2. Description of the Related Art A sliding plate of a pantograph is a member that is disposed on the pantograph and keeps in contact with an overhead wire during traveling of a train or the like to collect current. This sliding plate gradually wears due to sliding contact with the overhead wire as the train travels, and is damaged by ice droplets attached to the overhead wire.If the sliding plate wears beyond a certain limit, it can be used more. Can no longer be used and needs to be replaced with a new one.

For this reason, conventionally, such a pantograph slide plate has been so arranged that an automatic measuring device disposed at an appropriate position of the overhead wire measures the amount of wear and the degree of damage to determine the time for replacement. This automatic measuring device includes a pair of right and left push-down guides for separating a slide plate of a pantograph from an overhead line as shown in Japanese Patent Application Laid-Open No. 2-26202, and a plurality of guides attached to a frame disposed orthogonal to the overhead line. The ultrasonic sensor is used to measure the wear amount and the degree of damage of the slide plate, and the measurement data is managed by a personal computer.

As shown in FIG. 1, an automatic measuring apparatus 10 for a pantograph slider according to the present invention has parallel overhead wires 20 and 21.
Is arranged at an appropriate position above the vehicle, and is configured to detect the amount of wear and the degree of damage of the slide plate 32 of the pantograph 31 that contacts the overhead wire 20 when the train 30 travels. The automatic measuring device 10 is suspended from a support 40 via an insulator 50, and a sliding plate 32 is attached to the overhead wire 20.
The train 30 that travels while contacting the sensor transmits ultrasonic waves from an ultrasonic sensor to be described later to the sliding plate 32 that passes immediately below the ultrasonic sensor, receives the ultrasonic waves, and performs data processing by the data processing device 60. The damage state of the slide plate 32 detected by the transmission of the ultrasonic waves is indicated by the management center 70.
Is managed by a personal computer 71 installed in the computer. The personal computer 71 transmits the data measured by the ultrasonic sensor 12 to the train 30 on which the pantograph is mounted.
It is made to accumulate and manage along with the car number. Therefore, the administrator can determine the replacement time of the sliding plate 32 based on the measurement data accumulated in the personal computer 71 and the traveling distance data of the train 30 and the like.

As shown in FIGS. 2 to 4, the automatic measuring device 10 is insulated by the insulator 50 as described above at an appropriate position of the overhead wires 20 and 20 so as to be orthogonal to the overhead wires 20 and 20. A mounting frame 11 having a plurality of rows (four rows in this embodiment) of sensor mounting bodies 11A and a plurality of ultrasonic sensors 12 mounted on the lower surface of each sensor mounting body 11A of the mounting frame 11 are provided. And a measuring means. Each sensor mounting body 11A of the mounting frame 11 is shown in FIG.
As shown in the figure, the elements are arranged so as to be gradually narrowed by a constant pitch in the traveling direction. The sliding plates 32 are provided by the ultrasonic sensors 12 arranged in four rows in this manner.
In such a case, it is difficult to instantaneously detect a damaged portion of the sliding plate 32 passing immediately below each ultrasonic sensor 12 in the sensor mounting body 11A in one row over the entire length. Even so, the detection leak is compensated by the ultrasonic sensor 12 of the other remaining sensor mounting body 11A.

As shown in FIG. 5, the overhead lines 20, 20 are wired at a predetermined angle with respect to the line direction. By inclining the overhead wires 20, 20 with respect to the track direction in this way, the contact position between the sliding plate 32 and the overhead wires 20, 20 gradually shifts as the train 30 travels, and a single row of sensor mounting bodies Even if any of the ultrasonic sensors 12A of 11A is located directly above the overhead wire 20 and cannot measure the position, the position of the ultrasonic sensor 1 in another row is not considered.
2 ensures that the measurement can be made.

The structure of the slide plate 32 to be measured is as shown in FIGS. That is, the sliding plate 32
In the same manner as in the related art, the reference plate portion 32A includes a pair of sliding plate portions 32B arranged side by side with a gap in the longitudinal direction of the upper surface of the reference plate portion 32A. The reference plate 32A is
The sliding plate portion 32B is a portion that does not come into contact with the wires 0 and 20 at all and does not cause wear and damage.
It is a part that is constantly in contact with 0, 20 and is worn and damaged.

The running of the train 30 causes the sliding plate 3
2 passes immediately below the ultrasonic sensor 12 attached to the lower surface of the sensor mounting body 11A.
As shown in FIG. 8, the ultrasonic wave transmitted from
The ultrasonic sensor 12 measures the distance required to reach the reference surface (upper surface) of the 2A and the upper surface of the sliding plate portion 32B and to be reflected from each part and received by the ultrasonic sensor 12. For example, the ultrasonic sensor 12
Are the distances ha, from both ends of the reference plate portion 32A.
hb and the distance h to the slide plate portion 32B are measured, and the measured data is subjected to data processing by the data processing device 60 and transmitted to the personal computer 71, and the personal computer 71 transmits the received distance data ha and hb to the personal computer 71. Based on the calculated inclination of the sliding plate 32, the distance to the reference plane at the position of each ultrasonic sensor 12 is corrected. The difference between the corrected reference distance and the distance h to the upper surface of the sliding plate portion 32B becomes the thickness of the sliding plate portion 32B, whereby the wear amount and the degree of damage of the sliding plate 32 can be detected.

FIG. 8 shows an automatic measuring apparatus 10 according to this embodiment.
As shown in FIG. 1, an ultrasonic sensor 13 for temperature calibration is provided. The ultrasonic sensor 13 is provided to measure an accurate distance when the propagation speed of the ultrasonic wave changes due to the ambient temperature. The temperature is monitored and corrected appropriately.

The apparatus for automatically measuring a pantograph sliding plate according to the present invention comprises a plurality of rows of sensor mounts which are disposed at appropriate positions of the overhead line forming a predetermined angle with respect to the track direction and are insulated from the overhead line. A plurality of distance sensors attached to the lower surface of the sensor mounting body, respectively, and during traveling of a train or the like that travels by directly contacting a sliding plate of a pantograph with an overhead wire, the distance sensor passes directly below the distance sensor. When transmitting, the transmission wave is transmitted to the slider in a state of being in direct contact with the overhead wire, and the distance until the reflected wave reflected from the upper surface of the slider and the reference surface is received is measured. If the wear amount of the sliding plate or the presence or absence of damage is detected based on the difference, all of them are included in the present invention.
