Description

Technical Field

[0001] This invention relates to the field of crack detection technology, specifically a crack detection device for prefabricated building construction. Background Technology

[0002] In construction scenarios, cracks are a major manifestation of structural damage, with diverse causes including material shrinkage and deformation, temperature stress changes, external loads, and construction defects. They require timely detection and intervention through professional testing. Crack detection devices for prefabricated building construction are specialized equipment designed specifically for the unique process of "factory prefabrication, on-site assembly, node connection, and full-cycle operation and maintenance" in prefabricated buildings, building upon general-purpose devices. Compared to general-purpose detection devices for cast-in-place buildings, its core objectives are more targeted, focusing on solving three core problems unique to prefabricated buildings: first, quality control of prefabricated components before they leave the factory; second, defect identification at on-site assembly nodes; and third, dynamic risk warning throughout the entire construction cycle.

[0003] When conducting inspections on different surfaces, existing inspection instruments have two significant limitations: first, their functions are relatively limited, making it difficult to make targeted angle adjustments for different types of inspection surfaces and thus unable to flexibly meet diverse inspection needs; second, when inspecting at higher positions, relying on manual operation poses significant safety hazards and can easily lead to risks associated with working at heights. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides the following technical solution: a crack detection device for prefabricated building construction, comprising:

[0005] The base has a support column fixedly connected to its top, a flipping component slidably connected to the side of the support column, a drive component fixedly connected to the inner side of the base, a movable frame fixedly connected to the output end of the drive component, the top of the movable frame being fixedly connected to the flipping component, and rollers evenly arranged at the bottom of the base.

[0006] A detection component is used to detect the detection surface, and the side of the detection component is fixedly connected to the flipping component;

[0007] A cleaning component is used to clean the detection surface, and the bottom of the cleaning component is fixedly connected to the top of the flipping component;

[0008] The flipping component includes a support frame, the inner side of which is slidably connected to the side of the support column, a second driving component is fixedly connected to the side of the support frame, an adjustment mechanism is rotatably connected to the inner side of the support frame, the output end of the second driving component is fixedly connected to the side of the adjustment mechanism, and the top of the movable frame is fixedly connected to the side of the support frame.

[0009] The adjustment mechanism includes an adjustment frame, both sides of which are rotatably connected to the inner side of the support frame. The side of the adjustment frame is fixedly connected to the output end of the second drive component. An adjustment seat is rotatably connected to the inner side of the adjustment frame. An adjustment block is connected to the side of the adjustment frame via a threaded rod, and the side of the threaded rod is threadedly connected to the inner side of the adjustment block. A connecting block is fixedly connected to the top of the adjustment seat. The side of the adjustment seat away from the adjustment frame is fixedly connected to the side of the detector.

[0010] The detection component includes a detector, and buffer mechanisms are fixedly connected to both sides of the detector;

[0011] Preferably, the buffer mechanism includes a buffer seat, two buffer seats are symmetrically arranged on both sides of the detector, the side of the buffer seat is fixedly connected to the detector, the two sides of the inner wall of the buffer seat are slidably connected to a buffer rod, the other end of the buffer rod is fixedly connected to a buffer plate, the side of the buffer plate is slidably connected to the inner side of the buffer seat, the middle of the buffer plate is rotatably connected to a roller, a first spring is sleeved on the buffer rod, one end of the first spring is fixedly connected to the buffer plate, the other end of the first spring is fixedly connected to the inner side of the buffer seat, and a contact component is fixedly connected to the side of the buffer plate near the roller.

[0012] Preferably, the contact assembly includes a contact plate, both sides of which are fixedly connected to a buffer plate. The side of the contact plate is evenly provided with mounting grooves, and a roller is rotatably connected to the inner side of the mounting grooves. The side of the roller is evenly provided with grooves, and the side of the roller contacts the drum. This reduces the risk of impurities being brought into the detection area by the drum, avoids impurities adhering to the crack surface or interfering with the fit between the detection component and the detection surface, and indirectly improves the accuracy of measuring parameters such as crack width and depth. The cleaning process is carried out synchronously with the movement of the drum, ensuring the cleaning effect without affecting the detection efficiency, and adapting to the needs of continuous detection in building construction scenarios.

[0013] The cleaning component includes a cleaning shell, the bottom of which is fixedly connected to the top of a connecting block. A mesh plate is fixedly connected to the top of the cleaning shell. Moving wheels are rotatably connected to both sides of the top of the cleaning shell. An air suction machine is fixedly connected to the bottom of the inner cavity of the cleaning shell. A mesh plate is fixedly connected to the top of the air suction machine. A rotating mechanism is rotatably connected to the top of the mesh plate. A blocking mechanism is fixedly connected to the bottom of the mesh plate.

[0014] Preferably, the rotating mechanism includes a driving component three. The bottom of the driving component three is fixedly connected to the bottom of the inner cavity of the cleaning shell. A rotating shaft is fixedly connected to the output end of the driving component three. The side of the rotating shaft is rotatably connected to the inner side of the first and second mesh plates. A cleaning rod one is fixedly connected to both sides of the rotating shaft. A cleaning rod two is fixedly connected to both sides of the rotating shaft away from the cleaning rod one. The bottom of the cleaning rod two contacts the top of the first mesh plate. The cleaning rod two cleans the top of the first mesh plate simultaneously, which can promptly remove impurities that may accumulate in the pores of the first mesh plate, preventing the first mesh plate from becoming blocked. If the first mesh plate is blocked, the impurities swept off during cleaning will not be able to enter the cleaning shell smoothly, which will not only affect the impurity collection effect, but may also cause impurities to scatter again and contaminate the detection surface. The cleaning rod two ensures that the impurity collection channel is always unobstructed, improving the continuity of the cleaning work.

[0015] Preferably, the blocking mechanism includes a third mesh plate, with a structure in which the suction machine drives the third mesh plate downward to ensure that impurities can quickly enter the collection channel, avoiding the accumulation of impurities on the detection surface or the surface of the first mesh plate during the cleaning process, thus ensuring cleaning efficiency. The side of the third mesh plate is slidably connected to the inner side of the cleaning shell. The bottom of the third mesh plate is uniformly provided with blocking shafts, the top of the blocking shafts is fixedly connected to the bottom of the third mesh plate, and the bottom of the blocking shafts is slidably connected to the inner side of the second mesh plate. A second spring is sleeved on the blocking shaft, the top of the second spring is fixedly connected to the bottom of the third mesh plate, and the bottom of the second spring is fixedly connected to the top of the third mesh plate. A knocking component is fixedly connected to the inner side of the third mesh plate. The vibration of the knocking component can prevent impurities from clogging the third mesh plate, avoiding collection failure due to channel blockage, and further improving the thoroughness of impurity collection.

[0016] Preferably, the striking assembly includes a connecting sleeve, the side of which is fixedly connected to the inner side of the mesh plate one, a sliding shaft slidably connected to the inner side of the connecting sleeve, a sliding plate fixedly connected to the side of the sliding shaft, the side of the sliding plate slidably connected to the inner side of the connecting sleeve, a third spring sleeved on the sliding shaft, the top of the third spring fixedly connected to the bottom of the sliding plate, the bottom of the third spring fixedly connected to the bottom of the inner cavity of the connecting sleeve, striking shafts fixedly connected to both sides of the bottom of the sliding shaft, and a striking block fixedly connected to the other end of the striking shaft. After the mesh plate three is pulled down by suction, it abuts against the striking block in advance, avoiding the problem of empty striking caused by the gap between the two during striking, ensuring that the striking force can be transmitted to the mesh plate three, and the effect of shaking off the accumulated impurities is more thorough, reducing impurity residue.

[0017] This invention provides a crack detection device for prefabricated building construction. It has the following beneficial effects:

[0018] 1. The crack detection device for prefabricated building construction is equipped with a buffer mechanism. This design can prevent the accumulation of impurities from affecting the smoothness of the roller's rolling, and avoid impurities being brought into the detection area to contaminate the crack surface or interfere with the operation of the detection components, thereby further ensuring the stability of the detection process and the reliability of the detection results.

[0019] 2. This crack detection device for prefabricated building construction is equipped with a contact component to avoid the problem of rotation jamming caused by the accumulation of impurities on the roller surface, ensuring that the roller always rolls smoothly along the detection surface, ensuring the stability of the overall movement of the device, thereby maintaining the accuracy of the detection path and preventing the detection position from shifting due to roller jamming.

[0020] 3. This crack detection device for prefabricated building construction is equipped with a rotating mechanism. The cleaning rod directly acts on the detection surface to remove dust, debris and other impurities, clearing obstacles for subsequent crack detection and preventing impurities from obscuring cracks or interfering with the fit between the detector and the detection surface, thus ensuring the accuracy of the detection data.

[0021] 4. The crack detection device for prefabricated building construction is equipped with a blocking mechanism. After cleaning, the third mesh plate is reset by a spring to seal the first mesh plate. The staggered mesh design enhances the sealing effect and prevents the collected impurities from being scattered and contaminating the detection surface again.

[0022] 5. This crack detection device for prefabricated building construction is equipped with a tapping component. Through periodic tapping, it can promptly remove blockages and impurities from the three mesh openings of the mesh plate, ensuring that the impurity collection channel is always unobstructed. This avoids the accumulation of impurities on the detection surface or inside the cleaning shell due to mesh blockage, reducing the risk of secondary contamination of the detection surface and clearing obstacles for the accuracy of subsequent crack detection.

[0035] 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.

[0036] Example 1, please refer to Figures 1-2 This invention provides a technical solution: a crack detection device for prefabricated building construction, comprising:

[0037] The base 1 has a support column 2 fixedly connected to its top, a flipping component 4 slidably connected to the side of the support column 2, a drive component 8 fixedly connected to the inside of the base 1, a moving frame 3 fixedly connected to the output end of the drive component 8, the top of the moving frame 3 fixedly connected to the flipping component 4, and rollers 6 evenly arranged at the bottom of the base 1.

[0038] The detection component 5 is used to perform detection work on the detection surface. The side of the detection component 5 is fixedly connected to the flipping component 4.

[0039] Cleaning component 7 is used to clean the inspection surface. The bottom of the cleaning component 7 is fixedly connected to the top of the flipping component 4.

[0040] Please see Figure 3 The flipping component 4 includes a support frame 41, the inner side of the support frame 41 is slidably connected to the side of the support column 2, a driving component 42 is fixedly connected to the side of the support frame 41, an adjustment mechanism 43 is rotatably connected to the inner side of the support frame 41, the output end of the driving component 42 is fixedly connected to the side of the adjustment mechanism 43, and the top of the moving frame 3 is fixedly connected to the side of the support frame 41.

[0041] Before crack detection, drive component 2 42 needs to be activated. The output end of drive component 2 42 will drive adjustment mechanism 43 to rotate inside support frame 41. According to actual detection needs, such as detecting ground cracks, vertical cracks at construction sites, or top cracks at construction sites, the staff can make targeted adjustments through this rotation, so that detection component 5 and cleaning component 7 can be adapted to crack detection scenarios in different locations, ensuring that subsequent detection work can be carried out smoothly.

[0042] Please see Figure 4 The adjustment mechanism 43 includes an adjustment frame 431, both sides of which are rotatably connected to the inner side of the support frame 41. The side of the adjustment frame 431 is fixedly connected to the output end of the drive component 42. An adjustment seat 432 is rotatably connected to the inner side of the adjustment frame 431. An adjustment block 433 is connected to the side of the adjustment frame 431 through a threaded rod, and the side of the threaded rod is threadedly connected to the inner side of the adjustment block 433. A connecting block 434 is fixedly connected to the top of the adjustment seat 432. The side of the adjustment seat 432 away from the adjustment frame 431 is fixedly connected to the side of the detector 51.

[0043] Before the output end of the second drive component 42 drives the adjustment frame 431 to rotate and adjust inside the support frame 41, the adjustment block 433 needs to be rotated first. The adjustment block 433 will drive the adjustment seat 432 to complete the reverse adjustment and fix it inside the adjustment frame 431 through the screw rod, so that the adjustment seat 432 drives the cleaning component 7 to contact the crack to be detected through the connecting block 434, and the cleaning component 7 is started to clean the crack.

[0044] After cleaning is completed, rotate the adjusting block 433 again to make it drive the threaded rod to release the limit on the adjusting seat 432. Then rotate the adjusting seat 432 to adjust and fix it, so that the adjusting seat 432 can drive the detection component 5 to carry out the detection work on the cleaned cracks.

[0045] Please see Figure 5 The detection component 5 includes a detector 51, and buffer mechanisms 52 are fixedly connected to both sides of the detector 51.

[0046] When the detection component 5 detects cracks, the base 1 is first moved by the roller 6 so that the base 1 is fixed against the wall.

[0047] Subsequently, the detector 51 gradually approaches the crack under the action of the adjusting frame 431 and the support frame 41 until the buffer mechanisms 52 on both sides of the detector 51 are pressed tightly against the crack on the wall.

[0048] Finally, the roller 6 drives the base 1 to move smoothly, thereby enabling the detector 51 to continuously move and detect the crack. By emitting high-frequency sound waves and analyzing the echo time difference, the crack depth and internal defects can be measured.

[0049] Please see Figure 6 The buffer mechanism 52 includes a buffer seat 521. Two buffer seats 521 are symmetrically arranged on both sides of the detector 51. The side of the buffer seat 521 is fixedly connected to the detector 51. Buffer rods 522 are slidably connected to both sides of the inner wall of the buffer seat 521. Buffer plates 523 are fixedly connected to the other end of the buffer rods 522. The side of the buffer plate 523 is slidably connected to the inner side of the buffer seat 521. A roller 524 is rotatably connected to the middle of the buffer plate 523. A first spring 525 is sleeved on the buffer rod 522. One end of the first spring 525 is fixedly connected to the buffer plate 523. The other end of the first spring 525 is fixedly connected to the inner side of the buffer seat 521. A contact component 526 is fixedly connected to the side of the buffer plate 523 near the roller 524.

[0050] When the detector 51 detects the crack, the detector 51 first drives the buffer seats 521 on both sides to press against the crack on the detection surface, so that the roller 524 on the buffer seat 521 is in close contact with the detection surface.

[0051] When the base 1 moves the entire device via the rollers 6, the rollers 524 in the buffer seats 521 on both sides of the detector 51 will roll synchronously with the detection surface, ensuring that the detector 51 always keeps in close contact with the detection surface during the movement, avoiding measurement errors in crack width and depth due to loose contact or positional deviation, and ensuring the accuracy of basic detection data.

[0052] If the roller 524 rolls to an uneven area of ​​the detection surface, the roller 524 will be subjected to local squeezing force. At this time, the roller 524 will drive the buffer plate 523 to slide inside the buffer seat 521. At the same time, the buffer plate 523 squeezes the first spring 525 on both sides, and the buffer rod 522 will slide synchronously in the buffer seat 521 to buffer and guide, thereby offsetting the impact force brought by the uneven surface and preventing the detector 51 from shifting due to vibration. This not only protects the stability of the detection component 5, but also further reduces the interference of vibration on the detection accuracy.

[0053] In addition, during the rolling process of the roller 524 on the detection surface, it will continuously contact the contact component 526. The contact component 526 can clean the side of the roller 524 in real time and remove the dust and impurities attached to the surface of the roller 524 in a timely manner.

[0054] Please see Figure 7 The contact assembly 526 includes a contact plate 5621, both sides of which are fixedly connected to a buffer plate 523. The side of the contact plate 5621 is evenly provided with mounting grooves 5262. A roller 5263 is rotatably connected to the inner side of the mounting grooves 5262. The side of the roller 5263 is evenly provided with grooves 5264. The side of the roller 5263 is in contact with the roller 524.

[0055] As the roller 524 moves along the detection surface, the roller 524 will rotate synchronously with the movement of the device and maintain close contact with the detection surface.

[0056] To achieve real-time cleaning of the surface of the roller 524, multiple rollers 5263 are rotatably arranged in the mounting groove 5262 on the side of the contact plate 5621. These rollers 5263 will abut against the rotating roller 524 and rotate synchronously in the opposite direction as the roller 524 rotates. At the same time, grooves 5264 are evenly provided on the side of each roller 5263. When the roller 5263 contacts and rotates with the roller 524, the grooves 5264 can remove impurities adhering to the surface of the roller 524 from the detection surface through physical scraping.

[0057] Example 2, please refer to Figure 8 Based on Embodiment 1, the present invention provides a technical solution: the cleaning component 7 includes a cleaning shell 71, the bottom of the cleaning shell 71 is fixedly connected to the top of the connecting block 434, a mesh plate 73 is fixedly connected to the top of the cleaning shell 71, and movable wheels 72 are rotatably connected to both sides of the top of the cleaning shell 71. An air suction machine 74 is fixedly connected to the bottom of the inner cavity of the cleaning shell 71, a mesh plate 75 is fixedly connected to the top of the air suction machine 74, a rotating mechanism 77 is rotatably connected to the top of the mesh plate 73, and a blocking mechanism 76 is fixedly connected to the bottom of the mesh plate 73.

[0058] First, the rotating mechanism 77 is turned on, and the rotating mechanism 77 contacts the detection surface and completes the cleaning action. Then, the suction machine 74 at the bottom of the inner cavity of the cleaning housing 71 is started. The negative pressure suction generated by the suction machine 74 will drive the blocking mechanism 76 to move downward inside the cleaning housing 71, so that the blocking mechanism 76 is disengaged from the bottom of the screen plate 73. At this time, the impurities swept off the detection surface by the rotating mechanism 77 will enter the interior of the cleaning housing 71 through the screen plate 73 and finally be stored on the screen plate 75 for centralized collection, avoiding the situation where impurities fly around during the cleaning process.

[0059] Please see Figure 9 The rotating mechanism 77 includes a driving component 3 774. The bottom of the driving component 3 774 is fixedly connected to the bottom of the inner cavity of the cleaning housing 71. The output end of the driving component 3 774 is fixedly connected to a rotating shaft 771. The side of the rotating shaft 771 is rotatably connected to the inner side of the screen plate 1 73 and the screen plate 2 75. The two sides of the rotating shaft 771 are fixedly connected to a sweeping rod 1 772. The two sides of the rotating shaft 771 away from the sweeping rod 1 772 are fixedly connected to a sweeping rod 2 773. The bottom of the sweeping rod 2 773 is in contact with the top of the screen plate 1 73.

[0060] When cleaning the inspection surface, the drive component 3 774 must be activated first. The output end of the drive component 3 774 will drive the rotating shaft 771 to rotate. The rotating shaft 771 drives the cleaning rod 1 772 to rotate synchronously, so that the cleaning rod 1 772 can fully contact the inspection surface and complete the cleaning action to remove the impurities attached to the inspection surface. On the other hand, when the rotating shaft 771 rotates, it will also drive the cleaning rods 2 773 on both sides to rotate synchronously, so that the cleaning rods 2 773 can continuously contact the top of the screen plate 1 73 to clean the surface of the screen plate 1 73.

[0061] Please see Figure 10 The blocking mechanism 76 includes a mesh plate 3 761, the side of the mesh plate 3 761 is slidably connected to the inner side of the cleaning shell 71, the bottom of the mesh plate 3 761 is evenly provided with blocking shafts 762, the top of the blocking shafts 762 is fixedly connected to the bottom of the mesh plate 3 761, the bottom of the blocking shafts 762 is slidably connected to the inner side of the mesh plate 2 75, a second spring 763 is sleeved on the blocking shafts 762, the top of the second spring 763 is fixedly connected to the bottom of the mesh plate 3 761, the bottom of the second spring 763 is fixedly connected to the top of the mesh plate 3 761, and a striking component 764 is fixedly connected to the inner side of the mesh plate 3 761.

[0062] When cleaning the inspection surface, first start the suction machine 74. The negative pressure suction generated by its operation will drive the mesh plate 3 761 and the blocking shaft 762 to move downward, so that the mesh plate 3 761 is separated from the mesh plate 1 73.

[0063] During this process, the mesh plate 761 will simultaneously squeeze the blocking shaft 762 and the second spring 763 sleeved on the shaft, so that the spring is in a compressed state. At this time, the impurities that have been swept off the detection surface can smoothly enter the cleaning shell 71 through the holes of the mesh plate 73.

[0064] Meanwhile, during the process of cleaning the top of the screen plate 73 by the second cleaning rod 773, the bottom of the second cleaning rod 773 will be squeezed against the striking component 764.

[0065] This squeezing action triggers the tapping component 764 to tap the bottom of the screen plate 761. The vibration shakes off the impurities gathered on the surface of the screen plate 761, ensuring that the impurities can fall further through the pores of the screen plate 761 and finally gather on the screen plate 75 for centralized collection.

[0066] After the cleaning work is completed, the suction machine 74 is turned off, the negative pressure suction disappears, and the second spring 763, which is in a compressed state, will generate a restoring force, which will drive the mesh plate 761 to move upward through the abutment shaft 762 until the top of the mesh plate 761 is tightly attached to the bottom of the mesh plate 73. Since the mesh holes of the mesh plate 73 and the mesh plate 761 are designed to be staggered, after they are attached, the mesh plate 761 can completely block the gaps of the mesh plate 73, preventing the impurities collected in the cleaning shell 71 from sliding out through the mesh plate 73.

[0067] Please see Figure 11 The striking component 764 includes a connecting sleeve 7641, the side of which is fixedly connected to the inner side of the mesh plate 73, a sliding shaft 7642 slidably connected to the inner side of the connecting sleeve 7641, a sliding plate 7643 fixedly connected to the side of the sliding shaft 7642, the side of the sliding plate 7643 slidably connected to the inner side of the connecting sleeve 7641, a third spring 7646 sleeved on the sliding shaft 7642, the top of the third spring 7646 fixedly connected to the bottom of the sliding plate 7643, the bottom of the third spring 7646 fixedly connected to the bottom of the inner cavity of the connecting sleeve 7641, striking shafts 7644 fixedly connected to both sides of the bottom of the sliding shaft 7642, and a striking block 7645 fixedly connected to the other end of the striking shaft 7644.

[0068] When the suction machine 74 works and generates suction, the mesh plate 761 will move downward under the suction force and slide along the inside of the connecting sleeve 7641 until the bottom of the mesh plate 761 abuts against the top of the striking block 7645.

[0069] During the cleaning process of the second cleaning rod 773 cleaning the top of the first screen 73, the bottom of the second cleaning rod 773 will come into contact with the top of the sliding shaft 7642 and be squeezed.

[0070] Under this squeezing force, the sliding shaft 7642 will drive the slide plate 7643 to move downward inside the connecting sleeve 7641. At the same time, the sliding shaft 7642 will drive the two sides of the striking blocks 7645 to slide downward synchronously through the striking shaft 7644 below. During this process, the third spring 7646 sleeved on the sliding shaft 7642 will be stretched and store elastic potential energy.

[0071] When the second cleaning rod 773 rotates with the rotating shaft 771 and is no longer squeezed by the sliding shaft 7642, the third spring 7646 will release its elastic potential energy, causing the sliding shaft 7642 and the sliding plate 7643 to move upward and reset inside the connecting sleeve 7641.

[0072] During the reset process, the sliding shaft 7642 will drive the two side striking blocks 7645 to move upward through the striking shaft 7644, so that the striking blocks 7645 will strike the bottom of the previously contacted screen plate 3 761. Through this striking action, some of the impurities gathered on the surface or in the mesh of screen plate 3 761 can be shaken off, ensuring that the shaken-off impurities can pass smoothly through the mesh of screen plate 3 761 and finally fall onto screen plate 2 75 for centralized collection.

[0073] Specific workflow:

[0074] After the base 1 is moved to a suitable position by the rollers 6, the detection component 5 is adjusted by the flipping component 4 to align with the crack to be detected. If the detection height needs to be adjusted, the drive component 8 can be activated. Its output end will drive the flipping component 4 to move up and down along the four support columns 2 through the moving frame 3, thereby realizing the height adjustment of the detection component 5. In addition, before detecting the crack, the cleaning component 7 must be activated to clean the crack to remove attached impurities and dust, so as to avoid them interfering with the accuracy of the detection work.
