Description

Technical Field

[0001] This invention belongs to the field of concrete testing technology, and specifically relates to a device for detecting defects in reinforced concrete. Background Technology

[0002] Reinforced concrete refers to a composite building material in which steel bars or steel skeletons are pre-placed inside the concrete, and the two materials work together to bear the load after hardening. It is the core structural material of modern civil engineering. In the engineering and construction industry, reinforced concrete piles are a type of reinforced concrete. Reinforced concrete piles are usually prefabricated and need to be tested when they leave the factory.

[0003] In the current process of inspecting reinforced concrete piles, visual sensors are typically used to visually inspect the surface of the piles. However, only the front side can be inspected, so the piles need to be flipped over multiple times to complete the inspection. This multiple flipping process is inefficient. Furthermore, during the inspection of existing reinforced concrete piles, dust, demolding residue, and water impurities adhere to the outer wall of the pile, which can interfere with the clarity of CCD visual imaging and affect the accuracy of the inspection.

[0018] 4. Unlike existing technologies, this invention uses a downward detection mechanism to drive the support plate upward, simultaneously squeezing the soft oil bladder to supply oil. The coupling grease is evenly discharged through the silicone pad. After the oil is discharged, the downward detection mechanism drives the support plate downward, allowing the silicone pad to adhere to the curved surface of the pile foundation. This ensures uniform coupling without air bubbles, improves the stability of ultrasonic wave transmission, reduces the amount of manual oiling, and provides strong controllability. The silicone pad is assembled with a snap-fit ​​design, making it easy to install and remove. It also allows for easy replacement of different silicone pads according to the size of the reinforced concrete pile, making it highly adaptable. Attached Figure Description

It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example: Please refer to Figure 1 and Figure 2A reinforced concrete defect detection device includes a base plate 1, which is a single piece of steel bearing base, serving to bear the weight and position all components of the device. A rotary conveying mechanism 2 is installed on the top of the base plate 1 for rotating and transporting the reinforced concrete piles. The rotary conveying mechanism 2 can drive the cylindrical reinforced concrete piles to rotate synchronously and move axially forward, cooperating with the detection station to complete continuous detection operations, achieving uniform circumferential detection. A fixed arm 3 is fixedly installed on the rear side of the base plate 1, and a downward detection mechanism 4 is installed on the fixed arm 3 for detecting the interior of the reinforced concrete piles. The downward detection mechanism 4 performs non-destructive testing on defects such as voids, segregation, and steel corrosion inside the reinforced concrete piles. A gantry frame 5 is fixedly installed on the right side of the base plate 1, and a gantry frame is installed on the gantry frame 5 for inspecting the reinforced concrete piles. A CCD vision camera 6 is used for surface inspection. The CCD vision camera 6 is used to image and detect surface defects such as cracks, peeling, and honeycomb pitting on the reinforced concrete pile. A cleaning mechanism 7 is jointly provided on the base plate 1 and the rotary conveying mechanism 2. The cleaning mechanism 7 can automatically clean the floating dust and demolding concrete residue attached to the outer wall of the pile before pile inspection, so as to avoid impurities affecting the accuracy of visual imaging and ultrasonic inspection. A guide mechanism 8 is provided on the right side of the cleaning mechanism 7. The guide mechanism 8 is used to support and guide the reinforced concrete pile. A feeding mechanism (not shown in the figure) is provided on the right side of the guide mechanism 8.

[0023] Please see Figure 1 and Figure 3 The guiding mechanism 8 includes two support legs 81 located on the right side of the base plate 1. The support legs 81 raise the bearing height to adapt to the pile conveying height. An I-beam 82 is fixedly installed on the top of the two support legs 81. Arc-shaped mounting plates 83 are fixedly installed at both the front and rear ends of the top of the I-beam 82. Arc-shaped grooves 84 are opened on the arc-shaped mounting plates 83, which are arc-shaped adjustment stroke grooves. Two side plates 88 are symmetrically installed in the middle of the top of the I-beam 82. A bottom support roller 86 is rotatably connected between the two side plates 88. Fixed seats 87 are installed on both the front and rear sides of the bottom support roller 86. Side clamping rollers 85 are rotatably installed on the fixed seats 87. A screw is rotatably installed at the top center of the side clamping rollers 85. The screw slides through the arc-shaped groove 84 and is threaded to a nut. An anti-slip pad is provided between the nut and the arc-shaped mounting plate 83. The anti-slip pad increases the friction and prevents the screw from slipping after locking.

[0024] In use, when it is necessary to adjust the angle of the side clamping roller 85 according to the diameter of the reinforced concrete pile, loosen the nut and loosen the anti-slip pad to press and fix the arc mounting plate 83. At this time, slide the screw along the arc groove 84, and simultaneously drive the side clamping roller 85 to slide along the arc groove 84. When the side clamping roller 85 is adjusted to a suitable angle, tighten the nut to fix the side clamping roller 85. After the reinforced concrete pile is fed by the feeding mechanism, it is supported and limited by the guide mechanism 8, and then enters the cleaning mechanism 7.

[0025] Please see Figure 4 , Figure 5 and Figure 6 The rotary conveying mechanism 2 includes several bearing seats 10 symmetrically fixedly installed on the top of the base plate 1. The bearing seats 10 are arranged in pairs and symmetrically distributed. A spiral conveying roller 21 is rotatably installed between the two bearing seats 10 in the same group. The outer wall of the spiral conveying roller 21 is provided with spiral protrusions. The spiral texture friction drives the foundation pile to rotate and feed material axially. A synchronization component 22 is provided on the right side of the spiral conveying roller 21. A transmission component 26 is provided on the right side of the synchronization component 22. The synchronization component 22 includes a fixed shaft 23 fixedly installed on the right side of the spiral conveying roller 21. The fixed shaft 23 rotatably passes through the bearing seat 10 on the right side. A first transmission shaft 25 is rotatably installed at the bottom of the bearing seat 10 on the right side. The first transmission shaft 25 and the fixed shaft 23 are connected by the synchronization component 22. The synchronization component 22 consists of a synchronization wheel and a synchronization belt. The synchronization component 22 is the prior art. A first bevel gear 24 is fixedly sleeved on the right end of the first transmission shaft 25.

[0026] Please see Figure 4 , Figure 5 and Figure 6 The transmission assembly 26 includes two mounting seats 262 fixedly installed on the top of the base plate 1. A synchronous shaft 263 is rotatably passed through each of the two mounting seats 262. A third bevel gear 264 is fixedly installed at one end of the synchronous shaft 263, and a second bevel gear 261 that meshes with the first bevel gear 24 is fixedly sleeved at the other end of the synchronous shaft 263, converting horizontal power into vertical power and driving the first transmission shaft 25 to rotate.

[0027] Please see Figure 2 , Figure 4 and Figure 7The cleaning mechanism 7 includes two fixed plates 75 fixedly installed on the top of the base plate 1. A cleaning component 71 is provided on the top of the fixed plate 75. A power component 74 is provided on the fixed plate 75. The power component 74 includes a servo motor 741 fixedly installed on the right fixed plate 75. The servo motor 741 is the only linkage drive source of the whole machine. The speed is adjustable to adapt to different cleaning and feeding speeds. The output end of the servo motor 741 rotates through the fixed plate 75 and is fixedly installed with a second drive shaft 742. A drive spur gear 744 is fixedly sleeved in the middle of the second drive shaft 742. The drive spur gear 744 is located between the two fixed plates 75. The output end of the second drive shaft 742 rotates through the left fixed plate 75 and is fixedly sleeved with a fourth bevel gear 743 that meshes with a third bevel gear 264.

[0028] Please see Figure 4 , Figure 7 and Figure 8 The cleaning assembly 71 includes a limiting ring 712 rotatably connected to a fixed plate 75. A rotating ring 711 is fixedly installed between the two limiting rings 712. The rotating ring 711 is an annular bearing base that carries cleaning and guiding components. A toothed ring 72 that meshes with a drive spur gear 744 is fixedly sleeved on the outside of the rotating ring 711. Several cleaning brushes 714 and guide plates 713 are evenly fixedly installed on the inner wall of the rotating ring 711. The guide plate 713 is located between two adjacent cleaning brushes 714. A retaining ring 715 is fixedly installed on the left side inside the rotating ring 711. A guide groove 73 is fixedly installed on the right side of the fixed plate 75. The guide plate 713 is installed at an angle. The angled guide plate 713 is used to guide the cleaned impurities and debris into the guide groove 73, which facilitates the collection of dust and impurities.

[0029] In use, the servo motor 741 is started, and the output of the servo motor 741 drives the second transmission shaft 742 to rotate, which in turn drives the active spur gear 744 to rotate. At the same time, the gear ring 72 and the rotating ring 711 on it rotate, which in turn drives the cleaning brush 714 to rotate. The cleaning brush 714 is used to clean the outer wall of the reinforced concrete pile. During the rotation, debris and impurities fall from the cleaning brush 714 and are guided by the guide plate 713 into the guide groove 73. After being guided by the guide groove 73, they enter the collection box for collection, which facilitates the cleaning of the surface of the reinforced concrete pile. While rotating and cleaning, the fourth bevel gear 743 is driven to rotate, which in turn drives the third bevel gear 264 and the synchronous shaft 263 on it to rotate, which in turn drives the second bevel gear 261 to rotate. The synchronous component 22 drives the fixed shaft 23 to rotate, which in turn drives the two spiral conveying rollers 21 to rotate in opposite directions. The compression of the spiral conveying rollers 21 drives the reinforced concrete pile to rotate and be conveyed forward.

[0030] Please see Figure 1 , Figure 9 and Figure 10The pressure detection mechanism 4 includes a telescopic cylinder 41 fixedly installed on the top of the fixed arm 3. The output end of the telescopic cylinder 41 moves through the fixed arm 3 and is fixedly mounted on a support plate 42. An ultrasonic sensor probe 45 is installed at the bottom of the support plate 42. The ultrasonic sensor probe 45 is connected to an ultrasonic instrument via a data cable. Both the ultrasonic sensor probe 45 and the ultrasonic instrument are existing technologies. A soft oil bladder 43 is fixedly installed on the top of the support plate 42. The soft oil bladder 43 is made of elastic rubber, is U-shaped, and can deform and contract under pressure and rebound to its original position after pressure is released. A one-way oil inlet valve is installed on the side wall of the soft oil bladder 43, which is connected to an oil pump. The oil pump automatically replenishes the soft oil bladder 43 and can block... The coupling grease flows back in the reverse direction. Two delivery pipes 46 are fixedly connected to the soft oil bladder 43. The ends of the two delivery pipes 46 away from the soft oil bladder 43 are fixedly connected to a silicone pad 44. The silicone pad 44 is hollow inside and has an arc-shaped bottom. The arc-shaped surface is adapted to fit the outer wall of the circular foundation pile, and several oil outlet holes are evenly opened on the arc-shaped surface. The oil outlet holes are connected to the internal cavity of the silicone pad 44. The soft oil bladder 43 stores coupling grease. A rubber sleeve 47 is fixedly installed on the top of the silicone pad 44. A slot is opened inside the rubber sleeve 47. An annular locking block that engages with the slot is fixedly installed on the bottom outer wall of the ultrasonic sensing probe 45. The bottom of the ultrasonic sensing probe 45 is in contact with the top of the silicone pad 44.

[0031] During use, during the rotating conveying and feeding of reinforced concrete piles, a CCD vision camera 6 is used to uniformly photograph the outer surface of the reinforced concrete piles circumferentially, taking multiple photos. These photos are transmitted to the background system for automatic detection and judgment. After visual inspection, when the front, middle, and rear ends of the reinforced concrete piles are conveyed directly below the pressing detection mechanism 4, the conveying of the reinforced concrete piles is stopped, and the telescopic cylinder 41 is activated. The output end of the telescopic cylinder 41 retracts, driving the support plate 42 and the soft oil bladder 43 on it to move upward. The soft oil bladder 43 presses against the top wall of the fixed arm 3. At this time, the coupling grease stored in the soft oil bladder 43 enters through the conveying pipe 46. The grease is inserted into the silicone pad 44 and then squeezed out from the oil hole. At this time, the output end of the telescopic cylinder 41 moves down, driving the support plate 42 and the ultrasonic sensor probe 45 on it to move downward, and simultaneously driving the silicone pad 44 to move downward until the silicone pad 44 is tightly attached to the top of the reinforced concrete pile. The coupling grease fills the gap between the reinforced concrete pile and the silicone pad 44, ensuring uniform coupling without air bubbles, improving the stability of ultrasonic wave transmission, reducing the amount of manual oiling work, and providing strong controllability. Subsequently, the ultrasonic sensor probe 45 and ultrasonic instrument are used to detect the inside of the reinforced concrete pile, and the CCD vision camera 6 is used to detect the outside of the reinforced concrete pile, realizing both internal and external detection at the same time.

[0032] Please see Figure 2 and Figure 11The scraping mechanism 9 includes a support frame 91 fixedly installed on the top front side of the base plate 1. A threaded rod 92 is threaded through the top of the support frame 91. A handwheel 95 is fixedly installed on the front side of the threaded rod 92. A limit plate 93 is fixedly installed on the top of the threaded rod 92. A guide rod 94 slides through the limit plate 93. A plug-in rail 97 is rotatably installed on the rear side of the threaded rod 92. The top front side of the plug-in rail 97 is fixedly connected to the rear side of the guide rod 94. A scraping plate 96 is slidably plugged into the plug-in rail 97. The rear side of the scraping plate 96 is an arc-shaped surface that fits against the outer wall of the reinforced concrete foundation pile. A connecting rod is fixedly installed at the bottom of the plug-in rail 97. A guide groove 98 is fixedly installed at the bottom of the connecting rod.

[0033] When it is necessary to scrape and clean the coupling grease on the surface of the reinforced concrete pile, rotate the handwheel 95 to drive the threaded rod 92 to rotate, and simultaneously drive the threaded rod 92 and the plug-in rail 97 on it to move backward, and at the same time drive the scraper 96 to move backward until the scraper 96 is in contact with the surface of the reinforced concrete pile. Use the scraper 96 to scrape off the residual grease on the reinforced concrete pile. The scraped grease is collected through the guide groove 98. The scraper 96 is installed on the plug-in rail 97 by plug-in installation. The scraper 96 is detachable and can be easily replaced according to the size of the reinforced concrete pile.

[0034] It should be noted that, in use, this reinforced concrete defect detection device uses an external feeding mechanism to automatically feed cylindrical reinforced concrete piles. The piles are transported to the guide mechanism 8, which guides and limits the cylindrical reinforced concrete piles to ensure they accurately enter the cleaning mechanism 7. The servo motor 741 is then activated, and its output drives the second transmission shaft 742 to rotate, simultaneously driving the drive spur gear 744 to rotate, which in turn drives the gear ring 72 and its rotating parts. The rotating ring 711 rotates synchronously, driving the cleaning brush 714 to rotate as well. The cleaning brush 714 cleans the outer wall of the reinforced concrete pile. The external feeding mechanism continuously feeds the pile until the cleaned reinforced concrete pile enters the spiral conveyor roller 21. During the rotation of the servo motor 741, the two spiral conveyor rollers 21 rotate in opposite directions synchronously through the transmission component 26 and the synchronization component 22. The spiral conveyor rollers 21 allow the cylindrical reinforced concrete pile to rotate and move forward simultaneously. Then, the CCD vision camera 6 visually inspects the pile for defects. Visual detection involves taking multiple photos, which are then transmitted to the backend system for automatic detection and judgment. After visual detection, when the front, middle, and rear ends of the reinforced concrete pile are directly below the pressing detection mechanism 4, the conveying of the reinforced concrete pile is stopped, and the telescopic cylinder 41 is activated. The output end of the telescopic cylinder 41 retracts, causing the support plate 42 and the soft oil bladder 43 on it to move upward. The soft oil bladder 43 presses against the top wall of the fixed arm 3. At this time, the coupling grease stored in the soft oil bladder 43 enters the silicone pad 44 through the delivery pipe 46 and is then squeezed out from the oil hole. At this time, the output end of the telescopic cylinder 41 moves downward, driving the support plate 42 and the ultrasonic sensor probe 45 on it to move downward, and simultaneously driving the silicone pad 44 to move downward until the silicone pad 44 is tightly attached to the top of the reinforced concrete pile. The coupling grease fills the gap between the reinforced concrete pile and the silicone pad 44, resulting in uniform coupling without air bubbles, improving the stability of ultrasonic wave transmission, reducing the amount of manual oiling work, and providing strong controllability. Subsequently, the ultrasonic sensor probe 45 and ultrasonic instrument are used to detect the inside of the reinforced concrete pile, realizing the combination of internal and external detection, and achieving high detection accuracy.

[0035] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
