Automatic lock for telescoping joint of a riser system
An automatic locking mechanism for a telescoping joint for a riser functions in several modes. In an operating mode, the joint is free to have its inner and outer barrels (12, 14) move with respect to each other without engaging each other in a locking relationship. In a second position, the telesco...

| description | An automatic locking mechanism for a telescoping joint for a riser functions in several modes. In an operating mode, the joint is free to have its inner and outer barrels (12, 14) move with respect to each other without engaging each other in a locking relationship. In a second position, the telescoping joint locks when it is fully retracted. In a third position, the system locks the inner and outer barrels (12, 14) together to hold them in a fixed position. The inner and outer barrels (12, 14) are locked when a movable sleeve (30) is properly positioned to allow spring-loaded dogs (28) to be biased through windows (32) in the sleeve (30) so as to act as a landing shoulder to catch a groove (20) on the outer barrel (12). By putting the actuating sleeve (30) in a variety of positions, the various modes of the locking assembly can be deployed. |
