Description

Technical Field

[0001] The utility model belongs to the technical field of concrete construction, and particularly relates to a grouting tool for repairing concrete cracks. Background Art

[0002] After the concrete structure solidifies, cracks are formed on the surface due to reasons such as ground subsidence. If these cracks are not repaired for a long time, they will gradually expand, affecting the stability and safety of the structure. The traditional repair method is to manually fill the cement slurry into the cracks, but this method has some problems. For example, it is impossible to effectively vibrate the concrete to reduce air bubbles, resulting in weak fixing force, and it can only fill to the surface and cannot penetrate to the bottom of the cracks.

[0003] The patent of "a grouting tool for repairing concrete cracks" with the publication number of "CN215803444U": It includes a fixed cylinder. One end of the fixed cylinder is provided with a discharge port, and a grouting pipe is arranged on the discharge port. A conveying component is arranged inside the fixed cylinder. The circumferential side of the end of the fixed cylinder far from the discharge port is provided with an injection pipe, and a concrete pipe is arranged on the injection pipe. The concrete pipe is connected to the injection pipe through a connecting component. Through the setting of the conveying component, the concrete entering the fixed cylinder can be quickly conveyed to the discharge port at the mouth of the fixed cylinder. And through the setting of the connecting component, the concrete pipe can be directly fixed on the injection pipe, without multiple concrete filling operations, which is very convenient and effectively improves a certain operation efficiency.

[0004] However, the above device still has deficiencies in the actual use process: Due to the large surface friction of the concrete structure, when the device is used, its stabilizing plate is closely attached to the ground and it is inconvenient to directly move on the concrete surface. To repair the entire crack, the device needs to be continuously lifted and moved, which is time-consuming and laborious, and the repair efficiency is low. Summary of the Utility Model

[0005] The purpose of the utility model is to solve the problem that when the existing device repairs cracks, the device needs to be continuously lifted and moved, resulting in a time-consuming and laborious repair process and low efficiency, and to propose a fast grouting tool for repairing concrete cracks.

The middle of the bottom ends of the two connecting rods is fixedly connected with a support shaft, and the support shaft is rotatably connected to the roller;

[0009] A rotating rod is rotatably connected to the inner top of the fixed cylinder. A spiral conveyor blade is fixedly connected to the surface of the rotating rod.

Specific embodiments

[0022] The technical solutions in the present utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] Refer to Figures 1-4 , a grouting tool for repairing concrete cracks, including a fixing cylinder 1, a connection component and a moving wheel 2. The inside of the fixing cylinder 1 is hollow. A stabilizing plate 3 is fixedly connected to the bottom of the fixing cylinder 1. The center of the bottom surface of the stabilizing plate 3 is fixedly connected with a discharge port 4. The discharge port 4, the stabilizing plate 3 and the fixing cylinder 1 penetrate and communicate with each other. Threads are provided on the outer surface of the discharge port 4. A grouting pipe 5 is threadedly connected to the outer surface of the discharge port 4. The grouting pipe 5 extends into the concrete crack for grouting operation. The moving wheel 2 is fixedly connected to the bottom surface of the stabilizing plate 3 near the circumferential edge;

[0024] The moving wheel 2 includes a fixing column 15, a rotating block 16 and a roller 18. The top end of the fixing column 15 is fixedly connected to the bottom surface of the stabilizing plate 3. The bottom end of the fixing column 15 is rotatably connected to the rotating block 16. Connecting rods 17 are fixedly connected to both sides of the bottom surface of the rotating block 16. A support shaft is fixedly connected to the middle of the bottom ends of the two connecting rods 17. The support shaft is rotatably connected to the roller 18. There are six moving wheels 2 and they are circumferentially arranged in an array on the bottom surface of the stabilizing plate 3. The total height of the moving wheels 2 is less than the length of the grouting pipe 5, so that the grouting pipe 5 can completely extend into the concrete crack. Limiting plates are fixedly connected to both the upper and lower surfaces of the fixing column 15 where the rotating block 16 is located, restricting the axial movement of the rotating block 16 on the fixing column 15. Positioning plates are fixedly connected to both sides of the roller 18 on the support shaft, restricting the axial movement of the roller 18 on the support shaft, making the entire moving wheel 2 more stable during movement;

[0025] By fixedly connecting moving wheels 2 to the bottom surface of the stabilizing plate 3, the moving wheels 2 are in direct contact with the concrete surface during equipment use. Thus, when repairing concrete cracks, the equipment can move along the concrete crack while repairing through the moving wheels 2, without lifting and moving the equipment, saving time and effort and having high repair efficiency.

[0026] At the inner top end of the fixed cylinder 1, a rotating rod 6 is rotatably connected. On the surface of the rotating rod 6, a spiral conveying sheet 7 is fixedly connected. At the center of the top surface of the fixed cylinder 1, a micro motor 8 is fixedly connected. The top end of the rotating rod 6 passes through the fixed cylinder 1 and is fixedly connected to the output shaft of the micro motor 8. On one side of the upper part of the fixed cylinder 1, an injection pipe 9 is communicated. The other end of the injection pipe 9 is communicated with a connection assembly. The other end of the connection assembly is communicated with a concrete pipe 13. At the top end and the lower part of the fixed cylinder 1, handles 14 are fixedly connected. Among them, the top handle 14 is arranged vertically and the lower part is arranged horizontally, which is convenient for construction workers to use the equipment.

[0027] The connection assembly includes a connection inner pipe 10, an elastic connection block 11 and a threaded connection ring 12. One end of the connection inner pipe 10 is communicated with the injection pipe 9. The elastic connection block 11 is fixedly sleeved on the outer surface of the connection inner pipe 10. Threads matching the threaded connection ring 12 are provided on the surface of the elastic connection block 11 and are threadedly sleeved with the threaded connection ring 12. The gap between the connection inner pipe 10 and the elastic connection block 11 is movably connected to the concrete pipe 13. By tightening the threaded connection ring 12, the concrete pipe 13 can be quickly fixed.

[0028] The functional principle of the present utility model can be elaborated through the following operation method:

[0029] During use, first, select a suitable grouting pipe 5 according to the depth of the crack to be repaired. Then, install the grouting pipe 5 on the discharge port 4 at the bottom end of the equipment. Next, sleeve the concrete pipe 13 on the connection inner pipe 10 and fix the concrete pipe 13 by tightening the threaded connection ring 12. When repairing the crack, insert the grouting pipe 5 into the crack. At this time, the moving wheels 2 fixedly connected to the bottom surface of the stabilizing plate 3 are in direct contact with the concrete surface. Turn on the micro motor 8 to drive the rotating rod 6 to rotate, so that the rotating rod 6 drives the spiral conveying sheet 7 thereon to rotate, convey the repair slurry entering the fixed cylinder 1 to the discharge port 4, and perform grouting operation on the crack through the grouting pipe 5.

[0030] Since the moving wheels 2 are in direct contact with the concrete surface during equipment use, the equipment can move along the concrete crack while repairing through the moving wheels 2 when repairing concrete cracks, without repeatedly lifting and moving the equipment, saving time and effort and having high repair efficiency.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
