If not detected in time, these cracks will gradually expand over time, affecting the structural strength.

[0003] In existing technologies, some crack detection devices have poor flexibility and adaptability in complex engineering environments. Adjustments are complicated to make according to different detection scenarios and crack locations, resulting in low detection efficiency. Utility Model Content

[0018] Please see Figure 1-5 This utility model provides a technical solution: a crack identification device with protective function, including a movable base 1, an adjustment plate 2 and a detection device 3.

[0019] The specific settings and functions of the adjustment plate 2 and the detection device 3 will be explained in detail below.

[0020] In this embodiment: a servo motor 11 is installed inside the movable base 1, and a drive mechanism 12 is installed on the top of the movable base 1. The drive mechanism 12 is fixedly connected to the output end of the servo motor 11, and the bottom of the adjustment plate 2 is fixedly connected to the top of the drive mechanism 12.

[0021] The detection device 3 includes a support frame 31, which is rotatably connected to the adjustment plate 2. A first motor 35 is provided on the top of the support frame 31. A moving mechanism 32 is fixedly connected to the output end of the first motor 35. The detection and identification device body 33 is threadedly connected to the outer surface of the moving mechanism 32. A shock-absorbing column 34 is fixedly connected to the top of the outer surface of the support frame 31.

[0022] The effects achieved by the above components are as follows: the moving base 1 provides the foundation for the overall movement of the device; the servo motor 11 provides power to the drive mechanism 12, driving the adjustment plate 2 to rotate, thereby adjusting the horizontal angle of the detection device 3; in the detection device 3, the support frame 31 provides installation support for each component; the first motor 35 drives the moving mechanism 32 to move the detection and identification device body 33 up and down, realizing crack detection at different heights; and the shock-absorbing column 34 provides protection and shock absorption for the detection and identification device body 33.

[0023] Specifically, the drive mechanism 12 includes a drive wheel 121 fixedly connected to the output end of the servo motor 11. The drive wheel 121 is located on the top of the movable seat 1. A gear disk 122 meshes with the outer surface of the drive wheel 121. The gear disk 122 is rotatably connected to the top of the movable seat 1.

[0024] The effect achieved by the above components is as follows: after the servo motor 11 is started, the output end drives the drive wheel 121 to rotate. Since the drive wheel 121 meshes with the gear disk 122, the gear disk 122 rotates with the drive wheel 121, thereby realizing the 360° horizontal rotation of the adjustment disk 2, meeting the detection requirements of the detection device 3 in different horizontal directions, and improving the flexibility of the device.

[0025] Specifically, the adjusting disc 2 is fixedly connected to the top of the gear disc 122, and the gear disc 122 is internally connected to a rotating shaft 21, with rotating discs 22 threadedly connected to both ends of the rotating shaft 21.

[0026] The effects achieved by the above components are as follows: the adjusting disk 2 rotates synchronously with the gear disk 122, providing a stable mounting platform for the detection device 3; when the rotating shaft 21 is rotated, since the threads at both ends of the rotating shaft 21 are opposite, the two rotating disks 22 will move towards or away from each other along the rotating shaft 21, which can change the horizontal or vertical detection position of the detection device 3. The position of the rotating disk 22 can be adjusted according to the detection scenario, which on the one hand enhances the connection stability between the adjusting disk 2 and the moving seat 1, and on the other hand can adapt to different detection environments and avoid the device shaking from affecting the detection accuracy.

[0027] Specifically, the outer surface of the support frame 31 is provided with a connecting groove, and the moving mechanism 32 is disposed in the connecting groove. The moving mechanism 32 includes a lead screw 321 fixedly connected to the output end of the first motor 35. The end of the lead screw 321 away from the first motor 35 is rotatably connected to the inner bottom of the connecting groove. The outer surface of the lead screw 321 is threadedly connected to a movable seat 322, and the detection and identification device body 33 is fixedly connected to the outer surface of the movable seat 322.

[0028] The effect achieved by the above components is as follows: the first motor 35 drives the lead screw 321 to rotate in the connecting groove. Since the movable seat 322 is threadedly connected to the lead screw 321 and is limited by the connecting groove, the movable seat 322 will move up and down along the lead screw 321, thereby driving the detection and identification device body 33 to move synchronously, realizing the detection of cracks at different heights. There is no need to manually adjust the height of the device, thus improving the detection efficiency.

[0029] Specifically, the shock-absorbing columns 34 are symmetrically distributed on the outer surface of the support frame 31. The shock-absorbing columns 34 include telescopic rods 341 fixedly connected to the side of the support frame 31. A shock-absorbing spring 342 is fixedly connected to the outer surface of the telescopic rod 341. A support pad 343 is fixedly connected to the end of the telescopic rod 341 away from the support frame 31.

[0030] The effects achieved by the above components are as follows: when the device is subjected to collision or vibration during movement or detection, the shock-absorbing spring 342 absorbs the impact force through elastic deformation, and the telescopic rod 341 extends and retracts synchronously to match the deformation of the spring, reducing the impact of vibration on the detection and identification device body 33 and protecting its internal precision components such as cameras and sensors; the support pad 343 is made of rubber, which increases the friction with the contact surface, improves the stability of the device when detecting on an inclined surface, and further buffers the collision force, enhancing the protective effect.

[0031] Specifically, the bottom of the movable base 1 is fixedly connected to the movable wheels 4, and there are four sets of movable wheels 4, which are respectively fixedly connected to the four corners of the bottom of the movable base 1.

[0032] The effect achieved by the above components is as follows: four sets of moving wheels 4 are symmetrically distributed at the bottom of the moving base 1, so that the device is evenly stressed. This makes it easy for operators to push the device to move freely within the testing site. The testing position can be quickly switched without the need for handling. It is especially suitable for large-scale testing scenarios such as large buildings and bridges, reducing labor costs.

[0033] Specifically, a retaining rod 5 is fixedly connected to the top edge of the movable seat 1, and there are two sets of retaining rods 5 symmetrically distributed on the top of the movable seat 1.

[0034] The effect achieved by the above components is that the retaining rod 5 can prevent operators from accidentally touching the rotating gear disk 122, thereby improving the safety of the device.

[0035] Working principle: In use, the device is pushed to the area to be tested by the moving wheels 4, and the surrounding rod 5 provides initial protection for the top part of the moving base 1. The servo motor 11 is started, and its output end drives the drive wheel 121 to rotate. The gear disk 122 rotates with the drive wheel 121, and the adjusting disk 2 rotates synchronously to adjust the horizontal direction of the detection device 3. The rotating shaft 21 is rotated to adjust the position of the rotating disk 22 to stabilize the adjusting disk 2.

[0036] Based on the crack height, the first motor 35 is started, driving the lead screw 321 to rotate. The movable seat 322 moves the detection and identification device body 33 up and down along the connecting groove until it is aligned with the crack position. During the detection process, if the device is subjected to vibration or collision, the telescopic rod 341 of the shock-absorbing column 34 and the shock-absorbing spring 342 buffer the impact force, and the support pad 343 enhances stability, protecting the detection and identification device body 33. After the detection is completed, the motor is turned off, and the device can be pushed to the next detection point.
