Description

本発明は、パンタグラフを介して電気鉄道へ電力供給するためのトロリ線の摩耗量を算定するトロリ線の摩耗量算定方法およびトロリ線の摩耗量算定装置に関する。   The present invention relates to a trolley wire wear amount calculating method and a trolley wire wear amount calculating apparatus for calculating the wear amount of a trolley wire for supplying electric power to an electric railway via a pantograph.

従来、電気鉄道の架空電車線において、車両への電力供給はトロリ線とパンタグラフとが接触することによって行われている。
図３（ａ）に示すように、トロリ線１０１は、未使用（新品）の状態では、下部側１０１ａが下方に突出するように湾曲している。そして、このトロリ線１０１の下部側１０１ａの湾曲している部分が、パンタグラフとの接触による機械的および電気的な要因によって図３（ｂ）に示すように摩耗するため、トロリ線１０１の摩耗量１０１ｂを定期的に測定し、この摩耗量１０１ｂが一定の値に達した場合には、トロリ線１０１の交換を行っている。
トロリ線１０１の摩耗量１０１ｂを算定する方法としては、トロリ線１０１の摩耗した部分を除いた残存直径１０２や、しゅう面（パンダグラフが当接して摩耗した面）の幅１０３を、検測車に搭載した測定装置や作業員によって測定し、これらの残存直径１０２やしゅう面の幅１０３からトロリ線１０１の摩耗量１０１ｂを算定している（例えば、特許文献１乃至３参照）。 Conventionally, in an overhead railway line of an electric railway, power is supplied to a vehicle by contacting a trolley line and a pantograph.
As shown in FIG. 3A, the trolley wire 101 is curved so that the lower side 101a protrudes downward in an unused (new) state. Since the curved portion of the lower side 101a of the trolley wire 101 is worn as shown in FIG. 3B due to mechanical and electrical factors due to contact with the pantograph, the amount of wear of the trolley wire 101 101b is measured periodically, and when the amount of wear 101b reaches a certain value, the trolley wire 101 is replaced.
As a method of calculating the wear amount 101b of the trolley wire 101, the remaining diameter 102 excluding the worn portion of the trolley wire 101 and the width 103 of the contact surface (the surface worn by the contact with the panda graph) are measured. The wear amount 101b of the trolley wire 101 is calculated from the remaining diameter 102 and the width 103 of the contact surface (see, for example, Patent Documents 1 to 3).

しかしながら、従来のトロリ線の摩耗量算定方法では、トロリ線のしゅう面が平坦であることが前提とされているため、トロリ線のしゅう面が平坦でない場合、摩耗量の算定に誤差が生じることになる。
例えば、しゅう面の中央部が突出するように湾曲している場合、しゅう面の中央部で残存直径を測定して残存面積を算定すると、残存面積が実際よりも大きくなり、摩耗量が少なく算定されることになる。
また、しゅう面を測定する場合、しゅう面が平坦でないとしゅう面を特定できず、正確な摩耗量を算定することができない。 However, the conventional trolley wire wear amount calculation method presupposes that the trolley wire has a flat contact surface, so that if the trolley wire has a non-flat contact surface, an error may occur in the calculation of the wear amount. become.
For example, if the center of the contact surface is curved so that it protrudes, the remaining area is calculated by measuring the remaining diameter at the center of the contact surface. Will be.
Further, when measuring the contact surface, if the contact surface is not flat, the contact surface cannot be specified, and an accurate wear amount cannot be calculated.

そこで、本発明は、トロリ線のしゅう面が平坦でない場合もトロリ線の摩耗量を確実に算定することができるトロリ線の摩耗量算定方法およびトロリ線の摩耗量算定装置を提供することを目的とする。   Accordingly, an object of the present invention is to provide a trolley wire wear amount calculation method and a trolley wire wear amount calculation apparatus capable of reliably calculating the wear amount of the trolley wire even when the contact surface of the trolley wire is not flat. And

以下、本発明の実施形態によるトロリ線の摩耗量算定装置およびトロリ線の摩耗量算定方法について、図１および図２に基づいて説明する。
図１に示すように、本実施形態によるトロリ線の摩耗量算定装置１は、摩耗量１１ｂ（図２参照）を算定する対象となるトロリ線１１の形状を測定する形状測定部２と、形状測定部２で測定されたトロリ線１１の形状からトロリ線１１の摩耗量１１ｂを算定する摩耗量算定部３と、を備えている。 Hereinafter, a trolley wire wear amount calculation apparatus and a trolley wire wear amount calculation method according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2.
As shown in FIG. 1, the trolley wire wear amount calculation apparatus 1 according to the present embodiment includes a shape measuring unit 2 that measures the shape of the trolley wire 11 that is a target for calculating the wear amount 11 b (see FIG. 2), and a shape. A wear amount calculating unit 3 that calculates the wear amount 11b of the trolley wire 11 from the shape of the trolley wire 11 measured by the measuring unit 2;

形状測定部２は、電気鉄道の車両の上部（屋根）に設置されていて、下側からトロリ線１１の下部側１１ａの表面にレーザ光２１をスキャニング照射することで、トロリ線１１の下部側１１ａの形状を測定可能に構成されている。
形状測定部２によるトロリ線１１の下部側１１ａの形状の測定方法としては、例えば、トロリ線１１の下部側１１ａにレーザ光２１を照射し、レーザ光２１の光量（明るさ）から、形状測定部２とトロリ線１１の下部側１１ａとの間の距離を算定してトロリ線１１の下部側１１ａの形状を特定する方法や、トロリ線１１の下部側１１ａにレーザ光２１を照射し、トロリ線１１の下部側１１ａに反射したレーザ光２１が形状測定部２に到達する時間から、形状測定部２とトロリ線１１との間の距離を算定してトロリ線１１の下部側１１ａの形状を特定する方法などが考えられる。
なお、トロリ線１１は、下部側１１ａが摩耗するため、下部側１１ａの形状を測定することで、摩耗した部分の形状を測定することができる。 The shape measuring unit 2 is installed on the upper part (roof) of the electric railway vehicle, and scans the surface of the lower side 11a of the trolley wire 11 from the lower side by scanning the laser light 21, thereby lower side of the trolley wire 11. The shape of 11a can be measured.
As a method for measuring the shape of the lower side 11 a of the trolley wire 11 by the shape measuring unit 2, for example, the lower side 11 a of the trolley wire 11 is irradiated with the laser light 21, and the shape is measured from the light amount (brightness) of the laser light 21. The method of calculating the distance between the part 2 and the lower side 11a of the trolley wire 11 to identify the shape of the lower side 11a of the trolley wire 11, or irradiating the lower side 11a of the trolley wire 11 with the laser light 21 and From the time when the laser beam 21 reflected on the lower side 11a of the line 11 reaches the shape measuring unit 2, the distance between the shape measuring unit 2 and the trolley wire 11 is calculated and the shape of the lower side 11a of the trolley wire 11 is determined. A method of specifying the number can be considered.
In addition, since the lower side 11a wears out the trolley wire 11, the shape of the worn part can be measured by measuring the shape of the lower side 11a.

摩耗量算定部３は、形状測定部２が測定したトロリ線１１の下部側１１ａの形状をもとにトロリ線１１の断面形状を算定し、このトロリ線１１の断面形状と、使用前のトロリ線１２の断面形状とを比較して、摩耗量１１ｂを算定する対象となるトロリ線１１の残存面積１１ｃを算定し、この残存面積１１ｃから摩耗量１１ｂを算定可能に構成されている。
この使用前のトロリ線１２の断面形状は、摩耗量１１ｂを算定する対象となるトロリ線１１の使用前の断面形状と同じものとする。 The wear amount calculating unit 3 calculates the cross-sectional shape of the trolley wire 11 based on the shape of the lower side 11a of the trolley wire 11 measured by the shape measuring unit 2, and the cross-sectional shape of the trolley wire 11 and the trolley before use. The remaining area 11c of the trolley wire 11 to be used for calculating the wear amount 11b is calculated by comparing with the cross-sectional shape of the wire 12, and the wear amount 11b can be calculated from the remaining area 11c.

In addition, the communication unit may be configured to communicate data from the shape measuring unit 2 to the wear amount calculating unit 3, or the shape of the lower side 11 a of the trolley wire 11 measured by the shape measuring unit 2. Data may be input to the wear amount calculation unit 3 manually. The wear amount calculation unit 3 may be provided in the vehicle or may be provided in a place other than the vehicle.

また、レーザ光２１をスキャニング照射してトロリ線１１の下部側１１ａの形状を測定するため、トロリ線１１の下部側１１ａの形状を確実に測定することができ、摩耗量１１ｂを確実に算定することができる。
そして、トロリ線１１の摩耗量１１ｂを確実に算定することができるため、トロリ線の管理を正確に行うことができる。 In the trolley wire wear amount calculation device 1 and the trolley wire wear amount calculation method according to the present embodiment described above, the shape of the lower side 11a of the trolley wire 11 to be used for calculating the wear amount 11b is measured.
