The utility model is mainly used to protect mechanical devices, so the utility model no longer explains the control method and circuit connection in detail.

[0040] The working principle of the wall grinding device for building construction provided by the utility model is:

[0041] First, move the device to a suitable position, control the extension and retraction of the hydraulic rod, drive the support plate 16 to move, separate the universal wheel 4 from the ground, and complete the fixing of the device;

[0042] Secondly, the output shaft of the driving motor 3 is controlled to rotate, and the rotation of the output shaft drives the connected threaded rod to rotate, and the threaded rod drives the threaded moving block to slide in the slide groove, and cooperates with the moving grooves arranged on both sides of the slide groove, so that the sliding block and the support seat 14 welded on the top of the moving block can move along the X-axis, which is used to adjust the distance between the polishing wheel 18 and the building wall;

[0043] The two nuts 20 are turned to adjust the position of the dust cover 9 according to the use of the polishing wheel 18, and then the polishing wheel 18 is connected to one end of the screw 21 through the fastener 19 to complete the fixation of the polishing wheel 18. At this time, the slider is driven by the linear motor to move along the Y axis, and the movable plate 12 can be raised along the four guide rods 10 under the action of the electric push rod 13. Then, the output shaft of the rotary motor 11 is controlled to rotate, driving the polishing wheel 18 fixed on the screw 21 to rotate, and cooperate with the sealing ring 17 set on one side of the dust cover 9 so that it abuts against the wall surface of the building exterior wall;

[0044] Finally, the vacuum cleaner arranged inside the collecting barrel 7 is controlled to rotate. When the polishing wheel 18 is working, the dust generated by its work enters the collecting barrel 7 through the hose and is concentrated in the material trough. The material trough and the collecting trough 23 are detachably connected. The collecting trough 23 is extracted by a handle arranged at one end of the collecting trough 23, and the dust collected in the material trough can be cleaned.
