[0041] In view of the problems existing in the above related technologies, this embodiment provides a bridge detection device.

[0042] As Figure 1 and Figure 2 shown, a bridge detection device provided by an embodiment of the present utility model includes a camera 5, a rotating mechanism 2, a moving seat 3 and an inspection bracket 4;

[0043] The inspection support 4 is used to move along the length direction of the bridge 1, such as Figure 1 the direction of the x-axis in the figure, and the extending direction of the inspection support 4 is the width direction of the bridge 1, such as Figure 2 the direction of the y-axis in the figure; the moving seat 3 is arranged on the inspection support 4, and the moving seat 3 is used to move along the extending direction of the inspection support 4; the camera 5 is connected to the moving seat 3 through the rotating mechanism 2; when the moving seat 3 moves along the extending direction of the inspection support 4, the rotating mechanism 2 is used to synchronously drive the camera 5 to rotate to obtain the image information of the bottom of the bridge. For example, when the moving seat 3 moves in the negative direction of the x-axis, the rotating mechanism 2 drives the camera 5 to rotate so that the camera 5 faces obliquely upward in the positive direction of the x-axis to obtain the image information of the bottom of the bridge 1. At this time, the image range of the bottom of the bridge obtained by the camera 5 is as shown by Figure 3 the visible range α of the right camera 5 in the figure. Similarly, when the moving seat 3 runs to the other end of the inspection support 4, the rotating mechanism 2 drives the camera 5 to face obliquely upward in the negative direction of the x-axis to obtain the image information of the bottom of the bridge 1. At this time, the image range of the bottom of the bridge obtained by the camera 5 is as shown by Figure 3 the visible range β of the left camera 5 in the figure. Then the moving seat 3 moves in the positive direction of the x-axis to move the moving seat 3 back to the initial position.

[0044] It should be noted that the rotating mechanism 2 in this embodiment usually drives the camera 5 to make a 360° rotation on the horizontal plane. The rotation effect of the rotating mechanism 2 is as shown by Figure 4 in the figure to ensure that the acquisition range of the camera 5 is at the bottom of the bridge 1. If, for example, the rotation angle of a panoramic camera 5 is adopted, it may cause the camera 5 to rotate too much during the movement, resulting in too much interference image information being acquired, which affects the judgment of the subsequent inspection results of the bridge 1.

[0045] In this embodiment, during use, the inspection support 4 plays a supporting role for the moving seat 3 to ensure the normal operation of the moving seat 3. The moving seat 3 drives the camera 5 to move to obtain the image information of the bottom of the bridge. The moving seat 3 drives to move along the extending direction of the inspection support 4, and the rotating mechanism 2 synchronously drives the camera 5 to rotate to make the acquisition of the image information of the bottom of the bridge more comprehensive. At the same time, the inspection support 4 can move along the length direction of the bridge 1 to drive the moving seat 3, the rotating mechanism 2 and the camera 5 to move along the length direction of the bridge 1 to obtain the image information of the bottom of the entire bridge 1 for an overall inspection of the bridge 1. And the inspection process does not require manual operation, effectively improving the inspection safety (for example, avoiding the safety problems brought by manual inspection in harsh weather such as high temperature and strong wind), reducing the problems of missed inspection and repeated inspection caused by manual fatigue or visual limitations, and improving the comprehensiveness of the quality inspection of the bottom of the bridge 1.

[0046] Optionally, the rotating mechanism 2 includes a rotating shaft 21 and a driving motor connected to each other; a connecting seat is provided at the upper end of the moving seat 3;

[0047] The driving motor is mounted on the connecting seat, the rotating shaft 21 is connected to the driving motor, and the camera 5 is mounted on the top end of the rotating shaft 21 .

[0048] Specifically, the driving motor is arranged on the connecting seat, one end of the rotating shaft 21 is connected to the driving motor, and the other end is connected to the camera 5. When in use, the driving motor runs to drive the rotating shaft 21 to rotate, and the rotating shaft 21 drives the camera 5 to rotate to obtain the bottom image information of the bridge from more angles (for example, close-up and long-range views at the same position, looking up at the same position, looking up at an angle, etc.) to increase the accuracy of the subsequent judgment of the inspection results of the bridge 1.

[0049] Optionally, the movable seat 3 includes a support rod 31 and a base 32 , the rotating mechanism 2 is disposed at the upper end of the support rod 31 , and the lower end of the support rod 31 is connected to the base 32 .

[0050] Specifically, Figure 2 As shown, the support rod 31 is used to reduce the distance between the camera 5 and the bottom of the bridge 1, so as to obtain more accurate bottom image information of the bridge 1.

[0051] Optionally, the support rod 31 includes a first support rod 311 and a second support rod 312 which are hollow inside, the bottom of the second support rod 312 is connected to the base 32, the outer diameter of the second support rod 312 is equal to the inner diameter of the first support rod 311, the first support rod 311 is sleeved on the second support rod 312, and a locking mechanism 6 is provided at the junction of the second support rod 312 and the first support rod 311.

[0052] Specifically, Figure 5 As shown, the first support rod 311 is sleeved on the second support rod 312, and a locking mechanism 6 is provided at the intersection of the second support rod 312 and the first support rod 311. When it is necessary to reduce or increase the distance between the camera 5 and the bottom of the bridge 1, the locking mechanism 6 is used to adjust the total length of the first support rod 311 and the second support rod 312, so that the bridge inspection device can be adjusted according to different inspection environments, thereby increasing the versatility of the bridge inspection device.

[0053] Optionally, the locking mechanism 6 includes a first connecting hole 61 and a second connecting hole 62, wherein a plurality of the first connecting holes 61 are spaced apart along the length direction of the second support rod 312, and a plurality of the second connecting holes 62 are spaced apart along the length direction of the first support rod 311, and the first connecting hole 61 and the second connecting hole 62 are used to be connected by a pin 7.

[0054] Specifically, second connection holes 62 and first connection holes 61 that match each other are provided at intervals along the lengths of the first support rod 311 and the second support rod 312. When it is necessary to adjust the lengths of the first support rod 311 and the second support rod 312, the corresponding first connection holes 61 and second connection holes 62 are aligned, and are connected and fixed by a pin 7 to lock the lengths of the adjusted first support rod 311 and second support rod 312. As Figure 5 shown, Figure 5 in (a) is a schematic structural diagram when the first support rod 311 and the second support rod 312 are all extended, Figure 5 and in (b) is the first support rod 311 and the second support rod 312 after being connected and fixed by the pin 7.

[0055] Optionally, the support rod 31 further includes an electric motor. The electric motor is arranged on the base 32, and the electric motor is connected to the bottom of the second support rod 312. The electric motor is used to drive the second support rod 312 to rotate; the second support rod 312 is a screw rod, the locking mechanism 6 is a nut, the nut is threadedly connected to the screw rod, and the upper end of the nut abuts against the lower end of the first support rod 311.

[0056] Specifically, as Figure 6 shown, this is another specific structure of the support rod 31 and the locking mechanism 6 according to an embodiment of the present invention, and a ball screw can be referred to. The second support rod 312 is connected to the base 32 to ensure that the second support rod 312 does not tilt during operation. The electric motor is connected to the second support rod 312 and is used to drive the second support rod 312 to rotate. At this time, the locking mechanism 6, that is, the nut, will move upward or downward according to the rotation direction of the second support rod 312 (i.e., the screw rod), and the first support rod 311 that abuts against the nut will also move upward or downward as the nut moves upward or downward, realizing the adjustment of the length of the support rod 31. The support rod 31 and the locking device of this embodiment do not require manual operation, further increasing the inspection efficiency and safety of the bridge 1.

[0057] In addition, a distance measuring sensor can be arranged on the top of the camera 5 to obtain the distance between the camera 5 and the bottom of the bridge 1 in real time, so as to accurately adjust the height of the support rod 31 while avoiding the collision between the camera 5 and the bottom of the bridge 1 and reducing the maintenance cost.

[0058] Optionally, the number of the moving seats 3 is two, and the camera 5 is arranged on each of the moving seats 3. The two moving seats 3 are symmetrically arranged at both ends of the inspection bracket 4, and the two moving seats 3 are used to move towards or away from each other simultaneously.

[0059] Specifically, as Figure 1As shown, there are two movers 3, including a mover 3 disposed on the right side and a mover 3 disposed on the left side. Taking the middle line of the inspection bracket 4 as the demarcation line, the two movers 3 move towards or away from each other simultaneously to improve the acquisition efficiency of the image information of the bridge bottom. It should be noted that two support rods 31 can be provided on each mover 3, and a camera 5 is provided on each support rod 31. Correspondingly, in this embodiment, there are two movers 3, 4 support rods 31 and 4 cameras 5, which can obtain the image information of the bridge bottom from more angles and with more details.

[0060] Optionally, distance measuring sensors facing each other are provided at the tops of the two movers 3, and the distance measuring sensors are used to measure the distance between the two movers. This can prevent the two movers 3 from colliding during operation.

[0061] Optionally, the bridge inspection device further includes a master control platform and a display;

[0062] The master control platform is connected to the camera 5, the rotating mechanism 2 and the mover 3, and the display is connected to the camera 5.

[0063] Specifically, the master control platform can be used to obtain the image information of the bridge bottom acquired by the camera 5, control the operation of the rotating mechanism 2 and the mover 3. The master control platform can also be provided with an image processing module for processing the image information of the bridge bottom acquired by the camera 5 to generate the quality inspection result of the bridge 1 in real time.

After the mover 3 completes one cycle of operation, the moving device moves a preset distance along the length direction of the bridge 1 to drive the inspection bracket 4 to move a preset distance along the length direction of the bridge 1 for the quality inspection of the next position of the bridge 1 bottom. The coordinated use of the moving device, the mover 3, the rotating device and the camera 5 realizes the quality inspection without dead angles in both the width direction and the length direction of the bridge 1.

[0066] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will all fall within the protection scope of the present invention.
