[0031] By providing the rolling ball 702 , the rotating tube 601 can stably rotate in the telescopic tube 600 , thereby driving the contact ball 602 to rotate, so that the contact ball 602 rolls in the crack of the road surface.

[0032] Further as Figure 2 As shown, fixed blocks 200 are fixed on both sides of the bottom surface of the base plate 100, and a threaded rod 201 is rotatably connected between the two fixed blocks 200 that are close to each other on one side. A servo motor 202 is fixed on one side of the bottom surface of the base plate 100, and the output end of the servo motor 202 is fixed to one end of the threaded rod 201. The movable frame 300 is movably connected to the outer side wall of the threaded rod 201. Engaging grooves 301 are respectively opened on both sides of the bottom surface of the base plate 100, and both sides of the top surface of the movable frame 300 correspond to and engage with the engaging grooves 301 respectively.

[0033] By means of the threaded rod 201 , the movable frame 300 can move on the bottom surface of the bottom plate 100 , thereby driving the rotating tube 601 to move.

[0034] Further as Figure 1 As shown, a top opening 502 is opened on the transverse central axis of the top surface of the base plate 100, a grouting pump 501 is fixed on one side of the transverse central axis of the top surface of the base plate 100, a storage bucket 102 is fixed on one side of the top surface of the base plate 100, the input end of the grouting pump 501 is through-connected with the outer wall of the storage bucket 102, the output end of the grouting pump 501 is connected with a grouting pipe 500, the grouting pipe 500 is located in the top opening 502, the grouting pipe 500 passes through the movable frame 300 and is connected with the top end of the telescopic tube 600.

[0035] Through the provided grouting pump 501 , the concrete slurry in the storage barrel 102 can be injected into the telescopic tube 600 , and then discharged from the opening of the contact ball 602 and injected into the cracks in the road surface.

[0036] The present solution has the following working process: when grouting is performed to repair the curved cracks in the road surface, the device is pushed to a suitable position, the universal wheel 101 is fixed, and then the telescopic tube 600 is moved by manually pulling the rotating tube 601, and the contact ball 602 is placed in the crack of the road surface, and the servo motor 202 is started, and the rotation of the servo motor 202 drives the threaded rod 201 to rotate, and the rotation of the threaded rod 201 drives the moving frame 300 to move, and the movement of the moving frame 300 drives the moving frame 400 to move, and the movement of the moving frame 400 drives the rotating tube 601 to move, thereby moving the contact ball 602, and when the contact ball 602 moves, it contacts the inner wall of the crack, so that the contact ball 602 moves. The contact ball 602 rolls on the inner wall of the crack. Since the crack is a curved extension, the contact ball 602 can push the movable frame 400 to move when rolling. The movable frame 400 moves the compressed spring 403. At the same time, the contact ball 602 moves, so that the contact ball 602 moves along the curved route in the crack. The grouting pump 501 is started. The grouting pump 501 injects the concrete slurry in the storage bucket 102 into the grouting pipe 500, and then into the telescopic pipe 600. Finally, it is injected into the crack from the opening of the contact ball 602 through the rotating pipe 601. As the telescopic pipe 600 moves, the concrete slurry is injected into the crack to complete the repair of the crack.

[0037] According to the above working process, it can be known that: by setting the telescopic tube 600, when grouting the crack, the telescopic tube 600 can be pulled so that the contact ball 602 is located in the crack, and by setting the rolling ball 702, the rotating tube 601 can stably rotate in the telescopic tube 600, thereby driving the contact ball 602 to rotate, so that the contact ball 602 rolls in the road crack, and by setting the contact ball 602, the contact ball 602 can roll on the inner wall of the crack, and by setting the spring 403, the movable frame 400 can move left and right on the positioning rod 401, so that the rotating tube 601 can stably inject concrete slurry into the crack along the direction of the crack, thereby avoiding the situation that when the pipe is used to move in the gap for grouting, the pipe is squeezed, causing the pipe to be unable to move in the crack and grouting cannot be done.

[0038] By providing the threaded rod 201 and the movable frame 300 , the rotating tube 601 can be moved in the crack, so that the rotating tube 601 can be moved in the crack and grouting can be performed, which saves manpower and improves the efficiency of crack repair.

[0044] By providing the universal wheels 101, the base plate 100 can be moved on the ground, and the entire device can be pushed to the position that needs to be repaired.

[0045] In summary: when grouting is performed to repair curved cracks in the road surface, the device is pushed to a suitable position, the universal wheel 101 is fixed, and then the rotating tube 601 is manually pulled to move the telescopic tube 600, and the contact ball 602 is placed in the road surface crack. By starting the servo motor 202, the servo motor 202 rotates to drive the threaded rod 201 to rotate, and the threaded rod 201 rotates to drive the moving frame 300 to move, and the moving frame 300 moves to drive the movable frame 400 to move, and the movable frame 400 moves to drive the rotating tube 601 to move, thereby moving the contact ball 602, and when the contact ball 602 moves, it contacts the inner wall of the crack, so that the contact ball 602 Rolling on the inner wall of the crack, since the crack is a curved extension, the contact ball 602 can push the movable frame 400 to move when rolling, and the movable frame 400 moves the compressed spring 403. At the same time, the contact ball 602 moves, so that the contact ball 602 moves along the curved route in the crack, and the grouting pump 501 is started. The grouting pump 501 injects the concrete slurry in the storage bucket 102 into the grouting pipe 500, and then into the telescopic pipe 600, and finally injects it into the crack from the opening of the contact ball 602 through the rotating pipe 601. As the telescopic pipe 600 moves, the concrete slurry is injected into the crack to complete the repair of the crack.

[0046] The servo motor 202 and the grouting pump 501 can be purchased on the market. They are mature technologies in this field and have been fully disclosed, so they are not repeated in the specification.
