Split type engineering truck frame reinforcing support

The utility model relates to the technical field of vehicle frames, in particular to a split type engineering truck frame reinforcing support. Comprising two reinforcing supports which are symmetrically installed at the lower different-face variable cross-section positions of longitudinal beams on the two sides of a vehicle frame and at the segmented positions of a vehicle body and a cargo bucket. Each reinforcing support comprises an upper flanging, a lower flanging and a protective plate, each reinforcing support is integrally in an inclined L-shaped plate shape, the L-shaped long edge of each reinforcing support clamps the lower different face of the left longitudinal beam or the lower different face of the right longitudinal beam to form the lower flanging, and the short edge opposite to the L-shaped long edge of each reinforcing support clamps the upper different face of the left longitudinal beam or the upper different face of the right longitudinal beam to form the upper flanging. The L-shaped middle p
