The invention discloses a rotating joint testing device and a testing system, belonging to the field of marine machinery. The testing device includes a base, a support platform, a wave simulation component, a rotary drive component and a limit structure. The support platform has an annular plate shape. The wave simulation component includes a plurality of hydraulic cylinders, and the rotary drivecomponent includes a slewing ring, a drive gear and a power mechanism. The slewing bearing includes a fixed ring and a movable ring. The power mechanism is disposed on the support platform. The drivegear is disposed on the power mechanism. The drive gear meshes with the teeth on the movable ring. The hydraulic cylinders can be controlled to expand and contract, and the relationship between the telescopic sequence and the length of the telescope of the multiple hydraulic cylinders changes to simulate the undulation of the waves. When testing, the rotary joint can be coaxially mounted on the movable ring, so that the rotating part of the rotary joint can be connected with the movable ring, thereby driving the drive gear to rotate through the power mechanism and enabling the rotary part andthe stationary part of the to-be-tested rotary joint to rotate relative to each other.
Description
technical field [0001] The invention relates to the field of marine machinery, in particular to a test device and a test system for a rotary joint. Background technique [0002] The single point mooring system is used as an offshore transfer terminal, which can be used for mooring and loading and unloading of crude oil by large ships. The single point mooring system usually consists of a buoy, a swivel joint arranged on the buoy and an underwater hose, and one end of the swivel joint is connected to the underwater hose. The buoy floats on the sea surface, and the tanker is connected to the other end of the swivel joint through the floating hose, so that the crude oil on the tanker can be sent to the submarine pipeline through the underwater hose, and then transported to the crude oil storage tank on the shore. [0003] The swivel joint is an important structure of the single point mooring system. The swivel joint mainly includes a stationary part and a rotating part. The s...
