[0002] In the construction of dangerous rock mass treatment on the slopes of some hydropower stations, the project involves concrete pouring, scaffolding construction, and protective net construction. However, since the construction location is located at a high altitude, high slope, and high edge, the traffic conditions on the construction site are poor. Therefore, it is impossible to use traditional transportation tools or equipment to accurately transport construction materials and small machines to the construction site. For this reason, drone lifting is used as the main equipment for material transportation. When drones are used as the main transportation equipment, in order to ensure the safety of material lifting and construction personnel and reduce construction safety risks, a separate hook needs to be designed as a tool for material lifting. Therefore, this application designs a drone hook device to solve the problems of material lifting and personnel safety. Utility Model Content

[0020] The following will be combined with the drawings of the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] This embodiment provides a UAV hook device, such as Figure 1 As shown, the drone hook device includes a drone body 1, a fixed frame 2 is fixedly connected to the bottom of the drone body 1, and the fixed frame 2 is connected to the hook device 6 via a connecting rope.

[0022] like Figure 2 As shown, the four corners of the outer surface of the drone body 1 are fixedly connected with a cantilever 12, and one side of the upper surface of the cantilever 12 is fixedly connected with a wing 13. The wing 13 is installed through the cantilever 12, and the wing 13 provides power for the drone body 1 to take off. A mounting block 14 is fixedly connected to the middle of the front of the drone body 1, and a camera 15 is provided in the middle of the front of the mounting block 14. The camera 15 facilitates the operator to observe the situation when the drone is operating at a long distance, and control the drone to take off, land, unload, and other operations. It should be noted that the drone body in this embodiment can be a finished drone device with a camera purchased as a whole on the market, and its load capacity must be able to meet the use requirements.

[0023] like Figure 1 and Figure 3 As shown, the functions of the fixed frame 2 in this embodiment are: first, as a connector connecting the rope and the drone body 1; second, as the landing gear of the drone body 1. Therefore, the fixed frame 2 in this embodiment is made of a metal pipe with light weight and high strength as a whole. Connecting rods 8 are fixedly connected to both sides of the fixed frame 2, and drone brackets 9 are fixedly connected to both sides of the bottom of the fixed frame 2; in order to ensure the connection strength between the fixed frame 2 and the drone body 1, a reinforcing rib 7 is fixedly connected to the middle part of the upper surface of the fixed frame 2. The reinforcing rib 7 is used to strengthen the stability between the fixed frame 2 and the drone body 1, strengthen the supporting effect of the device, and increase the weight of the hanging object. When the drone lands, the drone bracket 9 provides support for the drone to enable it to land stably.

[0024] like Figure 1As shown, the connecting rope in this embodiment, which serves as a connecting piece between the fixed frame 2 and the hook device 6, includes a first connecting rope 3, a cable tie 4, and a second connecting rope 5. Among them, a plurality of first connecting ropes 3 are fixedly connected inside the fixed frame 2, the other end of the first connecting rope 3 is fixedly connected to the cable tie 4, the middle of the lower surface of the cable tie 4 is fixedly connected to the second connecting rope 5, and the other end of the second connecting rope 5 is fixedly connected to the hook device 6. Further, as a preferred technical solution of this embodiment, as Figure 2 and Figure 4 As shown, a fixing ring 10 is sleeved on the outer surface of the top of the first connecting rope 3, and a connecting plate 11 is fixedly connected to one side of the fixing ring 10. The first connecting ropes 3 are connected by the fixing ring 10 and the connecting plate 11, so that the force can be more uniform.

[0025] like Figure 1 and Figure 5 As shown, the hook device 6 in this embodiment includes an anchor ring 601 for connecting with the second connecting rope 5, and a first fixing bolt 602 is fixedly connected to the bottom of the anchor ring 601, and a first side plate 603 and a second side plate 604 are fixedly connected to both sides of the first fixing bolt 602. A second fixing bolt 605 is fixedly connected to the bottom of the front of the first side plate 603, and a hook head 606 is rotatably mounted on the outer surface of the second fixing bolt 605. The spacing between the first side plate 603 and the second side plate 604 is greater than the thickness of the hook head 606, so that the hook head 606 can rotate between the first side plate 603 and the second side plate 604. Rivets 607 are fixedly connected to both sides of the middle of the front of the first side plate 603, and matching holes 608 are opened on both sides of the middle of the front of the second side plate 604, and the rivets 607 are matched with the matching holes 608.

[0026] The hook device 6 is fixedly installed on the drone body 1 through the first connecting rope 3 and the second connecting rope 5, and then the object is hung on the hook head 606, and the object is accurately lifted to the construction site by the drone. The various mechanisms installed on the hook device 6 are connected and fixed with the first side plate 603 and the second side plate 604 through the first fixing bolt 602, and the second fixing bolt 605 is installed on the hook head 606, and fixed between the second fixing bolt 605 and the side plate. The weight of the hook body end of the hook head 606 is less than the weight of the other end, forming a top-heavy design, thereby achieving automatic unhooking.

[0027] The working principle of the drone hook device is as follows:

[0028] The hook device 6 is fixedly installed on the drone body 1 through the first connecting rope 3 and the second connecting rope 5; then the object is hung on the hook head 606, and the object is accurately lifted to the specified position by the drone, and the drone body 1 is controlled to descend the flight altitude; when the object touches the ground, since the hook head 606 is designed to be top-heavy, the object is automatically unhooked after touching the ground.

[0029] After the drone unloads the load, it returns and lands. The drone bracket 9 provides support for the drone when it lands, allowing it to land stably. During the lifting process, the reinforcing ribs 7 strengthen the stability between the fixed frame 2 and the drone body 1, and strengthen the supporting effect of the device. The connecting rod 8 is adapted to the first connecting rope 3, and the first connecting rope 3 is dispersed into multiple strands through the connecting rod 8, so that the weight of the load is evenly distributed to each part of the drone body 1, so that it can lift the load more effectively and improve the lifting stability. The first connecting ropes 3 are connected by the fixing ring 10 and the connecting plate 11, so that the force can be more uniform. During the lifting process, the camera 15 is used to facilitate the operator to observe the situation when the drone is operating at a long distance, and control the drone to perform operations such as takeoff, landing and unloading.

[0030] The utility model may also have various changes and improvements, which all fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
