Abstract

Un aparato para fijar firmemente un diente de excavación reemplazable al extremo frontal do un receptáculo de excavación de equipo de excavación, donde el extremo frontal define superficies de orientación ascendentes y descendentes que convergen en una dirección delantera, el diente presenta patas superior e inferior ubicadas próximas a las superficies superior e inferior respectivas del extremo frontal, u orientadas hacia estas, donde el aparato comprende: una abertura en el extremo frontal y aberturas a través de las patas del diente el cual se superpone a la abertura y define secciones de acoplamiento del diente que cruzan la abertura y que se encuentran delante de un extremo posterior de esta; una unidad de aplicación de presión en la abertura y aberturas que se conectan a las secciones de acoplamiento adaptadas para generar y liberar una pieza de accionamiento generalmente horizontal la cual acerca recíprocamente el diente al extremo frontal; una pieza de tensión acoplada operativamente a la unidad de aplicación de presión la cual se deforma elásticamente respecto de su forma laxa cuando Ia pieza de tensión es sometida a una fuerza de accionamiento horizontal; y un espaciador configurado para ser Insertado entre la unidad de aplicación de presión y las aberturas mientras la fuerza de accionamiento horizontal deforma elásticamente la pieza de tensi6n, donde el espaciador además presenta una forma que le permite mantener la pieza de tensión en un estado de deformación flexible residual una vez reducida o detenida la fuerza de accionamiento horizontal mediante lo cual se acerca recíprocamente el extremo frontal al diente.An apparatus for firmly attaching a replaceable excavation tooth to the front end of an excavation equipment excavation receptacle, where the front end defines ascending and descending orientation surfaces converging in a forward direction, the tooth has upper and lower legs located nearby to the respective upper and lower surfaces of the front end, or oriented towards them, where the apparatus comprises: an opening in the front end and openings through the legs of the tooth which overlaps the opening and defines coupling sections of the tooth that cross the opening and that are in front of a rear end of it; a pressure application unit in the opening and openings that are connected to the coupling sections adapted to generate and release a generally horizontal drive piece which reciprocates the tooth to the front end; a tension piece operatively coupled to the pressure application unit which elastically deforms with respect to its lax shape when the tension piece is subjected to a horizontal driving force; and a spacer configured to be inserted between the pressure application unit and the openings while the horizontal actuating force elastically deforms the tension piece, where the spacer also has a shape that allows it to keep the tension piece in a deformation state flexible residual once the horizontal actuation force is reduced or stopped by means of which the front end of the tooth is reciprocally approached.
