The invention discloses a road door retainer and a box ship, and belongs to the technical field of ships. The road door protective ring comprises a protective fence which comprises a first protective section, a second protective section and a third protective section, a protective space is defined by the first protective section, the second protective section and the third protective section, and the area of the protective space is larger than that of the road door hole. The fixing clamp is arranged at the end, away from the first protection section, of the second protection section, the fixing clamp is arranged at the end, away from the first protection section, of the third protection section, the fixing clamp comprises a first clamping plate, a connecting plate and a second clamping plate which are sequentially connected, and a U-shaped clamping space is defined by the first clamping plate, the connecting plate and the second clamping plate. Threaded holes are formed in the first clamping plate and/or the second clamping plate in a penetrating mode in the thickness direction of the first clamping plate and/or the second clamping plate. And a screw rod part of the fastener is connected with the threaded hole and extends out relative to the threaded hole to abut against the reinforcing plate. Operators are prevented from falling into a door hole, and the use safety level of the box ship is improved.
