[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The present utility model provides a flatness detection device for building construction, such as Figure 1-4 As shown, the flatness detection device for building construction comprises: a second guide rail section 2; a first guide rail section 1 and a third guide rail section 3 hinged on the second guide rail section 2 for extending the length of the device, wherein the first guide rail section 1, the second guide rail section 2 and the third guide rail section 3 are all provided with slide grooves; a slider 7 installed in the slide groove, and a shell 8 is fixed on the top of the slider 7; a rotating shaft 9 rotatably installed in the shell 8, and moving wheels 10 are fixed on both sides of the rotating shaft 9; a motor 11 fixed in the shell 8, and meshing bevel gears 12 are installed on the output shaft of the motor 11 and the rotating shaft 9; and a monitoring component arranged on the slider 7 for detecting the flatness of the building.

[0023] In this embodiment, the second guide rail segment 2 serves as the main body of the device, providing a connection basis for other guide rail segments and a basis for the expansion and flexibility of the device. The first guide rail segment 1 and the third guide rail segment 3 are used to extend the overall length of the device. This design enables the device to adapt to detection requirements of different lengths without the need to frequently change the detection area, thereby improving the detection efficiency. The slide groove provides a sliding track for the slider 7. The cooperation between the slider 7 and the slide groove enables the detection component to move flexibly to meet the detection requirements of flatness at different positions. The motor 11 drives the rotating shaft 9 to rotate, thereby driving the moving wheel 10 to rotate, so that the slider 7 slides in the slide groove, realizing the function of automatically adjusting the detection position, reducing the tediousness of manual adjustment, and the combination of the monitoring component and the slider 7 enables the detection to cover a wider area as the slider 7 moves, thereby improving the comprehensiveness and accuracy of the detection.

[0024] In a further preferred embodiment of the utility model, the monitoring component includes a mounting frame 15 detachably mounted on the slider 7; a plurality of springs 16 fixed on the mounting frame 15, and a U-shaped plate 17 is installed at the bottom of the plurality of springs 16; a roller 18 rotatably mounted on the U-shaped plate 17, and the roller 18 can contact the wall or the ground of the building; a grating encoder 19 fixed on the mounting frame 15, and the moving part on the grating encoder 19 is connected to the U-shaped plate 17.

[0025] In this embodiment, the mounting frame 15 is detachably mounted on the slider 7, so that the monitoring component can be easily removed or replaced from the slider 7 as needed. The user can easily replace or adjust the monitoring component according to different detection requirements or damage conditions. The presence of the spring 16 allows the U-shaped plate 17 and the roller 18 to have a certain elastic deformation when contacting the wall or the ground to adapt to the slight undulations of different surfaces. The elastic deformation of the spring 16 can ensure that the roller 18 maintains stable contact with the wall or the ground, while avoiding the violent jumping of the roller 18 on the uneven surface, thereby improving the accuracy of the detection. When the roller 18 rolls on the wall or the ground, the up and down movement of the U-shaped plate 17 will drive the moving part of the grating encoder 19 to move, thereby recording the moving distance and displacement change of the roller 18. The high-precision measurement capability of the grating encoder 19 can accurately record the movement of the roller 18, and then reflect the flatness of the wall or the ground. This measurement method is accurate and reliable and can provide accurate detection results.

[0026] In a further preferred embodiment of the utility model, a plurality of limit rods 5 are rotatably installed on the top and bottom of the second guide rail segment 2, and anti-slip pads 6 are fixed on the side where the plurality of limit rods 5 are close to each other, and the plurality of anti-slip pads 6 can contact the first guide rail segment 1 and the third guide rail segment 3 respectively.

[0027] In this embodiment, the design of the limit rod 5 mainly plays the role of fixing and supporting. When the first guide rail segment 1 and the third guide rail segment 3 are connected to the second guide rail segment 2 by a hinged manner and adjusted to a suitable angle, the limit rod 5 is rotated to make it contact with the first guide rail segment 1 or the third guide rail segment 3, and the friction force is provided by the anti-skid pad 6, so as to prevent the first guide rail segment 1 and the third guide rail segment 3 from undesired displacement or rotation relative to the second guide rail segment 2. This design ensures the stability and accuracy of the device during the detection process. The anti-skid pad 6 is usually made of a material with a high friction coefficient, such as rubber or silicone. The main function of the anti-skid pad 6 is to increase the friction between the limit rod 5 and the first guide rail segment 1 and the third guide rail segment 3, so as to further improve the stability of the device. When the limit rod 5 contacts the first guide rail segment 1 or the third guide rail segment 3, the anti-skid pad 6 can ensure a close fit between them, thereby preventing displacement or rotation caused by vibration or external force during the detection process.

[0028] In a further preferred embodiment of the utility model, two openings are provided at the bottom of the shell 8, and the two movable wheels 10 are fixed with anti-slip sleeves on the outside. The two movable wheels 10 extend to the outside of the shell 8 through the two openings respectively, and the two movable wheels 10 can both contact the third guide rail section 3.

[0029] In this embodiment, through the opening, the moving wheel 10 can freely extend from the inside of the shell 8 to the outside, thereby contacting the third guide rail segment 3. This design enables the slider 7 (installed on the shell 8) to slide smoothly on the third guide rail segment 3. The main function of the anti-slip sleeve is to increase the friction between the moving wheel 10 and the third guide rail segment 3 to prevent slipping or deviation from the track during sliding. This design can ensure the stable sliding of the slider 7 on the third guide rail segment 3 and improve the accuracy and reliability of detection. When the motor 11 drives the rotating shaft 9 to rotate, the moving wheel 10 will rotate accordingly, thereby driving the slider 7 (and the monitoring component fixed on the slider 7) to slide on the third guide rail segment 3. This design enables the monitoring component to be automatically moved along the third guide rail segment 3 without manual intervention, thereby improving the degree of automation and efficiency of detection.

[0030] In a further preferred embodiment of the utility model, mounting plates 13 are fixed on both sides of the slider 7 , fixing bolts 14 are threadedly mounted on the two mounting plates 13 , and the two fixing bolts 14 are threadedly connected to the mounting frame 15 .

[0031] In this embodiment, the mounting plate 13 provides a fixing base for the mounting frame 15. By rotating the fixing bolt 14, it can be tightly connected to the threaded hole on the mounting frame 15, thereby fixing the mounting frame 15. This connection method is simple and reliable, and can quickly and effectively complete the installation and disassembly operations. At the same time, the tightening force of the fixing bolt 14 can also ensure the stability of the mounting frame 15 on the slider 7 to prevent shaking or falling off during the detection process.

[0032] In a further preferred embodiment of the utility model, a plurality of the springs 16 are provided with limit telescopic rods, the plurality of the limit telescopic rods are fixed on the U-shaped plate 17 , and the plurality of the limit telescopic rods are fixedly connected to the mounting frame 15 .

[0033] In this embodiment, the design of the limiting telescopic rod enables the U-shaped plate 17 to maintain a stable moving trajectory under the elastic force of the spring 16, preventing the position of the U-shaped plate 17 from being offset or shaking due to excessive deformation of the spring 16. The limiting telescopic rod can limit the maximum moving distance of the U-shaped plate 17 relative to the mounting frame 15, ensuring that when the roller 18 contacts the wall or the ground, the U-shaped plate 17 will not be damaged or fail due to excessive deformation of the spring 16. By fixing the limiting telescopic rod between the U-shaped plate 17 and the mounting frame 15, the structure of the entire monitoring assembly is more stable, thereby improving the reliability and service life of the device.

[0034] In a further preferred embodiment of the utility model, a plurality of balls are embedded on the top of the mounting frame 15, and the plurality of balls can contact the outer wall of the third guide rail segment 3, and the plurality of balls can also contact the outer walls of the first guide rail segment 1 and the second guide rail segment 2.

[0035] In this embodiment, the ball bearings can contact the outer walls of the third guide rail segment 3, the first guide rail segment 1 and the second guide rail segment 2 when the slider 7 moves along the guide rail. The design of the ball bearings transforms the contact between the mounting frame 15 and the guide rail segments from sliding friction to rolling friction, thereby significantly reducing frictional resistance. This helps the slider 7 to move more smoothly on the guide rail, improves the efficiency and accuracy of detection, protects the integrity of the guide rail, and extends the service life of the guide rail.

[0036] In a further preferred embodiment of the utility model, a support plate 4 is fixed to the side of the first guide rail section 1 and the second guide rail section 2 away from the shell 8, and both support plates 4 can contact the building floor and the building wall.

[0037] In this embodiment, the design of the support plate 4 provides additional support for the guide rail segment, increasing the stability of the entire device. When the device is used on an uneven ground or wall, the support plate 4 can ensure close contact between the device and the building surface, preventing the device from being displaced or tilted due to external force or its own weight. The support plate 4 directly contacts the building ground and wall, reducing direct friction and wear between the guide rail segment and these surfaces. This helps to maintain the integrity of the guide rail segment and extend its service life.

[0038] To sum up, compared with the related art, the present device can reduce the space occupied by the present device during storage by folding the first guide rail segment 1 and the third guide rail segment 3 while ensuring the length of the present device by setting the first guide rail segment 1, the second guide rail segment 2 and the third guide rail segment 3. By setting the motor 11 to drive the rotating shaft 9 to rotate and drive the moving wheel 10 to rotate, the slider 7 can be moved, thereby driving the monitoring component to detect the flatness of the wall and the ground. The slider 7 and the mounting frame 15 are connected by the fixing bolts 14 to facilitate the disassembly and replacement of the monitoring component.
