摘要

Mechanical locking device for hydraulic actuation actuators on catenary disconnectors. It constitutes a complement to the conventional hydraulic block that the hydraulic drives (2) incorporate to ensure the interlocking of a lever (3) articulated between the output of the drive (2) itself and the respective linkage (4) through which it acts on the corresponding catenary actuator (5). The lever (3) determines a direct attack on the linkage (4). It is characterized in that an articulated attack arm (7) is included between the exit (1) and the lever (3), which in combination with the lever (3), establishes an articulated attack on the steering (4), ensuring the interlocking of the actuator (5) in its closed position.
