Description

Technical Field

[0001] The invention relates to the technical field of wall surface grinding, and more particularly to a wall surface grinding device for house construction. Background Art

[0002] With the continuous improvement of people's living standards and the vigorous development of the interior decoration industry, the requirements for the artistic modeling of interior wall decoration are becoming increasingly diversified and refined. Among the many forms of wall decoration, grille panels are widely used as a decorative material that combines beauty and functionality.

[0003] During the construction of the grille wall, after the putty is scraped, the grinding process is crucial to obtain a flat and smooth surface to meet the subsequent decorative effect and quality requirements. However, the current traditional grinding method mainly relies on manual operation. This method has many significant disadvantages.

[0004] From the perspective of labor intensity, due to the unique grid structure of the grating plate, the uneven surface and the presence of numerous grooves and protrusions, construction workers need to hold the grinding tools for a long time and repeatedly perform grinding operations at different angles and positions, which is extremely labor-intensive. This is not only a severe test of the physical strength of the construction workers, but also easily leads to fatigue work of the construction workers, thus affecting the construction quality and efficiency.

[0005] In terms of construction cycle, manual grinding is relatively slow, especially for large-area grille walls, which takes a lot of time to complete the entire grinding process. For example, if a medium-sized indoor grille wall is manually polished, it may take several days or even longer to achieve the desired polishing effect, which undoubtedly greatly prolongs the construction cycle of the entire wall decoration project.

[0006] In addition, the quality consistency of manual polishing is difficult to ensure. The technical levels and operating habits of different construction workers vary, which can easily lead to uneven flatness and smoothness of the wall after polishing. Additional repairs and rework may be required, further increasing the cost and time investment.

[0007] In summary, the existing manual grinding method of grille walls can no longer meet the growing market demand and the requirements of efficient and high-quality construction. Therefore, there is an urgent need for a device specifically used for grinding grille walls after puttying to reduce labor intensity, shorten construction period, improve construction quality and reduce cost; in view of this, we propose a wall grinding device for house construction.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention improves the structure of the existing wall grinding device by arranging a grinding mechanism at the moving end of the lifting mechanism, and drives the bevel gear transmission component to rotate through the motor of the grinding mechanism, and the bevel gear transmission component drives the shaft rotation component to rotate, and adjusts the connection state of the movable component and the shaft rotation component through the mold adjustment component, so that the whole rotation component and the self-rotation component drive the whole grinding component and the intermediate grinding component to form a plane grinding state or an intermediate groove grinding state.

[0069] S1.2. If the grille wall needs to be polished, the driving motor 2095 drives the rotating rod 2096 and the driving gear 2097 to rotate. The driving gear 2097 meshes with the spur rack A2098 at the top and the spur rack B2099 at the bottom and moves in opposite directions on the slideway 2093. The spur rack A2098 drives the synchronous frame 2053 to move. The synchronous frame 2053 pushes the rotating push rod 2052. The rotating push rod 2052 pushes the self-rotating gear 2051 out. , the self-rotating gear 2051 pushes the grinding block 2071 and the grinding blade B2072 until they are completely pushed out of the rotating through hole 2063. At this time, the grinding block 2071 and the grinding blade B2072 completely protrude from the rotating through hole 2063. At the same time, the spur rack B2099 pulls the fixed plug block 2082 to drive the movable plug rod 2081 to move in the opposite direction. The fixed plug block 2082 at the other end is separated from the fixed connection block 2033 on the central gear 2032, forming a state where the inter-groove is ground flat;

[0070] S2, wall surface smoothing operation;

[0071] The driving motor 201 drives the bevel gear transmission assembly 202 to rotate, the bevel gear transmission assembly 202 drives the shaft rod 2031 to rotate, the shaft rod 2031 drives the central gear 2032 to rotate, and the central gear 2032 drives the fixed block 2033 and the fixed groove 2034 to rotate synchronously;

[0072] When the movable component 208 and the fixed connection groove 2034 of the fixed connection block 2033 are in a non-plugged state, the shaft rotation component 203 rotates, the central gear 2032 engages to drive the self-rotation component 205 to rotate, the self-rotation component 205 engages to drive the inner tooth groove 2044 to drive the full-rotation outer ring 2042 to rotate, and the full-rotation outer ring 2042 drives the fixedly connected shell chassis 2041 to rotate, so that the self-rotation component 205 drives the intermediate grinding component 207 to rotate for grinding;

[0073] When the movable component 208 and the fixed connection groove 2034 of the fixed connection block 2033 are in the plug-in state, the rotation of the shaft rotating component 203 directly drives the movable component 208 to rotate. Since the movable component 208 is inserted into the fixed socket 2045, the movable component 208 drives the shell chassis 2041, the rotating outer ring 2042 and the grinding component 206 to rotate as a whole for grinding;
