Description

[Detailed Description of the Invention] The present invention relates to a self-propelled aircraft that propels itself through the air using electric wires or ropes. In more detail, it is a self-propelled machine that can safely pass through obstacles such as insulators and fasteners that fix electric wires and ropes, and obstacles such as wire stopper metal fittings and branch lines. This relates to a self-propelled aircraft suitable for

Generally, in high-voltage power line replacement work, shortening power outage time is important for ensuring a stable supply of electricity. Conventionally, in these construction works, a wire extension rope is first extended along the existing wire, then a new wire is connected to the wire extension rope and the wire extension rope is pulled to extend the new wire, and then the new wire is extended along the existing wire. We tried to shorten the power outage time as much as possible by using the replacement construction method. Therefore, the existing wires will remain energized and live until they are replaced with new wires. When passing the wire extension rope in this way, the existing electric wire is a live wire, and the work of passing the wire extension rope is often done manually by workers, which is not only dangerous but also inefficient. In order to speed up work, conventionally, self-propelled machines have been seen that run on aerial wires, but these self-propelled machines do not have to deal with obstacles such as aerially connected branch lines or insulators that secure the wires. I couldn't get through it at all. Therefore, in order to pass these obstacles, workers must rely on their hands, and as workers have to climb up each utility pole, there is a risk of electric shock, and there is little hope of improving work efficiency. Ta.

On the other hand, conventional means for transporting items in the air include lifts, air shooters, conveyors,
There were hoists, etc., but these require a large installation space and are complicated to rearrange the installation.
It is expensive and uses installed guides, rails, etc. to control the goods and transport them to the destination, and like a self-propelled machine, it selectively determines the direction and travels to the desired destination. It was not possible to transport goods.

In addition, recently, self-propelled transport systems using guide rails and trolleys have been seen, but these require large-scale construction work and installation space when installed in existing buildings, and are extremely expensive. It was hot.

As described above, until now, there has been no self-propelled machine capable of freely transporting goods and the like to any desired destination by moving itself through the air simply by extending electric wires or ropes.

Furthermore, self-propelling in the air by connecting multiple electric wires or ropes is preferable in terms of self-propelling stability, but when replacing electric wires, as mentioned above, the line voltage is high due to the live wires. As a result, there is a risk of electrical leakage or short circuits, and when transporting goods, the wiring of electric wires and ropes becomes complicated and costs increase.

As mentioned above, a self-propelled vehicle that can self-propel in the air by connecting a single electric wire or rope, can selectively self-propel to any destination, and can stably pass through obstacles such as insulators and fasteners. The plane was nowhere to be found. Moreover, a low-cost self-propelled machine that does not require a complicated control mechanism, can be made lightweight and compact, and has a wide range of uses has not yet been found.

The purpose of the present invention is to provide a self-propelled machine that eliminates the problems of conventional self-propelled machines as described above, and that can safely and efficiently save labor in replacing electric wires in a short time. Another object of the present invention is to provide a self-propelled machine that enables a transport system that can be installed easily at a lower cost than conventional transport systems. Furthermore, it is an object of the present invention to provide a low-cost self-propelled machine that does not require a complicated control mechanism, is light and compact, is easy to handle, and has a wide range of uses.

Next, an embodiment of the present invention will be described based on the drawings.

Figure 1 shows a self-propelled machine according to an embodiment of the present invention;
3 and 4 are partial views of the self-propelled machine of FIG. 1.

The frame 1 includes driving wheels 2a, 2b and a guide 4.
a, 4a', 4b, 4b' and ballast cars 7, 7'
is installed.

The drive wheels 2a, 2b are attached to the frame 1 via a housing 10 containing a motor 9 and bearings 11, 11', and their outer circumferences 12, 12' are lined with rubber.

The guide wheels 4a, 4a', 4b, 4b' have bearings 13
, the rotating shaft 14 , the bearing 13 ′, and the housing 1
It is rotatably attached to the frame 1 via the frame 5. In addition, the protrusions 8, 8' of the guide wheels 4a, 4a', 4b, 4b' have tapered tips, and the driving wheels 2
The grooves a and 2b have a convex shape in the width direction. The height of this protrusion is such that when the electric wire is allowed to run on its own, the outer circumferential portions 12, 12' can be prevented from riding on the electric wire and moving on an incline.

The ballast wheels 7, 7' have ballasts 6, 6' slidably suspended near the circumference by a tenon-tenon groove, and are rotatably mounted on the frame 1.

The above-mentioned relationship between tenon and tenon groove refers to a state in which a protrusion is formed on one member, a hole is provided on the other member, and the protrusion is inserted into the hole and fitted. In this embodiment, as shown in FIG. 6, a portion of the protruding rod 44 near the circumference of the ballast vehicle 7
0, a tenon groove 41 is formed in this tenon 40, a tenon groove 42 is formed in the ballast 6 concentrically with the ballast wheel 7, and a tenon 43 is formed in a part of this tenon groove 42. is formed.

The tenon 40 is fitted into the tenon groove 42, and the tenon 43 is fitted into the tenon groove 41. Due to these fittings, the vertical and horizontal directions are restricted, and the ballast wheel 7 can slide only in the rotational direction.

There are a plurality of cutouts 5 in one ballast vehicle, and the lower cutout 5 from which the ballast 6 is suspended is the sixth cutout.
It has a triangular cross section that is larger than the branch line 25 shown in the figure and the cross section of the steady rest fitting, and while the branch line 25 and the like are accommodated in the notch 5, the ballast 6 is inserted into the ballast car 7. It is possible to pass through the branch line 25, etc., without separating from the branch line 25.

Electrical connection between the motor 9 and the battery 15 is made by a movable electrode 17 formed by a spring 16 provided on the ballasts 7, 7' and an arc-shaped fixed electrode 18 provided on the ballasts 6, 6'. , 7' are connected by a ring-shaped electrode 19 provided on the frame 1 and a brush 20 provided on the frame 1.

Next, the functions of each member of a self-propelled machine according to an embodiment of the present invention will be explained with reference to FIGS. 5, 6, and 7.

FIG. 5 is an explanatory diagram showing the movement of the drive wheel 2 and the guide wheel 4 when the self-propelled machine moves by itself and passes the insulator 23. A weight 22 is attached to the protrusion 8 on the lower half of the guide wheel 4, and the self-propelled machine runs on the electric wire in state A. Now the protrusion 8 on the insulator 23
When contact occurs, a rotational moment acts on B, C,
The state changes in the order of D and E, and when the contact with the insulator 23 is released, the weight 22 returns to state A again. The outer circumferential portion 10 of the driving wheel 2 rides on the insulator 23 and is released from the electric wire 24 .At the same time, the protruding portion of the insulator 23 is accommodated in the notch 3 of the guide wheel 4 , and the protruding portion 8 is attached to the electric wire 24 . The drive wheel 2 is regulated using the guide as a guide and does not come off the electric wire 24.

In FIG. 5, the driving wheel 2 changes from state A to state B.
The state shifts in the order of C, D, and E, and returns to state A again, but the shift from B to C is made by the inertial force of self-propulsion and the driving force of the other drive wheels. That is, when the vehicle moves by itself with the drive wheel 2a in front, the drive wheel 2a is pushed by the driving force of the drive wheel 2b and shifts from state B to state C, while the drive wheel 2b passes through the insulator 23. At this time, B is pulled by the driving force of the driving wheel 2a.
to state C. In any case, the inertia of the self-propelled machine acts unless the self-propelled machine stops.

Figure 6 shows the ballast vehicle 7 and the branch line 25 when passing through the branch line 25 branched from the self-propelled electric line 24.
FIG. 2 is an explanatory diagram showing the relative relationship between

Now, when the self-propelled machine is self-propelled in the direction of arrow A, the branch line 25 is accommodated in the notch 5, and eventually the protruding rod 44
At the same time, a rotational moment about the central axis of the ballast vehicle 7 acts on the ballast vehicle 7, causing the ballast vehicle 7 to rotate in the direction of arrow B. Then, it moves in the order of A, B, and C, and when it reaches state D, it releases the branch line 25,
Without separating the ballast car 7 and ballast 6,
The branch line 25 can be passed through.

FIG. 7 is a schematic explanatory diagram of the relationship among the drive wheels 2, guide wheels 4, ballast vehicle 7, and frame 1 seen from the self-propelled direction when the self-propelled machine passes the rising line 26 branched from the electric wire 24 on which the self-propelled machine is self-propelled. It is.

When the self-propelled machine approaches the rising line 26, the outside of the frame 1 acts as a guide, and while the outside of the frame 1 and the rising line 26 are in contact with each other, the self-propelled machine tilts to the right or left in the direction of travel. The guide wheel 4 is self-propelled, and the rising line 26 is accommodated in the notch 3 of the guide wheel 4, and at the same time as it comes into contact with the protrusion 8, a rotational moment is applied around the central axis of the guide wheel 4 as a fulcrum, and the guide wheel 4 rotates. The rising line 26 passes through the guide wheel 4. Next, as explained in FIG. 6, the vehicle passes through the ballast vehicle 7, and then also passes through the guide wheel 4 at the rear in the direction of travel.

At this time, since the ballast 6 is always located below the electric wire 24, the self-propelled machine will not fall from the electric wire 24.

The guide wheel 4 has the function of ensuring that when the drive wheel 2 passes an obstacle such as an insulator, the V-groove of the drive wheel is temporarily detached from the electric wire, but the V-groove of the drive wheel is fitted into the electric wire again. . Moreover, the notch 3 of the guide wheel 4 is
This refers to the space between the protrusions 8, and is a space that can accommodate at least an obstacle such as an insulator.

The ballast vehicle 7 has the function of always suspending the ballast 6 below the self-propelled electric wire, and the notch 5 is the space between the protruding rods 44 and is a space that can accommodate rising wires, etc. be. Further, it is necessary to fit at least two, preferably three or more protruding rods 44 into the ballast 6.

When the self-propelled machine of this embodiment described above was run on electric wires provided with insulators and branch lines, it was able to easily and stably pass obstacles such as insulators and rising lines.

In this embodiment, the frame 1 has a guiding function for passing obstacles, especially rising lines, and it is preferable that the friction coefficient on the outside of the frame 1 be as small as possible. There are means to improve this, and the frame 1 may be provided with a separate guide. Further, it is preferable that the outer peripheral portion 12 of the drive wheel 2 has a coefficient of friction as large as possible, and in addition to increasing the friction coefficient by using a material such as rubber, there are means to increase the friction coefficient by knurling or the like. Furthermore, the guide wheel 4 does not necessarily have to be coaxial with the drive wheel as long as the tip of the protruding portion 8 projects below the drive wheel 2. Further, the number of notches 3 of the guide wheel 4 may be one or more for each guide wheel 4, and the shape thereof may be a fan shape or a semicircular shape. Furthermore, there is also a means of providing a roller, a disk, etc. at the tip of the protrusion 8 to smoothly rotate the guide wheel 4 even when the protrusion 8 hits the insulator at right angles. Furthermore, the ballast car 7 is fixed to the frame 1 with the ballast 6 in the opposite positional relationship.
There is a way to have a built-in battery. Furthermore, the cutout portion 5 of the ballast car 7 is one per ballast car 7.
In that case, it is necessary to keep the ballast wheel 7 constantly rotating, or to have a means for rotating it when it comes into contact with an obstacle.

Furthermore, the means for sliding and suspending the ballast wheel 7 and the ballast 6 may be by rolling, instead of using friction as in this embodiment, and any means may be used as long as the ballast wheel 7 and the ballast 6 are slidable.

Further, in the present invention, the drive source may be an engine or an air motor other than a motor, or the power source may be supplied from an external source such as an electric wire. Furthermore, the self-propelled machine of the present invention may be equipped with a safety device or a control device, or may be controlled by radio control or the like.

As described above, in the self-propelled machine of the present invention, a notch is formed in the rotatable guide wheel, and the tip of the convex part is made to protrude below the drive wheel, so that the drive wheel can reach the destination without coming off the electric wire when passing an obstacle. Since it can run on its own, there is no need for a complicated control mechanism.

The ballast is slidably suspended from the ballast car, and a space is formed in the ballast car by a notch, and obstacles such as branch lines can be passed through this space, so the center of gravity of the self-propelled aircraft is always maintained downward. This allows it to run stably and safely on its own.

The weight can be reduced because batteries, which account for a large proportion of the total weight of the self-propelled aircraft, can be built into the ballast.

By providing the frame with a guide function, it can easily pass through obstacles.

As mentioned above, the self-propelled machine of the present invention is a self-propelled machine that fully satisfies the purpose of the present invention.
