In this embodiment, in the initial state, the lower surface of the second hinge plate 405 is flush with the polishing surface of the polishing plate 400. When the cavity wall with the external corner is polished, the polishing device is pressed downwards, the second hinge plate 405 moves downwards under the action of the pressing plate 306, and a height difference E exists between the second hinge plate 405 and the polishing surface of the polishing mechanism 500, and at this time, the protruding part of the second hinge plate 405 opposite to the polishing mechanism 500 contacts with the other side of the wall, so as to provide a reference for the movement of the whole polishing device.
In this embodiment, rubber strips are attached to the lower edges of the second hinge plate 405 and the support plate 309 to prevent damage to the wall when the polishing apparatus is moved.
The working principle and working process of the building construction surface polishing equipment are as follows:
when the wall at the internal corner is polished, if the internal corner is 90 degrees: then, as shown in fig. 10, the two side walls forming the internal corner are defined as a first wall and a second wall, the polishing surface of the polishing plate 400 contacts with the first wall, when the polishing device approaches to the second wall, the acting force of the second wall received by the first hinge plate 403, the second hinge plate 405 and the sealing plate 404 moves to the side approaching to the connecting rod 402, and the first connecting spring, the second connecting spring and the third connecting spring are pressed, and at this time, the roller 4015 on the hinge sealing plate 4012 is attached to the second wall, so that the polishing device rolls along the wall. When the second hinge plate 405 moves, the sliding plate 401 is driven to move towards the center of the panel 308 along the third chute 304, and the first clamping block 409, the second clamping block 4010 and the hinge shaft 406 drive the hinge sealing plate 4012 to move synchronously. In the process of moving the second hinge plate 405 towards the panel 308, when the protruding block 4011 moves to contact with the abutting block 305, the second hinge plate 405, the sealing plate 404 and the first hinge plate 403 are pushed upwards by the protruding block 4011 under the pushing action of the abutting block 305 and tightly push against the pressing plate 306, so that the second hinge plate 405, the sealing plate 404 and the first hinge plate 403 are further convenient to integrally move towards one side close to the connecting rod 402.
If the internal angle is greater than 90 degrees, as shown in fig. 11, the second hinge plate 405 receives a greater pressure on the second wall than the first hinge plate 403, so that the second hinge plate 405 moves closer to the connecting rod 402 by a greater distance than the first hinge plate 403 moves closer to the connecting rod 402, so that the angle formed between the hinge seal plate 4012 and the sliding plate 401 is the same as the internal angle.
If the internal angle is smaller than 90 degrees, as shown in fig. 12, the pressure of the second wall applied to the first hinge plate 403 is greater than the pressure of the second wall applied to the second hinge plate 405, and the distance that the first hinge plate 403 moves toward the side close to the connecting rod 402 is greater than the distance that the second hinge plate 405 moves toward the side close to the connecting rod 402, so that the included angle formed between the hinge seal plate 4012 and the sliding plate 401 is the same as the internal angle.
When polishing external corners: the two side walls forming the external corner are defined as a third wall and a fourth wall, the polishing surface of the polishing pad 400 is in contact with the third wall, as shown in fig. 13 and 14, the polishing apparatus is pressed downward, the second hinge plate 405 moves downward by the pressing plate 306, and there is a height difference E from the polishing surface of the polishing mechanism 500, at which time the second hinge plate 405 contacts the fourth wall with respect to the protruding portion of the polishing mechanism 500, providing a reference for the movement of the entire polishing apparatus.
