Description
【０００１】[0001]
本考案は、車体に対して９０度ないし１８０度旋回可能な操舵・駆動輪を備え た走行台車に関する。 The present invention relates to a traveling vehicle having steering / driving wheels capable of turning 90 degrees to 180 degrees with respect to a vehicle body.
【０００２】[0002]
走行台車としては例えば図１及び図２に示すものが知られている。 すなわち、車体１の対向隅部にブラケット２を旋回可能にそれぞれ取付け、こ のブラケット２に駆動輪３と走行モータ４を取付けて車体１に対して９０度ない し１８０度旋回可能な操舵・駆動輪とし、前記車体１の他の対向隅部にキャスタ ５をそれぞれ取付け、操舵・駆動輪を旋回することで任意方向に走行できる走行 台車が知られている。 Known traveling vehicles are those shown in FIGS. 1 and 2, for example. That is, the brackets 2 are attached to the opposite corners of the vehicle body 1 so as to be turnable, and the driving wheels 3 and the traveling motors 4 are attached to the brackets 2 so that the vehicle can be turned by 90 degrees or 180 degrees. There is known a traveling carriage that is a wheel and has casters 5 attached to other opposing corners of the vehicle body 1 and can travel in any direction by turning the steering / driving wheels.
【０００３】[0003]
かかる走行台車においては操舵・駆動輪をどの方向に向けても走行モータ４が 車体１より外部に突出しないようにする必要がある。 すなわち、走行モータ４が車体１より外部に突出すると走行時や旋回時に走行 モータ４が障害物あるいは人間と衝突して走行モータ４を破損あるいは人間を傷 つけることがある。特に走行台車を遠隔操作したり、走行モータ４を目視できな い状態で操作する場合には走行モータ４が衝突したことを操作者が知ることがで きず大きな事故になる。 このために、ブラケット２の旋回中心２ａが車体１の外側面１ａより走行モー タ４の長さ以上内側位置となり、駆動輪３間の距離Ｌ1 が車体全長に対して短か くなって車体安定性が悪くなるばかりか、車体の小形化の障害となる。In such a traveling vehicle, it is necessary that the traveling motor 4 does not project to the outside of the vehicle body 1 no matter which direction the steering / driving wheels are directed. That is, when the traveling motor 4 projects outside the vehicle body 1, the traveling motor 4 may collide with an obstacle or a person during traveling or turning, and the traveling motor 4 may be damaged or injured. In particular, when operating the traveling vehicle remotely or operating the traveling motor 4 in a state where the traveling motor 4 cannot be seen, the operator cannot know that the traveling motor 4 has collided, which causes a serious accident. For this reason, the turning center 2a of the bracket 2 is located inside the outer surface 1a of the vehicle body 1 by at least the length of the traveling motor 4, and the distance L 1 between the drive wheels 3 is short with respect to the entire length of the vehicle body. Not only will the stability deteriorate, but it will also hinder the downsizing of the vehicle body.
【０００４】 そこで、本考案は前述の課題を解決できるようにした走行台車を提供すること を目的とする。Therefore, an object of the present invention is to provide a traveling vehicle capable of solving the above-mentioned problems.
【０００５】[0005]
車体１０の隅部に、駆動輪１３と走行モータ１４を備えたブラケット１１を旋 回自在にそれぞれ支承して操舵・駆動輪とし、前記走行モータ１４の車体走行方 向一側面にタッチスイッチ１６を取付けて成る走行台車。 Brackets 11 having drive wheels 13 and a traveling motor 14 are rotatably supported at the corners of the vehicle body 10 to serve as steering and driving wheels, and a touch switch 16 is provided on one side of the traveling motor 14 in the vehicle traveling direction. A traveling trolley that is mounted.
【０００６】[0006]
走行モータ１４が障害物、人間と衝突する以前にタッチスイッチ１６が接して 信号を出力するから、その信号によってその衝突を感知して走行モータ１４と障 害物、人間の衝突を防止する操作ができて走行モータ１４を破損、人間を傷つけ ること防止でき、ブラケット１１の取付け位置を走行モータ１４が車体１０より 外方に突出する位置として駆動輪１３間の距離を車体全長に対して長くし車体安 定性を向上できるし、車体の小型化が可能となる。 The touch switch 16 contacts and outputs a signal before the traveling motor 14 collides with an obstacle or a person. Therefore, the operation can be detected by detecting the collision by the signal to prevent the traveling motor 14 from colliding with an obstacle or a person. As a result, it is possible to prevent the traveling motor 14 from being damaged and injuring human beings, and the mounting position of the bracket 11 is set to a position where the traveling motor 14 projects outward from the vehicle body 10 to increase the distance between the drive wheels 13 with respect to the entire vehicle body length. The stability of the vehicle body can be improved and the vehicle body can be downsized.
【０００７】[0007]
図３、図４に示すように、車体１０の対向隅部にブラケット１１が支軸１２で 旋回自在にそれぞれ支承され、このブラケット１１に駆動輪１３とその駆動輪１ ３を回転駆動する走行モータ１４が取付けられて９０度ないし１８０度旋回可能 な操舵・駆動輪としてある。前記支軸１２はレバーとステアリングシリンダある いはスプロケットとチェーンとステアリングシリンダ等で回転する。 前記車体１０の他の対向隅部にキャスタ１５がそれぞれ取付けてある。 前記走行モータ１４における車体走行方向一側面にタッチスイッチ１６が取付 けてあり、該タッチスイッチ１６は障害物等と接すると信号を出力するものであ って、図５に示すように取付用ばね等の緩衝材１７を介して走行モータ１４に取 付けてある。 As shown in FIGS. 3 and 4, a bracket 11 is rotatably supported by a support shaft 12 at opposite corners of a vehicle body 10, and a drive motor for driving the drive wheel 13 and its drive wheel 13 to rotate on the bracket 11. It is a steering / drive wheel that can be turned by 90 ° to 180 ° with 14 attached. The support shaft 12 is rotated by a lever and a steering cylinder or a sprocket, a chain and a steering cylinder. Casters 15 are attached to other opposite corners of the vehicle body 10. A touch switch 16 is attached to one side of the traveling motor 14 in the vehicle traveling direction. The touch switch 16 outputs a signal when it comes into contact with an obstacle or the like. As shown in FIG. It is attached to the traveling motor 14 via a cushioning member 17 such as.
【０００８】 図４に示すように走行モータ１４が車体１０より外方に突出するとタッチスイ ッチ１６も車体１０より外方に突出して車体走行方向に向うので、車体１０の走 行時又は操舵・駆動輪の旋回時に走行モータ１４が車体１０より外方に突出して 障害物、人間と接する直前にタッチスイッチ１６が障害物、人間に接して信号を 出力する。 この信号を走行モータ１４の駆動制御回路やステアリングシリンダの伸縮制御 回路にフィードバックして走行モータ１４を停止、ステアリングシリンダを停止 し、その後は走行モータ１４が障害物、人間と離れる方向のみ走行、旋回可能と し、タッチスイッチ１６が障害物、人間と離れて信号が出力されなくなったらど の方向にも走行、旋回できるようにする。 これによって、走行モータ１４が障害物、人間に衝突することを防止できるか ら、ブラケット１１の旋回中心１１ａと車体１０の外側面１０ａとの間の距離を 走行モータ１４の長さより短かくでき、駆動輪１３間の距離Ｌ1 を車体全長に対 して長くして車体安定性を向上できるし、車体１０を小型化することも可能とな る。As shown in FIG. 4, when the traveling motor 14 projects outward from the vehicle body 10, the touch switch 16 also projects outward from the vehicle body 10 and faces the vehicle traveling direction. When the drive wheels turn, the traveling motor 14 projects outward from the vehicle body 10 and the touch switch 16 contacts the obstacle or the human and outputs a signal immediately before contacting the obstacle or the human. This signal is fed back to the drive control circuit of the traveling motor 14 and the expansion / contraction control circuit of the steering cylinder to stop the traveling motor 14 and stop the steering cylinder. After that, the traveling motor 14 travels only in the direction away from obstacles and people, and turns. If possible, the touch switch 16 can run and turn in any direction when no signal is output apart from an obstacle or a person. As a result, the traveling motor 14 can be prevented from colliding with an obstacle or a person, so that the distance between the turning center 11a of the bracket 11 and the outer side surface 10a of the vehicle body 10 can be made shorter than the length of the traveling motor 14. The distance L 1 between the drive wheels 13 can be increased relative to the entire length of the vehicle body to improve the vehicle body stability, and the vehicle body 10 can be downsized.
【０００９】 また、タッチスイッチ１６は緩衝材１７を介して走行モータ１４に取付けてあ るから、タッチスイッチ１６が障害物、人間と接した時の衝撃を緩衝材１７で吸 収して走行モータ１４の破損、人間を傷つけることを確実に防止できるし、特に 前述のタッチスイッチ１６の信号によって車体１０が走行停止した際に車体１０ が慣性によって若干走行した時にタッチスイッチ１６の変位を緩衝材１７で吸収 して走行モータ１４に伝えることがなく、その慣性による若干の車体走行によっ て走行モータ１４を破損したり、人間を傷つけることがない。 なお、駆動輪１３と走行モータ１４を備えたブラケット１１は車体１０の前側 隅部あるいは後側隅部にそれぞれ一対旋回可能に取付けても良いし、車体１０の ４隅にブラケット１１を旋回可能に取付けても良い。Further, since the touch switch 16 is attached to the traveling motor 14 via the cushioning material 17, the cushioning material 17 absorbs an impact when the touch switch 16 comes into contact with an obstacle or a person, and the traveling motor 14 is absorbed. It is possible to surely prevent the damage of 14 and the injury of human beings. Especially, when the vehicle body 10 stops traveling due to the signal of the touch switch 16 described above, the displacement of the touch switch 16 when the vehicle body 10 slightly travels due to inertia 17 Is not absorbed and is not transmitted to the traveling motor 14, and the traveling motor 14 is not damaged or injured by a slight amount of vehicle running due to its inertia. The brackets 11 having the drive wheels 13 and the traveling motors 14 may be attached to the front corners or the rear corners of the vehicle body 10 so as to be pivotable in pairs, or the brackets 11 may be pivoted to the four corners of the vehicle body 10. You may install it.

走行モータ１４が障害物、人間と衝突する以前にタッチスイッチ１６が接して 信号を出力するから、その信号によってその衝突を感知して走行モータ１４と障 害物、人間の衝突を防止する操作ができて走行モータ１４を破損、人間を傷つけ ること防止できる。 したがって、ブラケット１１の取付け位置を走行モータ１４が車体１０より外 方に突出する位置として駆動輪１３間の距離を車体全長に対して長くし車体安定 性を向上できるし、車体の小型化が可能となる。 タッチスイッチ１６と障害物・人間が接した時の衝撃を緩衝材１７で吸収して 走行モータ１４の破損、人間を傷つけることを確実に防止できる。 The touch switch 16 contacts and outputs a signal before the traveling motor 14 collides with an obstacle or a person. Therefore, the operation can be detected by detecting the collision by the signal to prevent the traveling motor 14 from colliding with an obstacle or a person. This can prevent the traveling motor 14 from being damaged and injuring a person. Therefore, the mounting position of the bracket 11 is set at a position where the traveling motor 14 projects outward from the vehicle body 10, and the distance between the drive wheels 13 is made longer with respect to the entire vehicle body length to improve the vehicle body stability and the vehicle body can be downsized. Becomes It is possible to reliably prevent the shock when the touch switch 16 comes in contact with an obstacle / human being absorbed by the cushioning material 17 from damaging the traveling motor 14 and injuring a human.
