The invention provides an auxiliary truck frame of a front-pushing type dump truck. A left longitudinal beam and a right longitudinal beam are welded to inner side plates and outer side plates to form a sealed box-shaped structure, two hydraulic oil cylinder supporting frame cross beams are welded to the left longitudinal beam and the right longitudinal beam respectively, a rear cross beam is welded to the rear end of the left longitudinal beam and the rear end of the right longitudinal beam, and the rear cross beam is welded to an upper rear cross beam plate and a lower rear cross beam plate to form a sealed box-shaped structure. Three middle cross beams formed by channel steel are welded to the inner side face of the left inner side plate of the left longitudinal beam and the middle section of the right inner side plate of the right longitudinal beam. A connecting plate and a rear cross beam lower supporting frame enable the auxiliary truck frame to be installed on a truck frame through bolts and nuts. The auxiliary truck frame of the front-pushing type dump truck can well adapt to installation of a front-pushing type hydraulic oil cylinder, the auxiliary truck frame and the truck frame are installed simply and conveniently, and the auxiliary truck frame of the front-pushing type dump truck is simple in structure, is easy to manufacture, and can be widely applied to the dump truck with a hydraulic oil cylinder front-pushing type lifting mechanism.
