[0026] An auxiliary positioning structure for installing an asphalt pavement fiber optic sensor includes a movable base 1, a control key 3 at the upper front of the movable base 1, two mounting screws 2 threadedly connected to the left end of the movable base 1, an auxiliary installation structure 4 snapped onto the upper end of the movable base 1, and an adjustable fiber optic sensor structure 5 fixedly connected to the upper right end of the auxiliary installation structure 4.

[0027] In this embodiment, the auxiliary installation structure 4 includes an installation frame 41. A limiting groove 42 is provided on the left side of the inner plate wall of the installation frame 41. Long clamping plates 43 are fixedly connected to the front and rear left ends of the installation frame 41. The left ends of the two long clamping plates 43 are provided with through screw holes 44. The upper ends of the two long clamping plates 43 are fixedly connected to reinforcing tripods 45. The right ends of the two reinforcing tripods 45 are fixedly connected to the installation frame 41. The installation frame 41 is engaged with the upper end of the movable base 1 by the two long clamping plates 43. The two long clamping plates 43 are detachably connected to the movable base 1 by two screw holes 44 and two mounting screws 2 respectively. The installation frame 41 is located on the right side of the movable base 1.

[0028] The above solution involves directly connecting the long card plate 43 to the upper end of the movable base 1, and then quickly fixing it with the mounting screws 2 through the screw holes 44. This eliminates complex assembly steps, adapts to the needs of rapid road construction, and reinforces the tripod 45 to enhance the connection stability between the long card plate 43 and the mounting frame 41, ensuring structural stability during construction. The detachable connection design facilitates quick disassembly and relocation. The fixed position of the mounting frame 41 provides a foundation for subsequent adjustments, and the limiting groove 42 guides the adjustment structure, reducing operational obstacles. Overall, the installation process is simplified, construction efficiency is improved, and the problem of complex installation steps is solved.

[0029] In this embodiment, the adjustable fiber optic sensor structure 5 includes a driver 51. The output end of the driver 51 passes through the upper middle part of the mounting frame 41 and is fixedly connected to a threaded rod 52. The lower end of the threaded rod 52 is movably connected to the mounting frame 41 via a bearing. A connecting frame 53 is movably connected to the lower part of the outer surface of the threaded rod 52. A limit block 54 is fixedly connected to the lower left side of the connecting frame 53. An auxiliary frame 55 is fixedly connected to the lower end of the connecting frame 53. A rectangular opening 56 is provided on the lower side of the inner plate wall of the auxiliary frame 55. Arc-shaped fixing blocks 57 are fixedly connected to the lower front and lower rear parts of the inner plate wall of the auxiliary frame 55. Slots 58 are provided on the upper left and upper right parts of the two arc-shaped fixing blocks 57. The fiber optic sensor is inserted into the upper end of the two arc-shaped fixing blocks 57. The lower center of the fiber optic sensor body 59 is located within a rectangular opening 56. A snap-fit ​​assembly 60 is inserted above each of the two arc-shaped fixing blocks 57. The connecting frame 53 is slidably connected to the limiting groove 42 via a limiting block 54. The two arc-shaped fixing blocks 57 are arranged in a front-to-back mirror image. The snap-fit ​​assembly 60 includes an arc-shaped snap-fit ​​block 61. Insert blocks 62 are fixedly connected to the left and right rear ends of the arc-shaped snap-fit ​​block 61. Small snap-fit ​​plates 63 are fixedly connected to the rear ends of the two insert blocks 62 that are far apart from each other. The two snap-fit ​​assemblies 60 are arranged in a front-to-back mirror image. The arc-shaped snap-fit ​​block 61 is inserted into the arc-shaped fixing block 57 via two insert blocks 62 and two slots 58. The two small snap-fit ​​plates 63 are snapped into the arc-shaped fixing block 57 together. The lower inner wall of the arc-shaped snap-fit ​​block 61 is snapped into the fiber optic sensor body 59.

[0030] The above solution involves driving the threaded rod 52 to rotate via the driver 51, allowing the connecting frame 53 to slide precisely along the limiting groove 42 with the aid of the limiting block 54. This enables fine-tuning of the height of the fiber optic sensor body 59, replacing manual adjustment and improving accuracy. The fiber optic sensor body 59 is placed on the arc-shaped fixing block 57, and is reinforced by the arc-shaped locking block 61, the insert block 62, and the locking groove 58, along with the small locking plate 63, to ensure that it does not shift during compaction. The rectangular opening 56 ensures that the sensor monitoring end directly contacts the road surface, and the auxiliary frame 55 provides protection. Overall, precise positioning control is achieved, avoiding data distortion and solving the problem of insufficient positioning accuracy.

[0031] It should be noted that this utility model is an auxiliary positioning structure for installing fiber optic sensors on asphalt pavement. In use, firstly, the entire structure is moved flexibly by the movable base 1. The device is started by pressing the control key 3. In the auxiliary installation structure 4, the mounting frame 41 is connected to the movable base 1 by the long clamping plate 43, and then fixed by the mounting screws 2 through the screw holes 44. The reinforced tripod 45 enhances the connection stability and enables rapid assembly. When adjusting the fiber optic sensor structure 5, the driver 51 drives the threaded rod 52 to rotate, and the connecting frame 53 slides along the limiting groove 42 through the limiting block 54, driving the auxiliary frame 55 to rise and fall precisely. The fiber optic sensor body 59 is placed on the arc-shaped fixing block 57, and the arc-shaped clamping block 61 is inserted into the clamping groove 58 through the insert block 62. The small clamping plate 63 clamps and fixes it. The rectangular opening 56 ensures that the sensor monitoring end contacts the road surface. The whole structure is adjusted mechanically to replace manual labor, achieving precise positioning and stable fixation. Thus, all components work together, simplifying the installation process, improving positioning accuracy, ensuring stable sensor operation, and effectively solving the efficiency and accuracy problems of traditional installation.
