ANCHOR WEDGE OF COLLET CLAMP FOR REINFORCING TRIHEDRAL CROSS-SECTION ROPES Russian patent published in 2016 - IPC E04C5/12 

FIELD: construction.

SUBSTANCE: anchor wedge of a collet clamp for fixing of reinforcing ropes of a trihedral cross section has an external bearing conic surface twirled along the spiral line with the period and the direction corresponding to the step and the direction of twist of the trihedral cross-section rope, the internal working surface with a transversal generatrix in the form of a triangle and additional corrugation, flat face surfaces, and also lateral surfaces of the socket of wedges in the form of spiral line surfaces with the same direction and step of the spiral, as the internal working surface has. The lateral surfaces of the socket of wedges are located radially with reference to the longitudinal axis of the cone and at an angle of 120 degrees to each other in such a way that in each cross section along the length of the anchor wedge its internal working surface is the straight line connecting the lateral surfaces of the socket of wedges. An external bearing surface 1 of the anchor wedge is a segment of a truncated cone in the wider part of which a ring groove 2 is made. The internal working surface is a sequence of steps 3 located perpendicular to the radius which is oriented towards the centre of the step on the surface of which the cross edges 4 are made, and on the narrow side of the cone an internal conic fuzz 5 is made. Face surfaces 6 are implemented in the form of planes, perpendicular to the axis of the external bearing surface 1. Lateral surfaces of the socket of wedges 7 are implemented in the form of spiral line surfaces with a radial generatrix.

EFFECT: expansion of functional capabilities.
