[0001] The utility model relates to the technical field of supporting devices, in particular to a supporting device for repairing a stern door of a roll-on / roll-off ship. Background Art

[0002] The ro-ro stern door is an important component used for loading and unloading cargo on ro-ro ships. Loading and unloading operations are usually completed through a hinged gangway. The design of the ro-ro stern door allows vehicles to easily get on and off the ship via a ramp or lifting platform, improving loading and unloading efficiency. In ship engineering, the production and installation of ro-ro stern doors must strictly comply with relevant specifications and standards.

[0003] At present, when the supporting device is in use, ships will bring a lot of mud and sand when they arrive at the port. The mud and sand may cause blockage to the lifting device, causing the device to be unable to continue upward, affecting the work progress. Therefore, staff are required to clean the lifting platform for a long time, which is time-consuming and labor-intensive, and manual cleaning is dangerous. Utility Model Content
