Description

本発明は、車体移送装置に関するものであり、より詳細には、自動車製造工場において、組立て中の車体を1つの組立ラインから隣接する他の組立ラインへ移送する車体移送装置に関するものである。   The present invention relates to a vehicle body transfer device, and more particularly to a vehicle body transfer device that transfers a vehicle body being assembled from one assembly line to another adjacent assembly line in an automobile manufacturing factory.

例えば、一般的な自動車製造工場における自動車の組立作業は、人手により、あるいは、ロボットを用いた流れ作業により行われるが、そのために、多岐に渡る組立工程を含む組立ラインが複数列形成される。そして、その場合、組立て中の車体は、床面と同高のフラットコンベアにより、1つの組立ライン(Aライン)から次工程の組立ライン(Bライン)へ移送されるが、その移送は、Aラインの末端とBラインの始端とを結ぶ連結ラインを介して行われる。   For example, an automobile assembly operation in a general automobile manufacturing factory is performed manually or by a flow operation using a robot. For that purpose, a plurality of assembly lines including various assembly processes are formed. In this case, the vehicle body being assembled is transferred from one assembly line (A line) to the next process assembly line (B line) by a flat conveyor having the same height as the floor surface. This is done via a connecting line connecting the end of the line and the start of the B line.

そのため、Aラインの途中からBラインへ移送したい場合においても、一旦Aラインの末端まで進行させ、その後連結ラインを介してBラインの先端に移送しなければならないという不都合があり、それは、作業効率の低下の一因ともなっていた。   For this reason, even if it is desired to transfer from the middle of the A line to the B line, there is a disadvantage that it must be once advanced to the end of the A line and then transferred to the tip of the B line via the connecting line, which is a work efficiency. Also contributed to the decline.

先ず、図1及び図2に示される実施形態について説明する。この実施形態における車体移送装置は、自走機能を備えた本体1と、本体1から前方に延びるホイール付きフォーク2、2aと、フォーク2、2aに設置される支持フレーム11とから成り、支持フレーム11に走行支持枠13とタイヤ浮上保持手段とが配備される。本装置は無人で遠隔操作可能に構成することもできるが、通例、有人操作によるものとされ、本体1に、作業者が乗るステップ3と、操作ハンドル4とが配備される。本体1の自走機能としては、例えば、一般のフォークリフトにおける自走機能を転用することができる。   First, the embodiment shown in FIGS. 1 and 2 will be described. The vehicle body transfer device according to this embodiment includes a main body 1 having a self-propelling function, forks 2 and 2a with wheels extending forward from the main body 1, and a support frame 11 installed on the forks 2 and 2a. 11, a travel support frame 13 and tire levitation holding means are provided. Although this apparatus can be configured to be unattended and remotely operable, it is usually based on manned operation, and the main body 1 is provided with a step 3 on which an operator rides and an operation handle 4. As the self-propelled function of the main body 1, for example, a self-propelled function in a general forklift can be diverted.

フォーク2、2aは、通例一対平行に配置され、それぞれ先端部裏面に走行ホイール5が設置される。支持フレーム11は、フォーク2、2aに直交して延びる横枠材12を有する。この横枠材12は、フォーク2、2a上に位置する一半部と、フォーク2、2aから外れて延びる他半部とから成り、その一半部に走行支持枠13が設置され、その他半部に、タイヤ浮上保持手段を構成するタイヤ支持枠14が設置される。また、各フォーク2、2aの上面に、支持フレーム11の横枠材12から延びる連結アーム6の一端を枢支する軸受7が配備される。   The forks 2 and 2a are usually arranged in parallel as a pair, and a traveling wheel 5 is installed on the back surface of the tip portion. The support frame 11 has a horizontal frame member 12 extending perpendicularly to the forks 2 and 2a. This horizontal frame member 12 is composed of one half located on the forks 2 and 2a and the other half extending away from the forks 2 and 2a, and a traveling support frame 13 is installed in the other half, and the other half The tire support frame 14 constituting the tire floating holding means is installed. A bearing 7 is provided on the upper surface of each fork 2, 2 a to pivotally support one end of the connecting arm 6 extending from the lateral frame member 12 of the support frame 11.

走行支持枠13はコ字形状を呈し、外側のフォーク2を跨ぐようにして、その開放側端部が横枠材12の下面に溶接固定され、その適宜個所にキャスター18が取り付けられる。また、タイヤ支持枠14は、横枠材12と、後端部が横枠材12の下面に固定された一対の縦枠材15、16とで構成され、通例、外側の縦枠材16にキャスター18aが取り付けられる。縦枠材15、16の先端部間は開放され、そこに、該開放部を開閉する受板17が配備される。受板17は、タイヤ10の周面を受ける関係で、タイヤ10の周面に対応する傾斜板として形成される。   The traveling support frame 13 has a U-shape, and its open side end is welded and fixed to the lower surface of the horizontal frame member 12 so as to straddle the outer fork 2, and casters 18 are attached to appropriate portions thereof. The tire support frame 14 includes a horizontal frame member 12 and a pair of vertical frame members 15 and 16 whose rear ends are fixed to the lower surface of the horizontal frame member 12. A caster 18a is attached. The ends of the vertical frame members 15 and 16 are opened, and a receiving plate 17 for opening and closing the open portions is provided there. The receiving plate 17 is formed as an inclined plate corresponding to the circumferential surface of the tire 10 in relation to receiving the circumferential surface of the tire 10.

受板17は、縦枠材15、16の先端部間を開閉するように動作する。図1乃至図3に示される実施形態における受板17は、その一端部が縦枠材15、16の一方(図示した例では縦枠材15)に枢支されて旋回することによってその開閉動作をするが、後述する実施形態におけるように、進退駆動されて開閉動作をするように構成することもできる。   The receiving plate 17 operates so as to open and close between the front ends of the vertical frame members 15 and 16. The receiving plate 17 in the embodiment shown in FIGS. 1 to 3 is opened and closed by pivoting one end of which is pivotally supported by one of the vertical frame members 15 and 16 (the vertical frame member 15 in the illustrated example). However, as in an embodiment described later, it can be configured to be opened and closed to open and close.

旋回方式による場合は、一方の縦枠材15の端部上に回動板20が軸着され、回動板20に受板17が固定される(図1参照)。回動板20には、旋回操作する際に握持する操作レバー22が取り付けられ、また、その上面から、縦枠材15に達するようにロックピン21が差し込まれる。回動板20は、このロックピン21を抜いた状態において受板17と一体に回動可能となる。受板17の先端部は、縦枠材16の内側面に設置されるブラケット23において支持される。なお、必要に応じ、走行支持枠13と内側の縦枠材15との間に連結杆24が架け渡される。   In the case of the turning method, the rotating plate 20 is pivotally mounted on the end portion of one vertical frame member 15, and the receiving plate 17 is fixed to the rotating plate 20 (see FIG. 1). An operation lever 22 that is gripped when performing a turning operation is attached to the rotating plate 20, and a lock pin 21 is inserted from the upper surface so as to reach the vertical frame member 15. The rotating plate 20 can be rotated integrally with the receiving plate 17 in a state where the lock pin 21 is removed. The front end portion of the receiving plate 17 is supported by a bracket 23 installed on the inner surface of the vertical frame member 16. Note that a connecting rod 24 is bridged between the travel support frame 13 and the inner vertical frame member 15 as necessary.

縦枠材15、16の中間部間に、受板17と平行に可動軸25が配設される。この可動軸25は、受板17と対をなしてタイヤ10を浮上させ、その浮上状態を保持するよう作用する。可動軸25は、横枠材12に設置される可動軸駆動シリンダー26によりその軸方向と直交方向に、即ち、受板17に向けて進退駆動される。そのために可動軸25は、可動軸駆動シリンダー26のロッド端に取り付けられるコ字状ブラケット27の両側板間において軸支され、可動軸駆動シリンダー26の作用で進退動作する。その進退動作を支持させるため、コ字状ブラケット27の各側板の上方延長部がそれぞれ、縦枠材15と縦枠材16の各上面に敷設されるガイドレール28、29に組み付けられるLMブロック30、31の内側面に固定される。   A movable shaft 25 is disposed between the intermediate portions of the vertical frame members 15 and 16 in parallel with the receiving plate 17. The movable shaft 25 acts as a pair with the receiving plate 17 to float the tire 10 and maintain the floating state. The movable shaft 25 is driven back and forth in a direction orthogonal to the axial direction thereof, that is, toward the receiving plate 17 by a movable shaft drive cylinder 26 installed on the horizontal frame member 12. For this purpose, the movable shaft 25 is pivotally supported between both side plates of a U-shaped bracket 27 attached to the rod end of the movable shaft drive cylinder 26, and moves forward and backward by the action of the movable shaft drive cylinder 26. In order to support the forward / backward movement, the upper extensions of the side plates of the U-shaped bracket 27 are assembled to the guide rails 28 and 29 laid on the upper surfaces of the vertical frame member 15 and the vertical frame member 16, respectively. , 31 is fixed to the inner surface.

かくして可動軸25は、可動軸駆動シリンダー26が進動作をするに伴い、ガイドレール28、29に沿って直線移動するLMブロック30、31に支持されたコ字状ブラケット27を介し、前進して受板17に近づき、逆に、可動軸駆動シリンダー26が退動作をするに伴い、後退して受板17から離れることになる。   Thus, the movable shaft 25 moves forward through the U-shaped bracket 27 supported by the LM blocks 30 and 31 that linearly move along the guide rails 28 and 29 as the movable shaft drive cylinder 26 moves forward. On the contrary, the movable shaft drive cylinder 26 moves backward and moves away from the receiving plate 17 as it approaches the receiving plate 17.

上記構成の装置によって車体のタイヤ10の1つを浮上させてその状態を保持させるには、車体1をその自走手段とハンドル操作によって所望位置に移動させ、更に、受板17を開き且つ可動軸25を後退させた状態にて、タイヤ10(例えば、右側前輪)が縦枠材15、16間に進入するように移動させる。タイヤ10を進入させた後受板17を閉じ、受板17の先端部をブラケット23において支持させる。また、ロックピン22を差し込んで、回動板20が回動しないようにロックする。   In order to float one of the tires 10 of the vehicle body and maintain the state by the apparatus having the above-described configuration, the vehicle body 1 is moved to a desired position by the self-propelling means and the handle operation, and the receiving plate 17 is opened and moved. With the shaft 25 retracted, the tire 10 (for example, the right front wheel) is moved so as to enter between the vertical frame members 15 and 16. After the tire 10 has entered, the receiving plate 17 is closed, and the tip of the receiving plate 17 is supported by the bracket 23. Further, the lock pin 22 is inserted to lock the rotation plate 20 so as not to rotate.

そして、必要に応じ、本体1を後退させて受板17をタイヤ10の踏面に当接させた後、可動軸駆動シリンダー26に進動作をさせて可動軸25を前進させ、タイヤ10の周面に当接させる。その後更に可動軸駆動シリンダー26に進動作させ、可動軸25でタイヤ10を押圧すると、タイヤ10は受板17に押さえられて後退できないために、可動軸25はタイヤ10の周面に沿ってその下側に入り込んでタイヤ10を迫り上げる。このようにしてタイヤ10を浮上させた時点で、可動軸駆動シリンダー26の動作を停止させる。かくしてタイヤ10は、受板17と可動軸25とに挟持されて、その浮上状態を維持することになる。   Then, if necessary, the main body 1 is moved backward to bring the receiving plate 17 into contact with the tread surface of the tire 10, and then the movable shaft drive cylinder 26 is advanced to move the movable shaft 25 forward. Abut. After that, when the tire 10 is further moved forward by the movable shaft drive cylinder 26 and the tire 10 is pressed by the movable shaft 25, the tire 10 is pressed by the receiving plate 17 and cannot be moved backward, so the movable shaft 25 is moved along the circumferential surface of the tire 10. It enters the lower side and pushes up the tire 10. When the tire 10 is lifted in this manner, the operation of the movable shaft drive cylinder 26 is stopped. Thus, the tire 10 is sandwiched between the receiving plate 17 and the movable shaft 25 and maintains its floating state.

このようにして車体の4輪のタイヤのうちの1輪を浮上させるに伴って車体が傾斜するが、その状態のまま車体1を所望方向に自走させることにより、当該車体を1つのラインから別のラインへ移送することができる。そして、車体1を所望位置に移送した後、可動軸駆動シリンダー26に退動作をさせて可動軸25を後退させることによりタイヤ10を接地させ、次いで、受板17の開放操作をした後本体1を後退させることにより、タイヤ10を縦枠材15、16間から出す。   In this way, the vehicle body tilts as one of the four tires of the vehicle body is levitated, but by moving the vehicle body 1 in a desired direction in that state, the vehicle body is removed from one line. Can be transferred to another line. Then, after the vehicle body 1 is transferred to a desired position, the movable shaft drive cylinder 26 is retracted to retract the movable shaft 25 to ground the tire 10, and then the receiving plate 17 is opened, and then the main body 1. , The tire 10 is taken out from between the vertical frame members 15 and 16.

図3及び図4に示す第2の実施形態は、上記第1の実施形態におけるタイヤ浮上手段を変更したもので、それ以外の構成は上記第1の実施形態における構成に準じる。即ち、自走機能を備えた本体1と、本体1から前方に延びるホイール付きフォーク2、2aと、フォーク2、2aに設置される支持フレーム11とから成り、支持フレーム11に走行支持枠13とタイヤ浮上保持手段とが配備されることに変わりはない。従って、第1の実施形態と共通の構成部分については共通の符号を付し、それらについての詳細な説明は省略する。   The second embodiment shown in FIGS. 3 and 4 is obtained by changing the tire floating means in the first embodiment, and other configurations are the same as those in the first embodiment. That is, it comprises a main body 1 having a self-propelling function, wheeled forks 2 and 2a extending forward from the main body 1, and a support frame 11 installed on the forks 2 and 2a. The tire levitation holding means is still provided. Therefore, the same reference numerals are given to the components common to the first embodiment, and detailed description thereof will be omitted.

この第2の実施形態の場合は、支持フレーム11を構成する横枠材12に、走行支持枠13が設置されると共に、タイヤ浮上保持手段を構成するタイヤ支持枠14が設置される。このタイヤ支持枠14は、横枠材12と、後端部が横枠材12の下面に固定された一対の縦枠材15、16とで構成され、通例、外側の縦枠材16にキャスター18が取り付けられ、更に、縦枠材15、16の先端部間が開放されることは、第1の実施形態と同じであるが、第2の実施形態の場合は、縦枠材15、16の中間部間に受板71が配備される点で相違する。受板71は傾斜板によって形成され、必要に応じ、タイヤ10の周面に対応して回動可能となるように、その両側部が軸支される。この受板71は、第1の実施形態における受板17のように水平方向に旋回することはない。   In the case of the second embodiment, a travel support frame 13 is installed on the horizontal frame member 12 that constitutes the support frame 11, and a tire support frame 14 that constitutes a tire suspension holding means is installed. The tire support frame 14 is composed of a horizontal frame member 12 and a pair of vertical frame members 15 and 16 whose rear end portions are fixed to the lower surface of the horizontal frame member 12. 18 is attached, and furthermore, the opening between the front ends of the vertical frame members 15 and 16 is the same as in the first embodiment, but in the case of the second embodiment, the vertical frame members 15 and 16 are opened. The difference is that a receiving plate 71 is provided between the intermediate portions. The receiving plate 71 is formed of an inclined plate, and both sides thereof are pivotally supported so as to be rotatable corresponding to the peripheral surface of the tire 10 as necessary. The receiving plate 71 does not turn in the horizontal direction unlike the receiving plate 17 in the first embodiment.

内側に位置する縦枠材15は外側に位置する縦枠材16よりも長尺にされ、その先端部に可動軸72が、軸受73を介して旋回可能に配設される。この可動軸72は、受板71と協働してタイヤ10を浮上させ、その浮上状態を保持するよう作用するもので、その先端部にキャスター74が設置される。可動軸72の旋回軸75から延びる旋回アーム75aが、芯軸75bを介して油圧シリンダー76のロッド77の先端部に連結され、以て、旋回軸75と一体の可動軸72が、油圧シリンダー76の動作に伴って旋回駆動される。   The vertical frame member 15 located on the inner side is made longer than the vertical frame member 16 located on the outer side, and a movable shaft 72 is disposed at the tip thereof so as to be rotatable via a bearing 73. The movable shaft 72 operates to float the tire 10 in cooperation with the receiving plate 71 and maintain the floating state, and a caster 74 is installed at the tip portion thereof. A turning arm 75a extending from the turning shaft 75 of the movable shaft 72 is connected to the tip of the rod 77 of the hydraulic cylinder 76 via the core shaft 75b, so that the movable shaft 72 integral with the turning shaft 75 is connected to the hydraulic cylinder 76. It is swiveled along with the operation.

油圧シリンダー76は、その基端部が、フォーク2、2a上に跨るように配置されたプレート78上に旋回自在に軸支される。かくして油圧シリンダー76が伸動作をすると、直線状に近い状態にあったロッド77と旋回アーム75a(図3における仮想線表示を参照)は、旋回アーム75aが押されて回動するために芯軸75bから折れて屈曲状態となる(図3における実線表示を参照)。そして、旋回アーム75a及び旋回軸75と一体の可動軸72が旋回して縦枠材15と直交状態となることにより、縦枠材15、16の開放端が閉じられる。   The hydraulic cylinder 76 is pivotally supported on a plate 78 disposed so that the base end portion thereof straddles the forks 2 and 2a. Thus, when the hydraulic cylinder 76 is extended, the rod 77 and the swing arm 75a (refer to the phantom line display in FIG. 3) that are in a nearly linear state are rotated by the pivot arm 75a being pressed. It is bent from 75b to be bent (see solid line display in FIG. 3). Then, the movable shaft 72 integral with the swing arm 75a and the swing shaft 75 swings and becomes orthogonal to the vertical frame member 15, whereby the open ends of the vertical frame members 15 and 16 are closed.

逆に、上記のように縦枠材15、16の開放端が閉じられた状態において油圧シリンダー76が縮動作をすると、旋回アーム75aが引っ張られて逆方向に回動するため、屈曲状態にあったロッド77と旋回アーム75aが伸ばされて元の直線状態に戻り、可動軸72も逆方向に旋回して、縦枠材15と一直線状となり、以て、縦枠材15、16の開放端が開かれる(図3における仮想線表示を参照)。なお、符号79は、油圧シリンダー76に油圧を供給するための油圧パッケージポンプを示す。   On the other hand, when the hydraulic cylinder 76 is contracted in the state where the open ends of the vertical frame members 15 and 16 are closed as described above, the swing arm 75a is pulled and rotated in the reverse direction, so that it is in a bent state. The rod 77 and the swivel arm 75a are extended to return to the original straight state, and the movable shaft 72 is swung in the opposite direction to be in a straight line with the vertical frame member 15, so that the open ends of the vertical frame members 15 and 16 are opened. Is opened (see virtual line display in FIG. 3). Reference numeral 79 denotes a hydraulic package pump for supplying hydraulic pressure to the hydraulic cylinder 76.

この第2の実施形態に係る装置によって車体のタイヤ10の1つを浮上させてその状態を保持させるには、先ず、車体1をその自走手段とハンドル操作によって所望位置に移動させた後、油圧シリンダー76に縮動作をさせて可動軸72が縦枠材15と一直線状となるように旋回させ、縦枠材15、16の開放端を開いた状態にする。その状態において更に車体1を移動させ、タイヤ10(例えば、右側前輪)が縦枠材15、16間に進入して受板71に当接するようにする。   In order to float one of the tires 10 of the vehicle body and maintain the state thereof by the apparatus according to the second embodiment, first, after moving the vehicle body 1 to a desired position by its own traveling means and handle operation, The hydraulic cylinder 76 is contracted to rotate so that the movable shaft 72 is aligned with the vertical frame member 15, and the open ends of the vertical frame members 15 and 16 are opened. In this state, the vehicle body 1 is further moved so that the tire 10 (for example, the right front wheel) enters between the vertical frame members 15 and 16 and comes into contact with the receiving plate 71.

このようにしてタイヤ10を進入させて受板71に当接させた後、油圧シリンダー76に伸動作をさせて可動軸72を逆方向、即ち、閉じ方向に旋回させる。その際可動軸71は、縦枠材15と直角となるその旋回端に至る前の、縦枠材15に対して傾斜した状態においてタイヤ10に当接することになるが、その状態から更に旋回を進めることにより、タイヤ10が迫り上げられていく。そして、可動軸71が縦枠材15と直角となるその旋回端に至り、移動しない受板71との間においてタイヤ10を浮上させつつ挟持し、その浮上状態を維持する。   After the tire 10 is made to enter and contact the receiving plate 71 in this way, the hydraulic cylinder 76 is extended to turn the movable shaft 72 in the reverse direction, that is, in the closing direction. At that time, the movable shaft 71 comes into contact with the tire 10 in a state where it is inclined with respect to the vertical frame member 15 before reaching the turning end at a right angle to the vertical frame member 15. The tire 10 is pushed up by advancing. Then, the movable shaft 71 reaches the turning end at a right angle to the vertical frame member 15, holds the tire 10 while floating with the receiving plate 71 not moving, and maintains the floating state.

このようにして車体の4輪のタイヤのうちの1輪を浮上させて支持し、車体を傾斜させた状態において、車体1を所望方向に自走させることにより、当該車体を1つのラインから別のラインへ移送することができる。そして、車体1を所望位置に移送した後、油圧シリンダー76を縮動作させて可動軸72を、縦枠材15、16の先端部間が開く方向に旋回させると、タイヤ10は可動軸72から外れて接地するので、そのまま本体1を後退させることにより、タイヤ10を縦枠材15、16外に出すことができる。   In this way, one of the four tires of the vehicle body is levitated and supported, and the vehicle body 1 is separated from one line by allowing the vehicle body 1 to travel in a desired direction while the vehicle body is inclined. Can be transferred to the next line. Then, after the vehicle body 1 is transferred to a desired position, the hydraulic cylinder 76 is contracted to turn the movable shaft 72 in a direction in which the end portions of the vertical frame members 15 and 16 are opened. Since it comes off and grounds, the tire 10 can be taken out of the vertical frame members 15 and 16 by retracting the main body 1 as it is.

次いで、図5乃至図7に示される第3の実施形態について説明する。この実施形態における車体移送装置も、上記2つの実施形態と同様に、自走機能を備えた本体41と、本体41から前方に延びるように設置される、タイヤ浮上保持手段を備えた支持フレーム42とを備えて構成される。また、本体41に、ステップ43が設けられると共に、操作ハンドル44が設置される。   Next, a third embodiment shown in FIGS. 5 to 7 will be described. Similarly to the above-described two embodiments, the vehicle body transfer device in this embodiment also includes a main body 41 having a self-propelled function and a support frame 42 having tire levitation holding means installed to extend forward from the main body 41. And is configured. In addition, the main body 41 is provided with a step 43 and an operation handle 44.

支持フレーム42は、本体41に設置される横枠材45と、横枠材45から平行に延びる一対の縦枠材46、47とでコ字状に形成される。外側の縦枠材46は、その後半部がクランク形状にされ、その後端面に、後述する縦軸杆51と縦軸杆52にかかる力のバランス調整をする、負荷調整用シリンダー48が設置される。   The support frame 42 is formed in a U shape by a horizontal frame member 45 installed on the main body 41 and a pair of vertical frame members 46 and 47 extending in parallel from the horizontal frame member 45. The outer vertical frame member 46 has a crank shape at the rear half thereof, and a load adjusting cylinder 48 that adjusts the balance of forces applied to the vertical axis 杆 51 and the vertical axis 杆 52, which will be described later, is installed on the rear end face thereof. .

横枠材45及び縦枠材46、47は樋状であって、横枠材45内に横軸杆50が配設され、縦枠材46、47内にはそれぞれ、後端が横軸杆50に連結される縦軸杆51、52が配設される(図5、図7参照)。縦枠材46内に配設される縦軸杆51は、縦枠材46に対応するクランク状にされる。横軸杆50の端部は、それぞれ縦枠材46、47の後端部の側壁において支持され、その中間部に昇降駆動手段(図示していない)が設置される。その昇降駆動手段としては、油圧シリンダーやラック・ピニオン機構等を採用することができる。   The horizontal frame member 45 and the vertical frame members 46 and 47 are bowl-shaped, and a horizontal shaft rod 50 is disposed in the horizontal frame member 45, and the rear ends of the horizontal frame members 46 and 47 are respectively horizontal axis rods. Vertical axis rods 51 and 52 connected to 50 are disposed (see FIGS. 5 and 7). The vertical axis rod 51 disposed in the vertical frame member 46 has a crank shape corresponding to the vertical frame member 46. The end portions of the horizontal shaft rod 50 are supported on the side walls of the rear end portions of the vertical frame members 46 and 47, respectively, and lifting drive means (not shown) is installed in the middle portion thereof. As the raising / lowering driving means, a hydraulic cylinder, a rack and pinion mechanism or the like can be employed.

縦軸杆51、52の各後端の横軸杆50への連結は、直角部材53を介して行う(図7参照)。直角部材53は、短尺辺と長尺辺とを直交させたもので、そのコーナー部が横軸杆50によって軸支され、短尺辺の先端に縦軸杆51、52の端部が軸着される。その長尺辺は中間部が折曲可能に軸着され、端部が横枠材45において軸支される。   Connection of the rear ends of the vertical axis rods 51 and 52 to the horizontal axis rod 50 is performed through a right angle member 53 (see FIG. 7). The right-angle member 53 has a short side and a long side orthogonal to each other, and a corner portion of the right-angle member 53 is pivotally supported by a horizontal shaft 50, and ends of vertical shafts 51 and 52 are attached to the ends of the short side. The The long side is pivotally attached so that the middle part can be bent, and the end part is pivotally supported by the horizontal frame member 45.

また、縦軸杆51、52の先端部に、リンクプレート55を介してホイール56が取り付けられる。リンクプレート55は、その中間部が縦枠材46、47の内側面間おいて軸支され、先端部に、常時接地のホイール56が取り付けられ、後端部が縦軸杆51、52の先端部に軸着される(図5、7参照)。また、縦軸杆51、52上に軸受58、59が設置され、軸受58、59間に可動軸60が渡されて軸支される。   In addition, a wheel 56 is attached to the distal end portions of the vertical shafts 51 and 52 via a link plate 55. The link plate 55 has an intermediate portion pivotally supported between the inner side surfaces of the vertical frame members 46, 47, a normally grounding wheel 56 is attached to the front end portion, and a rear end portion is the front end of the vertical shaft 51, 52. It is pivotally attached to the part (see FIGS. 5 and 7). Further, bearings 58 and 59 are installed on the vertical shafts 51 and 52, and the movable shaft 60 is passed between the bearings 58 and 59 and supported.

かかる構成において横軸杆50が油圧シリンダー等によって上昇駆動されると、横軸杆50を介して縦枠材46、47、直角部材53、及び、縦軸杆51、52が上昇する(図7における仮想線表示部参照)。直角部材53の上昇は、その回動動作を伴う。即ち、横軸杆50が上昇するに伴い、折曲していた直角部材53の長尺辺が伸ばされて回動することになる。   In such a configuration, when the horizontal shaft rod 50 is driven up by a hydraulic cylinder or the like, the vertical frame members 46 and 47, the right-angle member 53, and the vertical shaft rods 51 and 52 are raised through the horizontal shaft rod 50 (FIG. 7). In the virtual line display section). The raising of the right-angle member 53 is accompanied by its rotation. That is, as the horizontal shaft 50 is raised, the long side of the bent right-angle member 53 is extended and rotated.

また、直角部材53が回動動作するに伴い、その短尺辺の先端が上昇しつつ前方に変位する結果、縦軸杆51、52が上昇しつつ前方に押され、縦軸杆51、52上に設置されている可動軸60も、一体となって上昇しつつ、前方に変位する。そして、縦軸杆51、52が前方に押されると、リンクプレート55がその中間枢支部57を軸に回動し、ホイール46を接地状態のまま引き寄せる(図7における仮想線表示部参照)。この動作によってタイヤ10が浮上させられ、その状態が保持される。   Further, as the right-angle member 53 rotates, the tip of the short side rises and is displaced forward. As a result, the vertical shafts 51 and 52 are pushed forward while being raised, and the vertical shafts 51 and 52 are moved upward. The movable shaft 60 installed on the upper side is also moved upward while being integrally lifted. When the vertical shafts 51 and 52 are pushed forward, the link plate 55 rotates around the intermediate pivot 57 and pulls the wheel 46 in a grounded state (see the phantom line display in FIG. 7). By this operation, the tire 10 is lifted and the state is maintained.

縦枠材46、47の一方(図示した例では縦枠47)の先端部に水平プレート61が延設され、その上に、可動ブラケット64に設置されたLMブロック63を支持するガイドレール62が敷設される(図5、図6参照)。可動ブラケット64には、縦枠材46、47の先端部間を開閉する受け軸65が取り付けられる。この受け軸65は、上記実施形態における受け軸17と同様の役割を果たすもので、この場合の受け軸65は、ガイドレール62に沿って可動ブラケット64を進退移動させることにより、縦枠材46、47の先端部間を開閉するように動作する。なお、受け軸65の進退操作は、その動きをロックするロック杆66を引き上げた後に行う。   A horizontal plate 61 extends from the tip of one of the vertical frame members 46 and 47 (vertical frame 47 in the illustrated example), and a guide rail 62 that supports the LM block 63 installed on the movable bracket 64 is provided thereon. It is laid (see FIGS. 5 and 6). The movable bracket 64 is attached with a receiving shaft 65 that opens and closes the front ends of the vertical frame members 46 and 47. The receiving shaft 65 plays a role similar to that of the receiving shaft 17 in the above-described embodiment. In this case, the receiving shaft 65 moves the movable bracket 64 forward and backward along the guide rail 62 to thereby move the vertical frame member 46. , 47 operates so as to open and close between the tip portions. The advance / retreat operation of the receiving shaft 65 is performed after the lock rod 66 that locks the movement is pulled up.

この実施形態にかかる装置によって車体のタイヤ10の1つを浮上させてその状態を保持させるには、本体41をその自走手段とハンドル操作によって所望位置に移動させ、受板65を開き、また、支持フレーム41を下げた状態にて前進させて、タイヤ10(例えば、右側前輪)を縦枠材46、47間に導入する。タイヤ10を導入した後、受板65を閉じ、ロック杆66を差し込んで受板65ロックする。   In order to float one of the tires 10 of the vehicle body and keep the state thereof by the apparatus according to this embodiment, the main body 41 is moved to a desired position by its self-propelled means and handle operation, the receiving plate 65 is opened, The tire 10 (for example, the right front wheel) is introduced between the vertical frame members 46 and 47 by moving forward with the support frame 41 lowered. After the tire 10 is introduced, the receiving plate 65 is closed, and a lock rod 66 is inserted to lock the receiving plate 65.

そして、必要に応じ、本体41を後退させて受板65をタイヤ10の周面に当接させた後、油圧シリンダー等の作用で横軸杆50を上昇させると、上述した作用により縦枠材46、47及び縦軸杆51、52が上昇し、可動軸60が上昇しつつ前進し、タイヤ10を浮上させる。このようにしてタイヤ10を浮上させた時点で、油圧シリンダー等の昇降手段の動作を停止させることにより、タイヤ10は、受板65と可動軸60とに挟持されて、その浮上状態を維持することになる。その後の操作は、上記実施形態の場合に準じて行う。   Then, if necessary, the main body 41 is retracted and the receiving plate 65 is brought into contact with the peripheral surface of the tire 10, and then the horizontal shaft rod 50 is raised by the action of a hydraulic cylinder or the like. 46 and 47 and the vertical shafts 51 and 52 rise, and the movable shaft 60 moves forward while moving up, and the tire 10 is lifted. When the tire 10 is lifted in this manner, the operation of the lifting means such as a hydraulic cylinder is stopped, so that the tire 10 is sandwiched between the receiving plate 65 and the movable shaft 60 and maintains its floating state. It will be. Subsequent operations are performed according to the above embodiment.

この発明をある程度詳細にその最も好ましい実施形態について説明してきたが、この発明の精神と範囲に反することなしに広範に異なる実施形態を構成することができることは明白である。従って、この発明は、添付請求の範囲において限定した以外はその特定の実施形態に制約されるものではない。   Although the invention has been described in some detail with its most preferred embodiments, it is evident that a wide variety of embodiments can be constructed without departing from the spirit and scope of the invention. Accordingly, the invention is not limited to that particular embodiment, except as limited in the appended claims.
