Abstract

PURPOSE:To measure a wear amount during traveling all day by providing a detecting part which consists of a detector for detecting the rise amount of a measuring roller to output the detected signal, and a computation processing part which is placed on a railroad maintenance working vehicle and processed the detected signal to calculate the remaining diameter of the trolley wire. CONSTITUTION:A measuring roller which is provided at the middle of two guide rollers 32a, 32b comes into contact with the peripheral surface of a trolley wire 1, so the measuring roller is raised by a height corresponding to the wear amount of the peripheral surface to the guide rollers which come into contact with the particular positions of both side surfaces. The rise amount is detected by a detector while a railroad maintenance working vehicle 4 is traveling, the detected signal is processed by a computation processing part 5 to measure the remaining diameter of the trolley line continuously. Next, for the measurement of the trolley wire where high voltage is applied, a supporting mechanism 6 and the detecting part is high-voltage insulated from the railroad maintenance working vehicle, and the detecting part and the computation processing part are connected with a cable by means of high votage insulation, so it is possible to prevent high voltage from being applied to the supporting mechanism and the computation processing part.

2. Description of the Related Art FIG. 4 shows an outline of an erection structure of an overhead trolley wire (hereinafter simply referred to as a trolley wire) 1. In FIG. 4 (a), a messenger wire 12 is stretched between supporting poles 11 and The trolley wire 1 is laid horizontally using the hanger 13. The height of the trolley line 1 changes depending on the state of the line, and also changes vertically and horizontally due to train operation. While the pantograph 21 provided in the electric vehicle 2 follows the vertical fluctuation, the sliding plate 211 slides into contact with the lower surface (referred to as sliding surface or sliding surface) of the trolley wire to receive electric power, and the vehicle is driven. It This sliding contact causes the sliding surface to gradually wear. However, the sliding plate 211 on the pantograph side also wears in the same way, but in order to avoid intensive wear of the same part,
As shown in (b), the trolley wire is installed so as to be displaced alternately in the left-right direction at right angles to the line, and the displacement width H is, for example, 700 mm.
It is said that. Next, (c) shows the cross section of the trolley wire 1,
Two grooves 1a for the hanger 13 are provided in a circle having a diameter φ. Due to the above wear, the width W of the sliding surface 1b gradually increases and the remaining diameter D changes. When the wear progresses and the residual diameter D reaches the use limit, the strength becomes weak and there is a risk of cutting. Therefore, the residual diameter D is measured and managed in a timely manner, and when the limit is reached, the trolley wire is replaced.

Initially, the remaining diameter D was measured manually by using a micrometer, but this work requires several persons including a measuring person and an observer for approaching a train. In addition, working at heights with a trolley wire several meters high is inefficient and dangerous. In order to improve such work, various optical measuring devices mounted on a measuring vehicle and measuring wear during running have been developed, but these are targeted for main line sections including Shinkansen, It is equipped with a dedicated inspection vehicle and measures while traveling at almost the same high speed as a commercial train. Both are large-scale devices and are quite expensive. Since the above-mentioned various measuring devices are of an optical type, they are of a so-called non-contact type with respect to the trolley wire, and the measurement can be performed regardless of whether or not a high voltage is applied to the trolley wire. ..

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a first embodiment of the present invention (a)
Is a perspective external view of the detection unit, (b) is an explanatory view of the principle of wear measurement of the trolley wire, and FIG. 2 is an overall configuration diagram of the wear measurement device.
In the detection unit 3 of FIG. 1 (a), two guide rollers 32a, 32b that contact the follower base 31 at fixed positions on both side surfaces of the trolley wire 1 are arranged at appropriate intervals, and the two guide rollers are arranged in the middle. Measuring roller that contacts the sliding surface of the trolley wire
33 will be provided. Fixing the central axis 331 of the measuring roller 34
The measuring roller is urged upward by a spring 35 while being pivotally supported. The tip of the central shaft 331 is coupled to the detector 37 via the coupling arm 36. As the detector 37, for example, a rotary encoder is used. In FIG. 1 (b), it is assumed that the sliding surface 1b is worn by the height h. Two guide rollers 32a,
32b contacts a fixed position p on both sides of the trolley wire 1,
On the other hand, since the measuring roller 33 comes into contact with the sliding surface 1b, the measuring roller is elevated by the amount of wear h from the dotted line to the position indicated by the solid line, as compared with when there is no wear. This increase causes the rotary encoder 37 to rotate, and the amount of increase, that is, the amount of wear h, is detected from the rotation angle, and this is subtracted from the diameter φ to calculate the remaining diameter D. Here, the limit of the wear amount that can be measured by this method will be described. The height position of the contact point p changes depending on the size of the illustrated angle θ of the guide roller 32. It needs to be small. However, since there is a limit to the angle θ, there is a limit to the amount of wear that can be measured.
One-third is the maximum limit and is actually less than this.
In FIG. 2, the track maintenance work vehicle 4 is provided with a support mechanism 6, and its fixed base 61 is fixed by a fixing bolt 62. A hinge rotation mechanism 63 is provided for the fixed base, and a movable arm 64 capable of vertical movement and horizontal rotation is attached to this.
The spring 65 urges the movable arm upward. A vertically rotating plate 66 is pivotally supported on the tip of the movable arm, and the detecting unit 3 is attached to this.
Mount and fix. When measuring wear, the spring
The urging force of 65 raises the movable arm 64 to bring both guide rollers 32a and 32b into contact with both side surfaces of the trolley wire. When the track maintenance work vehicle travels at a low speed, angle signals corresponding to the amount of rise of the measurement roller 33 are sequentially detected by the rotary encoder 37, and the detection signal is input to the arithmetic processing unit 5 by the connection cable 38 and processed. The remaining diameter is sequentially calculated as the vehicle travels, and its continuous data is obtained.
