Title: Self locking coupling mechanism for engaging and moving a load

Patent ·
OSTI ID:6121018

A coupling mechanism for engaging and lifting a load has a housing with a guide passage for receiving a knob which is secured to the load through a neck of smaller diameter. A hollow ball in the housing has an opening which receives the knob and the ball is then turned to displace the opening from the housing passage and to cause the neck to enter a slot in the ball thereby securing the load to the coupling mechanism as elements of the housing block travel of the neck back into the opening when the ball is turned to the load holding orientation. As engagement of the load and locking of the coupling mechanism are accomplished simultaneously by the same ball motion, operation is simplified and reliability is greatly increased. The ball is preferably turned by a motor through worm gearing and the coupling mechanism may be controlled from a remote location. Among other uses, the coupling mechanism is adaptable to the handling of spent nuclear reactor fuel elements.
