portion of the guide 21 in the extending direction. In the present embodiment, a ring 22 </ b> C is formed at the tip of the first linear body 22 that is suspended. Specifically, the suspended tip of the first linear body is folded back and tied to the midway portion, thereby forming the ring 22C.

  The weight 23 is attached to the suspended tip of the first linear body 22. Specifically, the weight 23 is attached to the proximal end side from the ring 22 </ b> C at the distal end portion of the first linear body 22. As a result, the weight 23 maintains the first linear body 22 suspended from the front end of the guide 21 in the extending direction.

  The separation part 24 is made of metal, and is, for example, an eyeball clip or a double clip-shaped clamping body. The separation part 24 is disposed on the distal end side of the weight 23 in the first linear body 22. The separation unit 24 is configured to be able to connect a second linear body 200 different from the first linear body 22 to the first linear body 22. In the present embodiment, the separation unit 24 connects the second linear body 200 drawn from the reel 100 to the first linear body 22. The separation unit 24 includes a clamping unit 241 and a connection unit 242.

  The clamping part 241 clamps either one of the front-end | tip parts of the 1st linear body 22 and the 2nd linear body 200 so that attachment or detachment is possible. In this embodiment, the clamping part 241 clamps the front-end | tip part of the 2nd linear body 200 so that attachment or detachment is possible. The clamping part 241 has a shape in which the plate-like body is folded back into a concave shape. And the both ends by which the clamping part 241 was turned on mutually contact and press the other party.

  The connecting portion 242 protrudes from each of the outer surfaces at the two folding positions of the holding portion 241. The connecting part 242 connects the other of the first linear body 22 and the second linear body 200 to the sandwiching part 241. Specifically, in the present embodiment, the connecting portion 242 connects the first linear body 22 to the sandwiching portion 241. The connecting part 242 has an insertion part 243 through which the other of the first linear body 22 and the second linear body 200 can be inserted. In the present embodiment, the insertion part 243 inserts the first linear body 22. Specifically, the insertion part 243 inserts the first linear body 22 so that a part thereof is disposed inside the ring 22 </ b> C at the tip of the first linear body 22.

Next, wire drawing work using the wire drawing device 1 will be described.
As shown in FIG. 3, the wire drawing work is described using an example in which the second linear body 200 is extended from a first point A at the summit to a second point B at the foot of the mountain. Specifically, the wire drawing work is described as an example in which the second linear body 200 is extended from the utility pole at the first point A to the utility pole at the second point B having a lower altitude.

  First, the flying object 10 is positioned at the first point A. Here, the clamping part 241 clamps the tip of the second linear body 200 drawn out from the reel 100 as shown in FIG.

  Next, the flying object 10 takes off from the first point A toward the second point B as shown in FIG. The weight 23 hangs down the first linear body 22. The flying object 10 flies while lowering the altitude from the first point A having a high altitude to the second point B having a low altitude. As the flying object 10 flies while lowering the altitude, a rising air flow is relatively generated in the flying object 10. In contrast, the weight 23 maintains the first linear body 22 in a suspended state. Thereby, the flying body 10 flies from the first point A to the second point B in a state where the first linear body 22 and the second linear body 200 are suspended from the flying body 10. As shown in FIG. 5, the flying body 10 pulls the second linear body 200 from the reel 100 to the second point B. The second linear body 200 can be installed between the first point A and the second point B by being separated from the flying body 10 by the worker waiting at the second point B. . Even when the second linear body 200 is separated from the flying body 10, the weight 23 maintains the first linear body 22 in a state where it is suspended from the flying body 10. Then, as shown in FIG. 6, the separated wire is attached to the utility pole at the second point B, and the wire drawing work is completed.

  By the way, when the 2nd linear body 200 is caught in the obstacle T (for example, tree etc.) in the middle of the flight of the flying body 10, the 2nd linear body 200 cannot extend any more. Therefore, a large tension is generated in the first linear body 22 and the second linear body 200 due to the force generated due to the flying body 10 moving in the flight direction (second point B). As illustrated in FIG. 7, the separation unit 24 separates the second linear body 200 from the first linear body 22 using a force that pulls the first linear body 22 in the flight direction of the flying body 10. Specifically, the clamping unit 241 releases the clamping of the second linear body 200 by using a force that pulls the first linear body 22 in the flight direction of the flying body 10. Accordingly, the separation unit 24 separates the second linear body 200 from the first linear body 22. When the second linear body 200 is separated from the first linear body 22, the first linear body 22 is maintained in a state where it is suspended by the weight 23.

According to the above-mentioned extension auxiliary device 20, the following effects are produced.
(1) The extension assisting device 20 is a rod-shaped guide 21 that is mounted on the casing 11 of the flying object 10 and has a tip extending beyond the rotating blade 12, and the extending direction is directed to the rotating blade 12. A guide 21 that is mounted in a different direction, a first linear body 22 that is suspended from the distal end portion in the extending direction of the guide 21, and a weight 23 that is attached to the distal end portion of the first linear body 22 that is suspended. The first linear body 22 is disposed on the tip side of the weight 23, and a second linear body 200 different from the first linear body 22 can be connected to the first linear body 22, and the first And a separation unit 24 that can separate the second linear body 200 from the linear body 22. Even if the second linear body 200 is separated from the first linear body 22 by attaching the weight 23 to the tip of the first linear body 22, the weight 23 is removed from the first linear body 22. Does not fall off. Thereby, regardless of the separation of the second linear body 200, the load applied to the flying object 10 does not change greatly, so that the balance of the flying object 10 is maintained. Therefore, the safety of wire drawing work can be improved.

  In addition, when the wire is extended from the first point A to the second point B, the first linear body 22 is attached to the tip of the guide 21 and moves while being suspended by the weight 23. In particular, even when the flying object 10 descends from the first point A, which is higher than the second point B, toward the second point B, and a wind that winds up the first linear body 22 occurs, The one linear body 22 is separated from the rotary blade 12 by the guide 21 and is suspended by the weight 23. Thereby, since it can suppress that the 1st linear body 22 is caught in the rotary blade 12, the safety | security of wire drawing work can be improved.

(2) The separation unit 24 separates the second linear body 200 from the first linear body 22 against a predetermined tension or more acting on the second linear body 200 and the first linear body 22. . Thereby, even when the second linear body 200 is caught by the obstacle T, the second linear body 200 can be separated from the first linear body 22. Therefore, since it is possible to suppress an abnormal force from the first linear body 22 acting on the flying body 10, the safety of the wire drawing work can be further improved.

(3) The separation part 24 is sandwiched between the first linear body 22 and the second linear body 200 so as to be detachably sandwiched between the first linear body 22 and the second linear body. And a connecting portion 242 that connects the other side of the body 200 to the sandwiching portion 241. Thereby, even if an abnormal tension is generated in the second linear body 200, one of the first linear body 22 and the second linear body 200 can be released from the clamping, so that the flying object 10 On the other hand, the application of abnormal tension can be suppressed. Thereby, the safety | security of wire drawing work can be improved. Moreover, since the separation part 24 can be simply configured, the cost of configuring the wire drawing auxiliary device 20 can be suppressed.

(4) The connection part 242 is configured to include an insertion part through which the other of the first linear body 22 and the second linear body 200 can be inserted. Thereby, the connection part 242 can hold | maintain the other of the 1st linear body 22 and the 2nd linear body 200 which were penetrated by the insertion part 243, and the wire extension auxiliary | assistance apparatus 20 can be comprised easily.

  As mentioned above, although one preferred embodiment of the wire drawing auxiliary device of the present invention was described, the present invention is not limited to the above-described embodiment, and can be modified as appropriate.

  For example, in the above embodiment, the linear body is a cable, a wire, a rope, or the like, but is not limited thereto. Moreover, a linear body may be installed between the 1st point A and the 2nd point B whose at least one is the ground.

  Moreover, in the said embodiment, although the guide 21 was demonstrated as a structure different from the housing | casing 11 of the flying body 10, it is not restrict | limited to this. The guide 21 may be integrated with the casing 11 of the flying object 10. That is, the guide 21 may be configured as one configuration of the housing 11.

  Moreover, in the said embodiment, although the clamping part 241 clamped the 2nd linear body 200, it is not restrict | limited to this. Moreover, although the connection part 242 hold | maintained the 1st linear body 22, it is not restrict | limited to this. The clamping unit 241 may clamp the first linear body 22. At this time, the connecting portion 242 may hold the second linear body 200.

  In the above-described embodiment, the clamping unit 241 is set with a tension (load) for releasing the clamping with respect to a tension (load) applied to the other of the first linear body 22 and the second linear body 200 to be sandwiched. May be. The clamping unit 241 includes a pressure and physical properties for clamping the other of the first linear body 22 and the second linear body 200, and a clamping method of the second linear body 200 (for example, the first linear body 22 and the second line The tension for releasing the clamping may be set by at least one of the other two of the shape bodies 200 being clamped together.

  Moreover, in the said embodiment, although the clamping part 241 clamped the other of the 1st linear body 22 and the 2nd linear body 200, it is not restrict | limited to this. For example, both ends of the sandwiching portion 241 that contact each other may be positioned inside the ring at the other end of the first linear body 22 and the second linear body 200 that are annular. That is, you may make it the both ends of the clamping part 241 hook the other ring of the 1st linear body 22 and the 2nd linear body to a contact position. Such a form is also included in the clamping by the clamping unit 241.
