Technical Field
[0001] This utility model relates to the field of wall construction equipment, and in particular to a wall removal device for building wall repair. Background Technology
[0002] Wall removal devices for building wall repair are specialized equipment used in the field of building maintenance. They achieve rapid removal of old coatings on walls through mechanical scraping. In building repair projects, the quality of wall surface treatment directly affects the repair effect and project efficiency. Therefore, safe and efficient scraping equipment is of great significance for improving construction quality.
[0003] However, existing wall removal devices have significant operational safety defects. Traditional equipment uses a fixed working height design, requiring scaffolding for work at heights. This method not only poses a risk of falls from heights but also results in low construction efficiency. Therefore, a wall removal device for building wall repair is proposed to solve the above problems. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wall scraping device for building wall repair, comprising a sleeve and a telescopic cylinder fitted on the upper end of the sleeve, an installation chamber at the front end of the telescopic cylinder, a wall scraping assembly inside the installation chamber, the wall scraping assembly being used to scrape the surface layer of the wall, a transmission chamber fixedly connected to the lower end of the sleeve, and a first motor fixedly installed on the side of the lower end of the transmission chamber, a transmission assembly inside the transmission chamber, the output end of the first motor being connected to the transmission assembly, a lead screw threadedly installed at the lower end of the telescopic cylinder, the lower end of the lead screw being connected to the transmission assembly, the transmission assembly being used to transmit the power of the first motor to the lead screw, and when the lead screw rotates, driving the telescopic cylinder to extend vertically and move up and down in the sleeve, and a connection port fixedly installed at the lower end of the installation chamber; the wall scraping assembly includes a mounting base, a planing roller rotatably connected inside the mounting base, a second driving component at the left end of the mounting base, and the mounting base and the installation chamber being movably connected by a depth adjustment assembly, the depth adjustment assembly being used to drive the wall scraping assembly to move forward or backward.
[0006] By setting up a first motor, which drives the twin lead screws to rotate synchronously through the transmission component, and under the rotational constraint of the sleeve on the telescopic cylinder, the rotational motion is converted into the precise linear displacement of the telescopic cylinder. Through the quick-release component, the installation chamber, the wall scraping component, and the depth adjustment component are raised and lowered as a whole. This allows workers to directly start the first motor to raise the wall scraping component for high-altitude scraping work after completing the lower half of the wall removal work, eliminating the need to use scaffolding for climbing. This achieves the goal of eliminating the risk of falling from height and improving construction efficiency. It solves the problems of existing wall scraping devices for building wall repair, which rely on scaffolding for climbing due to fixed working height, resulting in high risk of falling from height, low construction efficiency, and high overall costs.
[0007] Furthermore, the quick-release assembly includes a sliding platform, two sliding platforms are fixedly connected to the front end of their corresponding telescopic cylinders, and connecting platforms are fixedly installed on the left and right sides of the rear end of the installation compartment. The sliding platforms and connecting platforms are slidably connected, and the upper ends of both the sliding platforms and connecting platforms are provided with fasteners.
[0008] Furthermore, the fastener includes a pin, and slots are provided at the upper ends of the sliding platform and the connecting platform, with the pin slidably connected to the interior of the slot.
[0009] Furthermore, the depth adjustment component includes connecting grooves opened at the left and right ends of the mounting compartment, the mounting base is slidably connected to the interior of the connecting grooves, and a first driving component is provided at the rear end of the mounting base.
[0010] Furthermore, the first driving component includes a screw, which is fixedly connected to the rear end of the mounting base. A threaded tube is rotatably connected to the middle position of the rear end of the mounting chamber, and the screw is threadedly connected to the inside of the threaded tube.
[0011] Furthermore, the transmission assembly includes gears, two gears are rotatably connected to the lower end of the transmission chamber, a transmission belt is fitted on the outer surface of the two gears, the two gears are fixedly connected to the lower end of their corresponding lead screws, and the output end of the first motor is fixedly connected to the right gear, the first motor is used to drive the right gear to rotate.
[0012] Furthermore, the second driving component includes a second motor, which is fixedly connected to the left end of the mounting base. The output end of the second motor is fixedly connected to the planer roller, and the second motor is used to drive the planer roller to rotate.
[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. The first motor drives the double lead screws to rotate synchronously through the transmission assembly, which drives the telescopic cylinder to move linearly under the constraint of the sleeve. The quick-release assembly links the installation chamber, the wall scraping assembly, and the depth adjustment assembly to lift and lower as a whole. This structure replaces manual climbing with mechanical lifting, completely eliminates the risks of working at height, improves the continuity and efficiency of wall scraping construction, reduces equipment movement and position adjustment time, and is safe and convenient to operate. 2.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Please see Figures 1-6This utility model provides an embodiment of a wall removal device for building wall repair, comprising a sleeve 2 and a telescopic cylinder 8 fitted onto the upper end of the sleeve 2. An installation chamber 1 is provided at the front end of the telescopic cylinder 8, and a wall removal assembly is provided inside the installation chamber 1 for removing the surface layer of the wall. A transmission chamber 3 is fixedly connected to the lower end of the sleeve 2, and a first motor 4 is fixedly installed on the side of the lower end of the transmission chamber 3. A transmission assembly is provided inside the transmission chamber 3, and the output end of the first motor 4 is connected to the transmission assembly. A lead screw 7 is threadedly installed at the lower end of the telescopic cylinder 8. The lower end of the rod 7 is connected to the transmission assembly, which transmits the power of the first motor 4 to the lead screw 7. When the lead screw 7 rotates, it drives the telescopic cylinder 8 to extend to the vertical direction of the sleeve 2 and move up and down. The lower end of the installation chamber 1 is fixedly installed with a connection port 19. The wall-scraping assembly includes a mounting base 14, and a planing roller 17 is rotatably connected inside the mounting base 14. A second driving member is provided at the left end of the mounting base 14. The mounting base 14 and the installation chamber 1 are movably connected by a depth adjustment assembly, which is used to drive the wall-scraping assembly to move forward or backward.
[0018] In this embodiment, by setting a first motor 4, the first motor 4 drives the double lead screw 7 to rotate synchronously through the transmission component. Under the rotational constraint of the sleeve 2 on the telescopic cylinder 8, the rotational motion is converted into the precise linear displacement of the telescopic cylinder 8. The quick-release component links the installation chamber 1, the wall scraping component, and the depth adjustment component to lift and lower as a whole. This allows the workers to directly start the first motor 4 to raise the wall scraping component for high-altitude scraping work after completing the removal of the lower half of the wall, without having to use scaffolding to climb to high places. This eliminates the risk of falling from heights and improves construction efficiency.
[0019] Please see Figure 3 In this embodiment, the quick-release assembly includes a sliding platform 9. Two sliding platforms 9 are fixedly connected to the front end of their corresponding telescopic cylinders 8. Connecting platforms 10 are fixedly installed on the left and right sides of the rear end of the installation chamber 1. The sliding platforms 9 and the connecting platforms 10 are slidably connected. The upper ends of the sliding platforms 9 and the connecting platforms 10 are provided with fixing components, including pins 12. The upper ends of the sliding platforms 9 and the connecting platforms 10 are provided with slots 11. The pins 12 are slidably connected to the inside of the slots 11. By setting the connecting platforms 10, the sliding platforms 9 can be inserted into the sliding grooves in the connecting platforms 10 through their own guide rails, thereby quickly completing the connection between the sliding platforms 9 and their connected parts and the connecting platforms 10. By setting the slots 11 and the pins 12, when the sliding platforms 9 are fully inserted into the connecting platforms 10, the slots 11 on them are aligned with the slots 11 of the connecting platforms 10. Then, the pins 12 are inserted into the slots 11 to fix the position of the sliding platforms 9, thereby achieving the purpose of boltless installation and quick maintenance.
[0020] It should be noted that the pin 12 is made of magnet, while the sliding platform 9 and the connecting platform 10 are made of iron. Thus, when the pin 12 is inserted, a stable connection is achieved through magnetic force.
[0021] Please see Figures 4-6 In this embodiment, the depth adjustment component includes connecting grooves 13 at both ends of the mounting chamber 1. The mounting base 14 is slidably connected to the interior of the connecting grooves 13. A first driving component is provided at the rear end of the mounting base 14. The first driving component includes a screw 16, which is fixedly connected to the rear end of the mounting base 14. A threaded tube 15 is rotatably connected to the middle of the rear end of the mounting chamber 1. The screw 16 is threadedly connected to the interior of the threaded tube 15. By providing the threaded tube 15, when the threaded tube 15 is rotated, the mounting base 14 is restricted from rotation through the connecting grooves 13, so that the screw 16 cannot rotate and the rotational motion is converted into a precise linear displacement of the screw 16. When the screw 16 moves, it drives the mounting base 14 and its connected parts to move together, thereby adjusting the distance of the cutting roller 17 protruding from the mounting chamber 1, so as to achieve the purpose of adjusting the cutting depth.
[0022] Please see Figure 2 , Figure 6 In this embodiment, the transmission assembly includes gears 5. Two gears 5 are rotatably connected to the lower end of the transmission chamber 3. A transmission belt 6 is fitted onto the outer surface of the two gears 5. The two gears 5 are fixedly connected to the lower end of their corresponding lead screws 7. The output end of the first motor 4 is fixedly connected to the right gear 5. The first motor 4 is used to drive the right gear 5 to rotate. By setting the first motor 4, the operation of the first motor 4 drives the right gear 5 to rotate. When the right gear 5 rotates, it drives the left gear 5 to rotate through the transmission belt 6. When both gears 5 rotate, they drive the corresponding lead screws 7 to rotate. The corresponding lead screw 7 rotates to transmit power to the two lead screws 7. The second driving component includes a second motor 18, which is fixedly connected to the left end of the mounting base 14. The output end of the second motor 18 is fixedly connected to the planer roller 17. The second motor 18 is used to drive the planer roller 17 to rotate. By setting the second motor 18, the second motor 18 drives the planer roller 17 to rotate when it runs, so that when the planer roller 17 comes into contact with the wall, it scrapes the wall surface with its own planer teeth, thereby achieving the purpose of removing the surface layer of the wall.
[0023] The working principle of the above embodiments is as follows: When the first motor 4 is running, it drives the right gear 5 in the transmission chamber 3 to rotate, which in turn drives the left gear 5 to rotate synchronously through the transmission belt 6, causing the lead screws 7 at both ends to rotate accordingly. Under the rotation constraint of the sleeve 2 on the telescopic cylinder 8, the rotational motion of the lead screw 7 is converted into the vertical lifting and lowering of the telescopic cylinder 8. The telescopic cylinder 8 is connected to the connecting platform 10 on the installation chamber 1 through the sliding platform 9 at the front end, and is quickly fixed by inserting the magnetic pin 12 into the aligned slot 11. When the threaded tube 15 at the rear end of the installation chamber 1 rotates, it drives the screw 16 connected to it to move the mounting base 14 and the planer roller 17 back and forth along the connecting groove 13 to adjust the scraping depth. The second motor 18 directly drives the planer roller 17 to rotate, and scrapes the wall surface through the planer teeth on its surface.
[0024] It should be noted that the control method of this utility model is controlled by a controller. The control circuit of the controller can be implemented by those skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail here.
