Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for extending a rope between steel towers using an unmanned helicopter.

[0002]

2. Description of the Related Art Conventionally, a method as shown in FIG. 7 has been employed as a method for extending a rope between steel towers, for example, in the construction of a tower electric wire. FIG. 7 shows a rope 3 from one tower 1 to the other tower 2.
It shows how to extend the line, and unmanned helicopter 4
The rope 3 is wound around a drum 5 provided in the vehicle, and the rope 3 is pulled out from the drum 5 by causing the unmanned helicopter 4 to fly forward with the tip 3a of the rope 3 fixed to one of the steel towers 1. Then, the unmanned helicopter 4 is caused to fly to the other tower 2, and the rope 3 is fixed to the other tower 2.

[0003]

However, when the rope 3 is extended as described above, if the electric wire 6 crosses between the two towers 1 and 2, the rope 3 hangs down due to the weight of the rope 3. May come into contact with the electric wire 6.

[0004] Therefore, an object of the present invention is to provide a rope extending method capable of extending a rope without interfering with an obstacle such as an electric wire.

[0005]

In order to achieve the above object, according to the first aspect of the present invention, a tip of a rope wound around a drum of a first unmanned helicopter is fixed at a predetermined position. In a method of pulling out a rope wound around a drum of the first unmanned helicopter by flying the first unmanned helicopter, extending an obstacle between the predetermined position and the first unmanned helicopter. Hovering a second unmanned helicopter over the sky, and suspending the rope by suspending means provided on the second unmanned helicopter so that the rope does not interfere with the obstacle when the rope is extended. It is characterized by using a rope extension method using an unmanned helicopter.

According to a second aspect of the present invention, there is provided the suspension unit according to the first aspect, wherein the ring into which the rope is loosely inserted is provided so as to be openable and closable, and the ring is opened and closed via a driving unit by radio control. An unmanned helicopter is configured such that the rope is inserted into the ring and suspended when closed, and the rope is opened when opened.

[0007]

Embodiments of the present invention will be described below.

FIGS. 1 to 6 show an embodiment of the present invention.

In this rope extending method, a first unmanned helicopter 4 and a second unmanned helicopter 8 are used.

The first unmanned helicopter 4 is provided with a drum 5 as shown in FIG. The drum 5 is rotatably disposed on a support member 9 fixed to the lower surface of the unmanned helicopter 4, and the rope 3 is wound around the drum 5. The rope 3 is inserted into a hole 10 a formed in the portal member 10.

As shown in FIG. 6, a ring 11 which can be freely opened and closed is provided on the lower part of the second unmanned helicopter 8. The ring 11 is divided into an upper ring portion 11a and a lower ring portion 11b, and the upper ring portion 11a is fixed to a lower surface portion of the second unmanned helicopter 8 via a bracket 12. This upper ring portion 11a has a shaft 1
The lower ring portion 11b is rotatably connected via 1c, and by rotating the lower ring portion 11b,
The ring 11 is opened and closed. A protrusion 11d is formed on the lower ring portion 11b.
The lower end of an up-and-down lever 13 is connected by a shaft 14. When the up / down lever 13 is moved up and down by a signal from the control transmitter, it is closed as shown in FIG. 6A or opened as shown in FIG. 6B. .

Next, a method of extending a rope 3 between the towers 1 and 2 using the unmanned helicopters 4 and 8 will be described.

First, the rope 3 extended from the drum 5 of the first unmanned helicopter 4 is inserted into the closed ring 11 of the second unmanned helicopter 8, and the tip 3a of the rope 3 is connected to one end. It is fixed to the tower 1. In this state, the first unmanned helicopter 4 is made to fly forward and the second unmanned helicopter 8 is made to fly forward (see FIG. 1).

Then, as shown in FIG. 2, the second unmanned helicopter 8 is hovered in a state where the second helicopter 8 has reached the sky above the electric wire 6, while the first helicopter 4 is caused to fly forward as it is. . Then, as shown in FIG. 3, the first unmanned helicopter 4 is
The rope 3 is pulled through the upper part and fixed to the tower 2.

Thereafter, as shown in FIG. 4, the up / down lever 13 is raised by the control signal to lower the lower ring portion 11b.
Is rotated downward to open the ring 11 and release the rope 3.

Since the rope 3 is laid between the steel towers 1 and 2 in this way, even if the electric wire 6 crosses the way, the rope 3 is hung by the second helicopter 8 while the rope 3 is suspended. The rope 3 does not interfere with the electric wire 6 because the cable 3 is bridged.

In the above embodiment, an openable and closable ring is used as the suspending means. However, the present invention is not limited to this, and other mechanisms may be used as long as the rope can be suspended or opened. . In the above embodiment,
Regarding the extension method of hanging rope 3 between towers 1 and 2,
Although the present invention has been applied, it is needless to say that this method can also be applied to a case where the object is bridged between other objects.

According to the invention described in claim 1 or 2,
Even if there is an obstacle such as an electric wire in the middle of both positions where the rope is to be hung, while hovering the second unmanned helicopter over this sky and suspending the rope,
Since the first unmanned helicopter is made to fly forward, the rope does not interfere with the obstacle, and the rope or the obstacle can be prevented from being damaged.
