【発明の詳細な説明】
本発明はダンプ車輛の荷台の最大傾倒量を規制する装置
に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for regulating the maximum tilting amount of a loading platform of a dump vehicle.
ダンプ車輛の荷台は一般に一端がヒンジによって車枠に
枢支され、荷台と車枠の間に架装された油圧シリンダー
のピストンロンドの伸張により傾倒する様に構成されて
いる。Generally, one end of the loading platform of a dump vehicle is pivotally supported to the vehicle frame by a hinge, and is configured to be tilted by extension of a piston rod of a hydraulic cylinder mounted between the loading platform and the vehicle frame.
従ってピストンランドの最大伸張時に荷台は最大傾倒状
態になるものであるが、荷台の積載物を荷台の傾倒によ
り荷台外へ排出する時、最大傾倒状態に近づくと荷重の
急激な移動がみられ、ピストンロンドがもたらす荷台の
最大傾倒状態を越えて荷台が傾倒することがあり、これ
によってピストンロンドは許容最大伸張以上に伸ばされ
、油圧シリンダー（とくにヘッドカバー）が破損したり
、その他者部の摩損を早めたものである。Therefore, when the piston land is at its maximum extension, the loading platform is at its maximum tilting state, but when the load on the loading platform is discharged to the outside of the loading platform by tilting the loading platform, as the maximum tilting state is approached, a sudden shift in the load is observed. The loading platform may be tilted beyond the maximum tilting state caused by the piston rond, causing the piston rond to be extended beyond the maximum allowable extension, resulting in damage to the hydraulic cylinder (especially the head cover) and wear and tear on other parts. It was accelerated.
そこでこれを防止するため従来より荷台の最大傾倒量を
規制することが考えられ、荷台の最大傾倒時に荷台下端
部に当接して傾倒を規制するストッパーが車枠端に設け
られたものが提供された。Therefore, in order to prevent this, it has been thought to restrict the maximum tilting amount of the loading platform, and a stopper that comes into contact with the lower end of the loading platform to restrict the tilting when the loading platform is tilted to the maximum has been provided at the end of the vehicle frame. .
これによれば荷台の最大傾倒状態における荷台の下端部
下面に合せて車枠端を成型しなければならない。According to this, the end of the vehicle frame must be molded to match the lower surface of the lower end of the loading platform when the loading platform is in its maximum tilted state.
しア）シ車枠上の荷台枢支位置、ヒンジ部の長さ、油圧
シリンダー取付位置等にわずかな誤差があっても最大傾
倒時の荷台下端部位置に大きなズレが生じるから各部の
寸法誤差が許されず製作に高度な技術が要求されると共
にストッパーは車枠に一体に成型されているものである
から長期使用によるズレの調整は困難であった。A) Even if there is a slight error in the loading platform pivot position on the vehicle frame, the length of the hinge part, the hydraulic cylinder mounting position, etc., a large deviation will occur in the lower end position of the loading platform at maximum tilt, so dimensional errors in each part will occur. This was not allowed and required advanced technology to manufacture, and since the stopper was integrally molded into the vehicle frame, it was difficult to adjust for misalignment after long-term use.
又、最近、荷台と車枠間にワイヤーチェーン等の可撓索
を張設することにより、荷台の最大傾倒量を規制するこ
とも行われているが、この場合には荷台を常態にもどし
た時に可撓索が各構成部材に捲き看くおそれがあると共
に経時的に可撓索に伸び或いは歪が生じ所期の効果を奏
さない欠点があった。In addition, recently, flexible cables such as wire chains are strung between the loading platform and the vehicle frame to regulate the maximum amount of tilting of the loading platform, but in this case, when the loading platform is returned to normal There is a risk that the flexible cable may wrap around each component, and the flexible cable may stretch or become distorted over time, resulting in the disadvantage that the desired effect may not be achieved.
本発明は上述の諸点に鑑み発明されたものであって、今
、本発明の構成を一実施例を示す添附図面について詳述
すると、車枠１はシャシフレーム２とサブフレーム３か
らなり、サブフレーム３後端部に配されたヒンジ４を介
して荷台５は車枠１上に傾倒可能に枢支されている。The present invention has been invented in view of the above-mentioned points, and the structure of the present invention will now be described in detail with reference to the attached drawings showing one embodiment of the present invention. A cargo platform 5 is pivotably supported on a vehicle frame 1 via a hinge 4 disposed at the rear end of the vehicle frame 1 so as to be tiltable.
ヒンジ部は端縁部が荷台５に固設されたヒンジブラケッ
ト６と、このヒンジブラケット６に設けられた孔７に端
部が貫入した支軸８を以って構成されており、支軸８は
図示していないがサブフレーム３の軸受孔を貫通してい
る。The hinge part is composed of a hinge bracket 6 whose end edge is fixed to the loading platform 5, and a support shaft 8 whose end penetrates into a hole 7 provided in the hinge bracket 6. Although not shown, it passes through a bearing hole of the subframe 3.
ヒンジブラケット６の車輛後方側縁部に突出部材９が設
けられており、シャシフレーム２の後方側面部にはスト
ッパー１０が固設さｎている。A protruding member 9 is provided on the rear side edge of the vehicle of the hinge bracket 6, and a stopper 10 is fixedly provided on the rear side of the chassis frame 2.
そしてこのストッパー１０は荷台の最大傾倒時に突出部
材９（！＝ａ接する様に配されている。This stopper 10 is arranged so as to be in contact with the protruding member 9 (!=a) when the loading platform is tilted to its maximum.
図面（第２図）には三角形状の突出部材９と平板のスト
ッパー１０が描かれているが、この形状に限定されるも
のでない。Although the drawing (FIG. 2) shows a triangular protruding member 9 and a flat stopper 10, the shape is not limited to this.
又、ヒンジブラケット６と支軸８が固着されているもの
にあっては支軸８に突出部材を設け、これが当接するス
トッパーを車枠１に配することも可能であり、この構造
のものもヒンジ部に設けた荷台の最大傾倒量規制装置と
いいうる。In addition, in the case where the hinge bracket 6 and the support shaft 8 are fixed, it is also possible to provide a protruding member on the support shaft 8 and arrange a stopper on the vehicle frame 1 with which this comes into contact. This can be said to be a device for regulating the maximum tilting amount of the loading platform installed in the section.
一方、荷台５の傾倒は車枠１と荷台５の間に架装された
油圧シリンダー１１のピストンロッド１２の伸張によっ
て行われる。On the other hand, the loading platform 5 is tilted by extension of a piston rod 12 of a hydraulic cylinder 11 mounted between the vehicle frame 1 and the loading platform 5.
本実施例の場合、油圧シリンダ−１１端部は車枠１に枢
支されており、ピストンロッド１２端部は三角形リンク
部材１３の１つの頂部に枢着されている。In this embodiment, the end of the hydraulic cylinder 11 is pivotally supported on the vehicle frame 1, and the end of the piston rod 12 is pivotally mounted on the top of one of the triangular link members 13.
そして三角形リンク部材１３の他の頂部は荷台５（！：
、一端が車枠１に枢着された引張部材１４の他端とに夫
々枢看されている。The other top of the triangular link member 13 is the loading platform 5 (!:
, one end is pivotally connected to the other end of a tension member 14 which is pivotally connected to the vehicle frame 1.
これにより荷台５は油圧シリンダーの小さな出力をもっ
てスムーズに傾倒する。As a result, the loading platform 5 is tilted smoothly with a small output from the hydraulic cylinder.
斯様に本発明の荷台の最大傾倒量規制装置はヒンジ部に
設けられた突出部材と車枠に設けられたストッパーより
なるから構造が簡単であって製作並びに調整が容易であ
り、しかも積載物の排除における荷重の急激な移動に対
して荷台の最大傾倒量を確実に規制し、車輛各部の破損
、摩損を防止する有用な装置が提供されるものである。In this manner, the maximum tilting amount regulating device for a loading platform according to the present invention is simple in structure and easy to manufacture and adjust, since it consists of a protruding member provided on the hinge and a stopper provided on the vehicle frame. A useful device is provided that reliably controls the maximum tilting amount of the loading platform against sudden load movement during removal, and prevents damage and wear and tear on various parts of the vehicle.
