[0017] Reference Figures 1 to 3 As shown, this embodiment provides a bridge structure surface crack detection device, including a top panel with telescopic function, a movable block 6 slidably disposed on the bottom surface of the top panel, a camera 7 installed on the bottom surface of the movable block 6, lifting components installed at the four corners of the bottom surface of the top panel, a walking component installed at the bottom end of the lifting component, and a moving drive component connected to the movable block 6, the moving drive component being installed on the top panel.

[0018] This invention uses a lifting component to raise the top panel to a suitable position, ensuring that the normal operation of vehicles below is not affected during the inspection process. Combined with a traveling component, the device can move along the length of the bridge. Furthermore, the movable camera allows for a comprehensive scan of the entire top surface of the bridge. The camera transmits the images to an image analysis device, which analyzes and processes the images to detect cracks and facilitates timely repairs.

[0019] The scheme is further optimized. The moving drive component includes a lead screw 5. One end of the lead screw 5 is rotatably connected to the first mounting block 3, and the other end of the lead screw 5 is rotatably connected to the second mounting block 4. The lead screw 5 is shaft-connected to a movable block drive motor 601, which is mounted on the second mounting block 4. The external thread of the lead screw 5 is rotatably connected to the first mounting block 3, and the movable block 6 is threadedly engaged with the lead screw 5.

[0020] By controlling the operation of the movable block drive motor 601, the movable block drive motor 601 drives the lead screw 5 to rotate, the lead screw 5 drives the movable block 6 to move, and the movable block 6 drives the camera 7 to move. When the device does not move, it can realize the image capture and detection of a certain area in one direction.

[0021] The scheme is further optimized. The top panel includes a first top plate 1, a second top plate 2 is horizontally slidably inserted into the first top plate 1, a first mounting block 3 is fixedly connected to the bottom edge of the second top plate 2, and a second mounting block 4 is fixedly connected to the bottom edge of the first top plate 1.

[0022] The way the first top plate 1 and the second top plate 2 are matched allows their top and bottom surfaces to be on the same plane, thus ensuring the smooth horizontal movement of the movable block 6.

[0023] The scheme is further optimized. The lifting component includes lifting rods 8, which are vertically arranged. The movable ends of two lifting rods 8 are fixedly connected to the bottom edge of the second top plate 2, and the other two lifting rods 8 are fixedly connected to the bottom edge of the first top plate 1. The walking component is installed at the bottom end of the lifting rods 8.

[0024] By controlling the synchronous raising and lowering of multiple lifting poles 8, the first roof plate 1 and the second roof plate 2 can be raised and lowered synchronously, providing clearance for vehicles operating below.

[0025] The design is further optimized so that the walking component includes a walking leg 9 installed at the bottom of the lifting rod 8. A first gear 10, a second gear 11, and a third gear 12 are rotatably connected inside the walking leg 9. The first gear 10 meshes with the second gear 11, and the second gear 11 meshes with the third gear 12. The first gear 10 is shaft-connected to a walking motor 14, which is fixedly connected to the walking leg 9. The third gear 12 is shaft-connected to a walking wheel 13.

[0026] By controlling the operation of the walking motor 14, the walking motor 14 drives the first gear 10 to rotate, the first gear 10 drives the second gear 11 to rotate, the second gear 11 drives the third gear 12 to rotate, and the third gear 12 drives the walking wheel 13 to rotate, thereby realizing the function of the equipment moving on the bridge surface.

[0027] In a further optimized design, the first top plate 1 and the second top plate 2 are connected by several horizontal plates. The side wall of the horizontal plate is fixedly connected with a first dovetail key 17. The side wall of the adjacent horizontal plate is provided with a dovetail groove, and the dovetail groove slides in conjunction with the first dovetail key 17.

[0028] This configuration allows for relative movement between the first top plate 1 and the second top plate 2, enabling the overall width of the equipment to be increased or decreased to accommodate different bridge deck widths.

[0029] In a further optimized design, an unfolding motor 16 is installed on the horizontal plate at the edge. The shaft of the unfolding motor 16 is connected to a fourth gear 15. The fourth gear 15 is rotatably connected to the corresponding horizontal plate and meshes with the corresponding first dovetail key 17.

[0030] By controlling the operation of the unfolding motor 16, the unfolding motor 16 drives the fourth gear 15 to rotate, and the fourth gear 15 drives the first dovetail key 17 to move, so that the first top plate 1 and the second top plate 2 can unfold or retract with each other.
