Marine large heavy-load material automatic transfer warehouse and working method thereof

The invention relates to a marine large heavy-load material automatic transfer warehouse and a working method thereof, and belongs to the technical field of transfer equipment. A tray assembly is lifted to the same height as a supporting table through a lifting assembly and then connected with a walking assembly in a transfer module, the end, making contact with the tray assembly, of the walking assembly drives a pressing rod of the tray assembly to be lifted, and the pressing rod of the tray assembly is connected with a guide column at the bottom of the tray assembly in a matched mode through a connecting rod assembly; when a pressing rod of the tray assembly is lifted, the connecting rod assembly synchronously drives a guide column at the bottom of the tray assembly to be unlocked, the tray assembly sequentially moves along the moving-out rail and the butt joint rail along with the walking assembly and then is pulled into the corresponding transfer module, the walking assembly is disengaged, and the pressin
