Detailed Description

The utility model is further described below with reference to the drawings and examples.

In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like indicate or are based on the orientation or positional relationship shown in the drawings, merely to facilitate description of the present utility model and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present utility model.

As shown in fig. 5 to 8, a large fuel tank assembly structure of a keel frame comprises a keel frame 1 and a fuel tank 2, wherein the relative positions of the keel frame 1 and the fuel tank 2 are configured such that the fuel tank 2 is assembled into the keel frame 1 from bottom to top along a direction forming an oblique angle with a horizontal plane. The assembly structure changes the mode that the traditional oil tank 2 is longitudinally assembled to the keel frame 1, the oil tank 2 is assembled with the keel frame 1 along the inclined direction, the limit of the keel frame 1 to the volume of the oil tank 2 is reduced, the upper and lower heights of the oil tank 2 can be further stretched, and therefore the capacity of the oil tank 2 is increased.

As shown in fig. 6, the fuel tank 2 includes a fuel tank upper case 9 and a fuel tank lower case 3 which are connected, a boundary line 4 between the fuel tank upper case 9 and the fuel tank lower case 3 includes an inclined section and a horizontal section, an inclined direction of the inclined section with respect to a horizontal plane is consistent with a direction in which the fuel tank 2 is assembled to the keel frame 1, and the horizontal section is connected to a lower end of the inclined section. The height of the tank upper shell 9 and the tank lower shell 3 are divided and balanced along the dividing line 4. The upper and lower shell welding boundary lines 4 of the oil tank 2 are adjusted from a common horizontal direction to a cutting mode with a certain inclination angle, so that the heights of the upper and lower shells of the oil tank 2 are balanced, the manufacturing process requirements are met, the assembly angle of the upper and lower shells of the oil tank 2 is equivalent to the assembly angle of the oil tank 2 and the keel frame 1, and the capacity of the oil tank 2 is increased to the maximum extent.
