[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figures 1-4 A composite slab joint crack detection device includes a frame 1. A support frame 2 is bolted to the top of the frame 1. Multiple connecting frames 7 are provided on one side of the support frame 2, and the connecting frames 7 are fixed to the support frame 2 by an adjustment mechanism. Two guide rails 12 are bolted to one side of each of the multiple connecting frames 7. Mounting frames 9 are slidably connected to the outer walls of the two guide rails 12 on multiple sides. A laser line array camera 10 is bolted to one side of the mounting frame 9. A power component is provided on the top of each of the multiple connecting frames 7 to drive the mounting frame 9 to move up and down. In use, the power component drives the mounting frame 9 to move, thereby adjusting the height of the laser line array camera 10 to meet the needs of trusses of different heights, improving the applicability of the device. At the same time, the position of the connecting frames 7 can be changed by adjusting the mechanism to avoid trusses, perform multi-point detection, and improve the detection accuracy of composite slabs.

[0025] In this invention, the adjustment mechanism includes multiple positioning holes 6, which are evenly distributed at the upper and lower ends of one side of the support frame 2. Each positioning hole 6 located at the upper and lower ends of the same row is threaded with a fixing screw, one end of which passes through the connecting frame 7. Rotating the fixing screw moves it out of the positioning hole 6, thereby adjusting the position of the connecting frame 7 on the support frame 2. After adjustment, one end of the fixing screw is inserted through the connecting frame 7 into the positioning hole 6, and then screwed into the positioning hole 6 to install and fix the connecting frame 7. This allows for the detection of different gaps between trusses, enabling the laser line array camera 10 to detect the composite plate at close range, further improving the accuracy of the detection. The accuracy and power assembly include a fixed plate 8, which is bolted to the top of the connecting frame 7. A lead screw 13 is rotatably connected to the bottom of the fixed plate 8, and the bottom of the lead screw 13 is rotatably connected to the connecting frame 7. The lead screw 13 is also threadedly connected to the mounting frame 9. Rotating the lead screw 13 causes the mounting frame 9 to move along the installation direction of the guide rail 12 under the action of the thread, thereby changing the height of the laser linear array camera 10 and improving the detection accuracy. One end of the lead screw 13 passes through the fixed plate 8 and is bolted to a throttle 11. A limiting mechanism is provided on one side of the fixed plate 8 to fix the rotation angle of the throttle 11. Rotating the throttle 11 can drive the lead screw 13 to rotate, and the laser linear array camera 10 can be moved along the mounting direction of the guide rail 12. After the height of the laser line array camera 10 is adjusted, the height of the laser line array camera 10 can be fixed by a limiting mechanism, improving the operational stability of the device. The limiting mechanism includes a sliding hole 15, which is opened through the top of the fixed plate 8. A sliding rod 14 is slidably connected in the sliding hole 15, and the top of the sliding rod 14 contacts the throttle 11. The bottom of the fixed plate 8 is provided with a pulling component that drives the sliding rod 14 to move upward. The pulling component drives the sliding rod 14 to move upward in the sliding hole 15, thereby increasing the friction between the sliding rod 14 and the throttle 11, and thus fixing the position of the throttle 11. The pulling component includes a first magnetic ring 16 and a second magnetic ring 17. The first magnetic ring 16 is adhered to the bottom of the fixed plate 8, and the sliding rod 14 is slidably connected in the sliding hole 15. Rod 14 passes through the first magnetic ring 16, and the second magnetic ring 17 is attached to the bottom end of the outer circumference of the sliding rod 14. The attraction between the first magnetic ring 16 and the second magnetic ring 17 can drive the sliding rod 14 to slide in the sliding hole 15, providing an upward force to the sliding rod 14, so that the sliding rod 14 can always have an upward thrust. Multiple auxiliary rollers 4 are rotatably connected between the inner walls of both sides of the frame 1. Both sides of the frame 1 are fixed with baffles 5 by bolts. The stacked plate is placed on the auxiliary rollers 4, thereby reducing the friction between the stacked plate and the frame 1, making it easier for the stacked plate to move on the frame 1. The bottom four corners of the frame 1 are fixed with feet 3 by bolts, and multiple feet 3 are symmetrically distributed to support the frame 1.

[0026] Working principle: During use, rotate the fixing screw to move it out of the positioning hole 6, thereby adjusting the position of the connecting frame 7 on the support frame 2. After adjustment, insert one end of the fixing screw through the connecting frame 7 into the positioning hole 6 and screw the fixing screw into the positioning hole 6 to install and fix the connecting frame 7. This allows for the detection of different gaps between trusses. Then, rotate the handle 11, which drives the lead screw 13 to rotate. Under the action of the guide rail 12 and the thread, the mounting frame 9 moves along the installation direction of the guide rail 12, thereby changing the height of the laser linear array camera 10. The laser linear array camera 10 can detect the composite plate at close range, thus meeting the needs of trusses of different heights and improving the applicability of the device. The adsorption of the first magnetic ring 16 and the second magnetic ring 17 can drive the slide rod 14 to slide in the sliding hole 15, providing an upward force to the slide rod 14, so that the slide rod 14 can always have an upward thrust, thereby increasing the friction between the slide rod 14 and the handle 11, and thus fixing the position of the handle 11. At the same time, the position of the connecting frame 7 can be changed by adjusting the mechanism, thereby avoiding the truss and detecting multiple points, improving the detection accuracy of the composite plate.

[0027] Finally, it should be noted that those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
