Abstract

ARAÑA PARA RECIBIR BARRAS DE VENENO COMBUSTIBLE Y DISPOSITIVO DE SUJECCION Y EXTRACCION DE LAS MISMAS. LA ARAÑA DE BRAZOS HORIZONTALES (65) EN LOS QUE EXISTEN AGUJEROS (64, 72) DONDE SE ALOJAN LAS ESPIGAS (60) EN QUE TERMINAN LAS BARRAS DE VENENO (57). LAS ESPIGAS TIENEN UN TALADRO LONGITUDINAL HASTA LA MITAD DE SU LONGITUD, QUE POR ABOCARDADO POSTERIOR LAS ADAPTA, AL TOMAR LA FORMA TRONCOCONICA (62, 63, 66) AL AGUJERO DE LA ARAÑA. PARA RETIRAR LAS BARRAS, SIN NECESIDAD DE CORTE, SE INTRODUCE UN MANDRIL (70) O CONJUNTO DE ELLOS PARA QUE, POR EXTRUSION Y A TRAVES DEL TALADRO (72), SE LIBERE UNA DE LAS BARRAS O EL CONJUNTO DE LAS MISMAS.
