DEVICE FOR PROTECTING COUPLINGS OF COMMUNICATIONS Russian patent published in 2006 - IPC F16L37/28 F16L37/62 B64G5/00 

FIELD: couplings of the quick-acting type.

SUBSTANCE: device comprises movable casing and coupling provided with pins and clamps. The coupling is pivotally mounted on the carriage that is set in motion by means of an air-operated cylinder. The movable casing is made for permitting longitudinal and transverse movements inside the protecting structure, and the carriage is mounted separately from the casing. The casing is kinematically connected with the carriage through the rollers and is mounted on the rollers in the guides of the protecting structure. The casing is also connected with the rollers through the springs and is provided with actuator and pressing mechanism. The pressing mechanism has double-arm levers pivotally connected with the control air-operated cylinders provided with springs and drain valves. The double-arm levers are mounted in the axles of the cantilevers of the protecting structure and kinematically connected with the stop of the cantilevers and movable casing.

EFFECT: enhanced reliability.
