Description

本発明は、鉄道構造物のプラットホームの高さ及び離れを計測する計測器及びその計測方法に関する。 The present invention relates to a measuring instrument for measuring the height and separation of a platform of a railway structure and a measuring method thereof.

鉄道構造物について、安全な輸送及び安定的な輸送の確保を図るために、「鉄道に関する技術上の基準を定める省令」は、鉄道の建築限界の基準を規定している。この基準に基づいて鉄道構造物であるプラットホームの高さ及び離れの距離が管理されている。鉄道の事業主は、この計測で検出した危険箇所について補修工事を行い、利用者の安全を確保するように努めている。 In order to ensure safe and stable transportation of railway structures, the “Ministerial Ordinance for Establishing Technical Standards for Railways” stipulates standards for railway building limits. Based on this standard, the height and distance of the platform, which is a railway structure, is managed. Railway employers are working to ensure the safety of users by performing repair work on the dangerous areas detected by this measurement.

ホームの離れ及びホームの高さの計測方法については、通常、ホームの離れはＧＬ（地面）と水平に計測し、ホームの高さは左右のレールそれぞれの中心点を結ぶ直線に対して直角となる垂線を計測する。 Regarding the method of measuring the separation of the home and the height of the home, the separation of the home is usually measured horizontally with the GL (ground), and the height of the home is perpendicular to the straight line connecting the center points of the left and right rails. Measure the perpendicular.

従来、簡易な計測方法として、図５に示すような、直角定規を使用した計測方法が行われてきた。この直角定規を使用した場合の計測方法を図６に示す。図６は、ホームの離れ及びホームの高さの計測方法を示した図である。ホームの離れ及びホームの高さの計測方法は、直角定規を使用する場合、ＧＬ（地面）と水平に計測する必要がり、内側のレール（二本のレールの内のホーム側のレール）に直角定規を乗せて計測する。 Conventionally, as a simple measurement method, a measurement method using a right angle ruler as shown in FIG. 5 has been performed. FIG. 6 shows a measurement method when this right angle ruler is used. FIG. 6 is a diagram illustrating a method of measuring the separation of the home and the height of the home. When using a right-angle ruler, the method of measuring the distance between the home and the home must be measured horizontally with the GL (ground), and is perpendicular to the inner rail (the rail on the home side of the two rails). Measure with a ruler.

また、レーザ、ミリ波等を用いてプラットホームから非接触式で鉄道における建築限界を計測する方法及び装置が既に公知となっている。特許文献１では、プラットホームの端面にレーザ、ミリ波等を利用した非接触式の計測器の基盤をレールと平行に配設し、この位置で計測器を回動させてレールまでの距離と角度を検知すると共に、同様にして計測対象物までの距離と角度を検知する装置が公開されている。距離と角度は、レーザ、ミリ波等を計測対象物へ照射し、その反射波から計測対象物までの距離とそのときの角度を計測するものである。 In addition, a method and an apparatus for measuring a building limit in a railway in a non-contact manner from a platform using a laser, a millimeter wave or the like are already known. In Patent Document 1, a base of a non-contact type measuring instrument using laser, millimeter wave, or the like is disposed on the end face of the platform in parallel with the rail, and the distance and angle to the rail are rotated by rotating the measuring instrument at this position. A device for detecting the distance and the angle to the measurement object in the same manner is disclosed. The distance and angle are used to irradiate a measurement target with a laser, millimeter wave, or the like, and measure the distance from the reflected wave to the measurement target and the angle at that time.

また、特許文献２では、レーザ変位計の計測位置を上下方向に移動させて、レーザ変位計が計測可能位置と計測不可能位置との境界を検出し、この境界をプラットホームの高さとして計測し、レーザ変位計の下方に別のレーザ変位計を設け、このもう一つのレーザ変位計によりホーム離れを計測する方法が公開されている。図８は、従来のレーザを使用したプラットホーム計測装置の構成を示すブロック図である。 In Patent Document 2, the measurement position of the laser displacement meter is moved in the vertical direction, the laser displacement meter detects the boundary between the measurable position and the unmeasurable position, and this boundary is measured as the height of the platform. A method of providing another laser displacement meter below the laser displacement meter and measuring the distance from the home using this another laser displacement meter is disclosed. FIG. 8 is a block diagram showing a configuration of a platform measuring apparatus using a conventional laser.

従来の直角定規を使用した計測方法は、Ｌ型（直角）の定規であったため、幅、高さともに大きいなものとなり、持ち運びの不便があった。また、計測するために水準と水平を出す必要があり、水平レベル調整等の調整作業が多く、手間取るという欠点があった。さらに、定規の置き方、スケールの読み取りにより計測者により誤差が生じることが多かった。またさらに、カントのある場所では定規がホームの下部に接触することによりホームの高さを計測することができないこともあった。 The conventional measuring method using a right-angle ruler is an L-type (right-angle) ruler, so that both the width and the height are large, which is inconvenient to carry. In addition, it is necessary to set the level and level for measurement, and there are many adjustment operations such as horizontal level adjustment. In addition, there were many cases in which an error was caused by the measurer by placing the ruler and reading the scale. Furthermore, the height of the home may not be measured when the ruler touches the lower part of the home at a place where the cant is present.

次に、レーザ、ミリ波等を用いてプラットホームから非接触で鉄道における建築限界を計測する方法及び装置は、人が線路内に立ち入ることなく計測することが可能であるものの、装置が高価であるといった欠点があった。 Next, the method and apparatus for measuring the building limit in a railway without contact from the platform using a laser, millimeter wave, etc. can be measured without a person entering the track, but the apparatus is expensive. There was a drawback.

そこで、本発明は、簡易、迅速、安価に鉄道構造物のプラットホームの高さおよび離れを計測するプラットホーム計測器およびプラットホーム計測方法を提供することを課題としている。 Then, this invention makes it the subject to provide the platform measuring device and platform measuring method which measure the height and the separation | separation of the platform of a railway structure simply, quickly, and cheaply.

以下、図面を参照して本発明の望ましい実施形態を詳細に説明する。但し、本発明は多くの異なる態様で実施することが可能であり、以下に示す実施の形態の記載内容に限定して解釈されるものではない。 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention can be implemented in many different modes and should not be construed as being limited to the description of the embodiments described below.

図１乃至図４は、本発明に係る計測器の一例を示すものである。本発明の計測器は、図１に示すように棒１０４を中心として構成されている。プラットホームの高さ１１４及びプラットホームの離れ１１５の計測は、プラットホーム端１２２から内側レール頭面中心１３６までの長さ及び棒１０４とプラットホーム端の垂直線１２４との傾斜角度αから三角関数により算出する方法により行われる。 1 to 4 show an example of a measuring instrument according to the present invention. The measuring instrument of the present invention is configured around a rod 104 as shown in FIG. The measurement of the platform height 114 and the platform separation 115 is calculated by a trigonometric function from the length from the platform end 122 to the inner rail head surface center 136 and the inclination angle α between the bar 104 and the vertical line 124 of the platform end. Is done.

図１は、本発明の一実施例の計測器を示す全体の構成図であり、図２は、プラットホーム端と同箇所に設置される第１のＬ型部材１０３を示した図であり、図３は、内側レールに設置するレール取付け用部材１３０を示した図であり、図４は、棒１０４上部に取り付けられたゲージ１０１及び傾斜計１０２を示した図である。 FIG. 1 is an overall configuration diagram showing a measuring instrument according to an embodiment of the present invention, and FIG. 2 is a diagram showing a first L-shaped member 103 installed at the same location as a platform end. 3 is a view showing a rail mounting member 130 installed on the inner rail, and FIG. 4 is a view showing a gauge 101 and an inclinometer 102 attached to the upper portion of the bar 104.

プラットホーム１２０に設置する第１のＬ型部材１０３について、図２を用いて説明する。図２に示すように、プラットホームの先端は、通常鈍角になっている。ホームの離れの計測は、プラットホーム凸部１２１が測定基準点となる。他方、ホームの高さの計測は、プラットホーム上面部１２３が測定基準点となる。そこで、第１のＬ型部材１０３を用いることによって、プラットホーム凸部１２１の地面に対して垂直方向線上とプラットホーム上面部１２３の地面に対して水平方向線上との交点となるプラットホーム端１２２を得る。 The 1st L-shaped member 103 installed in the platform 120 is demonstrated using FIG. As shown in FIG. 2, the tip of the platform is usually obtuse. For the measurement of the separation of the home, the platform convex portion 121 serves as a measurement reference point. On the other hand, when measuring the height of the platform, the platform upper surface portion 123 serves as a measurement reference point. Therefore, by using the first L-shaped member 103, a platform end 122 is obtained which is an intersection of a vertical line with respect to the ground of the platform convex part 121 and a horizontal line with respect to the ground of the platform upper surface part 123.

第１のＬ型部材１０３は、垂直方向に厚みＢと水平方向に厚みＡを有しているため、第１のＬ型部材１０３とゲージ１０１とが接触する接点１１７は、プラットホーム端１２２との間に高さＢ及び幅Ａのオフセットが生じることとなる。そこで、これらＢ及びＡをオフセットとして扱う。そして、このＢ及びＡのオフセットに対応して棒１０４の下部に取り付けられるレール用取付け部材１３０にも同様の高さＢと幅Ａのオフセットを設ける。 Since the first L-shaped member 103 has a thickness B in the vertical direction and a thickness A in the horizontal direction, the contact 117 where the first L-shaped member 103 and the gauge 101 come into contact with the platform end 122. An offset of height B and width A occurs between them. Therefore, these B and A are treated as offsets. Then, a similar offset of height B and width A is also provided on the rail attachment member 130 attached to the lower portion of the bar 104 corresponding to the offset of B and A.

図３に示すように、棒１０４の下部には、内側レールに設置するためのレール取付け用部材１３０が取り付けられている。このレール取付け用部材１３０は、棒１０４を取付け固定する棒取付け部材１３１と、棒取付け部材１３１を回転自在にするための軸１３２及び軸受け部材１３３と、さらに、第２のＬ型部材１３４とから構成される。 As shown in FIG. 3, a rail attachment member 130 for installation on the inner rail is attached to the lower portion of the bar 104. The rail mounting member 130 includes a bar mounting member 131 for mounting and fixing the bar 104, a shaft 132 and a bearing member 133 for making the bar mounting member 131 rotatable, and a second L-shaped member 134. Composed.

前記第１のＬ型部材１０３の水平方向の厚みＡと、内側レール頭面中心１３６から前記軸１３２の中心までの水平方向の距離Ａが一致するように、軸受け部材１３３及び棒取付け部材１３１を形成する。 The bearing member 133 and the rod mounting member 131 are arranged so that the horizontal thickness A of the first L-shaped member 103 and the horizontal distance A from the inner rail head surface center 136 to the center of the shaft 132 coincide with each other. Form.

また、前記第１のＬ型部材１０３の垂直方向の厚みＢと、内側レール頭面中心１３６から前記軸１３２の中心までの垂直方向の距離Ｂが一致するように、軸受け部材１３３及び第２のＬ型部材１３４を形成する。 Further, the bearing member 133 and the second L are arranged so that the vertical thickness B of the first L-shaped member 103 coincides with the vertical distance B from the inner rail head surface center 136 to the center of the shaft 132. An L-shaped member 134 is formed.

次に、図４に示すように、棒１０４の上部には、棒の長さを示す目盛り１０６を有するゲージ１０１と、棒の傾斜角度を示す傾斜計１０２とが取り付けられている。傾斜計１０２とゲージ１０１とは、傾斜計取付け板１０５によって一定の傾斜角度βを保ち固定されている。 Next, as shown in FIG. 4, a gauge 101 having a scale 106 indicating the length of the bar and an inclinometer 102 indicating the tilt angle of the bar are attached to the upper part of the bar 104. The inclinometer 102 and the gauge 101 are fixed by an inclinometer mounting plate 105 while maintaining a constant inclination angle β.

傾斜計１０２は、一般に市販されている傾斜計でよい。ゲージ１０１に付された目盛り１０６は、軸１３２の中心からの長さを示すように付されている。接点１１７と接する目盛り１０６の値が棒計測距離１１６（Ｌ）となるように、ゲージ１０１の接触面１４１と棒の側面１４２との間のオフセット距離Ｃを考慮しなければならない。このオフセット距離Ｃの誤差を無くすために、図３に示すように、軸１３２の中心から棒１０４の側面１４２までの距離をオフセット距離Ｃと同一になるように棒受け部材１３１の棒を取り付ける部分を加工する。 The inclinometer 102 may be a commercially available inclinometer. The scale 106 attached to the gauge 101 is attached so as to indicate the length from the center of the shaft 132. The offset distance C between the contact surface 141 of the gauge 101 and the side surface 142 of the bar must be considered so that the value of the scale 106 in contact with the contact 117 becomes the bar measurement distance 116 (L). In order to eliminate the error of the offset distance C, as shown in FIG. 3, a portion to which the rod of the rod receiving member 131 is attached so that the distance from the center of the shaft 132 to the side surface 142 of the rod 104 is equal to the offset distance C. Is processed.

図１に示すように、棒１０４とプラットホーム端の垂直線１２４との傾斜角度αは、前記傾斜計１０２とゲージ１０１との傾斜角度βから傾斜計１０２が示す傾斜計角度γを控除した角度となる（α＝β−γ）。ここで、プラットホーム端１２２から内側レール上部中心１３６までの長さ棒計測距離１１６をＬとする。そうすると、ホームの高さ１１４はＬｃｏｓαとなり、ホームの離れはＬｓｉｎα＋固定値（標準の軌間の１／２＋スラック（Ｓｌａｃｋ：レール軌道の曲線部分における拡張幅））となる。 As shown in FIG. 1, the inclination angle α between the bar 104 and the vertical line 124 at the platform end is obtained by subtracting the inclinometer angle γ indicated by the inclinometer 102 from the inclination angle β between the inclinometer 102 and the gauge 101. (Α = β−γ). Here, the length measuring distance 116 from the platform end 122 to the inner rail upper center 136 is L. Then, the height 114 of the home is Lcos α, and the separation of the home is L sin α + fixed value (1/2 of the standard gauge + slack (Sack: expansion width in the curved portion of the rail track)).

以上のように、第１のＬ型部材を用いて、第１のＬ型部材１０３の垂直方向の厚みＢと水平方向の厚みＡに対応するオフセット距離をレール取付け部材１３０にも設けることにより、プラットホーム端１２２から内側レール頭面中心１３６までの長さ及び棒１０４とプラットホーム端の垂直線１２４との傾斜角度αから三角関数によりホームの高さ及びホームの離れを計測することが可能となる。 As described above, by using the first L-shaped member, by providing the rail mounting member 130 with an offset distance corresponding to the vertical thickness B and the horizontal thickness A of the first L-shaped member 103, From the length from the platform end 122 to the inner rail head surface center 136 and the inclination angle α between the bar 104 and the vertical line 124 of the platform end, the height of the home and the separation of the home can be measured by a trigonometric function.

以上に述べた傾斜計１０２は、重力加速度の方向を検出したり、あるいは重力加速度の傾斜方向成分を検出することにより、傾斜角度を得る方式ものである。 The inclinometer 102 described above is a method for obtaining a tilt angle by detecting the direction of gravitational acceleration or by detecting the tilt direction component of gravitational acceleration.

これに対し、ロータリーエンコーダを用いる方式であっても良い。ロータリーエンコーダは、回転物体の回転量や回転方向等の回転情報を得る計測器である。図８は、傾斜角度の計測にロータリーエンコーダを用いた場合のロータリーエンコーダ取付け部分を示した図である。軸１３２にロータリーエンコーダ１８１を取り付ける。この軸１３２の回転量から棒１０４が傾斜した角度を割り出す。ロータリーエンコーダ１８１が計測する傾斜角度の基準となる基準線は、棒１０４が地面に対して垂直となった時の軸１３２の垂直線１８３とする。この垂直線１８３から、棒をホーム端に向けて倒したときの軸の回転量から、傾斜角度を計測する。図８では傾斜角度表示部１８２を棒取付け部材１３１と棒１０４の下部に取付けてあるが、ロータリーエンコーダのケーブル１８４に長いものを用いれば、棒の上部に取り付けることもできる。 On the other hand, a method using a rotary encoder may be used. The rotary encoder is a measuring instrument that obtains rotation information such as a rotation amount and a rotation direction of a rotating object. FIG. 8 is a diagram showing a rotary encoder mounting portion when a rotary encoder is used for measuring the tilt angle. A rotary encoder 181 is attached to the shaft 132. The angle at which the bar 104 is inclined is determined from the rotation amount of the shaft 132. A reference line serving as a reference for the inclination angle measured by the rotary encoder 181 is a vertical line 183 of the shaft 132 when the bar 104 is perpendicular to the ground. From this vertical line 183, the tilt angle is measured from the amount of rotation of the shaft when the bar is tilted toward the home end. In FIG. 8, the tilt angle display portion 182 is attached to the lower portion of the rod attachment member 131 and the rod 104. However, if a long cable is used for the rotary encoder cable 184, it can be attached to the upper portion of the rod.

なお、図示しないが、ゲージ１０１の表示は電子的に表示されるものでよい。また、プラットホーム端に設置する第１のＬ型部材は、予め棒１０４と一体として形成してあってもよい。さらに、図１に示す実施例では、前記棒１０４に前記目盛り１０６を有するゲージ１０１を取り付け固定する方法が採られているが、予め一体として形成してあってもよい。 Although not shown, the gauge 101 may be displayed electronically. Further, the first L-shaped member installed at the platform end may be formed integrally with the rod 104 in advance. Further, in the embodiment shown in FIG. 1, a method of attaching and fixing the gauge 101 having the scale 106 to the rod 104 is adopted, but it may be formed integrally in advance.
