[0017] The present invention provides a UAV anti-sway mechanical claw, which has the following beneficial effects:

[0018] 1. The anti-sway mechanical claw of the UAV is designed with a composite mechanism. The motor controls the rope inside the electric hoist to retract and retract, which is convenient for adjusting the length of the rope and expanding the scope of application. The rope is collected by the electric hoist to drive the grabbing mechanism to rise, so that the connecting block and the processing mechanism are docked, so as to achieve the function of fixing the components. By shortening the rope, the jitter during flight is reduced, and the stability of the equipment is increased, thereby achieving the anti-sway effect, improving the stability of material transportation, and improving the transportation efficiency. The grabbing mechanism adopts an electric contraction grabbing method to clamp the material, so as to achieve the function of fixing the material. The friction force on the rope is increased by the friction mechanism, so as to achieve the effect of uniform lifting and lowering, further improving the stability of the equipment, while avoiding mechanical failures and preventing components from derailing.

[0019] 2. The anti-sway mechanical claw of the drone is designed with a grabbing mechanism. By rotating the shaft inside the grabbing frame, it drives the arm claw to retract toward the middle, so as to grab objects and facilitate the subsequent transportation of objects.

[0020] 3. The anti-sway mechanical claw of the drone is designed with a fixed mechanism. When the arm claw grabs the material and flies in the air, it is easily affected by the external wind force and speed inertia, which may cause the material to slide. The sliding block fits the surface of the material, and as the material shakes, the sliding block slides on the connecting rod, thereby automatically adjusting the force angle and improving the fixing effect of the material. At the same time, the spring bar plays a shock-absorbing and buffering role, reducing the amplitude of components, keeping the equipment stable, and avoiding affecting the flight effect. One side of the sliding block adopts a diamond structure to increase the contact area with the material, enhance the friction effect, and have a certain anti-slip effect.

[0021] 4. The anti-swing mechanical claw of the drone is designed with a friction mechanism. The rope penetrates the circular shell and rotates and rubs with the gear block, so as to slow down the lifting speed of the component by friction, thereby achieving the effect of uniform lifting and lowering, preventing sudden loss of control and causing equipment failure, reducing component wear by uniform sliding, and extending the service life of the equipment. After controlling the lifting speed of the rope by friction of the gear block, the first electric push rod controls the curved plate to clamp the rope, thereby achieving a braking effect on the component, preventing the component from breaking and falling, and providing a certain protection for the equipment. The curved plate adopts a reverse bow structure to increase the load-bearing capacity of the component and improve the stability of the structure. The friction strip is made of rubber material, which increases the friction resistance and has a certain wear-resistant effect, reducing the wear of the components.

[0022] 5. The anti-sway mechanical claw of the drone is designed with a processing mechanism. When the rope drives the connecting block to contract, it enters the inside of the square plate. While squeezing the square plate, the spring rod supports the square plate to achieve the function of clamping the component. The swing space is reduced by contracting the rope. At the same time, the stability of the structure is increased by clamping the component, and the anti-sway effect of the component is improved to facilitate smooth flight in the later stage. After the connecting block enters the clamping plate, it squeezes the clamping plate while supporting the clamping plate through the elastic rod to achieve the clamping effect of the component. Through the support of the elastic structure on both sides, the effect of shock absorption and buffering is achieved, the amplitude during flight is reduced, the stability of flight is improved, and the operating efficiency of the equipment is improved. By opening strip incisions and grooving to increase the contact area, the friction force is increased, and a certain anti-slip effect is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

The motor 14 controls the rope 15 inside the electric hoist 13 to retract and retract, which is convenient for adjusting the length of the rope and expanding the scope of application. The rope 15 is collected by the electric hoist 13 to drive the grabbing mechanism 17 to rise, so that the connecting block 16 is docked with the processing mechanism 2, so as to achieve the function of fixing the components. By shortening the rope, the jitter during flight is reduced, and the stability of the equipment is increased, thereby achieving the anti-sway effect, improving the stability of material transportation, and improving the transportation efficiency. The grabbing mechanism 17 adopts an electric contraction grabbing method to clamp the material, so as to achieve the function of fixing the material. The friction force on the rope 15 is increased by the friction mechanism 18, so as to achieve the effect of uniform lifting and lowering, further improving the stability of the equipment, while avoiding mechanical failures and preventing components from derailing.

[0038] The second embodiment is based on the first embodiment. Figures 4 to 6 As shown, the grabbing mechanism 17 includes a grabbing frame 171, the top of the grabbing frame 171 is threadedly connected to the bottom of the connecting block 16, the inner side of the grabbing frame 171 is rotatably connected to a rotating shaft 172, the outer side of the grabbing frame 171 is fixedly connected to a connecting frame 173, the outer side of the connecting frame 173 away from the grabbing frame 171 is fixedly connected to an arm claw 174, the outer side of the arm claw 174 is fixedly connected to the outer side of the rotating shaft 172, and the outer side of the arm claw 174 away from the rotating shaft 172 is fixedly connected to a fixing mechanism 175. The rotating shaft 172 rotates toward the inside of the grabbing frame 171, driving the arm claw 174 to shrink toward the middle, so as to achieve the effect of grabbing objects, which is convenient for the later transportation of objects. At the same time, the fixing mechanism 175 increases the contact area with the material, increases the friction force, further improves the grabbing effect, and prevents the material from slipping and affecting the normal operation of the equipment.

The rope 15 penetrates the circular shell 182 and performs rotational friction with the gear block 184, so as to slow down the lifting speed of the component by friction, thereby achieving the effect of uniform lifting, preventing sudden loss of control and causing equipment failure, reducing component wear by uniform sliding, and extending the service life of the equipment.

[0041] A support plate 185 is fixedly connected to the side of the friction bottom plate 181 near the circular shell 182, a first electric push rod 186 is fixedly connected to the outside of the support plate 185, an arc frame 187 is fixedly connected to the side of the first electric push rod 186 near the circular shell 182, a curved plate 188 is fixedly connected to the side of the curved frame 187 away from the first electric push rod 186, and a friction strip 189 is fixedly connected to the side of the curved plate 188.

The friction strip 189 is made of rubber material, which increases the friction resistance and has a certain wear-resistant effect to reduce the wear of the components.

[0042] The third embodiment is based on the first and second embodiments. Figures 7 and 8As shown, the processing mechanism 2 includes a processing top plate 21, the top of the processing top plate 21 is fixedly connected to the bottom of the composite bottom plate 12, a receiving plate 22 is fixedly connected to the side of the processing top plate 21 away from the composite bottom plate 12, a spring rod 23 is slidably connected to the outer side of the receiving plate 22, and a square plate 24 is fixedly connected to the outer side of the spring rod 23. When the rope 15 drives the connecting block 16 to contract, it enters the inside of the square plate 24, and while squeezing the square plate 24, the spring rod 23 supports the square plate 24, thereby achieving the function of the clamping component, reducing the swing space by contracting the rope 15, and at the same time, by means of the clamping component, increasing the stability of the structure, improving the anti-swaying effect of the component, and facilitating stable flight in the later stage.

[0043] The side of the square plate 24 away from the spring rod 23 is fixedly connected with an elastic rod 25, and the side of the elastic rod 25 away from the square plate 24 is fixedly connected with a clamping plate 26. The side of the clamping plate 26 away from the elastic rod 25 is provided with a strip cutout 27, and the side of the clamping plate 26 close to the strip cutout 27 is provided with a circular groove 28, and the inner wall of the circular groove 28 is plugged and connected with a clamping mechanism 29.

[0046] When in use, the electric hoist 13 inside the composite mechanism 1 controls the rope 15 to be raised and lowered, which is convenient for controlling the movement of the grabbing mechanism 17 and improving the convenience of use. After the material is clamped and fixed by the grabbing mechanism 17, the material is driven to move by the drone. During the flight of the drone, due to the change in speed, the influence of external airflow and the weight of the material, the flight of the drone is easily unstable, which may cause the crash of the drone. The motor 14 is started to make the electric hoist 13 drive the rope 15 to dock the grabbing mechanism 17 with the processing mechanism 2.

On the one hand, the stability of grabbing and taking materials is maintained, and on the other hand, the wear of components is reduced and the service life of the equipment is extended. At the same time, the friction mechanism 18 can have a braking effect on the rope 15 to avoid the rope 15 from breaking and derailing, avoid material loss, and improve the safety of equipment operation.
