Description

Technical Field

[0001] This utility model relates to the field of wall surface grinding technology, specifically to a wall surface grinding device for building construction. Background Technology

[0002] In the construction industry, wall grinding devices are an indispensable tool in the construction process. They are of great significance for improving construction efficiency, ensuring wall flatness, and enhancing the overall quality of building decoration. However, traditional wall grinding devices still have some technical bottlenecks in practical applications, especially in terms of adapting to different construction environments and wall structures.

[0003] Traditional wall grinding devices are mostly fixed in design and cannot be adjusted according to changes in the construction environment or wall structure. This fixed design often achieves good results when grinding vertical walls, but it is inadequate when changing positions from the wall to the top. Operators often need to frequently change tools or manually adjust the angle of the device, which not only increases the difficulty of construction, but also reduces work efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a wall surface grinding device for building construction to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A wall surface grinding device for building construction includes a mobile cart, the top of which is equipped with a height adjustment structure, the top of which is equipped with a wall surface and wall top conversion grinding structure, and the top of which is equipped with a negative pressure dust collection structure located on the right side of the height adjustment structure.

[0007] The wall and top conversion grinding structure includes a lifting column mounted above a mobile trolley. A support rod is fixedly installed on the top of the lifting column, and a rotating frame is rotatably installed on the top of the support rod.

Detailed Implementation

[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0022] Example 1, as Figures 1-5 As shown, a wall surface grinding device for building construction includes a mobile cart 1. The top of the mobile cart 1 is equipped with a height adjustment structure, and the top of the height adjustment structure is equipped with a wall surface and wall top conversion grinding structure. The top of the mobile cart 1 is equipped with a negative pressure dust collection structure located on the right side of the height adjustment structure.

[0023] Specifically, the wall and top conversion grinding structure includes a lifting column 2 set above the mobile trolley 1. A support rod 3 is fixedly installed on the top of the lifting column 2. A rotating frame 4 is rotatably installed on the top of the support rod 3. A grinding motor 5 that extends through to the top of the rotating frame 4 is fixedly installed inside the rotating frame 4. A grinding block 6 is fixedly installed at the output end of the grinding motor 5. A bearing seat 7 is fixedly installed on the left side of the rotating frame 4. An electric push rod 8 is hinged to the bearing seat 7. The bottom of the electric push rod 8 is hinged to the left side of the lifting column 2.

[0024] In use, driven by the grinding motor 5, the grinding block 6 can rotate and perform grinding operations on the construction wall. To achieve grinding of walls at different heights, the height of the wall surface and top grinding structure can be flexibly adjusted using the height adjustment structure. The rotating frame 4 is firmly restricted above the lifting column 2 by the support rod 3 and is allowed to rotate within a certain range. When grinding is required, the first electric push rod 8 is retracted. Through the linkage of the bearing seat 7, the rotating frame 4, the grinding motor 5, and the grinding block 6 can be pulled to rotate counterclockwise. When the rotating frame 4 and the support rod 3 form a "7" shape, the grinding block 6 is in contact with the wall. In the parallel state, the grinding motor 5 is started, causing the grinding block 6 to rotate and contact the wall, thus smoothing the wall surface. If it is necessary to switch to grinding the top of the wall, the first electric push rod 8 is extended. Through the linkage of the bearing 7, the rotating frame 4, the grinding motor 5, and the grinding block 6 can rotate clockwise. When the rotating frame 4 and the support rod 3 form a straight "1" shape, the grinding block 6 is parallel to the top of the wall. At this time, the grinding motor 5 is started, and the rotating grinding block 6 is made to contact the top of the wall, thus completing the smoothing of the top of the wall. This process realizes the flexible switching between grinding operations on the wall surface and the top of the wall.

[0025] Example 2, as Figures 1-4 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0026] The height adjustment structure includes a rectangular tube 9 fixedly installed on the top of the mobile cart 1, a lifting column 2 slidably installed inside the rectangular tube 9, a connecting block 10 fixedly installed on the front and back of the lifting column 2, and a second electric push rod 11 fixedly installed on the front and back of the rectangular tube 9. The telescopic ends of the two second electric push rods 11 are fixedly connected to the two connecting blocks 10 respectively.

[0027] With this setup, by controlling the extension and retraction of the two No. 2 electric push rods 11, the lifting column 2 between the two connecting blocks 10 can be driven to rise and fall inside the rectangular tube 9. The rise and fall of the lifting column 2 can drive the wall surface and the wall top conversion grinding structure to rise and fall synchronously.

[0028] Example 3, as Figures 1-4 As shown, this embodiment is a further improvement based on embodiment 1, and its specific details are as follows:

[0029] A protective cover 12, which is fitted onto the outside of the grinding block 6, is fixedly installed on the top of the rotating frame 4. The output shaft of the grinding motor 5 is rotatably installed inside the lower bottom wall of the protective cover 12.

[0030] With this configuration, the protective cover 12 can protect the exterior of the grinding block 6 during the grinding operation, thereby reducing the splashing of construction debris during the grinding process.

[0031] Example 4, as Figures 1-4 As shown, this embodiment is a further improvement based on embodiment 2, and its specific details are as follows:

[0032] The negative pressure dust collection structure includes a storage box 13 fixedly installed on the top of the mobile cart 1. The storage box 13 is located on the right side of the rectangular cylinder 9. A filter screen 1301 is slidably installed inside the storage box 13. A negative pressure fan 14 is fixedly installed on the top of the mobile cart 1, located on the right side of the storage box 13. The exhaust end of the negative pressure fan 14 extends into the interior of the storage box 13 and is located on the right side of the filter screen 1301. A telescopic pipe 15 is fixedly installed on the left side of the storage box 13. The telescopic pipe 15 is fixedly installed on the right side of the rectangular cylinder 9, the lifting column 2, and the rotating frame 4. A curved pipe 16 is fixedly installed on the top of the telescopic pipe 15, extending into the interior of the protective cover 12. The curved pipe 16 is located on the back of the rotating frame 4.

[0033] With this configuration, when the negative pressure fan 14 is running, it can effectively draw air from inside the storage box 13, keeping the storage box 13 under negative pressure. Under this negative pressure, through the connection of the telescopic pipe 15 and the curved pipe 16, the storage box 13 can further draw air from inside the protective cover 12. This process not only helps to suck the construction debris generated during the grinding operation into the storage box 13, but also ensures that the debris is effectively intercepted by the built-in filter screen 1301 after entering the storage box, ensuring that the debris is safely stored in the storage box 13. Finally, the treated air will be discharged to the outside as the negative pressure fan 14 continues to operate.

[0034] The telescopic tube 15 is fixedly installed on the right side of the rectangular tube 9, the lifting column 2, and the rotating frame 4. This design naturally divides the telescopic tube 15 into two sections. When the lifting column 2 is raised or lowered, it can pull the telescopic tube 15 to make corresponding extension and retraction adjustments. Similarly, when the rotating frame 4 is rotated to adapt to different angle requirements, it can also pull the telescopic tube 15 to extend and retract, thereby ensuring the continuous stability of the connection between the telescopic tube 15 and the protective cover 12, which is not affected by the operation of the equipment.

[0035] Example 5, as Figure 1 and Figure 4 As shown, this embodiment is a further improvement based on embodiment 4, and its specific details are as follows:

[0036] A sealing plate 17 is hinged to the front of the storage box 13, and the sealing plate 17 is located on the front of the filter screen 1301.

[0037] With this configuration, the front of the storage box 13 can be sealed by the hinged sealing plate 17. After opening the sealing plate 17, the filter screen 1301 can be removed from the inside of the storage box 13, thus achieving the effect of easy cleaning.

[0038] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
