Mining dump vehicle and fuel tank and swash plate thereof

Abstract

The invention discloses a fuel tank and a swash plate thereof. The swash plate comprises a first arch plate and a second arch plate, multiple flow guide holes are formed in the first arch plate and the second arch plate, either the first arch plate or the second arch plate is hunched up toward a front plate of the fuel tank, the other arch plate is hunched up toward a rear plate of the fuel tank, and the first arch plate and the second arch plate are arranged in an intersecting mode. Compared with the prior art, by means of the intersecting arrangement structure of the arch plates of the swash plate, the impact resistance in the forward direction can be remarkably improved, meanwhile, when the arch plates transmit the impact force to weld seams at connection positions of the swash plate and fuel tank walls, a majority of the acting force is transformed from the vertical shearing force of the straight plate scheme into pull and press stress in parallel along the arch plate surfaces, and force-bearing of the weld seam structure is greatly improved. In addition, the length of connection weld seams between the swash plate and the fuel tank walls is remarkably lengthened, the cross-sectional area of each weld seam is greatly increased, and for the fuel tank, by means of the design, the structural entire strength and stability can be improved. Furthermore, the invention further discloses a mining dump vehicle containing the fuel tank.

Description

technical field [0001] The invention relates to the technical field of the anti-wave plate structure of a fuel tank, in particular to a mining dump truck, a fuel tank and the anti-wave plate. Background technique [0002] The fuel tank of the mining dump truck provides guarantee for the normal and efficient operation of the vehicle with its large capacity. [0003] During the driving process of the vehicle, the impact force generated by fuel sloshing seriously affects the service life of the fuel tank structure and welded seam structure. At the same time, the size of the impact force also has a great impact on the braking of the vehicle. [0004] When the vehicle is working, due to the frequent acceleration, deceleration, braking, and starting of the vehicle, the most obvious fuel impact should be in the front and rear directions, and the larger side impact mainly occurs when the vehicle changes direction when turning. [0005] As an effective means, the anti-wave plate in...

Problems solved by technology

[0007] For a fuel tank with a large capacity and a large vertical depth, a straight anti-wave plate is installed. The anti-wave plate is subjected to the impact force of the fuel perpendicular to the plate surface, and the impact force produces a large shear force at the welding seam connecting the anti-wave plate and the fuel tank wall. At the same time, the anti-wave plate usually needs to bear the tensile stress as the tension bar between the tank wall. Therefore, under the long-term influence of this compound stress, it is bound to raise the structural form and quality of the weld at the joint between the anti-wave plate and the fuel tank wall. big challenge
