Description

Technical Field

[0001] This utility model relates to the field of drone application equipment technology, specifically a drone hoisting device with a magnetic suction structure. Background Technology

[0002] Unmanned vehicles, also known as drones, are devices operated using radio remote control equipment and onboard program control devices, or operated autonomously by an onboard computer, either completely or intermittently. These include unmanned aerial vehicles and unmanned vehicles.

[0003] With the development of drone technology, its application in the field of hoisting and transportation is becoming increasingly widespread. Drone hoisting and transportation is suitable for scenarios with complex terrain (such as mountains and ruins) or inconvenient ground transportation. In order to achieve rapid loading and unloading and stable connection of goods using drones, and to improve the efficiency and safety of drone hoisting operations, hoisting equipment is used. Traditional drone hoisting devices mostly adopt a single fixing method, such as pure rope binding, which has the problems of easy shaking of objects and high risk of falling off. Especially under the interference of high-altitude airflow, the stability is insufficient, which restricts the hoisting efficiency and safety. Utility Model Content

[0004] The purpose of this utility model is to provide a drone hoisting device with a magnetic structure to solve the problems mentioned in the background and overcome its technical defects.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a drone hoisting device with a magnetic suction structure, including a main frame, a drone connection component installed at the top of the main frame, a magnetic suction hoisting component fixedly installed on the bottom surface of the main frame, a clamping component fixedly installed on the inner wall of the main frame, the clamping component including a square support box fixedly connected to the inner wall of the main frame, two electric push rods fixedly connected to the inner wall of the square support box, a transmission rod fixedly connected to the output end of each electric push rod, a clamping plate fixedly connected to the outer surface of each transmission rod, and two side hooks fixedly connected to the outer surface of the main frame.

[0006] Preferably, a guide slide is fixedly connected to the bottom surface of the square support box, and two square slide plates are slidably connected inside the guide slide. One end of each square slide plate is fixedly connected to the outer surface of the transmission rod.

[0007] Preferably, the drone connection assembly includes a connector fixedly connected to the upper surface of the main frame, and the outer surface of the connector has multiple connection holes.

[0008] Preferably, the bottom surface of each of the connecting seats is fixedly connected to the top end of the side hook.

[0009] Preferably, the magnetic lifting assembly includes a magnetic chuck fixedly connected to the main frame, and the magnetic chuck is provided with multiple neodymium iron boron permanent magnets inside, and the multiple neodymium iron boron permanent magnets are evenly distributed in a ring.

[0010] Preferably, an electromagnetic coil is mounted on the outer surface of the magnetic chuck.

[0011] Preferably, the inner wall of the main frame is fixedly connected to two flow guide plates, each of which is triangular.

[0012] Preferably, the inner wall of the main frame is fixedly connected to two reinforcing ribs, which are located on both sides of the clamping assembly.

[0013] Compared with the prior art, the beneficial effects of this utility model include: The magnetic suction cup of the magnetic hoisting component uses neodymium iron boron permanent magnets to generate strong magnetic force to attract metal objects. At the same time, the electric push rod of the clamping component drives the clamping plate to clamp the object from both sides, forming a three-dimensional fixing structure of upper and lower magnetic attraction and side clamping. Compared with the traditional single fixing method, it can counteract the shaking caused by high-altitude airflow, solve the problem of easy detachment of single fixing, improve the safety of high-altitude transportation, realize the coordinated fixing of magnetic attraction and clamping, and improve the hoisting stability.

[0014] Furthermore, the electric push rod of the clamping component can extend and adjust the spacing of the clamping plates to accommodate metal objects of different widths. The electromagnetic coil of the magnetic component can adjust the magnetic strength, such as reducing the attraction force for thin and light parts to avoid deformation. This solves the problems of fixed specifications and poor adaptability of traditional devices and improves work efficiency. Attached Figure Description

[0016] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0017] According to one embodiment of the present invention, in conjunction with the appended drawings Figures 1-4 As shown.

[0018] A drone hoisting device with a magnetic suction structure includes a main frame 1, a drone connection component 3 installed at the top of the main frame 1, a magnetic hoisting component 2 fixedly installed on the bottom surface of the main frame 1, and a clamping component 5 fixedly installed on the inner wall of the main frame 1. The clamping component 5 includes a square support box 51 fixedly connected to the inner wall of the main frame 1, two electric push rods 52 fixedly connected to the inner wall of the square support box 51, a transmission rod 53 fixedly connected to the output end of each electric push rod 52, a clamping plate 54 fixedly connected to the outer surface of each transmission rod 53, and two side hooks 4 fixedly connected to the outer surface of the main frame 1. The magnetic suction component provides vertical suction, the clamping component 5 limits the position from the side, and the side hooks 4 can assist in fixation. The three components work together to achieve stable hoisting, solving the stability problem of traditional single fixation and laying the foundation for hoisting in multiple scenarios.

[0019] In this embodiment, a guide slide cylinder 8 is fixedly connected to the bottom surface of the square support box 51. Two square slide plates 9 are slidably connected inside the guide slide cylinder 8. One end of each square slide plate 9 is fixedly connected to the outer surface of the transmission rod 53. The guide slide cylinder 8 and the square slide plates 9 cooperate to limit the movement trajectory of the transmission rod 53, ensuring that the clamping plate 54 is horizontally stable when it is translated, and avoiding one-sided clamping or one-sided loosening caused by the tilt of the clamping plate 54. The UAV connection component 3 includes a connecting seat 301 fixedly connected to the upper surface of the main frame 1. The outer surface of the connecting seat 301 is opened. With multiple connection holes 302, the connector 301 of the UAV connector assembly 3 can be adapted to the mounting interfaces of different UAV models, such as the mounting points of multi-rotor UAVs, through multiple connection holes 302. No custom connectors are required, which improves the compatibility of the device with various UAVs and lowers the usage threshold. The bottom surface of each connector 301 is fixedly connected to the top of the side hook 4. The connection between the connector 301 and the side hook 4 allows the force of the side hook 4 to be directly transmitted to the UAV connection point, avoiding deformation of the main frame 1 due to excessive force on the side hook 4.

[0020] In this embodiment, the magnetic lifting assembly 2 includes a magnetic chuck 201 fixedly connected to the main frame 1. The magnetic chuck 201 contains multiple neodymium iron boron permanent magnets 202 arranged in a ring-shaped, uniform distribution. An electromagnetic coil 203 is mounted on the outer surface of the magnetic chuck 201. Each neodymium iron boron permanent magnet 202 has a magnetic force ≥50kg. The ring-shaped, uniform distribution of the neodymium iron boron permanent magnets ensures uniform magnetic force across the magnetic chuck 201, preventing object tilting due to uneven magnetic force. The electromagnetic coil 203 is controlled by a drone controller to switch the current on and off, achieving magnetic... The suction power can be quickly switched and adjusted according to the weight of the object. The suction power is reduced for lightweight parts to avoid the object being too tightly attached and difficult to separate. The inner wall of the main frame 1 is fixedly connected to two guide plates 6. Each guide plate 6 is triangular. The triangular guide plates 6 can guide the airflow during the flight of the drone, such as reducing the impact of the airflow below on the object being lifted and reducing the shaking of the object caused by airflow disturbance. The inner wall of the main frame 1 is fixedly connected to two reinforcing ribs 7. The two reinforcing ribs 7 are located on both sides of the clamping component 5. The reinforcing ribs 7 are located on both sides of the clamping component 5 to enhance the connection strength between the main frame 1 and the clamping component 5.

[0021] Working principle: When hoisting materials, the connecting seat 301 of the drone connecting component 3 can be adapted to different models of drones through multiple connecting holes 302. After installation, the material can be attracted to the top center part by the magnetic suction cup 201. Then, the two electric push rods 52 can be started to drive the clamping plate 54 to clamp the two sides of the material. The side hook 4 can be connected to the spare rope. Then, when the drone is hoisting and flying, the material will not shake or fall significantly.

[0022] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
