BACKGROUND OF THE INVENTION
The present invention relates to a train wire overhead structure, a train line inspection apparatus, and an inspection method that are easy to inspect.
[0002]
[Prior art]
Electric railways including feeders, suspension lines, and trolley lines for power supply in electric railways are installed along the railway lines, and the electric trains are supplied with electricity from the electric lines via pantographs. The inspection of the trolley wire on which the pantograph slides directly is performed by a measuring device mounted on an electric inspection vehicle or an electric track comprehensive test vehicle that runs on the track. However, since the train lines and accessory fittings other than the trolley line are located away from the trolley line, they cannot be inspected by the same measuring device as the trolley line. Therefore, for these, a time zone in which the train does not pass mainly at night is provided, and maintenance personnel get on a maintenance vehicle or the like and perform visual inspection separately.

[0008]
As shown in FIGS. 1, 5, and 6, the inspection device 11 can run on the electric wire 2 when the suspension wire 1 and can control this wirelessly by a controller (not shown) on the ground. The inspection device 11 includes a controller box 13 with a built-in control device 12 and a traveling device 14 that suspends the controller box 13 and travels on the electric wire.
[0009]
The base end of the cantilevered support shaft 16 is fixed to the upper end portion of the support column 15 fixed vertically to the side surface of the controller box 13 so as to extend horizontally above the controller box 13. The other end side of the support shaft 16 is fixed to the side surface of the traveling device 14. The traveling device 14 is configured by connecting a traveling unit 17 on the suspension line and the traveling unit 18 on the electric wire, which have substantially the same configuration, with a connecting member 19.
[0010]
A pair of traveling rollers 21 and 22 are installed on the frame 20 of the traveling units 17 and 18 at positions separated from each other in the front-rear direction. One traveling roller 21 on the feeder running section 18 side is a driving roller and is rotated by a traveling drive motor 24.
[0011]
The damage detector 25 detects a damaged state of the electric wire 2 when the suspension wire 1 is located close to the lower side by an eddy current, and is attached to the center portion of the frame 20. A rack 26 extending vertically is fixed to the side surface of the damage detector 25. The rack 26 meshes with a pinion gear 28 on the shaft of a stepping motor 27 fixed to the frame 20. The damage detector 25 is movable up and down by driving the stepping motor 27, and can change the distance between the suspended wire 1 and the feeder 2 located below. The traveling units 17 and 18 are provided with various traveling sensors (not shown). The traveling sensor detects, for example, a sleeve, a connector, or the like that is attached to the suspension line 1 or the feeder line 2 and becomes an obstacle to the damage detector 25, operates the stepping motor 27 via the control device 12, and detects damage. This is for retracting the container 25 to a predetermined position.
[0012]
A radiation thermometer 28 is attached to the front surface of the frame 20. The radiation thermometer 28 measures the temperature of the connector 7 on the suspension wire 1 or feeder 2 and sends it to the control device 12. The control device 12 determines whether the connector 7 is good or bad by comparing this with the normal temperature of the connector 7 stored in the storage device in advance.
[0013]
A CCD camera 29 is attached to the controller box 13, which shoots the hanger 4 and the connector 7, and automatically inspects the image processing system for deformation, disconnection, looseness, wire breakage, and the like.
[0014]
Further, as shown in FIG. 7, the traveling device 14 includes a feeding branch inspection sensor 30. That is, the traveling rollers 21, 22, 21, and 22 are used as four terminals, the pair of left and right traveling rollers 21 and 21 are voltage terminals, and the other pair of left and right traveling rollers 22 and 22 are current terminals. A current is supplied from the measurement power source 31 to the voltmeter 22, and the voltage between the running rollers 21 and 21 is measured by the voltmeter 32. A normal voltage between the traveling rollers 21 and 21 including the branch line 5 is measured and stored in advance, and this is compared with the measured voltage to automatically determine pass / fail.
[0015]
Thus, the inspection device 11 of this embodiment is used by running the traveling rollers 21 and 22 of the traveling device 14 on the electric wire 2 on the suspension wire 1 for self-running. The damage detector 25 having an eddy current sensor moves along the suspension wire 1 and immediately above the electric wire 2 and detects a decrease in the cross-sectional area due to corrosion, wear, etc. of the electric wire 2 when the suspension wire 1. Further, a rotary encoder (not shown) rolls on the suspension line 1 or the feeder line 2 and measures the travel distance from the base point. Data from the damage detector 25 and the rotary encoder is processed by the control device 12 and stored in an external storage device such as an IC memory card. Obstacles on the electric wires that obstruct travel, such as straight sleeves and connectors, are detected by a travel sensor. When the traveling sensor detects an obstacle on the suspension line 1 or the feeder line 2, obstacle data is generated, and this is received by the control device 12 to issue a drive command to the motor 27 to suspend the damage detector 25. The overhead wire 1 is moved away from the electric wire 2 and retracted. Further, the support clamp 8 that supports the wire when the suspension wire 1 passes the inspection device 11 without any trouble. A ground controller (not shown) issues a wireless command to the control device 12 of the inspection device 11 and controls the motors 24 and 29 to move the inspection device 11 forward, backward, stop, and retract and return the damage detector 25. Various operations are performed, and measurement start, stop, reset, etc. of the rotary encoder are controlled.
