Description

Technical Field

[0001] This invention relates to the technical field of wall leveling equipment, specifically to a large-area wall leveling device and method. Background Technology

[0002] The construction process inevitably involves building walls. During this process, putty and paint are applied to the walls for aesthetic purposes. To ensure the adhesion of subsequent painting and latex paint, the surface of the wall needs to be smooth when cement is applied. Therefore, it is necessary to smooth the surface after each cement application.

[0003] According to the publication number "CN110625820B" on "A Building Wall Scraping Device", it is proposed that "in the construction process, it is necessary to scrape the concrete wall in advance to ensure the flatness of the wall surface and facilitate subsequent wall painting. The current wall scraping device relies on the operator to manually scrape the wall, which has a poor scraping effect and easily generates a lot of dust during the scraping process, posing a significant health hazard to the operator."

[0004] The aforementioned technical solution involves installing a leveling mechanism on the guide rail to level the wall, preparing it for subsequent processes; installing a clamping mechanism inside the housing to hold the wall in place for the leveling mechanism to level it; and installing a vacuum cleaner to remove the dust generated during the leveling process. This device enables automatic wall leveling, eliminating the need for manual operation and reducing labor intensity. Furthermore, the vacuum cleaner ensures dust-free leveling, improving the working environment and benefiting the physical and mental health of the operators.

[0005] Current leveling devices are mostly used for leveling by vertical lifting or horizontal movement. This method requires a drive to move the scraper passively across the wall, and the wall is leveled by the flatness of the scraper. This method is too simple and the coverage area is limited at one time. Multiple operations are required to ensure the leveling effect. Therefore, a leveling device is needed. Summary of the Invention

[0006] To address the aforementioned problems, this invention proposes a large-area wall leveling device and method to achieve efficient leveling of large-area walls.

[0007] According to a first aspect of the present invention, a large-area wall leveling device is provided, comprising a base, a sliding plate provided on the top of the base, a lifting plate provided in the top side wall of the sliding plate away from the base, an output end of the lifting plate connected to a mounting box, a leveling plate provided on one side of the mounting box, a plurality of linkage columns provided on the side of the leveling plate away from the mounting box, wherein the middle linkage column is connected to the middle of the side wall of the leveling plate, and the linkage columns near both ends are rotatably connected to the leveling plate, and a rotating scraper is connected to the end of the linkage column away from the leveling plate; an inner groove is provided in the leveling plate, and a follower column is rotatably connected to the inner groove near both ends, a gear is connected to the follower column, a chain is meshed on the gear, and a top column is connected to the middle of the side wall of the sliding plate; The motor is detachably embedded in the mounting box. The back sealing plate is snapped to the side wall opposite to the mounting box. A through hole is provided in the middle of the back sealing plate. One end of the follower column is rotatably connected to the side wall of the back sealing plate. The output end of the motor extends into the inner groove through the through hole. The output end is detachably connected to the middle side wall of the inner groove by screws. A gear is connected to a section of the output end located in the inner groove and meshes with a chain. The follower column is connected at one end to the end of the linkage column that extends into the inner groove.

[0008] As a further improvement of the present invention, the mounting box is detachably connected to the output end of the lifting plate by screws, and a rotating groove is provided in the middle of the top side wall of the translation plate. The lifting plate is rotatably connected to the rotating groove through its bottom end, and a side groove is provided in the middle of the side wall inside the rotating groove.

[0009] As a further improvement of the present invention, an annular side plate is connected to one end of the lifting plate located in the rotating groove. The side plate is rotatably connected in the side groove. A damping rubber ring is connected to the outer ring wall of the side plate away from the lifting plate. The damping rubber ring is in contact with the inner wall of the side groove.

[0010] As a further improvement of the present invention, a sliding groove is provided in the middle of the top side wall of the base, and a slider is slidably connected in the sliding groove. The slider is connected to the middle of the bottom side wall of the translation plate through its top end. A screw is rotatably connected in the sliding groove, and a knob is rotatably connected in the middle of the outer wall of one side of the base. One end of the knob extends into the sliding groove and is connected to one end of the screw.

[0011] As a further improvement of the present invention, rollers are connected to the four corners of the bottom side wall of the base.

[0012] As a further improvement of the present invention, a limiting groove is provided in the middle of the opposite side walls of the slide groove, and a limiting block is slidably connected in the limiting groove. The limiting block is connected in the middle of the two side walls of the slider that are far apart from each other.

[0013] As a further improvement of the present invention, four pairs of support columns are connected to the top of the base and the side walls on both sides of the slide groove. Each support column has a ball bearing rotatably connected to its top side wall, and the ball bearing is in close contact with the bottom side wall of the translation plate.

[0014] According to a second aspect of the present invention, a method for leveling large-area walls is also provided, employing a large-area wall leveling device as described in the first aspect.

[0015] The present invention has the following advantages: the device is moved to the designated position, the sliding plate is extended as needed, the adjustment and movement are stopped when the top column contacts the lifting box on the wall, and then the motor is started. The motor drives the rotating scraper to rotate, and at the same time drives the rotating scrapers located at both ends to rotate, thereby leveling the wall surface. As the device moves and rises, it can efficiently level the wall surface. It can level a large area each time, and a single position can be processed multiple times, effectively improving the processing efficiency and eliminating the need for repeated processing later.

[0018] The invention will now be further described with reference to the accompanying drawings.

[0019] Please refer to the following: Figure 1-6This invention discloses a large-area wall leveling device, comprising a base 1, a sliding plate 2 on the top of the base 1, a lifting plate 4 on the top side wall of the sliding plate 2 away from the base 1, an installation box 5 connected to the output end of the lifting plate 4, a leveling plate 7 on one side of the installation box 5, and several linkage columns 9 on the side of the leveling plate 7 away from the installation box 5, wherein the middle linkage column 9 is connected to the middle of one side wall of the leveling plate 7, and the linkage columns 9 near both ends are rotatably connected to the leveling plate 7, and a rotating scraper 8 is connected to one end of each linkage column 9 away from the leveling plate 7, an inner groove is provided in the leveling plate 7, and a follower column 14 is rotatably connected to the inner groove near both ends, a gear 10 is connected to the follower column 14, and a chain 11 is meshed with the gear 10, and a top column 3 is connected to the middle of one side wall of the sliding plate 2.

[0020] A motor 6 is detachably embedded in the mounting box 5. A rear sealing plate 12 is snapped onto the side wall opposite to the mounting box 5. A through hole 13 is provided in the middle of the rear sealing plate 12. One end of the follower column 14 is rotatably connected to the side wall of the rear sealing plate 12. The output end of the motor 6 extends into the inner groove through the through hole 13, and the output end is detachably connected to the middle side wall of the inner groove by screws. A gear 10 is connected to the section of the output end of the motor 6 located in the inner groove, and it meshes with the chain 11. Two follower columns 14 are connected at one end to the end of the linkage column 9 extending into the inner groove.

[0021] Furthermore, casters are connected to the four corners of the bottom of the base 1 to facilitate the movement and handling of the equipment.

[0022] After moving the equipment to the designated position, adjust the position of the translation plate 2 as needed. When one end of the top column 3 contacts the wall, it means that the rotating scraper 8 is in contact with the wall. This avoids excessive movement that could cause the rotating scraper 8 to squeeze the wet cement surface and affect subsequent processing.

[0023] After the above adjustments, motor 6 is activated to drive the leveling plate 7 to rotate. Considering that a rotating scraper 8 is connected to the middle of the leveling plate 7, its rotation causes it to rotate on its own axis. Simultaneously, via chain 11, this drives the rotating scrapers 8 located at both ends to rotate synchronously. When the leveling plate 7 rotates, it drives several rotating scrapers 8 to perform a synchronized leveling operation on the wall surface. Furthermore, since there are two rotating scrapers 8 at both ends, the coverage area of ​​the leveling operation is increased, thereby increasing processing efficiency. At the same time, the rotation of the leveling plate 7 drives the rotating scrapers 8 at both ends to perform circular motion, thus ensuring that the processing area can be leveled multiple times without requiring subsequent equipment restarts.

[0024] In this embodiment of the invention, the rotating scraper 8 can rotate to cooperate with the movement of the equipment to increase the leveling effect and efficiency; the rotating scraper 8 can rotate to realize automatic leveling operation, avoiding the constraints of passive leveling.

[0025] The above-mentioned technical solutions can effectively improve the efficiency of leveling, and because multiple leveling operations can be performed on-site, costs can be saved by eliminating the need for repetitive labor later.

[0026] For further details, please refer to the following: Figure 1 and 5 The mounting box 5 is detachably connected to the output end of the lifting plate 4 by screws. A rotating groove 15 is provided in the middle of the top side wall of the translation plate 2. The lifting plate 4 is rotatably connected to the rotating groove 15 through its bottom end. A side groove 16 is provided in the middle of the side wall inside the rotating groove 15. An annular side plate 17 is connected to the side wall of the lifting plate 4 located in the rotating groove 15. The side plate 17 is rotatably connected to the side groove 16.

[0027] In addition, a damping rubber ring 18 is connected to the outer wall of the side plate 17 away from the lifting plate 4, and the damping rubber ring 18 is in contact with the inner wall of the side groove 16.

[0028] By rotating the lifting plate 4, the angle of the finding plate 7 can be adjusted. Considering that sometimes the wall itself is inclined, although the equipment itself can be rotated to adapt to the inclined wall, this kind of rotation of the equipment itself is not convenient. The lifting plate 4 is set to be a rotatable structure, so there is no need to move the equipment itself, thus improving convenience and adaptability.

[0029] To prevent the rotating lifting plate 4 from moving easily, the damping rubber ring 18 is provided to increase the friction between the side plate 17 and the side groove 16, so that the lifting plate 4 will not rotate without sufficient external force. The side plate 17 and the side groove 16 ensure the stability of the lifting plate 4. The lifting plate 4 can drive the leveling plate 7 to move up and down, thereby performing a comprehensive leveling treatment on the wall surface.

[0030] For further details, please refer to the following: Figure 1 , 4 6. A groove 19 is provided in the middle of the top side wall of the base 1. A slider 20 is slidably connected in the groove 19. The slider 20 is connected to the middle of the bottom side wall of the translation plate 2 through its top end.

[0031] A screw 22 is rotatably connected inside the slide groove 19, and a knob 21 is rotatably connected to the middle of one side of the outer wall of the base 1. One end of the knob 21 extends into the slide groove 19 and is connected to one end of the screw 22.

[0032] Rollers are connected to the four corners of the bottom side wall of the base 1. Limiting grooves 25 are opened in the middle of the opposite side walls of the slide groove 19. Limiting blocks 26 are slidably connected in the limiting grooves 25. The limiting blocks 26 are connected in the middle of the two side walls of the slider 20 that are far apart from each other.

[0033] In addition, four pairs of support columns 23 are connected to the top of the base 1 and the side walls on both sides of the slide groove 19. Each support column 23 has a ball bearing 24 rotatably connected to its top side wall, and the ball bearing 24 is in close contact with the bottom side wall of the translation plate 2.

[0034] This invention also provides a method for leveling large-area walls. In use, the base is moved to a suitable position to ensure that the rotating scraper is in contact with the wall surface. Then, the motor is started to drive the leveling plate to rotate. As the rotating scraper rotates, it can level the wall surface. Because it is a rotating leveling method and the rotating scraper itself does not move, it can effectively level the wall surface.

[0035] Furthermore, the multiple rotating scrapers can ensure the leveling coverage area, and the leveling efficiency can be directly improved as the equipment moves, and the effect of multiple leveling can be achieved without the need to use the equipment for leveling multiple times later. Furthermore, several rotating scrapers can revolve around a central axis and rotate on their own axis. Revolving around a central axis can increase the coverage area of ​​the scraping, while rotating on their own axis can ensure the scraping effect on individual areas. Moreover, by revolving around a central axis, the wall surface can be repeatedly treated, increasing the effectiveness of the scraping.

[0036] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.

[0037] Other parts of this invention that are not detailed herein are all prior art and will not be described further here.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
