Abstract
The invention concerns an annular clamping ring in particular for laying oil ducts including a rigid annular base ( ) supporting with support apparatus a coaxial ring-shaped assembly of vertical jaws ( ) mobile in the diametral planes; said apparatus includes long connecting rods ( ) articulated on the base ( ) and on the outside of the jaws ( ) in an almost vertical position, and the rigid annular body ( ) enclosing the jaw ( ) assembly, mobile in vertical translation by means of controllable cylinder actuators ( ) linking it to the base ( ); the jaws ( ) are linked with the annular body ( ) by at least two connecting rods ( ) forming an articulated parallelogram, such that the annular body ( ) vertical displacement relative to the base ( ) causes a substantially radial and synchronized displacement of the jaw assembly ( ).
