[0019] As Figures 1-4 shown, the present utility model provides a bridge crack detection device, including a vehicle body 1. A fixed frame 11 is fixedly arranged at the top of the vehicle body 1 for fixed connection. A first rotating frame 12 is rotatably installed on the outside of the fixed frame 11. A telescopic frame 2 is installed on the outside of the first rotating frame 12. One end of the telescopic frame 2 away from the first rotating frame 12 is rotatably installed with a second rotating frame 21. The rotation of the second rotating frame 21 facilitates the folding and unfolding of the vision detector body 23. A vision detector body 23 is installed at the top of the second rotating frame 21. A threaded rod 24 is rotatably inserted in the first rotating frame 12. A threaded slider 25 is fixedly sleeved on the outside of the threaded rod 24. The threaded slider 25 is fixedly connected with the telescopic frame 2. The telescopic frame 2 is movably sleeved on the outside of the first rotating frame 12. An electric slider 22 is installed at the top of the second rotating frame 21. The vision detector body 23 is installed on the top of the electric slider 22, so that the electric slider 22 can drive the vision detector body 23 to move. Both the first rotating frame 12 and the second rotating frame 21 are driven by motors.

[0020] An installation frame 3 is fixedly arranged on the outside of the electric slider 22. A worm 31 is rotatably arranged in the installation frame 3. A rotating rod 32 is rotatably inserted through the electric slider 22. The vision detector body 23 is installed on the outside of the rotating rod 32. A worm gear 33 is fixedly sleeved on the outside of the rotating rod 32. The worm 31 meshes with the worm gear 33.

[0021] By adopting the above technical solution, the end of the output shaft of the second motor 34 rotates to drive the worm 31 to rotate. The rotation of the worm 31 drives the meshing worm gear 33 to rotate. The rotation of the worm gear 33 drives the rotating rod 32 to rotate. The rotation of the rotating rod 32 drives the vision detector body 23 to rotate, so that adjustment can be carried out, which is convenient for observing and detecting positions that are not easy to observe.

[0022] A counterweight 14 is installed in the vehicle body 1.

[0023] By adopting the above technical solution, the vehicle body 1 is made more stable.

[0024] A detection box 13 is installed at the top of the vehicle body 1.

[0025] By adopting the above technical solution, the detection box 13 can analyze the data detected by the vision detector body 23.

[0026] On the outer side of the second rotating frame 21, a support frame 27 is installed, and a blower 28 is rotatably provided inside the support frame 27.

[0027] By adopting the above technical solution, the blower 28 can blow off the dust adhering to the bottom end of the bridge, avoiding problems such as unclear detection.

[0028] On the side of the vehicle body 1, a pulley 15 is installed.

[0029] By adopting the above technical solution, the vehicle body 1 can move through the pulley 15.

[0030] Inside the first rotating frame 12, a first motor 26 is installed, and the end of the output shaft of the first motor 26 penetrates and is inserted inside the first rotating frame 12 and is fixedly connected to the threaded rod 24.

[0031] By adopting the above technical solution, the rotation of the end of the output shaft of the first motor 26 drives the threaded rod 24 to rotate, which is used to provide power output.

[0032] On the outer side of the mounting frame 3, a second motor 34 is installed, and the end of the output shaft of the second motor 34 penetrates and is inserted inside the mounting frame 3 and is fixedly connected to the worm 31.

[0033] By adopting the above technical solution, the rotation of the end of the output shaft of the second motor 34 drives the worm 31 to rotate, which is used to provide power output.

[0034] Working principle: First, open the first rotating frame 12, and then, according to the thickness and specifications of the bridge, start the first motor 26, so that the first motor 26 starts to work. The rotation of the end of the output shaft of the first motor 26 drives the threaded rod 24 to rotate, and the rotation of the threaded rod 24 drives the threaded slider 25 to move. The movement of the threaded slider 25 adjusts the telescopic frame 2 to move outside the first rotating frame 12, so as to achieve the telescoping of the vision detector body 23 according to the thickness specifications of the bridge, which can facilitate better detection of the bridge. Then, unfold the second rotating frame 21 so that the second rotating frame 21 is placed at the bottom end of the bridge. Then, move through the electric slider 22 on the second rotating frame 21, thereby driving the vision detector body 23 to move. The movement of the vision detector body 23 can detect the bottom end of the bridge more carefully. When encountering a place that is not easy to observe, at this time, the second motor 34 can be started, so that the second motor 34 starts to work. The rotation of the end of the output shaft of the second motor 34 drives the worm 31 to rotate, the rotation of the worm 31 drives the meshing worm wheel 33 to rotate, the rotation of the worm wheel 33 drives the rotating rod 32 to rotate, and the rotation of the rotating rod 32 drives the vision detector body 23 to rotate, so as to make adjustments and facilitate the observation and detection of the positions that are not easy to observe.
