Description
【０００１】[0001]
本考案は、建機等の重量物を荷台に載せる際、荷台後部を揺動により傾斜させ ることができる車両の荷台後部揺動機構に関する。 The present invention relates to a rear swinging mechanism of a vehicle, which can tilt a rear portion of the loading platform by swinging when loading a heavy load such as a construction machine on the loading platform.
【０００２】[0002]
建機等の重量物を積載する車両（トラック）においては、荷台の後部を揺動に より傾斜させることができるようになっている。たとえば図３に車両の後部を示 すように、荷台１の後部フレーム２が上下方向に揺動可能に構成されており、重 量物の積み込み、荷おろしの際、後部フレーム２が、水平位置（実線位置）から シャシーフレーム３上に支持される傾斜位置（二点鎖線の位置）まで揺動される ようになっている。後部フレーム２の後端には、導板４の一端がかけられ、導板 ４の他端は路面上に支持される。重量物は、導板４、傾斜した後部フレーム２上 を通して、荷台１の水平部分へと積載される。 In vehicles (trucks) that carry heavy loads such as construction equipment, the rear part of the cargo bed can be tilted by rocking. For example, as shown in the rear part of the vehicle in FIG. 3, the rear frame 2 of the loading platform 1 is configured to be capable of swinging in the vertical direction, and when loading or unloading heavy items, the rear frame 2 is in the horizontal position. It swings from the (solid line position) to an inclined position (position indicated by a chain double-dashed line) supported on the chassis frame 3. One end of the guide plate 4 is hooked on the rear end of the rear frame 2, and the other end of the guide plate 4 is supported on the road surface. Heavy objects are loaded on the horizontal portion of the loading platform 1 through the guide plate 4 and the inclined rear frame 2.
【０００３】[0003]
しかしながら、上記のような従来機構においては、後部フレーム２を上下に揺 動させる際には、通常、後部フレーム２と傾斜シャシーフレーム３との間に油圧 ジャツキをかませ、該油圧ジャツキを手動で操作することにより後部フレーム２ が上下に揺動される。したがって、傾斜シャシーフレーム３としては、油圧ジャ ツキ介装のために図３に示すように斜め下方に向けて相当長く延びていなければ ならず、しかも強度が要求されるため上下方向に相当肉圧のものになる。そのた め、シャシーフレーム３後端部下端と水平地面５との間の距離を大きくとること が難しい。この間の距離が小さいと、坂道等を走行する際の道路許容傾斜角度θ （図３の一点鎖線で表される角度：タイヤ６の凹みも考慮したもの）が小さく制 限される。 However, in the conventional mechanism as described above, when swinging the rear frame 2 up and down, normally, a hydraulic jack is bitten between the rear frame 2 and the inclined chassis frame 3, and the hydraulic jack is manually operated. The rear frame 2 is vertically swung by the operation. Therefore, the tilted chassis frame 3 has to extend considerably diagonally downward as shown in FIG. 3 due to the hydraulic jack interposition, and since it is required to have a sufficient strength, the tilted chassis frame 3 needs to have a considerable wall pressure in the vertical direction. It will be Therefore, it is difficult to increase the distance between the lower end of the rear end of the chassis frame 3 and the horizontal ground 5. If the distance between them is small, the road allowable inclination angle θ (the angle represented by the alternate long and short dash line in FIG. 3: taking into consideration the depression of the tire 6) when traveling on a slope or the like is limited.
【０００４】 本考案は、上記のような従来機構における問題点に着目し、傾斜時の荷台後部 を支持するシャシーフレームを小さく形成でき、かつ道路許容傾斜角度を大きく とることのできる車両の荷台後部揺動機構を提供することを目的とする。The present invention focuses on the problems in the conventional mechanism as described above, and can form a small chassis frame for supporting the rear portion of the loading platform at the time of leaning and can increase the allowable road inclination angle. An object is to provide a rocking mechanism.
【０００５】[0005]
この目的に沿う本考案の荷台後部揺動機構は、固定荷台部に対して荷台後部が 上下に揺動可能な車両において、前記揺動可能な荷台後部と固定荷台部との間に 、互に回動可能に連結された油圧シリンダと棒状部材とを設け、該油圧シリンダ の前記連結端と反対側の端部を前記荷台後部に回動可能に連結するとともに、前 記棒状部材の前記連結端と反対側の端部を前記固定荷台部に回動可能に連結し、 前記油圧シリンダのストロークを、少なくとも、荷台後部が水平位置にある時に 、前記油圧シリンダと棒状部材との連結端が着地可能なストロークとしたものか ら成る。この機構においては、荷台後部と固定荷台部との間に、固定荷台部に対 する荷台後部の姿勢、たとえば水平姿勢および所定の傾斜姿勢を固定するストッ パ機構、たとえばストッパピンを設けることが好ましい。 In order to achieve this object, a rear platform swing mechanism of the present invention is a vehicle in which the rear platform can swing up and down with respect to a fixed platform, and the rear platform and the fixed platform can swing from each other. A rotatably connected hydraulic cylinder and a rod-shaped member are provided, and an end of the hydraulic cylinder opposite to the connecting end is rotatably connected to the rear part of the cargo bed, and the connecting end of the rod-shaped member is also provided. The end on the opposite side to is rotatably connected to the fixed platform, and the stroke of the hydraulic cylinder allows the coupling end of the hydraulic cylinder and the rod-shaped member to land when at least the rear of the platform is in the horizontal position. It consists of a simple stroke. In this mechanism, it is preferable to provide a stopper mechanism, for example, a stopper pin, for fixing the posture of the rear portion of the platform with respect to the fixed platform, for example, the horizontal posture and a predetermined inclined posture, between the rear portion of the platform and the fixed platform. ..
【０００６】[0006]
このような荷台後部揺動機構においては、油圧シリンダのストローク動作によ り、油圧シリンダと棒状部材との連結端が、地面に近づく方向あるいは地面から 遠ざかる方向に移動される。そして荷台後部を水平位置から所定の傾斜位置まで 揺動させるときには、油圧シリンダは伸長され、棒状部材との連結端が着地され る。この状態で荷台後部の水平姿勢固定が解除され（たとえばストッパが解除さ れ）、油圧シリンダが縮められる。棒状部材との連結端は着地されているので、 縮ストロークにより油圧シリンダの他端は下方に移動し、それに伴って荷台後部 が下方に傾斜される。傾斜シャシーフレーム上まで傾斜させることにより、荷台 後部は所定の傾斜姿勢に保たれる。この状態で導板がかけられ、重量物等の積み おろしが行われる。 In such a rear swing mechanism of the platform, the connecting end of the hydraulic cylinder and the rod-shaped member is moved in the direction approaching the ground or moving away from the ground by the stroke operation of the hydraulic cylinder. When the rear part of the luggage platform is swung from the horizontal position to the predetermined inclined position, the hydraulic cylinder is extended and the connecting end with the rod-shaped member is landed. In this state, the horizontal posture fixation of the rear part of the luggage platform is released (for example, the stopper is released), and the hydraulic cylinder is contracted. Since the connecting end with the rod-shaped member is landed, the other end of the hydraulic cylinder moves downward due to the contraction stroke, and the rear part of the load platform is tilted downward accordingly. By tilting it up to the tilted chassis frame, the rear part of the platform is kept in a predetermined tilted posture. In this state, the guide plate is hung and heavy items are loaded and unloaded.
【０００７】 荷台後部を傾斜位置から水平位置に戻す際には、油圧シリンダは縮められる。 油圧シリンダの一端は荷台後部に、棒状部材の一端は固定荷台部に、それぞれ回 動可能に連結されており、両者は他端側で互に回動可能に連結されているので、 油圧シリンダの縮ストロークによって、荷台後部は固定荷台部に対し上方に回動 され、水平位置へと揺動される。When returning the rear part of the loading platform from the inclined position to the horizontal position, the hydraulic cylinder is contracted. One end of the hydraulic cylinder is rotatably connected to the rear part of the loading platform, one end of the rod-shaped member is rotatably connected to the fixed loading platform, and both are rotatably connected to each other on the other end side. The contraction stroke causes the rear part of the bed to pivot upward relative to the fixed bed and swing to a horizontal position.
【０００８】 荷台後部が水平位置とされているときには、油圧シリンダは縮められており、 棒状部材との連結端は上方に位置されているので、この連結端あるいは荷台後部 の後端部下端を律則とする道路許容傾斜角度は小さく保たれる。また、荷台後部 を傾斜させている際には、油圧シリンダと棒状部材との連結端は着地されている ので、該油圧シリンダと棒状部材が荷台後部に対してアウトリガーの役目も果た し、傾斜シャシーフレームの小型化が可能になる。したがって、たとえ傾斜シャ シーフレームの後端部下端が道路許容傾斜角度の律則となる場合にあっても、そ の道路許容傾斜角度は小さく保たれる。When the rear part of the loading platform is in the horizontal position, the hydraulic cylinder is contracted and the connecting end with the rod-shaped member is located above, so that the connecting end or the lower end of the rear end of the rear part of the loading platform is controlled. The allowable road inclination angle is kept small. Further, since the connecting end of the hydraulic cylinder and the rod-shaped member is landed when the rear part of the luggage platform is tilted, the hydraulic cylinder and the rod-shaped member also serve as an outrigger with respect to the rear part of the luggage platform, and the tilting is performed. The chassis frame can be downsized. Therefore, even if the lower end of the rear end of the tilt chassis frame is the law of the road allowable tilt angle, the road allowable tilt angle is kept small.
【０００９】 このように、従来機構に比べ、道路許容傾斜角度を大きくとることができ、し かも、油圧シリンダによる自動的な荷台後部の揺動（昇降）が可能となる。As described above, the road permissible inclination angle can be set larger than that of the conventional mechanism, and it is possible to automatically swing (raise and lower) the rear portion of the loading platform by the hydraulic cylinder.

A hook 24 for hooking the conducting plate as shown in FIG. 3 is provided at the rear end of the rear portion 12 of the luggage carrier.
【００１１】 荷台後部１２と固定荷台部１１との間には、本実施例では車両幅方向両側にそ れぞれ、油圧シリンダ１４と棒状部材１５が設けられている。油圧シリンダ１４ と棒状部材１５は、ピン１６を介して互に回動可能に連結されている。この連結 端部には、着地用ブラケット１７が設けられている。油圧シリンダ１４の上記連 結端と反対側の端部は、ピン１８を介して荷台後部１２に回動可能に連結されて おり、棒状部材１５の上記連結端と反対側の端部は、ピン１９を介して固定荷台 部１１に回動可能に連結されている。この油圧シリンダ１４と棒状部材１５とは 、本実施例では車両幅方向両側にそれぞれ一組づつ設けたが、車両幅方向中央部 に一組だけ設けることも可能である。また、棒状部材１５の上記連結端と反対側 の端部は、シャシーフレームに連結してもよく、強度のある固定部に回動可能に 連結されていればよい。In this embodiment, a hydraulic cylinder 14 and a bar-shaped member 15 are provided between the rear portion 12 of the platform and the fixed platform 11 on both sides in the vehicle width direction. The hydraulic cylinder 14 and the rod-shaped member 15 are rotatably connected to each other via a pin 16. A landing bracket 17 is provided at this connecting end. The end of the hydraulic cylinder 14 opposite to the connecting end is rotatably connected to the rear part 12 of the load via a pin 18, and the end of the rod-shaped member 15 opposite to the connecting end is a pin. It is rotatably connected to the fixed platform 11 via 19. In the present embodiment, the hydraulic cylinder 14 and the rod-shaped member 15 are provided on both sides in the vehicle width direction, respectively. However, it is also possible to provide only one set on the vehicle width direction central portion. Further, the end of the rod-shaped member 15 on the opposite side of the connecting end may be connected to the chassis frame, and may be rotatably connected to a strong fixing portion.
【００１２】 傾斜シャシーフレーム１３は、従来機構に比べ、大幅に短く形成されている。 荷台後部１２の横断面はコ字状に形成されており、傾斜シャシーフレーム１３を 上方から覆うように構成されている。傾斜シャシーフレーム１３には、本実施例 では、ピン孔２０、２１が２個設けられており（図２に図示）、荷台後部１２に は、１個のピン孔が設けられている。荷台後部１２が水平位置にある時には、荷 台後部１２のピン孔と傾斜シャシーフレーム１３のピン孔２０に、把手付ピン２ ２が差し込まれ、傾斜シャシーフレーム１３に対する荷台後部１２の水平姿勢を 固定し、荷台後部１２が傾斜位置にある時には、荷台後部１２のピン孔と傾斜シ ャシーフレーム１３のピン孔２１に、把手付ピン２２が差し込まれ、傾斜シャシ ーフレーム１３に対する荷台後部１２の傾斜姿勢を固定する。このピン孔２０、 ２１の個数は３個以上であってもよく、傾斜途中の位置で固定できるようにして もよい。また、この荷台後部１２の姿勢固定のためのストッパ機構は、ピンとピ ン孔との機構に限らず、適当な任意のストッパ機構を採用できる。The inclined chassis frame 13 is formed to be significantly shorter than the conventional mechanism. The cross section of the rear part 12 of the luggage platform is formed in a U shape, and is configured to cover the inclined chassis frame 13 from above. In the present embodiment, the inclined chassis frame 13 is provided with two pin holes 20 and 21 (shown in FIG. 2), and the rear portion 12 of the load platform is provided with one pin hole. When the rear part 12 of the loading platform is in the horizontal position, the pin 22 with the handle is inserted into the pin hole of the rear part 12 of the loading platform and the pin hole 20 of the inclined chassis frame 13 to fix the horizontal posture of the rear part 12 of the loading platform with respect to the inclined chassis frame 13. When the rear part 12 of the load platform is in the inclined position, the pin 22 with the handle is inserted into the pin hole of the rear part 12 of the load platform and the pin hole 21 of the inclined chassis frame 13 to fix the inclined posture of the rear part 12 of the load platform with respect to the inclined chassis frame 13. To do. The number of the pin holes 20 and 21 may be three or more, and the pin holes 20 and 21 may be fixed at a position in the middle of the inclination. Further, the stopper mechanism for fixing the posture of the rear part 12 of the loading platform is not limited to the mechanism of the pin and the pin hole, and any appropriate stopper mechanism can be adopted.
【００１３】 上記のような構造の車両の荷台後部揺動機構においては、荷台後部１２が水平 位置にある時には、油圧シリンダ１４は図１に示すように縮められ、油圧シリン ダ１４と棒状部材１５との連結端は上方に位置される。つまり、着地用ブラケッ ト１７が上方に位置される。傾斜シャシーフレーム１３が従来機構に比べ小型に 形成されており、着地用ブラケット１７が上方に位置されるので、着地用ブラケ ット１７の下端あるいは荷台後部１２の後端部下端が律則となる道路許容傾斜角 度θ（図１）は、従来機構に比べ、大きくなる。また、この時油圧シリンダ１４ をロックしておけば、荷台後部１２の姿勢固定に寄与できるので、ピン２２の負 担を軽減することも可能である。In the vehicle backside swing mechanism of the vehicle having the above-described structure, the hydraulic cylinder 14 is contracted as shown in FIG. 1 when the backside rear portion 12 is in the horizontal position, and the hydraulic cylinder 14 and the rod-shaped member 15 are provided. The connecting end with is located above. That is, the landing bracket 17 is located above. Since the inclined chassis frame 13 is formed smaller than the conventional mechanism and the landing bracket 17 is located above, the lower end of the landing bracket 17 or the lower end of the rear end of the luggage carrier rear 12 becomes a rule. The allowable road inclination angle θ (Fig. 1) is larger than that of the conventional mechanism. In addition, if the hydraulic cylinder 14 is locked at this time, it is possible to contribute to fixing the posture of the rear portion 12 of the luggage carrier, and thus it is possible to reduce the burden of the pin 22.
【００１４】 荷台後部１２が傾斜される際には、先ず、油圧シリンダ１４が、着地用ブラケ ット１７が路面２３に着地するまで伸長される。この時、少しオーバー気味に伸 長させると、ピン２２が抜きやすくなるので好ましい。そして、ピン２２を抜い た後、図２に示すように、油圧シリンダ１４が縮められ、荷台後部１２は自重で 下方に下がる。荷台後部１２が傾斜シャシーフレーム１３上の傾斜位置までくる と、油圧シリンダ１４の縮ストローク動作が停止され、ピン２２が差し込まれて 所定の傾斜姿勢に固定される。この状態でフック２４に導板が掛けられ、荷の積 おろしが行われる。油圧シリンダ１４は、傾斜した荷台後部１２に対してアウト リガーの役目も果たすので、傾斜シャシーフレーム１３への負荷は従来機構に比 べ小さくて済む。したがって、この面からも傾斜シャシーフレーム１３を小型に 形成できる。When the rear platform 12 is tilted, the hydraulic cylinder 14 is first extended until the landing bracket 17 reaches the road surface 23. At this time, it is preferable that the pin 22 is slightly overextended because the pin 22 can be easily pulled out. Then, after pulling out the pin 22, the hydraulic cylinder 14 is contracted, and the rear part 12 of the platform is lowered by its own weight, as shown in FIG. When the rear part 12 of the loading platform reaches the inclined position on the inclined chassis frame 13, the compression stroke operation of the hydraulic cylinder 14 is stopped, and the pin 22 is inserted and fixed in a predetermined inclined posture. In this state, the guide plate is hung on the hook 24 to load and unload the load. Since the hydraulic cylinder 14 also functions as an outrigger with respect to the rear portion 12 of the slanted loading platform, the load on the slanted chassis frame 13 can be smaller than that of the conventional mechanism. Therefore, the inclined chassis frame 13 can be made small from this surface as well.
【００１５】 荷台後部１２を水平位置に戻す時には、先ず、油圧シリンダ１４を少し伸ばし 、荷台後部１２を少し上げ気味にして、ピン２２を抜き、続いて油圧シリンダ１ ４が図１に示した状態まで縮められる。油圧シリンダ１４の縮ストロークに伴っ て、荷台後部１２は上方へと揺動され、図１に示した水平姿勢に戻される。この 状態で油圧シリンダ１４がロックされるとともに、ピン２２が差し込まれる。When returning the rear part 12 of the loading platform to the horizontal position, first, the hydraulic cylinder 14 is slightly extended, the rear part 12 of the loading platform is slightly raised, and the pin 22 is pulled out. Then, the hydraulic cylinder 14 is in the state shown in FIG. Can be shortened to. With the contraction stroke of the hydraulic cylinder 14, the rear part 12 of the load platform is swung upward and returned to the horizontal posture shown in FIG. In this state, the hydraulic cylinder 14 is locked and the pin 22 is inserted.
【００１６】 なお、図示を省略するが、この車両は、油圧シリンダ１４用の適当な油圧源を 備えており、配管やホースを介して必要な油圧が油圧シリンダ１４に供給される 。油圧供給の制御、操作はたとえば押釦スイッチを介して行われるようになって いる。Although not shown, this vehicle is provided with an appropriate hydraulic pressure source for the hydraulic cylinder 14, and the required hydraulic pressure is supplied to the hydraulic cylinder 14 via a pipe and a hose. The control and operation of hydraulic pressure supply are performed via, for example, a push button switch.

【考案の効果】 以上説明したように、本考案の車両の荷台後部揺動機構によるときは、油圧シ リンダと棒状部材との組合せ機構により、油圧ジャッキ等を用いることなく自動 的に荷台後部を昇降できるようにするとともに、とくに傾斜シャシーフレームを 小型に形成可能としたので、荷台後部昇降操作の容易化をはかることができると ともに、道路許容傾斜角度を大きくとることができる。As described above, in the case of the vehicle backside swinging mechanism of the present invention, the combination of the hydraulic cylinder and the rod-like member automatically moves the backside of the loading platform without using a hydraulic jack or the like. In addition to being able to move up and down, the tilted chassis frame in particular can be made smaller so that it is possible to facilitate the lifting and lowering operation of the rear part of the loading platform, and at the same time, allow a large road inclination angle.
