Lifting apparatus for submarine-atmospheric interface devices and submarine comprising the lifting apparatus

A submarine comprising:

• a hull extending longitudinally along a respective axis of extension and designed to operate underwater, below the surface of the water;
• a conning tower rising up from the top of the hull and defining a compartment for housing at least one lifting apparatus for atmospheric interface devices;
• the apparatus comprising:
• a first movable mounting unit and a second movable mounting unit each equipped at a top thereof with an interface device;
• an actuator to move the first and second movable mounting units along a main direction of movement;
• a supporting member extending along the main direction and interposed between the first movable mounting unit and the second movable mounting unit;
• the supporting member having a pair of guides, each extending along the main direction and slidably coupled to a respective one of the first and second movable mounting unit to guide the movement of the respective one of the one of the first and second movable mounting units along the main direction;
• wherein the supporting member defines a rectilinear profile with an open polygonal section.

A lifting apparatus for atmospheric interface devices in a submarine, comprising:

• a first movable mounting unit equipped at a top thereof with a first atmospheric interface device;
• a second movable mounting unit equipped at a top thereof with a second atmospheric interface device;
• a main actuator associated with the first movable mounting unit and with the second movable mounting unit to move the first and second movable mounting units along a main direction of movement;
• a supporting member extending along the main direction and interposed between the first movable mounting unit and the second movable mounting unit;
• the supporting member having a pair of guides, each extending along the main direction and slidably coupled to a respective one of the one of the first and second movable mounting units to guide the movement of the respective one of the one of the first and second movable mounting units along the main direction;
• wherein the supporting member comprises a pair of walls facing each other and spaced apart, extending principally along the main direction and connected to each other by a central partition transversal to the pair of walls;
• both of the walls being provided with a pair of lengthwise grooves located on opposite sides of each wail with respect to the central partition and each facing the corresponding groove of the other wall to at least partly define the guides.
