[0033] The installation assembly comprises a limiting column 9 fixedly connected at both ends inside the shell 2, which is used to limit the movement track of the limiting plate 10 and ensure the stability of the clamping plate 13 during installation. The limiting plate 10 is slidably connected to the outer wall of the limiting column 9, and can slide along the limiting column 9 to adjust the fixed state of the clamping plate 13, facilitating the installation and disassembly of the device. The limiting plate 10 is fixedly connected to a connecting rod 11 on one side, which is used to transmit the displacement of the limiting plate 10, so that the clamping plate 13 can smoothly adjust the position. The clamping plate 13 is fixedly connected to the connecting rod 11 at one end, which is used to clamp the bridge support column, so that the detection device is firmly fixed and the detection accuracy is improved. The clamping plate 13 is fixedly connected to an anti-skid strip 14 on one side, which can enhance the friction between the clamping plate 13 and the bridge support column, prevent the device from sliding due to vibration or wind force, and improve the stability of the device. The connecting rod 11 is provided with a reset assembly on the outer wall, which can provide a reset force to ensure that the clamping plate 13 can quickly reset after installation, increase the use convenience of the device, and the driving assembly comprises a motor 6 fixedly connected to one side of the support rod 1 on the outer wall, which provides driving force to ensure that the detection head 3 can move smoothly along the guide rail 4, and improve the automation degree of the detection process. The motor 6 is fixedly connected to a pulley 7 at the output end, which can transmit the power of the motor 6 to the belt 8 to stably drive the sliding block 5. The pulley 7 is provided with a belt 8 on the outer wall, which is used to connect the pulley 7 and the sliding block 5 to realize the synchronous movement of the sliding block 5 and improve the transmission stability of the detection device. The sliding block 5 is fixedly connected to the outer wall of the belt 8 on one side, and slides smoothly along the guide rail 4 driven by the belt 8, thereby driving the detection head 3 to move uniformly and improving the accuracy of crack detection. The reset assembly comprises a first spring 12 sleeved on the outer wall of the connecting rod 11, which is used to provide a reset force to ensure that the clamping plate 13 can be stably reset after installation is completed, and improve the reliability of the device. One end of the first spring 12 is fixedly connected to one side of the limiting plate 10, and the other end is fixedly connected inside the shell 2, which can effectively control the resetting of the clamping plate 13 during spring contraction and release, improve the installation convenience and stability of the device.
[0034] Specifically, when it is necessary to firmly fix the support rod 1 to the bridge support column, first, the clamping plate 13 is slowly pulled out from the inside of the shell 2 through the connecting rod 11 and is accurately placed at the position of the outer wall of the support column, so that the fitting surface of the clamping plate 13 is fully aligned with the outer wall of the support column. Then, the clamping plate 13 is precisely limited through the cooperation of the connecting rod 11 and the limiting plate 10, so as to ensure the stability of clamping. The limiting plate 10 is controlled and limited in the shell 2 through the limiting column 9, so that the clamping process is uniformly stressed and clamping deviation is avoided. When the clamping plate 13 is in the in-place state, the clamping plate 13 is loosened, so that it is quickly rebounded to the initial fitting state through the guiding action of the limiting plate 10 under the elastic resetting action of the first spring 12 and is tightly attached to the outer wall of the support column, so as to realize firm clamping. In addition, the anti-skid strip 14 is arranged between the clamping plate 13 and the support column, and the surface texture of the anti-skid strip 14 can effectively increase the friction force, so as to further improve the stability of clamping and prevent the clamping plate 13 from sliding due to vibration or external force in the long-term use process. After the device is fixed stably, the motor 6 is started, the output end of the motor 6 starts to drive the belt pulley 7 to rotate, and the belt 8 is driven, so that the sliding block 5 smoothly slides along the outer wall of the guide rail 4, so as to ensure that the detection head 3 can move uniformly and at a constant speed according to the preset path, so as to realize accurate detection of the bridge structure. In the whole process, the sliding block 5 moves stably under the guidance of the guide rail 4, so as to avoid affecting the detection accuracy due to shaking or uneven movement.
[0035] With reference to Figure 4The top of the support rod 1 is fixedly connected with a fixed plate one 15, which plays a role in stabilizing support and provides a fixed reference for angle adjustment of the detection head 3. The fixed plate one 15 is internally provided with a tooth groove 17, which is used for cooperation with a tooth block 20 to realize the functions of angle adjustment and locking of the detection head 3, so as to ensure that the detection head 3 can be stably fixed after adjustment and avoid deviation due to vibration or external force. The fixed plate one 15 is rotatably connected with a rotating shaft 16 internally, which plays a role in rotating support and enables the detection head 3 to be angle-adjusted around the rotating shaft 16 to adapt to different bridge crack detection requirements and improve the applicability of the device. The rotating shaft 16 is internally provided with a limiting groove 18, which is used for providing a sliding channel for a limiting block 21 to ensure that the fixed plate two 19 can be accurately limited along the limiting groove 18 when the angle of the detection head 3 is adjusted, preventing deviation. The rotating shaft 16 is fixedly connected at the top with the bottom of the detection head 3, and this connection of the rotating shaft 16 ensures that the detection head 3 can be rotationally adjusted with the rotating shaft 16, so that the detection head 3 can be adjusted to a suitable detection angle to improve detection accuracy. The rotating shaft 16 is slidably connected with a fixed plate two 19 on the outer wall, so that the fixed plate two 19 can slide along the rotating shaft 16 to play a role in auxiliary limiting and locking when the angle of the detection head 3 is adjusted, ensuring the stability after angle adjustment. The fixed plate two 19 is fixedly connected with the limiting block 21 internally, and the limiting block 21 functions to limit the sliding range of the fixed plate two 19, so that it can be accurately positioned when sliding in the limiting groove 18, thereby ensuring that the tooth block 20 can be accurately aligned with the tooth groove 17 for locking. The limiting block 21 is slidably connected inside the limiting groove 18, and this sliding connection of the limiting block 21 enables the fixed plate two 19 to be appropriately moved along the limiting groove 18 in an unlocked state to facilitate angle adjustment of the detection head 3 and improve the flexibility of adjustment. The fixed plate two 19 is fixedly connected at the bottom with the tooth block 20, which is embedded with the tooth groove 17, and the tooth block 20 is embedded in the tooth groove 17 after reset to realize angle locking of the detection head 3, prevent deviation of the detection head 3 during detection, and ensure the stability and reliability of detection data. The rotating shaft 16 is sleeved with a second spring 22 on the outer wall, which provides elastic reset force to enable the fixed plate two 19 to be automatically reset after unlocking, improving the convenience of angle adjustment. One end of the second spring 22 is fixedly connected with the bottom of the detection head 3, which ensures that the reset force of the spring can effectively act on the detection head 3, so that it can be quickly returned and kept stable after adjustment. The other end of the second spring 22 is fixedly connected with the top of the fixed plate two 19, which ensures that the fixed plate two 19 can be uniformly stressed during adjustment, so that the tooth block 20 can be stably embedded with the tooth groove 17 to improve the reliability and service life of the detection device.
[0036] Specifically, when the angle of the detection head 3 needs to be adjusted accurately, first, the second fixed plate 19 is slowly lifted by hand or an auxiliary device, so that it slides along the limiting groove 18 under the guidance of the limiting block 21 and is ensured to be in a stable limiting state. During the lifting process, the tooth block 20 at the bottom of the second fixed plate 19 gradually separates from the tooth groove 17, so that the angle adjustment function of the detection head 3 is unlocked, avoiding unnecessary resistance or constraints during adjustment. In the unlocked state, the operator can adjust the rotation of the detection head 3 according to the actual detection needs. At this time, the detection head 3 rotates stably inside the first fixed plate 15 through the rotating shaft 16, so that it can be accurately aligned for different detection positions or angle requirements, ensuring the universality of the detection range and the accuracy of the detection data. When the detection head 3 is adjusted to the required angle position, the second fixed plate 19 is loosened, and it is quickly reset to the initial locked state under the elastic force of the second spring 22. During the resetting process, the tooth block 20 of the second fixed plate 19 gradually re-engages with the tooth groove 17 to form a firm locking structure, preventing the detection head 3 from being angularly offset due to external forces during detection, ensuring the stability and continuity of the detection work.
[0037] Working principle: when using the municipal road and bridge crack detection device, first fix the support rod 1 to the bridge support column, then pull out the clamping plate 13 from the shell 2 through the connecting rod 11, and then place it on the outer wall of the support column. The clamping plate 13 is limited by the limiting plate 10 through the connecting rod 11, and the limiting plate 10 is limited in the shell 2 through the limiting column 9. After positioning, loosen the clamping plate 13 to make it reset through the tension of the first spring 12 through the limiting plate 10 to fit on the outer wall of the support column. The clamping plate 13 and the support column are fitted and anti-skid by the anti-skid strip 14. Then the motor 6 output end drives the pulley 7 to rotate, the pulley 7 drives the sliding block 5 to slide on the outer wall of the guide rail 4 through the belt 8, and then drives the detection head 3 to move uniformly for detection, achieving the effect of easy installation on the bridge column and stable movement detection;
[0038] When the angle of the detection head 3 needs to be adjusted, first fix the second fixed plate 19 by the limiting block 21 in the limiting groove 18, make the tooth block 20 at the bottom of the second fixed plate 19 separate from the tooth groove 17, then rotate the detection head 3 to adjust the angle of the detection head 3 by rotating the shaft 16 in the first fixed plate 15. After positioning, loosen the second fixed plate 19 to reset it through the tension of the second spring 22 to support the second fixed plate 19, make the tooth block 20 at the bottom of the second fixed plate 19 and the tooth groove 17 embedded to lock, achieve the effect of easy adjustment of the angle of the detection head.
[0039] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
