ABSTRACT:
Device for the remote coupling and uncoupling of two elements of great length disposed coaxially and end to end, comprising an internal actuating sleeve (14) mounted for rotation on one of the elements (1, 5) and rigidly connected to a rod (10, 67) comprising, at its end, an actuating member (12), the rotation of which enables the coupling and the uncoupling to be effected by spacing apart or release of resilient members (8, 9) assuring the junction of the two elements (1, 5). A pin (17) is disposed transversely at the end of the assembly consisting of the internal sleeve (14) and the rod (10, 67), opposite to the end carrying the actuating member (12). An external sleeve (28) of larger diameter than the diameter of the internal sleeve (14) remaining in a fixed position, whereas the two elements (1-5) are displaced in the direction of their axis, comprises slots (45, 47) in which the pin (17) can engage. A means for driving (30, 33, 35, 41, 43, 44) the external sleeve (28) in rotation enables the internal sleeve (14), the rod (10, 67) and the actuating member (12) to be caused to rotate for the coupling or uncoupling. The invention applies, in particular, the coupling of the control bars of a nuclear reactor with the control rods permitting their displacement in the core of the reactor.
