AI Technical Summary

Technical Problem

The connection between the rear support components of the existing mining dump truck platform and the bracket and main beam of the frame is not tight, resulting in uneven force transmission and affecting the structural stability and service life of the vehicle.

Method used

Design a support assembly for a mining dump truck, including symmetrical first and second flat plates and a bent plate. The first and second bent plates are connected to the bracket to increase the contact area, and the rectangular fit is used to fix and transmit force to ensure that it is evenly transmitted to the main beam of the vehicle frame.

Benefits of technology

This achieves more even force distribution, improves structural stability and load-bearing capacity, and enhances vehicle safety and service life.

Abstract

The utility model is suitable for the technical field of mining dump trucks, and provides a supporting assembly of a mining dump truck, the supporting assembly comprises a bottom casting, a first surface plate and a second surface plate are symmetrically installed on the bottom casting, a first bending plate and a second bending plate are symmetrically arranged on the two sides of the first surface plate and the second surface plate, and the first bending plate and the second bending plate are symmetrically arranged on the two sides of the first surface plate and the two sides of the second surface plate. The first bent plate and the second bent plate are installed on the bottom casting, the first surface plate and the second surface plate are both in a T shape, the first surface plate comprises a first connecting part and a first installing part, the length of the first connecting part is larger than that of the first installing part, and the length of the second connecting part is larger than that of the second installing part. The first mounting part, the second mounting part, the first fixing part and the second fixing part are arranged to form a rectangle to be matched and fixed with the bottom casting, and the first connecting part, the second connecting part, the first bending part and the second bending part are matched and fixed in a rectangle, so that the effects of more uniformly transmitting pressure and improving the structural stability are achieved. The utility model further provides a supporting mechanism of the mining dump truck.
