Description

本発明は、作動油又は燃料等を貯蔵する貯油タンク、及びその製造方法に関する。   The present invention relates to an oil storage tank that stores hydraulic oil or fuel, and a manufacturing method thereof.

車両(作業車両や建設機械等)の作動油又は燃料を貯蔵する貯油タンクは長期間無給油での作動を可能とするために、一般的に大容量のものが使用されている。建設機械で使用される貯油タンクとしては、例えば非特許文献1に記載されており、図8に示すように、貯油タンク50は板金溶接構造で、内部に油(燃料、作動油等)の揺動を抑制する仕切板51が溶接等で接合されている。また、図示していないが、一般的に、大型のタンクの剛性を高くするために、前記仕切板51の他にも補強部材をタンク側板間に溶接等で接合しているものも多い。   The oil storage tank for storing hydraulic oil or fuel of a vehicle (work vehicle, construction machine, etc.) generally has a large capacity so that it can operate without oil for a long period of time. As an oil storage tank used in a construction machine, for example, it is described in Non-Patent Document 1. As shown in FIG. 8, the oil storage tank 50 has a sheet metal welded structure, and oil (fuel, hydraulic oil, etc.) is shaken inside. A partition plate 51 that suppresses movement is joined by welding or the like. Although not shown, in general, in order to increase the rigidity of a large tank, in addition to the partition plate 51, a reinforcing member is often joined between the tank side plates by welding or the like.

発明協会公開技報、「公技番号92−16125」、発行日1992.7.15、(第2図)Japan Society for Invention and Innovation, "Public Technical Number 92-16125", Issue Date 1992.7.15 (Fig. 2)

しかしながら、上述した従来の貯油タンク50の構造では、タンク内部の狭い空間で仕切板51や補強部材の溶接作業をしなければならないので、溶接がやり難く、熟練者でも品質を保持するために困難な溶接作業を強いられている。さらに、建設機械では、貯油タンク50内に給油する際に、短時間で給油するためにクイックチャージと呼ばれる作業が通常良く行われており、このクイックチャージを行うと貯油タンク50の内圧が高くなるので、内部の溶接部の強度が非常に重要な問題となっており、上記の仕切板51や補強部材の溶接箇所も十分な強度を必要としている。このため、溶接に要する時間が長くかかり、製造コストが高くなり、また溶接品質の維持が困難である。   However, in the structure of the conventional oil storage tank 50 described above, since the partition plate 51 and the reinforcing member must be welded in a narrow space inside the tank, it is difficult to perform welding, and it is difficult for even a skilled person to maintain the quality. We are forced to do the welding work. Furthermore, in construction machines, when the oil is supplied into the oil storage tank 50, an operation called quick charge is usually performed in order to supply the oil in a short time. When this quick charge is performed, the internal pressure of the oil storage tank 50 is increased. Therefore, the strength of the internal welded portion is a very important problem, and the welded portions of the partition plate 51 and the reinforcing member also require sufficient strength. For this reason, it takes a long time for welding, the manufacturing cost becomes high, and it is difficult to maintain the welding quality.
