[0033] like Figure 1 As shown, an embodiment of the present invention provides a wall crack repair device, including an adjustment frame 1, a telescopic rod 11 is installed on the top of the adjustment frame 1, and the telescopic rod 11 can adjust the height of the entire device by telescoping to achieve the repair of vertically arranged cracks. A plurality of rollers 12 are installed at the bottom of the adjustment frame 1, so that the adjustment frame 1 can translate relative to the wall. A swing block 2 is installed at the top of the telescopic rod 11 using a motor, and the swing block 2 is driven by the motor and can rotate around its own axis.

[0034] Combination Figure 2 Two rotating motors 21 are installed at the outer end of the swing block 2. The output end of the rotating motor 21 is hinged with an output rod 22, and the other end of the output rod 22 is connected to the grouting rod 3, so that the rotating motor 21 can drive the grouting rod 3 to rotate.

[0035] A plurality of grouting tubes 31 are arranged inside the grouting rod 3. A grouting plate 4 is arranged between the grouting rod 3 and the output rod 22. A liquid box 25 is arranged at the rear end of the grouting plate 4. The liquid box 25 is sleeved on the outside of the output rod 22. The grouting rod 3 is rotatably mounted on the grouting plate 4 and one end of the grouting tube 31 is connected to the liquid box 25. A grouting tube 5 is arranged on the side of the grouting plate 4 close to the swing block 2. One end of the grouting tube 5 is connected to the liquid box 25. The other end of the grouting tube 5 passes through the swing block 2 and is connected to an external liquid supply pump, and the liquid supply pump provides repair liquid for the equipment. The repair liquid is transported to the grouting tube 31 in the grouting rod 3 through the grouting tube 5 and the liquid box 25, and then transported to the bottom of the hole on the wall along the grouting tube 31 to repair the crack.

[0036] Combination Figure 3 and Figure 4A limit spring 65 is provided in the grouting pipe 31, and the axis of the limit spring 65 coincides with the axis of the grouting pipe 31. The end of the limit spring 65 away from the grouting plate 4 is connected to a plurality of flow regulating plates 6, and the plurality of flow regulating plates 6 are distributed in a circular array around the axis of the grouting pipe 31 in the grouting pipe 31. The repair liquid in the grouting pipe 31 pushes each flow regulating plate 6 to move in a direction away from the axis of the grouting pipe 31, thereby connecting the two ends of the grouting pipe 31.

[0037] An annular inner cavity 64 is provided in the grouting rod 3, and a plurality of pressing rods 62 are provided in the annular inner cavity 64 at intervals corresponding to each flow regulating piece 6. An opening and closing rod 61 is connected to the outer side of the flow regulating piece 6, and the other end of the opening and closing rod 61 is connected to one end of the inner side of the pressing rod 62. A return spring 63 is provided at a position corresponding to the opening and closing rod 61 on the outer side of the pressing rod 62, and the return spring 63 abuts against the wall of the annular inner cavity 64. Another return spring 63 is provided at the other end of the inner side of the pressing rod 62, and the other return spring 63 also abuts against the wall of the annular inner cavity 64.

[0038] When the flow regulating piece 6 is subjected to the pressure of the repairing liquid, the opening and closing rod 61 applies pressure to the pressing rod 62, and the end of the pressing rod 62 connected to the opening and closing rod 61 moves outward and compresses the corresponding reset spring 63. When the supply of the repairing liquid stops, the reset spring 63 corresponding to the opening and closing rod 61 extends, pushing the pressing rod 62 to reset, and multiple flow regulating pieces 6 gather to block the internal passage of the grouting pipe 31. At the same time, the reset spring 63 far away from the closing rod 61 plays a role in stabilizing the pressing rod 62 in this process, and the two reset springs 63 work together to assist the reset of the pressing rod 62.

[0039] Through the joint action of the flow regulating plate 6, the opening and closing rod 61, the pressing rod 62 and the two return springs 63, it can effectively prevent dust and debris in the holes on the wall from entering the grouting pipe 31 and causing blockage when the repair liquid is not injected, which can effectively reduce the occurrence rate of failures.

[0040] The surface of the grouting rod 3 is provided with a plurality of rhombus-shaped notches 32, and the cross-sectional area of ​​the rhombus-shaped notches 32 decreases as the distance between the grouting rod 3 and the grouting plate 4 increases. A plurality of inclined side tubes 311 are provided inside the grouting rod 3, and the plurality of side tubes 311 are distributed in a circular array around the axis of the grouting rod 3, and the two ends of the side tubes 311 are respectively connected to the grouting pipe 31 and the rhombus-shaped notches 32 on the surface of the grouting rod 3. A circular closed groove 33 is provided inside the grouting rod 3, and the closed groove 33 is located outside the grouting pipe 31, and the closed groove 33 is connected to each side tube 311.

[0041] Combination Figure 5 and Figure 6A plurality of closing blocks 46 are arranged in the closing groove 33, and the plurality of closing blocks 46 are distributed in a circular array around the axis of the grouting rod 3. A connecting block 47 is sleeved on the grouting plate 4, and the connecting block 47 is coaxially arranged with the driven gear 43. The closing block 46 is connected to the connecting block 47. When the grouting rod 3 rotates, the connecting block 47 and the closing block 46 will not rotate therewith.

[0042] The closing block 46 controls the connection or blocking of the side pipe 311 through the rotation of the grouting rod 3. Specifically, when the rotating motor 21 drives the grouting rod 3 to rotate, the positional relationship between the closing block 46 and the side pipe 311 can be changed. When the side pipe 311 rotates to the area corresponding to the closing block 46 in the closed groove 33, the side pipe 311 cannot connect the grouting pipe 31 and the diamond-shaped notch 32. When the side pipe 311 rotates to the area in the closed groove 33 that is staggered from the closing block 46, the side pipe 311 can connect the grouting pipe 31 and the diamond-shaped notch 32.

[0043] A circular coating groove 41 is provided at the front end of the coating plate 4, and a plurality of spray ports 411 in a circular array are provided at the bottom of the coating groove 41. The spray ports 411 are connected to the liquid box 25 through a pipeline, and the repair liquid in the liquid box 25 is sprayed out through the spray ports 411. A coating block 42 is provided in the coating groove 41, and the coating block 42 is circumferentially arranged around the axis of the grouting rod 3. A driven gear 43 is provided for internal rotation of the coating plate 4, and the coating block 42 passes through the coating groove 41 and is connected to the driven gear 43. When the driven gear 43 rotates, it can drive the coating block 42 to rotate. A rotating rack 44 is meshed on the outer side of the driven gear 43, and the inner side of the rotating rack 44 is connected to the output end power of two rotating motors 45.

[0044] When the rotary motor 45 rotates, the rotary rack 44 is driven to rotate, and the rotary rack 44 meshes with the two driven gears 43. The two driven gears 43 rotate with the rotation of the rotary rack 44, so the slurry coating block 42 connected to the two driven gears 43 rotates immediately. After the repair liquid is sprayed out from the spray port 411, the slurry coating block 42 rotates to evenly apply the repair liquid, so that the connection area between the grouting rod 3 and the slurry coating plate 4 can be evenly coated with the repair liquid.

[0045] The end of the rotary motor 45 away from the output end is hinged with a first connecting rod 23, and the other end of the first connecting rod 23 is hinged with a second connecting rod 24, and the other end of the second connecting rod 24 is hinged with the swing block 2. The first connecting rod 23 can be telescopic for length adjustment, and the first connecting rod 23 and the second connecting rod 24 control the positions of the grouting plate 4 and the grouting rod 3 by telescoping and swinging, respectively, so that the grouting plate 4 can swing relative to the grouting rod 3, so that when repairing the hole on the inclined wall, the grouting plate 4 can still be set parallel to the wall through the control of the first connecting rod 23 and the second connecting rod 24, so that the connection between the grouting rod 3 and the grouting plate 4 can still be sprayed with repairing liquid normally.

[0046] The embodiment of the present invention also provides a wall crack repair method, comprising:

[0047] Before starting the work, the flow regulating plates 6 are fitted together to close the grouting pipe 31 , and the closing block 46 blocks the two ends of the side pipe 311 .

[0048] According to the shape of the crack in the wall, after pre-drilling the crack in the wall, the grouting rod 3 is sent into the hole on the wall according to the inclination angle of the hole on the wall. After the grouting rod 3 enters the correct position, the grouting plate 4 is swung until it fits with the wall.

[0049] Afterwards, the spray port 411 sprays out the repair liquid, and the sprayed repair liquid will be confined in the area of ​​the slurry coating groove 41 when the slurry coating plate 4 is in contact with the wall surface. At the same time, the rotary motor 45 controls the slurry coating block 42 to rotate, and the slurry coating block 42 begins to apply the repair liquid sprayed out of the spray port 411 until the repair liquid is evenly distributed at the connection between the grouting rod 3 and the slurry coating plate 4. At this time, the grouting rod 3 rotates until the side tube 311 is moved out of the area where the closing block 46 is provided in the closing groove 33. At this time, the two ends of the side tube 311 are connected to each other.

[0050] After a certain period of waiting, the repair liquid at the connection between the grouting rod 3 and the grouting plate 4 solidifies, and then the repair liquid flows into the grouting pipe 31, and then flows out from the side pipe 311, and begins to spray the repair liquid on the cracks connected to the holes on the wall corresponding to the side of the grouting rod 3. The cracks on the sides of the holes on the wall can be repaired, and the repair liquid is sprayed directly into the cracks, which disturbs the connection between the holes and the cracks on the wall, and assists the repair liquid to enter the cracks smoothly.

[0051] Afterwards, the liquid supply pump increases the pressure, and the repair liquid applies pressure toward the flow regulating plate 6 through the grouting pipe 31, so that the flow regulating plates 6 are no longer fitted together, and the end of the grouting pipe 31 that penetrates into the hole on the wall can spray the repair liquid. The repair liquid sprayed from the end of the grouting pipe 31 that penetrates into the hole on the wall can spray the repair liquid to the cracks deep in the hole on the wall, thereby completely realizing the disturbance of debris and filling of repair liquid to the cracks at various positions.

[0052] After waiting for a while until the repairing liquid of the crack solidifies, the control device is moved as a whole in a direction away from the wall until the grouting rod 3 moves out of the hole on the wall, thereby completing the grouting repair of the wall crack.
