Abstract
The invention discloses a rear door assembly of a dump truck. The rear door assembly comprises a rear door frame and a rear plate. The rear door assembly also comprises a heightened plate. The length of the heightened plate is the same with that of the rear plate, the heightened plate is fixed to the upper end of the rear plate, one side of the rear plate and one side of the heightened plate are hinged to one side of the rear door frame through laterally-opened hinges, and the other side of the rear plate and the other side of the heightened plate are locked with the rear door frame through locking assemblies in an opening-closing manner. The rear door frame comprises a floor beam and two groups of boundary beam components. The boundary beam components are perpendicular to the floor beam, each group of the boundary beam components comprises a foundation longitudinal frame beam, a heightened longitudinal frame beam and a rocker arm, the bottom ends of the foundation longitudinal frame beams are fixed to the floor beam, the top ends of the foundation longitudinal frame beams are fixedly connected with the heightened longitudinal frame beams, and the rocker arms are fixed to the ends of the heightened longitudinal frame beams. By applying the rear door assembly of the dump truck, the loading capacity of the dump truck is increased, the loaded material is prevented from scattering, the connecting ways between the rear plate and the rear door frame and between the heightened plate and the rear door frame are changed, the strength is improved, the bearing capacity is high, damage is not easily caused, the structure is simple, assembly and disassembly are convenient, and the requirement of users can be met.
