Description

Technical field:

[0001] The utility model belongs to the field of concrete crack repair, in particular to a concrete crack grouting repair device. Background technology:

[0002] Concrete cracks are a common phenomenon, which is mainly due to the physical structural changes of the concrete structure caused by internal and external factors. These cracks not only affect the appearance of the concrete structure, but more importantly, they will reduce the bearing capacity, durability and waterproofness of the structure. The main methods for repairing concrete cracks include filling method, grouting method, structural reinforcement method, etc.

[0003] Taking the commonly used grouting method as an example, after the crack is repaired, the crack surface needs to be leveled to keep the repaired crack surface level with the plane where it is located and beautiful. In the prior art, after the crack grouting is completed, it is generally done manually with a handheld shovel or angle grinder to remove the solidified and raised excess part of the crack surface. This method is not only time-consuming and labor-intensive, but also has a low efficiency in leveling and repairing. Especially when using an angle grinder, the on-site operator will hold the angle grinder at an inclined angle for grinding. Since the grinding angle and force cannot always be kept consistent, the grinded crack is uneven, which affects the final effect of the crack repair. Utility model content:

[0004] The utility model aims to provide a concrete crack grouting repair device, and overcomes the shortcomings of the above-mentioned prior art, and effectively solves the existing problem of low efficiency in repairing crack surfaces.

[0005] The content of the utility model: A concrete crack grouting repair device includes a horizontal plate, legs are installed on the four corners of the horizontal plate, a dust reduction component is arranged on the top wall of the horizontal plate, a frame is installed on the bottom wall of the horizontal plate, a driving motor is installed vertically downward on the frame, a grinding wheel is installed on the rotating shaft of the driving motor, and the grinding wheel is used to grind the grouting of the ground cracks to make them smooth.

[0006] Furthermore, the dust reduction component includes a water tank, a water inlet is arranged on the top of the water tank, and a drip pipe is connected to the water tank, and the drip pipe is used to drop water onto the grinding wheel.

[0007] Furthermore, a valve is connected to the bottom wall of the water storage tank, the valve extends to below the bottom wall of the horizontal plate, and the top end of the drip pipe is connected to the valve.

[0008] Furthermore, the drip pipe is a telescopic hose.

[0009] Furthermore, the legs are installed at the four corners of the horizontal plate in an outwardly inclined manner.

[0010] Furthermore, a groove is provided at the bottom end of the supporting leg, and a roller is rotatably connected in the groove.

[0011] Furthermore, a reinforcing rib is horizontally installed between two adjacent legs.

[0012] The beneficial effects of the utility model are as follows: by moving the bracket composed of the horizontal plate and the supporting legs, the grinding wheel is moved parallel to the surface where the crack is located for grinding, and finally the protruding and solidified slurry on the crack surface is polished away smoothly, which not only saves time and labor, but also improves the efficiency of crack repair.

Specific implementation method:

[0017] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation of the present invention is now described with reference to the accompanying drawings:

[0018] like Figures 1 to 3 As shown, a concrete crack grouting repair device includes a horizontal plate 1, on the four corners of the horizontal plate 1 are installed supporting legs 2, the top wall of the horizontal plate 1 is provided with a dust reduction assembly, the bottom wall of the horizontal plate 1 is provided with a frame 3, a driving motor 4 is vertically downwardly installed on the frame 3, a grinding wheel 5 is installed on the rotating shaft of the driving motor 4, the grinding wheel 5 is used for grinding the ground cracks to make them smooth, the supporting legs 2 are obliquely installed outward on the four corners of the horizontal plate 1, a groove 10 is opened at the bottom end of the supporting legs 2, a roller 11 is rotatably connected in the groove 10, and a reinforcing rib 12 is horizontally installed between two adjacent supporting legs 2.

[0019] Specifically, by moving the bracket composed of the horizontal plate 1 and the supporting legs 2, the grinding wheel 5 moves parallel to the surface where the crack is located for grinding, and the protruding and solidified slurry on the crack surface is polished away evenly.

[0020] During actual use, after the crack grouting is completed, the repair device is placed on the surface where the crack is located, so that the bottom wall of the grinding wheel 5 fits with the surface where the crack is located. At this time, the drive motor 4 is started, and the roller 11 of the leg 2 is pushed to roll on the ground, so that the high-speed rotating grinding wheel 5 contacts the raised and solidified slurry on the crack surface and grinds it flat; the four legs 2 installed tilted outward make the repair device more stable when in use.

[0021] like Figures 1 to 3 As shown, a concrete crack grouting repair device, the dust reduction component includes a water tank 6, a water injection port 7 is arranged on the top of the water tank 6, a drip pipe 8 is connected to the water tank 6, the drip pipe 8 is used to drop water on the grinding wheel 5, a valve 9 is connected to the bottom wall of the water tank 6, the valve 9 extends to under the bottom wall of the horizontal plate 1, the top end of the drip pipe 8 is connected to the valve 9, and the drip pipe 8 is a telescopic hose.

[0022] Specifically, the dust generated during the grinding process can be reduced by the dust reduction component.

[0023] During actual use, the valve 9 can be opened to allow the water in the water tank 6 to flow into the drip pipe 8, and the drip pipe 8 can drop the water onto the grinding wheel 5 in the form of water drops or slow flow. This can not only cool the grinding wheel 5 to prevent equipment damage, but also the water accumulated on the grinding wheel 5 will gradually flow to the crack surface through its surface, thereby reducing the dust generated during the grinding process and protecting the environment from pollution and damage.
