Background

The diagonal bracing crossbeam is an important part of the auxiliary frame of the concrete mixing transport vehicle, and the diagonal bracing crossbeam is used for connecting the auxiliary beam and the rear support, so that the structure for increasing the integral rigidity of the auxiliary frame is particularly important. At present, a diagonal bracing crossbeam structure in use is mainly formed by welding a diagonal brace vertical plate, an upper flitch and a lower flitch. This structure mainly has the following disadvantages:

(1) the vertical plate is assembled and welded with the upper and lower flitch plates, so that the welding area is large, more heat is generated, the reduction of the structure performance of the plate at a heat affected zone is easy to cause, the fatigue resistance is reduced, and the welded size is unstable and easy to deform;

(2) the inclined supporting vertical plate is of a plane structure and is welded with other pieces in a butt welding mode, so that the material utilization rate is low, the working efficiency is reduced, and the cost is increased;

(3) the welding part of the diagonal brace and the cross beam easily causes stress concentration at the cross beam of the auxiliary beam, and the auxiliary beam is likely to break after long-term use;

in view of the above disadvantages, there is a need for an improved cross-brace structure.
