[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the utility model provides a technical solution: a bridge bottom surface crack detection device, including an equipment fixing bracket 1, two first slide grooves 5 are provided on the equipment fixing bracket 1, and a bidirectional threaded screw rod 7 is rotatably connected inside the two first slide grooves 5 respectively. The two bidirectional threaded screw rods 7 are threadedly connected to a corresponding sliding clamp 6 at the opposite ends of the threads on both sides. One end of the two bidirectional threaded screw rods 7 extends outward from the first slide groove 5, and a first pulley 8 and a second pulley 9 are respectively provided on the protruding part of the rod body, and the first pulley 8 and the second pulley 9 are connected by a synchronous belt 10, and one end of the bidirectional threaded screw rod 7 close to the first pulley 8 is connected to the output end of the first motor 3.

[0025] In this embodiment, the threads on both sides of the bidirectional threaded screw 7 are in opposite directions and are each connected to a sliding clamp 6. When the first motor 3 drives the bidirectional threaded screw 7 to rotate, the sliding clamps 6 on both sides can move toward or away from each other at the same time, thereby quickly and firmly fixing the equipment fixing bracket 1 on the bridge. In addition, the two bidirectional threaded screws 7 are linked by the first pulley 8, the second pulley 9 and the synchronous belt 10 to achieve synchronous power transmission, ensuring that the two pairs of sliding clamps 6 can clamp objects at the same time, so that they can quickly fix themselves, and the installation is relatively quick and convenient. In addition, this screw clamping method provides a more stable and reliable fixing effect compared to many cylinder fixing structures.

[0026] A second slide groove 12 is provided on the side of the equipment fixing bracket 1 away from the first slide groove 5, and a second motor 13 is provided inside the second slide groove 12. The output end of the second motor 13 is connected to a one-way threaded screw 14, and a slider 15 is threadedly connected to the one-way threaded screw 14. The slider 15 is slidably connected in the second slide groove 12.

[0027] In this embodiment, driven by the second motor 13, the one-way threaded screw 14 starts to rotate, thereby driving the slider 15 threadedly connected to it to move axially along the one-way threaded screw 14. The movement of the slider 15 is guided and fixed by the second slide groove 12 to ensure that it can only move horizontally in the second slide groove 12. Therefore, the one-way threaded screw 14 can effectively drive the slider 15 and the third motor 17 at the bottom to move left and right in the horizontal direction, thereby realizing flexible position adjustment.

[0028] A fixing plate 16 is provided on the side of the slider 15 away from the second slide groove 12, and a third motor 17 is installed on the side of the fixing plate 16 away from the slider 15. A rotating shaft 18 is connected to the output end of the third motor 17, and a camera mechanism 19 is installed on the end of the rotating shaft 18 away from the third motor 17. The one-way threaded screw 14 is rotatably connected to the inner wall of the second slide groove 12 at one end away from the second motor 13.

[0029] In this embodiment, the third motor 17 drives the rotating shaft 18 to rotate, thereby driving the camera mechanism 19 to rotate accordingly, so that the detection angle of the camera can be easily adjusted. At the same time, the second motor 13 is cooperated to enable the camera mechanism 19 to achieve horizontal left and right displacement, thereby significantly improving the detection range of the device. This comprehensive adjustment method not only enhances the flexibility of detection, but also reduces the number of required detection devices, effectively reducing the detection cost.

[0030] An anti-slip groove 11 is provided at the junction of the first slide groove 5 and the sliding clamp plate 6, a motor mounting plate 2 is provided on the outside of the equipment fixing bracket 1, a first motor 3 is installed on the motor mounting plate 2, and the first slide groove 5 is fixed to the equipment fixing bracket 1 through a support rod 4.

[0031] In this embodiment, the design of the anti-drop groove 11 can ensure that the sliding clamp plate 6 will not accidentally fall off or slide out when moving in the first sliding groove 5, thereby improving stability and safety.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
