The invention discloses a life raft frame for a ship. The life raft frame comprises a folding structure arranged on the outer side of a ship body. The folding structure comprises a pull rod and a plurality of linkage rods. And connecting pieces are rotationally connected between the pull rod and the linkage rods and between the linkage rods. A mounting plate is fixedly connected to the linkage rod, and a limiting device is arranged on the mounting plate. One side of the mounting plate is semicircular, and the semicircular side wall of the mounting plate is fixedly connected with a guide groove. According to the invention, the multiple lifesaving rafts can be released in a unified mode, the lifesaving raft releasing positions are consistent in interval, all the lifesaving rafts keep safe intervals and do not interfere with one another, and people on the ship dive and climb on the lifesaving rafts to escape conveniently; meanwhile, the releasing speed is high, the lifesaving rafts do not need to be released one by one, and therefore precious lifesaving time can be greatly saved; besides, when the deck is stored in a folded state at ordinary times, a large amount of space occupied in the horizontal direction can be saved, and the outer view of a ship body near the deck and use of the space are not affected.
