Abstract

PROBLEM TO BE SOLVED: To secure separation distance from a neighboring electric wire and an overhead earth wire and to make it possible to avoid all obstacles, by providing a balancer capable of turning around a cable, and performing attitude control to a desired auxiliary rail side together with a vehicle body in such a manner that the auxiliary rail can be caught. SOLUTION: A swing motor 10 is attached to a vehicle main body 6, and a balancer 12 is attached to the tip of an arm 11 attached to a rotating shaft interlocked with a motor shaft.

Then, the auxiliary rail wheels 3A to 3D are rotated at the side of any desired right or left auxiliary rail (16L or 16R) and a bypass (auxiliary rail 16) connected to a desired cables 1A, 1B is selected.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an overhead line traveling system for traveling while hanging on overhead lines such as transmission lines, distribution lines, and communication lines, and for maintaining and inspecting overhead lines, overhead lines, and facilities attached to the overhead lines.

[0002]

2. Description of the Related Art In general, overhead lines such as transmission lines, distribution lines, and communication lines are laid over steel towers in accordance with the topography of the installation site and to avoid buildings and the like. 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. In an overhead traveling device used for maintenance and inspection of such overhead wires (for example, an overhead traveling device described in Japanese Patent Application Laid-Open No. 3-89805), for example, overhead traveling in a structure such as a steel tower that suspends the overhead wire. The device carries an auxiliary trajectory serving as a detour, and is provided with a number of operating axes for operating the auxiliary trajectory. When passing through a steel tower, multiple operating axes are operated to pass an auxiliary track corresponding to the bent overhead line, bypass the auxiliary track and transfer to the next overhead line, and continuous inspection and running of the overhead line I was able to do it.

[0003] On the other hand, in the case of a distribution line or a power supply line installed along a railway, there is no sharp bend, and it is about 5 degrees at the maximum. There is also. Therefore, in such a case, even if there is no operation axis corresponding to the bending of the overhead line, there is a demand for a small and lightweight overhead line traveling device that can be easily switched to the overhead line.

[0004] In order to meet such a demand, the inventors have previously proposed the overhead wire traveling device described below in Japanese Patent Application Laid-Open No. 4-334913.

[0005] This overhead traveling device travels with the overhead wire alternately sandwiched by three front and rear and intermediate drive wheels provided on the device body and suspended. It passes through the obstacle using a balancer for controlling the attitude of the apparatus body. For example, to travel through obstacles such as suspension equipment used for power transmission lines, such as suspension insulators, move the balancer to move the center of gravity, and run while changing the balance position with respect to the overhead line. By spirally moving the overhead traveling device, 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 overhead lines such as distribution lines and power supply lines that are installed along a railway without sharp bends.

[0006]

In the case of a distribution line in an urban area in which the overhead traveling line travels along the overhead line, the distribution line is not thick like a transmission line, and the adjacent electric line and the overhead ground line run in parallel. And the distance 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. 3-89)
The overhead traveling line moving device described in No. 805) can move in response to a bend or a T-shaped branch at a support point that suspends the overhead line, but it is difficult to reduce the size and weight because of the large number of operating axes. 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 risk of short-circuiting to a nearby electric wire. In addition, a conventional overhead traveling device (Japanese Unexamined Patent Publication No. 4-33491)
No. 3) has a small number of operation axes and is lightweight and compact, but has a problem that it cannot avoid an obstacle in an overhead line having a sharp bend and a T-shaped branch.

[0007] Therefore, an object of the present invention is to allow the installation of a minimum number of incidental equipment such as a tower or the like that suspends an overhead line or a detour in which an overhead traveling device travels on the overhead line, thereby allowing the operation shaft to operate. An object of the present invention is to provide an overhead wire traveling system that has a very small number of lightweight and small configurations, and that can be freely transferred at a branch point such as a bend at a support point of the overhead wire or a T-shaped branch.

The driving wheels 2C and 2D oppose each other, and the driving wheels 2A to 2D are rotated by the driving mechanism 8 which transmits the driving from the driving motor 9 with the overhead wire 1 interposed therebetween.

Next, 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 the auxiliary rail 16L and the overhead wire 1
The auxiliary rail 16R is attached to B in advance.

In this case, when the traveling direction is reversed from the illustrated overhead line 1A to the overhead line 1B via the branch point and returned, first, from the point A, the overhead line traveling device 50 moves the auxiliary rail wheels 3A to 3D on the auxiliary rail 16L. It travels by rotation and arrives at point B via a branch point. When the vehicle arrives at the point B, the turning motor 10 is driven by an instruction from the outside and the overhead traveling device 50
Is rotated about the overhead wire 1, is swung by swinging the balancer 12 at the tip of the arm 12, and the posture is reversed.
