TECHNICAL FIELD
[0001] The utility model relates to a kind of aircraft efficient loading and unhooking device of carrying. BACKGROUND
[0002] In recent years, the practical application of various small aircrafts is more and more common, especially in the transportation of small items in difficult areas, which has promoted the efficiency of transportation. However, the connection components of transportation materials and aircrafts are not mature yet. The aircrafts and materials are usually connected manually under the hovering aircraft. Once an accident occurs, the aircraft may fall. After the aircraft transports the materials to the destination, the remote control unhooking device is usually used to open, and the materials fall to the ground, which may be damaged.
[0003] Therefore, to solve the above technical problems, patent CN221541962U discloses a kind of aircraft carrying unhooking device, which realizes the rapid loading or unloading of transportation materials without landing. However, this technology also has a problem:
[0004] During remote control using the high-definition picture transmitted by the camera mounted on the aircraft, when performing loading or unloading operation, the aircraft needs to hover accurately above the carrying unhooking device. At this time, the picture transmitted by the camera shows that the hanging block below the aircraft overlaps with the carrying unhooking device and the ground. Assuming that the aircraft always hovers above the aircraft and the hanging block does not swing, the image will not change when the height of the aircraft changes. Therefore, it is difficult for the operator to accurately judge the height difference between the aircraft and the carrying unhooking device, and it is easy to fail in operation. This problem does not exist in the unloading process, because the materials fall to the ground first, and it is easy to judge the height difference between the aircraft and the carrying unhooking device after landing, and it is easy to achieve rapid unloading.
[0005] Therefore, the existing aircraft carrying unhooking device has the problem of being not conducive to operating the aircraft to perform loading. CONTENT OF THE UTILITY MODEL

[0032] In the description of the specific embodiment of the utility model, the "up" and "down" directions used in the description are determined by the scene of the utility model in most use, and in use, the aircraft is above the utility model, and the lifting cable therein is in a vertical state and is fixed to the aircraft at the upper end. The "up" and "down" directions of the directions are formed by taking the scene of the utility model in most use as a reference.
[0033] The aircraft in the utility model mainly refers to a hovering unmanned aerial vehicle.
[0034] The upper end of the lifting cable 1 of the utility model is hung on the hook below the aircraft. In the specific implementation, the lifting cable 1 can be an object with a certain length fixed below the aircraft, for example: a soft rope, a chain, a steel wire and a steel rope. Of course, the preferred example is a soft rope, which requires lower operation of the unmanned aerial vehicle.
[0035] REFERENCEFigure 1 、 Figure 2 The lower end of the lifting cable 1 has a lifting block 3. The lifting block 3 is spherical and has a certain weight, which is beneficial to rolling on the funnel and inclined plate by using gravitational potential energy. The lifting block is designed to be larger in diameter than the lifting cable, so as to hang on the lifting hole 4 and prevent the lifting cable from falling out of the lifting hole in the axial direction. In the example, the lifting block 3 is made of a steel ball.
[0036] The lifting cable is fixed below the unmanned aerial vehicle and moves with the unmanned aerial vehicle; the lifting block is fixed below the lifting cable and moves with the lifting cable. The lifting bracket of the utility model is mainly used for buckling connection and disconnection with the lifting cable.
[0037] In use, the carried goods are fixed on the lifting bracket (the specific fixing method can be various methods such as binding, welding, hooking and other methods, or other methods, or the lifting bracket is connected together by another cable, and the lifting bracket is placed beside the fixed goods).
[0038] When the lifting block is buckled with the lifting bracket, the unmanned aerial vehicle can lift the lifting bracket, and the lifting bracket can lift the carried goods through another cable.
[0039] In order to enable the lifting cable and the lifting bracket to be buckled and disconnected when the unmanned aerial vehicle is remotely operated, the structure of the lifting bracket is as follows:
[0040] Reference Figure 3 The lifting bracket has a lifting hole 4, the diameter of the lifting hole 4 is smaller than the diameter of the lifting block and larger than the diameter of the lifting cable, that is, the lifting cable can smoothly pass into the lifting hole, but the lifting block cannot pass through the lifting hole. The side of the lifting hole has a notch 11, and the lifting cable enters and exits the lifting hole from the notch 11. The notch 11 is a horn mouth, which has a large opening and is easy to make the cable smoothly enter the lifting hole from the side of the lifting hole. One example is that the lifting hole 4 is a long slot, one end of the long slot is connected to the notch, the notch is a horn mouth, the outer end of the horn mouth has a larger opening, and the lifting block 3 and the lifting cable 1 can smoothly pass through the outer end of the horn mouth.
[0041] Therefore, once the lifting block smoothly passes through the outer end of the horn mouth and falls below the lifting hole, when the lifting cable is pulled up, the lifting cable is straightened, so that the lifting cable also smoothly passes into the lifting hole from the notch, and the lifting block is stuck below the lifting hole, and the buckling of the lifting block and the lifting bracket is completed.
[0042] Reference Figures 2-4 The lifting hole is a hole opened on the lifting plate 5 and penetrates the upper and lower surfaces of the lifting plate. The lifting plate 5 is made of a metal material with certain strength, such as stainless steel sheet, high-strength lightweight aluminum alloy plate, etc.
[0043] The hanging plate 5 is arranged at an angle (so that the hanging plate has a higher side and a lower side), with the lifting hole 5 on the higher side and the notch 11 on the lower side; if the hanging block does not fall accurately into the flared opening when it falls, the angled hanging plate will help the hanging block 3 roll on the upper surface of the hanging plate towards the notch side and eventually roll into the notch 11.
[0044] Below the hanging platform is an inclined plate 8, which is arranged at an angle and in the opposite direction to the inclination of the hanging platform. That is, the side below the hanging hole is the lower side, and the side below the notch is the higher side. When the hanging block 3 rolls into the notch 11 on the upper surface of the hanging platform 5, it falls onto the upper surface of the inclined plate 8. Since the inclination direction of the inclined plate is opposite to that of the hanging platform, the hanging block rolls down below the hanging hole 4 and stops below the hanging hole 4.
[0045] One example is that the inclination angles of the ramp and the hanging plate are both 30 degrees to the horizontal plane, making it easy for the hanging block to roll.
[0046] One example is that both the hanging plate and the inclined plate are set between two vertical plates 7. The upper ends of the two vertical plates 7 are connected to the funnel 2, and the lower ends are fixed to the base 6. Then, a horizontal plate 9 is set below the inclined plate between the two vertical plates, and the lower part of the horizontal plate 9 is used to fix the lifting ring 12. In this example, it is not conducive to complete control of the lifting block.
[0047] One example is, see reference Figure 5 Both the lifting plate and the inclined plate are placed inside the limiting cylinder. All sides of the lifting plate, except for the notch, are fixed to the inner wall of the limiting cylinder. All sides of the inclined plate are completely fixed to the inner wall of the limiting cylinder, ensuring that the lifting block will not extend further downwards through the limiting cylinder after falling above the inclined plate. The limiting cylinder is longitudinally positioned and can be either a square or round tube. To facilitate the installation of a funnel above the limiting cylinder, this example prioritizes a round tube (square tubes can also be used to install funnels, but the connection is more complex). The lower edge (lower end) of the limiting cylinder is fixed to the base. Below the inclined plate inside the limiting cylinder, a horizontal plate is installed, and a lifting ring is fixed below the horizontal plate, extending from the lower outlet of the limiting cylinder.
[0048] One example is a suspension plate placed inside a limiting cylinder, with all sides of the suspension plate, except for the notch, fixed to the inner wall of the limiting cylinder; while an inclined plate seals the lower outlet of the limiting cylinder. A pair of columns are provided, with both sides of the inclined plate fixed to the columns, and the lower end of the main column fixed to the base.
[0049] One example is, see reference Figure 1 , Figure 3 , Figure 4The hanging plate 5 is arranged in the limiting cylinder 10, the hanging plate has the notch side as the front side, the opposite side of the left side as the back side, the other two sides as the left side and the right side; the left side and the right side of the hanging plate are arranged to pass through the limiting cylinder wall (the passing-through part is welded), and a pair of columns (or vertical plates 7) are arranged; the left side and the right side of the hanging plate 5 are fixed on the columns (or vertical plates 7), the hanging plate 5 is arranged between the two columns (or vertical plates 7), and the lower end of the column (or vertical plate 7) is fixed on the base. The inclined plate 8 is arranged at the lower end of the limiting cylinder 10, and the left side and the right side of the inclined plate are welded on the main column (or the vertical plate). A horizontal plate 9 is arranged between the two columns and below the inclined plate, a lifting ring 12 is arranged below the horizontal plate 9, and the lifting ring is used for fixing the carried goods. In order to reduce the weight of the hanging frame, the vertical plate 7 can be hollowed out.
[0050] In order to operate the unmanned aerial vehicle, the hanging block 3 is more easily arranged in the limiting cylinder 10 (or between the two vertical plates), a guide disc is arranged at the upper outlet of the limiting cylinder, that is, above the hanging plate, the guide disc is a funnel 2, the hanging plate corresponds to the leakage hole at the center of the funnel 2, and the upper edge of the limiting cylinder 10 is welded with the leakage hole at the center of the funnel. The taper surface of the guide disc also forms an angle of 30 degrees with the horizontal plane, so that the hanging block is easily rolled in the guide disc.
[0051] The base 6 is one of a supporting leg, a disc and a ring, and is used for contacting the ground. The base prevents the support from falling down and ensures that the funnel of the support faces upward. The lifting ring can be arranged on the base.
[0052] When the utility model is used, the mounting process is described as follows.
[0053] First, the mounting rope is connected to the carried goods, the rope head is connected to the lifting ring 12 below the hanging frame, and then the hanging frame is placed near the carried goods.
[0054] The operator controls the aircraft to be above the hanging frame, releases the lifting cable 1 on the aircraft, and makes the hanging block 3 descend.
[0055] After the hanging block 3 contacts the funnel 2 (the guide disc), the hanging block slides along the funnel 2 and rolls to the center.
[0056] After the hanging block 3 slides into the limiting cylinder 10, the hanging block can directly slide onto the inclined plate 8 or first slide onto the plane of the hanging plate 5 and then slide onto the inclined plate 8. The hanging block slides on the inclined plate and stops when contacting the inner wall of the limiting cylinder, and at this time, the lifting cable enters the notch 11.
[0057] The operator of the aircraft controls the aircraft to tighten the lifting cable 1, the hanging block 3 is clamped by the lifting hole 4, the lifting cable is continuously tightened, the hanging frame is lifted, then the carried goods is lifted, and the mounting process is completed.
[0058] When the utility model is used, the unloading process is described as follows.
[0059] The aircraft is controlled to descend, the aircraft is temporarily suspended after the transported material is landed, the cable is appropriately loosened, the aircraft is slowly flown away from the hanging hole and in the direction of the gap, and the cable is simultaneously tightened, the hanging weight is separated from the limiting cylinder, and the unloading is completed.
[0060] The hanger can also remove the base part, and the device is directly and hard connected with the material or other devices to be hung (such as a grounding trolley).
[0061] The above is an exemplary description of the utility model, and does not represent the protection range of the utility model.
