How to solve the cracking problem of the four corner welds of the bottom side dump car body?

For the requirement of continuous ore loading, the vertical section of the bottom side dump car is inverted trapezoid, that is, the two ends are cantilever structures. In the design of 4m3 bottom side dump tramcar. The reinforcing rib of the bumper base only extends to half of the overhanging parts at both ends of the car body; In addition, the structure of the four corners of the trunk is relatively weak, and the four corners of the trunk are often cracked during use.

In view of this problem, the following improvements can be made to the tramcar:

1. Extend the buffer base reinforcement to the uppermost end of the trunk overhang.

2. Under the condition of ensuring that the head and tail of the two tramcars will not collide when the tramcar runs in the curve, set the reinforcing steel at the head and tail of the car to both sides of the car as far as possible to strengthen the strength of the four corners of the car.

3. The thickness of the reinforcing angle steel at the four corners on the inner side of the car body is thickened to the thickness of the mining car wallboard.
