Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a trolley wire traveling device which is attached in a suspended state to a trolley wire installed on a train line and which is self-propelled in the longitudinal direction thereof, for example, wear and distortion of the trolley wire. It is used in order to carry out the inspection efficiently by carrying the detection device of the above.

[0002]

2. Description of the Related Art In a trolley wire installed on a train line,
The distortion and wear hinder the current collection from the pantograph, and regular inspections are regularly performed to avoid these situations.

In the conventional inspection method, however, in addition to using a trolley wire test vehicle, an inspector visually checks the trolley wire in the erected state for distortion and wear while walking along the railroad track, and thus has a poor crimping efficiency. In particular, the trolley wire is erected at a high place and the erection over a long distance requires a lot of time and labor.

Therefore, it is conceivable that a self-propelled traveling device equipped with a device for detecting the distortion and wear of the trolley wire is run along the trolley wire for efficient inspection.
The trolley wire is supported by the catenary wire by being sandwiched by the grooves formed on both sides by a large number of trolley wire supports such as hangers arranged at regular intervals in the length direction. Since the line support becomes an obstacle and hinders traveling, it is extremely difficult to provide a traveling device that can travel by itself along the trolley wire.
There was a problem.

[0005]

SUMMARY OF THE INVENTION The problem to be solved by the present invention is that there is a self-propelled traveling device that can be equipped with a device for detecting the distortion and wear of the trolley wire that can be self-propelled along the trolley wire. The point is not to.

[0006]

SUMMARY OF THE INVENTION According to the present invention, a traveling device main body having an elongated base and a pair of engaging members which engage with grooves formed on both sides of a trolley wire whose distance is variable. At least three suspension mechanisms, which have retaining rings, are arranged on the base at appropriate intervals in the longitudinal direction in a straight line and the locking wheels are aligned on one plane, and a traveling wheel in contact with the lower surface of the trolley wire. A traveling mechanism that is installed on the base, a detector that is installed in front of each suspension mechanism and that detects a support of a trolley wire, and an opening / closing drive mechanism that changes the interval between the locking wheels and the detector. And a control circuit that outputs a drive signal for the opening / closing drive mechanism based on a signal from.

An object of the present invention is to provide a self-propelled trolley wire traveling device which can be equipped with a detection device for distortion and wear of the trolley wire.

[0008]

[Operation] A pair of locking wheels arranged so as to oppose each suspension mechanism are respectively fitted into and sandwiched in the suspending grooves formed on both sides of the trolley wire, thereby suspending the suspension wire on the trolley wire, The traveling wheel of the traveling mechanism that is brought into contact with the lower end of the trolley wire is rotated to travel along the trolley wire. In addition, when traveling, the detectors provided in front of each suspension mechanism detect obstacles such as supports laid in the groove of the trolley wire, and the detection signal detects the distance between the locking wheels of each suspension mechanism. It travels while passing through obstacles by expanding and contracting sequentially through a control circuit and a drive mechanism.

Therefore, even if the suspended state is released, the remaining three suspension mechanisms will surely maintain the suspended state for traveling, so continuous traveling is possible in an extremely stable state, but at least three suspension mechanisms are provided. It's enough. Furthermore, in the present embodiment, the gap between the locking wheels 22, 22 provided at the front end of the locking tools 25, 25 is changed by opening and closing the locking tools 25, 25. It goes without saying that another configuration may be used as long as the interval can be changed.

[0020]

According to the present invention, the abacus ball-shaped locking wheels, which are arranged so as to face the respective suspension mechanisms, are fitted and clamped in the suspending grooves formed on both sides of the trolley wire. By doing so, you can hang it on the trolley wire and rotate the running wheels that are in contact with the lower end of the trolley wire to run.In addition, obstacles such as ears that hold the trolley wire at the time of running are suspended by each suspension mechanism. It is detected by a detector provided in front of, and by this detection signal, it is possible to continuously run by sequentially opening and closing the locking tool of each suspension mechanism through the control circuit and the drive mechanism to pass the locking tool of each suspension mechanism. Various inspections can be performed very efficiently by installing a detection device for distortion and wear.
