Abstract

The invention provides a mining dump truck gantry beam and a mining dump truck frame. The mining dump truck gantry beam comprises a bottom beam; a top beam is arranged on the bottom beam in a buckled mode and comprises two supporting legs which are supported on the top surface of the bottom beam; a through hole is defined by the top beam and the bottom beam; two protruding portions are formed on the top surface of the bottom beam and the inner sides of the two supporting legs; gaps for longitudinal beams to penetrate are formed between the two protruding portions and the corresponding supporting legs. According to the mining dump truck gantry beam, the top beam can be hoisted after the bottom beam is hoisted and the longitudinal beams and the bottom beam are assembled together conveniently, then the top beam, the bottom beam and the longitudinal beams can be assembled together conveniently, and accordingly the assembly process can be greatly convenient and the machining manufacturability of the top beam and the bottom beam can be good.

Description

technical field [0001] The invention relates to heavy machinery manufacturing technology, in particular to a gantry beam of a mine dump truck and a frame of a mine dump truck. Background technique [0002] Mining dump trucks are key equipment commonly used in open-pit mining and civil construction sites. They have the characteristics of heavy load and high efficiency; due to their harsh working environment, they have high requirements for their carrying capacity; , other sub-components and goods are applied on the frame, therefore, the frame is required to have good bearing strength. [0003] The frame of the mining dump truck consists of a pair of longitudinally extending longitudinal beams and several crossbeams arranged perpendicular to the longitudinal beams, and the crossbeams and longitudinal beams are fixed together. The gantry beam is one of several beams on which the driver's cab needs to be supported and is the main force-bearing part of the frame. figure 1 It is...
