Description

Technical Field

[0001] This utility model relates to the field of grouting tools, specifically to a grouting tool for repairing concrete cracks. Background Technology

[0002] During construction and subsequent use, cracks may appear in concrete floors, transition zones, and construction joints. These cracks can be repaired using self-leveling compound, a highly fluid concrete repair material widely used to fill concrete cracks and uneven surfaces. When using it, the crack needs to be cleaned and moistened, the material mixed according to the instructions, poured into the crack, and allowed to flow and harden naturally. This method results in a more robust and durable repaired concrete surface that is easy to maintain, making it widely applicable for floor repair and surface leveling.

[0003] Self-leveling materials have good fluidity and low viscosity. When using them, buckets or ladles are often used to support or pour them, especially for narrow gaps. This can lead to inaccurate control and operator fatigue, resulting in significant errors during the pouring process. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] First embodiment:

[0026] See Figures 1-4 As shown, this utility model provides a concrete crack repair grouting tool, including a grout storage cylinder 1. The grout storage cylinder 1 has an open structure at the top and bottom, and its interior is provided with a cavity for grout delivery. The bottom end of the grout storage cylinder 1 is connected to a grouting nozzle 2, and the bottom of the grouting nozzle 2 has an opening. At the opening, a grouting core 3 is provided to control the delivery of grout from the grout storage cylinder 1. When the device is in use, grout can be delivered inside the grout storage cylinder 1. The grout storage cylinder 1 can be moved by a handheld device. When it is necessary to deliver the grout inside the grout storage cylinder 1, the grouting core 3 is aligned with the crack position to deliver the grout. Furthermore, the high end of the grout storage cylinder 1 is provided with a handle to facilitate the operation of the device by the handle 102. A feed hopper is installed at the top opening of the grout storage cylinder 1 to facilitate the delivery of grout into the grout storage cylinder 1. In another embodiment, the high end of the grout storage cylinder 1 is connected to a grout delivery device through a pipe. The grout delivery device can be a solenoid valve, a grout pump, or a grout cylinder. This configuration greatly improves the continuity of the device during use.

[0027] In addition, the grout storage cylinder 1 is threadedly connected to the grouting nozzle 2, and the outer wall of the grouting nozzle 2 is provided with a wrench groove, which can be used to assist in the rotational connection between the grout storage cylinder 1 and the grouting nozzle 2.

[0028] The second embodiment differs from the first embodiment in that:

[0029] The device also includes a support spring 4 that pushes the grouting core 3 toward the outer end of the grouting nozzle 2. The grouting core 3 includes a limiting boss 303, a sliding part 302, and a cone head 301 arranged sequentially from top to bottom. The limiting boss 303, the sliding part 302, and the cone head 301 are an integral structure. The grouting nozzle 2 is provided with a stepped hole 201. The small end of the stepped hole 201 is slidably engaged with the sliding part 302. The diameter of the limiting boss 303 is larger than that of the sliding part 302. There is an annular cavity between the limiting boss 303 and the inner diameter of the large end of the stepped hole 201 to assist in the guidance of grout. The movable end of the cone head 301 is provided with a lower guide hole 305. The inner end of the lower guide hole 305 extends into the interior of the sliding part 302. The side wall of the sliding part 302 is provided with an upper guide hole 304 that communicates with the lower guide hole 305. During device installation, the sliding part 302 is pushed from the inner end of the grouting nozzle 2. The slidable installation is located inside the stepped hole 201, and the cone head 301 protrudes from inside the stepped hole 201. The limiting boss 303 limits the sliding part 302, and the inner wall of the small end of the stepped hole 201 can prevent the slurry from entering the upper guide hole 304. Furthermore, when the cone head 301 is pressed down, the movable end of the cone head 301 can extend into the crack. As the device is pressed down, the grouting core 3 can overcome the elasticity of the support spring 4 and extend into the grouting nozzle 2. When the upper guide hole 304 extends into the inner diameter position of the large end of the stepped hole 201, the slurry can enter the upper guide hole 304 through the slurry storage cylinder 1 and the grouting nozzle 2, and be discharged through the lower guide hole 305. The device can realize the self-controlled discharge of slurry. When the device is in use, the slurry storage cylinder 1 can be in an inclined state so that the slurry can be discharged from the lower guide hole 305.

[0030] Furthermore, the inner end of the slurry storage cylinder 1 is provided with a limiting frame 101 for limiting the support spring 4. The limiting frame 101 is "T" shaped and can assist in the installation and limiting of the support spring 4. Furthermore, the limiting boss 303 is provided with a groove for limiting the support spring 4 on the side facing the support spring 4.

[0031] In addition, the upper guide hole 304 is inclined, with the lower end of the inclined surface facing the lower guide hole 305. The inclined upper guide hole 304 can assist in the flow of slurry. The outer circular surface of the limiting boss 303 is arc-shaped, which can improve the flow of slurry.

[0032] The third embodiment differs from the first embodiment in that:

[0033] A thrust frame 5 is provided on the outer side of the cone head 301. Specifically, the thrust frame 5 has a zigzag structure with its movable end extending downward. When the bottom end of the thrust frame 5 contacts the ground, the thrust frame 5 is positioned on both sides of the crack. By pressing the thrust frame 5, the grouting core 3 can be slid. This configuration allows for grouting operations in deeper cracks. In addition, a guide wheel is rotatably connected to the movable end of the thrust frame 5. The guide wheel can assist the device in moving, so that the grouting core 3 can be slid when pressed, thus achieving the flow of grout.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
