The invention discloses a mounting structure of a
stern ramp and a roll-on and roll-off platform type
barge, and relates to the technical field of ships. The mounting structure comprises a
tail end wall, a transverse auxiliary bulkhead and a plurality of longitudinal
enclosure bulkheads. The transverse auxiliary bulkhead and the multiple longitudinal
enclosure bulkheads are arranged to be matched with the
tail end wall, so that the
tail end wall, the transverse auxiliary bulkhead and the internal longitudinal
enclosure bulkheads form a whole, the strength of the mounting structure is improved, and in the using process, the situation of
structural deformation or failure caused by insufficient strength of the mounting structure is avoided; the stability of the
stern ramp is improved, the situation that the
stern ramp inclines, is blocked and even falls off is avoided, and the safety of passing vehicles and operators is improved. The roll-on and roll-off platform type
barge comprises the stern ramp, the hinge and the mounting structure, the stern ramp is connected with the mounting structure through the hinge, the situation that the stern ramp inclines, gets stuck and even falls off is avoided, and the safety of passing vehicles and operators is improved.
