In addition, the current building size and height are very large, and the requirements for reducing errors in the construction operation process are also higher. Plastering the wall is one of the more important operations in the construction industry. In order to ensure the flatness of the wall in the later processing and the uniformity of the paint, the early plastering work is also very important.

[0045] The working principle of a high-precision masonry wall thin plastering machine proposed by the embodiment of the present invention is as follows:

[0046] When the plastering machine is moved to one side of the masonry wall by the mobile platform 1 through the universal self-locking wheel 2, the top and bottom of the plastering machine are adjusted to the same spacing position as the masonry wall by using the first distance measuring sensor 3 and the second distance measuring sensor 9, and the positioning plate 8 is pushed by the output end of the electric telescopic rod 7 so that the positioning plate 8 is attached to and positioned on the top of the wall, so as to be adjusted to a state of high-precision plastering;

[0049] When the two sets of dual-axis motors 596 are not working, the reset effect of the tension spring 595 is used to drive the sleeve 592 to move to one end of the guide rod 591, so that the line laser contour sensor 594 at one end of the linkage rod 593 moves to the side of the mortar layer of the masonry wall, which is used to detect the color, glossiness and surface defects of the mortar layer during the plastering process in this direction, as well as the functions of concave-convex defect detection, step difference detection, flatness detection and height difference detection. When the two sets of dual-axis motors 596 are working, the sleeve 592 is pulled during the winding process of the traction rope 598, so that the line laser contour sensor 594 at one end of the linkage rod 593 moves to the other side of the mortar layer of the masonry wall, which is used to expand the detection range of the line laser contour sensor 594.
