[Industrial applications]

 The present invention relates to an airborne machine used for repairing a power line installed at a high place.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 5, a rotating body 42 that moves in a state where its lower portion is locked to a power transmission line 41 installed at a high place is arranged at a predetermined interval, and both rotating bodies 42 are An aerial vehicle is provided in which a supporting rod 43 is hung on a rotating shaft and a stool 44 on which a worker sits is erected between the lower portions of the supporting rod 43. Reference numeral 46 is a gripping rod.

A ring member 45 for preventing snow accretion is fitted on this type of power transmission line 41 at a predetermined interval, and this ring member 45 causes snow to accompany the power transmission line 41 and the amount of snow accretion. When the snowfall reaches a certain level, the snowfall is divided, and the ring member 45 rotates with respect to the power transmission line 41 to drop the snowfall on the power transmission line 41. Therefore, the ring member 45 is an epoch-making one and indispensable for preventing snow from accumulating on the power transmission line 41.

[0004]

[Problems to be solved by the device]

 By the way, when a worker rides on an airborne vehicle to repair or repair the power transmission line 41 or replace the ring member 45, the power transmission to the power transmission line 41 is naturally stopped. To be done. However, in general, a plurality of power transmission lines are often installed in parallel, in which case the airborne vehicle is charged due to the influence of the surrounding power transmission lines (not shown).

On the other hand, the rotating body 42 and the gripping rod 46, etc., which is installed between these rotating bodies 42 and is gripped by the operator, are usually made of metal, but the portion of the rotating body 42 that abuts the power transmission line 41. Since the cushioning rubber is wound around, the spacecraft and the power transmission line 41 are well insulated.

For this reason, a large amount of static electricity is accumulated in the U-ride machine, and a large amount of static electricity is also accumulated in the operator riding on the air-borne machine. The static electricity causes discharge to the power transmission line 41 at the moment when the worker tries to touch the power transmission line 41, causing a tingling sensation or numbness (discharge phenomenon). Such a discharge phenomenon not only hinders the movement and work of the worker on the power transmission line 41, but is also dangerous. Especially when the worker gets wet with rain or sweat, the electricity is strongly felt and the working ability is significantly reduced.

In order to solve such a problem, conventionally, one end of a metal wire rod is fixedly attached to a gripping rod 46 of an air vehicle, and the other end is formed into a ring shape having a diameter substantially equal to that of the power transmission line 41. Then, the earthing method was adopted by loosely fitting it to the power transmission line 41, but in this method, the ring portion of the metal wire is caught by the ring member 45 for preventing snow accretion, which hinders the movement of the air vehicle. However, there was a drawback that the work became difficult.

The present invention solves such a problem, and it is technically possible to provide an airborne machine capable of discharging static electricity accumulated in a worker without hindering the work of the worker. This is an issue.

[0009]

[Means for Solving the Problems]

 The gist of the present invention will be described with reference to the accompanying drawings.

The left and right rotating bodies 2 a and 2 b (2 is used as a pair of pulleys. The same applies to other members) which move in a state where the lower part is locked to the power transmission line 1 installed at a high place. The support rods 4a, 4b are vertically arranged on the rotary rods 2a, 2b so as not to interfere with the rotation of the rotary rods 2a, 2b. 4b, in which a worker sits on a stool plate 5, an electrically conductive rod body 6 is pivotally attached to the air bearing machine, and the electrically conductive rod body 6 is engaged with the electrically conductive rod body. The present invention relates to an airborne vehicle characterized in that it is provided with a conductive rotating body 7 that comes into contact with the power transmission line 1.

[0011]

[Action]

 Even if electricity is accumulated in the airborne vehicle and the worker riding on the airborne vehicle, this electricity is discharged (grounded) to the power transmission line 1 through the conductive rod body 6 and the conductive rotating body 7, and the worker is It is not bothered by charging. At this time, the conductive rotating body 7 abutting on the conductive rod body 6 is rotated, and the conductive rod body 6 to which the conductive rotating body 7 is attached is pivotally attached to the support rod 4, so that it is in the air. Even if the passenger moves on the power transmission line 1, the passenger can easily move over the power transmission line 1 without getting caught on the ring member 10 and getting over them.

[0012]

【Example】

 1, 2, 3 and 4 show an embodiment of the present invention. FIGS. 1 and 2 show a first embodiment, FIG. 3 shows a second embodiment, and FIG. 4 shows a third embodiment. It was done. This will be described below.

As shown in FIGS. 1 and 2, in the air vehicle according to the embodiment, a pulley 2a, which serves as a rotating body that rotates while a lower portion is locked to a power transmission line 1 installed at a high place, 2b are attached to both ends of the metal gripping rod 8, and metal supporting rods 4a and 4b are vertically provided on the pulleys 2a and 2b via metal frame members 9a and 9b, respectively. A wooden stool 5 on which a worker sits is installed between the lower parts of 4a and 4b. In addition, a metal plate-shaped conductive rod body 6 is pivotally supported on both sides of the pulley 2a (or may be one side) by a spindle 3a on the spindle 3a of the pulley 2a on the right side in FIG. (The drawing shows the conductive rod 6 on the outside of the frame 9a.) At the tip of the conductive rod 6, a metal roller 7 (conductive rotating body 7 in the claim) is pivotally attached. Has been done. The roller 7 preferably has a certain thickness so as not to fall off the power transmission line 1. Reference numeral 14 is a locking hook, 15 is a locking ring, and 16 is a brake mechanism.

Since the airborne vehicle according to the embodiment has the above-described configuration, the following operational effects are exhibited.

The airborne vehicle is set on the power transmission line 1. That is, the conductive rod body 6 is manually lifted and slid upward, and the pulleys 2a and 2b are locked to the power transmission line 1 while the locking ring 15 is locked to the locking hook 14, and the locking hook 14 and The engagement with the engagement ring 15 is released, and the roller 7 is brought into contact with the power transmission line 1. When an operator rides on the airborne machine in this state and performs a predetermined work, the conductive rod body 6 and the roller 7 are conductive and the lower surface of the roller 7 is always in contact with the power transmission line 1. Even if electricity is accumulated on the rider and the worker 11 who is on this airborne vehicle, this electricity is discharged to the power transmission line 1 through the conductive rod body 6 and the roller 7, so that the worker 11 is charged with this electricity. Will not bother you. Further, since the conductive rod body 6 is pivotally attached to the frame body 9a and the roller 7 is rotatable with respect to the conductive rod body 6, the snow transmission prevention ring member 10 is fitted to the power transmission line 1. However, the rollers 7 can easily get over them without being caught by the ring members 10 and can easily rotate on the power transmission line 1 without lowering the working capacity.

Further, with the above configuration, the conventional product can be easily changed to the present embodiment only by the work of pivotally supporting the conductive rod body 6 on the pulley 2a using bolts or the like, which is extremely Product price will increase.

FIG. 3 shows a second embodiment, in which another metal conductive rod 12 is pivotally attached to the tip of the conductive rod 6 shown in the first embodiment, and the end of the conductive rod 12 is connected. Roller made of metal 1
3 is pivotally supported.

According to the airborne vehicle of this embodiment, the resin-made ring members 10 fitted to the power transmission line 1 are non-conductors, and the roller 7 or the roller 13 is attached to the ring members 10.
Even if the vehicle is in a riding state, both rollers 7 and 13 will not ride on the two ring members 10 at the same time unless the distance between the rollers 7 and 13 is the same as the attachment interval of the ring member 10. One of the rollers comes into direct contact with the power transmission line 1, and the electricity accumulated in the airborne vehicle and the worker 11 is surely discharged to the power transmission line 1. The other operational effects are similar to those of the first embodiment.

FIG. 4 is a third embodiment, and relates to the second embodiment of an air vehicle of the type in which a brake mechanism 17 for stopping the rotation of the pulley 2a is arranged in addition to the brake mechanism 16. The rollers 7 and 13 are provided. The operational effects of the airborne vehicle according to the third embodiment are similar to those of the airborne vehicle according to the second embodiment.

[0020]

[Effect of the device]

 Since the present invention is configured as described above, the conductive rotating body can easily get over the ring member fitted to the power transmission line and abut on the cable while easily getting over them. Electricity accumulated in the operator on board the machine is discharged to the power transmission line through the conductive rotating body, so that the operator is not annoyed by electrification, which is an excellent effect.
