The invention belongs to the related technical field of ship sliding thrust bearings, and discloses a hydraulic supporting structure of a ship sliding thrust bearing. The hydraulic supporting structure of the ship sliding thrust bearing comprises a supporting ring, a piston and a limiting cover which are arranged in a thrust bearing shell; the supporting ring is a stepped cylinder, an annular groove is formed in the end face of the large end of the supporting ring, a plurality of piston cavities are formed in the bottom face of the annular groove, and the pistons are partially arranged in thepiston cavities; the limiting cover is arranged on the bottom surface of the annular groove and is provided with a through hole, and the through hole is a stepped hole and comprises a large hole and asmall hole which communicate with each other; the piston comprises a piston head, a piston rod and a piston ring connecting the piston head with the piston rod; the piston head and the piston ring are respectively arranged in a small hole and a large hole of the limiting cover; the piston rod is arranged in the piston cavity; the piston ring and the annular groove jointly form an ahead limiting structure of the piston; and the limiting cover and the piston ring jointly form a reversing limiting structure of the piston. The hydraulic supporting structure of the ship sliding thrust bearing hasthe advantages that the safety of the thrust bearing is guaranteed, the process is feasible, and the structure is simple.
