本発明は、トロリ線の摩耗量、軌上高偏位ならびに対軌
条振れ角偏位（軌条中心に対する左右偏位）を−トロリ

たトロリ線の検測゛装置に関するものである。[Detailed Description of the Invention] [Technical Field] The present invention aims to improve the wear amount of a contact wire, track height deviation, and run-out angle deviation (lateral deviation with respect to the rail center) over the entire line of the contact wire. This invention relates to a contact wire inspection device that continuously and simultaneously measures and records the contact wires.
電車線等のトロリ線は、常時集電用シューの摺動による
摩耗や、トロリ線の緊張の緩＆等による軌上高の偏位、
あるいは、電車通過時の振動等による振れ角偏位等の発
生が心配される。Contact wires such as overhead contact lines are subject to wear due to constant sliding of current collector shoes, deviation in track height due to loose tension on the contact wire, etc.
Alternatively, there is a concern that deflection angle deviation may occur due to vibrations when a train passes.
そして、これらの要因が重なって、トロリ線の異状摩耗

とも懸念され、トロリ線の保守点検は忽せにはできない
。When these factors combine, there is a concern that abnormal wear of the contact wire may lead to a breakage accident in the worst case.In trains, etc., which transport large numbers of people, there is a concern that this may lead to a catastrophe. Line maintenance and inspection cannot be postponed.
このため、定期的にトロリ線全線に亙ってチェックを行

これらの検査は、電車の運転が休止する深夜間に行なう
必要があるので、人的、作業内容的、時間的に大変な苦
労を伴ううえ、全線にわたって漏れなく検査することは
非常に困難なことであった。Therefore, it is necessary to periodically check the entire contact wire. However, how long is it? It is not easy to conduct manual inspections over long distances, and these inspections must be carried out late at night when train operations are suspended, which is a great effort in terms of personnel, work content, and time. In addition, it was extremely difficult to inspect the entire line without omission.

測される）等を生じ精密な摩耗量の測定は。Therefore, a measuring device (Japanese Patent Publication No. 43-24125 ), but this one is configured so that the measuring roller or pick-up sheave directly contacts the sliding surface of the contact wire, which has a roughened surface (micro-uneven surface) due to the sliding of the current collector. This not only limits the inspection speed and makes the measurement work inefficient, but also
Errors in the measuring roller itself (so-called design tolerances) are added, errors due to wear of the rollers and picker knobs due to long-range measurements, and disembedding errors due to surface roughness of the contact wire sliding surface or grease adhesion. Furthermore, there is an error due to the contact position of the measuring roller or pick-up with the contact wire (if the measuring roller or pick-up always moves in contact with the average wear position of the contact wire, there is no problem, but if the contact wire's sliding surface wears out on one side) If the contact is shifted to either the left or right side, the amount of wear will be measured too much or too little than the actual amount.
困難であった。It was difficult.

望まれていた。In addition, measurements of track height deviation and run-out deviation due to slack in contact wires, etc. are generally carried out roughly, and there is no good way to economically improve the measurement accuracy. In addition, there was a strong desire to develop a measuring device with good measurement accuracy.
本発明は、このような要望に応えるべく開発したもので
ある。The present invention was developed in response to such demands.

In FIG. 1, the rope 17 is loosened and the reference roller frame 12 is
．． 15 is applied to the contact wire 5 by the force of the support spring 15,
The reference roller 9 and the guide row 210 are brought into contact with each other from the lower stage. Note that the measuring vehicle was run in the direction of arrow P shown in FIG.

Therefore, both arcuate surfaces 5 of the trolley non-sliding surface of the trolley ts5
01. ! +01 and rotates to move the reference row 2 frame 12 always keeping a constant distance from the contact wire 3. This is because the arcuate surfaces 501 and 301 on both sides of the contact wire 60 do not wear out and maintain a constant diameter because the contact wire 60 does not slide. This is because the axes of the contact wire 5 and the reference roller 9 always maintain a constant distance from each other due to the reference row 29.

、その変化量を読＆取る。Next, when the reference roller frame 12 moves along the contact wire 6 and reaches a place where the contact wire 6 is worn, the separation distance between the non-contact displacement sensor 2 and the contact sliding surface of the contact wire 6 is determined. changes according to the amount of wear, and the non-contact displacement sensor 2 reads and reads the amount of change.

゛屈流損を発生する。For example, when an eddy current detection type non-contact displacement sensor is used as the non-contact displacement sensor 2, when high-frequency oscillation is applied to the non-contact displacement sensor 2 by a high-frequency oscillator, a high-frequency magnetic field is generated, and the non-contact displacement Eddy currents flow in the metal near the sensor 2, that is, the contact wire 6, in a direction perpendicular to the passage of the magnetic flux, causing eddy current loss.

曲線となる。This eddy current loss increases as the distance between the contact wire 5 and the non-contact displacement sensor 2 approaches, and the oscillation amplitude gradually decreases. The relationship between the separation distance and the oscillation amplitude is a curve close to direct proportion.

に演算記録せしむるものである。Detecting and linearizing this high frequency oscillation, it is taken as a voltage proportional to the distance, and is taken as a change in the separation distance between the contact wire 6 and the non-contact displacement cell 2, that is, a change in the amount of wear on the contact wire 6, The amount of wear is continuously measured and the calculations are recorded on a self-recording measurement recorder.
本発明は上記のように、トロリ線５の摩耗量を非接触で
測定記録するため、非接触型変位センサ２は摩耗するこ
となく、長期間の使用にもよく耐え、摩耗等による誤差
を生ずることがない。As described above, the present invention measures and records the wear amount of the contact wire 5 in a non-contact manner, so the non-contact displacement sensor 2 does not wear out and can withstand long-term use without causing errors due to wear etc. Never.

測定ができる。Next, since the wear amount of the contact wire is measured by the amount of change in the eddy current loss of the contact wire 3 caused by the high-frequency oscillation of the non-contact displacement sensor 2, even if the contact wire 3 is worn out on one side, the average separation Since it is measured as a distance, there is no error caused by the contact position unlike a contact type displacement sensor. Additionally, since it is non-contact, it can perform faster measurements than a contact type sensor. Furthermore, even if the surface of the contact wire 30 is rough, the non-contact displacement sensor 2 will not jump, and the amount of wear can be measured with high accuracy.

である。Next, for example, an encoder or a rotary scale is provided for the elevation angle deviation and deflection angle deviation of the contact wire 3 by directly connecting or communicating with the vertical movement shaft 4 of the base of the measuring arm 10 and the mounting rotation pedestal shaft 6, respectively. As a pulse signal with a deviation of
Since the data is transmitted to a self-recording measurement recorder, highly accurate measurement values can be obtained because the encoder and rotation scale have a resolution of several thousand pulses/rotation.

The pulse signals transmitted from the encoder are counted, these are operationally amplified, and the self-recording recorders of the required elements are recorded together with the traveling position, and the amount of wear at each position of the contact wire, the amount of track height deviation, This allows the amount of deflection angle deviation from the track to be continuously recorded.

ロリ線検測装置A non-contact displacement sensor for detecting wear on the contact wire is installed at the tip of the measurement arm, which is installed on the measurement vehicle so that it can rotate up and down and left and right, so as to always maintain a constant distance from the contact wire. A sensor for measuring the elevation angle is connected to the vertical movement shaft of the base of the vehicle, and a sensor for measuring the deflection angle is connected to the rotating pedestal shaft for mounting the measurement arm. A contact wire inspection device characterized in that the track height deviation of the line and the deflection angle deviation of the contact wire relative to the track are simultaneously and continuously recorded using a self-recording sickle meter.
