Technical Field

[0001] This application relates to the technical field of engineering supervision, and in particular to laser scanners used in engineering supervision. Background Technology

[0002] Currently, construction supervision requires the use of laser scanners to accurately measure and record the structural features of buildings during construction. Traditional 3D laser scanners typically rely on fixed support structures for measurement, requiring manual adjustment to keep the scanner body level, thereby ensuring the accuracy and consistency of the measurement data.

[0003] A related technology, CN212747697U, describes a 3D laser scanner for construction supervision, comprising a mounting plate, multiple legs hinged to the mounting plate, an adjustment plate mounted above the mounting plate, a scanner body mounted on the adjustment plate, and a level bead mounted on the adjustment plate. A connecting rod is fixed at the center of the bottom surface of the adjustment plate, and a hinged ball is fixed at the bottom end of the connecting rod. The bottom end of the connecting rod is ball-hinged to the mounting plate. Multiple adjustment mechanisms are also provided between the mounting plate and the adjustment plate, and these mechanisms are spaced apart circumferentially along the connecting rod. This application facilitates the adjustment of the 3D laser scanner to a horizontal position.

[0004] The laser scanner used in engineering supervision described above can be easily adjusted to a horizontal position via an adjustment mechanism located between the mounting plate and the adjustment plate. However, this design is mainly suitable for straight or flat building structures. When the building surface has a complex arc-shaped structure, the adjustment mechanism cannot ensure that the laser scanner can accurately fit at different angles and positions, thus affecting the accuracy of the measurement results. Utility Model Content

[0005] In order to address the issue that existing laser scanners used for engineering supervision are difficult to adjust precisely at different angles and positions when the building surface has a complex arc-shaped structure, thus affecting the accuracy of the measurement results, due to their inherent design characteristics, the inventors have found that the adjustment mechanism in the prior art cannot ensure that the laser scanner can fit precisely at different angles and positions. Therefore, this application provides a laser scanner for engineering supervision.

[0006] The laser scanner for engineering supervision provided in this application adopts the following technical solution: it includes a laser scanner and an adjustment component for adjusting the laser scanner; The adjustment assembly includes a mounting plate connected to the laser scanner, a lifting assembly for raising and lowering the mounting plate, and a rotating assembly for rotating the mounting plate.

[0007] By employing the above technical solutions, a laser scanner is used for precise measurement of buildings.

A rotating assembly enables the laser scanner to rotate 360 ​​degrees on a horizontal plane, facilitating the measurement of curved structures. Combining these components allows for comprehensive, multi-angle, and precise measurements of curved structures, improving measurement efficiency and accuracy.

The drive motor is fixedly disposed in the inner cavity of the support base, and the output shaft of the drive motor is connected to the driving gear via a spline.

Figure 2 , Figure 3 and Figure 4 The adjustment assembly includes a mounting plate 5 connected to the laser scanner 100, a lifting assembly for raising and lowering the mounting plate 5, and a rotating assembly for rotating the mounting plate 5. In this invention, the laser scanner 100 is used for precise measurement of buildings. The mounting plate 5 is used to fix the laser scanner 100, ensuring its stability and measurement accuracy. The lifting assembly allows the operator to adjust the height of the laser scanner 100 to adapt to the height requirements of different measurement objects. The rotating assembly enables the laser scanner 100 to rotate 360 ​​degrees on the horizontal plane, facilitating the measurement of buildings with curved structures. By combining these components, precise measurements of curved structures from all directions and multiple angles can be achieved, improving measurement efficiency and accuracy. The working principle is as follows: the laser scanner 100 is fixed by the mounting plate 5, then its height is adjusted using the lifting assembly, and then the laser scanner 100 is allowed to rotate freely on the horizontal plane using the rotating assembly, thus enabling flexible measurement of curved structures at different positions and angles.

The mounting base 52 is fixed at the center of the rear end face of the mounting plate 5, providing a stable foundation for the entire lifting assembly. The connecting shaft 6 is connected to the mounting base 52, serving as the support shaft 32 for the lifting movement. The hydraulic cylinder 4 is connected to the connecting shaft 6 and can adjust the height of the mounting plate 5 by extension and retraction. A fixing plate 3 is fixed at the other end of the hydraulic cylinder 4, and the fixing plate 3 is connected to the rotating assembly, allowing the fixing plate 3 to rotate. The laser scanner 100 is fixed by the mounting plate 5, and the extension and retraction end of the hydraulic cylinder 4 is connected to the connecting shaft 6.

The rotating shaft 31 is fixedly connected to the fixed plate 3 at one end and to the support plate 33 at the other end. A rotating shaft 31 sleeve is provided at the connection point between the rotating shaft 31 and the driven gear 82.

The rotating shaft 31 sleeve at the connection point between the rotating shaft 31 and the driven gear 82 ensures the smoothness of the rotation process. The overall working principle is as follows: the drive motor starts, driving the driving gear 81 to rotate. The driving gear 81 meshes with the driven gear 82, causing the driven gear 82 to rotate around its own circumference, which in turn drives the entire device to rotate via the rotating shaft 31 and the fixed plate 3.

The first slide rail 331 on the outer side and the second slide rail 332 on the inner side of the lower end face of the support plate 33 are used to guide the movement of the support plate 33 and prevent it from deviating during rotation. The first and second ring rails 101 and 102 are fixedly mounted on the support base 1 and are circumferentially arranged around the center of the support base 1 to guide the movement of the first and second slide rails 331 and 332, ensuring that the support plate 33 rotates accurately along a predetermined path. The first and second slide grooves 21 and 22 on the protective cover plate 2 are adapted to the rotating shaft 31 and the support shaft 32, respectively, to fix and protect the supported components. The working principle is as follows: through the cooperation of the first slide rail 331 and the second slide rail 332 with the first ring rail 101 and the second ring rail 102, the support plate 33 can rotate accurately and stably along the ring rail on the support base 1 under the protection of the protective cover plate 2, ensuring the guiding accuracy and stability during the rotation process.

This design allows the connecting shaft 6 and the rotating shaft 31 to be smoothly guided along the slide groove during the movement.

[0028] The implementation principle of the laser scanner used in engineering supervision in this application embodiment is as follows: When in use, the drive motor starts, driving the active gear 81 to rotate. The active gear 81 meshes with the driven gear 82, causing the driven gear 82 to rotate around its own outer circumference, and then rotates through the rotating shaft 31 and the fixed plate 3. During this process, through the cooperation of the first slide rail 331 and the second slide rail 332 with the first ring rail 101 and the second ring rail 102, the support plate 33 can rotate accurately and stably along the ring rail on the support base 1 under the protection of the protective cover plate 2, ensuring the guiding accuracy and stability during the rotation process. The laser scanner 100 is fixed by the mounting plate 5. The telescopic end of the hydraulic cylinder 4 is connected to the connecting shaft 6.
