Abstract

The invention discloses a brake device for a lifting system of a self-elevating ocean platform, and belongs to the field of ocean engineering. The brake device includes a shell, a main shaft, a driving assembly, outer friction plates and inner friction plates. One end of the shell is used for being fixedly installed on a gear box of a lifting system. The other end of the shell is used for being fixedly installed on a motor of the lifting system. The main shaft is rotatably mounted in the shell. The inner friction plates are sleeved on the outer peripheral wall of the main shaft in an axial sliding mode. the outer friction plates are inserted into the inner circumferential wall of the shell in an axial sliding mode, the outer friction plates and the inner friction plates are alternately arranged at intervals, one inner friction plate is arranged between every two adjacent outer friction plates, the driving assembly is arranged in the shell, and the driving assembly is used for driving the outer friction plates and the inner friction plates to be meshed together. When the electromagnetic brake of the self-elevating ocean platform lifting system fails, emergency braking of the self-elevating ocean platform lifting system is achieved, and the reliability of the lifting system of the self-elevating ocean platform is improved.
