Description

Technical Field

[0001] This utility model relates to the field of loading and unloading arm technology, specifically to a loading and unloading arm with a gas phase pipe. Background Technology

[0002] Marine loading booms are devices used for loading and unloading cargo between docks and ships. They can smoothly transfer various transport media, such as liquids, gases, and bulk cargoes. Types of marine loading booms: Depending on the specific application, there are many types of marine loading booms, broadly categorized as oil and gas ship loading booms, chemical ship loading booms, berth-mounted ship loading booms, and long-distance transfer ship loading booms. The appropriate type of loading boom should be selected based on the specific operating conditions.

[0003] The current publication number CN221987637U discloses a loading and unloading arm with a gas phase pipe, including a boom, a forearm installed at one end of the boom, and a flange connector installed at the other end of the forearm. A connecting ring is fixedly connected to the outer wall of the forearm, and a support pipe is fixedly connected to the other end of the connecting ring. One end of the support pipe is connected to an exhaust hood, and an exhaust mechanism is connected to the inner wall of the exhaust hood. Another connecting ring is connected to the side of the exhaust hood away from the support pipe. An exhaust pipe is connected to the inner wall of this connecting ring, and the other end of the exhaust pipe is aligned with the connection point of the flange connector. The exhaust pipe is connected to the exhaust hood.

[0004] To address the leakage problem, existing technologies employ support pipes, ventilation mechanisms, and extraction pipes to absorb some of the volatile gases leaking from the flange joint. However, this approach still results in the loading and unloading arm being unable to buffer the swaying amplitude caused by tidal changes, leading to loose connections at the joint during long-term transmission.
