[0030] Example 1

[0031] The various embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0032] Figures 1-4The structure of a grouting construction device is described in general. Specifically, Figure 1 This is a structural schematic diagram of a grouting construction device according to an embodiment of the present utility model. Figure 2 This is another structural schematic diagram of a grouting construction device according to an embodiment of the present utility model; Figure 3 This is a schematic diagram of the pipe cleaning assembly according to an embodiment of the present utility model; Figure 4 This is a schematic diagram of the structure of the stirring assembly according to an embodiment of the present utility model.

[0033] like Figure 1 As shown, this utility model provides a grouting construction device, including a grout tank 3 for preparing cement grout, a vehicle body 1 for setting the grout tank 3, a grouting pump 5 for providing driving force for grouting, and a grouting pipe 6 provided at the output end of the grouting pump 5; a mixing assembly is provided in the grout tank 3; the mixing assembly includes a mixing motor 7, a mixing shaft 8, and a mixing arm 9; a mixing shaft 8 is provided at the output end of the mixing motor 7, the mixing shaft 8 is vertically set at the center of the grout tank 3, the mixing arm 9 is set in the circumferential direction of the mixing shaft 8, a scraper 10 is provided at the end of the mixing arm 9, the far end of the scraper 10 is in contact with the inner wall of the grout tank 3; a bottom scraper 11 is provided on the mixing shaft 8 closest to the bottom of the grout tank 3, the lower edge of the bottom scraper 11 is in contact with the bottom of the tank.

[0034] To address the issue of residual slurry on the walls and bottom of the slurry tank, this invention includes a wall scraper 10 for removing residual slurry from the tank walls and a bottom scraper 11 for removing residual slurry from the bottom of the tank. This achieves deep cleaning of slurry in hard-to-reach areas such as the tank walls and bottom, thereby preventing slurry residue from causing clumping and potentially affecting subsequent grouting. Specifically, the stirring motor 7 is located on the outside of the slurry tank 3, specifically on the lower surface of the vehicle body 1. The stirring motor is connected to the stirring shaft 8 located inside the slurry tank via its output shaft. A stirring shaft 8 is installed inside the slurry tank 3. Stirring plates 9 are evenly installed on the outer surface of the stirring shaft 8. A scraper 10 is installed at the end of the stirring plate 9 away from the stirring shaft 8. A scraper 11 is installed on the outer surface of the bottom end of the stirring shaft 8. The scraper 10 and the scraper 11 are respectively attached to the side wall and bottom wall of the slurry tank 3. By setting up this structure of stirring motor 7, stirring shaft 8, stirring arm 9, scraper 10 and scraper 11, under the connection of the stirring shaft 8, the stirring motor 7 can drive the stirring plate 9, scraper 10 and scraper 11 to rotate simultaneously inside the slurry tank 3. On the one hand, it achieves the purpose of stirring. On the other hand, the scraper 10 and scraper 11 can carry out the slurry on the side wall and bottom wall of the slurry tank 3, improve the stirring effect, and prevent the slurry from remaining or even clumping.

[0035] In the specific implementation process, the number of scraper blades can be one for each mixing arm; that is, a scraper blade is placed at the end of the mixing arm, facing the tank wall. The outer edge of the scraper blade is in contact with the side wall of the slurry tank 3. As the scraper blade rotates with the mixing shaft and the mixing arm, the outer edge of the scraper blade scrapes the corresponding tank wall to remove residual slurry. In the specific implementation process, in order to further improve the scraping effect on the tank wall, a single scraper blade is placed at the end of the mixing arms in the same vertical column, with the outer edge of the scraper blade in contact with the side wall of the slurry tank 3. As the scraper blade rotates with the mixing shaft and the mixing arm, the outer edge of the entire scraper blade scrapes the corresponding tank wall, eliminating the problem of cleaning dead corners between adjacent scraper blades in the scenario where scraper blades are set separately. It should be noted that there should be a height difference between the bottom of the entire scraper blade and the bottom of the tank. Moreover, the outer edge of the scraper blade needs to be designed to conform to the curve of the tank wall.

[0036] In the specific implementation process, three groups of stirring arms can be set up, with each group of three stirring arms arranged symmetrically on the stirring shaft. The specific number of stirring arms can be 2-20, depending on the actual application scenario, and no specific limit is set here.

[0037] In one specific embodiment, to further improve the mixing efficiency of the mixing arm, the width of the mixing arm 9 is set according to the depth of the slurry in the slurry tank 3; the angle formed between the mixing arm 8 and the horizontal plane is 10° to 90°. That is, in specific implementations, the mixing arm can be a thin plate or a fan blade with a natural curvature, depending on the specific application scenario. For example, the mixing arm can be a paddle-shaped blade including an entry edge and a withdrawal edge, wherein the entry and withdrawal edges and the curvature of the cross-section of each mixing arm 8 are designed and manufactured using a natural equiangular spiral combination. During setup, the setting angle of the mixing arm can be 90°, meaning that the surface with the largest surface area of ​​the mixing arm 8 is vertically positioned in the slurry. When the mixing shaft 8 rotates, the mixing arm 9 is driven by the mixing shaft. A larger mixing arm angle enhances shear force and improves mixing efficiency; in scenarios where the slurry has good fluidity, the setting angle of the mixing arm can be appropriately reduced to reduce mixing resistance. For cement slurry, an angle of 60-85° for the mixing arm is optimal. The material of the stirring arm 8 is not particularly limited, as long as it possesses rigidity that will not deform or break due to liquid flow, and is harmless and has no impact on the slurry. However, it should be noted that the setting angle of all stirring arms should be consistent. The material of the stirring arm must have high strength and durability.

[0038] In one specific embodiment, a handrail 12 is provided on the other side of the pulp tank mounted on the vehicle body 1, with the height of the handrail being the same as the height of the pulp tank. That is, handrails 12 are symmetrically installed on the upper surface of the vehicle body 1, and are fixedly connected to the upper surface of the base 1 by bolts. The handrails 12, in conjunction with the wheels 2 located at the bottom of the vehicle body 1, facilitate the movement of the entire device. Furthermore, to further enhance the stability of the handrails 12, each handrail includes opposing support rods and a transverse beam positioned between the support rods. The two handrails are correspondingly positioned on both sides of the vehicle body. When the vehicle body needs to move, one person can stand on each side, and each person can push the vehicle body forward by holding the handrails on their respective sides.

[0039] In the specific implementation process, the grouting pump 5 and the grout tank 3 are connected by a connecting pipe 4; a control valve is installed on the upper surface of the connecting pipe 4, which can further control the discharge speed of the grout; in the specific implementation process, the grouting pipe is a reducing pipe with the pipe opening facing downwards. An extension plate is provided at the bend of the grouting pipe 6 to support the grouting pipe 6. Specifically, an extension plate 13 is installed on the vehicle body 1 near the grouting pipe 6, and the extension plate 13 is fitted onto the outer surface of the grouting pipe 6 to ensure the stability of the grouting pipe 6. In addition, a protective shell is provided on the outer cover of the mixing motor 7, and heat dissipation holes are provided on the protective shell. A protective shell is provided on the outer cover of the cleaning motor, and heat dissipation holes are provided on the protective shell. In other words, the protective shell 18 is set on the lower surface of the vehicle body 1 and is fitted on the outer surface of the stirring motor 7 (or cleaning motor). The outer surface of the protective shell 18 is evenly provided with ventilation holes. The protective shell 18 can provide protection for the stirring motor 7 (or cleaning motor), while the ventilation holes can further ensure heat dissipation.

[0040] Example 2

[0041] This utility model provides a grouting construction device, including a grout tank 3 for preparing cement grout, a vehicle body 1 for setting the grout tank 3, a grouting pump 5 for providing driving force for grouting, and a grouting pipe 6 provided at the output end of the grouting pump 5; a mixing assembly is provided in the grout tank 3; the mixing assembly includes a mixing motor 7, a mixing shaft 8, and a mixing arm 9; a mixing shaft 8 is provided at the output end of the mixing motor 7, the mixing shaft 8 is vertically arranged at the center of the grout tank 3, the mixing arm 9 is arranged in the circumferential direction of the mixing shaft 8, a scraper 10 is provided at the end of the mixing arm 9, and the far end of the scraper 10 is in contact with the inner wall of the grout tank 3; a bottom scraper 11 is provided on the mixing shaft 8 closest to the bottom of the grout tank 3, and the lower edge of the bottom scraper 11 is in contact with the bottom of the tank.

[0042] Besides the body and bottom of the grout tank, the inlet of the grouting pipe 6 is also a dead corner for grout residue. To further and promptly clean the inlet of the grouting pipe, an inlet cleaning assembly is installed on the vehicle body 1. This assembly includes a cleaning motor 14, a swing arm 15, and a protruding plate 16. The swing arm 15 is located at the output end of the cleaning motor 14, and the protruding plate 16 is located at the end of the swing arm 15, with its upper edge flush with the inlet of the grouting pipe 6. The protruding plate 16 can be an elastomer, or an elastomer for cleaning the grouting pipe inlet can be provided on the upper edge of the protruding plate 16. Specifically, the elastomer can be polyurethane (PU) or thermoplastic elastomer (TPE); for example, a polyurethane elastomer with excellent mechanical properties prepared using polytetrahydrofuran ether diol (PTMG-1000) and toluene diisocyanate (TDI-100) as raw materials. In other words, a cleaning motor is installed on the lower surface of the vehicle body near the grouting pipe. A swing arm is installed at the output end of the cleaning motor 14, and a protruding plate is installed on the upper surface of the swing arm. The protruding plate fits against the lower surface of the grouting pipe to achieve a cleaning effect on the grouting pipe. Specifically, in the actual implementation process, on the one hand, it can prevent residual grout from solidifying at the outlet of the grouting pipe 6 after grouting, ensuring the unobstructed flow of the grouting pipe 6; on the other hand, it can also hide and block the outlet of the grouting pipe 6 to ensure the subsequent normal use of the grouting pipe 6. Further, a preferred structure is that a shield 17 is provided between the cleaning motor 14 and the grouting pipe. Because the cleaning motor is located near the outlet of the grouting pipe, grout is easily splashed onto the cleaning motor during grouting and is difficult to clean; therefore, a shield 17 is installed on the lower surface of the vehicle body 1 to prevent grout splashing. The purpose of preventing grout splashing is achieved by the shield and / or the protective shell of the cleaning motor.

[0043] In summary, this utility model provides a grouting construction device. During use, the worker first holds the handrail 12 and, with the help of the wheels 2, pushes the grouting construction device to the grouting position. Then, the grouting pump 5 is turned on. At this time, the grouting pump 5 will draw the grout from inside the grout tank 3 through the connecting pipe 4 and inject it into the working position (e.g., the crack) through the grouting pipe 6. At the same time, the worker turns on the mixing motor 7 during grouting. Under the action of the mixing shaft 8, the mixing arm 9 drives the bottom scraper 11 and the wall scraper 10 to rotate together, thereby lifting the grout adhering to the inner wall of the grout tank 3 and the grout accumulated at the bottom of the grout tank 3, improving the mixing effect and preventing the grout from remaining or even clumping. After grouting is completed, the cleaning motor 14 can be turned on. The cleaning motor 14 will move the swing arm 15 and the convex plate 16 back and forth. The convex plate 16 will continuously rub against the outlet of the grouting pipe 6, thereby scraping off the residual material at the outlet of the grouting pipe 6, preventing the residual grout from solidifying at the outlet of the grouting pipe 6, and ensuring the unobstructed flow of the grouting pipe 6. Then, the motor is controlled to stop the swing arm 15 and the convex plate 16 directly below the grouting pipe 6, hiding the outlet of the grouting pipe 6, and ensuring the subsequent use of the grouting pipe 6.

[0044] However, those skilled in the art should understand that various improvements can be made to the grouting construction device provided by this utility model without departing from the scope of this utility model. Therefore, the scope of protection of this utility model should be determined by the content of the appended claims.
