[0040] In order to solve the reliability problem of the heavy object mounting device, the present disclosure provides a mounting device for aerial transportation equipment and an aerial transportation system. Figures 1 to 4 , the specific structure and working principle of the mounting device and the aerial transportation system disclosed in the present invention are explained in detail in combination with the embodiments.
[0041] In one embodiment, the mounting device of the aerial transportation equipment of the present invention includes a lifting rope 1, a connecting member 4, a fixed hook 5, a movable hook 6, and a limiter 7, wherein the lifting rope 1 is arranged on the aerial transportation equipment 3 in a retractable manner through a rope retracting mechanism 2; the connecting member 4 is arranged at the free end of the lifting rope 1; one end of the fixed hook 5 is fixedly connected to the connecting member 4; one end of the movable hook 6 is rotatably arranged on the connecting member 4; the limiter 7 is arranged on the aerial transportation equipment 3, and is constructed to limit the rotation of the movable hook 6 relative to the fixed hook 5 after the other ends of the fixed hook 5 and the movable hook 6 hook the target object, and the limit is eliminated after the lifting rope 1 drives the connecting member 4 to descend a preset distance, so that the movable hook 6 rotates relative to the fixed hook 5 until it is removed from the target object.
[0042] Specifically, the rope retracting mechanism 2 is arranged on the aerial transport equipment 3, and the connecting member 4 is released or retracted from the aerial transport equipment 3 by the lifting rope 1. One end of the fixed hook 5 is fixedly connected to the connecting member 4; one end of the movable hook 6 is rotatably connected to the connecting member 4, and the other end of the fixed hook 5 abuts against the other end of the movable hook 6 to form a closed loop, which hooks the target object and prevents the target object from being loosened from the other end of the fixed hook 5 and the other end of the movable hook 6. The movable hook 6 can rotate relative to the fixed hook 5, and the other end of the fixed hook 5 is separated from the other end of the movable hook 6, so that the target object can be loosened. The target object specifically includes rescue supplies, goods, etc.
[0043] In detail, a limiter 7 is provided at the bottom of the aerial transport device 3, and the limiter 7 is a straight rod. When the connecting member 4 is retracted, the limiter 7 limits the rotation of the movable hook 6 relative to the fixed hook 5, so that the target object is mounted on the aerial transport device 3. When the rope retracting and releasing mechanism 2 releases the connecting member 4 through the lifting rope 1 to descend a preset distance, the limiter 7 is disengaged, so that the movable hook 6 is no longer limited, and under the action of the gravity of the target object, the movable hook 6 can rotate relative to the fixed hook 5 to loosen the target object.
[0044] Working process of the mounting device of air transport equipment:
[0045] When a heavy object is mounted, the heavy object is mounted on the movable hook 6, and the movable hook 6 is abutted against one end of the fixed hook 5 by an external force to form a closed loop. The rope retracting mechanism 2 retracts the lifting rope 1, and the limiter 7 limits the rotation of the movable hook 6.
[0046] When releasing the heavy object, the rope retracting mechanism 2 releases the lifting rope 1. When the connecting member 4 drops a preset distance, the limiting member 7 eliminates the limiting effect on the movable hook 6. Under the action of the gravity of the target object, the movable hook 6 rotates relative to the fixed hook 5, and the target object is loosened.
[0047] With the mounting device disclosed in the present invention, when mounting the target object, the limiter 7 can limit the rotation of the movable hook 6 to prevent the target object from falling from a high altitude and causing damage to the target object or injuring people, thereby ensuring the safety of the target object transported by the aerial transportation equipment 3. When arriving at the designated location, the rope retracting mechanism 2 releases the lifting rope 1, the connecting member 4 drops a preset distance, and the limiter 7 removes the limit, so that the movable hook 6 rotates relative to the fixed hook 5, the target object is loosened, and the timeliness of the aerial transportation is ensured.
[0048] In one embodiment, the mounting device also includes a limit gear 8, which is rotatably arranged on the connecting member 4 and fixedly connected to one end of the movable hook 6; and the limit gear 8 is constructed to drive the movable hook 6 to rotate relative to the fixed hook 5 under external force until the limit member 7 is inserted into the tooth groove, so as to limit the rotation of the movable hook 6 relative to the fixed hook 5, and rotate in the opposite direction after the limit member 7 is removed from the tooth groove.
[0049] Specifically, the limit gear 8 is a component with a gear, which can rotate relative to the connector 4. One end of the movable hook 6 on the end face of the limit gear 8 is fixedly connected. When the limit member 7 is inserted into the tooth groove, the limit gear 8 is restricted from rotating, thereby locking the position of the movable hook 6. When the target object needs to be mounted, the movable hook 6 cooperates with the fixed hook 5 to form a complete annular structure. Through manual operation or motor braking, the limit gear 8 drives the movable hook 6 to rotate relative to the fixed hook 5, and the movable hook 6 cooperates with the fixed hook 5 to form a complete annular structure, and the limit member 7 is inserted into the tooth groove. Once the limit member 7 is inserted into the tooth groove, the movable hook 6 is locked to prevent it from rotating relative to the fixed hook 5, thereby ensuring that the goods will not fall off during transportation. When the target object needs to be released, the connector 4 drops a preset distance until the limit member 7 withdraws from the tooth groove. The limit gear 8 can rotate, and the movable hook 6 is also unlocked. Under the gravity of the target object, the movable hook 6 rotates, so that the movable hook 6 is separated from the fixed hook 5, and the target object is loosened. The safety and timeliness of air transportation are guaranteed. At the same time, the mechanical locking structure can ensure that there is no risk of the target object getting loose when there is no power.
[0050] In one embodiment, an elastic element 9 is arranged between the connecting member 4 and the movable hook 6, and the elastic element 9 is configured to be in an energy storage state when the limiting member 7 limits the rotation of the movable hook 6 relative to the fixed hook 5, and to release elastic potential energy to assist in pushing the movable hook 6 to rotate relative to the fixed hook 5 after the limiting member 7 eliminates the limitation.
[0051] Specifically, an elastic element 9 is provided between the connector 4 and the movable hook 6. With the help of external force, when the limiter 7 limits the rotation of the movable hook 6 relative to the fixed hook 5, the elastic element 9 is in an energy storage state, and when the limiter 7 eliminates the limit, the elastic element 9 can release the elastic potential energy. Since the mass of the movable hook 6 is much smaller than the mass of the connector 4, the elastic element 9 pushes the movable hook 6, and the movable hook 6 can rotate relative to the fixed hook 5. In order to ensure that the movable hook 6 and the fixed hook 5 form a tight closed loop, a certain pre-tightening force is provided to prevent the movable hook 6 from being easily separated from the fixed hook 5. When the weight of the target object is high, the movable hook 6 can be separated from the fixed hook 5 by its own weight, and when the weight of the target object is low, the movable hook 6 cannot be separated from the fixed hook 5 by its own weight alone, so the elastic potential energy of the elastic element 9 can be used to separate the movable hook 6 from the fixed hook 5.
[0052] In one embodiment, the elastic element 9 is a compression spring.
[0053] Specifically, the compression spring is a standard part that is easy to adapt and replace. Using the compression spring as the elastic element 9 can effectively improve the performance of the mounting device and enhance its safety and reliability.
[0054] In one embodiment, the fixed hook 5 is an arc-shaped hook; the mounting device also includes a connecting hook 10, one end of which is fixedly connected to the connecting member 4, and the other end is rotatably provided with a limit gear 8, one end of the movable hook 6 is fixedly connected to the limit gear 8, and the other end is constructed to be inserted into the target object, and the connecting hook 10 and the movable hook 6 are combined into an arc-shaped hook.
[0055] Specifically, the mounting device also includes a connecting hook 10, one end of which is fixedly connected to the connecting member 4, and the other end is rotatably provided with a limiting gear 8. One end of the movable hook 6 is fixedly connected to the end face of the limiting gear 8, and the movable hook 6 can rotate with the rotation of the limiting gear 8. The movable hook 6 and the connecting hook 10 are combined into an arc-shaped hook, and the fixed hook 5 is also an arc-shaped hook, which together form a circular ring shape, so that the target object is hooked in the circular ring and cannot be loosened.
[0056] In one embodiment, a first mounting groove 11 is provided at one end of the connecting hook 10 , a second mounting groove 12 is provided at one end of the movable hook 6 , one end of the elastic element 9 is fixedly connected to the first mounting groove 11 , and the other end abuts against the second mounting groove 12 .
[0057] Specifically, a first mounting groove 11 is provided at one end of the connecting hook 10, one end of the elastic element 9 is fixedly connected to the first mounting groove 11, a second mounting groove 12 is provided at one end of the movable hook 6, and the other end of the elastic element 9 abuts against the second mounting groove 12. Since the other end of the connecting hook 10 is fixedly connected to the connecting member 4, and the mass of the movable hook 6 is much smaller than that of the connecting member 4, when the elastic element 9 releases its elastic potential energy, it pushes the movable hook 6 to rotate through the second mounting groove 12.
[0058] In one embodiment, a connecting pin 13 is fixedly provided at the end of the movable hook 6 , and the end of the connecting pin 13 is inserted into the outer end of the limiting gear 8 and fixedly connected to the limiting gear 8 .
[0059] Specifically, one end of the movable hook 6 is inserted into the outer end of the limiting gear 8 by setting a connecting pin 13 to achieve a fixed connection with the limiting gear 8. Such a setting ensures that the rotation of the movable hook 6 is synchronized with the limiting gear 8, and the rotation of the movable hook 6 is limited by limiting the rotation of the limiting gear 8.
[0060] In one embodiment, the mounting device further includes a connecting shaft 14 , the connecting shaft 14 is fixedly connected to the connecting member 4 , and the limiting gear 8 is rotatably disposed on the connecting shaft 14 via a rotating bearing 15 .
[0061] Specifically, the connecting shaft 14 is fixedly connected to the connecting member 4, and the rotation bearing 15 of the limit gear 8 is rotatably arranged on the connecting shaft 14. Such an arrangement can reduce friction and wear, improve efficiency and extend the service life of the machine.
[0062] In one embodiment, the rope retracting and releasing mechanism 2 comprises a rope drum, and a driving unit, wherein the lifting rope 1 is wound around the rope drum; the driving unit is configured to drive the rope drum to rotate to control the retracting and releasing of the lifting rope 1.
[0063] Specifically, the rope drum is a cylindrical structure for winding and storing the lifting rope 1. Different sizes and materials can be selected according to different application scenarios. The lifting rope 1 is usually made of steel wire, fiber or other high-strength materials for carrying loads. One end of the lifting rope 1 is fixed on the rope drum, and the other end is connected to the connecting member 4. The driving unit is responsible for providing power to rotate the rope drum, and its output shaft is fixedly connected to the rope drum. The driving unit can be set as a driving element such as an electric motor, a hydraulic motor or a manual crank. Preferably, a reduction motor can be used. The specific working process of the rope retracting mechanism 2 is that when the driving unit is started, the driving unit transmits power to the rope drum through a gear box or other transmission components, so that the rope drum starts to rotate. When the rope drum rotates in one direction, the lifting rope 1 will be rolled up, thereby lifting the connecting member 4. When the rope drum rotates in the opposite direction, the lifting rope 1 will be released and the connecting member 4 will drop. The rope retracting mechanism 2 set in this way is very practical and efficient.
[0064] In one embodiment, the air transportation system of the present disclosure includes an air transportation device 3 and the mounting device described in any one of the above embodiments.
[0065] Specifically, the aerial transport equipment 3 is a small or medium-sized UAV for transporting materials. The mounting device is arranged at the bottom of the aerial transport equipment 3, which helps to maintain the stability and balance of the aerial transport equipment 3, making it easier to control, and also makes cargo loading and unloading simple and quick. You only need to unlock the hook to put down the cargo, or lock the hook to load the cargo.
[0066] In addition, in order to facilitate better understanding, the transportation process of the present disclosure is described in detail below in combination with the application scenario of an actual air transportation system.
[0067] 1. The aerial transport equipment 3 is parked on the ground, and the target object is passed through the free end of the movable hook 6 so that it is mounted on the movable hook 6;
[0068] 2. Use external force to make one end of the movable hook 6 abut against one end of the fixed hook 5 to form a closed loop. At this time, the elastic element 9 is in an energy storage state;
[0069] 3. The rope retracting mechanism 2 retracts the lifting rope 1 until the limiting member 7 is inserted into the limiting gear 8, thereby limiting the rotation of the limiting gear 8;
[0070] 4. Start the air transport device 3 and arrive at the designated location;
[0071] 5. The rope retracting and releasing mechanism 2 releases the lifting rope 1 until the limiting member 7 is disengaged from the limiting gear 8, and the limiting gear 8 can rotate;
[0072] 6. The elastic element 9 releases its elastic potential energy, and under the combined effect of the gravity of the target object, the movable hook 6 rotates relative to the fixed hook 5;
[0073] 7. The target object is released from the aerial transport device 3.
