Description

Technical Field

[0001] This utility model relates to an anti-swaying hook device for drone lifting, belonging to the field of drone lifting technology. Background Technology

[0002] Drone hoisting operations have developed rapidly in recent years. Taking the installation of observation piers and markers for surveying control points on hillsides or in gullies as an example, each observation pier and marker typically requires 2.2 m³ of concrete (approximately 6 tons). For roadless areas of hundreds of meters, this is extremely difficult to accomplish manually. However, it can be completed by using a drone for hoisting 80 times (150 catties each time). Existing drone hoisting ropes are mostly high-strength nylon or polyester soft ropes, typically with a diameter greater than 6 mm and a length of 10 m. The top of the rope is attached to the drone hoisting frame, and the bottom of the rope is connected to a safety hook for attaching a bucket or sling.

[0003] Drones typically have a vertical takeoff and landing speed of up to 3 m / s and a horizontal flight speed of up to 13 m / s. When taking off with a suspended load, especially during horizontal flight, the load swings dramatically, posing a significant danger, particularly in confined spaces (with many trees, power lines, or communication cables nearby). Furthermore, during the drone's return flight, the rope, being too light, often lags behind the drone, floating in the air and becoming more susceptible to snagging on trees or power lines, or even tangling in the drone's rotor, potentially causing a crash. While controlling the flight attitude can mitigate the swaying, it remains less than ideal. Summary of the Invention

[0004] This invention provides a drone lifting anti-sway hook device, which can solve the problem that existing drone lifting structures are prone to vibration and swaying when lifting items.

[0005] This utility model provides a drone hoisting anti-sway hook device, the device comprising:

[0006] The hanging bracket has an axially symmetrical closed structure, with an upper connecting structure at its top and a lower connecting structure at its bottom. Both the upper and lower connecting structures are located on the axis of symmetry of the hanging bracket.

[0007] The suspension rope has one end connected to the drone's hoisting frame and the other end connected to the upper connection structure.

[0008] Two hooks are connected to the lower part of the upper and lower connecting structures respectively by suspension ropes; the hook connected to the upper connecting structure is located above the center point of the hanger.

[0009] Optionally, the upper connecting structure is a circular ring or an elliptical ring;

[0010] The lower connecting structure is a semi-circular ring or an arc.

[0011] Optionally, the length of the suspension rope is greater than the length of the hanging rope.

[0025] The present invention will now be described in detail with reference to the embodiments, but the present invention is not limited to these embodiments.

[0026] This utility model embodiment provides a drone hoisting anti-sway hook device, such as... Figures 1 to 3 As shown, the device includes:

[0027] Hanger 1 has an axially symmetrical closed structure, with an upper connecting structure 11 at its top and a lower connecting structure 12 at its bottom. Both the upper connecting structure 11 and the lower connecting structure 12 are located on the axis of symmetry of hanger 1.

[0028] The suspension rope 6 has one end connected to the hoisting frame of the drone and the other end connected to the upper connection structure 11;

[0029] Two hooks are connected to the lower part of the upper connecting structure 11 and the lower connecting structure 12 respectively by hanging ropes; the hook connected to the upper connecting structure 11 is located above the center point of the hanger 1.

[0030] This embodiment of the invention does not limit the specific shape of the hanger 1, as long as it is an axially symmetrical closed structure. For example, the hanger 1 can be an isosceles triangle, an equilateral pentagon, an equilateral hexagon, a ring, etc. Preferably, in practical applications, the hanger 1 is set as a ring, which facilitates the setting of the upper connecting structure 11 and the lower connecting structure 12, and can also achieve a better damping effect.

[0031] This embodiment of the invention does not limit the size and material of the ring-shaped bracket 1. In practical applications, the diameter of the ring-shaped bracket 1 is generally set to 1m to 2m. Preferably, the diameter is 1.5m. The bracket 1 is made of high-strength alloy material.

[0032] In this embodiment of the utility model, both the upper connecting structure 11 and the lower connecting structure 12 are integrally formed with the hanger 1.

[0033] refer to Figure 1 As shown, the hoisting rope connected to the upper connecting structure 11 is called the upper hoisting rope 4, and the hook connected to the upper hoisting rope 4 is called the upper hook 2; the hoisting rope connected to the lower connecting structure 12 is called the lower hoisting rope 5, and the hook connected to the lower hoisting rope 5 is called the lower hook 3.

[0034] In order to facilitate the connection between the upper connecting structure 11 and the lower connecting structure 12 to the suspension rope 6 and the hoisting rope, and to reduce the wear of the suspension rope 6 and the hoisting rope, in this utility model, the upper connecting structure 11 is set as a circular ring or an elliptical ring; the lower connecting structure 12 is set as a semi-circular ring or an arc.

[0035] In practical applications, the suspension rope 6 and the hanging rope are made of the same material; the length of the suspension rope 6 is greater than the length of the hanging rope. Specifically, the length of the hanging rope is 0.2m~0.5m; the length of the suspension rope 6 is 8m~9.5m. Preferably, the lengths of the upper hanging rope 4 and the lower hanging rope 5 are 0.3m; the total length of the suspension rope 6 after suspending the hanger 1 and the hook should be kept at around 10m.

[0036] In this invention, the hook is made of stainless steel. Specifically, a general-purpose safety hook can be used.

[0037] There are no restrictions on the connection method between the rope and the hook or connecting structure, as long as it can ensure the sturdiness.

[0038] This embodiment of the invention provides a relatively heavy hook device. The hook itself is heavy, which solves the problem of the suspension rope being too light when the drone is returning empty. This ensures that the suspension rope 6 and the hoisting rope are always suspended below the drone, reducing the swaying amplitude. At the same time, the double hook structure in the vertical direction can act as a damper, reducing the vibration and swaying of the hoisted object.

[0039] The hook device provided in this embodiment of the utility model consists of a ring-shaped bracket 1 and two hooks. When both hooks are suspended from the load, the load of the hook inside the ring can act as a damper, which greatly reduces the swaying amplitude during the hoisting process.

[0040] Taking the use of drones to lift strips of sand and gravel as an example, refer to Figure 2 and Figure 3 As shown, the upper load 9 and the lower load 10 (both bags of sand and gravel) are securely wrapped with the upper lifting strap 7 and the lower lifting strap 8 respectively. The two bags of sand and gravel are then suspended from the upper hook 2 and the lower hook 3 respectively, and the hoisting operation can be carried out.

[0041] After hoisting, the upper load 9 and the lower load 10 will sway as the drone accelerates and decelerates. The upper load 9 inside the ring frame 1 will have a damping effect on the hoisting device, and will swing in the opposite direction to the lower load 10 outside the ring frame 1, which will reduce the swaying amplitude and reduce safety hazards.

[0042] The principle of this utility model is simple, the problem-solving effect is significant, and it is highly operable; at the same time, the production cost of the hook is low; the hook can be used as a replacement spare part and can be installed and used as needed.

[0043] The above description is merely a few embodiments of this application and is not intended to limit this application in any way. Although this application discloses preferred embodiments as described above, it is not intended to limit this application. Any changes or modifications made by those skilled in the art without departing from the scope of the technical solution of this application using the disclosed technical content are equivalent to equivalent implementation cases and fall within the scope of the technical solution.
