Description

Technical Field

[0001] The present invention relates to the technical field of concrete crack repair, and in particular to an automatic concrete crack repair device and a use method thereof. Background Art

[0002] The construction method is to dig grooves along the cracks, and then fill the grooves with quick-setting cement. After the quick-setting cement hardens, it will have the effect of sealing the cracks. The main raw material of quick-setting cement is polyurethane. The disadvantages of using polyurethane for repair are: 1. Quick-setting cement is easy to shrink after hardening, forming a construction joint between the new and old concrete with the surrounding concrete, and new leakage channels are easy to form here; 2. Quick-setting cement is a rigid material and will not deform with the deformation of the structure. Once secondary cracks occur at the cracks, the sealing will fail; 3. If there is a steady flow of clear water and a certain water pressure, it is not suitable to use quick-setting cement directly for sealing.

[0003] Chinese patent CN207904991U discloses an underground engineering concrete crack repair structure, including a concrete structure and a crack, characterized in that: the crack is located in the concrete structure, the crack is filled with elastic polyurethane grouting liquid, a U-shaped water-based penetrating crystalline waterproof coating is arranged directly above the crack, the U-shaped water-based penetrating crystalline waterproof coating is filled with non-shrinkage quick-setting cement, the outer side of the U-shaped water-based penetrating crystalline waterproof coating and the non-shrinkage quick-setting cement is closely attached to the concrete structure with a horizontal water-based penetrating crystalline waterproof coating, and the width of the horizontal water-based penetrating crystalline waterproof coating is greater than the width of the U-shaped water-based penetrating crystalline waterproof coating.

[0004] Although the above improves the waterproof effect after the concrete cracks are repaired, it cannot be achieved for the repair of the side walls. This is because when the fluid is injected into the wall cracks, the fluid will overflow from the side walls under the action of gravity, which will cause the cracks on the side walls to be repaired. The material used for repair cannot fill the cracks. Summary of the invention

[0005] In view of the above problems, an automated concrete crack repair device and a method for using the same are provided.

[0043] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0044] Reference Figure 1-Figure 13: An automated concrete crack repair device comprises a frame 1, a repair device 2 and a moving device; the repair device 2 comprises an injection head, a scanner 21, a sealing cloth supply assembly 22, a fixing device 23 and a steering gear 24; the scanner 21 is arranged on one side of the frame 1; the injection head is arranged on the frame 1 on one side of the scanner 21, and the injection head is used to inject repair liquid into the crack; the sealing cloth supply assembly 22 is arranged on the side of the injection head away from the scanner 21, and the sealing cloth is stored in the sealing cloth supply assembly 22; the fixing device 23 is arranged on the side of the sealing cloth supply assembly 22 close to the injection head, and the fixing device 23 is used to cover and fix the sealing cloth supplied by the sealing cloth supply assembly 22 at the concrete crack; the steering gear 24 is arranged on the side wall of one side of the frame 1, and the steering gear 24 is used to drive the frame 1 to rotate, a controller is arranged in the frame 1, and the scanner 21 controls the operation of the steering gear 24 through the controller, and a lifting device is arranged at the lower part of the frame 1.

[0045] The lifting device is arranged on the upper part of the mobile device. When repairing the cracks on the side wall of the wall, the mobile device will fit the frame 1 with the side wall of the wall. At this time, the scanner 21 arranged on the frame 1 will scan the cracks on the wall and transmit the scanned crack pattern information to the processor. The processor draws a model of the crack according to the information transmitted back. When the processor determines that the direction of the crack is tilted, the steering gear 24 will drive the frame 1 to rotate, and the lifting device arranged at the lower part of the frame 1 will drive the frame 1 to rise, so that the injection head on the frame 1 can always be aligned with the crack. This is because when the direction of the crack is tilted, that is, when the direction of the crack is no longer horizontal, the crack will be tilted. The direction of the crack can be composed of a horizontal direction and a vertical direction. The moving device can control the horizontal direction, and the lifting device can control the vertical direction. At this time, the injection head will inject the repair liquid into the crack. Since the repair liquid itself has a certain viscosity, it will not flow out immediately after injection. The repair liquid is quick-setting cement. After the injection head fills the repair liquid into the crack, the fixing device 23 will cover the sealing cloth on the upper part of the crack. At the same time, the fixing device 23 will also fix the covering sealing cloth, so that the repair liquid after being injected will not flow out, so that when the equipment is repairing the side wall, it is guaranteed that the repair liquid will not leak out.

[0046] Reference Figure 1 , Figure 3 and Figure 4 : The sealing cloth supply assembly 22 includes a driving device 221 and a placement shaft 222; the driving device 221 is arranged on the frame 1 on the side of the injection head away from the scanner 21; the placement shaft 222 is rotatably arranged on the frame 1, and the sealing cloth is wound on the placement shaft 222. The driving device 221 is used to transport the sealing cloth on the placement shaft 222 to the fixing device 23.

[0047] Before use, the sealing cloth needs to be manually pulled to the fixing device 23. When in use, after the driving device 221 is started, the fixing device 23 will be driven to rotate by the driving device 221, and then the sealing cloth wrapped around the placement shaft 222 will be continuously brought out.

[0048] Reference Figure 1 , Figure 4 and Figure 5 : The driving device 221 includes a first rotating driver 2211, a first gear 2212 and a second gear 2213; the first rotating driver 2211 is horizontally arranged on the frame 1 on the injection head side away from the scanning side; the first gear 2212 is fixedly arranged on the output end of the first rotating driver 2211; the second gear 2213 is arranged on one side of the first gear 2212, the first gear 2212 and the second gear 2213 are meshed with each other, the second gear 2213 is fixedly connected to the fixing device 23, and the second gear 2213 can drive the fixing device 23 to operate.

[0049] The first rotary driver 2211 is preferably a servo motor. When the sealing cloth needs to be driven to output, the first rotary driver 2211 is started, and the first gear 2212 rotates under the drive of the first rotary driver 2211. Since the second gear 2213 and the first gear 2212 are meshed with each other, the second gear 2213 rotates.

[0050] Reference Figure 4 , Figure 7 , Fig. 9 and Fig.12 The fixing device 23 includes a nail supply assembly 231, a push device 232, a bracket 233, an annular frame 234, a protruding block 235 and a working groove 236; two annular frames 234 are provided, and the annular frames 234 are respectively fixedly arranged on both sides of the second gear 2213 along the axis of the second gear 2213; the bracket 233 is arranged in the annular frame 234, and the bracket 233 and the second gear 2213 are rotatably matched; the push device 232 is arranged on the bracket 233, and the push device 232 is used to accommodate nails; the nail supply assembly 231 is arranged on one side of the push device 232, and the nail supply assembly 231 is used to supply nails to the push device 232; a plurality of protruding blocks 235 are provided, and the plurality of protruding blocks 235 are evenly fixedly arranged on the inner wall of the annular frame 234 around the axis of the annular frame 234; the working groove 236 is opened through the side wall of the annular frame 234 opposite to the protruding block 235.

[0051] It is worth noting that when the second gear 2213 rotates, the bracket 233 will not rotate. When the first rotation driver 2211 is started, the second gear 2213 will rotate. Since the second gear 2213 is fixedly connected to the annular frame 234, the annular frame 234 will rotate together with the second gear 2213. When the second gear 2213 rotates, the bracket 233 will not rotate. In this way, the pushing device 232 arranged on the bracket 233 can be pushed by the protruding block 235. As the annular frame 234 rotates, the protruding block 235 arranged on the annular frame 234 will press the pushing device 232 downward. The pushing device 232 contains nails. At this time, the protruding block 235 will push the nails in the pushing device 232 out of the working groove 236, and the pushed out nails will penetrate the sealing cloth and fix the sealing cloth to the wall.

[0052] Reference Fig. 9 and Fig.10 The pushing device 232 includes an oil shell 2321, a pushing block 2322, a bellows 2323, an extension guide assembly, a pressing assembly and a first spring; the oil shell 2321 is fixedly arranged on the bracket 233, and hydraulic oil is arranged in the oil shell 2321; the pushing block 2322 is slidably arranged on the side wall of the oil shell 2321, and the protruding block 235 is used to push the pushing block 2322 to slide on the oil shell 2321, and there is a first gap between one end of the pushing block 2322 located outside the oil shell 2321 and the side wall of the oil shell 2321; The first spring is arranged in the first gap; an oil outlet is opened on the side of the oil shell 2321 away from the pushing block 2322, and the bellows 2323 is arranged on the oil outlet, and the cross-sectional area of ​​the bellows 2323 is smaller than the internal cross-sectional area of ​​the oil shell 2321; the pressing assembly is arranged on the end of the bellows 2323 away from the oil shell 2321; the extension guide assembly is arranged in the bellows 2323, and the two ends of the extension guide assembly are respectively fixedly connected to the pressing assembly and the oil shell 2321, and the extension guide assembly provides support for the bellows 2323.

[0053] When the pushing block 2322 is pushed by the protruding block 235, since the oil shell 2321 is fixed on the bracket 233 and the oil shell 2321 contains oil, the pushing block 2322 will push out the oil in the oil shell 2321, and the oil in the oil shell 2321 will flow into the bellows 2323. Since the cross-sectional area in the oil shell 2321 is larger than the cross-sectional area of ​​the bellows 2323, when the oil in the oil shell 2321 flows into the bellows 2323, the bellows 2323 will extend, and an extension guide assembly is provided in the bellows 2323, which guides the bellows 2323. Since one end of the extension guide assembly is fixedly connected to the pressing assembly, when the bellows 2323 extends, the pressing assembly will drive the nails thereon to extend, and the pressing assembly drives the nails to pass through the working groove 236 and penetrate the sealing cloth, thereby achieving the fixation of the sealing cloth. The first spring arranged between the first gap is compressed after the pushing block 2322 is pushed, and when the protruding block 235 leaves the pushing block 2322, the pushing block 2322 will be reset under the action of the first spring. At this time, the oil in the bellows 2323 is drawn back into the oil shell 2321, and the pressing assembly retracts automatically.

[0054] Reference Fig.11 The pressing assembly includes a pressing plate 2326, a guide rod 2327, a second spring 2328 and a placement rack 2329; the pressing plate 2326 is fixedly arranged on the end of the bellows 2323 away from the oil shell 2321; the guide rod 2327 is arranged on the pressing plate 2326 perpendicular to the upper part of the pressing plate 2326 and penetrates through the pressing plate 2326, and the guide rod 2327 is slidably matched with the pressing plate 2326; the placement rack 2329 is fixedly arranged at the bottom of the guide rod 2327; there is a second gap between the placement rack 2329 and the pressing plate 2326, and the second spring 2328 is arranged in the second gap.

[0055] When the oil in the oil shell 2321 is squeezed out, the pressing plate 2326 will move toward the working groove 236 on the opposite side of the protruding block 235 that pushes the pushing device 232 to operate under the guidance of the extended guide assembly. The placement rack 2329 is connected to the pressing plate 2326 through the guide rod 2327. In this way, after the pressing plate 2326 moves, the placement rack 2329 will also move accordingly, so that the nail will be pressed into the wall. The second spring 2328 is used to slow down the reaction force of the placement rack 2329 on the pressing plate 2326 when pressing the nail.

[0056] Reference Fig.10: The extension guide assembly includes an extension sleeve 2324 and an extension rod 2325; the extension sleeve 2324 is fixedly arranged inside the bellows 2323, and the extension sleeve 2324 is fixedly arranged at the bottom of the oil shell 2321 perpendicular to the bottom end surface of the oil shell 2321; the extension rod 2325 is slidably arranged in the extension sleeve 2324, and the end of the extension rod 2325 away from the extension sleeve 2324 is fixedly connected to the pressing assembly.

[0057] When the oil in the oil shell 2321 flows into the bellows 2323 , the bellows 2323 will expand and contract under the action of the oil. In order to ensure the stability of the bellows 2323 when extending, the extension sleeve will slide relative to the extension rod 2325 .

[0058] Reference Figure 3 and Figure 4 : The nail supply assembly 231 includes a supply tube 2311 and a storage box 2312; one end of the supply tube 2311 is connected to the pressing assembly, and the supply tube 2311 is used to guide the nails into the pressing assembly; the storage box 2312 is arranged at one end of the supply tube 2311 away from the pressing assembly.

[0059] When the device is running, the storage box 2312 supplies nails to the pressing assembly through the supply tube 2311.

[0060] Reference Figure 5 and Figure 6 : The automated repairing equipment also includes a cutting device 25, which includes a second rotary driver 251, a rolling wheel 252, a transmission belt 253 and a blade; the second rotary driver 251 is arranged on one side of the fixed component; a plurality of rolling wheels 252 are provided, and the plurality of rolling wheels 252 are arranged non-collinearly, and one of the rolling wheels 252 is fixedly connected to the output end of the second rotary driver 251; the transmission belt 253 is sleeved on the rolling wheel 252, and the transmission belt 253 cooperates with the rolling wheel 252 for transmission; the blade is fixedly arranged on the outside of the transmission belt 253.

[0061] When the scanner 21 scans the wall and finds that the gap on the wall has been repaired, the second rotary driver 251 will be started, and the second rotary driver 251 will drive the rolling wheel 252 to rotate, so that the transmission belt 253 will drive the blade thereon to cut the sealing cloth.
