DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of extending a wire by using a remote control flying vehicle, which is used for construction of an overhead line.

[0002]

2. Description of the Related Art When laying a power transmission line between towers, a thin pilot rope (eg, fishing line) made of nylon is first extended, then a rope is connected to the end of the pilot rope, and the rope is further wired. Connect the transmission line to the cable and pull it to finally build the transmission line. As one of the methods for extending the pilot rope, there is known a method in which a pilot rope is erected between steel towers using a radio-controlled model helicopter.

[0003]

In the conventional method, the helicopter was operated by one person. Therefore, when the visibility of the pilot deteriorates, for example, when there is an obstacle between the takeoff point and the landing point of the helicopter, it is necessary to climb the tower and perform the radio operation. Therefore, the conventional method is a dangerous operation, and the operation efficiency is poor. The present invention has been made in view of this point, and it is an object of the present invention to provide a safe and efficient method of extending a wire using a remote control flying vehicle.

[0004]

According to the present invention, there is provided a method for extending a line by a remote control vehicle equipped with a pilot rope, the method comprising: switching wireless operation of the remote control vehicle from a plurality of points. To steer.

[0005]

FIG. 1 is a schematic diagram for explaining an embodiment of a wire drawing method according to the present invention. Now, when the line is extended from the tower X to the tower Y, according to the conventional method, the field of view of the pilot A is the obstacle Z.
The pilot A had to climb the tower X and operate the helicopter H because it was interrupted by the tower and could not see the tower Y. In this embodiment, the pilot B is arranged near the tower Y, and the pilots A and B control the helicopter H by switching the wireless operation by two people. That is, the pilot A drives from the tower X to the switching point S, switches the control at the point S, and thereafter the pilot B drives to the tower Y. As the S point, a position at which both the pilots A and B can view the helicopter H is selected. According to the above-described method, even if there is an obstacle between the towers and visibility is poor, it is not necessary to climb the tower, and a safe and efficient wire drawing operation can be performed.

FIG. 2 is a side view of a reel 1 around which a pilot rope P is wound and a gantry 3 for mounting the reel 1, FIG. 3 is a front view thereof, and FIG. 4 is a plan view thereof. The winding shaft of the reel 1 is supported by a U-shaped bracket 5, and a mounting shaft 7 is provided on the bracket 5, and a through hole is formed at the upper end of the mounting shaft 7.

The gantry 3 is made of aluminum steel and has four legs 3
1, 32, 33 and 34 are provided. The mount 3 is provided with a mounting plate 35 for mounting the reel 1. The mounting plate 35 is formed with a mounting hole through which the mounting shaft 7 passes, and further provided with a pin 9 inserted into a through hole of the mounting shaft 7. The reel 1 is mounted on the gantry 3 by passing the mounting shaft 7 through the mounting hole and fixing it with the pin 9. At this time, the reel 1 is rotatable around the mounting shaft 7, so that the direction of the reel 1 changes according to the flight direction of the recopter H, and the pilot rope P is smoothly pulled out.

[0008] The pin 9 is actuated by an actuator 11. The actuator 11 may be any actuator as long as the pin 9 can be inserted into and removed from the through-hole. For example, a servomotor and a crank mechanism can be used to change the rotational motion of the motor into a linear motion of the pin 9. Instead, a rack and pinion, a cam mechanism, or the like may be used.

A bifurcated wire 13 is provided at both ends of the winding shaft of the reel 1.
Each end of the wire rod 13 is fixed.
Is attached. The pilot rope 9 is pulled out through the guide tube 15. By guiding with the guide tube 15, the pilot rope 9 can be prevented from being caught in the body of the helicopter H or the gantry 3.
In addition, if the wire 13 and the pipe 15 are used as described above, it is possible to guide the pilot rope with an extremely simple and inexpensive configuration and reliably.

FIG. 5 is a block diagram showing a circuit configuration of a remote controller for operating the helicopter H. Although the pilots A and B use the same device, they are distinguished from each other by adding suffixes a and b to the reference numbers in FIG. Remote control device 20 includes the following components. That is, the receiver 2 for communicating with the other remote control device
1, a main transmitter 22 for transmitting to a receiver 30 of a helicopter H, a switching transmitter 2 for transmitting a steering switching signal
3, a control circuit 24 for controlling each transceiver, a changeover switch 25 for changeover operation, a group of operation switches 26 for various operations of the helicopter H, and an antenna 27. Although not shown, the remote control device 20 may be provided with a display device (such as an LCD) for displaying a remote control switching operation and a helicopter operation state, which will be described later.

Next, an actual wire drawing operation using the above device will be described. First, the helicopter H mount 3
Attach reel 1 to As described above, the mounting shaft 7 is inserted into the mounting hole of the mounting plate 35 and stopped with the pin 9. The helicopter H is started from the vicinity of the tower X by the pilot A, and thereafter, the pilot A operates the helicopter H by operating the operation switch group 26a of the remote control device 20a until the switching point S is reached. At this time, the pilot may be operated while communicating with the pilot B using another wireless device.

When the helicopter H reaches the switching point S, the pilot B presses the switch 25b. At this time, the main transmitter 22b of the remote control device 20b has not been activated yet. In response to the signal from the changeover switch 25b, the control circuit 24b switches the changeover transmitter 23b (frequency is set to the main transmitter 2).
2b) to output a switching signal. When this switching signal is received by the receiver 21a of the remote controller A, the control circuit 24a stops supplying power to the high-frequency circuit of the main transmitter 22a of the remote controller A and prohibits the operation by the remote controller A. On the other hand, the control circuit 24a includes a switching transmitter 23a.
To send a switching signal to the remote controller 20b. When the receiver 21a of the remote controller 20b receives the switching signal, the control circuit 24b activates the main transmitter 22b.
After that, the pilot B performs the radio control by the operation switch group 26b.

A switching signal for steering switching can be transmitted from the remote controller 20a by the pilot A. In this case, the reverse operation is performed. That is, when the changeover switch 25a of the remote control device 20a is pressed, the control circuit 24
A activates the switching transmitter 23a to output a switching signal. When this switching signal is received by the receiver 21b of the remote controller B, the control circuit 24b sends the signal to the main transmitter 22 of the remote controller B.
The power supply to the high-frequency circuit b is started to allow the remote control device B to operate. On the other hand, the control circuit 24b operates the switching transmitter 23b to send the switching signal to the remote control device 20a.
When the receiver 21a of the remote controller 20a receives the switching signal, the control circuit 24a stops supplying power to the high-frequency circuit of the main transmitter 22a.

When the helicopter H arrives at the tower Y, the reel 1 is separated. First, the remote control device 20
When a disconnection switch (not shown) in the operation switch group 26b is operated, a reel disconnection signal is transmitted from the main transmitter 22b, and when the receiver 30 of the helicopter H receives the signal, the actuator 11 is activated. , The pin 9 is pulled out from the mounting shaft 7. Therefore, the reel 1 falls by its own weight, and the extension of the pilot rope ends.

According to the above-described method, a safe and efficient wire drawing operation can be performed. Further, a switching signal is transmitted at the time of steering switching so that the switching can be automatically performed, so that the switching operation is reliable and easy. In addition, since the winding reel of the pilot rope is dropped when the helicopter reaches the destination, the effect that the extension work can be greatly facilitated is obtained.

Finally, the present invention is not limited to the above embodiment, and various modifications and applications are possible. For example,
The remote control flying object is not limited to a helicopter, and other flying means such as an airship can be used. Further, in the above embodiment, the radio control was performed by two pilots. However, the present invention is not limited to the two pilots, and more pilots may be arranged according to the topography of the installation location of the transmission line to perform radio control. It may be.
