Polishing device for building wall

Abstract

The invention discloses a building wall grinding device, comprising a bottom plate, a plurality of telescopic rods are vertically fixed on the upper side of the bottom plate, a supporting plate is horizontally arranged on the telescopic rods, a first positioning column is located on the left side of the second positioning column, and a third positioning column is located on the left side of the second positioning column. A positioning column and a second positioning column are arranged perpendicular to the side of the vertical plate; a side of the vertical plate away from the first positioning column and the second positioning column is pivotally hinged with a rotating shaft, and the casing is on the same side as the first positioning column and the second positioning column. The surface is hinged with a sliding sleeve, and the sliding sleeve is slidably provided with a sliding shaft; the structure of the invention is ingenious, and the expansion and contraction of the telescopic hydraulic cylinder can realize the adjustment of the grinding thickness of the wall by the sand board, and under the elastic force of the limit spring, the grinding The process has a good buffering and shock absorption effect, and the angle of the sleeve can be adjusted by pulling the handle, which can not only grind the vertical wall, but also grind the top wall. It has high performance and greatly improves the wall grinding efficiency of the present invention.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a construction wall grinding device. Background technique [0002] Buildings are structures built by people using all available materials such as soil, stone, wood, steel, glass, reeds, plastics, and ice. Architecture itself is not an end, the purpose of architecture is to obtain the "space" formed by architecture. It is an artificial environment created by people in order to meet the needs of social life, using the material and technological means they have mastered, and using certain scientific laws, feng shui concepts and aesthetic principles. [0003] In the process of building construction, it is necessary to perform wall grinding on the completed building wall to achieve a smooth wall surface and facilitate the application of putty powder and other paints on the wall.

Problems solved by technology

[0003] In the process of building construction, it is necessary to perform wall grinding on the completed building wall to achieve a smooth surface of the wall and facilitate the application of putty powder and other paints on the wall. Most of the existing building wall grinding methods use manual hand-held Sandpaper rubs and grinds the wall surface, the grinding efficiency is low, and the grinding effect is not good. There are also machines for wall grinding, but the existing grinding machines are poor in adjustment, and the adjustment is not flexible enough.
