Description

Technical Field

[0001] This invention belongs to the field of building construction technology, specifically an integrated device and construction method for locating and marking cracks in masonry structures. Background Technology

[0002] In the field of building construction, masonry structures are widely used in residential buildings, public buildings, and industrial plants due to their advantages such as readily available materials, simple construction techniques, and low cost. However, masonry structures are prone to cracking due to factors such as material shrinkage, temperature changes, foundation settlement, load effects, and construction quality. Therefore, it is necessary to locate and treat the surface of these cracks for repair.

[0003] According to publication number CN221350065U, entitled "A Wall Crack Detector," the device includes a support rod. A lifting rod is slidably connected to the upper end of the support rod, and a lifting screw is threadedly connected to the lower end of the lifting rod. The lower end of the lifting screw passes through the support rod and is fixedly connected to a first drive motor. Limiting strips are fixedly connected to the left and right inner walls of the support rod, and limiting grooves are provided at both ends of the lifting rod. A kit is fixedly fitted onto the outer wall of the support rod near the upper side. A fixing member is fixedly connected to the upper left side of the kit, and a detachable detector body is placed inside the fixing member. This invention eliminates the need for ladders or other tools when measuring high places, reducing labor and improving the efficiency of the workers. Activating the second drive motor allows the detector probe to move and rest against the wall. The structural design is more reasonable, ensuring the feasibility of this solution and freeing the user's hands, preventing arm fatigue and numbness. However, during the operation of the aforementioned device, the detector body is fixed inside the mounting bracket and adjacent to the masonry structure, which significantly limits the detector's detection range. When locating cracks, inspectors have to repeatedly adjust the device's position to try and cover more areas, which undoubtedly consumes a lot of time and makes the inspection process inefficient. This, in turn, reduces the crack detection efficiency. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated device for locating and marking cracks in masonry structures, comprising a telescopic rod and a mounting frame, and further comprising: A rotating mechanism is located inside the mounting bracket; The rotating mechanism includes a slider slidably connected inside the mounting bracket.

[0006] Preferably, the marking assembly includes a paint tank fixedly connected to one side of the mounting frame, an extraction assembly fixedly installed on one side of the paint tank, a nozzle fixedly installed on one side of the slider, and the extraction assembly and the nozzle connected to each other via a connecting pipe.

[0007] Preferably, it further includes: A cleaning mechanism is disposed inside the slider. The cleaning mechanism includes an airbag fixedly connected inside the slider. A pneumatic rod is fixedly installed inside the slider. The airbag and the pneumatic rod are connected through a connecting pipe. A fixed cylinder is fixedly installed at the top of the slider. A sealing block located inside the fixed cylinder is fixedly installed at the output end of the pneumatic rod. A support tube is fixedly installed at the top of the fixed cylinder. A nozzle located at the top of the positioning instrument body is fixedly installed at one end of the support tube. There are two airbags. A squeezing plate is fixedly installed at one end of each of the two airbags, and the squeezing plate is fixedly connected to a toothed ring.

[0008] Preferably, it further includes: A storage assembly is disposed at the bottom end of a telescopic rod. The storage assembly includes a fixed box fixedly connected to the bottom end of the telescopic rod. A fixed block is fixedly installed inside the fixed box. A threaded rod is slidably connected inside the fixed block. A limit ring is rotatably connected inside the bottom end of the fixed block. A gear three is fixedly installed at the bottom end of the limit ring, located on the surface of the threaded rod, and the threaded rod and gear three are threadedly connected. A motor two is fixedly installed on one side of the outer surface of the fixed block. A gear four that meshes with gear three is fixedly installed at the output end of the motor two. A mounting plate is fixedly installed at the bottom end of the threaded rod, and a roller is fixedly installed at the bottom end of the mounting plate.

[0009] Preferably, it further includes: A limiting component is disposed inside a fixed block. The limiting component includes a limiting rod disposed inside the fixed block. The limiting rod is slidably connected to a limiting block, and the limiting block is fixedly connected to a threaded rod.

[0010] Preferably, the fixed box has two square rods fixedly installed inside the mounting plate, and the two square rods are mirror images of each other.

[0011] Preferably, it further includes: A guide assembly is disposed inside the slider. The guide assembly includes a guide rod fixedly connected inside the slider. A guide ring is slidably connected to the surface of the guide rod, and one end of the guide ring is fixedly connected to a toothed ring.

[0012] Preferably, a limiting ring two located inside the slider is fixedly fitted on the surface of the top end of the gear one, and the surface of the limiting ring two is fully in contact with the inner wall of the slider.

[0013] Preferably, each of the support tubes is equipped with a one-way valve, and the surface of the sealing block is in contact with the inner wall of the fixed cylinder.

[0014] An integrated construction method for locating and marking cracks in masonry structures is as follows: S1: The operator pushes the device to one side of the masonry structure, then drives motor two to rotate gear four, which in turn drives gear three to rotate, which in turn drives limit ring one to rotate. Thus, limit ring one can limit gear three, and the threaded rod moves along the thread inside gear three. The threaded rod pulls the mounting plate and roller to retract into the telescopic rod, and the bottom of the fixed box will contact the ground. S2: Then, the operator drives the telescopic rod, which can cause the mounting frame to move upward. During the upward movement of the mounting frame, the slider and the positioning device body slide inside the mounting frame. The positioning device body has the function of capturing surface morphology using visible light. During the operation of the positioning device body, the drive motor one causes gear two to rotate. Gear two drives the gear ring and rack to move back and forth. The moving rack will drive gear one to rotate back and forth. Gear one is connected to the positioning device body, which in turn drives the positioning device body to rotate back and forth. S3: During the movement of the toothed ring, the movement of the toothed ring will drive the extrusion plate connected to it to move synchronously. When the extrusion plate moves, it will squeeze one of the air bladders. As the air bladder is squeezed, the gas stored inside is injected into the second connecting pipe. The gas enters the pneumatic rod through the channel of the second connecting pipe and drives its output shaft to push the sealing block to move inside the fixed cylinder. During the movement of the sealing block, the air inside the fixed cylinder is transported to the support pipe and finally sprayed out from the second nozzle. The sprayed gas can clean the positioning device body. S4: When a crack is detected, the locator body will accurately stop on one side of the crack to locate it. Then, the locator body moves along the direction of the crack, while the marking component is driven to mark the crack as the locator body moves, providing guidance for subsequent repair work.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention drives a first motor to rotate a second gear, which in turn drives a gear ring and a rack to reciprocate. The moving rack then drives the first gear to reciprocate, and the first gear is connected to the positioning instrument body, which in turn drives the positioning instrument body to reciprocate. Finally, the first motor drives the gear ring to drive the positioning instrument body to reciprocate, which increases the detection range of the positioning instrument body and allows it to capture surface morphology from different angles. This effectively avoids the problem of missed crack detection due to limited detection range and improves crack detection efficiency. This invention, during the movement of the toothed ring, a compression plate moves in tandem, compressing one of the air bladders. As the air bladder is compressed, the gas stored inside is injected into the pneumatic rod, which drives its output shaft to push the sealing block to move inside the fixed cylinder. During the movement of the sealing block, the air inside the fixed cylinder is transported to the support tube and finally ejected from the second nozzle. The ejected gas can clean the positioning device body. Ultimately, the toothed ring and the compression plate cause the gas inside the fixed cylinder to be ejected from the second nozzle, thereby cleaning the positioning device body and preventing dust around the masonry structure from adhering to the surface of the positioning device body, thus improving the positioning accuracy of the positioning device body. This invention drives a second motor to rotate a fourth gear, which in turn drives a third gear to rotate. The third gear then drives a first limiting ring to rotate, thus limiting the third gear. Consequently, the threaded rod moves along the internal thread of the third gear, pulling the mounting plate and rollers to retract into the telescopic rod. The bottom of the fixed box then contacts the ground, increasing the contact area between the device and the ground. Finally, the second motor drives the fourth gear to move the threaded rod, facilitating the retraction of the rollers and effectively preventing slippage during operation, thereby increasing the stability of the equipment.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figures 1 to 9 As shown, the present invention provides an integrated device for locating and marking cracks in masonry structures, including a telescopic rod 1 and a mounting frame 2, and further comprising: The rotating mechanism 3 is located inside the mounting bracket 2; The rotating mechanism 3 includes a slider 301 slidably connected inside the mounting bracket 2. A gear 302 is rotatably connected inside the slider 301. A positioning device body 303 located outside the slider 301 is fixedly installed at the top of the gear 302. A gear ring 304 is slidably connected inside the slider 301. A rack 307 is fixedly installed on the side of the gear ring 304 near the surface of the slider 301 and meshes with the slider 301. A motor 305 is fixedly installed at the top of the slider 301. A gear 306 located inside the gear ring 304 is fixedly installed at the output end of the motor 305. Marking component 4 is located on one side of mounting bracket 2.

[0020] The above solution involves an operator driving the telescopic rod 1 to move the mounting frame 2 upwards. During this upward movement, the slider 301 and the positioning device body 303 slide inside the mounting frame 2. The positioning device body 303 is equipped with the function of capturing surface morphology using visible light. When a crack is detected, the positioning device body 303 will precisely stop on one side of the crack to locate it. Subsequently, the positioning device body 303 moves along the direction of the crack, while the marking component 4 is driven to mark the crack as the positioning device body 303 moves, providing guidance for subsequent repair work. During normal operation of the mounting bracket 2, drive motor 305 drives gear 306 to rotate. Gear 306 is a half-gear design, meshing with the teeth on both sides of the gear ring 304. When gear 306 rotates, it drives the gear ring 304 to reciprocate. The reciprocating movement of the gear ring 304 drives the rack 307 connected to it to reciprocate as well. Since the rack 307 meshes with gear 302, the moving rack 307 drives gear 302 to reciprocate. Gear 302 is connected to the positioning instrument body 303, which in turn drives the positioning instrument body 303 to reciprocate. Finally, drive motor 305 drives the gear ring 304 to drive the positioning instrument body 303 to reciprocate, increasing the capture range of the positioning instrument body 303. This allows the positioning instrument body 303 to capture surface morphology from different angles, effectively avoiding the problem of missed crack detection due to limited capture range and improving crack capture efficiency.

[0021] like Figure 4 As shown, the marking component 4 includes a paint tank 401 fixedly connected to one side of the mounting bracket 2, an extraction component 402 fixedly installed on one side of the paint tank 401, and a nozzle 403 fixedly installed on one side of the slider 301. The extraction component 402 and the nozzle 403 are connected through a connecting pipe 404.

[0022] Using the above scheme: Through the design of the marking component 4, when the positioning instrument body 303 detects the crack and moves along the direction of the crack, the extraction component 402 can be driven to draw the paint from the paint tank 401 through the connecting pipe 404. Then the paint will pass through the connecting pipe 404 and be sprayed out from the nozzle 403. Since the nozzle 403 and the positioning instrument body 303 are on the same horizontal line, the paint can be sprayed towards the crack, thereby marking the crack.

[0023] like Figure 6 and Figure 7 As shown, it also includes: The cleaning mechanism 5 is located inside the slider 301. The cleaning mechanism 5 includes an airbag 501 fixedly connected inside the slider 301. A pneumatic rod 502 is fixedly installed inside the slider 301. The airbag 501 and the pneumatic rod 502 are connected through a connecting pipe 503. A fixed cylinder 504 is fixedly installed at the top of the slider 301. A sealing block 508 located inside the fixed cylinder 504 is fixedly installed at the output end of the pneumatic rod 502. A support tube 505 is fixedly installed at the top of the fixed cylinder 504. A nozzle 506 located at the top of the positioning instrument body 303 is fixedly installed at one end of the support tube 505. There are two airbags 501. A squeezing plate 507 is fixedly installed at one end of each airbag 501, and the squeezing plate 507 is fixedly connected to the toothed ring 304.

[0024] The above solution is adopted: Through the design of the cleaning mechanism 5, during the movement of the gear ring 304, the movement of the gear ring 304 will drive the connected extrusion plate 507 to move synchronously. When the extrusion plate 507 moves, it will exert a squeezing effect on one of the airbags 501. As the airbag 501 is continuously squeezed, the gas stored inside is injected into the connecting pipe 2 503. The gas enters the pneumatic rod 502 along the channel of the connecting pipe 2 503. The injection of gas provides power to the pneumatic rod 502, driving its output shaft to push the sealing block 508 in the fixed cylinder. During the movement of the sealing block 508, the air inside the fixed cylinder 504 is transported to the support pipe 505 and finally ejected from the nozzle 506. The ejected gas can clean the positioning instrument body 303. Finally, the gas inside the fixed cylinder 504 is ejected from the nozzle 506 through the linkage of the toothed ring 304 and the squeezing plate 507, thereby cleaning the positioning instrument body 303 and preventing dust around the masonry structure from adhering to the surface of the positioning instrument body 303, thus improving the positioning accuracy of the positioning instrument body 303.

[0025] like Figure 8 and Figure 9 As shown, it also includes: Storage component 6 is located at the bottom end of telescopic rod 1. Storage component 6 includes a fixed box 601 fixedly connected to the bottom end of telescopic rod 1. A fixed block 602 is fixedly installed inside the fixed box 601. A threaded rod 603 is slidably connected inside the fixed block 602. A limit ring 604 is rotatably connected inside the bottom end of the fixed block 602. A gear 605 located on the surface of the threaded rod 603 is fixedly installed at the bottom end of the limit ring 604. The threaded rod 603 and the gear 605 are threadedly connected. A motor 606 is fixedly installed on one side of the outer surface of the fixed block 602. A gear 607 that meshes with the gear 605 is fixedly installed at the output end of the motor 606. An mounting plate 608 is fixedly installed at the bottom end of the threaded rod 603. A roller 609 is fixedly installed at the bottom end of the mounting plate 608.

[0026] The above solution involves a storage component 6 that drives motor 2 606 to rotate gear 4 607. Since gear 4 607 meshes with gear 3 605, the rotating gear 4 607 drives gear 3 605 to rotate, which in turn drives limit ring 1 604 to rotate. Limit ring 1 604 then limits gear 3 605. Because gear 3 605 is threadedly connected to threaded rod 603, threaded rod 603 moves along the internal thread of gear 3 605. Threaded rod 603 pulls mounting plate 608 and roller 609 to retract into telescopic rod 1, and the bottom of fixed box 601 contacts the ground, increasing the contact area between the device and the ground. Finally, motor 2 606 drives gear 4 607 to move threaded rod 603, facilitating the retraction of roller 609 into its interior, effectively preventing slippage during operation and increasing the stability of the equipment.

[0027] like Figure 7 and Figure 8 As shown, it also includes: The limiting component 7 is disposed inside the fixing block 602. The limiting component 7 includes a limiting rod 701 opened inside the fixing block 602. The limiting rod 701 is slidably connected to the limiting block 702, and the limiting block 702 is fixedly connected to the threaded rod 603.

[0028] The above solution is adopted: through the design of the limiting component 7, when the threaded rod 603 moves, it will drive the limiting block 702 to slide inside the limiting rod 701, so that the limiting rod 701 can limit the limiting block 702, and the threaded rod 603 can slide smoothly inside the fixed block 602.

[0029] like Figure 9 As shown, two square rods 8 are fixedly installed inside the mounting plate 608 in the fixed box 601, and the two square rods 8 are mirror images of each other.

[0030] The above solution is adopted: by designing the square rod 8, the mounting plate 608 will slide on the surface of the square rod 8 when it moves. Since the square rod 8 is square, it can limit the position of the mounting plate 608 and prevent the position of the mounting plate 608 from shifting when it moves.

[0031] like Figure 4 and Figure 5 As shown, it also includes: The guide component 9 is disposed inside the slider 301. The guide component 9 includes a guide rod 901 fixedly connected inside the slider 301. A guide ring 902 is slidably connected to the surface of the guide rod 901, and one end of the guide ring 902 is fixedly connected to the toothed ring 304.

[0032] The above solution is adopted: through the design of the guide component 9, when the gear ring 304 moves, it will drive the guide ring 902 to slide on the surface of the guide rod 901. Then the guide rod 901 will guide the guide ring 902 and the gear ring 304 to move, so as to avoid the position of the gear ring 304 from shifting when it moves, and ensure that the gear ring 304 can stably drive the gear 302 to rotate.

[0033] like Figure 5 and Figure 7 As shown, a limiting ring 10 located inside the slider 301 is fixedly fitted on the top surface of the gear 302, and the surface of the limiting ring 10 is fully in contact with the inner wall of the slider 301. One-way valves are provided inside the support tube 505, and the surface of the sealing block 508 is in contact with the inner wall of the fixed cylinder 504.

[0034] The above scheme is adopted as follows: Through the design of the limiting ring 2 10, since the surface of the limiting ring 2 10 is fully in contact with the inner wall of the slider 301, when the gear 1 302 rotates, it will drive the limiting ring 2 10 to rotate, thereby limiting the gear 1 302. Through the design of the support tube 505, since the support tube 505 is equipped with a one-way valve, it can prevent gas from entering the other fixed cylinder 504, thereby ensuring that the gas will only be sprayed out from the nozzle 2 506. Furthermore, the surface of the sealing block 508 is in contact with the inner wall of the fixed cylinder 504, thereby facilitating the pushing of the air inside the fixed cylinder 504 into the support tube 505.

[0035] like Figures 1 to 9 As shown, an integrated construction method for locating and marking cracks in masonry structures is described, with the following control methods: S1: The operator pushes the device to one side of the masonry structure, and then drives the second motor 606 to rotate the fourth gear 607. The fourth gear 607 will drive the third gear 605 to rotate, and the third gear 605 will drive the first limiting ring 604 to rotate. Thus, the first limiting ring 604 can limit the third gear 605, and then the threaded rod 603 moves along the thread inside the third gear 605. The threaded rod 603 will pull the mounting plate 608 and the roller 609 to retract into the telescopic rod 1, and the bottom end of the fixed box 601 will contact the ground. S2: Then, the operator drives the telescopic rod 1, which causes the mounting frame 2 to move upward. During the upward movement of the mounting frame 2, the slider 301 and the positioning device body 303 slide inside the mounting frame 2. The positioning device body 303 has the function of capturing surface morphology with visible light. During the operation of the positioning device body 303, the drive motor 305 causes the gear 306 to rotate. The gear 306 drives the gear ring 304 and the rack 307 to move back and forth. The moving rack 307 drives the gear 302 to rotate back and forth. The gear 302 is connected to the positioning device body 303, thereby driving the positioning device body 303 to rotate back and forth. S3: During the movement of the toothed ring 304, the movement of the toothed ring 304 will drive the extrusion plate 507 connected to it to move synchronously. When the extrusion plate 507 moves, it will extrude one of the airbags 501. As the airbag 501 is extruded, the gas stored inside is injected into the connecting pipe 2 503. The gas enters the pneumatic rod 502 along the channel of the connecting pipe 2 503 and drives its output shaft to push the sealing block 508 to move inside the fixed cylinder 504. During the movement of the sealing block 508, the air inside the fixed cylinder 504 is transported to the support pipe 505 and finally sprayed out from the nozzle 2 506. The sprayed gas can clean the positioning device body 303. S4: When a crack is detected, the locator body 303 will accurately stop on one side of the crack to locate it. Then, the locator body 303 moves along the direction of the crack, while the marking component 4 is driven to mark the crack as the locator body 303 moves, providing guidance for subsequent repair work.

9. The integrated device for locating and marking cracks in masonry structures according to claim 3, characterized in that: Each of the support tubes (505) is equipped with a one-way valve, and the surface of the sealing block (508) is in contact with the inner wall of the fixed cylinder (504).

10. A construction method for integrated crack location marking in masonry structures, employing an integrated crack location marking device for masonry structures as described in any one of claims 1-9, characterized in that: The control method is as follows: S1: The operator pushes the device to one side of the masonry structure, and then drives motor two (606) to rotate gear four (607). Gear four (607) will drive gear three (605) to rotate. Gear three (605) will drive limit ring one (604) to rotate. Thus, limit ring one (604) can limit gear three (605). Then, threaded rod (603) moves along the thread inside gear three (605). Threaded rod (603) will pull mounting plate (608) and roller (609) to retract into telescopic rod (1). The bottom of fixed box (601) will contact the ground. S2: Then, the operator drives the telescopic rod (1), which can cause the mounting frame (2) to move upward. During the upward movement of the mounting frame (2), the slider (301) and the positioning instrument body (303) slide inside the mounting frame (2). The positioning instrument body (303) has the function of capturing surface morphology with visible light. During the operation of the positioning instrument body (303), the drive motor (305) causes the gear (306) to rotate. The gear (306) drives the gear ring (304) and the rack (307) to move back and forth. The moving rack (307) will drive the gear (302) to rotate back and forth. The gear (302) is connected to the positioning instrument body (303), which in turn drives the positioning instrument body (303) to rotate back and forth. S3: During the movement of the toothed ring (304), the movement of the toothed ring (304) will drive the extrusion plate (507) connected to it to move synchronously. When the extrusion plate (507) moves, it will squeeze one of the airbags (501). As the airbag (501) is squeezed, the gas stored inside is injected into the second connecting pipe (503). The gas enters the pneumatic rod (502) along the channel of the second connecting pipe (503) and drives its output shaft to push the sealing block (508) to move inside the fixed cylinder (504). During the movement of the sealing block (508), the air inside the fixed cylinder (504) is transported to the support pipe (505) and finally sprayed out from the nozzle (506). The sprayed gas can clean the positioning instrument body (303). S4: When a crack is detected, the locator body (303) will accurately stop on one side of the crack to locate the crack. Then, the locator body (303) moves along the direction of the crack, and the marking component (4) is driven to mark the crack as the locator body (303) moves, providing guidance for subsequent repair work.
