Description
【０００１】[0001]
本考案は建設機械の油タンクの取付構造に関るものである。 The present invention relates to an oil tank mounting structure for a construction machine.
【０００２】[0002]
図１〜図３を参照して説明する。図１でＴは油タンクで、その底部に設けた取 付部で機体に取付けられる。１は断面逆ハット形をした取付用ブラケットで、図 ２に示すごとく油タンクＴの底部に対をなして溶接されている。このような構成 のため、走行時あるいは掘削等に振動外力がＺ，Ｙ，Ｘ方向に作用した場合、Ｚ 方向振動時に取付用ブラケット１のａ部又はｂ部に引張応力が発生する。又Ｙ， Ｘ方向振動時にも取付用ブラケット１のａ部又はｂ部に引張応力が発生する。さ らにａ部とｂ部には、Ｚ，Ｙ，Ｘ方向の振動外力による応力が合成されて高応力 となる為この部分に短時間で亀裂が発生し危険であった。 This will be described with reference to FIGS. In FIG. 1, T is an oil tank, which is attached to the machine body by an attachment part provided on the bottom of the oil tank. Reference numeral 1 denotes a mounting bracket having an inverted hat cross section, which is welded to the bottom of the oil tank T in pairs as shown in FIG. With such a configuration, when an external vibration force acts in the Z, Y, and X directions during traveling or excavation, tensile stress is generated in the a portion or the b portion of the mounting bracket 1 during the Z direction vibration. Further, even when vibrating in the Y and X directions, tensile stress is generated in the portion a or the portion b of the mounting bracket 1. Furthermore, since stresses due to external vibration forces in the Z, Y, and X directions are combined in parts a and b, resulting in high stress, cracks are generated in this part in a short time, which is dangerous.
【０００３】[0003]
本考案は、油タンクの取付部に発生する応力歪を緩和する構成を提供し、疲労 寿命の向上を図ることを目的とする。 It is an object of the present invention to provide a structure for relieving the stress strain generated in the mounting portion of an oil tank and improving the fatigue life.
【０００４】[0004]
油タンク取付用の断面逆ハット型をしたブラケット１の両端開口部をブラケッ ト１とタンク底部に溶接したプレ−ト２により閉塞して立体構造とした。 A bracket 1 having an inverted hat-shaped cross section for mounting an oil tank was closed at both ends with a bracket 1 and a plate 2 welded to the bottom of the tank to form a three-dimensional structure.
【０００５】[0005]
底部に設けた取付用ブラケット１の両端にプレ−ト２を溶接しブラケット１の 両端を閉塞することにより、ブラケット１が立体構成となって剛性を増し、油タ ンクＴに何れの方向の力が作用しても、強固なブラケットにより、溶接部近傍の 応力歪が緩和され、疲労寿命を一段と向上させることができる。 By welding the plates 2 to both ends of the mounting bracket 1 provided at the bottom and closing both ends of the bracket 1, the bracket 1 becomes a three-dimensional structure to increase rigidity, and force in either direction is applied to the oil tank T. Even with the action of, the strong bracket relieves the stress strain near the welded portion, and the fatigue life can be further improved.
【０００６】[0006]
図４〜図６にもとずいて説明する。この場合も油タンクＴは底部に設けた断面 逆ハット形のブラケット１を介し機体に取りつけられる。ブラケットは両側部は 従来と同様油タンクＴの底部に溶接される。さらに取付用ブラケット１の両端に プレ−ト２を取付けて塞いでいる。このプレ−ト２は図６に示す如く、側板３に 対向し、タンク底部とブラケット１の端に溶接され取付用ブラケット１の両端を これにより閉じている。 A description will be given based on FIGS. 4 to 6. In this case as well, the oil tank T is attached to the machine body through the bracket 1 having a reverse hat cross section provided at the bottom. Both sides of the bracket are welded to the bottom of the oil tank T as in the conventional case. Further, plates 2 are attached to both ends of the mounting bracket 1 to close them. As shown in FIG. 6, the plate 2 faces the side plate 3 and is welded to the bottom of the tank and the end of the bracket 1 to close both ends of the mounting bracket 1.
【０００７】[0007]
以上の如く、底部に設けた取付用ブラケット１の両端にプレ−ト２を溶接しブ ラケット１の両端を閉塞した。このようにプレ−ト２で閉塞することにより、ブ ラケット１が立体構成となって剛性を増し、油タンクＴにＸ，Ｙ，Ｚの何れの方 向の力が作用しても、強固なブラケットにより、図３に示したような溶接部近傍 の応力歪が緩和され、疲労寿命を一段と向上させることができる。 As described above, the plates 2 were welded to both ends of the mounting bracket 1 provided at the bottom to close both ends of the bracket 1. By closing the plate 2 in this manner, the bracket 1 becomes a three-dimensional structure to increase the rigidity, and even if a force in any of X, Y, and Z directions acts on the oil tank T, it is firm. With the bracket, stress strain near the welded portion as shown in FIG. 3 is relaxed, and the fatigue life can be further improved.
