Abstract
La presente invención se relaciona con un bastidor de ampliación tipo escudo para la minería, comprendiendo dos patines (50) horizontales, dos brazos (20) de guía anteriores y dos brazos (30) guías posteriores que están alojados en forma pivotante en el patín (50) horizontal mediante un perno (5, 8) de pivote anterior o posterior. Cada brazo de guía posee dos tirantes (21, 31), cuyos extremos se proyectan más allá de un puente (22, 32) que conecta rígidamente los tirantes como articulaciones de horquilla inferiores y superiores. Con la finalidad de minimizar el riesgo de bloquear el brazo de quía al retraer el mecanismo de brazos de guía mediante medidas de diseño en el brazo de guía y/o el patín horizontal, al menos los puentes (22) del brazo (20) de guía anterior son dispuestos con su lado de frente (25) a una distancia de las articulaciones (23) de horquilla inferiores de los brazos (20) de guía anteriores, formando de esta manera un paso (26) vertical de roca suelta, y/o los patines (50) horizontales están provistos con unos pisos (53) inclinados para el retiro lateral de roca suelta. La invención se relaciona también con los patines horizontales.
