[0001] This invention relates to the field of fluid loading and unloading technology, and in particular to a hose tower-type oil delivery arm. Background Technology

[0002] Marine loading booms are specialized equipment used at port terminals to connect pipelines with ships for loading and unloading liquids. Traditional loading booms consist of a column, inner boom, outer boom, three-dimensional connector, and hydraulic control system. Structurally, the main pipeline and steel structure are separate. For some small docks, space constraints may prevent the installation of traditional loading booms. Furthermore, the fixed location of the equipment makes adjustment inconvenient, and the purchase price is high, the production cycle is long, maintenance is difficult, and there are many types of spare parts required. Summary of the Invention

[0003] The technical problem that this invention aims to solve is that current marine loading and unloading arms are not suitable for small docks, have fixed and limited installation positions, are very inconvenient to adjust, are expensive to purchase, have long production cycles, are difficult to maintain, and require a wide variety of spare parts.

[0012] The vertical tower is equipped with an internal ladder for easy climbing.

[0013] A horizontal guide pipe is fixed on the inner bottom surface of the horizontally placed electrically controlled translation seat and is fixedly connected to the inside of the bottom feed pipe. An upper electrically controlled valve is fixed on the horizontal guide pipe. The outer outlet of the upper electrically controlled valve is fixedly connected to the lateral rotary joint at the lower end of the internal thread translation adjustment seat through a flexible guide pipe.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] Figure 1 , Figure 2 and Figure 3The hose tower-type oil delivery arm shown includes a vertical tower 1, a bottom feed pipe 2 installed inside the vertical tower 1, and a hose 3 for discharging. A horizontal electrically controlled translation seat 4 is fixedly mounted on the bottom inner surface of the vertical tower 1. An internally threaded translation adjustment seat 5 is movably mounted on the horizontally threaded translation adjustment seat 4. An electrically controlled tilting telescopic inner arm 6 connected to the bottom feed pipe 2 is movably mounted on the outer surface of the internally threaded translation adjustment seat 5. An electrically controlled tilting outer arm 7 is movably mounted on one side of the top of the electrically controlled tilting telescopic inner arm 6. The feed end of the hose 3 is inserted into the outer opening of the electrically controlled tilting outer arm 7 and is fixedly connected to the inside of the electrically controlled tilting outer arm 7. An electrically controlled hose hanger 8 for controlling the hose 3 is fixedly mounted at the top of the vertical tower 1.

[0027] To facilitate internal assembly, the horizontally mounted electrically controlled sliding seat 4 includes a bottom mounting frame 41 fixedly mounted on the upper surface of the vertical tower 1, an electrically controlled adjusting screw 42 movably mounted inside the bottom mounting frame 41, a horizontally mounted guide rod 43 fixedly mounted inside the bottom mounting frame 41, and a strip-shaped transition opening at the bottom of the bottom mounting frame 41.

[0028] To facilitate translation adjustment and movable assembly, the internal thread translation adjustment seat 5 has internal thread adjustment through holes that cooperate with the electric control adjustment screw 42, a horizontal guide through hole that cooperates with the horizontal guide rod 43, and an inverted L-shaped internal liquid guide hole 51 inside the internal thread translation adjustment seat 5. The outer side of the internal thread translation adjustment seat 5 is equipped with a lateral rotary joint 52 for movable assembly of the electric control flip telescopic inner arm 6 at the opening position of the internal liquid guide hole 51.

[0029] To facilitate external tilting and telescopic movement, the electrically controlled tilting telescopic inner boom 6 includes a main tilting tube 61 that is movably connected to the outer bottom of the outer side and the lateral rotary joint 52, an external connecting seat 62 fixed on the outer side of the main tilting tube 61, a synchronous translation winch 63 mounted on the top of the vertical tower 1, an external telescopic tube 64 that is slidably inserted into the upper opening of the main tilting tube 61 through the internal telescopic tube, and an external telescopic cylinder 65 fixed on the outer side of the main tilting tube 61 for controlling the external telescopic tube 64.

[0030] Both the synchronous translation winch 63 and the external telescopic cylinder 65 are existing technologies. The synchronous translation winch 63 and the internal thread translation adjustment seat 5 move synchronously, which can ensure the structural stability and consistency of the oil delivery arm after translation adjustment. The translation adjustment principle of the synchronous translation winch 63 is the same as that of the internal thread translation adjustment seat 5, using a horizontal screw to guide and rotate the translation, while the external telescopic cylinder 65 is used to control the extension and retraction adjustment of the external telescopic pipe 64 along the main tilting pipe body 61.

[0031] To facilitate external tilting adjustment, the electrically controlled tilting boom 7 includes a tilting boom tube 72 movably connected to the upper end of one side of the external telescopic tube 64 via an upper rotary joint 71, and a drive cylinder 73 movably assembled between the external telescopic tube 64 and the tilting boom tube 72.

[0037] The electrically controlled tilting arm 862, the central electrically controlled wheel 863, and the side electrically controlled wheel 864 are all existing technologies. The electrically controlled tilting arm 862 uses arc-shaped tilting arms located on both sides of the bottom connecting frame 861 and existing lateral support rods for adjustment and tilting, which are used to clamp the hose 3 from both sides. The central electrically controlled wheel 863 and the side electrically controlled wheel 864 are used to adjust the translation of the clamped hose 3.

[0038] To facilitate climbing inside the vertical tower 1 and make it easier to adjust and maintain the control unit of the oil delivery arm, thus reducing the difficulty of operation, an internal ladder 9 is installed inside the vertical tower 1 for easy climbing.

[0039] To facilitate independent bottom control feeding, a horizontal guide pipe 10 is fixed on the inner bottom surface of the horizontally placed electrically controlled translation seat 4, which is fixedly connected to the inside of the bottom feed pipe 2. An upper electrically controlled valve 11 is fixed on the horizontally placed guide pipe 10. The outer outlet of the upper electrically controlled valve 11 is fixedly connected to the lateral rotary joint 52 at the lower end of the internal thread translation adjustment seat 5 through a flexible guide pipe 12.

[0040] The upper-mounted solenoid valve 11 is existing technology, which controls the connection state between the horizontal guide tube 10 and the flexible guide tube 12.

[0041] A steel-structured vertical tower 1 is installed on the dock. An electrically controlled hose reel 8 and a synchronously moving winch 63 are installed on the top platform of the tower 1. The oil delivery arm is mounted on the steel structure and consists of an inlet section, an internal tilting section, an external tilting section, and a hanging section, connected by three rotary joints. During operation, the synchronously moving winch 63 first lowers the inner arm. A drive cylinder 73 is installed on the internal tilting section, which pushes the outer arm to extend. The electrically controlled hose reel can extend and retract, raising and lowering, lifting the hose 2 to the ship for connection to the manifold flange. The vertical tower 1 has internal ladders 9, steps, etc., for personnel to access for maintenance. The inlet section is connected to the pipelines on the dock via a flange. Multiple oil delivery arms can be arranged on the vertical tower 1, using composite material hoses 3 for various media.
