Description
【0001】[0001]
本考案は建設機械、主にパワ−ショベル等の後部に装着されるエンジンフ−ド に係り、特に容易に生産し得るようにしたエンジンフ−ドに関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine hood mounted on a rear portion of a construction machine, mainly a power shovel, and more particularly to an engine hood that can be easily manufactured.
【0002】[0002]
従来、パワ−ショベル11等の建設機械のエンジンフ−ド12は図4(a)に 平面図、図4(b)に側面図で示すような位置でフ−ド本体13の上部に設けら れているが、標準車と低騒音車とでは仕様が異なるため、それぞれ専用のフ−ド を生産していた。すなわち、従来のフ−ドは仕様が変わる毎に、図5,図6に示 すように標準車では12,騒音対策車では12′のように高さの違うものは、そ れぞれ板金を金型で曲げ成形し、溶接工程を経て製作されるようになっている。 Conventionally, an engine hood 12 of a construction machine such as a power shovel 11 is provided on an upper portion of a hood body 13 at a position as shown in a plan view of FIG. 4 (a) and a side view of FIG. 4 (b). However, because the specifications of standard vehicles and low-noise vehicles are different, they were producing their own hoods. That is, each time the specifications of the conventional hood change, as shown in Fig. 5 and Fig. 6, the standard car has 12 different heights, and the noise reduction car has 12 'different heights. Is manufactured by bending and molding it with a die.
【0003】[0003]
しかしながら仕様(高さや深さ)が異なるフ−ドをそれぞれ専用に製作してい たために生産性が劣り、かつ板金曲げと溶接の工数が大となり、コスト高となる 欠点があり、それにそれぞれ仕様毎のフ−ド曲げ型、溶接治具等の設備も必要で 段取り替えが増えて償却費が嵩み製品コスト高となる。しかもエンジン上部のア プリケ−ションの変更に対応してそれぞれのフ−ドが必要であった。 However, since the hoods with different specifications (height and depth) were specially manufactured, the productivity was poor, and the number of man-hours for bending and welding the sheet metal was large, and the cost was high. Equipment such as hood bending molds and welding jigs are also required, and the number of setup changes increases, resulting in higher depreciation costs and higher product costs. Moreover, each hood was required to accommodate changes in the application at the top of the engine.
【0004】 本考案はこれに鑑み、仕様が標準と異なり、深さの変更を必要とする場合でも 共通性をもたせて金型や治具を統一し、生産性を向上できるようにしたエンジン フ−ドを提供して従来技術の持つ欠点の解消を図ることを目的としてなされたも のである。In view of this, the present invention has a specification that is different from the standard, and even if it is necessary to change the depth, the molds and jigs are unified by providing commonality, and the engine flux is improved. -It was made with the purpose of providing the code and eliminating the drawbacks of the prior art.

上記従来技術の問題点を解決する手段として本考案は、エンジンフ−ドを蓋の ある標準フ−ドと、その標準フ−ドと積重ねできる大きさを持つ枠状のバルクフ −ドで構成し、前記標準フ−ドには下面の周囲に、バルクフ−ドには上下面の周 囲にそれぞれフランジを設けると共に、必要に応じて前記バルクフ−ドを標準フ −ドの下部に重ねてフランジ部分で接合可能としたことを特徴とする。 As a means for solving the above problems of the prior art, the present invention comprises an engine hood including a standard hood having a lid and a frame-shaped bulk hood having a size capable of being stacked with the standard hood. The standard hood is provided with flanges around the lower surface thereof, and the bulk hood is provided with upper and lower circumferential surfaces thereof, respectively, and the bulk hood is overlapped with the lower portion of the standard hood to form a flange portion. The feature is that they can be joined by.
【0006】[0006]
上記構成により、エンジンフ−ドは標準フ−ド単体、あるいは標準フ−ド+バ ルクフ−ド等と必要に応じた高さのものの使用が可能となる。 With the above construction, the engine hood can be used as a standard hood alone or as a standard hood + bulk hood having a height as required.
【0007】[0007]
図1は本考案にかかるエンジンフ−ドの標準フ−ドとバルクフ−ドの一実施例 を示す斜視図、図2は図1の標準フ−ドとバルクフ−ドを接合した場合の一実施 例を示す斜視図である。 FIG. 1 is a perspective view showing an embodiment of a standard hood and a bulk hood of an engine hood according to the present invention, and FIG. 2 is an embodiment in which the standard hood and the bulk hood of FIG. 1 are joined. It is a perspective view which shows an example.
【0008】 以下、本考案を図1,図2に示す一実施例を参照して説明する。本考案はエン ジンフ−ドを蓋1aのある標準フ−ド1と、その標準フ−ド1と積重ねできる大 きさを持つ枠状のバルクフ−ド2で構成し、前記標準フ−ド1には下面の周囲に 、バルクフ−ド2には上下面の周囲にそれぞれフランジ3,4,4を設けると共 に、必要に応じて前記バルクフ−ド2を標準フ−ド1の下部に重ねてフランジ3 部分で接合可能としたものである。The present invention will be described below with reference to an embodiment shown in FIGS. In the present invention, the engine hood comprises a standard hood 1 having a lid 1a and a frame-shaped bulk hood 2 having a size capable of being stacked with the standard hood 1, and the standard hood 1 Flanges 3, 4, and 4 are provided around the lower surface of the standard hood 1 and around the upper and lower surfaces of the bulk hood 2, respectively, and the bulk hood 2 is superposed on the lower portion of the standard hood 1 as necessary. The flange 3 can be joined together.
【0009】 一般にエンジンフ−ドはパワ−ショベルの旋回体の上に設けられる関係上、平 面積に限度があり、高さで調節しなければならないため、高さ方向にはある程度 余裕がある。したがって前記標準フ−ド1は長方形での所定高さの枠体1bで、 隅部はRとなっており、また、上部は蓋1aで枠体1bとの接続部は同じくRに 形成されている。そして枠体1bの下面の周囲にはフランジ3が一体に設けられ ている。前記バルクフ−ド2は枠体2aが標準フ−ド1の枠体1bと重なる大き さで、かつ適宜高さを有して、上下面の周囲には標準フ−ド1のフランジ3と同 じ大きさのフランジ4,4が設けられている。さらに各フランジ3,4,4面に は取付けの際に、各フランジ3,4を挟むシ−ルゴム5が設けられて、これによ り両フ−ド1,2を一体とするようになっている。図1中、6は吸気口、7は排 気口である。Generally, since the engine hood is provided on the revolving structure of the power shovel, the plane area is limited and the height must be adjusted, so that there is some margin in the height direction. Therefore, the standard hood 1 is a rectangular frame 1b having a predetermined height, the corners of which are R, the upper portion is a lid 1a, and the connecting portion with the frame 1b is also R. There is. A flange 3 is integrally provided around the lower surface of the frame 1b. The bulk hood 2 has a size such that the frame 2a overlaps the frame 1b of the standard hood 1 and has an appropriate height, and the upper and lower surfaces thereof are the same as the flange 3 of the standard hood 1. Flanges 4 and 4 of the same size are provided. Further, a seal rubber 5 for sandwiching the flanges 3 and 4 is provided on each of the flanges 3, 4 and 4 at the time of mounting, so that the both feet 1 and 2 are integrated. ing. In FIG. 1, 6 is an intake port and 7 is an exhaust port.
【0010】 つぎに作用を説明する。仕様が標準車の場合には標準フ−ド1のみが使用され 、フランジ3面は図示しないフ−ド本体のフランジ面に重ねられて、図3に示す ようなシ−ルゴム5が取付けられて結合される。つぎに仕様が超低騒音車等の場 合には吸音材、または断熱材等を内部壁面に張り付ける関係から熱が内部にこも ることになり、これを外部に放出するためにラジエ−タもより大きいものを使用 しなければならず、したがって標準フ−ド1より高いフ−ドが望まれる。このた め標準フ−ド1の外にバルクフ−ド2が必要となり、標準フ−ド1のフランジ3 の下面と、バルクフ−ド2のフランジ4の上面とを接合して一体化にした後に、 フランジ3とフランジ4(上側)とを挟むように(図3参照)シ−ルゴム5を取 付け両フランジ3,4を結合することで一体化した超低騒音車用エンジンフ−ド を得ることができる。そしてさらに高さの高いエンジンフ−ドが必要な場合には バルクフ−ド2を2段に重ねて、その上に標準フ−ド1を重ねて同様に接合する ことで一体化できる。Next, the operation will be described. When the specification is a standard vehicle, only the standard hood 1 is used, the flange 3 surface is overlapped with the flange surface of the hood body (not shown), and the seal rubber 5 as shown in FIG. 3 is attached. Be combined. Next, if the specification is for an ultra-low noise vehicle, etc., heat will be trapped inside due to the fact that a sound absorbing material or heat insulating material is attached to the inner wall surface. Must be used, and therefore a higher hood than standard hood 1 is desired. For this reason, the bulk hood 2 is required in addition to the standard hood 1, and the lower surface of the flange 3 of the standard hood 1 and the upper surface of the flange 4 of the bulk hood 2 are joined and integrated. , The flange 3 and the flange 4 (upper side) are sandwiched (see FIG. 3), the seal rubber 5 is attached, and both the flanges 3 and 4 are combined to obtain an integrated engine hood for an ultra-low noise vehicle. be able to. If a taller engine hood is required, the bulk hood 2 can be stacked in two steps, and the standard hood 1 can be stacked on the bulk hood 2 and joined in the same manner.

以上説明したように本考案は、エンジンフ−ドを蓋のある標準フ−ドと、その 標準フ−ドと積重ねできる大きさを持つ枠状のバルクフ−ドで構成し、前記標準 フ−ドには下面の周囲に、バルクフ−ドには上下面の周囲にそれぞれフランジを 設けると共に、必要に応じて前記。バルクフ−ドを標準フ−ドの下部に重ねてフ ランジ部分で接合可能としたから、仕様が異なり、高さを変える場合でも金型や 治具が統一できることで生産性が高く、コストが安くなる。つまり、仕様が変わ っても金型の取り替え作業が不要のため、早く対応できる。 As described above, according to the present invention, the engine hood is composed of a standard hood having a lid and a frame-shaped bulk hood having a size capable of being stacked with the standard hood. Flange is provided around the lower surface of the and the upper and lower surfaces of the bulk hood, respectively, and as required above. Since the bulk hood is superposed on the lower part of the standard hood and can be joined at the flange, the productivity is high and the cost is low because the molds and jigs can be unified even if the specifications are different and the height is changed. Become. In other words, even if the specifications change, there is no need to replace the mold, so we can respond quickly.
