Abstract
The utility model discloses a double tube concentric rotating joint type marine loading arm hose crane. A deck base (1) is arranged on a mother ship deck. A rotary base (3) is arranged on the deck base (1) to form a base. A rotary motor (13) is arranged on the rotary base (3) through a rotary motor support (14). A double tube concentric rotating joint (2) is arranged in the center of the rotary base (3). Double oil conveying pipes in a lazy arm (7) are connected with corresponding cabin oil conveying pumps via connecting tubes (5, 6) through the double tube concentric rotating joint (2) by a corrugated pipe and a steel hose. A sleeve (22) is sleeved outside a core barrel (17) to form two oil conveying channels. Rotation bodies (18, 19) are respectively arranged on the core barrel (17) andthe sleeve (22) to form the double tube concentric rotating joint (2). The utility model reliably converts the dynamic state of the two oil pipes in the lazy arm into the static state through the double tube concentric rotating joint. The double tube concentric rotating joint has simple structure, safety, reliability and convenient maintenance.
