ところで、軌道走行台車Ｚは、レールや枕木等を運搬する鉄製トロッコや、各種保守点検用の台車であり、図１〜図３に示すように、車体10には、左右一対の前車輪11, 11と左右一対の後車輪12, 12が設けられる。13は前車軸、14は後車軸である。   By the way, the track traveling carriage Z is a steel trolley that transports rails, sleepers, etc., or a truck for various maintenance inspections. As shown in FIGS. 1 to 3, the vehicle body 10 includes a pair of left and right front wheels 11, 11 and a pair of left and right rear wheels 12, 12 are provided. 13 is a front axle, and 14 is a rear axle.

上記前車輪11, 11の各々は、第１基枠１に設けられた前駆動ローラ15と前従動ローラ16にて回転自在に支持される。つまり、前駆動ローラ15と前従動ローラ16は、軸受19, 19にて、第１基枠１に枢支される。そして、左右一対の前駆動ローラ15, 15を第１駆動装置21にて回転駆動する。この第１駆動装置21は第１基枠１に設けられる。
また、上記後車輪12, 12の各々は、第２基枠２に設けられた後駆動ローラ17と後従動ローラ18にて回転自在に支持される。つまり、後駆動ローラ17と後従動ローラ18は、軸受19, 19にて、第２基枠２に枢支される。そして、左右一対の後駆動ローラ17, 17を第２駆動装置22にて回転駆動する。この第２駆動装置22は第２基枠２に設けられる。 Each of the front wheels 11, 11 is rotatably supported by a front drive roller 15 and a front driven roller 16 provided on the first base frame 1. That is, the front driving roller 15 and the front driven roller 16 are pivotally supported on the first base frame 1 by the bearings 19 and 19. Then, the pair of left and right front drive rollers 15 and 15 are rotationally driven by the first drive device 21. The first driving device 21 is provided on the first base frame 1.
Each of the rear wheels 12 and 12 is rotatably supported by a rear drive roller 17 and a rear driven roller 18 provided on the second base frame 2.

Then, the pair of left and right rear drive rollers 17, 17 are rotationally driven by the second drive device 22. The second driving device 22 is provided on the second base frame 2.

また、前駆動ローラ15と後駆動ローラ17は、図１〜図８では、特に斜線にて示すようにウレタン層Ｕを有する。つまり、図９に示すように、所定厚さのウレタンを被覆してウレタン層Ｕを形成する。なお、全てのローラ15, 16, 17, 18を、同様の、ウレタン層Ｕを有する構成とするのが望ましい。   Further, the front drive roller 15 and the rear drive roller 17 have a urethane layer U as shown in particular by hatching in FIGS. That is, as shown in FIG. 9, a urethane layer U is formed by covering urethane with a predetermined thickness. It is desirable that all the rollers 15, 16, 17, and 18 have the same urethane layer U.

第１駆動装置21は、図例では、油圧モータ24と、クラッチ装置25と、該油圧モータ24の出力軸と該クラッチ装置25の入力軸とを連動連結する鎖車・チェイン機構26と、左右の前駆動ローラ15, 15を連結する連動軸27と、この連動軸27と上記クラッチ装置25の出力軸とを連動連結する鎖車・チェイン機構28等から、構成される。
また、第２駆動装置22は、油圧モータ34と、クラッチ装置35と、該油圧モータ34の出力軸と該クラッチ装置35の入力軸とを連動連結する鎖車・チェイン機構36と、左右の後駆動ローラ17, 17を連結する連動軸37と、この連動軸37とクラッチ装置35の出力軸とを連動連結する鎖車・チェイン機構38等から、構成される。 In the illustrated example, the first driving device 21 includes a hydraulic motor 24, a clutch device 25, a chain wheel / chain mechanism 26 that interlocks and connects the output shaft of the hydraulic motor 24 and the input shaft of the clutch device 25, The front drive rollers 15 and 15 are coupled to each other, and an interlocking shaft 27 is coupled to the output shaft of the clutch device 25.

An interlocking shaft 37 for connecting the driving rollers 17 and 17 and a chain wheel / chain mechanism 38 for interlockingly connecting the interlocking shaft 37 and the output shaft of the clutch device 35 are configured.

上述のように、台車Ｚの左右の前車輪11, 11を、各々、前駆動ローラ15と前従動ローラ16にて回転自在に支持し、かつ、上記台車Ｚの後車輪12, 12を、各々、後駆動ローラ17と後従動ローラ18にて回転自在に支持する。しかも、前車輪11と後車輪12を相互に逆回転方向（図１中の矢印Ｒ1 と矢印Ｒ2 参照）に、回転させる。従って、前方の連動軸27と後方の連動軸37とは、矢印Ｒ1 ′と矢印Ｒ2 ′のように、逆方向に回転し、前駆動ローラ15と後駆動ローラ17も逆方向に回転する。
このようにして、台車Ｚが前後方向Ｅに走行する前輪駆動力と後輪駆動力とが相殺（キャンセル）される。故に、小さな拘束力にて、台車Ｚを試験装置に保持すれば十分である。 As described above, the left and right front wheels 11, 11 of the carriage Z are rotatably supported by the front driving roller 15 and the front driven roller 16, respectively, and the rear wheels 12, 12 of the carriage Z are respectively The rear drive roller 17 and the rear driven roller 18 are rotatably supported. In addition, the front wheels 11 and the rear wheels 12 are rotated in opposite directions (see arrows R 1 and R 2 in FIG. 1). Accordingly, the front interlocking shaft 27 and the rear interlocking shaft 37 rotate in opposite directions as indicated by arrows R 1 ′ and R 2 ′, and the front driving roller 15 and the rear driving roller 17 also rotate in the opposite direction. .
In this way, the front wheel driving force and the rear wheel driving force with which the carriage Z travels in the front-rear direction E are canceled (cancelled). Therefore, it is sufficient to hold the carriage Z in the test apparatus with a small restraining force.

そして、図３に於て、30は、前車輪11, 11・後車輪12, 12の各々に対応する軸箱であり、この軸箱30は具体的には、前車軸13の両端、及び、後車軸14の両端を台車Ｚの下部に枢着するものである。このような軸箱30の温度を検出する被接触温度センサＨを、本発明に係る走行試験装置Ｓが具備している。   In FIG. 3, 30 is a shaft box corresponding to each of the front wheels 11, 11 and the rear wheels 12, 12, and specifically, the shaft box 30 includes both ends of the front axle 13, and Both ends of the rear axle 14 are pivotally attached to the lower part of the carriage Z. The traveling test apparatus S according to the present invention includes the contact temperature sensor H that detects the temperature of the axle box 30.

具体的には、共通ベース台５のやや高所に形成した左右の縦枠材７に、前後方向Ｅの長孔31, 31, 31, 31を、貫設し、この縦枠31の各長孔31に沿って上記温度センサＨを、前後方向Ｅに移動可能として、ベース台５に固着している。
即ち、（既述の如く、）第１基枠１と第２基枠２が相互間増減調整のために、該第１・第２基枠１，２をベース台５上を移動させるのに伴って、非接触温度センサＨの配設位置を前後方向Ｅに移動可能としてベース台５に固着している。このように、上記長孔31が重要な役目を果たす。そして、図１と図３のように、載置した台車Ｚの各軸箱30の真下に対応するように、温度センサＨを固定できる。 Specifically, long holes 31, 31, 31, 31 in the front-rear direction E are provided through the left and right vertical frame members 7 formed at a slightly high position of the common base 5, and each length of the vertical frame 31 is extended. The temperature sensor H is fixed to the base 5 so as to be movable in the front-rear direction E along the hole 31.
That is, as described above, the first and second base frames 1 and 2 are used to move the first and second base frames 1 and 2 on the base 5 in order to adjust the mutual increase / decrease. Along with this, the arrangement position of the non-contact temperature sensor H is fixed to the base table 5 so as to be movable in the front-rear direction E. Thus, the long hole 31 plays an important role. And the temperature sensor H can be fixed so that it may correspond to each axle box 30 of the trolley | bogie Z mounted as FIG. 1 and FIG.

次に、図９に於て、ウレタン層Ｕを被覆形成してなるローラ15, 17（及びローラ16, 18）と、車輪11, 12との位置関係を説明すると、車輪11, 12のテーパ状踏み面32の幅寸法Ｗ32に対して、ローラ15, 16, 17, 18の幅寸法Ｗ0 は55％〜80％に設定し、望ましくは、60％〜75％に設定して、余裕代Ｇ1 ，Ｇ2 を十分に取るのが好ましい。なお、Ｇ3 ，Ｇ4 は、クランプロック39による調整代を示す。 Next, with reference to FIG. 9, the positional relationship between the rollers 11, 17 (and the rollers 16, 18) formed by covering the urethane layer U and the wheels 11, 12 will be described. the width dimension W 32 of the tread 32, the width W 0 of the roller 15, 16, 17, 18 is set at 55% to 80%, preferably, set at 60% to 75%, margin It is preferable to take G 1 and G 2 sufficiently. G 3 and G 4 indicate the adjustment allowance by the clamp lock 39.

また、40はエンコーダであり、走行距離を計測し、このエンコーダ40によって計測された所定の走行距離毎に、温度センサＨによって軸箱30の温度を計測して、記録をとることができる。
なお、ロードセルを配設して、各車輪11, 11, 12, 12の荷重を計測するのも好ましい。つまり、軸重測定が容易に行い得る。 Reference numeral 40 denotes an encoder, which can measure a travel distance, measure the temperature of the axle box 30 by the temperature sensor H for each predetermined travel distance measured by the encoder 40, and take a record.
It is also preferable to arrange a load cell and measure the load on each of the wheels 11, 11, 12, and 12. That is, axial load measurement can be easily performed.

定期的に、この種の軌道走行台車Ｚの軸箱30は分解・点検・再組立てされるが、このようなオーバーホールの後に、内部の軸受の組立状態を、本装置の上記温度センサＨにて軸箱30の表面温度を計測して、第１・第２駆動装置21，22による回転に伴って、正常な温度域内か、否かを、容易に、定位置にて、実測できる。なお、ブレーキシュー41等についても、目視にて正常に作動するか否かをチェックすることも容易に行い得る。   Periodically, the axle box 30 of this type of track carriage Z is disassembled, inspected, and reassembled. After such an overhaul, the assembly state of the internal bearing is determined by the temperature sensor H of the apparatus. By measuring the surface temperature of the axle box 30, it is possible to easily measure at a fixed position whether or not the temperature is within a normal temperature range as the first and second drive devices 21 and 22 rotate. Note that the brake shoe 41 and the like can also be easily checked for visual operation.

本発明は、以上説明したように、軌道走行台車Ｚの左右一対の前車輪11, 11を、各々、前駆動ローラ15と前従動ローラ16にて回転自在に支持し、かつ、該前駆動ローラ15と前従動ローラ16を第１基枠１に枢着すると共に一対の上記前駆動ローラ15, 15を回転駆動する第１駆動装置21を上記第１基枠１に設け、上記台車Ｚの左右一対の後車輪12, 12を、各々、後駆動ローラ17と後従動ローラ18にて回転自在に支持し、かつ、該後駆動ローラ17と後従動ローラ18を第２基枠２に枢着すると共に一対の上記後駆動ローラ17, 17を回転駆動する第２駆動装置22を上記第２基枠２に設け、上記第１基枠１と第２基枠２を、相互間隔増減調整可能として、共通ベース台５上に固着したので、台車Ｚ毎に軸距が大小相違しても、簡単に対応できて、安全かつ迅速に走行試験を行い得る。特に夜間の本線を実際に走行させる従来の多大な負担を軽減できる。   In the present invention, as described above, the pair of left and right front wheels 11, 11 of the track traveling carriage Z are rotatably supported by the front drive roller 15 and the front driven roller 16, respectively, and the front drive roller 15 and a front driven roller 16 are pivotally attached to the first base frame 1 and a first drive device 21 for rotating the pair of front drive rollers 15 and 15 is provided on the first base frame 1. A pair of rear wheels 12 and 12 are rotatably supported by a rear drive roller 17 and a rear driven roller 18, respectively, and the rear drive roller 17 and the rear driven roller 18 are pivotally attached to the second base frame 2. In addition, a second drive device 22 that rotationally drives the pair of rear drive rollers 17 and 17 is provided in the second base frame 2 so that the first base frame 1 and the second base frame 2 can be adjusted to increase or decrease each other. Because it is fixed on the common base stand 5, even if the axle distance is different for each carriage Z, it can be easily handled, and a safe and quick running test Get done. In particular, it is possible to reduce the conventional burden of actually traveling on the main line at night.

また、軌道走行台車Ｚの左右一対の前車輪11, 11を、各々、前駆動ローラ15と前従動ローラ16にて回転自在に支持し、かつ、上記台車Ｚの左右一対の後車輪12, 12を、各々、後駆動ローラ17と後従動ローラ18にて回転自在に支持し、さらに、上記前車輪11と上記後車輪12を相互に逆回転方向に、回転駆動させるように構成したので、台車Ｚが前後方向Ｅに走り出す力が相互にキャンセルされ、小さな力で、安定して確実に一定位置に拘束できる。   Further, the pair of left and right front wheels 11, 11 of the track carriage Z are rotatably supported by the front driving roller 15 and the front driven roller 16, respectively, and the pair of left and right rear wheels 12, 12 of the carriage Z are supported. Are respectively supported by the rear driving roller 17 and the rear driven roller 18 so as to be rotatable, and further, the front wheel 11 and the rear wheel 12 are driven to rotate in opposite directions to each other. The forces that Z starts to run in the front-rear direction E are canceled each other, and can be stably and reliably restrained to a certain position with a small force.

また、上記前駆動ローラ15・前従動ローラ16・後駆動ローラ17・後従動ローラ18が、外周面側にウレタン層Ｕを有するので、被テスト物としての台車Ｚの各車輪11, 12を傷付けることがない。
また、上記台車Ｚの前車輪11, 11・後車輪12, 12の各々に対応する軸箱30の温度を検出する非接触温度センサＨを設けたことで、最も台車Ｚの試験で重要な軸箱30の再組立状態の正常と異常を、短時間に確実に検知可能となる。
また、上記台車Ｚの前車輪11, 11・後車輪12, 12の各々に対応する軸箱30の温度を検出する非接触温度センサＨを、上記共通ベース台５に配設し、しかも、上記第１基枠１と第２基枠２が上記相互間増減調整のために上記ベース台５上を移動するのに伴って、上記非接触温度センサＨの配設位置を前後方向に移動可能として上記ベース台５に固着した構成としたので、軸距の大小相違する台車Ｚであっても各々の台車Ｚを高精度に、その軸箱30の温度の測定が可能である。 Further, the front drive roller 15, the front driven roller 16, the rear drive roller 17, and the rear driven roller 18 have the urethane layer U on the outer peripheral surface side, so that the wheels 11, 12 of the carriage Z as a test object are damaged. There is nothing.
Further, by providing a non-contact temperature sensor H for detecting the temperature of the axle box 30 corresponding to each of the front wheels 11, 11 and rear wheels 12, 12 of the carriage Z, the most important axis in the examination of the carriage Z is provided. Normality and abnormality of the reassembly state of the box 30 can be reliably detected in a short time.
