Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a wall scraping device for renovating old walls. Background Technology

[0002] In the field of building renovation, old wall renovation is a common and important task. With the improvement of people's living standards and the increasing demands for aesthetics and safety in their living environments, the demand for old wall renovation is growing daily. Old wall renovation not only improves the appearance of buildings but also enhances the performance and durability of the walls, making it significant for the renovation and maintenance of old buildings. It involves multiple stages, with wall removal being a crucial initial step that directly affects the quality and effect of subsequent renovation work.

[0003] When renovating old walls, it's necessary to remove the original surface materials such as putty, paint, and coatings. Traditionally, wall scraping involves workers painstakingly removing the old plaster bit by bit with a scraper. This process is inefficient, costly, produces poor quality, and is physically demanding. Furthermore, the dust generated during scraping is easily inhaled by workers, causing health problems. Another option is to use mechanical devices for wall removal. Current wall scraping machines on the market are motor-driven and require handheld operation, keeping the scraper close to the wall. However, handheld scrapers vibrate during use, causing discomfort for workers. Additionally, the weight of these machines makes them inconvenient for prolonged handling.

[0004] Existing methods for removing plaster during old wall renovation have significant drawbacks. Manual plaster removal is not only inefficient but also struggles to ensure a uniform and smooth wall surface, often resulting in plaster residue. While simple electric scrapers improve efficiency to some extent, they lack sanding and cleaning capabilities, failing to meet the overall wall treatment requirements of old wall renovation and potentially impacting subsequent finishing processes.

[0035] The following is in conjunction with the appendix Figures 1-7 This application will be described in further detail.

[0036] This application discloses a wall scraping device for renovating old walls.

[0037] Reference Figure 1 and Figure 2 As shown, a wall scraping device for old wall renovation includes a mounting basket 1, a mounting bracket 2, a wall scraping mechanism 3, and a sliding mechanism 4. The mounting bracket 2 is arranged on the mounting basket 1, the wall scraping mechanism 3 is arranged on the mounting bracket 2 for scraping the wall plaster, and the sliding mechanism 4 drives the wall scraping mechanism 3 to slide, so as to flexibly adjust the wall scraping position and improve the wall scraping efficiency. The sliding mechanism 4 can drive the wall scraping mechanism 3 to move in different directions, and can cover a larger wall area.

[0038] Reference Figure 2As shown, the sliding mechanism 4 includes a longitudinal sliding component 41 and a transverse sliding component 42. The longitudinal sliding component 41 drives the wall scraping mechanism 3 to slide longitudinally, and the transverse sliding component 42 drives the wall scraping mechanism 3 to slide laterally.

[0039] The longitudinal sliding assembly 41 includes a first movable mounting frame 411 arranged on the side of the mounting basket 1, a vertical lead screw 412 arranged within the first movable mounting frame 411, and a first lead screw motor 413 that drives the vertical lead screw 412 and is arranged on the first movable mounting frame 411. The first movable mounting frame 411 is a frame structure with good strength and stability, ensuring the stability of the first movable mounting frame 411 on the mounting basket 1. There are two first movable mounting frames 411, and each has a sliding rod arranged inside.

[0040] Reference Figure 2 As shown, the lateral sliding assembly 42 includes a second movable mounting bracket 421 arranged on the vertical lead screw 412, a lateral lead screw 422 mounted within the second movable mounting bracket 421, a second lead screw motor 423 driving the lateral lead screw 422, and a second fixing block 424 arranged on the second movable mounting bracket 421 and adapted to the vertical lead screw 412. The second fixing block 424 adopts a guide rail slider structure, with an internal thread inside the guide rail slider that is adapted to the external thread of the vertical lead screw 412, allowing it to slide smoothly on the vertical lead screw 412. The lateral lead screw 422 has a similar structure to the vertical lead screw 412, both achieving movement through threaded transmission. The first lead screw motor 413 is similar to the second lead screw motor 423, both being stepper motors capable of precisely controlling the rotation speed of the lead screw. The second fixing block 424 is fixedly connected to the second movable mounting bracket 421, thereby enabling the second movable mounting bracket 421 to move stably up and down on the vertical lead screw 412. When the first lead screw motor 413 starts, it drives the vertical lead screw 412 to rotate, realizing the lifting and lowering movement of the wall scraping mechanism 3; when the second lead screw motor 423 starts, it drives the horizontal lead screw 422 to rotate, causing the wall scraping mechanism 3 to move in the horizontal direction.

[0041] Reference Figure 2 and Figure 3 As shown, the combination of the longitudinal sliding component 41 and the transverse sliding component 42 enables the wall scraping mechanism 3 to move flexibly in both horizontal and longitudinal directions. Through the coordinated control of the first lead screw motor 413 and the second lead screw motor 423, the wall scraping mechanism 3 can move on the wall surface according to a predetermined trajectory, thereby improving the efficiency and coverage of wall scraping.

[0042] Reference Figure 3As shown, the wall scraping mechanism 3 includes a wall scraping platform 31 arranged on the sliding mechanism 4, a frame 32 arranged on the wall scraping platform 31, a first rotating assembly 33 arranged inside the frame 32 for scraping the wall surface, a first grinding assembly 34 arranged on both sides of the first rotating assembly 33 for grinding the wall surface after scraping, and a first cleaning assembly 35 for cleaning the wall surface to be scraped. The first rotating assembly 33, the first grinding assembly 34, and the first cleaning assembly 35 are synchronously driven by a drive chain assembly 36.

[0043] The wall-scraping platform 31 serves as the support for the entire wall-scraping mechanism 3, providing a stable installation foundation for each component. Furthermore, a sliding block is arranged on the back side of the wall-scraping platform 31. The sliding block is mounted on the transverse lead screw 422 and is threadedly connected to the transverse lead screw 422, thereby enabling the sliding block to slide on the transverse lead screw 422 and thus allowing the entire wall-scraping platform 31 to slide.

[0044] Reference Figure 3 As shown, the first rotating assembly 33 includes a cutting tool 331 and a rotating drive assembly 332 for driving the cutting tool 331 to rotate. The cutting tool 331 is arranged inside the frame 32 and scrapes the wall surface. The cutting tool 331 is a spiral cutting tool, which can better peel off the wall surface during rotation. The rotating drive assembly 332 includes a first drive sprocket 3321 arranged on the side of the cutting tool 331 and a drive motor 3322 arranged on the cutting tool 331 away from the first drive sprocket 3321. The drive motor 3322 can provide power for the rotation of the cutting tool 331. When the drive motor 3322 starts, it drives the cutting tool 331 to rotate inside the frame 32. The first drive sprocket 3321 is coaxially connected to the cutting tool 331 and also rotates with the cutting tool 331, thereby providing power for subsequent synchronous transmission.

[0045] Reference Figure 3 and Figure 4As shown, the first grinding assembly 34 is provided with a first grinding cavity 341, which is arranged inside the frame 32. The first grinding cavity 341 contains a sanding component 342 and a first sanding rotating component 343. The sanding component 342 can be attached to the wall surface after scraping and sand the wall surface, smoothing out the uneven wall surface for subsequent repairs. The sanding component 342 includes a sanding disc 3421 arranged inside the grinding cavity, several connecting posts 3422 arranged on the back side of the sanding disc 3421, a back plate 3423 arranged on the end of the connecting posts 3422, and an elastic spring 3424 arranged circumferentially on the connecting posts 3422. The sanding disc 3421 is circular, and sandpaper is installed on its surface for sanding the wall surface. The connecting column 3422 is cylindrical and serves to connect the sanding disc 3421 and the back plate 3423. An elastic spring 3424 is arranged circumferentially on the connecting column 3422, allowing the sanding disc 3421 to better conform to the wall surface and adapt to unevenness. A first sanding rotating component 343 provides rotation for the sanding component 342. The first sanding rotating component 343 has a rotating disk 3431, on which a first rotating gear 3432, coaxial with the rotating disk 3431, is arranged. A first grinding transmission component 344 is meshed on the side of the first rotating gear 3432. To improve grinding efficiency, two sets of abrasive components 342 are designed, and a first rotating shaft is arranged on the first rotating gear 3432. The first rotating shaft is equipped with convex teeth, which are designed in the style of sprockets. At the same time, a second chain 3433 is arranged on the convex teeth. The second chain 3433 meshes with the convex teeth on the first rotating shaft. The rotation of the first rotating gear 3432 and the drive of the first rotating shaft realize the rotation of the two abrasive components 342.

[0046] The first grinding transmission component 344 includes a first transmission sprocket 3441, a first bevel gear 3442, a second bevel gear 3443, and a second transmission gear 3444. The first transmission sprocket 3441 is arranged inside the frame 32. The first bevel gear 3442 is coaxially arranged on the first transmission sprocket 3441. The second bevel gear 3443 is meshed on the side of the first bevel gear 3442. The second transmission gear 3444 is coaxially arranged on the second bevel gear 3443. The second transmission gear 3444 meshes with the first rotating gear 3432, and the second transmission gear 3444 drives the first rotating gear 3432 to rotate. The first bevel gear 3442 and the second bevel gear 3443 are arranged perpendicularly, realizing the steering transmission of power. When the first drive sprocket 3321 transmits power to the first transmission sprocket 3441 via the drive chain assembly 36, the first rotating gear 3432 is driven by the first bevel gear 3442, the second bevel gear 3443, and the second transmission gear 3444, causing the sanding component 342 to rotate and sand the wall surface after scraping. The rotation of the first rotating gear 3432 drives the second chain 3433 on its shaft to rotate, thereby driving the sanding disc 3421 on the other side to rotate. The second transmission gear 3444 and the first rotating gear 3432 are connected to the inside of the frame 32 through bearings, thus enabling them to move within the frame 32. A housing is arranged inside the first sanding cavity 341 to protect the first sanding rotating component 343 and the first sanding transmission component 344, enclosing them to prevent dust from entering and affecting them. The rotating disc 3431 is connected to the housing through bearings and is kept on the same plane as the housing. Holes for sanding rotation and slots for dust to enter are provided on the frame 32.

[0047] Reference Figure 3 and Figure 4 As shown, the first cleaning assembly 35 has a first cleaning cavity 351, which is arranged inside the frame 32. The first cleaning cavity 351 contains a cleaning roller 352 and a first cleaning component 353. The cleaning roller 352 is used for cleaning the wall and can be a brush roller with nylon bristles on its surface, effectively cleaning dust and debris from the wall. The first cleaning component 353 includes a first cleaning sprocket 3531 and a first connecting shaft. The first cleaning sprocket 3531 is coaxially arranged on the cleaning roller 352, and the first connecting shaft is connected to the first cleaning sprocket 3531 to ensure reliable power transmission. When the first drive sprocket 3321 transmits power to the first cleaning sprocket 3531 through the drive chain assembly 36, it drives the cleaning roller 352 to rotate, cleaning the wall surface to be cleaned.

[0048] The drive chain assembly 36 includes a first chain 361, which is arranged on a first drive sprocket 3321, a first transmission sprocket 3441, and a first cleaning sprocket 3531, and the three sprockets are arranged vertically and coaxially. The drive chain assembly 36 enables the first rotating assembly 33, the first grinding assembly 34, and the first cleaning assembly 35 to transmit power synchronously, improving work efficiency, reducing the number of power sources, and lowering equipment costs.

[0049] Reference Figure 4 As shown, a tensioning component is arranged on the side of the drive chain assembly 36. The tensioning component has a first meshing gear 3621, a second meshing gear 3622, a first lever 3623, a first tensioning wheel 3624, a second lever 3625, a second tensioning wheel 3626, and an adjusting knob 3627. The first meshing gear 3621 is arranged inside the frame 32 and meshes with the second meshing gear 3622. The first lever 3623 is arranged on the first meshing gear 3621. The first tensioning wheel 3624 is arranged on the first lever 3623 and meshes with the first chain 361. The second lever 3625 is arranged on the second meshing gear 3622. The second tensioning wheel 3626 is arranged on the second lever 3625 and meshes with the first chain 361. The adjusting knob 3627 meshes with the first meshing gear 3621. When the first chain 361 becomes slack, the first meshing gear 3621 can be rotated by rotating the adjusting knob 3627, which in turn causes the first lever 3623 and the second lever 3625 to move, adjusting the positions of the first tension wheel 3624 and the second tension wheel 3626, thereby tensioning the first chain 361 and ensuring the stability of the transmission.

[0050] Reference Figure 5 and Figure 6 As shown, the frame 32 also includes a suction passage 5, which comprises a first suction channel 51, a second suction channel 52, and a third suction channel 53. The first suction channel 51 is located within the first grinding chamber 341, the second suction channel 52 is located within the frame 32 for the flow of wall plaster scraped off by the first rotating component 33, and the third suction channel 53 is located within the first cleaning chamber 351 for the flow of dust cleaned by the first cleaning component 35. A dust outlet 54 is located at the bottom of the frame 32, and a filter screen 55 is installed on the dust outlet 54. The filter screen 55 can be a metal filter screen 55 or a fiber filter screen 55, capable of filtering large particles of impurities. The dust outlet 54 is connected to a negative pressure vacuum cleaner. When the negative pressure vacuum cleaner is activated, a negative pressure is created within the suction passage 5, drawing out dust and debris from the first grinding chamber 341, the second suction channel 52, and the first cleaning chamber 351 through the dust outlet 54. All dust and powder are collected and stored in a waste collection box, which is placed on the installation basket 1. After the work is completed, the powder in the waste collection box is emptied out for disposal.

[0051] Reference Figure 7 As shown, an electric lifting rod 21 for raising the frame 32 is arranged on the wall-scraping platform 31. The electric lifting rod 21 is hinged to the frame 32, and at least one electric lifting rod 21 is arranged; in this embodiment, two are used, one above the other. The electric lifting rod 21 extends or retracts the entire frame 32, thereby allowing the wall-scraping mechanism 3 to better contact the wall surface and improve the cleaning effect. A shock-absorbing pad is arranged on the back side of the frame 32 to reduce vibration during operation, improving the stability and service life of the equipment.

[0052] The suspended platform 1 is also equipped with a lifting device 6, which is located on the top of the wall. At the same time, a weight block 61 is arranged on the other side of the lifting device 6 to balance the stability of the suspended platform 1. A fall protection rope is also arranged and connected to the suspended platform 1 to further improve the stability and safety of the suspended platform 1.

[0053] The implementation principle of the wall scraping device for old wall renovation according to an embodiment of this application is as follows: The wall scraping device for old wall renovation realizes the flexible movement of the wall scraping mechanism 3 in the horizontal and vertical directions through the sliding mechanism 4, which expands the coverage area of ​​the wall scraping and improves work efficiency. The first rotating component 33, the first grinding component 34 and the first cleaning component 35 in the wall scraping mechanism 3 are synchronously driven by the drive chain component 36, so that the wall surface can be ground and cleaned at the same time as scraping, which meets the requirements of the overall treatment of the wall surface in old wall renovation.

[0054] During the renovation of old walls, the first rotating component 33, positioned in the middle, removes the old wall plaster. The first grinding component 34, positioned above the rotating component 33, uses a grinding disc 3421 to grind the wall surface after plaster removal, smoothing out the unevenness. To address unevenness, the grinding disc 3421 on the first grinding component 34 is flexible and can adjust to the surface's irregularities. The first cleaning component 35, positioned below the rotating component 33, cleans the plaster to be removed, sweeping away dust and particulate impurities. This prevents small particles such as pebbles from adhering to the plaster and damaging the blades 331 on the rotating component 33, thus affecting their lifespan and overall removal efficiency. When the blade on the blade 331 is damaged, the entire blade 331 needs to be replaced. However, since this device is used on the installation basket 1, it is extremely inconvenient for workers to replace the blade 331. Therefore, the risk of damage to the blade 331 can be reduced by cleaning the surface of the wall plaster to be removed by the first cleaning component 35.

[0055] Simultaneously, the first rotating assembly 33, the first grinding assembly 34, and the first cleaning assembly 35 are synchronously transmitted through the drive chain assembly 36. The drive motor 3322 drives the cutter 331 to rotate, thereby rotating the first rotating assembly 33 and providing the entire power source for the drive chain assembly 36. The first grinding assembly 34 and the first cleaning assembly 35 rotate driven by the first rotating assembly 33. The tensioning device arranged on the first chain 361 assembly of the drive chain assembly 36 can rotate the first meshing gear 3621 by rotating the first lever 3623, thereby rotating the first meshing gear 3621 and the second meshing gear 3622, achieving the tensioning effect of the first tensioning wheel 3624 and the second tensioning wheel 3626 on the first chain 361.

[0056] The suction passage 5 and the negative pressure vacuum cleaner can clean up the dust and debris generated during the work process in a timely manner and keep the working environment clean. The fly ash generated after the sanding disc 3421 grinds the wall surface is sucked into the first grinding chamber 341 through the slot on the frame 32. Since a shell is arranged in the first grinding chamber 341, the fly ash will not enter the shell and affect the internal mechanical parts. The fly ash is sucked away from the first suction passage 51.

[0057] The electric lifting rod 21 and shock-absorbing pads are designed to allow the frame 32 to be lifted laterally via the electric lifting rod 21, ensuring a tight fit between the frame 32 and the wall surface for effective removal of the mortar. The hinged arrangement of the electric lifting rod 21 on the frame 32 also facilitates adjustment of the rod's extension and retraction, allowing the frame 32 to tilt to adapt to the wall surface. The shock-absorbing pads reduce vibrations during the removal process, improving the equipment's stability and lifespan. Compared to traditional methods of old wall renovation and mortar removal, this device reduces labor intensity, improves the uniformity and smoothness of the wall surface, avoids mortar residue, and provides a good foundation for subsequent decoration processes.

[0058] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
