Abstract

Perfeccionamientos en útiles adicionales para dispositivos de apriete de tornillos, preferentemente de vasijas de presión de reactores, comprendiendo el dispositivo para el apriete de tornillos un anillo que se pone sobre la brida de la tapa de la vasija de presión, con disposiciones hidráulicas de cilindro y émbolo como elementos de apriete para los tornillos de la tapa de la vasija de presión, y siendo soltables y fijables, así como transportables la tuercas de fijación de los tornillos de la tapa, mediante el dispositivo de apriete de tornillos, caracterizados porque se dota a cada útil de un anillo auxiliar partido, cuyas juntas divisoras están dispuestas en la misma zona periférica que las juntas divisoras están dispuestas en la misma zona periférica que las juntas divisoras del anillo soporte, porque el anillo soporte puede ponerse sobre el anillo auxiliar y puede sujetarse con éste, y porque las partes de anillo auxiliar y puede sujetarse con éste, y porque las partes de anillo auxiliar están dotadas en cada caso de medios para el ataque de aparejos elevadores, formándose mediante los anillos sujetos, una vez sueltas las uniones de las bridas de las juntas divisoras, por lo menos dos unidades de transporte en forma de semianillo, por separado.
