[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a self-healing and reinforcing grouting device for cracks, including a base frame 1, casters 2, a support frame 3, and a delivery pipe 4. Casters 2 are fixedly installed on both sides of the bottom of the base frame 1, and the support frame 3 is fixedly connected to the top of the base frame 1. The delivery pipe 4 is fixedly connected to the top of the support frame 3, and a mixing tank 5 is provided at the top of the delivery pipe 4. A mixing mechanism is provided at the top of the mixing tank 5. Repair concrete is poured into the interior of the mixing tank 5, and the mixing mechanism at the top of the mixing tank 5 continuously mixes the concrete. The mechanical force of the mixing continuously breaks down the initially formed crystalline structure of the concrete, keeping the concrete in a dynamic state of not being fully cured, thus preventing the concrete from solidifying inside the mixing tank 5. Then, the concrete is delivered to the crack through the delivery pipe 4 to fill and repair the crack.

[0019] The mixing mechanism includes a rotating shaft 6, mixing blades 7, stirring rods 8, a top frame 9, and a rotary motor 10. The top frame 9 is fixedly connected to the top of the mixing tank 5, and the rotary motor 10 is fixedly installed on the top of the top frame 9. The output end of the rotary motor 10 is fixedly connected to the rotating shaft 6, and the bottom end of the rotating shaft 6 is fixedly connected to the mixing blades 7. Multiple stirring rods 8 are fixed at equal intervals on the outer side of the mixing blades 7. One end of the stirring rods 8 is inclined upward. The mixing blades 7 and the stirring rods 8 are fixed to the bottom end of the rotating shaft 6, and the top end of the rotating shaft 6 is connected to the output end of the rotary motor 10 as a whole. The rotary motor 10 can drive the mixing blades 7 and the stirring rods 8 to rotate inside the mixing tank 5. The mixing blades 7 mix the concrete at the bottom of the mixing tank 5, while the stirring rods 8 mix the concrete at the top inside the mixing tank 5. The stirring rods 8 and the mixing blades 7 work together to mix the concrete inside the mixing tank 5 in all directions. The mechanical force of the mixing will continuously destroy the initially formed crystalline structure of the concrete, keeping the concrete in a dynamic state of not being fully cured, and preventing the concrete from solidifying inside the mixing tank 5.

[0020] One end of the delivery pipe 4 is provided with a clamp 17, and a hose 13 is fixedly connected to one end of the delivery pipe 4 through the clamp 17. One end of the hose 13 is provided with a grouting head 14. One end of the hose 13 is sleeved at the outlet of the delivery pipe 4, and the hose 13 is connected to the outlet of the delivery pipe 4 through the clamp 17. After the grouting head 14 is inserted into the crack, the concrete flows through the hose 13 to the grouting head 14, and the grouting head 14 directly delivers the concrete to the depth of the crack for repair.

[0021] The clamp 17 has an opening, and a threaded rod 19 is hinged to one side of the opening via a hinge seat 18. The other side of the opening has a groove 20. One end of the threaded rod 19 passes through the interior of the groove 20 and is threaded with a nut. After the hose 13 is fitted onto the outlet of the delivery pipe 4, the clamp 17 is fitted onto the outside of the hose 13. One end of the threaded rod 19 is rotated into the interior of the groove 20, and the nut is tightened at the end of the threaded rod 19 that passes through the groove 20. The nut causes the clamp 17 to retract inward, clamping the hose 13 and the outlet of the delivery pipe 4 to connect the hose 13 and the delivery pipe 4. To disassemble, simply loosen the nut, rotate the threaded rod 19 out of the groove 20, pull the clamp 17 away from the hose 13, and then pull the hose 13 out of the outlet of the filling head 14.

[0022] The conveying pipe 4 is rotatably connected to a screw 11. A drive motor 12 is fixedly installed at the end of the conveying pipe 4 away from the hose 13. The output end of the drive motor 12 passes through the interior of the conveying pipe 4 and is fixedly connected to one end of the screw 11. The output end of the drive motor 12 can drive the screw 11 to rotate inside the conveying pipe 4. The spiral blades on the outside of the screw 11 drive the concrete to flow towards the hose 13.

[0023] Both the rotary motor 10 and the drive motor 12 are provided with protective shells on their outer sides. Multiple anti-collision strips are provided on the outer side of the protective shells. The anti-collision strips are rectangular in shape. The protective shells and anti-collision strips can isolate the rotary motor 10 and the drive motor 12 from external objects, preventing external objects from directly contacting the rotary motor 10 and the drive motor 12, thus protecting the rotary motor 10 and the drive motor 12.

[0024] A push-pull rod 16 is fixedly connected to one side of the base frame 1. A rechargeable battery 15 is fixedly installed below the push-pull rod 16. The rechargeable battery 15 is electrically connected to the rotary motor 10 and the drive motor 12 through wires. The push-pull rod 16 can push the entire device to move. The rechargeable battery 15 can provide power to the rotary motor 10 and the drive motor 12. The rotary motor 10 and the drive motor 12 start working after receiving power.

[0025] The self-healing and reinforcing grouting device for cracks has a mixing blade 7 and a turning rod 8 fixed at the bottom of a rotating shaft 6. The top of the rotating shaft 6 is connected to the output end of a rotating motor 10. The rotating motor 10 can drive the mixing blade 7 and the turning rod 8 to rotate inside the mixing tank 5. The mixing blade 7 mixes the concrete at the bottom of the mixing tank 5, while the turning rod 8 mixes the concrete at the top inside the mixing tank 5. The turning rod 8 and the mixing blade 7 work together to mix the concrete inside the mixing tank 5 in all directions. The mechanical force of the mixing will continuously destroy the initially formed crystalline structure of the concrete, keeping the concrete in a dynamic state of not being fully cured, thus preventing the concrete from solidifying inside the mixing tank 5.
