A movable box is located on the left side of the top of the workbench. A motor is located at the bottom of the inner cavity of the movable box, and a screw is located at the output end of the motor. The top of the screw is movably connected to the movable box via a movable base. A threaded sleeve is threaded onto the surface of the screw, and a sliding sleeve is provided on the surface of the threaded sleeve. In this invention, the pulley is aligned with the wall surface, the coloring head on the right side of the push rod contacts the drawing board, the motor runs, and the motor drives the screw to rotate. The screw drives the threaded sleeve to move up and down, the threaded sleeve drives the sliding sleeve to move, the sliding sleeve drives the push rod to move, and the push rod drives the pulley to move. The pulley moves on the wall, and when the pulley encounters unevenness, it... However, the device lacks a disassembly mechanism for the rollers, making it impossible to replace them when they are severely worn. Severely worn rollers may also exhibit problems such as reduced diameter and uneven surface. If they cannot be replaced, the rollers will become unstable when rolling on the wall, affecting the distance and pressure changes between the detection device and the wall, thus reducing the accuracy of wall flatness detection. Therefore, improvements are needed. Utility Model Content

A sliding hole 15 is provided through the outer wall of the insertion post 11. A round hole 16 is provided on one side of the connecting frame 12.

The pressure sensor 5 and the warning light 4 are electrically connected to the control panel 3.

[0022] In this embodiment, by setting a structure that facilitates the disassembly and replacement of the roller 13, a new roller 13 can be promptly replaced when the roller 13 becomes worn, resulting in a smaller diameter or an uneven surface that affects the detection. This ensures that the roller 13 rolls smoothly on the wall and avoids abnormal changes in the distance and pressure between the detection device and the wall due to roller 13 issues. As a result, the accuracy of wall flatness detection is improved, and the detection results can more accurately reflect the actual flatness of the wall, providing a reliable basis for controlling the quality of the building.

[0023] Example 2: As Figure 1As shown, a vertical frame 22 is fixedly installed on the top of the base plate 1, a first motor 23 is fixedly installed on the top of the vertical frame 22, a lead screw 24 is fixedly installed at the output end of the first motor 23, a sliding block 25 is threadedly connected to the outer wall of the lead screw 24, a rectangular shell 26 is fixedly installed on one side of the sliding block 25, a second motor 27 is fixedly installed at one end of the rectangular shell 26, a lead screw 28 is fixedly installed at the output end of the second motor 27, a sliding block 29 is threadedly connected to the outer wall of the lead screw 28, the sliding block 29 is fixedly connected to the shell 2, the sliding block 25 is slidably connected to the vertical frame 22, and the sliding block 29 is slidably connected to the rectangular shell 26.

[0024] In this embodiment, the first motor 23 drives the lead screw 24 to rotate, causing the sliding block 25 to slide on the frame 22, and the second motor 27 drives the lead screw 28 to rotate, causing the sliding block 29 to slide inside the rectangular shell 26, thereby driving the shell 2 and the roller 13 to move in the vertical and horizontal directions, realizing the function of rapid and comprehensive detection of different positions of the wall, and greatly improving the detection efficiency.

[0025] The working principle of this embodiment is as follows: In use, the detection device is first moved to the position of the wall to be detected by the bottom moving wheel 31. When the detection device approaches the wall, the roller 13 on the connecting frame 12 first contacts the wall. As the device continues to approach the wall, the roller 13 is subjected to the reaction force of the wall, which pushes the slide plate 8 to slide in the housing 2 through the connecting column 9. During the sliding process, the slide plate 8 will squeeze the spring 7. The spring 7 transmits the force to the force plate 6. The pressure sensor 5 on the force plate 6 detects the pressure change in real time. If the wall is uneven, the reaction force of the roller 13 at different positions is different, resulting in different degrees of compression of the spring 7. The pressure value detected by the pressure sensor 5 will also be different. The threshold of the pressure sensor 5 can be set through the control panel 3. When the pressure value exceeds the threshold range, it indicates that the wall is uneven at that position. The control panel 3 controls the warning light 4 to light up to remind the inspection personnel. When vertical movement detection is required, the first motor 23 is started first. The first motor 23 drives the lead screw 24 to rotate. Since the lead screw 24 is threadedly connected to the sliding block 25, and the sliding block 25 is slidably connected to the frame 22, the rotation of the lead screw 24 causes the sliding block 25 to move vertically up and down on the frame 22. During this up-and-down movement, the sliding block 25 drives the rectangular shell 26 and other connected components to move vertically, thus achieving flatness detection at different heights of the wall. When horizontal movement detection is required, the second motor 27 is started first. The second motor 27 drives the lead screw 28 to rotate. Since the lead screw 28 is threadedly connected to the sliding block 29, and the sliding block 29 is slidably connected to the rectangular shell 26, the rotation of the lead screw 28 causes the sliding block 29 to move horizontally within the rectangular shell 26. During this horizontal movement, the sliding block 29 drives the housing 2 and the detection components connected to the housing 2 to move horizontally, thus achieving flatness detection at different horizontal positions of the wall. When roller 13 is severely worn and needs to be disassembled and replaced, first pull the lever 21. The lever 21 drives the sliding column 20 to slide in the round hole 16. During the sliding process, the sliding column 20 will drive the connecting plate 18 to slide inside the slide groove 14. During the sliding process, the connecting plate 18 will squeeze the spring 17. After a certain degree of compression, the limiting post 19 on one side of the connecting plate 18 will be withdrawn from the limiting hole 10. After withdrawal, the insert post 11 can be slid outward along the inside of the connecting post 9 and pulled out. The end of the insert post 11 away from the connecting post 9 is fixedly installed with the connecting frame 12. The roller 13 is rotatably connected inside the connecting frame 12. When the insert post 11 is pulled out, the roller 13 will be disassembled from the connecting post 9 along with the connecting frame 12, thereby realizing the disassembly of the roller 13 and facilitating the subsequent replacement of the new roller 13.

[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
