Description

Technical Field

[0001] This utility model relates to the field of wall construction technology, and in particular to an integrated device for repairing and cleaning wall grout joints. Background Technology

[0002] The exterior walls of a historical preservation and restoration project are made of exposed blue bricks, with some areas featuring red exposed blue brick moldings; all are key protected areas. An investigation revealed that some sections of the exposed blue brick wall are severely weathered and have experienced significant settlement and deformation. The exposed blue brick walls continue to be finished with the original ingot-shaped grout lines. Grouting with ingot-shaped joints requires a high level of skill, and the choice of grouting tools directly affects the quality of the grouting. Current technology typically uses hand-held grouting tools with a semi-circular tube at the front for manual operation. During restoration, wall repair requires not only re-grouting but also cleaning of damaged areas. Using conventional grouting tools is not only a test of the worker's hand dexterity and skill but also a test of their physical strength, making it unsuitable for long-term use. Therefore, we propose an integrated device for repairing and cleaning wall grout joints. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides an integrated device for repairing and cleaning wall grout joints.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A wall grout repair and cleaning integrated device is designed, including a housing with a power supply handle at the bottom. Inside the housing is a drive shaft driven by a servo motor. Rotary shafts are respectively connected to both sides of the drive shaft. The ends of the rotating shafts pass through the housing and are respectively equipped with cutting discs and cleaning discs. The cutting discs are uniformly equipped with diamond heads around their circumference, and the cleaning discs are uniformly equipped with brush heads around their circumference. Support blocks fixed to the housing are movably installed on the rotating shafts located outside the housing. A limit plate is movably connected to the top of one of the support blocks.

[0006] In the above scheme, a bevel gear one is installed on the drive shaft, and a bevel gear two that meshes with the bevel gear one is installed on the rotating shaft.

[0007] In the above scheme, the top of the power supply handle is connected to the housing via an electrical connector.

[0008] In the above scheme, the limiting plate has an installation groove on the side away from the cleaning disc, and a rubber strip is installed in the installation groove.

[0009] In the above scheme, a limiting plate two is movably connected to the top of the other side support block, and the limiting plate two is provided with a nozzle facing the cleaning disc on the side away from the cutting disc.

[0010] In the above scheme, the top of the support block is fixed with an adjustment groove, and the first and second limiting plates are threaded with adjusting screws that cooperate with the adjustment groove.

[0011] In the above scheme, the nozzle is connected to the limiting plate 2 via a pipe clamp, and a water supply connector is connected to the tail of the nozzle.

[0012] In the above scheme, a reinforcing frame is fixed between adjacent support blocks, and a support frame is fixed between the reinforcing frame and the housing.

[0013] The advantages and beneficial effects of this utility model are as follows: By setting up a housing, power supply handle, drive shaft, servo motor, rotating shaft, cutting disc, cleaning disc, diamond head, and brush head, the servo motor provides power to make the drive shaft rotate, which in turn drives the rotating shaft to make the cutting disc and cleaning disc rotate. At the same time, the diamond head rotates around the cutting disc and the brush head rotates around the cleaning disc. Compared with the prior art, it can not only complete the grouting work on the wall, but also clean the residue in the gap. As the user's hand moves along the gap, the grouting and cleaning work can be carried out simultaneously, reducing the burden on the workers, saving time and effort, and making it convenient to use. By setting up a support block and a limiting plate, the distance between the end of the extended edge of the limiting plate and the outer diameter edge of the cutting disc can be adjusted by moving the limiting plate. Compared with the prior art, the cutting depth of the diamond head can be adjusted to adapt to different construction needs. Attached Figure Description

[0020] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: an integrated device for repairing and cleaning wall grout joints, including a housing 1 with a power supply handle 2 at the bottom;

[0022] Furthermore, the top of the power supply handle 2 is connected to the housing 1 via an electrical connector; the power supply handle 2 and the housing 1 can be separated by disassembling the electrical connector.

[0023] Specifically, the power supply handle 2 provides electrical energy to the entire utility model. The power supply handle 2 can be replenished by replacing the battery or by charging.

[0024] The housing 1 is equipped with a drive shaft 4 driven by a servo motor 3. The drive shaft 4 is connected to the servo motor 3. Rotary shafts 6 are connected to both sides of the drive shaft 4. Both the drive shaft 4 and the rotating shafts 6 are movably connected to the inner wall of the housing 1.

[0025] Furthermore, a bevel gear 5 is mounted on the drive shaft 4, and a bevel gear 7 that meshes with the bevel gear 5 is mounted on the rotating shaft 6. When the drive shaft 4 rotates, the bevel gear 5 drives the bevel gear 7 to rotate, which in turn causes the rotating shaft 6 to rotate.

[0026] The ends of the rotating shaft 6 all penetrate the casing 1 and are respectively equipped with cutting discs 8 and cleaning discs 10. The cutting discs 8 are evenly equipped with diamond heads 9 around their circumference, and the cleaning discs 10 are evenly equipped with brush heads 11 around their circumference. Figure 1 As shown, the diamond head 9 and the brush head 11 are respectively connected to the cutting disc 8 and the cleaning disc 10 by fasteners;

[0027] Specifically, by setting up a housing 1, a power supply handle 2, a drive shaft 4, a servo motor 3, a rotating shaft 6, a cutting disc 8, a cleaning disc 10, a diamond head 9, and a brush head 11, the servo motor 3 provides power to rotate the drive shaft 4, which in turn drives the rotating shaft 6 to rotate the cutting disc 8 and the cleaning disc 10. At the same time, the diamond head 9 rotates around the cutting disc 8 and the brush head 11 rotates around the cleaning disc 10. Compared with existing technologies, this not only completes the grouting work on the wall but also cleans the residue in the gaps. As the user moves their hand along the gap, grouting and cleaning can be performed simultaneously, reducing the burden on workers, saving time and effort, and making it convenient to use.

[0028] Support blocks 12, which are fixed to the housing 1, are movably installed on the rotating shaft 6 located on the outside of the housing 1.

[0029] Furthermore, a reinforcing frame 22 is fixed between adjacent support blocks 12, and a support frame 23 is fixed between the reinforcing frame 22 and the housing 1. The stability of the rotating shaft 6 and the support block 12 is improved by using the reinforcing frame 22 and the support frame 23.

[0030] A limit plate 14 is movably connected to the top of one side support block 12;

[0031] Furthermore, the limiting plate 14 has a mounting groove 21 on the side away from the cleaning disc 10, and a rubber strip 20 is installed in the mounting groove 21. In actual application, the side of the limiting plate 14 is pressed against the wall, and the diamond head 9 is located in the gap. The rubber strip 20 effectively prevents the limiting plate 14 from being excessively worn during use.

[0032] Specifically, by setting support block 12 and limiting plate 14, and by moving limiting plate 14, the distance between the end of the edge extension line of limiting plate 14 and the outer diameter edge of the cutting disc 8 can be adjusted. Compared with the existing technology, the cutting depth of the diamond head 9 can be adjusted to adapt to different construction needs.

[0033] Furthermore, the top of the other support block 12 is movably connected to a limiting plate 2 16. The limiting plate 2 16 is provided with a spray pipe 17 facing the cleaning disc 10 on the side away from the cutting disc 8. Water is sprayed into the gap using the spray pipe 17, which can achieve the purpose of cleaning the gap and reducing dust, as well as moisturizing the gap.

[0034] Furthermore, the nozzle 17 is connected to the limiting plate 16 via the pipe clamp 18, and a water supply connector 19 is connected to the tail of the nozzle 17. The other end of the water supply connector 19 is connected to the water supply pipe to supply water to the nozzle 17.

[0035] Furthermore, the top of the support block 12 is fixed with an adjustment groove 13, and the first limiting plate 14 and the second limiting plate 16 are threaded with adjusting screws 15 that cooperate with the adjustment groove 13; by loosening the adjusting screws 15 and moving the first limiting plate 14 and the second limiting plate 16, the relative position of the first limiting plate 14 and the second limiting plate 16 with the support block 12 can be adjusted.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
