Description

Technical Field

[0001] The utility model relates to the field of construction and is particularly suitable for plastering operations. Background Art

[0002] The prior art level has a known device patent CN107905511A "Material surface leveling robot and material leveling method", which is used to level the working wall plastering mixture with the help of a movable mechanical structure. The disadvantage of this technical solution is that it cannot plaster the surface outside the range of the plastering board.

[0003] The prior art also includes a device in US Pat. CIIIA US10161143B2, "Plastering machine having foldable upright rail", which has a similar purpose: plastering a wall surface by means of the movement of a leveling device. The disadvantage of this technical solution is that it can only plaster in a linear mode (vertical or horizontal).

[0004] The state of the art also includes plastering robots (https: / / www.youtube.com / watch?v=b-VnxAGyy9Q, released in 2021; https: / / www.youtube.com / shorts / WG8cRBLxQcw, released on July 21, 2022; https: / / www.youtube.com / watch?v=6sxb9Phvlfo, released in 2020), which can automatically level the plaster layer. The disadvantage of this device is that the level of the plaster layer of the device must be set manually, and it can only be leveled on the vertical surface, which means that the device must be moved along the wall to level the entire wall surface and repeatedly adjust the level. After the device completes the work, the joints between the plaster surfaces must be manually repaired to ensure that the wall surface is completely flat.

[0005] The existing state of the art includes an automatic leveling device for a plaster layer (https: / / www.youtube.com / watch?v=O-FswYUdMdA, published in 2014; https: / / www.youtube.com / watch?v=ukZ-e4pGDb4, published in 2014). The disadvantage of this device is that it can only work on a horizontal surface.

[0006] The prior art also includes a plastering layer leveling device (https: / / www.youtube.com / watch?v=bZHqdnr_2UQ, published in 2014), in which a leveling member moves linearly along an axis, and the axis can change its inclination angle, so that diagonal plastering layers can be leveled. The disadvantage of this technical solution is that there is a "blind spot" - if the wall length is greater than the device length, the device must be moved and leveled to level the entire wall.

[0007] There is also a "plastering robot" in the prior art (https: / / www.youtube.com / watch?v=YME5FglmHFc, release date: 2022), which has a similar purpose to the solution applied for - automatically leveling the plaster layer. However, the device requires manual setting of the working level. In addition, the joint position needs to be manually leveled after the device completes the work.

[0008] The technical solution currently applied for is to solve the defects existing in the above-mentioned technology. Utility Model Content

[0009] The utility model provides a device with the main technical task of leveling a plastered wall surface without leaving any joints. This effect is achieved thanks to the structure of the working mechanism (plastering plate) of the device, which can enable the device to rotate in a circular manner, move linearly, and move in all directions.

[0010] The technical effect of the present application is to ensure a seamless and smooth plastering surface.

[0011] The technical effect is achieved thanks to the wall leveling device containing a structure that is interconnected in structure and function, the structure is installed on rollers and electric-driven hoists (the structure with 4 rollers and 4 hoists is the preferred but not the only solution), the structure is equipped with spatial attitude, horizontal and distance sensors, laser indicators, and a control module with data input and output interfaces, and has a longitudinal and lateral movement system for the plastering board. The plastering board is connected to a rotating device, and the characteristic is that the plastering board can move linearly or circularly, and can move in any direction (up, down, left, and right). The function of the plastering board to automatically change its attitude (changing the rotation angle, the length of the plastering board, and the inclination relative to the wall) ensures the leveling of the entire plastered wall without leaving a "blind spot", which is an area that cannot be covered by the working area of ​​the plastering board.

[0012] The applied utility model device is used to level the wall plaster surface in the following manner: the wall is pre-plastered, the plastering mixture is spread on the wall, the wall leveling device is installed parallel to the plastering surface with the help of a laser pointer, the control module is turned on, the "horizontal setting" mode is selected, and then the level sensor installed on the device sends a signal to the crane through the control module, and the crane lifts the device to the necessary level. Thereafter, the operator selects the device working mode (the device includes a software and hardware system control module, through which the device is used in different modes: in manual mode, the plastering board and the control module are forced to move along the track guide; in automatic mode, the control module can be moved or not), the device is started, so that it uses the distance sensor to determine the working surface in automatic mode and level the plastering surface. At this time, the device itself moves linearly along the wall, and the leveling component can move linearly or rotate in a circle to move in the required direction. BRIEF DESCRIPTION OF THE DRAWINGS
