Description

Technical Field

[0001] This utility model relates to the field of wall sanding technology, and in particular to a building wall sanding device. Background Technology

[0002] The exterior finish of a wall is divided into interior walls and exterior walls. Wall decoration is an integral part of architectural design. During the construction or decoration process of a building project, wall sanding is a necessary step in the wall treatment process. In order to ensure the flatness of the building's walls and make the walls look more beautiful, it is usually necessary to sand the building's walls to make the walls more uniform and delicate. This requires the use of wall sanding equipment.

[0003] Existing wall sanding equipment often generates a large amount of dust during the sanding process. If the dust is not collected and treated in time, it will float directly in the air, affecting the environmental quality during work and increasing the trouble of cleaning up the dust later. Although some equipment can absorb and treat the dust generated by sanding with a vacuum cleaner, the absorption process lacks measures to concentrate the dust, resulting in poor comprehensiveness of dust absorption and treatment.

[0022] A type of building wall sanding equipment:

[0023] like Figures 1-5 As shown, in this embodiment, a trolley 1 and a grinding frame 2 are included. The grinding frame 2 is located above the trolley 1. A drive motor 4 is fixed in the middle of the left side of the grinding frame 2. The power end of the drive motor 4 is connected to a grinding disc 5. An annular cover 7 is provided around the grinding disc 5. Several ball bearings 8 are rotatably connected to the outer periphery of the left end of the annular cover 7. An elastic protective cover 6 is connected between the annular cover 7 and the grinding frame 2. Spring telescopic rods 9 are provided at both the upper and lower ends of the elastic protective cover 6. The spring telescopic rods 9 are connected between the annular cover 7 and the grinding frame 2.

[0024] When the sanding equipment is used to sand the wall, the trolley 1 moves the equipment and presses the ball bearings 8 against the wall. The annular cover 7 compresses the spring telescopic rod 9 and the elastic protective cover 6 until the sanding disc 5 can sand the wall. At this time, the drive motor 4 drives the sanding disc 5 to rotate, and the sanding disc 5 will sand the wall. When the sanding equipment moves and sands, the ball bearings 8 will roll along the wall, which helps to prevent unnecessary scratches on the wall and ensures the smoothness of the sanding equipment when moving and sanding. Since the annular cover 7 and the elastic protective cover 6 shield and protect the sanding disc 5, when the sanding disc 5 sands the wall and generates dust, the annular cover 7 and the elastic protective cover 6 will block and collect the sanding dust, which helps to concentrate the sanding dust and prevent the dust from flying everywhere.

[0025] like Figures 1-3 As shown, in this embodiment, a vacuum cleaner 3 is fixed on the left side of the upper end of the trolley 1. The vacuum cleaner 3 has a vacuum hose 20 connected to its suction port. An annular tube 21 fixed to the left side of the grinding frame 2 is provided inside the elastic protective cover 6. The end of the vacuum hose 20 is connected to the annular tube 21. Several vacuum covers 22 are connected to the outer periphery of the left end of the annular tube 21.

[0026] When the grinding disc 5 is grinding the wall surface, the dust generated by grinding is concentrated in the annular cover 7 and the elastic protective cover 6, and the dust collector 3 is started at the same time, which is beneficial to the centralized and comprehensive dust absorption through the dust suction cover 22, and the dust is absorbed into the annular pipe 21, the dust suction hose 20 and the dust collector 3, so as to collect and process the dust generated by grinding in time and effectively, ensure the comprehensiveness of dust absorption and processing, and ensure the environmental quality during grinding.

[0027] As shown in Figure 1 In this embodiment, the right side of the upper end of the trolley 1 is fixed with an L-shaped fixing frame 10, the L-shaped fixing frame 10 is slidably sleeved with a lifting plate 11, the upper end of the trolley 1 is fixed with a reversible motor 15, the power end of the reversible motor 15 is connected with a lead screw 16, the lead screw 16 is screwed through the lifting plate 11 upwards, the upper end of the lead screw 16 is rotatably connected to the inner top end of the L-shaped fixing frame 10, the lifting plate 11 is fixed with a support rod 12 at the upper end, the support rod 12 is rotatably connected with a gear 13 at the upper end, and the gear 13 is fixed with an adjusting rod 14 between the gear 13 and the grinding frame 2.

[0028] When it is necessary to adjust the up-down grinding position of the grinding disc 5, the lead screw 16 is driven to rotate by the reversible motor 15, and the lifting plate 11 is driven to slide up and down along the L-shaped fixing frame 10, so that the lifting plate 11 drives the support rod 12, the gear 13, the adjusting rod 14, the grinding frame 2, the driving motor 4 and the grinding disc 5 to move up and down together, so that the grinding disc 5 can be conveniently moved up and down for grinding, and the convenience during grinding is ensured.

[0029] As shown in Figure 4 In this embodiment, the right end of the support rod 12 is fixed with an electric cylinder 17, the power end of the electric cylinder 17 is connected with a sliding block 18, the sliding block 18 is slidably connected with the support rod 12, the upper end of the sliding block 18 is fixed with a toothed plate 19, and the toothed plate 19 is engaged with the gear 13.

[0030] When it is necessary to grind the top end of the wall surface, the sliding block 18 is driven to slide down along the support rod 12 by the contraction of the electric cylinder 17, the sliding block 18 pulls the toothed plate 19 down, the toothed plate 19 is engaged with the gear 13, so that the toothed plate 19 drives the gear 13 to rotate clockwise by ninety degrees, at this time, the gear 13 drives the adjusting rod 14, the grinding frame 2, the driving motor 4 and the grinding disc 5 to rotate clockwise by ninety degrees together, so that the grinding disc 5 can be conveniently turned over upwards, so as to facilitate the grinding of the top end of the wall surface by the grinding disc 5, and as known from the above, it is also beneficial to grind the side of the wall surface, and the applicability of the grinding equipment is ensured.
