[Prior art]
DESCRIPTION OF RELATED ART Conventionally, what was described in Unexamined-Japanese-Patent No. 9-226417 is known as a trolley line inspection apparatus. This is a traveling device having a traveling roller that rolls on an electric wire when suspended, a sensor for inspection supported by the traveling device, and control for processing inspection information from the sensor and storing the information in an external storage device. The traveling device and the controller box are connected to each other by a support in a cantilevered state on one side. By connecting the traveling device and the controller box on one side with a support, a support such as a movable bracket or a curve fitting which hinders traveling is avoided.
[0003]
[Problems to be solved by the invention]
However, in the above-mentioned conventional inspection apparatus, since the connection between the traveling device and the controller box is cantilevered, the traveling is likely to be unstable, and depending on the structure of the bracket, there is a problem that it cannot be avoided. There are points.
Accordingly, an object of the present invention is to provide a train line inspection device that can avoid any expected obstacle without any trouble, and can stably run on its own, and can quickly execute an inspection. .
[0004]
[Means for Solving the Problems]
In the present invention, in order to solve the above-mentioned problem, the traveling unit 2 that runs on the suspension line M and the traveling unit 2 via a plurality of support arms 4 are connected to the traveling unit 2 below the trolley wire T. The train line inspection device 1 is configured to include the suspended and moved control unit 3. The traveling unit 2 includes a motor-driven traveling roller 6 that rolls on the suspension line M, and a hook unit 7 that is engaged with and disengaged from an engaging portion 4 a on the upper part of the support arm 4 by a hook driving motor 9. Is provided. The plurality of support arms 4 are provided at least in the traveling direction of the apparatus at intervals from each other, and are connected to the control unit 3 at the lower end so as to be able to stand up and fall over, and to be able to stand up and fall down by the arm drive motor 10. Then, the upper engaging portion 4a is engaged with the hook portion 7 of the traveling portion 2 at the upright position, and avoids an obstacle crossing the course at the overturned position. The traveling unit 2 and the control unit 3 are provided with an optical detection device 13 for detecting an obstacle on the traveling direction side of each support arm 4 at a position near the traveling direction side of each support arm 4. The control unit 3 receives the obstacle detection signal from the optical detection device 13 and issues a detachment operation command to the hook drive motor 9 and issues a tipping operation command to the arm drive motor 10. A control device for issuing a return command to the motor 9 and the arm drive motor 10 is provided.
[0005]
The traveling unit 2 runs on the suspension line M by itself, and the control unit 3 is suspended by the traveling unit 2 by the support arm 4 and moves below the trolley wire T. While moving along the suspension line M, various inspection lines are inspected by an inspection device such as an eddy current sensor 14 mounted on the traveling unit 2, for example. If there is an obstacle such as the movable bracket B crossing the course during traveling, the optical detection device 13 in front of each support arm 4 sequentially detects this, and based on the detection signal, the hook portion 7 turns the support arm 4, the support arm 4 is released, and when the support arm 4 falls down, the vehicle continues running smoothly while avoiding obstacles. Since the support arms 4 individually and sequentially fall down as they proceed, the control unit 3 is supported by another support arm 4 while one or two support arms 4 are falling.

The support arm 4 is pivotally attached to the control unit 3 at the lower end so as to stand upright outside the suspension line M and to fall horizontally outside the suspension line M. The support arm 4 is erected and turned over by the arm drive motor 10, and the upper engaging portion 4 a engages with the hook 7 of the traveling portion 2 at the erected position, and removes obstacles crossing the course at the overturned position. Configured to avoid.
[0010]
In this embodiment, the engaging portion 4a of the support arm 4 is a long hole that is long in the axial direction. The hook portion 7 includes a hook pin 11 that engages with the elongated hole 4a and a link 12. The hook pin 11 is connected to the base 5 of the traveling section 2 at the base end so as to be able to stand up and fall over, and to rise and fall by the forward / reverse rotation of the drive motor 9 via the link 12. The hook pin 11 engages with the elongated hole 4a of the support arm 4 to suspend and support the support arm 4 at the upright position protruding horizontally from the traveling portion 2, and supports the support arm 4 through the elongated hole 4a at the inclined position facing downward. The arm 4 is freely rotatable to allow its overturn. The hook pin 11 is provided at its tip with an engaging projection 11a that projects upward in the upright state and engages with the edge of the elongated hole 4a.
[0011]
The traveling unit 2 and the control unit 3 each have a light emitting device 13a and a light receiving device 13b for detecting an obstacle on the traveling direction side of each support arm at a position near the traveling direction side of the support arm. An apparatus 13 is provided.
[0012]
The control unit 3 receives the obstacle detection signal from the optical detection device 13 and issues a detachment operation command to the hook drive motor 9 and issues a tipping operation command to the arm drive motor 10. A control device (not shown) for issuing a return operation command to the motor 9 and the arm drive motor 10 is provided.
[0013]

The inspection device 1 separates the traveling unit 2 from the control unit 3 and arranges the traveling unit 2 on the suspension line M, and places the roller 6 on each suspension line M. Then, with the hook pin 11 standing upright, the engaging section 4a of the support arm 4 standing up from the control section 3 is hooked on this. When the apparatus is started, the traveling roller 6 is rotated by the roller drive motor 8 and traveling on the suspension line M to the right in FIG. . As shown in FIG. 4, when there are obstacles such as the movable bracket B and the curve fitting A crossing the course during traveling, the optical detection device 13 in front of each support arm 4 individually detects this. Based on the detection signal, the corresponding hook drive motor 9 operates, the hook pin 11 falls down, and the support arm 4 is released through the elongated hole 4a of the support arm 4. Then, the corresponding arm drive motor 10 operates, and the support arm 4 falls down horizontally, thereby continuing to run smoothly while avoiding obstacles sequentially. When the support arm 4 passes through the obstacle, the support arm 4 stands up and returns, and the hook pin 11 stands up and engages with the elongated hole 4a. Since the support arms 4 individually fall down sequentially as they progress, and return, the controller 3 is supported by the other support arms 4 while one or two support arms 4 are falling down.
In addition, when the present invention is applied to a train line in which the suspension line M is a single line, the number of traveling rollers can be changed to correspond to this without changing the basic configuration of the train line inspection device of the above embodiment. This can be accommodated by making changes.
