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]
従来図４に示すごとく、油タンクＴの側板はコ字形に形成した側板１と２を上 下向い合せて溶接していた。この場合側板２の底部にプレ−ト３と座４を２点鎖 線で示すごとく本付けした後、側板１と２を仮付けし本溶接を行なっていた。こ の溶接により、溶接歪により図３の如く油タンクＴの下面が変形する不具合が発 生し、油タンクＴを取付ける場合、シムによって調整した後ボルトを締める必要 があった。このため取付作業性の悪さとともにボルトの弛み、取付時に発生する 応力歪による疲労寿命低下の恐れがあった。 Conventionally, as shown in FIG. 4, the side plates of the oil tank T were welded with the side plates 1 and 2 formed in a U shape facing upward and downward. In this case, after the plate 3 and the seat 4 are permanently attached to the bottom of the side plate 2 as shown by the chain double-dashed line, the side plates 1 and 2 are temporarily attached and the main welding is performed. This welding causes a problem that the lower surface of the oil tank T is deformed due to welding distortion as shown in FIG. 3, and when installing the oil tank T, it was necessary to tighten the bolt after adjusting with a shim. As a result, the mounting workability is poor, and the bolts may loosen and the fatigue life may be shortened due to the stress strain generated during mounting.
【０００３】[0003]
油タンクを機体に取付ける為の取付用ブラケットの剛性をより向上し、取付時 に発生する歪を緩和し、強度をより向上させることを目的とする。 The purpose is to further improve the rigidity of the mounting bracket for mounting the oil tank on the machine body, reduce the strain generated during mounting, and further improve the strength.
【０００４】[0004]
油タンク取付面に取付ける取付用プレ−ト３及び座４を連続形状とし、長尺の 取付用プレ−ト３及び座４による剛性アップにより、溶接時の歪を緩和するよう にした。 The mounting plate 3 and the seat 4 mounted on the mounting surface of the oil tank have a continuous shape, and the rigidity is increased by the long mounting plate 3 and the seat 4, so that the strain during welding is alleviated.
【０００５】[0005]
図５以下を参照して説明する。側板１と２の構成等、基本的には従来の構造と 同じである。本考案においては取付用プレ−ト３及び座４を従来の分割形状から 連続形状の長尺物とすることにより、プレ−ト３及び座４の剛性をアップした。 これにより側板１と２の本溶接時に発生する溶接歪を緩和することができ、座４ の平面度をより向上させることができる。上記により、取付作業性向上とともに 、ボルトの弛み及び疲労寿命の低下を防止する。 This will be described with reference to FIG. The structure of the side plates 1 and 2 is basically the same as the conventional structure. In the present invention, the rigidity of the plate 3 and the seat 4 is increased by changing the mounting plate 3 and the seat 4 from a conventional divided shape to a continuous shape. Thereby, the welding strain generated during the main welding of the side plates 1 and 2 can be relaxed, and the flatness of the seat 4 can be further improved. Due to the above, the mounting workability is improved and the slack of bolts and the reduction of fatigue life are prevented.
【０００６】[0006]
油タンクの取付面に取付ける取付用プレ−ト３及び座４を連続形状の長尺物と したので、それだけ油タンク取付部の剛性が大となり、溶接作業による歪を緩和 できるようになった。これにより取付けの作業性は向上し、ボルトの弛みや取付 時に発生する応力歪による疲労寿命の低下を防ぐことができる。 Since the mounting plate 3 and the seat 4 to be mounted on the mounting surface of the oil tank are continuous long members, the rigidity of the mounting portion of the oil tank is increased by that much, and distortion due to welding work can be alleviated. As a result, workability of mounting is improved, and it is possible to prevent the fatigue life from being shortened due to loosening of bolts and stress strain generated during mounting.
