Description

Technical Field

[0001] This utility model relates to the field of building wall grinding technology, and in particular to a building wall grinding and polishing device. Background Technology

[0002] During the construction process, the building walls are often not flat after pouring. At this time, it is necessary to grind the wall surface to ensure the flatness of the wall surface during subsequent tile installation.

[0003] In existing wall sanding operations, workers typically use sandpaper or handheld sanding equipment. While this method can achieve the required smoothness, it often requires multiple sanding passes, making it difficult to achieve a smooth finish in one go. This significantly reduces construction efficiency and affects the overall project schedule.

[0004] To address the problem that existing sanding equipment struggles to achieve a smooth finish on building walls in a single pass, a sanding device is designed that can maintain constant contact with the wall surface and control the sanding force to overcome this issue. Utility Model Content

[0005] In order to overcome the problem that existing sanding equipment is unable to achieve a smooth finish in one go during the sanding of building walls.

[0006] The technical solution of this utility model is as follows: a building wall grinding and polishing device, including a main support frame and a handle, as well as a secondary support frame, a positioning plate and a motor. The handle is fixedly connected to the upper end of the main support frame, and the secondary support frame is fixedly installed on the upper end of the main support frame. The main support frame is provided with a rectangular opening, and the positioning plate is fixedly installed on the rectangular opening of the main support frame. The motor is slidably arranged on the positioning plate, and a grinding mechanism is provided on the positioning plate. The main support frame is provided with a sliding mechanism.

[0007] Preferably, the sanding mechanism can move laterally on the building wall, and the sanding surface can always be sanded with the same force during the movement. The sanding mechanism can adjust the sanding force and is suitable for sanding different types of wall surfaces. When sanding a wall surface with a large horizontal area, the sliding mechanism can be installed on the building wall so that the horizontal movement trajectory remains flat during the horizontal sanding process and saves the worker's physical strength.

[0008] Preferably, the grinding mechanism includes a slide rod, a connecting plate, a support base, a threaded rod, a rotating handle, a spring, a connecting rod, a rotating disk, and a grinding pad. The slide rod is slidably mounted on the positioning plate. Connecting plates are fixedly connected to both ends of the slide rod. A support base is fixedly connected to the upper end of the upper connecting plate. A threaded rod is threadedly connected to the upper end of the secondary support frame. A rotating handle is fixedly connected to the upper end of the threaded rod. A spring is fitted onto the slide rod. A connecting rod is fixedly connected to the end of the motor's output shaft. A rotating disk is fixedly connected to one end of the connecting rod. The lower end of the rotating disc has a Velcro surface, and the polishing pad has a Velcro hook surface. The rotating disc and the polishing pad are connected by the Velcro surface and the Velcro hook surface. The polishing pad on the rotating disc is in contact with the building wall. At this time, the motor is started, and the motor drives the rotating disc to rotate through the connecting rod. The polishing pad on the rotating disc polishes the building wall. Pulling the handle horizontally makes the main support frame slide on the building wall through the roller, thereby polishing the building wall horizontally. If the polishing force is insufficient, turn the rotating handle so that one end of the threaded rod abuts against the support base.

[0009] Preferably, the upper end of the support base is provided with a groove, and a rubber pad is fixedly connected in the groove. The groove is adapted to one end of the threaded rod. After one end of the threaded rod abuts against the groove of the support base, the vibration amplitude of the motor is reduced during grinding. The rubber pad ensures that there is no gap between the threaded rod and the support base, thus avoiding vibration and noise.

[0010] Preferably, the spring is located between the positioning plate and the lower connecting plate. The spring is used to press down the lower connecting plate and provide downward pressure during grinding to ensure the grinding effect.

[0011] Preferably, the sliding mechanism includes a bottom support frame, a roller, a second sliding rod, and a fixed seat. The bottom support frame is fixedly connected to the lower end of the main support frame, and the roller is rotatably connected to the bottom support frame. The main support frame has holes, and the second sliding rod passes through the holes in the main support frame. The main support frame slides on the second sliding rod. A fixed seat is fixedly connected to one end of the second sliding rod. When performing large-area horizontal grinding, the fixed seat is fixedly installed on the building wall, and another fixed seat is connected to one side of the second sliding rod and fixed to the building wall. In this way, when performing large-area horizontal work, the workers' physical strength is saved, and the grinding path is smooth.

[0012] Preferably, one end of the slide rod two is provided with a threaded connector, and the other end of the slide rod two is provided with a threaded hole. The threaded connector of the slide rod two can be connected to the threaded hole of another slide rod two. Depending on the width of the wall, the threaded hole at one end of the slide rod two can be connected to the threaded connector at one end of another slide rod two, thus making it suitable for installation on building walls of different widths.

[0013] Preferably, the mounting base has holes for the positioning screws to pass through, and the other mounting base has a threaded hole that is threadedly connected to the threaded connector of the slide rod two. After the slide rod two is fixed to the building wall, the other mounting base is connected to the other end of the slide rod two, thus completing the installation of the slide rod two.

[0014] The beneficial effects of this utility model are:

[0015] 1. The sanding mechanism can move laterally on the building wall, and the sanding surface can always be sanded with the same force during the movement. The sanding force can be adjusted and it is suitable for sanding different types of wall surfaces.

[0016] 2. When sanding walls with a large horizontal area, the sliding mechanism can be installed on the building wall to ensure that the horizontal movement trajectory remains flat during the horizontal sanding process, and saves the labor of workers. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please see Figure 1-Figure 5This utility model provides an embodiment of a building wall grinding and polishing device, including a main support frame 1 and a handle 2, as well as a secondary support frame 3, a positioning plate 4, and a motor 7. The handle 2 is fixedly connected to the upper end of the main support frame 1, and the secondary support frame 3 is fixedly installed on the upper end of the main support frame 1. The main support frame 1 has a rectangular opening, and the positioning plate 4 is fixedly installed on the rectangular opening of the main support frame 1. The motor 7 is slidably mounted on the positioning plate 4, and a grinding mechanism is provided on the positioning plate 4. The main support frame 1 has a sliding mechanism. The grinding mechanism can move laterally on the building wall, and during the movement, the grinding surface can always be ground with the same force. The grinding mechanism can adjust the grinding force and is suitable for grinding different types of wall surfaces. When grinding walls with a large horizontal area, the sliding mechanism can be installed on the building wall so that the horizontal movement trajectory remains flat during the horizontal grinding process, and saves the worker's physical strength.

[0025] Please see Figure 1 and Figure 5 In this embodiment, the polishing mechanism includes a slide rod 5, a connecting plate 6, a support base 8, a threaded rod 9, a rotating handle 10, a spring 11, a connecting rod 12, a rotating disk 13, and a polishing pad 14. The slide rod 5 is slidably mounted on the positioning plate 4. The two ends of the slide rod 5 are fixedly connected to the connecting plate 6. The upper end of the connecting plate 6 is fixedly connected to the support base 8. The upper end of the secondary support frame 3 is threadedly connected to the threaded rod 9. The upper end of the threaded rod 9 is fixedly connected to the rotating handle 10. A spring 11 is sleeved on the slide rod 5. The output shaft end of the motor 7 is fixedly connected to the connecting rod 12. One end of the connecting rod 12 is fixedly connected to the rotating disk 13. The lower end of the rotating disk 13 has a Velcro surface. The polishing pad 14 has a Velcro hook surface. The rotating disk 13 and the polishing pad 14 are connected by the Velcro surface and the Velcro hook surface. The upper end of the support base 8 has a groove, and a spring 11 is fixedly connected within the groove. A rubber pad with a groove is fitted to one end of the threaded rod 9. A spring 11 is located between the positioning plate 4 and the lower connecting plate 6. The spring 11 is used to press down the lower connecting plate 6. The grinding pad 14 on the rotating disk 13 is in contact with the building wall. At this time, the motor 7 is started. The motor 7 drives the rotating disk 13 to rotate through the connecting rod 12. The grinding pad 14 on the rotating disk 13 grinds and polishes the building wall. Pulling the handle 2 laterally causes the main support frame 1 to slide on the building wall through the roller 16, thereby grinding the building wall laterally. When the grinding force is insufficient, turn the rotating handle 10 so that one end of the threaded rod 9 abuts against the support base 8. After one end of the threaded rod 9 abuts against the groove of the support base 8, the shaking amplitude of the motor 7 is reduced during grinding. The rubber pad ensures that there is no gap between the threaded rod 9 and the support base 8 to avoid vibration and noise. During grinding, it provides downward pressure to ensure the grinding effect.

[0026] Please see Figures 2-4In this embodiment, the sliding mechanism includes a bottom support frame 15, a roller 16, a second slide rod 17, and a fixed seat 18. The bottom support frame 15 is fixedly connected to the lower end of the main support frame 1, and the roller 16 is rotatably connected to the bottom support frame 15. The main support frame 1 has a hole, and the second slide rod 17 passes through the hole in the main support frame 1, allowing the main support frame 1 to slide on the second slide rod 17. One end of the second slide rod 17 is fixedly connected to the fixed seat 18, and one end of the second slide rod 17 has a threaded connector. The other end of the second slide rod 17 has a threaded hole, which can be connected to the threaded hole of another second slide rod 17. The fixed seat 18 has a hole for a positioning screw to pass through, and the other fixed seat 18 has... The slide rod 17 has a threaded hole that is threadedly connected to the threaded connector of the slide rod 17. When performing large-area horizontal grinding, the fixing seat 18 is fixedly installed on the building wall, and another fixing seat 18 is connected to one side of the slide rod 17 and fixed to the building wall. This saves the labor of workers when performing large-area horizontal work, and the grinding route is smooth. According to the width of the wall, the threaded hole at one end of the slide rod 17 is connected to the threaded connector at one end of the other slide rod 17, so that it can be used for building wall installation of different widths. After the slide rod 17 is fixed to the building wall, the other fixing seat 18 is connected to the other end of the slide rod 17, thus completing the installation of the slide rod 17.

[0027] During use, hold the handle 2 and press the roller 16 against the wall. During this process, the spring 11 presses the connecting plate 6, causing the motor 7 to slide downwards. The grinding pad 14 on the rotating disk 13 then contacts the building wall. At this time, start the motor 7, and the grinding pad 14 on the rotating disk 13 polishes the building wall. Pull the handle 2 horizontally so that the main support frame 1 slides on the building wall via the roller 16, thereby grinding the building wall horizontally. If the grinding force is insufficient, turn the rotating handle 10 to increase the contact pressure between the grinding pad 14 and the building wall, thereby increasing the grinding force. When large-area horizontal grinding is required, fix the fixing seat 18 on the building wall. Then, assemble the slide rod 17 according to the width of the wall. Connect another fixing seat 18 to one side of the slide rod 17 and fix it to the building wall. This saves the worker's physical strength when performing large-area horizontal work, and the grinding path is smooth.

[0028] Through the above steps, the sanding mechanism can move laterally on the building wall, and during the movement, the sanding surface can always be sanded with the same force. The sanding force can be adjusted, and it is suitable for sanding different types of walls. When sanding walls with a large horizontal area, the sliding mechanism can be installed on the building wall, so that the horizontal movement trajectory remains flat during the horizontal sanding process, and saves the worker's physical strength.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
