Description

本発明は、車両搬送装置に関するものである。   The present invention relates to a vehicle transport device.

従来、任意の位置に停車した車両を駐車施設における所定位置に搬送できるようにした入出車装置の一般的技術水準を示すものとしては、例えば、特許文献１がある。   For example, Patent Document 1 shows a general technical level of an entry / exit device that can transport a vehicle stopped at an arbitrary position to a predetermined position in a parking facility.

特許文献１に示される装置は、それぞれ車両支持機構及び走行機構を備える左側搬送台車と右側搬送台車とからなり、該左側搬送台車と右側搬送台車とがそれぞれ独立して移動しつつ、協働して車両を支持し、搬送するようになっている。   The apparatus shown in Patent Document 1 includes a left conveyance carriage and a right conveyance carriage each having a vehicle support mechanism and a traveling mechanism, and the left conveyance carriage and the right conveyance carriage cooperate with each other while moving independently. The vehicle is supported and transported.

前記左側搬送台車と右側搬送台車は、無線通信によってリアルタイムに情報交換を行うことにより、協働している。   The left transport cart and the right transport cart cooperate by exchanging information in real time by wireless communication.

特開２００４−１６９４５１号公報JP 2004-169451 A

しかしながら、特許文献１に示されるような搬送台車では、車両の左右両側に充分な空きスペースがない場合、該車両の左右両側に搬送台車が寄り付くことができず、車両を搬送することができなくなるという欠点を有していた。   However, in the transport cart as shown in Patent Document 1, if there is not enough free space on both the left and right sides of the vehicle, the transport cart cannot approach the left and right sides of the vehicle, and the vehicle cannot be transported. Had the disadvantages.

又、車両の試験設備等においては、作業員が数人で車両を押しながら移動させることもあり、このような場合、作業員の負担が大きく、手間と時間がかかってしまうため、簡単な構成で車両を確実に搬送できる装置の開発が望まれていた。   Also, in vehicle testing facilities, etc., several workers may move while pushing the vehicle. In such a case, the burden on the worker is heavy, and it takes time and effort, so a simple configuration is required. Therefore, it has been desired to develop a device that can reliably convey the vehicle.

本発明は、斯かる実情に鑑み、車両の左右両側に充分な空きスペースがなくても、簡単な構成で車両を確実に搬送し得る車両搬送装置を提供しようとするものである。   In view of such a situation, the present invention is intended to provide a vehicle transport device that can reliably transport a vehicle with a simple configuration even if there is not enough free space on both the left and right sides of the vehicle.

本発明は、走行駆動装置により全方向に自走可能で且つ車両の前後の少なくとも一方から車両下部に進入可能な台車本体と、
該台車本体の台車フレームに連結部材を介して取り付けられるリフターフレームに、前記台車フレームの側面に沿う格納位置と前記車両の各車輪を前後から挟み付けるように支持しつつリフトアップする展開位置との間で回動自在な一対のリフトバーを、前記車両の車輪に対応させて枢着することによって形成したリフターと
を備えたことを特徴とする車両搬送装置にかかるものである。 The present invention is a cart body that can be self-propelled in all directions by a travel drive device and can enter the lower part of the vehicle from at least one of the front and rear sides of the vehicle ,
The lifter frame attached to the bogie frame of the bogie main body via a connecting member includes a retracted position along the side surface of the bogie frame and a deployment position that lifts up while supporting each wheel of the vehicle from the front and rear. And a lifter formed by pivotally attaching a pair of lift bars that can rotate between them corresponding to the wheels of the vehicle.

上記手段によれば、以下のような作用が得られる。   According to the above means, the following operation can be obtained.

車両を搬送する際には、台車本体を車両下部に進入させ、リフターのリフトバーを格納位置から回動させ、各車輪を前後から挟み付けるように支持しつつリフトアップする展開位置まで回動させると、車両がリフターによって支持され、この状態で、走行駆動装置により台車本体を自走させれば、車両を搬送することが可能となる。   When transporting the vehicle, if the main body of the carriage enters the lower part of the vehicle, the lift bar of the lifter is rotated from the storage position, and is rotated to the deployment position where it is lifted up while supporting each wheel to be sandwiched from the front and rear. The vehicle is supported by the lifter, and in this state, the vehicle can be transported if the carriage main body is driven by the traveling drive device.

この結果、特許文献１に示されるような搬送台車とは異なり、車両の左右両側に充分な空きスペースがなくても、車両の前後の少なくとも一方には必ずスペースはあるため、台車本体を車両下部に進入させることさえできれば、車両を搬送することができなくなる心配はない。   As a result, unlike the transport cart as shown in Patent Document 1, there is always a space in at least one of the front and rear of the vehicle even if there is not enough free space on the left and right sides of the vehicle. As long as the vehicle can enter the vehicle, there is no worry that the vehicle cannot be transported.

又、本発明の車両搬送装置を車両の試験設備等において利用すれば、作業員が数人で車両を押しながら移動させなくて済み、作業員の負担が大幅に軽減され、手間と時間がかからなくなり、作業効率を向上させることが可能となる。   In addition, if the vehicle transport device of the present invention is used in a vehicle testing facility or the like, a few workers do not have to move the vehicle while pushing the vehicle, the burden on the worker is greatly reduced, and labor and time are required. It becomes possible to improve work efficiency.

前記車両搬送装置においては、前記台車フレームに水平旋回自在に取り付けられた転向フレームの中心部に、走行車輪を回転駆動自在に配設した走行ユニットにより、前記走行駆動装置を構成することができる。   In the vehicle transport device, the travel drive device can be configured by a travel unit in which travel wheels are rotatably disposed at the center of a turning frame that is mounted on the carriage frame so as to be horizontally rotatable.

この場合、前記走行ユニットを台車フレームの前後方向へ間隔をあけて配設し、各走行ユニットの転向フレームの外周に設けたリングギヤに、該リングギヤ間に配設される転向駆動ピニオンを噛合させ、該転向駆動ピニオンを回転駆動することにより、前記各走行ユニットの転向フレームを同期して旋回させるよう構成することができ、このようにすると、一つの駆動系によって走行ユニットの走行車輪の向きを同時に変更することが可能となり、装置全体の重量を軽減し且つコストを削減する上で有効となる。   In this case, the traveling unit is disposed with an interval in the front-rear direction of the carriage frame, and a turning drive pinion disposed between the ring gears is engaged with a ring gear provided on the outer periphery of the turning frame of each traveling unit, By rotating the turning drive pinion, the turning frames of the traveling units can be configured to rotate in synchronization. With this configuration, the direction of the traveling wheels of the traveling unit can be simultaneously controlled by one drive system. This can be changed, and is effective in reducing the weight of the entire apparatus and reducing the cost.

一方、前記車両搬送装置においては、前記台車フレーム及びリフターフレームのいずれか一方に設けられ且つ上下方向へ延びるピンと、前記台車フレーム及びリフターフレームのいずれか他方に設けられ且つ前記ピンに嵌装されるブラケットとから前記連結部材を構成し、前記リフターに加わる車両の荷重を前記台車本体の走行駆動装置に伝えないよう構成することができ、このようにすると、走行駆動装置の走行車輪の耐荷重を大きくしなくて済み、該走行車輪の外径が小さく抑えられ、車両下部に進入させる必要があることから高さが制限される台車本体に走行車輪を搭載する上で有効となる。   On the other hand, in the vehicle transport device, a pin provided on one of the cart frame and the lifter frame and extending in the vertical direction, and a pin provided on the other of the cart frame and the lifter frame and fitted on the pin. The connecting member is constituted by a bracket, and the load of the vehicle applied to the lifter can be configured not to be transmitted to the traveling drive device of the bogie body. In this way, the load resistance of the traveling wheels of the traveling drive device can be reduced. It is not necessary to increase the size, and the outer diameter of the traveling wheel is suppressed to be small, and since it is necessary to enter the lower part of the vehicle, it is effective for mounting the traveling wheel on a cart body whose height is limited.

本発明の車両搬送装置によれば、車両の左右両側に充分な空きスペースがなくても、簡単な構成で車両を確実に搬送し得るという優れた効果を奏し得る。   According to the vehicle transport device of the present invention, it is possible to achieve an excellent effect that the vehicle can be transported reliably with a simple configuration even if there is not enough free space on both the left and right sides of the vehicle.

次に、上記実施例の作用を説明する。   Next, the operation of the above embodiment will be described.

車両１を搬送する際には、先ず、遠隔操作器１０の電源スイッチ１１をオンにし、台車本体３を車両１の後方に位置させ、リフター４のリフトバー４ｂを全て格納位置に回動させた状態から、リフター単独展開ボタン２１を押してリフター４のリフトバー４ｂのうち車両１の後側の車輪１ａの後方に配置されるリフトバー４ｂのみを単独で展開位置に回動させておく。   When transporting the vehicle 1, first, the power switch 11 of the remote controller 10 is turned on, the cart body 3 is positioned behind the vehicle 1, and all the lift bars 4 b of the lifter 4 are rotated to the storage position. Then, the lifter single deployment button 21 is pushed, and only the lift bar 4b disposed behind the wheel 1a on the rear side of the vehicle 1 among the lift bars 4b of the lifter 4 is independently rotated to the deployment position.

続いて、前記遠隔操作器１０の原点復帰転向ボタン１９を押して走行駆動装置２の二基の走行ユニット２Ａの走行車輪２ｂの向きを予め設定した原点（例えば、図１に示す向き）に一旦復帰させた後、前記遠隔操作器１０の右転向ボタン１８を押して走行駆動装置２の二基の走行ユニット２Ａの転向フレーム２ａを右回転（右旋回）させる方向へ回転駆動することにより走行車輪２ｂの向きを右転向させ、図１に示す向きから９０°位相を変える。   Subsequently, the home position return turning button 19 of the remote controller 10 is pressed to temporarily return the travel wheels 2b of the two travel units 2A of the travel drive device 2 to a preset origin (for example, the direction shown in FIG. 1). After that, the right turning button 18 of the remote controller 10 is pushed to rotate the turning frame 2a of the two traveling units 2A of the traveling drive device 2 in the direction to rotate right (turn right), thereby driving wheel 2b. 1 is turned to the right, and the phase is changed by 90 ° from the direction shown in FIG.

この後、前記遠隔操作器１０の前進ボタン１３を押して台車本体３を前進させると、該台車本体３を車両１下部に進入させることが可能となる。   Thereafter, when the forward movement button 13 of the remote controller 10 is pressed to advance the carriage main body 3, the carriage main body 3 can enter the lower part of the vehicle 1.

ここで、前記リフター４のリフトバー４ｂのうち車両１の後側の車輪１ａの後方に配置されるリフトバー４ｂのみを単独で展開位置に回動させてあるため、該リフトバー４ｂが車両１の後側の車輪１ａに接触する位置まで前記台車本体３を前進させ停止させるようにすれば、特別なセンサ等を用いなくても、車両１に対する台車本体３の位置決めを簡単且つ自動的に行うことができる。   Here, of the lift bar 4b of the lifter 4, only the lift bar 4b disposed behind the wheel 1a on the rear side of the vehicle 1 is independently rotated to the unfolded position. If the carriage main body 3 is moved forward to a position where it touches the wheel 1a and stopped, the carriage main body 3 can be easily and automatically positioned with respect to the vehicle 1 without using a special sensor or the like. .

この状態から、前記遠隔操作器１０のリフター全部展開ボタン２２を押すと、既に展開位置にあるリフター４のリフトバー４ｂを除く残りのリフトバー４ｂ全部が格納位置から展開位置に回動するため、各車輪１ａを前後から挟み付けるように支持しつつリフトアップすることが可能となる。   When the lifter full deployment button 22 of the remote controller 10 is pressed from this state, all the remaining lift bars 4b except the lift bar 4b of the lifter 4 already in the deployed position rotate from the retracted position to the deployed position. It becomes possible to lift up while supporting 1a so that it may be pinched | interposed from the front and back.

次に、前記遠隔操作器１０の前進ボタン１３を押せば、車両１を前進させる方向へ搬送することが可能となり、前記遠隔操作器１０の後進ボタン１４を押せば、車両１を後進させる方向へ搬送することが可能となる。該台車本体３を前進或いは後進させている間に前記遠隔操作器１０の高速ボタン２３を押すと、走行速度を増加させることが可能となる。   Next, if the forward button 13 of the remote controller 10 is pressed, the vehicle 1 can be transported in the forward direction. If the reverse button 14 of the remote controller 10 is pressed, the vehicle 1 is moved backward. It can be transported. When the high speed button 23 of the remote controller 10 is pushed while the cart body 3 is moved forward or backward, the traveling speed can be increased.

又、前記遠隔操作器１０の左転向ボタン１７を押して走行駆動装置２の二基の走行ユニット２Ａの転向フレーム２ａを左回転（左旋回）させる方向へ回転駆動することにより走行車輪２ｂの向きを左転向させ、例えば、左４５°の向きで、前記遠隔操作器１０の前進ボタン１３を押せば、車両１を左斜め前方へ前進させる方向へ搬送することが可能となり、前記遠隔操作器１０の後進ボタン１４を押せば、車両１を右斜め後方へ後進させる方向へ搬送することが可能となる。   Further, the direction of the traveling wheel 2b is turned by rotating the turning frame 2a of the two traveling units 2A of the traveling drive device 2 in the direction of turning left (turning left) by pressing the left turning button 17 of the remote controller 10. For example, if the forward button 13 of the remote controller 10 is pushed in the direction of 45 ° to the left, the vehicle 1 can be transported in the direction of moving forward diagonally to the left. If the reverse button 14 is pressed, the vehicle 1 can be transported in the direction of moving backward in the diagonally rightward direction.

更に又、前記遠隔操作器１０の原点復帰転向ボタン１９を押して走行駆動装置２の二基の走行ユニット２Ａの走行車輪２ｂの向きを予め設定した原点（例えば、図１に示す向き）に一旦復帰させた後、前記遠隔操作器１０の左回転ボタン１５を押せば、前記走行駆動装置２の二基の走行ユニット２Ａの走行車輪２ｂを互いに相反する方向へ回転駆動することにより前記車両１が搭載された台車本体３をその位置で左回転（左旋回）させ、車両１の向きを変更することが可能となり、前記遠隔操作器１０の右回転ボタン１６を押せば、前記走行駆動装置２の二基の走行ユニット２Ａの走行車輪２ｂを左回転時とは反対となる互いに相反する方向へ回転駆動することにより前記車両１が搭載された台車本体３をその位置で右回転（右旋回）させ、車両１の向きを変更することが可能となる。   Furthermore, the origin return turning button 19 of the remote controller 10 is pressed to temporarily return the orientation of the traveling wheels 2b of the two traveling units 2A of the traveling drive device 2 to a preset origin (for example, the direction shown in FIG. 1). Then, when the left rotation button 15 of the remote controller 10 is pressed, the vehicle 1 is mounted by rotating the traveling wheels 2b of the two traveling units 2A of the traveling drive device 2 in directions opposite to each other. It is possible to rotate the left side of the carriage body 3 at that position (turn left) to change the direction of the vehicle 1, and press the right rotation button 16 of the remote controller 10. By rotating and driving the traveling wheel 2b of the base traveling unit 2A in opposite directions opposite to the counterclockwise rotation, the cart body 3 on which the vehicle 1 is mounted is rotated to the right (turns right) at that position. , It is possible to change both 1 orientation.

前記車両１が搭載された台車本体３を所定の位置へ移動させ、必要に応じて車両１の向きを変更した後、前記遠隔操作器１０のリフター格納ボタン２０を押すと、前記リフター４のリフトバー４ｂが格納位置に回動し、前記車両１がリフトアップされていた状態から地上に降ろされ、走行車輪２ｂの向きを図１に示す向きから９０°位相を変えた状態で、前記遠隔操作器１０の後進ボタン１４を押して台車本体３を後進させると、該台車本体３を車両１下部から引き出すことが可能となり、車両１の搬送が完了する。   After the carriage body 3 on which the vehicle 1 is mounted is moved to a predetermined position and the direction of the vehicle 1 is changed as necessary, when the lifter storage button 20 of the remote controller 10 is pressed, the lift bar of the lifter 4 4b is rotated to the retracted position, the vehicle 1 is lowered to the ground from the lifted state, and the direction of the traveling wheel 2b is changed by 90 ° from the direction shown in FIG. When the carriage main body 3 is moved backward by pushing the reverse button 14 of 10, the carriage main body 3 can be pulled out from the lower part of the vehicle 1 and the conveyance of the vehicle 1 is completed.

尚、上述の例では、前記台車本体３を車両１の後方から進入させる場合について説明したが、該台車本体３を車両１の前方から進入させても同様に車両１の搬送を行えることは言うまでもない。   In the above-described example, the case where the cart body 3 is entered from the rear of the vehicle 1 has been described, but it goes without saying that the vehicle 1 can be transported in the same manner even if the cart body 3 is entered from the front of the vehicle 1. Yes.

この結果、特許文献１に示されるような搬送台車とは異なり、車両１の左右両側に充分な空きスペースがなくても、車両１の前後の少なくとも一方には必ずスペースはあるため、台車本体３を車両１下部に進入させることさえできれば、車両１を搬送することができなくなる心配はない。   As a result, unlike the transport carriage as shown in Patent Document 1, there is always a space in at least one of the front and rear of the vehicle 1 even if there are not enough empty spaces on the left and right sides of the vehicle 1. As long as the vehicle 1 can enter the lower part of the vehicle 1, there is no concern that the vehicle 1 cannot be transported.

又、本実施例の車両搬送装置を車両１の試験設備等において利用すれば、作業員が数人で車両１を押しながら移動させなくて済み、作業員の負担が大幅に軽減され、手間と時間がかからなくなり、作業効率を向上させることが可能となる。   Moreover, if the vehicle conveyance device of the present embodiment is used in the test facility of the vehicle 1, it is not necessary for the worker to move the vehicle 1 while pushing the vehicle 1, and the burden on the worker is greatly reduced. It takes less time and the work efficiency can be improved.

更に又、前記車両搬送装置においては、前記台車フレーム３ａに水平旋回自在に取り付けられた転向フレーム２ａの中心部に、走行車輪２ｂを回転駆動自在に配設した走行ユニット２Ａにより、前記走行駆動装置２を構成し、前記走行ユニット２Ａを台車フレーム３ａの前後方向へ所要の間隔をあけて配設し、各走行ユニット２Ａの転向フレーム２ａの外周に設けたリングギヤ２ｅに、該リングギヤ２ｅ間に配設される転向駆動ピニオン２ｆを噛合させ、該転向駆動ピニオン２ｆを回転駆動することにより、前記各走行ユニット２Ａの転向フレーム２ａを同期して旋回させるよう構成してあるため、一つの駆動系によって走行ユニット２Ａの走行車輪２ｂの向きを同時に変更することが可能となり、装置全体の重量を軽減し且つコストを削減する上で有効となる。   Furthermore, in the vehicle transport device, the travel drive device includes a travel unit 2A in which travel wheels 2b are rotatably disposed at the center of a turning frame 2a that is mounted on the carriage frame 3a so as to be horizontally turnable. 2, the traveling unit 2A is disposed in the front-rear direction of the carriage frame 3a with a predetermined interval, and the ring gear 2e provided on the outer periphery of the turning frame 2a of each traveling unit 2A is disposed between the ring gears 2e. Since the turning drive pinion 2f is meshed, and the turning drive pinion 2f is rotationally driven, the turning frame 2a of each traveling unit 2A is rotated in synchronization. The direction of the traveling wheel 2b of the traveling unit 2A can be changed at the same time, reducing the weight of the entire device and reducing the cost. It becomes effective on that.

一方、前記車両搬送装置においては、前記台車フレーム３ａ及びリフターフレーム４ａのいずれか一方に設けられ且つ上下方向へ延びるピン５ａと、前記台車フレーム３ａ及びリフターフレーム４ａのいずれか他方に設けられ且つ前記ピン５ａに嵌装されるブラケット５ｂとから前記連結部材５を構成し、前記リフター４に加わる車両１の荷重を前記台車本体３の走行駆動装置２に伝えないよう構成してあるため、走行駆動装置２の走行車輪２ｂの耐荷重を大きくしなくて済み、該走行車輪２ｂの外径が小さく抑えられ、車両１下部に進入させる必要があることから高さが制限される台車本体３に走行車輪２ｂを搭載する上で有効となる。   On the other hand, in the vehicle transport device, a pin 5a provided on one of the carriage frame 3a and the lifter frame 4a and extending in the vertical direction, and provided on one of the carriage frame 3a and the lifter frame 4a, and Since the connecting member 5 is composed of the bracket 5b fitted to the pin 5a and the load of the vehicle 1 applied to the lifter 4 is not transmitted to the travel drive device 2 of the carriage body 3, the travel drive It is not necessary to increase the load resistance of the traveling wheel 2b of the device 2, the outer diameter of the traveling wheel 2b is kept small, and it is necessary to enter the lower part of the vehicle 1, so that it travels to the cart body 3 whose height is limited. This is effective in mounting the wheel 2b.

こうして、車両１の左右両側に充分な空きスペースがなくても、簡単な構成で車両１を確実に搬送し得る。   In this way, the vehicle 1 can be reliably transported with a simple configuration even if there are not enough empty spaces on the left and right sides of the vehicle 1.

尚、本発明の車両搬送装置は、上述の実施例にのみ限定されるものではなく、台車フレームに伸縮機構を設けるようにすれば、ホイールベースの異なる車両にも適用可能となること等、その他、本発明の要旨を逸脱しない範囲内において種々変更を加え得ることは勿論である。   The vehicle transport device of the present invention is not limited to the above-described embodiment, and can be applied to a vehicle having a different wheel base by providing an expansion / contraction mechanism on the carriage frame. Of course, various modifications can be made without departing from the scope of the present invention.
