Description

Technical Field

[0001] This invention belongs to the field of wall sanding technology, and in particular relates to a device for leveling building walls. Background Technology

[0002] After the main structure of newly built residential, commercial, and office buildings is completed, the walls often have problems such as uneven concrete pouring and gaps in the masonry blocks. In order to meet the basic requirements of subsequent wall plastering, tiling, painting and other decorative processes, it is necessary to use a leveling device to pre-treat the wall surface to ensure that the flatness of the base layer meets the standards. For example, a wall grinding device for building construction is disclosed in patent publication number CN114147561A.

[0003] To create a distinctive visual appearance, enhance spatial comfort, and optimize functional layout, some buildings incorporate curved walls. However, when using traditional leveling equipment on these curved walls, the lack of real-time curvature detection tools adapted to large curves means the equipment cannot rely on fixed benchmarks for grinding. Instead, it depends on the operator's experience, which easily leads to problems such as "local curvature being ground flat" or "overall curvature deviating from the design value." This directly disrupts the overall smoothness and aesthetic appeal of the curved wall. Furthermore, grinding tools inevitably wear down over time. If operators do not replace worn tools in time, the reduced cutting force will not effectively remove wall protrusions, and the uneven tool surface may even react against the wall, causing new grinding defects and further affecting the quality of wall leveling.

[0004] To address this issue, a wall leveling device is proposed. Summary of the Invention

[0009] In the aforementioned building wall leveling device, the detection component includes a detection linear module fixedly connected to the inner wall of the grinding frame.

The end of the sliding plate away from the lifting block extends out of the sliding opening and is fixedly connected to a friction plate. An elastic rod is fixedly connected to the lower inner wall of the detection box. A trigger switch is fixedly connected to the upper end of the elastic rod.

A traction seat 13 is fixedly connected to the upper side wall of the track seat 6. The upper end of the traction seat 13 passes through the track frame 51 and is fixedly connected to the lower side wall of the moving plate 1. The track assembly 5 can be spliced ​​according to the curvature of the wall surface, facilitating the grinding of curved walls. The moving end of the track assembly 5 is connected to... A movable plate 1 is connected to the upper side wall of the movable plate 1. An angle motor 2 and a controller 3 are connected to the upper side wall of the movable plate 1. A rotating plate 4 is connected to the output end of the angle motor 2. A grinding assembly 14 is connected to the upper side wall of the rotating plate 4. The grinding assembly 14 includes a lead screw linear module 141 fixedly connected to the upper side wall of the rotating plate 4.

A grinding frame 16 is fixedly connected to the moving end of the transverse electric push rod 15. Rotating shafts 17 are rotatably connected to the upper and lower inner walls of the grinding frame 16. Each end of the rotating plate 4 is connected to the same grinding roller 18 via a connecting flange. The grinding roller 18 is composed of multiple grinding single shafts. Two laser rangefinders 38 are symmetrically fixed to the right side wall of the rotating plate 4. Both laser rangefinders 38 are electrically connected to the controller 3. This component allows the grinding roller 18 to be perpendicular to the tangent of the arc of the wall surface, improving the grinding quality. A grinding motor 19 is fixedly connected to the upper side wall of the grinding frame 16. The output end of the grinding motor 19 passes through the grinding frame 16 and is fixedly connected to the upper rotating shaft 17 via a torque sensor. This allows for grinding of uneven areas of the wall surface. The component also includes: The detection component 20, located inside the grinding component 14, is used to detect the wear degree of the grinding elements inside the grinding component 14. The detection component 20 includes a detection linear module 201 fixedly connected to the inner wall of the grinding frame 16. A small electric push rod 202 is connected to the moving end of the detection linear module 201. The moving end of the small electric push rod 202 is connected to the detection box 21 through a pressure sensor. A lifting block 22 is connected to the upper inner wall of the detection box 21 through a spring. A sliding plate 23 is fixedly connected to the side wall of the lifting block 22 near the grinding roller 18. A sliding plate 23 is provided on the right side wall of the detection box 21 to match the sliding plate 23. The sliding plate 23 extends out of the sliding port at one end away from the lifting block 22 and is fixedly connected to a friction plate 24. An elastic rod 25 is fixedly connected to the lower inner wall of the detection box 21, and a trigger switch 26 is fixedly connected to the upper end of the elastic rod 25. The trigger switch 26 is electrically connected to the controller 3 and can detect the wear degree of the grinding roller 18. A bent rod 35 is fixedly connected to the right side wall of the rotating plate 4, and a pressure sensor 36 is fixedly connected to the right end of the bent rod 35. The detection end of the pressure sensor 36 is connected to a squeezing wheel 37, and the pressure sensor 36 is electrically connected to the controller 3. Through this component, the placement angle of the grinding roller 18 can be further determined. A dust collection component 27 is disposed on the surface of the polishing component 14 and is used to adsorb dust generated during the polishing process. The dust collection component 27 includes a mounting cover 271 fixedly connected to the upper side wall of the lifting plate 142. A dust collection box 272 is fixedly connected to the upper side wall of the mounting cover 271. An air pump 28 is fixedly connected to the upper side wall of the dust collection box 272.

A suction hood 29 is fixedly connected to both the front and rear sides of the polishing frame 16. The suction hood 29 has a hollow structure and multiple dust suction holes are opened on the inner wall of the suction hood 29.

The same telescopic flexible hose 31 is fixedly connected between the dust collection box 272 and the U-shaped tube 30. Through this component, the dust generated during polishing can be collected.

[0021] A vertical plate 32 is fixedly connected to the lower side wall of the grinding frame 16, and a detection electric push rod 33 is fixedly connected to the right side wall of the vertical plate 32. A laser ranging module 34 is fixedly connected to the moving end of the detection electric push rod 33. The laser ranging module 34 is electrically connected to the controller 3 and can automatically detect the position of uneven areas on the wall.

[0022] The operating principle of this invention is explained as follows: During construction, the actual curvature of the wall is first measured, and a matching specification is selected from the prefabricated universal track frame 51. The track assembly 5 is then assembled using bolted fastening plates 52. For special curvatures, a small number of custom-made dedicated track frames 51 can be used in conjunction with the universal model to balance cost and adaptability. The track assembly 5 is then placed at a certain distance along the wall (the operator can...). Figure 7The auxiliary support shown in the drawing ensures that the distance between the track frame 51 and the corresponding contact point on the wall is consistent. Then, the operator places the track seat 6 into the assembled track frame 51. The drive motor 8 on the surface of the track seat 6 will drive the drive gear 9 to rotate. Through the meshing of the drive gear 9 and the drive tooth plate 10, the track seat 6 can be controlled to move along the assembled track frame 51. During the movement of the track base 6, the moving plate 1 is moved along with the traction base 13. The moving plate 1, in turn, moves the rotating plate 4 and the grinding assembly 14 together via the angle motor 2. During the movement of the grinding assembly 14, the controller 3 controls the detection electric push rod 33 to operate. The detection electric push rod 33 moves the laser ranging module 34 towards the wall to a set position. The controller 3 also controls the laser ranging module 34 to operate, emitting a laser beam towards the wall and measuring the laser reflection distance in real time. When there is a protrusion on the wall, the distance between this protrusion and the laser ranging module 34 will be less than the distance to a flat area. The internal system of the controller 3 automatically determines the protrusion position by comparing the distance difference and records it. After detecting a protrusion on the wall, the controller 3 drives the motor 8 to stop, thus positioning the laser ranging module 34 directly below the protrusion. Then, the controller 3 drives the laser rangefinders 38 on both sides of the rotating plate 4 to operate, and by analyzing the electrical signals fed back by the two laser rangefinders 38, controls the angle motor 2 to rotate at an appropriate angle. The angle motor 2 rotates... Plate 4 drives the grinding assembly 14 and the two laser rangefinders 38 to rotate together until the measured distances fed back by the two laser rangefinders 38 are the same. At this time, the grinding assembly 14 will be perpendicular to the tangent of the arc of the wall (since the protrusion on the wall is located above the two laser rangefinders 38, the wall protrusion will not affect the operation of the laser rangefinders 38). When the rotating plate 4 drives the grinding assembly 14 to be perpendicular to the tangent of the arc of the wall, the rotating plate 4 will drive the pressure sensor 36 and the extrusion wheel 37 to contact the wall through the bent rod 35. Since the track assembly 5 and the wall are in contact, the pressure sensor 36 and the extrusion wheel 37 will contact the wall. Holding the set position, when the rotating plate 4 drives the pressure sensor 36 and the extrusion wheel 37 to contact the wall through the bent rod 35, the pressure pressure between the extrusion wheel 37 and the wall will be detected by the pressure sensor 36. When the pressure sensor 36 and the extrusion wheel 37 are perpendicular to the tangent of the arc of the wall, the pressure sensor 36 will detect an extrusion force of 10N. The pressure sensor 36 will feed back a set electrical signal to the controller 3. Through the dual feedback of the pressure sensor 36 and the two laser rangefinders 38, it is further ensured that the grinding component 14 is perpendicular to the tangent of the arc of the wall. Next, the controller 3 drives the grinding roller 18 upward to the set position through the lead screw linear module 141, so that the grinding roller 18 is at the same height as the wall protrusion. Then, the controller 3 controls the horizontal electric push rod 15 and the grinding motor 19 to work simultaneously. The horizontal electric push rod 15 will drive the grinding roller 18 to move closer to the wall protrusion, and the grinding motor 19 will drive the grinding roller 18 to rotate, using the grinding roller 18 to grind the wall protrusion. At the same time, the track assembly 5 will also drive the grinding roller 18 to move back and forth along the wall, expanding the working range of the grinding roller 18. During the operation of the track assembly 5, the controller 3 controls the angle motor 2 to work through the electrical signals fed back by the two laser rangefinders 38 and the pressure sensor 36, ensuring that the grinding roller 18 is always perpendicular to the wall and ensuring the grinding quality. When the grinding roller 18 wears down due to prolonged use, its grinding force decreases. The grinding motor 19 is connected to the grinding roller 18 via a torque sensor. After the grinding roller 18 wears down, the torque sensor detects the decrease in torque. When the controller 3 detects that the torque is consistently below 70%-80% of the reference value, the controller 3 will pause the grinding operation and activate the small electric push rod 202. The small electric push rod 202, via a pressure sensor, moves the detection box 21, causing the friction plate 24 to contact the grinding roller 18. When the controller 3 detects that the pressure between the friction plate 24 and the grinding roller 18 reaches 20N, the controller 3 will stop the small electric push rod 202, maintaining a 20N pressure between the friction plate 24 and the grinding roller 18. Then, the controller 3 activates the detection linear module 201, which, via the small electric push rod 202, moves the detection box 21 downwards. When the detection box 21 moves, the lifting block 22, sliding plate 23 and friction plate 24 move downward together via the spring. As the surface roughness of the abrasive decreases after the grinding roller 18 is worn, the friction between the grinding roller 18 and the friction plate 24 decreases. Under the action of the spring force, the decreased friction can only move the friction plate 24 and the lifting block 22 upward a short distance. At this time, the lifting block 22 will not separate from the trigger switch 26, indicating that the detection section of the grinding roller 18 is severely worn. The trigger switch 26 will continuously transmit an electrical signal to the controller 3, and the controller 3 will record the worn section of the grinding roller 18 (the controller 3 can determine which section of the grinding roller 18 is being detected by detecting the stroke of the linear module 201) and notify the operator through the internal wireless communication module. The operator can then replace the worn section of the grinding roller 18 (the grinding roller 18 is composed of multiple grinding single shafts connected together, and each single shaft can be independently disassembled, making it convenient to replace the corresponding single shaft for the worn local area).
