Technical Field

[0001] The utility model relates to the technical field of loading and unloading boom, in particular to a quick docking mechanism for a loading and unloading boom. Background Technique

[0002] Loading and unloading refers to the physical movement form mainly based on vertical displacement. Loading and unloading is one of the main operations of logistics and is the key to determining whether the logistics can proceed smoothly. When using a loading and unloading boom, a quick docking mechanism is required. The existing patent, patent publication number CN220623117U, discloses a quick automatic docking mechanism for an LNG loading and unloading arm, including a filling arm flange. A docking component is installed on the surface of the filling arm flange, and auxiliary components are arranged on both sides of the docking component. By setting the auxiliary components in the docking component, the LNG loading and unloading arm can be assisted in locking, and when the LNG loading and unloading arm fails, it is convenient to better transport the LNG loading and unloading arm. At the same time, the sealing component set on the filling arm flange can perform auxiliary sealing treatment between the LNG loading and unloading arm and improve the sealing performance and tightness of the LNG loading and unloading arm, which is beneficial to reducing the leakage of the LNG loading and unloading arm. By setting the docking component on the filling arm flange, it is convenient to better assist in quickly and automatically docking the LNG loading and unloading arm with the ship end flange. At the same time, the protection combination set in the docking component is convenient for protecting the LNG loading and unloading arm and is beneficial to reducing the damage of the LNG loading and unloading arm during docking.
