Description

Technical Field

[0001] This invention relates to the field of bridge inspection equipment technology, specifically to a bridge asphalt pavement crack detection device. Background Technology

[0002] Over long-term use, asphalt pavement on bridges is prone to cracks and other defects due to vehicle loads and environmental factors (such as temperature changes and rainwater erosion). If cracks are not detected and repaired in time, they will gradually expand, affecting the load-bearing capacity and service life of the bridge pavement, and even causing safety hazards.

[0003] Currently, bridge asphalt pavement crack detection is mostly carried out using large-scale testing equipment. However, large-scale testing equipment is bulky, lacks flexibility, and is difficult to adapt to complex bridge pavement environments. In addition, the equipment has high operating costs, which is not conducive to large-scale promotion and use. This paper proposes a bridge asphalt pavement crack detection device that can adapt to complex pavement environments. Summary of the Invention

To achieve the above objective, this invention provides the following technical solution: a bridge asphalt pavement crack detection device, including a mounting frame; A steering assembly, comprising a motor, which is fixedly connected to the top inside the mounting bracket. A rotating shaft is fixedly connected to the transmission end of the motor, and a gear is fixedly connected to the other end of the rotating shaft. A rack is driven to the outside of the gear, and a support frame is rotatably connected to the opposite side of the rack. A rotating rod is rotatably connected to the bottom of each of the two support frames. The connecting assembly includes two support rods, which are fixedly connected to the top of the mounting frame. Rotating rings are rotatably connected to each of the two support rods. The device features a compact design, making it easier to access narrow areas, curves, and corners of bridge surfaces compared to traditional large-scale testing equipment. No additional modifications to the testing environment are required. With the coordinated action of the steering and power components, steering adjustment is smooth and responsive.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figures 1-6 The present invention provides a technical solution: a bridge asphalt pavement crack detection device, including a mounting frame 1; Steering assembly 2 includes a motor 201, which is fixedly connected to the top of the mounting bracket 1. A rotating shaft 202 is fixedly connected to the transmission end of the motor 201, and a gear 203 is fixedly connected to the other end of the rotating shaft 202. A rack 204 is drivenly connected to the outer side of the gear 203. Support brackets 205 are rotatably connected to opposite sides of the rack 204. Rotating rods 206 are rotatably connected to the bottom of the two support brackets 205. When the device needs to adjust its direction of movement, the control box 9... A steering signal is sent to the motor 201 of the steering assembly 2. The motor 201 is fixed inside the top of the mounting bracket 1. Its transmission end drives the rotating shaft 202 to rotate, and the gear 203 at the other end of the rotating shaft 202 rotates together. Since the gear 203 is connected to the outside of the rack 204, the rotation of the gear 203 will drive the rack 204 to move in the horizontal direction. The support brackets 205 on both sides of the rack 204 move synchronously with the rack 204, thereby driving the rotating rod 206 at the bottom of the support bracket 205 to move.

[0018] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the connecting assembly 3 includes two support rods 301, which are fixedly connected to the top of the mounting frame 1. Rotating rings 302 are rotatably connected to each of the two support rods 301. The connecting assembly 3 also includes two connecting rods 303, whose ends are fixedly connected to the sides of the two support rods 301 and the rotating rod 206. Connecting rods 304 are fixedly connected to the side surfaces of the two rotating rings 302, and wheels 305 are rotatably connected to the opposite sides of the two connecting rods 304. A detection assembly 4 is installed inside the mounting frame 1. Meanwhile, in the connecting assembly 3, the support rods 301... 1. Fixed inside the top of the mounting frame 1, the rotating rod 206 and the rotating ring 302 on the side surface of the support rod 301 can assist the rotating rod 206 in adjusting its angle, and the connecting rod 303 on the side of the support rod 301 and the rotating rod 206 that is close to each other can enhance the stability of their connection; the connecting rod 304 on the side surface of the rotating ring 302 changes direction as the angle of the rotating rod 206 is adjusted, and finally drives the wheel 305 on the opposite side of the connecting rod 304 to turn. With the power output of the wheel 304, the device's movement direction can be flexibly adjusted, so that it can operate in a relatively complex road environment and ensure that the device can cover different areas of road detection.

[0019] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the detection component 4 includes a detector body 401, which is fixedly connected to the top inside the mounting frame 1. A detection groove 402 is provided at the bottom of the mounting frame 1. A support base 403 is fixedly connected to the top of the mounting frame 1, and a camera 404 is fixedly connected to the bottom of the support base 403. A power component 5 is installed inside the mounting frame 1. During device movement, the control box 9 synchronously starts the detection component 4. The detector body 401, fixed to the top inside the mounting frame 1, can contact or scan the asphalt pavement below through the detection groove 402 at the bottom of the mounting frame 1, collecting pavement structure data in real time and identifying information such as the location, width, and length of cracks. Simultaneously, the camera 404 at the bottom of the support base 403 at the top of the mounting frame 1 is activated to capture images of the pavement, recording the actual condition of the pavement. This data complements the detection data from the detector body 401, further improving the accuracy of crack detection. The detection data and image information can be transmitted to the control box 9 in real time for storage or processing, completing the automated detection of cracks in the asphalt pavement of the bridge.

[0020] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the power assembly 5 includes two support frames 501, which are fixedly connected inside the mounting frame 1. Rotating grooves 502 are respectively opened on opposite sides of the two support frames 501. Rotating rods 503 are rotatably connected inside the rotating grooves 502 via bearings. Wheels 504 are fixedly connected to opposite ends of the rotating rods 503. A bevel gear 505 is fixedly connected to the side surface of the rotating rod 503. A mounting groove 506 is provided on the top of the bevel gear 505, which is located on the top of the mounting frame 1. A fixing frame 6 is fixedly connected inside the mounting groove 506. A motor 7 is fixedly connected to one side of the fixing frame 6. A bevel gear 8 is fixedly connected to the transmission end of the motor 7. The outer side of bevel gear 8 meshes with the outer side of bevel gear 3 505. When the device needs to move on the road surface, the control box 9 sends a start signal to motor 2 7. Motor 2 7 is fixed on the fixed frame 1 6 in the mounting slot 506, and its transmission end drives bevel gear 8 to rotate. Since bevel gear 8 meshes with bevel gear 3 505 on the side surface of rotating rod 2 503 in power assembly 5, the rotation of bevel gear 8 will synchronously drive bevel gear 3 505 to rotate, thereby driving rotating rod 2 503 to rotate in the rotating slot 502 of support frame 2 501 with the assistance of bearings. The wheels 2 504 at opposite ends of rotating rod 2 503 rotate together with rotating rod 2 503, providing the device with forward or backward power, realizing the device's autonomous movement on the asphalt road surface.

[0021] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a control box 9 is fixedly connected to the top of the mounting frame 1. The control box 9 is electrically connected to motor 201, detector body 401, camera 404, and motor 7. A fixing frame 10 is fixedly connected to the top of the mounting frame 1. A photovoltaic panel 11 is fixedly connected to the top of the fixing frame 10. The photovoltaic panel 11 is electrically connected to the control box 9. The photovoltaic panel 11 on the top of the device can convert solar energy into electrical energy and transmit the electrical energy to the energy storage module in the control box 9 for storage, providing clean energy for the operation of the entire device. At the same time, the control box 9, as the core control unit, establishes an electrical connection with motor 201, detector body 401, camera 404, and motor 7, and can accurately control the start-up and shutdown and operating parameters of each electrical component, ensuring the stability and controllability of the device operation.

[0022] The method of use and advantages of this invention: The working process of this bridge asphalt pavement crack detection device is as follows: like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the photovoltaic panel 11 on the top of the device converts solar energy into electrical energy and transmits it to the energy storage module in the control box 9 for storage, providing clean energy for the operation of the entire device. Meanwhile, the control box 9, as the core control unit, establishes electrical connections with motor 201, the detector body 401, the camera 404, and motor 7, enabling precise control of the start / stop and operating parameters of each electrical component, ensuring the stability and controllability of the device operation. When the device needs to move on the road, the control box 9 sends a start signal to motor 7. Motor 7 is fixed on the mounting bracket 6 in the mounting slot 506, and its transmission end drives the bevel gear 8 to rotate. Because the bevel gear 8 meshes with the bevel gear 505 on the side surface of the rotating rod 503 in the power component 5, the rotation of the bevel gear 8... The motion synchronously drives the bevel gear 3 505 to rotate, which in turn drives the rotating rod 2 503 to rotate within the rotating groove 502 of the support frame 2 501 via bearing assistance. The wheels 2 504 at opposite ends of the rotating rod 2 503 rotate together with the rotating rod 2 503, providing the device with forward or backward power, enabling the device to move autonomously on the asphalt road surface. When the device needs to adjust its direction of movement, the control box 9 sends a steering signal to the motor 1 201 of the steering assembly 2. The motor 1 201 is fixed inside the top of the mounting frame 1, and its transmission end drives the rotating shaft 202 to rotate. The gear 1 203 at the other end of the rotating shaft 202 rotates together. Since the gear 1 203 is connected to the outer side of the rack 204, the rotation of the gear 1 203 will drive the rack 204 to move horizontally. As the rack 204 moves, the support frames 205 on both sides opposite to the rack 204 move synchronously with the rack 204, thereby causing the rotating rod 206 at the bottom of the support frame 205 to shift. Simultaneously, in the connecting assembly 3, the support rod 301 is fixed to the top inside the mounting frame 1. The rotating rod 206 and the rotating ring 302 on the side surface of the support rod 301 can assist in adjusting the angle of the rotating rod 206. Furthermore, the connecting rod 303 on the side of the support rod 301 and the rotating rod 206 that is close together can enhance the stability of their connection. The connecting rod 304 on the side surface of the rotating ring 302 changes direction as the angle of the rotating rod 206 is adjusted, ultimately causing the wheel 305 on the side opposite to the connecting rod 304 to turn. Combined with the power output of the wheel 304, this allows for flexible adjustment of the device's direction of movement. To ensure the device can cover different areas of road surface inspection, during the device's movement, the control box 9 simultaneously activates the detection component 4. The detector body 401 is fixed inside the top of the mounting frame 1, and its detection end can contact or scan the asphalt pavement below through the detection slot 402 opened at the bottom of the mounting frame 1 to collect pavement structure data in real time and identify information such as the location, width, and length of cracks. At the same time, the camera 404 at the bottom of the support base 403 at the top of the mounting frame 1 is activated simultaneously to capture images of the road surface and record the actual condition of the road surface, which complements the detection data of the detector body 401 and further improves the accuracy of crack detection. The detection data and image information can be transmitted to the control box 9 in real time for storage or processing to complete the automated detection of cracks in the asphalt pavement of the bridge.
