Description

Technical Field

[0001] The utility model relates to the technical field of loader accessories processing, in particular to a novel loader fuel tank. Background Art

[0002] As an important equipment in modern industry and logistics, the stability and durability of the fuel tank of the loader are crucial to the long-term operation and maintenance of the equipment. However, in actual use, the problem of weld cracking of the loader fuel tank is common, which not only leads to fuel leakage and wastes precious resources, but also increases maintenance costs and time.

[0003] After 500 to 2000 hours of use, the weld cracking problem of the loader fuel tank often occurs in the welds of the vertical plate installed between the fuel tank and the whole vehicle and the welds at the ladder connection. These welds are often affected by external factors such as vibration and temperature changes due to their poor stability, leading to weld cracking.

[0004] When cracks appear in welds, the usual solution is to perform a secondary repair on the welds. However, this repair method can only temporarily solve the problem. In actual operation, we found that the welds after secondary repair still crack after 300 to 500 hours of operation. This is mainly because secondary repairs often cannot completely eliminate the original stress concentration and welding defects, resulting in the inability to fundamentally improve the strength and stability of the welds. Utility Model Content

[0005] The utility model aims to provide a novel loader fuel tank with stable structure and low cost in view of the above problems.

[0006] In order to achieve the above-mentioned purpose, the utility model discloses a novel loader fuel tank, which has the structural characteristics of comprising an L-shaped positioning mounting plate and a flow partition plate fixed in the middle of the L-shaped positioning mounting plate in the vertical direction, the flow partition plate is provided with rib plates fixed to the L-shaped positioning mounting plate on both the front and rear sides, a fuel tank side plate is provided in the vertical direction and around the side edge of the L-shaped positioning mounting plate, an upper sealing plate connected to the L-shaped positioning mounting plate is provided at the upper end of the fuel tank side plate, and multiple sets of ladders are provided on the outer wall of the fuel tank side plate on the opposite side of the L-shaped positioning mounting plate.
