Specific Embodiments

[0015] The present utility model will be further described below with reference to the drawings:

[0016] As Figures 1-2 shown, a grinding device for building corners is composed of a cross frame 1, a side pull frame 2 and a limiting arm 3;

[0017] The two ends of the cross frame 1 are slidably inserted with the side pull frame 2. The end of the side pull frame 2 is fixedly installed with a limiting arm 3. The limiting arm 3 is perpendicular to the side pull frame 2. The end of the limiting arm 3 is installed with an inclined caster wheel 4, which is convenient for pressing on both sides of the building corner and facilitating up and down movement;

[0018] The cross frame 1 is connected and installed with an assembled groove frame through an elastic telescopic shaft 5. The elastic telescopic shaft 5 has a compression and rebound function. A rotating sleeve 8 is rotatably installed in the assembled groove frame through a rotating sleeve shaft. There are two groups of rotating sleeves 8. A corner grinding wheel column 9 is installed between the two groups of rotating sleeves 8. The corner grinding wheel column 9 is mainly used for grinding building corners. A grinding motor 7 is installed and fixed on the assembled groove frame. The grinding motor 7 is connected to the rotating sleeve shaft, which is convenient for the corner grinding wheel column 9 to grind building corners;

[0019] A battery box 14 is fixedly installed on the cross frame 1. A storage battery is installed inside the battery box 14, which is convenient for supplying power to the grinding motor 7. A controller 13 is installed on the outer side of the battery box 14, and the controller 13 is electrically connected to the grinding motor 7.

[0020] As Figures 1-2 shown, the present utility model also discloses the following various more optimized specific structures:

[0021] An inner hexagonal groove is provided inside the rotating sleeve 8. On both sides of the angle grinding wheel column 9, six-sided limiting end columns 18 are fixedly installed, and the six-sided limiting end columns 18 are inserted into the inner hexagonal groove. An angle grinding ring groove arc surface 19 is provided on the column surface of the angle grinding wheel column 9, which is convenient for grinding the building corners into a specified arc surface.

[0022] The assembled groove frame is composed of a main groove frame 6 and a side groove pressing frame 10. The main groove frame 6 and the side groove pressing frame 10 are fixedly installed together through side pressing bolts 11. When it is necessary to replace the angle grinding wheel 9, the side groove pressing frame 10 is disassembled, and then the rotating sleeve 8 and the six-sided limiting end column 18 are inserted and fixed after being limited.

[0023] Two sets of pull frame adjusting bolts 16 are rotatably connected to the cross frame 1, and the two sets of pull frame adjusting bolts 16 respectively correspond to the two side pull frames 2. A number of uniformly arranged adjusting holes 12 are provided on the side pull frames 2, and the number of adjusting holes 12 is arranged in a straight line and closely arranged. The end of the pull frame adjusting bolt 16 is inserted into the adjusting hole 12.

[0024] A handle 15 is installed on the battery box 14.

[0025] As Figures 1-2 shown, the grinding device for building corners mainly grinds the building corners. After building construction, the building corners are relatively rough after demolding, and a relatively fine building project requires a grinding machine for grinding. During use, the side pull frame 2 is adjusted according to the outer wall corner 17. After the length of the side pull frame 2 is fixed, the inclined foot wheels 4 are pressed on the two side building surfaces of the building corner, and the angle grinding wheel 9 is pressed on the building corner under the action of the elastic telescopic shaft 5. Through the rolling of the inclined foot wheels 4, rapid grinding is realized during the up and down movement of the corner. The grinding radian and angle of the building corner are changed and adjusted by replacing the angle grinding wheel 9.
