Description

Technical Field

[0001] This utility model belongs to the field of drone accessory technology, specifically relating to a hook that can remotely control and throw cargo. Background Technology

[0002] With the rapid development of drone technology, drones are widely used in fields such as agricultural plant protection, power line inspection, fire rescue, forest protection, and outdoor transportation.

[0003] When operating drones, it is necessary to use ropes or slings to carry the corresponding materials and then lift and transport them. Due to the complex and changeable outdoor operating environment, the ropes are easily tangled in obstacles such as tree branches during the lifting and transportation process, which can cause the drone to be unable to get out of trouble.

[0004] In existing technologies, the lifting and unhooking servo motors used in drones directly clamp the cargo below, resulting in weak load-bearing capacity. If a drone gets caught on a rope during operation, it usually requires a long trek to the work site for manual unhooking, which is not only time-consuming, labor-intensive, and inefficient, but also poses safety hazards due to the high position of the entanglement and the lack of remote cargo weight display capabilities, making the drone prone to crashing due to overloading. Utility Model Content

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing a hook for remotely controlling the throwing of goods, including a housing and a weighing sensor. A first pin is movably connected through the front surface of the housing, and a second pin is movably connected through the front surface of the housing. An electric push cylinder is movably connected to the side surface of the first pin. An installation block is fixedly connected to the output end of the electric push cylinder. A push cylinder connector plate is symmetrically movably connected to the side surface of the installation block. A connecting rod is symmetrically movably connected to the side surface of the push cylinder connector plate. A hook plate is movably connected to the inner side wall of the connecting rod.

[0006] Through the above technical solution, the fulcrum is constructed by the first and second pins. The linear motion of the electric push cylinder is converted into the planar motion of the connecting rod through the mounting block and the push cylinder connector plate, which ultimately drives the hook plate to rotate around the second pin to achieve opening and closing. The unhooking action is smoother, and the hoisted goods can be quickly separated from the drone. The weight of the goods can be monitored in real time through the weighing sensor.

[0007] The present invention is further configured such that a fixing plate is provided through the front surface of the housing, and a first screw is threadedly connected to the front surface of the fixing plate, and the fixing plate and the housing are fixedly connected by the first screw.

[0008] With the above technical solution, the fixing plate is connected to the housing by the first screw, and the position of the fixing plate can be adjusted according to the installation requirements.

[0009] The present invention is further configured such that the electric push cylinder is located inside the housing, and the two sides of the electric push cylinder are in contact with the inner wall of the fixed plate.

[0010] Through the above technical solution, the fixing plate is used to limit the electric push cylinder, keeping the electric push cylinder upright inside the housing, forming a lateral constraint, reducing swaying during the extension and retraction of the electric push cylinder, and improving the thrust transmission efficiency.

[0011] The present invention is further configured such that a second screw is threadedly connected to the side surface of the push cylinder connector plate, and the push cylinder connector plate and the mounting block are fixedly connected by the second screw.

[0012] With the above technical solution, the push cylinder connector plate and the mounting block are connected by the second screw, which facilitates quick disassembly and replacement.

[0013] The present invention is further configured such that a third pin is movably connected through the side surface of the push cylinder connector plate, and the side surface of the third pin is rotatably connected to the connecting rod.

[0014] The above technical solution enables the connecting rod to rotate around the third pin shaft while simultaneously pulling the connecting rod to generate displacement when the push cylinder joint plate is displaced.

[0015] The present invention is further configured such that a fourth pin is movably connected through the side surface of the connecting rod, the side surface of the fourth pin is rotatably connected to the hook plate, and the side surface of the second pin is rotatably connected to the hook plate.

[0016] The present invention is further configured such that the lower ends of the two hook plates are in contact, and the upper and lower ends of the weighing sensor are provided with mounting threaded rods, and the weighing sensor is threadedly connected to the housing through the mounting threaded rod at the lower end.

[0017] With the above technical solution, the lower ends of the two hook plates contact to form a complete bearing surface, and the load cell is connected to the housing by a threaded rod, making the installation process simple.

[0018] The beneficial effects of this utility model are as follows:

[0019] By monitoring the load in real time with a weighing sensor, overload warnings can be accurately issued. Utilizing the lever principle, the hook plate is rotated via an electric actuator, thereby controlling the hook plate to open and quickly separate the hoisted goods from the drone. This ensures reliable and rapid unhooking even under heavy loads. When the cargo rope becomes entangled in tree branches and the drone cannot escape, the operator can remotely control the hook plate to open and unhook the rope without approaching the danger zone. This approach offers a fast response and high safety. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] like Figures 1-5 As shown, this embodiment of a remotely controlled cargo-throwing hook includes a housing 1 and a load cell 14. The load cell 14 has threaded rods 141 at both its upper and lower ends. The load cell 14 and housing 1 are threaded together via the lower threaded rod 141. The device can be mounted on a drone via the upper threaded rod 141. A fixing plate 2 is provided through the front surface of the housing 1. The fixing plate 2 is connected to the housing 1 via a first screw 3. The position of the fixing plate 2 can be adjusted according to installation requirements. The front surface of the fixing plate 2 is threaded together... A first screw 3 is attached, and the fixing plate 2 is fixedly connected to the housing 1 by the first screw 3. A first pin 4 is movably connected through the front surface of the housing 1, and a second pin 5 is movably connected through the front surface of the housing 1. An electric push cylinder 6 is movably connected to the side surface of the first pin 4. The electric push cylinder 6 is located inside the housing 1, and the two sides of the electric push cylinder 6 are in contact with the inner wall of the fixing plate 2. The fixing plate 2 is used to limit the electric push cylinder 6, so that the electric push cylinder 6 remains upright inside the housing 1, forming a lateral constraint, reducing shaking during the extension and retraction of the electric push cylinder 6, and improving the thrust transmission efficiency.

[0028] Both the weighing sensor 14 and the electric push cylinder 6 are electrically connected to the external drone controller. The electric push cylinder 6 can be started and stopped remotely. The weighing sensor 14 monitors the weight of the suspended cargo in real time and transmits the information to the remote controller. This is known to those skilled in the art. Both the first screw 3 and the second screw 9 are internal hexagonal flat head screws.

[0029] An electric push cylinder 6 has a mounting block 7 fixedly connected to its output end. A push cylinder connector plate 8 is symmetrically and movably connected to the side surface of the mounting block 7. When the electric push cylinder 6 is activated, it can push the mounting block 7 and the push cylinder connector plate 8 upwards. A second screw 9 is threaded onto the side surface of the push cylinder connector plate 8, and the push cylinder connector plate 8 and the mounting block 7 are fixedly connected by the second screw 9. A connecting rod 11 is symmetrically and movably connected to the side surface of the push cylinder connector plate 8. When the push cylinder connector plate 8 moves upwards, it pulls the connecting rod 11 to move via a third pin 10. The side surface of the push cylinder connector plate 8 is traversed by the movable connecting rod 11. A third pin 10 is connected, and the side surface of the third pin 10 is rotatably connected to the connecting rod 11. A hook plate 13 is movably connected to the inner side wall of the connecting rod 11. When the connecting rod 11 is displaced, it pulls the hook plate 13 through the fourth pin 12, causing the hook plate 13 to rotate around the second pin 5, thereby causing the lower end of the hook plate 13 to separate. At this time, the internal rope is unhooked. The side surface of the connecting rod 11 is movably connected to the fourth pin 12, and the side surface of the fourth pin 12 is rotatably connected to the hook plate 13. The side surface of the second pin 5 is rotatably connected to the hook plate 13, and the lower ends of the two hook plates 13 are in contact.

[0030] The first pin 4 and the second pin 5 form a fulcrum. The linear motion of the electric push cylinder 6 is converted into the planar motion of the connecting rod 11 through the mounting block 7 and the push cylinder connector plate 8. Finally, the hook plate 13 is driven to rotate around the second pin 5 to achieve opening and closing. The unhooking action is smoother, and the hoisted goods can be quickly separated from the drone. When the drone is entangled in ropes and branches and cannot get out, it can be freed without personnel having to travel a long distance to the site, which improves operational safety. The weight of the goods can be monitored in real time by the weighing sensor 14. The first pin 4, the second pin 5, the third pin 10 and the fourth pin 12 are all equipped with pins, and the first pin 4, the second pin 5, the third pin 10 and the fourth pin 12 are all equipped with limit sleeves. The limit sleeves are used to limit the position of each component.

[0031] The working principle of this utility model is as follows: the device is installed on the aircraft via the mounting threaded rod 141 at the upper end of the weighing sensor 14. When using this device to lift cargo, the electric push cylinder 6 is remotely activated to push out the mounting block 7, which in turn causes the push cylinder joint plate 8 to move upward and pull the connecting rod 11 to generate displacement. The connecting rod 11 drives the hook plate 13 to move, causing the hook plate 13 to rotate around the second pin 5. During the rotation, the lower end of the hook plate 13 opens, and the cargo rope is placed between the two hook plates 13. Then the electric push cylinder 6 is closed, and the electric push cylinder 6 resets the mounting block 7, the push cylinder joint plate 8, the connecting rod 11, and the hook plate 13. The two hook plates 13 limit the rope. During the flight of the aircraft, the weighing sensor 14 is always under tension to detect the weight and transmit the result to the remote control terminal. When the rope is tangled or needs to be unhooked, the electric push cylinder 6 is remotely activated to rotate the two hook plates 13 to release the limitation on the rope and complete the unhooking action.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
