Abstract

UN MEDIO DE RETENCIÓN PARA LA CONEXIÓN ENTRE UNA BROCA Y UN MANDRIL DE SUJECIÓN DE UNA HERRAMIENTA ROTATORIA, EN PARTICULAR PARA UNA DISPOSICIÓN DE TALADRO DE ROCA, MEDIANTE EL CUAL EL MANDRIL DE SUJECIÓN COMPRENDE UN PRIMER MEDIO DE RETENCIÓN Y LA BROCA COMPRENDE UN CABEZAL DE PERFORACIÓN Y UN EJE QUE COMPRENDE UN SEGUNDO MEDIO DE RETENCIÓN Y UN TERCER MEDIO DE RETENCIÓN, MEDIANTE LOS CUALES UNA CONEXIÓN ENTRE EL MANDRIL DE SUJECIÓN Y LA BROCA PUEDE SER CAMBIADA ENTRE UNA CONDICIÓN QUE PERMITE LA DESCONEXIÓN Y UNA CONDICIÓN BLOQUEADA. EL ACCIONAMIENTO DE LA HERRAMIENTA CONDUCE A LA CONEXIÓN ENTRE EL MANDRIL DE SUJECIÓN Y LA BROCA QUE ESTÁ EN LA CONDICIÓN BLOQUEADA, EN LA CUAL SE PREVIENE LA DESCONEXIÓN DEL MANDRIL Y LA BROCA, A TRAVÉS DEL PRIMER MEDIO DE RETENCIÓN QUE INTERACTÚA CON EL TERCER MEDIO DE RETENCIÓN MEDIANTE UN DESPLAZAMIENTO DE DESCONEXIÓN AXIAL DE LA BROCA.A RETAINING MEDIA FOR THE CONNECTION BETWEEN A DRILL AND A ROTATING HOLDER OF A ROTATING TOOL, IN PARTICULAR FOR A ROCK DRILLING PROVISION, BY MEANS WHICH THE CLAMPING MANDREL INCLUDES A FIRST RETAINING MEDIA AND A DRILL DRILLING AND A SHAFT THAT INCLUDES A SECOND MEANS OF RETENTION AND A THIRD MEANS OF RETENTION, THROUGH WHICH A CONNECTION BETWEEN THE CLAMP AND THE DRILL CAN BE CHANGED BETWEEN A CONDITION THAT ALLOWS THE DISCONNECTION AND A BLOCKED CONDITION. THE DRIVING OF THE TOOL LEADS TO THE CONNECTION BETWEEN THE CLAMP AND THE DRILL THAT IS IN THE BLOCKED CONDITION, IN WHICH THE DISCONNECTION OF THE MANDRIL AND THE DRILL IS PREVENTED, THROUGH THE FIRST MEANS OF RETENTION THAT INTERACT WITH THE THIRD MEDIUM OF RETENTION THROUGH A DISPLACEMENT OF AXIAL DISCONNECTION OF THE BROCA.
