[0002] The existing aircraft suspends goods transport operation, and single-point suspension form is mostly adopted. The upper end of the steel cable is connected with the mechanical interface of the aircraft belly, and the lower end is connected with the goods through the universal sling and the hook. Before the plane takes off, the ground personnel hang the goods on the rope, and the plane transports the goods to the drop-off area according to the predetermined route and hovers at a high altitude. After the ground personnel unload the goods, the plane returns. The upper end of the sling is directly connected with the belly hanging point, and the structure is simple, but there is no corresponding active or passive suppression means for the swing of the goods during the hoisting process. The goods are affected by external environment such as sudden wind, causing the goods to swing. If the swing angle diverges and increases, it will endanger the safety of the aircraft platform and the pilot. SUMMARY

[0006] The swing prevention structure comprises a swing prevention hanger, which is a right prism structure or a circular table structure, and has a top surface and a bottom surface. The side length or diameter of the top surface is smaller than that of the bottom surface.

[0007] The suspension structure is arranged at the lower part of the swing prevention structure.

[0008] Further, the swing prevention structure further comprises a swing prevention traction rope, and the traction point of the swing prevention traction rope is evenly arranged along the periphery of the bottom surface, and the other end is connected with the aircraft. The swing prevention traction rope extends upwardly from the bottom surface.

[0009] Further, the suspension structure comprises a first sling, a second sling and a suspension rope.

[0010] The first sling is arranged at the lower middle part of the top surface, and the first sling and the second sling are connected by the suspension rope.

[0011] Further, the suspension structure further comprises a third sling and a universal hook, and the universal hook is connected to the second sling, and the third sling is hung on the universal hook.

[0012] Further, the hanging structure further comprises an automatic unhooking device; the automatic unhooking device is arranged at the lower part of the universal hook; when the object hung by the automatic unhooking device falls to the ground, the object can be automatically separated from the automatic unhooking device.

[0013] Further, the anti-swing hanger is a quadrangular prism structure.

[0014] Further, one end of the four anti-swing traction ropes is connected to the four prisms of the quadrangular prism structure, and the connection points of the anti-swing traction ropes and the prisms are closer to the bottom surface of the quadrangular prism structure.

[0015] Further, the anti-swing traction rope and the hanging rope are both Dyneema ropes.

[0016] Further, the anti-swing hanger is made of titanium alloy.

[0017] In another aspect of the utility model, a kind of aircraft is provided, comprising the aircraft hanging system.

[0018] Compared with prior art, the utility model can at least realize following beneficial effects one of:

[0019] (1) compared with prior art, the anti-swing structure of the utility model includes anti-swing hanger, the anti-swing hanger is used to connect aircraft with hanging rope, the right prism structure or circular table structure of anti-swing hanger, and the side length or diameter of top surface is less than the side length or diameter of bottom surface, so that lower end hanging rope connection point is biased up, close to the gravity point of aircraft, to reduce the influence of hanging flight process hanging load on the overturning moment of fuselage, make goods and aircraft relatively stable, improve aircraft transport safety.

[0020] (2) compared with prior art, the anti-swing structure of the utility model is further provided with anti-swing traction rope, and the anti-swing traction rope is arranged to extend obliquely upward from the edge of the bottom surface of anti-swing hanger, forms multi-directional traction force to goods, can reduce the swing of goods, makes goods and aircraft keep a relatively stable state, to avoid the influence of goods swing on aircraft flight safety. Anti-swing traction rope selects Dyneema rope, has the characteristics of light weight, high strength, good weather resistance, etc., and because the stiffness of Dyneema rope is lower than that of steel cable, the frequency of hanging system is much lower than the first-order vibration frequency of aircraft, so that the risk of vertical bounce of goods in the process of hanging transportation can be avoided.

[0021] (3) the lower end of anti-swing hanger is connected with hanging rope through first lifting ring, and hanging rope selects high-strength Dyneema rope, which has the advantages of light weight and strong weather resistance compared with steel cable; the universal hook is connected below the hanging rope, which can prevent the rotation of goods in the process of hanging flight transportation, causing the rope to twist and break, and the rotation torque to be transmitted to the aircraft to affect the normal flight control of the aircraft.

[0022] (4) The lower end of the universal hook is connected with a large-load automatic unhooking device. The automatic unhooking device is made of high-strength alloy steel. When the cargo is in the locked state, the gravity of the cargo can make the automatic unhooking device maintain the self-locking state. After the cargo touches the ground, the self-locking mechanism loses the downward pulling force, and the automatic unhooking device is automatically triggered to open the mechanism, so that the cargo is separated from the hook, thereby improving the operation efficiency, reducing the operation cost, and reducing the workload of the front-line personnel. The tension spring plays a double-redundancy protection role to prevent the self-locking mechanism from being invalid due to vibration.

[0023] (5) The main body material of the anti-swing hanger is made of high-strength titanium alloy instead of steel, which can reduce the weight of the component, increase the cargo transportation capacity, and reduce the operation cost on the basis of ensuring the structural strength.
