上記従来検測法（Ａ）から（Ｄ）は、以下のような問題を有していた。 The conventional inspection methods (A) to (D) have the following problems.
従来検測法（Ａ）によれば、動的な軌道検測を行うことはできるが、専用車両を用いる必要があるので、任意の鉄道路線あるいは鉄道事業者での軌道検測は、困難であった。 According to the conventional inspection method (A), it is possible to perform dynamic track inspection, but since it is necessary to use a dedicated vehicle, track inspection on any rail line or railway operator is difficult. there were.
従来検測法（Ｂ）によれば、動的な軌道検測を行うことはできるが、軌道検測装置を搭載した車両を用いる必要があるので、任意の鉄道路線あるいは鉄道事業者での軌道検測は、困難であった。 According to the conventional inspection method (B), it is possible to perform dynamic track inspection, but since it is necessary to use a vehicle equipped with a track inspection device, a track on an arbitrary railway line or railway operator The inspection was difficult.
従来検測法（Ｃ）によれば、任意の鉄道路線あるいは鉄道事業者での軌道検測は、比較的容易に行えるが、静的な軌道検測しか行えなかった。すなわち、実際の鉄道車両が走行した際の軌道状態は、把握することができず、しかも、場合によっては、脱線事故等を起こすおそれがあった。 According to the conventional inspection method (C), track inspection on an arbitrary railway line or railway operator can be performed relatively easily, but only static track inspection can be performed.

By mounting the load adding means on a railroad vehicle, dynamic track inspection can be easily performed on any railway line or railway operator, and the load can be adjusted according to the axle load of the railway vehicle traveling on any route. It can be carried out.
また、この発明によれば、荷重付加手段として、所定長さに切断したレール等の重量物を用いることにより、任意の路線を走行する鉄道車両の動的な軌道検測が軸重に応じた荷重で容易に行える。 Further, according to the present invention, by using a heavy object such as a rail cut into a predetermined length as the load applying means, the dynamic track inspection of the railroad vehicle traveling on an arbitrary line is adapted to the axial load.

この発明の軌道検測装置の一実施形態を、図面を参照しながら説明する。 An embodiment of the track inspection device of the present invention will be described with reference to the drawings.
図１は、この発明の軌道検測装置を示す側面図、図２は、この発明のこの発明の軌道検測装置を示す底面図である。 FIG. 1 is a side view showing a track inspection apparatus of the present invention, and FIG. 2 is a bottom view showing the track inspection apparatus of the present invention.
図１および図２に示すように、この発明の軌道検測装置は、軌道および道路上を走行可能な軌陸車１と、軌陸車１に搭載された軌道検測装置本体２とからなっている。なお、この軌道検測装置は、正矢法により軌道検測を行うものであるが、これ以外に、偏心矢法、慣性正矢法、慣性法等により軌道検測を行うものであってもよい。 As shown in FIG. 1 and FIG. 2, the track inspection device of the present invention comprises a railroad vehicle 1 capable of traveling on tracks and roads, and a track inspection device main body 2 mounted on the railroad vehicle 1. .. This orbit inspection device performs orbit inspection by the orthodox method, but in addition to this, it may also perform orbit inspection by the eccentric arrow method, inertia normal arrow method, inertia method, or the like. Good.
軌陸車１は、一般道路走行時には、図１中、実線で示すように、軌道走行車輪３を車体に収納し、この状態で道路走行タイヤ４を使用して走行する。一方、軌道５上を走行する場合は、軌道走行車輪３を、図１中、破線で示すように、軌道５上に下降させる。このように、道路走行タイヤ４は、軌道５から離れ、軌道走行車輪３のみが軌道５と接触するので、軌陸車１は、軌道走行車輪３を駆動することによって、軌道走行を行うことができる。軌道走行の際、軌陸車１を含む全荷重は、軌道５にかかる。
When traveling on a general road, the railroad vehicle 1 stores the
軌道検測装置本体２は、軌道５の幅や高さを測定する二次元レーダセンサ等からなる複数個の測定センサ６と、各測定センサ６によって測定された検測信号を検測結果として自動的に記録し、演算処理する制御部７と、荷重付加手段としての水タンク８とを備えている。
The orbit inspection device main body 2 automatically measures a plurality of
水タンク８は、軌陸車１の荷台に搭載され、水タンク８への水の注排水が自在に行なえ、水タンク８内の水量は、流量計（図示せず）や水タンク８内面に記載された目盛等によって自動的に把握できるようになっている。このように、水タンク８内の水量を調整することによって、任意の路線を走行する鉄道車両の軸重に応じた荷重で動的な軌道検測を容易かつ的確に行うことが可能となる。動的な軌道検測を行うに際にして、水タンク８への水の注排水を検測現場で行なえば、軌陸車１の検測現場への走行および検測現場からの走行が楽に行える。 The water tank 8 is mounted on the bed of the railroad vehicle 1, and water can be freely poured into and discharged from the water tank 8. The amount of water in the water tank 8 is described on a flow meter (not shown) or the inner surface of the water tank 8. It can be automatically grasped by the graduated scale. As described above, by adjusting the amount of water in the water tank 8, it becomes possible to easily and accurately perform the dynamic track inspection with a load according to the axle weight of the railway vehicle traveling on an arbitrary route. When performing dynamic track inspection, if water is poured into and discharged from the water tank 8 at the inspection site, the rail vehicle 1 can easily travel to and from the inspection site. ..
図３（ａ）に示すように、水タンク８内を仕切り壁により複数区画に分割しなかった場合には、軌陸車の加減速時において、水タンク８内の水面が図中点線で示すように上下動し、この結果、前後軸の荷重が変動して、軌道検測に支障を来すが、図３（ｂ）に示すように、水タンク８内を仕切り壁９により複数区画に分割した場合には、軌陸車の加減速時において、各区画内の水面は、図中点線で示すように上下動するが、水面が全体的に上下動する場合に比べて、前後軸の荷重の変動が抑制される結果、軌道検測に支障を来すおそれがない。 As shown in FIG. 3(a), when the water tank 8 is not divided into a plurality of partitions by partition walls, the water surface in the water tank 8 is indicated by the dotted line in the figure during acceleration/deceleration of the railroad vehicle. As a result, the load on the front and rear axes fluctuates, which hinders the orbit inspection. However, as shown in FIG. 3B, the water tank 8 is divided into a plurality of sections by the partition wall 9. In this case, when accelerating and decelerating the railroad vehicle, the water surface in each compartment moves up and down as shown by the dotted line in the figure.However, compared with the case where the water surface moves up and down as a whole, As a result, fluctuations are suppressed, and there is no risk of obstacles to track inspection.
なお、各仕切り壁９に連通孔１０を形成することによって、各区画内における水の移動がある程度、自由になるので、さらに、前後軸の荷重の変動が抑制される。連通孔１０の数は、適宜、選択する。 By forming the communication hole 10 in each partition wall 9, the movement of water in each compartment is free to some extent, so that fluctuations in the load on the front and rear shafts are further suppressed. The number of communication holes 10 is appropriately selected.
荷重付加手段としては、水タンク８以外に、複数個の重量物、例えば、所定長さに切断したレールを用いてもよい。レールは、単位長さ当たりの重量が既知であり、かつ、鉄道業界において容易に入手できる利点がある。また、水タンクのように、前後加速度による重心の移動の心配もない。さらに、所定長さ、例えば、１ｍ程度に切断することによって、比較的容易に軌陸車に乗せることができ、かつ安定する。また、短尺のレールを軌陸車の適切な位置に配置すれば、重量バランスも容易に調整可能である。 In addition to the water tank 8, a plurality of heavy objects, for example, rails cut into a predetermined length may be used as the load applying means. Rails have the advantage of having a known weight per unit length and being readily available in the rail industry. Also, unlike the water tank, there is no need to worry about movement of the center of gravity due to longitudinal acceleration. Furthermore, by cutting it to a predetermined length, for example, about 1 m, it can be mounted on a railroad vehicle with relative ease and is stable. In addition, the weight balance can be easily adjusted by disposing a short rail at an appropriate position on the railroad vehicle.
以上、説明したように、この発明によれば、軌道および道路上を走行可能な軌陸車１に軌道検測装置本体２を搭載して動的な軌道検測を行うに際し、軌道検測装置本体２を荷重付加手段を備えたものとし、荷重付加手段を軌陸車１に搭載することによって、動的な軌道検測を任意の路線あるいは事業者で容易に、しかも、任意の路線を走行する鉄道車両の軸重に応じた荷重で行うことができる。 As described above, according to the present invention, the track inspection device body is mounted when the track inspection device body 2 is mounted on the railroad vehicle 1 capable of traveling on the track and the road to perform the dynamic track inspection. 2 is equipped with a load applying means, and the load applying means is mounted on the railroad vehicle 1, so that the dynamic track inspection can be easily performed on any route or by the operator, and the railway runs on any route. It can be performed with a load according to the axle weight of the vehicle.
また、この発明によれば、荷重付加手段として、所定長さに切断したレールを用いることにより、任意の路線を走行する鉄道車両の動的な軌道検測が軸重に応じた荷重で容易に行える。 Further, according to the present invention, by using a rail cut to a predetermined length as the load applying means, dynamic track inspection of a rail vehicle traveling on an arbitrary route can be easily performed with a load according to the axle load. You can do it.
また、この発明によれば、荷重付加手段として、水の注排水が自在に行なえる水タンク８を用いることにより、動的な軌道検測が任意の路線を走行する鉄道車両の軸重に応じた荷重で容易に行える。 Further, according to the present invention, by using the water tank 8 capable of freely pouring and draining water as the load applying means, the dynamic track inspection can be performed depending on the axle weight of the railway vehicle traveling on an arbitrary route. It can be easily performed with a large load.
また、この発明によれば、水タンク８内を仕切り壁９により複数区画に分割することによって、軌陸車１の加減速時における水タンク８内の水面の上下動による荷重の変動を抑制することができる。 Further, according to the present invention, by dividing the inside of the water tank 8 into a plurality of sections by the partition wall 9, it is possible to suppress the fluctuation of the load due to the vertical movement of the water surface in the water tank 8 during the acceleration/deceleration of the railroad vehicle 1.
