Abstract

The invention provides a mining dump vehicle frame which comprises two non-parallel longitudinal beams symmetric with respect to a longitudinal symmetric axis, wherein the head ends of the two longitudinal beams are fixedly connected through a front end beam, a tail torsion barrel is arranged between the tail ends of the two longitudinal beams, and a gantry beam is arranged between the front end beam and the tail torsion barrel in a crossing manner; the gantry beam comprises a bottom beam, a top beam is fastened on the bottom beam and comprises two supporting legs and a connecting section, the two supporting legs are supported on the top surface of the bottom beam, and the top beam and the bottom beam define a through hole; two bulge parts are formed on the top surface of the bottom beam and on the inner sides of the two supporting legs respectively, mounting grooves are formed between the two bulge parts and the corresponding supporting legs, the two longitudinal beams penetrate through the two mounting grooves respectively, and the surfaces of the longitudinal beams are welded and fixed with the bulge parts and the supporting legs respectively. According to the mining dump vehicle frame, the stress concentration and the weld seam cracking can be avoided, so that the mechanical properties of the frame, such as the bending resistance, the torsional strength and the rigidity can be remarkably improved; moreover, the mining dump vehicle frame is convenient to assemble.

Description

technical field [0001] The invention relates to heavy machinery manufacturing technology, in particular to a mining dump truck frame. Background technique [0002] Mining dump truck is a large off-road transport vehicle that mainly operates in open-pit mines, hydropower projects, civil engineering and other places. Due to its total weight, harsh working environment, and long continuous working hours, there are strict requirements on the strength and reliability of the concentrated stress-bearing parts of the vehicle; as the load-bearing base of the mining dump truck, the frame of the mining dump truck must be connected Each component of the dump truck also carries the payload from the container. Once the component is damaged during the operation of the whole vehicle, it will cause a serious accident. [0003] figure 1 It is a partial structural schematic diagram of a mining dump truck in the prior art; figure 1 As shown, the frame of the mining dump truck is composed of a...
