Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0029] As Figure 1 shown, it is a schematic diagram of the overall structure of the bridge quality detection device of the present invention. The bridge quality detection device of the present invention is provided with a positioning mechanism, a height adjustment mechanism, a position adjustment mechanism, and a detection mechanism. The positioning mechanism is provided with a first bending plate 11 and a second bending plate 12. A part of the first bending plate 11 and the second bending plate 12 overlap. Specifically, a card slot 111 is provided on the inner side wall of the first bending plate 11. The side plate of the second bending plate 12 is located in the card slot 111. An inner concave strip 112 is provided in the card slot 111. A convex strip 121 is provided on the outer side wall of the second bending plate 12. The convex strip 121 slides in the inner concave strip 112.

[0030] Please refer to Figure 1 and Figure 2As shown in the figure, the height adjustment mechanism of the present invention is provided with a housing 21 and a first driving assembly. The housing 21 is fixed to the top of the second bending plate 12. The number of the first bending plate 11, the second bending plate 12, the housing 21 and the first driving assembly is two. The first driving assembly is used to adjust the effective height of the first bending plate 11 and the second bending plate 12. Specifically, the first driving assembly is provided with a first servo motor 22, a coupling 23, a driving gear 24, a driven gear 25, a first positioning plate 26, a second positioning plate 27 and a rotating rod 28. The first servo motor 22, the coupling 23 and the driving gear 24 are connected in sequence. The driving gear 24 meshes with the driven gear 25. The driven gear 25 is finally driven to rotate by the first servo motor 22. The first positioning plate 26 is fixed to the outer wall of the first bending plate 11. The second positioning plate 27 is fixed to the upper end of the outer wall of the second bending plate 12. The first positioning plate 26 is provided with a threaded hole. The second positioning plate 27 is provided with a positioning hole. The lower end of the rotating rod 28 is provided with an external thread 281.

The upper end of the rotating rod 28 passes through the positioning hole and is rotatably connected to the central axis of the driven gear 25. The external thread 281 is matched with the threaded hole. As the driven gear 25 rotates, the rotating rod 28 can be driven to rotate around its central axis. Thus, the position of the first positioning plate 26 on the external thread 281 can be adjusted, and finally the position of the second bending plate 12 on the first bending plate 11 can be adjusted, thereby realizing the adjustment of the effective height of the two. During this adjustment process, since the first servo motor 22 is fixed to the top surface of the second bending plate 12, and with the mutual cooperation of the convex strip 121 and the concave strip 112, the second bending plate 12 can move stably in the card slot 111 of the first bending plate 11.

[0031] Please continue to refer to Figure 1 and Figure 2 As shown in the figure, a support column 13 is vertically provided at the bottom surface of the outer end of the second bending plate 12 of the present invention.

During the detection process, the moving wheel 14 moves on the upper end surface of the bridge, and the "C"-shaped structure formed by the first bending plate 11 and the second bending plate 12 can be located on the guardrails or enclosures on both sides of the bridge. By adjusting the effective height of the first bending plate 11 and the second bending plate 12 to adjust the height of the lower detector 42, it can also adapt to the use of bridge guardrails or fences of different heights.

The accommodation groove 31 includes an open end and a closed end. The closed end of the accommodation groove 31 is fixedly connected to the outer end of the corresponding first bending plate 11. The second driving component is located in the corresponding accommodation groove 31. The second driving component includes a rack 32, a spur gear 33, a second servo motor 34, a guide plate 35 and a connecting piece 36. The rack 32 is fixed on the bottom surface of the accommodation groove 31. The spur gear 33 meshes with the rack 32. The output end of the second servo motor 34 is rotatably connected to the spur gear 33. The second servo motor 34 is fixed on the guide plate 35. The guide plate 35 can move on the inner bottom surface of the accommodation groove 31. Specifically, the guide plate 35 is provided with sliders 351, and the bottom surface of the accommodation groove 31 is provided with sliding grooves 311. The sliders 351 are stuck in the sliding grooves 311 and can move.

In this embodiment, the number of the sliding grooves 311 is two, and the number of the sliders 351 is four. The four sliders 351 are respectively located at the corner positions of the lower bottom surface of the guide plate 35 or are separately located on both side surfaces of the guide plate 35 in pairs.

[0033] Please continue to refer to Figure 3 As shown in the figure, the connecting piece 36 of the present invention is composed of a first moving groove 361, a second moving groove 362 and a spring 363. The two ends of the spring 363 are respectively hinged to the inner bottom parts of the first moving groove 361 and the second moving groove 362. The first moving groove 361 is connected to the outer side central axis position of the spur gear 33, and the second moving groove 362 is connected to the side surface of the support plate 41.

[0034] In addition, as Figure 4 shown in the figure, the detection mechanism of the present invention is provided with a support plate 41, a moving component and a detector 42. The moving component and the detector 42 are located on the support plate 41. The two ends of the support plate 41 are respectively located in the corresponding accommodation grooves 31 and are connected to the corresponding second driving components. The second driving components can adjust the position of the support plate 41. The moving component is provided with mounting plates 431, rotating shafts 432, third servo motors 433, rotating gears 434, transmission chains 435 and moving plates 436. The number of the mounting plates 431 is four and they are respectively vertically fixed at the top corners of the support plate 41. The number of the rotating shafts 432 is two, which are respectively located at the two ends of the support plate 41 and are rotatably located between the mounting plates 431. The output end of the third servo motor 433 is rotatably connected to any one of the rotating shafts 432. In addition, the number of the rotating gears 434 is four, and the rotating gears 434 are respectively fixedly sleeved on the outer peripheral walls at both ends of the rotating shafts 432. The number of the transmission chains 435 is two, and the transmission chains 435 are sleeved on the rotating gears 434 along the length direction of the mounting plates 431. The moving plate 436 is fixed on the transmission chains 435.

[0035] During the use of the detection mechanism of the present invention, the third servo motor 433 drives any one of the transmission chains 435 to rotate on the rotating gear 434, and the other transmission chain 435 also starts to move. Since the moving plate 436 is fixed to the two transmission chains 435, during the transmission of the two transmission chains 435, the moving plate 436 will also move. Thus, the detector 42 above it can achieve the purpose of detecting different positions at the bottom of the bridge.

[0036] Preferably, the device of the present invention is further provided with a controller and a plurality of cameras, lidar, etc. These electronic devices cooperate with each other to measure the curvature of the bridge in front of the entire device. These electronic components are all prior arts, or the above functions can be realized through simple code editing. The detection signals are sent to the controller, and the controller can obtain the arc data of the bridge in front according to this information, send a signal command to the second servo motor 34, and the second servo motor 34 drives the spur gear 33 to adjust its position on the rack 32, thereby adjusting the angle of the support plate 41. Whether the bridge in front of the device is a leftward curved arc or a rightward curved arc, the rotation angle of the support plate 41 can be adjusted by the two second servo motors 34.

[0037] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments.
