Description

Technical Field

[0001] This utility model relates to the field of loading and unloading arms technology, and specifically discloses an adjustable loading and unloading arm. Background Technology

[0002] Loading arms, as the name suggests, are a type of retractable and movable pipe, mainly used for loading and unloading liquids at oil and chemical terminals. The media inside the pipes are such as oil and water. Compared with the old-fashioned hoses, they have advantages such as high safety and flexibility. Loading arms are special equipment in the fluid loading and unloading process in the petrochemical industry. They use rotary joints to connect with rigid pipes and elbows to realize the transfer of liquid media between trains, tank cars and storage and transportation pipelines on trestle bridges. They replace the old-fashioned hose connections and have the characteristics of high safety, flexibility and long service life.

[0003] Chinese patent CN221459876U discloses an adjustable loading arm, including a loading arm base. An loading arm support rod is mounted on the upper end of the loading arm base, and height markings are engraved on the circumferential surface of the support rod. A first pneumatic device is mounted on the upper end of the loading arm base, and a connecting module is mounted on the upper end of the first pneumatic device. A loading arm fixing block is mounted on the circumferential surface of the support rod, and mounting holes are installed on both the upper and lower ends of the fixing block. The fixing block is installed on the circumferential surface of the support rod through the mounting holes. Therefore, when the first loading arm is retracted, the oil suction hose is simultaneously pulled out from inside the mounting ring to prevent damage to the oil suction hose. The user then re-activates the first pneumatic device to move the fixing block downwards.

[0004] The aforementioned document discloses an adjustable loading arm, which can adjust the height and horizontal position of the loading arm, but it cannot adjust the horizontal angle of the loading arm, making the adjustment inflexible. Furthermore, since it transports media through a flexible hose, it is less safe and has a shorter service life compared to rigid pipes. Therefore, an adjustable loading arm is needed to solve this problem. Utility Model Content
