A mining dump truck, fuel tank and anti-wave plate

Abstract

The invention discloses a fuel tank and its wave-proof plate. The wave-proof plate includes a first arched plate and a second arched plate provided with a plurality of guide holes, and the first arched plate and the second arched plate One is arched toward the front plate of the fuel tank, the other is arched toward the rear plate of the fuel tank, and the two are arranged crosswise. Compared with the existing technology, the cross-arrangement structure of the arched plates of the anti-wave plate can significantly improve the positive impact resistance. Most of the force has been converted from the vertical shear force of the straight plate scheme to the tensile and compressive stress parallel to the surface of the arched plate, which has greatly improved the force bearing of the welded seam structure. In addition, the length of the welding seam connecting the anti-wave plate and the fuel tank wall is significantly increased, and the cross-sectional area of ​​the weld seam is greatly increased. For the fuel tank, this design can improve the overall strength and stability of the structure. On this basis, the invention also discloses a mining dump truck including 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
