Description

Technical Field

[0001] This utility model relates to the field of road surface crack detection technology, specifically a road surface crack detection device operated by unmanned aerial vehicles (UAVs). Background Technology

[0002] Road surface crack detection refers to the process of detecting, measuring, and evaluating cracks on highway pavements through a series of technologies and methods. In order to assist in the stable detection of road surface cracks, a road surface crack detection device operated by drones is needed.

[0003] Traditional drone-based road crack detection equipment relies on the drone to move the equipment. To assist with positioning, threaded rods are used to adjust the equipment's position from the bottom of the drone. However, traditional methods struggle to adjust the angle of the crack detection equipment, hindering its ability to stably detect cracks of different shapes and thus affecting its stable operation. Furthermore, traditional methods use screws to connect the equipment to the drone, making disassembly time-consuming and labor-intensive, further compromising the equipment's stability. Utility Model Content

[0006] As a preferred technical solution of this utility model, the docking frame has a sliding groove 1 inside, the docking plate has a sliding groove 2 on its side, the docking frame has a limiting groove inside, and the inner wall of the limiting groove is engaged with a limiting plate.

[0007] As a preferred technical solution of this utility model, the shape and size of the outer edge of the limiting plate are adapted to the shape and size of the inner wall of the first slide groove and the inner wall of the second slide groove. An adjusting rod is fixedly mounted on the side of the limiting plate, and an auxiliary plate is rotatably sleeved on the outer edge of the adjusting rod.

[0008] As a preferred embodiment of this utility model, an L-shaped plate is fixedly mounted on the side of the rotating frame, an auxiliary cylinder is fixedly mounted on the L-shaped plate, an auxiliary protrusion is slidably sleeved on the inner wall of the auxiliary cylinder, and an auxiliary groove is provided on the side of the toothed plate.

[0009] As a preferred embodiment of this utility model, the auxiliary cylinder is fixedly connected to a spring, and the end of the spring away from the auxiliary cylinder is fixedly connected to the side of the auxiliary protrusion. The shape and size of the outer edge of the auxiliary protrusion are adapted to the shape and size of the inner wall of the auxiliary groove.

[0010] As a preferred embodiment of this utility model, the number of adjusting rods is three, and the outer edges of the three adjusting rods are rotatably sleeved with the inner wall of the auxiliary plate, and the connection structure of the sides of the three adjusting rods is completely identical.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. The road surface crack detection equipment operated by this UAV uses an electric telescopic rod and a toothed plate in cooperation. The electric telescopic rod drives the toothed plate to move, which in turn drives the gear to rotate. The gear then drives the camera to adjust its angle, and a servo motor drives the camera to adjust its angle. This allows the auxiliary device to be adapted to the angle of the road surface crack. A spring pushes the auxiliary convex rod to move in the inner wall of the auxiliary cylinder. The convex surface of the auxiliary convex rod fits with the concave surface of the auxiliary groove, thereby limiting the toothed plate and limiting the angle of the camera.

[0013] 2. The road surface crack detection equipment operated by this UAV uses a limiting plate and an adjusting rod in combination. The adjusting rod drives the limiting plate to rotate, thereby assisting the outer edge of the limiting plate to rotate in the inner wall of the limiting groove. Then, the adjusting rod moves along the inner wall of the second slide and the inner wall of the first slide, thereby using the adjusting rod to drive the auxiliary plate and the limiting plate to move, and then move the docking plate away from the inner wall of the docking frame, thereby assisting the device to be easily disassembled.

[0026] In a preferred embodiment, the docking frame 2 has a sliding groove 12 inside, the docking plate 3 has a sliding groove 13 on its side, and the docking frame 2 has a limiting groove 14 inside. The inner wall of the limiting groove 14 is engaged with a limiting plate 15. Through the cooperation of the sliding groove 12, the sliding groove 13 and the limiting groove 14, the side of the docking plate 3 is slidably placed in the inner wall of the docking frame 2. Then, the outer edge of the limiting plate 15 passes through the inner wall of the sliding groove 12 and the inner wall of the sliding groove 13 to the inner wall of the limiting groove 14.

[0027] In a preferred embodiment, the shape and size of the outer edge of the limiting plate 15 are adapted to the shape and size of the inner wall of the first slide 12 and the inner wall of the second slide 13. An adjusting rod 16 is fixedly mounted on the side of the limiting plate 15. An auxiliary plate 11 is rotatably sleeved on the outer edge of the adjusting rod 16. Through the cooperation of the adjusting rod 16 and the auxiliary plate 11, the adjusting rod 16 drives the limiting plate 15 to move, thereby assisting in the convenient position adjustment of the limiting plate 15. With the addition of the auxiliary plate 11, it is convenient to limit the three adjusting rods 16 using a single auxiliary plate 11.

[0028] In a preferred embodiment, an L-shaped plate 17 is fixedly mounted on the side of the rotating frame 6, and an auxiliary cylinder 18 is fixedly mounted on the L-shaped plate 17. An auxiliary protruding rod 20 is slidably sleeved on the inner wall of the auxiliary cylinder 18. An auxiliary groove 10 is provided on the side of the toothed plate 5. By adding the L-shaped plate 17, the auxiliary cylinder 18 can be conveniently mounted using the L-shaped plate 17. When the auxiliary protruding rod 20 slides on the inner wall of the auxiliary cylinder 18, the convex surface of the auxiliary protruding rod 20 fits against the concave surface of the auxiliary groove 10, thereby assisting the toothed plate 5 in limiting its position.

[0029] In a preferred embodiment, an auxiliary cylinder 18 is fixedly connected to a spring 19, and the end of the spring 19 away from the auxiliary cylinder 18 is fixedly connected to the side of the auxiliary protrusion 20.

Through the cooperation of the spring 19 and the auxiliary cylinder 18, the spring 19 pushes the auxiliary protrusion 20 to move in the inner wall of the auxiliary cylinder 18, and then the convex surface of the auxiliary protrusion 20 fits against the concave surface of the auxiliary groove 10, thereby stabilizing and limiting the toothed plate 5.

[0030] In a preferred embodiment, there are three adjusting rods 16, and the outer edges of the three adjusting rods 16 are rotatably sleeved with the inner wall of the auxiliary plate 11. The connection structure on the side of the three adjusting rods 16 is completely consistent.

By adding the auxiliary plate 11, it is convenient to use a single auxiliary plate 11 to assist the connection of the three adjusting rods 16.

[0031] Working principle: When the device is in use, the side of the docking plate 3 is slidably docked with the inner wall of the docking frame 2. Then, the adjusting rod 16 drives the outer edge of the limiting plate 15 through the inner walls of the first slide groove 12 and the second slide groove 13 to the inner wall of the limiting groove 14. Then, the adjusting rod 16 is rotated, thereby driving the outer edge of the limiting plate 15 to be limited with the inner wall of the limiting groove 14, thus helping the docking plate 3 to be stably limited in the inner wall of the docking frame 2. The electric telescopic rod 4 drives the toothed plate 5 to move, thereby driving the gear 7 to rotate, and then driving the camera 9 to adjust its angle. The servo motor 8 drives the camera 9 to adjust its angle, thus facilitating the auxiliary device to adapt to the angle of the road crack. The spring 19 pushes the auxiliary protruding rod 20 to move in the inner wall of the auxiliary cylinder 18, thereby using the convex surface of the auxiliary protruding rod 20 to fit with the concave surface of the auxiliary groove 10, thus assisting the toothed plate 5 to be limited, and thus assisting the camera 9 to be angle limited.
