AI Technical Summary
Technical Problem
Existing mining car frames have poor resistance to bending and torsion under complex road conditions in mining areas, which easily leads to fatigue, resulting in weld cracking and affecting service life and transportation efficiency.
Method used
The front and rear frames are connected by a cable tray. The cable tray is arched, and the connecting beams are welded to the support plates. The cable tray has internal reinforcing ribs, support beams, and cantilever beams. All components are welded together to form an integral structure, which enhances the connection stability.
Benefits of technology
It improves the toughness and fatigue resistance of the frame, extends its service life, and reduces maintenance costs and safety hazards.

Abstract
High toughness anti-fatigue frame. Relates to the field of mining vehicle frame. Including front frame body and rear frame body, the front frame body is used to support the cab, the rear frame body is used to install the shovel mechanism and control the hydraulic system of the shovel mechanism, the front frame body and the rear frame body are connected through the bridge, the bridge is arched; The top of the bridge is provided with a connecting beam, the bottom of the front frame body is provided with a front supporting plate, the bottom of the rear frame body is provided with a rear supporting plate, one side of the connecting beam is welded on the top of the front supporting plate, the other side of the connecting beam extends along the top of the bridge and is welded on the top of the rear supporting plate; The front frame body and the front supporting plate, the rear frame body and the rear supporting plate, the front frame body and the bridge and the rear frame body and the bridge are all welded structures. The front frame body and the rear frame body of the application are connected through the arched bridge, which can adapt to the bending and twisting generated during the driving of the mining vehicle, and enhance the toughness and fatigue resistance of the frame.
