Abstract

Perfeccionamientos en dispositivos de arriostramiento para instalaciones de transporte y/o extracción, especialmente instalaciones cepilladoras, en explotaciones subterráneas, compuesto de cilindros de sujeción hidráulicos que arriostran la instalación de transporte y/o de extracción en su dirección longitudinal, cuyos ejes transcurren en ángulo agudo respecto al eje longitudinal de la instalación de transporte y/o extracción y que a través de articulaciones de conexión están unidos a prueba de compresión y de tracción por una parte con la instalación de transporte y/o de extracción y por otra parte con las traviesas del suelo de las unidades de entibación hidráulicas progresivas de la explotación, caracterizados porque sólo en las dos zonas extremas de la instalación de transporte y/o extracción se prevén en cada caso un grupo de cilindros de sujeción entre la instalación de transporte y/o extracción y las unidades de entibación progresivas a pasos, donde una parte de los cilindros de sujeción está inclinada en ángulo agudo respecto al eje longitudinal de la instalación de transporte y/o extracción en una dirección y la otra parte de los cilindros de sujeción lo está en dirección contraria.
