DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an overhead traveling system for traveling while being suspended on overhead lines such as transmission lines, distribution lines, and communication lines, for example, for maintenance and inspection of overhead lines, the vicinity of the overhead lines, and facilities associated with the overhead lines. About the system.

[0002]

2. Description of the Related Art Overhead lines, such as transmission lines, distribution lines, and communication lines, are generally hung over steel towers in accordance with the topography of the installation site and to avoid buildings. For this reason, the overhead line may be erected by bending it up, down, left, right, up and down with the steel tower as a breakpoint.

[0003] In an overhead wire traveling device (for example, an overhead wire moving device described in JP-A-3-89805) used for maintenance and inspection of the overhead wire, for example, in a structure such as a steel tower that suspends the overhead wire, The catenary traveling device carries an auxiliary trajectory serving as a detour, and is provided with a number of operation axes for operating the auxiliary trajectory. Then, when passing through the tower, multiple operating axes are operated to pass the auxiliary track corresponding to the bending overhead line, transfer to the next overhead line while bypassing the auxiliary track, and continuously check the overhead line I was able to run.

[0004] On the other hand, a distribution line or a power supply line installed along a railway does not have a sharp bend, is at most about 5 degrees, and furthermore, in some cases, a damaged section is known at the time of maintenance and inspection. . Therefore, in such a case, even if there is no operation axis corresponding to the bending of the electric wire, there is a demand for a small and lightweight overhead wire traveling device that can be easily transferred to an overhead wire.

In order to meet such a demand, the inventors have previously proposed an overhead wire traveling apparatus as disclosed in Japanese Patent Application Laid-Open No. 4-334913, and its outline will be described below.

The overhead traveling device travels in a state of being suspended by alternately sandwiching the overhead wire between three front and rear and intermediate drive wheels provided on the device main body, and uses a balancer for controlling the attitude of the device main body. Pass through obstacles.

For example, in order to travel through an obstruction caused by overhead wire support equipment such as a suspension insulator used for a power transmission line, the balancer is moved to move the center of gravity, and the balance position with respect to the overhead wire is changed. After traveling, the overhead wire traveling device is spirally moved, and the three drive wheels pass one by one, avoiding the opposite side of the obstacle. This overhead traveling device has a small number of operating axes, is lightweight and small, and can avoid obstacles such as suspension insulators in an overhead line that is not steeply bent, such as a distribution line or a power supply line installed along a railway.

[0008]

In the case where the overhead line traveled by the overhead traveling device is an urban distribution line, the distribution line is not thick like a transmission line, and the adjacent electric line and the overhead ground run in parallel. The distance to the line is short. The distribution line in the city area is bent or branched at the support point of the overhead line.

However, a conventional overhead traveling device (Japanese Patent Laid-Open No.
-89805, the overhead line moving device)
Although it is possible to move in response to a bend or a T-junction at a support point that suspends the overhead line, it is difficult to reduce the size and weight because of the large number of operating axes.

In addition, since the diameter of the electric wire is smaller than the weight of the overhead traveling device, the slack is large, and there is a concern that a short circuit with a nearby electric wire may occur.

Furthermore, a conventional overhead traveling device (Japanese Patent Laid-Open No.
No. 334913) has a small number of operation axes and is lightweight and small, but has a problem that it cannot avoid an obstacle in an overhead line having a sharp bend or a T-shaped branch.

According to the present invention, in order to solve the above-mentioned problems, it is permissible to mount a minimum number of additional facilities such as a detour on which the overhead traveling line travels on a structure such as a steel tower which suspends the overhead line or an overhead line. It is another object of the present invention to provide an overhead traveling system that has a very small and lightweight structure with a very small number of operating axes, and that can move at a branch point such as a bend at a support point of the overhead line or a T-junction in any direction. .

As shown in FIG. 6, when there is a structure 20 such as a steel tower in the traveling direction of the overhead wire traveling device 50 with respect to the overhead wire 1, if the overhead wire 1A is provided with an auxiliary rail 16L and the overhead wire 1B is provided with an auxiliary rail. 16R is attached in advance.

In this case, when the traveling direction is reversed from the overhead line 1A shown in the figure to the overhead line 1B via the branch point and returned, first, from the point A, the overhead line traveling device 50 travels on the auxiliary rail 16L by the rotation of the auxiliary rail wheels 3A to 3D. Then, the vehicle reaches the point B via the branch point. When reaching the point B, the turning motor 10 is driven by an external command, and the overhead wire traveling device 50 rotates about the overhead wire 1, and the balancer 1 at the tip of the arm 12 is rotated.

Also, a structure 2 such as a steel tower suspending the overhead wire 1
At 0, when the overhead wire traveling device 50 moves on the detour (the auxiliary rail 16), the auxiliary rail 16 pushes and spreads the auxiliary rail wheels 3A to 3D, and accordingly, the auxiliary rail wheels 3A to 3D are pinched by the pinching mechanism attached to the chassis main body 6. The drive wheels 2A to 2D are released from the overhead wire 1. Thus, the drive wheels 2 </ b> A to 2 </ b> D are detached from the overhead line 1 as the overhead traveling device 50 transfers to the auxiliary rail 16.

Further, in a structure 20 such as a steel tower that suspends the overhead line 1, when the overhead traveling device 50 moves over the detour (auxiliary rail 16), the auxiliary rail wheels 3A to 3D are tapered at both ends. 16 can be easily inserted without slipping, and can travel without slipping even when the overhead wire traveling device 50 runs on an inclined detour (the auxiliary rail 16).

Even if there is light rain, it can operate normally.

FIG. 7 is a schematic diagram showing a basic configuration of a first embodiment of a catenary traveling system according to the present invention.
FIG. 9 is a detailed view of the mechanism of the overhead traveling device 51a of the overhead traveling system 51 according to the embodiment. The main parts of the mechanism of the overhead wire traveling device 51a, the auxiliary rails 51b, and the overhead wire 1 are the same as those in the basic configuration described above, and the description thereof is omitted here.

First, as shown in FIG. 7, an overhead wire 1 is extended in two rows above and below a structure such as a steel tower, and an auxiliary rail 51c is provided to move the overhead wire traveling device 51a from the upper overhead wire to the lower overhead wire. Is bent while appropriately imparting a twist from the upper part to the lower part of a structure such as a steel tower.
In this case, the shape of the auxiliary rail 51c is formed such that the thickness t gradually changes in the speed change section 51d. Further, when a non-slip tooth profile is provided in all sections, the size and pitch of the tooth profile are determined by the thickness t of the auxiliary rail 51c in that section.
In the speed change section 51d, the size and pitch of the tooth profile are formed so as to gradually change in accordance with changes in the thickness t of the auxiliary rail 51c.

As shown in FIGS. 8 (a) and 8 (b), the engagement radius r of the auxiliary rail wheel 52 is smaller than the auxiliary rail 51c.
The auxiliary rail wheel 52 has a valley-shaped engagement portion with the auxiliary rail 51c so as to differ depending on the thickness t of the auxiliary rail 51. Further, a differential gear 53a is provided at a portion which is distributed to the front and rear of a driving unit 53 which transmits a rotational force to front and rear auxiliary rail wheels 52f and 52r. Furthermore, when the anti-slip tooth profile is provided on the auxiliary rail wheel 52, bevel gears 52b and 52c are arranged face-to-face with the small gear 52a interposed therebetween so that the gear pitches are uniform.

Further, as shown in FIG. 9A, the engagement radius r1 is large (the auxiliary rail 51c in the parallel movement section).
Is set in accordance with the thickness t1), the engagement radius r
1 is set to be substantially the same as the radius R1 of the drive wheel 2 of the overhead wire 1. Further, as shown in FIG. 9B, the meshing radius r2
Is small (set in accordance with the thickness t2 of the auxiliary rail 51c in the uphill section), the meshing radius r2 is
The radius R2 is 2a, and the thickness t2 of the auxiliary rail 51c is the gear of the small gear 52a.

You can go back and forth between different floors of the building.

8 (a) and 8 (b), the amount of engagement of the auxiliary rail wheel 52 into the valley-shaped engagement portion varies depending on the thickness t of the auxiliary rail 51c. The radius r can be changed. Since the relationship between the traveling speed of the overhead traveling device 51a and the traveling propulsion becomes variable, the traveling speed can be reduced by lowering the traveling speed when the overhead traveling device 51a moves on the auxiliary rail 51c, and the inclination (vertical inclination) can be increased. Auxiliary rail 5)
You can climb 1c.

Further, in the shift section 51d, the meshing radii r1, r of the front and rear auxiliary rail wheels 52f, 52r are set.
Even if 2 is different, the average traveling speed is obtained by the differential gear 53a of the drive unit 53, so that the front and rear auxiliary rail wheels 52f and 52r do not slip with the auxiliary rail 51c.

In the horizontal movement section, as shown in FIG. 9A, the bevel gears 52b and 52c mesh with the thickness t1 of the auxiliary rail 51b, and the meshing radius r1 is equal to the driving wheel 2 of the overhead wire 1.
Of the overhead wire traveling device 51a
When traveling from the vehicle to the auxiliary rail 51b, the traveling speed of the overhead wire 1 and the traveling speed of the auxiliary rail 51b in the horizontal movement section are the same. Further, in FIG. 9B in the uphill section (deceleration section), the meshing radius r2 is the radius R2 of the small gear 52a.
Since the thickness t2 of the auxiliary rail 51c is the tooth thickness of the small gear 52a, the small gear 52 of the auxiliary rail 51c is
The meshing with a and the meshing with the bevel gears 52b and 52c are continuous.

According to the present embodiment, first, in FIG. 7, the overhead traveling device 51a can move up and down structures such as electric poles and steel towers. And the floor can be traversed on different floors of the building, so that the entire building can be inspected by one overhead traveling device 51a.

Next, as shown in FIG.
The means for changing the radius of engagement r with the secondary rail 2 is the auxiliary rail 51d.
Since only the thickness t is changed, the overhead traveling device 51a is inexpensive.
Speed ratio can be adjusted. Further, since the traveling propulsion force can be increased only when the overhead traveling device 51a moves on the inclined auxiliary rail 51c, the drive having a larger capacity than necessary for climbing a slope without lowering the traveling speed in the horizontal direction. There is no need to prepare a source.

Further, at the point where the meshing radius r of the auxiliary rail wheels 52 changes, the front and rear auxiliary rail wheels 5
Since 2f and 52r do not slide on the auxiliary rail 51c,
The auxiliary rail wheels 52 and the auxiliary rail 51c do not wear or vibrate. In FIG. 9 (a), there is no speed difference between the overhead wire 1 of the overhead wire traveling device 51a and the auxiliary rail 51c, and the vehicle travels smoothly without generating vibration.

In FIG. 9 (b) of the uphill section, the overhead wire traveling device 51a uses a small gear 52a and an auxiliary rail 51c.
Climbing up the hill, and small gear 5
The meshing of the auxiliary rail 51d continuously and smoothly shifts from 2a to the bevel gears 52b and 52c.

As shown in FIG. 11, a circulating belt 65a is formed on the edge of the sled-shaped guide 65 so as to be freely circulated along the edge.
By transmitting power from 3a to the drive pulley 65b of the circulation belt 65a, the circulation belt 65a is driven to circulate.

The relationship between the drive wheel 63 and the output roller 63a has a reduction ratio due to the difference in radius,
It has a function of amplifying the driving force of 5a. The sled shape guide 65 has a restoring spring 65c on the side to be clamped, and is supported by a clamping mechanism 64 so as to be able to translate freely by the guide 65d. The driving pulley 65b contacts the output roller 63a only when the sled-shaped guide 64 is pushed and spread against the restoring force of the restoring spring 65c by receiving a force on the side that is pushed and spread when nipping the support component 61a and going over. Since they are in contact with or mesh with each other, power is transmitted from the drive wheels 63 to the circulation belt 65a. further,
An edge is also provided around the balancer 12, and the circulation belt 69 is configured to be freely circulated along the edge.

Next, the operation of the overhead traveling device 60a of the overhead traveling system 60 configured as described above and the overhead traveling method will be described with reference to FIGS. 10 and 11. FIG.

First, in FIG. 10, the overhead wire 61 is supported by a simple supporting part 61a, and the overhead overhead wire 6
In a structure 62 such as a steel tower or a utility pole in which the overhead wire 1c and the overhead wire 61c are straight, the sled-shaped guide 65 attached to the side of the flange of the drive wheel 63 can be slid over the support component 61a to sequentially get over. .

It should be noted that a structure 66 such as a steel tower which suspends a steeply bent or branched overhead wire and a structure 67 such as a steel tower having a support form in which the overhead wire cannot be easily stepped over.
Are provided with the auxiliary rails 68 (68a, 68b), so that the desired overhead wire 6
It crosses along the auxiliary rail 68 connected to 1.

Further, in FIG.
5 can smoothly slide on the support component 61a without friction. The circulating belt 65a of the sled-shaped guide 65 generates a force to step on the support component 61a by itself. Since the circulating belt 65a generates a larger force than the driving wheel 63 does, the cycling belt 65a can step over the supporting component 61a with a strong force. When the balancer 12 abuts on the surrounding structure when stepping over the support component 61a, the friction is reduced by circulating the circulation belt 69 between the balancer 12 and the abutting structure.

Normally, when traveling on the overhead wire 61, the sled shape guide 65 is at the reference position by the restoring force of the restoring spring 65c, and the driving pulley 65b is
a does not come into contact with or engages with the a, so that power from the drive wheels 62 to the circulation belt 65a is not transmitted. When traveling on the overhead wire 61, the circulation belt 65a for moving over the support component 61a does not operate.

According to the embodiment of the present invention, in FIG.
The overhead wire 61 is supported by a simple supporting part 61a, and the overhead wire 61b before the transit and the overhead wire 61c to which the transit is performed
In a structure 62 such as a steel tower or a utility pole having a substantially straight line, it is not necessary to provide the auxiliary rail 68 because the warp-shaped guide 65 can be used to get over the structure. Thereby, the installation cost and the maintenance cost of the auxiliary rail 68 can be saved.

In FIG. 11, the circulating belt 65a
Generates a greater force than can be overcome by the drive wheel 63 and overshoots the support component 61a with a strong force. Therefore, the normal traveling speed is not reduced and the traveling propulsion force is not increased. There is no need to prepare a large driving source.

Furthermore, since the circulating belt 69 reduces friction even when the balancer 12 abuts on the surrounding structure, the load on the drive source is reduced, and the abutment portion can be slipped over while sliding. Also, when traveling on the overhead wire 61,
Since the circulation belt 65a does not operate, the circulation belt 65a
Energy consumed due to friction or the like can be saved as compared with the case where the motor is always idle.

By loosening the overhead wire 1
The overhead wire traveling device 70a can be brought closer to the inspection point below.

In FIG. 13, when the overhead wire 1 is cut, a new overhead wire 1r is lowered from above, thereby forming a new overhead wire 1r.
