Description

Technical Field

[0001] This utility model relates to the field of highway engineering inspection technology, and in particular to a multi-angle shooting gimbal device for a highway crack detection drone. Background Technology

[0002] In the field of highway maintenance, timely and accurate detection of road surface cracks is crucial for ensuring road safety. With the development of drone technology, highway crack detection drones have gradually become the mainstream detection equipment due to their high efficiency and flexibility. Among them, the multi-angle shooting gimbal device, as the core component of the drone, can carry camera equipment to acquire road surface images from different perspectives, providing data support for crack identification and analysis. Its performance directly affects the detection efficiency and accuracy.

[0003] Traditional highway crack detection drones typically employ single-axis or dual-axis mechanical structures for their gimbals, achieving image capture through fixed-angle or limited-range rotation. For example, some gimbals only have a vertical downward shooting capability, relying on the drone's own attitude adjustment to acquire images from different angles; while other dual-axis gimbals can achieve pitch and horizontal rotation, their angle adjustment range is limited and requires complex flight control algorithms for coordinated control. These structures mainly rely on rigid linkages and gear transmissions, using motors to drive the overall rotation of the gimbal or the lens tilt to complete the limited-angle shooting task.

[0004] However, the aforementioned traditional pan-tilt devices have significant drawbacks in practical applications. Due to their limited viewing angle and adjustment range, they cannot comprehensively cover the detection needs of complex road surface cracks. For example, special types of defects such as transverse cracks and network cracks are easily lost due to shadows, obstructions, or parallel shooting directions when shooting from a single angle, leading to missed detections. This makes it difficult to provide complete and accurate detection data for highway maintenance, seriously affecting the scientific and timely nature of maintenance decisions. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-angle shooting gimbal device for highway crack detection drones, which aims to improve the problem that traditional shooting angles are limited and cracks are easily missed.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-angle shooting gimbal device for a highway crack detection drone, comprising a drone body, a multi-angle adjustment component disposed below the drone body, and an installation component disposed below the drone body; The multi-angle adjustment component includes a gimbal cylinder, which is located below the drone body. An electric push rod is fixedly connected to the lower inner wall of the gimbal cylinder, and a push rod is fixedly connected to the output end of the electric push rod.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figures 1-3 The present invention provides an embodiment of a multi-angle shooting gimbal device for a highway crack detection drone, comprising a drone body 1, a multi-angle adjustment component disposed below the drone body 1, and an installation component disposed below the drone body 1. The multi-angle adjustment assembly includes a gimbal cylinder 5, which is located below the drone body 1. An electric push rod 16 is fixedly connected to the lower inner wall of the gimbal cylinder 5. A push rod 8 is fixedly connected to the output end of the electric push rod 16. A sliding table 9 is slidably connected to the outer wall of the push rod 8. By being fixedly connected to the push rod 8, the table slides on the surface of the gimbal cylinder 5. The arc-shaped groove 22 on its inner wall cooperates with the sliding ball 14, pulling the rotating rod 13 to rotate, thereby changing the pitch angle of the camera 2. A motor 15 is fixedly connected to the upper inner wall of the gimbal cylinder 5. The motor 15 outputs… A rotating column 11 is fixedly connected to one end of the sliding table 9.

A sliding ball 14 is fixedly connected to one end of the rotating rod 13 and cooperates with the arc-shaped groove 22 on the inner wall of the sliding table 9. When the sliding table 9 slides, it slides along the arc-shaped groove 22, thereby pulling the rotating rod 13 to rotate. The inner wall of the sliding table 9 has an arc-shaped groove 22.

[0020] Specifically, when the shooting angle of camera 2 needs to be adjusted, the electric push rod 16 is activated to drive the push rod 8, causing the sliding table 9 to slide on the surface of the gimbal cylinder 5. By utilizing the cooperation of the arc-shaped sliding groove 22 and the sliding ball 14, the rotating rod 13 is pulled to rotate around the rotating shaft 12, thereby changing the pitch angle of camera 2. At the same time, the motor 15 drives the rotating column 11 to drive the rotating shaft 12, allowing camera 2 to rotate in the horizontal direction. Through bidirectional adjustment of pitch and horizontal, the road surface can be covered in all directions, avoiding the omission of cracks due to limited viewing angle, achieving efficient multi-angle shooting, and accurately acquiring crack images.

[0021] Reference Figures 1-4The installation components include a mounting box 3, whose upper surface is fixedly connected to the lower surface of the drone body 1. Two buttons 4 are slidably connected to both sides of the inner wall of the mounting box 3. One button 4 has a sliding rod 18 fixedly connected to its outer wall, and the other button 4 has a sliding rod 20 fixedly connected to its outer wall. A spring 21 is fixedly connected to the outer wall of the sliding rod 18. L-shaped fixing rods 17 are fixedly connected to the lower surfaces of both the sliding rod 18 and the sliding rod 20. Driven by the sliding rods 18 and 20, these rods can extend and retract, inserting into or disengaging from the L-shaped fixing grooves 7 of the connecting post 6, thus enabling the installation and disassembly of the gimbal cylinder 5 from the drone body 1. A sliding groove 19 is provided on the lower side of the inner wall of the mounting box 3. A connecting post 6 is fixedly connected to the upper surface of the gimbal cylinder 5, cooperating with the mounting box 3. The L-shaped fixing grooves 7 on its inner wall are used to hold the L-shaped fixing rods. 17. To achieve a stable connection between the gimbal cylinder 5 and the UAV body 1, an L-shaped fixing groove 7 is provided on the inner wall of the connecting column 6. The outer wall of the L-shaped fixing rod 17 is slidably connected to the inside of the L-shaped fixing groove 7. The L-shaped fixing rod 17 is used to fix the connecting column 6. One end of the spring 21 is fixedly connected to the outer wall of the sliding rod 20. The spring 21 is used to push the sliding rod 18 and the sliding rod 20 to move. The outer wall of the L-shaped fixing rod 17 is slidably connected to the inside of the sliding groove 19. The sliding groove 19 is used to guide the sliding of the L-shaped fixing rod 17. The outer wall of the sliding ball 14 is slidably connected to the inside of the arc-shaped sliding groove 22. The arc-shaped sliding groove 22 is used to guide the sliding of the sliding ball 14. The inner wall of the sliding platform 9 is slidably connected to the outer wall of the gimbal cylinder 5. The sliding platform 9 is used to pull the rotating rod 13 to rotate. The outer wall of the push rod 8 is slidably connected to the inner wall of the gimbal cylinder 5. The push rod 8 is used to drive the sliding platform 9 to slide.

[0022] Specifically, when installing the gimbal tube 5, align the connecting post 6 with the mounting box 3, press button 4 to move the L-shaped fixing rod 17 inward, compress the spring 21, and after insertion, release button 4. The spring 21 will return to its original position and push the L-shaped fixing rod 17 into the L-shaped fixing groove 7 to complete the fixing. To disassemble, press button 4 again, and the L-shaped fixing rod 17 will detach and can be removed. This allows for quick installation and disassembly of the gimbal tube 5 and the UAV body 1, facilitating equipment maintenance, replacement, and the replacement of other components according to different testing needs, thereby improving work efficiency.

[0023] Working principle: When a multi-angle shooting gimbal device for a highway crack detection drone is needed, and the shooting angle of camera 2 needs to be adjusted, the electric push rod 16 is activated. Its output end drives the push rod 8 to move. The sliding table 9 on the push rod 8 slides on the surface of the gimbal cylinder 5. The arc-shaped sliding groove 22 inside the sliding table 9 cooperates with the sliding ball 14 at one end of the rotating rod 13. When the sliding table 9 slides, it pulls the rotating rod 13 to rotate around the rotating shaft 12, thereby changing the pitch angle of camera 2. At the same time, the rotating column 11 at the output end of the motor 15 drives the rotating shaft 12 to rotate, so that the connecting rod 10 and camera 2 rotate in the horizontal direction to achieve multi-angle shooting. During installation, align the connecting post 6 on the gimbal tube 5 with the mounting box 3, and press both buttons 4 simultaneously. This causes the sliding rod 18 and sliding rod 20 to move the L-shaped fixing rod 17 inward, compressing the spring 21. Once the connecting post 6 is inserted into the mounting box 3, release the buttons 4. The spring 21 will then return to its original position, pushing the L-shaped fixing rod 17 outward. The L-shaped fixing rod 17 will then engage with the L-shaped fixing groove 7 inside the connecting post 6, thus securing the gimbal tube 5 to the drone body 1. To disassemble, press the buttons 4 again. The L-shaped fixing rod 17 will disengage from the L-shaped fixing groove 7, allowing the gimbal tube 5 to be removed.
