Description

Technical Field

[0001] This invention relates to the field of concrete bubble content testing technology, specifically to an alkali-activated coral concrete bubble content testing device. Background Technology

[0002] Concrete bubble content testing technology focuses on quantifying the number, size distribution, and spatial morphology of bubbles inside concrete. Its core objective is to evaluate the frost resistance, impermeability, workability, and mechanical properties of concrete by detecting bubble characteristics.

[0003] Existing, many traditional concrete bubble content testing devices are typically designed for standard-sized concrete specimens. These devices use fixed clamps whose dimensions and structures are designed according to standard specimen specifications. However, alkali-activated coral concrete samples have different dimensions, and existing clamps cannot provide sufficient clamping range. As a result, the clamps cannot effectively clamp and fix alkali-activated coral concrete of different sizes, leading to micro-displacement of the alkali-activated coral concrete during the testing process. This affects the final bubble count and size distribution, causing deviations from the actual situation and resulting in low testing accuracy.

[0004] Therefore, we propose an alkali-activated coral concrete bubble content testing device to solve the problems mentioned above. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This device, through the setting of clamping components, uses a motor to drive the output shaft to rotate, which in turn drives the second gear to rotate. The second gear drives the meshing first and third gears to rotate, and the first gear drives the first toothed clutch ring to rotate. At this time, the hydraulic rod drives the rotating first toothed clutch ring to mesh with the first toothed clutch teeth, thereby driving the bidirectional threaded rod to rotate. The bidirectional threaded rod drives the two clamping frames to move towards each other to clamp and fix alkali-activated coral concrete samples of different sizes, preventing sample movement during testing and improving testing accuracy. This solves the problem in existing concrete bubble content testing equipment where the clamps are difficult to effectively clamp and fix alkali-activated coral concrete of different sizes, resulting in micro-displacement during testing and low inspection accuracy.

[0018] 2. This device, through the installation of an air supply component, electrically drives the second gear to rotate. The second gear drives the meshing first and third gears to rotate. At this time, the hydraulic rod drives the rotating second toothed ring to mesh with the second toothed gear, thereby driving the second rotating shaft to rotate. The second rotating shaft drives the eccentric wheel to rotate, thereby driving the piston to move in the first pipe. The elastic force of the third spring drives the piston to move back and forth in the first pipe, thus realizing automatic air injection in the test chamber, improving testing efficiency and reducing human operation errors.

[0019] 3. This device incorporates a movable component. Pressing the disc moves the second fixed rod, which in turn moves the first and second movable plates. These plates then move the stop block, causing its outer surface to move out of the inner wall of the groove and hole, no longer fitting against them. At this point, the sliding cylinder can be moved to move the camera according to the size of the alkali-activated coral concrete, replacing the traditional bolt fixing method, avoiding bolt stripping issues, and improving operational convenience.

A first gear 207 is fixedly connected to one side of the outer surface of a toothed locking ring 206. A motor 208 is fixedly connected to the outer surface of the test box 1 by screws. An output shaft 209 is fixedly connected to the output end of the motor 208. A second gear 210 is fixedly sleeved on the outer surface of the output shaft 209. A second rotating shaft 211 is movably fitted near the edge of one side of the outer surface of the test box 1. A second toothed locking tooth 212 is fixedly sleeved near one end of the outer surface of the second rotating shaft 211. A second toothed locking ring 213 is movably sleeved on the outer surface of the second rotating shaft 211. A third gear 214 is fixedly connected to one outer surface. A bidirectional threaded rod 201 is movably embedded in the inner wall of the test chamber 1. Two sliders 202 are threadedly connected to the outer surface of the bidirectional threaded rod 201. A clamping frame 203 is fixedly connected to the outer surface of each slider 202. The outer surfaces of both sliders 202 are slidably connected to the inner wall of the test chamber 1. The inner wall of the first gear 207 is slidably connected to the outer surface of the first rotating shaft 204. One end of the first rotating shaft 204 is fixedly connected to one end of the bidirectional threaded rod 201. The outer surface of the second gear 210 is slidably connected to the outer surface of the first gear 207. The outer surfaces of the gear 207 mesh with each other, the outer surface of the third gear 214 meshes with the outer surface of the second gear 210, the inner wall of the third gear 214 is slidably connected to the outer surface of the second shaft 211, and an eccentric wheel 215 is fixedly sleeved on the outer surface of the second shaft 211 near the other end. A hydraulic rod 216 is fixedly connected to one side of the outer surface of the test box 1 at the top of the motor 208 by screws. One end of the hydraulic rod 216 is fixedly connected to the first fixing frame 217, and the inner wall of one side of the first fixing frame 217 is rotatably connected to the outer surface of the first toothed ring 206.

[0035] In this embodiment, when it is necessary to clamp the alkali-activated coral concrete, the alkali-activated coral concrete is placed between two clamping frames 203. The motor 208 is started, and the motor 208 drives the output shaft 209 to rotate. The output shaft 209 drives the second gear 210 to rotate, and the second gear 210 drives the meshing first gear 207 and third gear 214 to rotate. The first gear 207 drives the first toothed ring 206 to rotate. The inner walls of the first toothed ring 206 and the first gear 207 rotate along the outer surface of the first rotating shaft 204, and the outer surface of the first toothed ring 206 rotates along the inner wall of the first fixing frame 217. The third gear 207 rotates along the inner wall of the first fixing frame 217. 14 will drive the second toothed ring 213 to rotate. The inner walls of the third gear 214 and the second toothed ring 213 will rotate along the outer surface of the second rotating shaft 211. The outer surface of the second toothed ring 213 will rotate along the inner wall of the first fixed frame 217. At this time, the hydraulic rod 216 is activated to drive the first fixed frame 217 to move towards the test box 1. The first fixed frame 217 will simultaneously drive the first toothed ring 206 and the second toothed ring 213 to move. The second toothed ring 213 will drive the third gear 214 to move away from the second toothed tooth 212. The first toothed ring 206 will drive the first gear 207 to move towards the first toothed tooth 205. The inner wall of the first toothed ring 206 meshes with the outer surface of the first toothed tooth 205. The rotating first toothed ring 206 drives the first toothed tooth 205 to rotate, which in turn drives the bidirectional threaded rod 201 to rotate. The bidirectional threaded rod 201 then drives the outer surfaces of the two sliders 202 to slide along the inner wall of the test chamber 1. The sliders 202 then drive the clamping frame 203 to clamp the alkali-activated coral concrete. This device, by setting the clamping assembly 2, drives the output shaft 209 to rotate via the starting motor 208. The output shaft 209 drives the second gear 210 to rotate, which in turn drives the meshing first gear 207 and third gear 208. 14. Rotation of the first gear 207 will drive the first toothed ring 206 to rotate. At this time, the hydraulic rod 216 drives the rotating first toothed ring 206 to mesh with the first toothed teeth 205, thereby driving the bidirectional threaded rod 201 to rotate. The bidirectional threaded rod 201 drives the two clamping frames 203 to move towards each other to clamp and fix alkali-activated coral concrete samples of different sizes, preventing sample movement during testing and improving testing accuracy. This solves the problem that the clamps of traditional concrete bubble content testing equipment in the prior art are difficult to effectively clamp and fix alkali-activated coral concrete of different sizes, which easily leads to micro-displacement during testing and low inspection accuracy.

[0036] like Figure 1-11As shown, the inner wall of the other side of the first fixing frame 217 is rotatably connected to the outer surface of the second toothed ring 213. The air supply assembly 3 includes a second fixing frame 301. The outer surface of the second fixing frame 301 is fixedly connected to the outer surface of the test chamber 1. A first pipe 302 is fixedly connected to the inner wall of the second fixing frame 301. A second pipe 303 is fixedly connected to the outer surface of the first pipe 302. A first fixing plate 304 is fixedly connected to the inner wall of the second pipe 303. A first spring 305 is provided on the outer surface of the first fixing plate 304. One end of the first spring 305 is fixedly connected to the outer surface of the first fixing plate 304. A first baffle 306 is fixedly connected to the other end of the first spring 305. The outer surface of the first baffle 306 is in contact with the inner wall of the second pipe 303 near one end. A third pipe 307 is fixedly connected to the outer surface of the first pipe 302. A second fixing plate 308 is fixedly connected to the inner wall of the third pipe 307. A second spring 309 is provided on the surface. One end of the second spring 309 is fixedly connected to the outer surface of the second fixed plate 308, and the other end of the second spring 309 is fixedly connected to a second baffle 310. One side of the outer surface of the second baffle 310 is in contact with one end of the third pipe 307. The outer surface of the third pipe 307 is fixedly embedded in the inner wall of the test chamber 1. A piston 313 is in contact with the inner wall of the first pipe 302. A moving shaft 311 is fixedly connected to one side of the outer surface of the piston 313. The outer surface of the moving shaft 311 is in contact with the inner wall of the first pipe 302. One end of the moving shaft 311 is fixedly connected to a moving block 312. One side of the outer surface of the moving block 312 slides against the outer surface of the eccentric wheel 215. A third spring 314 is provided on the other side of the outer surface of the piston 313. One end of the third spring 314 is fixedly connected to one side of the outer surface of the piston 313, and the other end of the third spring 314 is fixedly connected to the inner wall of the first pipe 302 near one end.

[0037] In this embodiment, after clamping the alkali-activated coral concrete, the surface of the alkali-activated coral concrete is photographed by camera 419. At this time, the operator rotates the cover plate 7 to make the sealing strip 8 fit against the top and inner wall of the test chamber 1. At this time, the pressure inside the test chamber 1 is constant, and the pressure gauge body 6 will detect the pressure inside the test chamber 1. The motor 208 is started to drive the second gear 210 to rotate. The second gear 210 will drive the first gear 207 and the third gear 214 to rotate. The third gear 214 will drive the outer surface of the second toothed ring 213 to rotate along the inner wall of the first fixing frame 217. The hydraulic rod 216 is started to move the first fixing frame 217 towards the motor 208. This will cause the second toothed ring 213 to move towards the second toothed tooth 212 until the inner wall of the second toothed ring 213 meshes with the outer surface of the second toothed tooth 212, thereby causing the second toothed tooth 212 to rotate. The second toothed tooth 212 will cause the second rotating shaft 211 to rotate, and the second rotating shaft 211 will cause the eccentric wheel 215 to rotate. When the eccentric wheel 215 rotates, it will cause the moving block 312 to move. The moving block 312 will cause the moving shaft 311 to move. The moving shaft 311 will cause the outer surface of the piston 313 to move along the inner wall of the first pipe 302, while simultaneously compressing the third spring 314. At this time, when the piston 313 moves inside the first pipe 302, it will compress the gas inside the first pipe 302, and the gas pressure inside the first pipe 302 will increase. When the second baffle 310 is no longer in contact with one end of the third pipe 307, the first baffle 306 stretches the second spring 309, and the outer surface of the first baffle 306 comes into contact with the inner wall of the second pipe 303. Gas in the first pipe 302 flows through the third pipe 307 into the test chamber 1. Meanwhile, the eccentric wheel 215 continues to rotate. The spring force of the third spring 314 drives the piston 313 to move back and forth in the first pipe 302. The piston 313 drives the moving shaft 311 to move, and the moving shaft 311 causes the outer surface of the moving block 312 to come into contact with the outer surface of the eccentric wheel 215. At this time, the movement of the piston 313 by the third spring 314 generates suction. When the outer surface of one side of the second baffle 310 comes into contact with one end of the third pipe 307, the first baffle 306 moves. The first baffle 306 compresses the first spring 305, and the outer surface of the first baffle 306 is no longer in contact with the inner wall of the second pipe 303. At this time, the external gas flows into the interior of the first pipe 302 through the interior of the second pipe 303. Then, the eccentric wheel 215 continues to rotate, driving the moving block 312 to move again. The eccentric wheel 215 and the third spring 314 drive the piston 313 to move back and forth in the first pipe 302 to inflate the test chamber 1. Based on Boyle's Law and the positive pressure comparison method, the initial pressure and final pressure in the test chamber 1 are detected by the pressure gauge body 6.The results are transmitted to the data collection and analysis display 5, and the data from the camera 419 photographing the surface of the alkali-activated coral concrete is analyzed to obtain more accurate test results for the bubble content of the alkali-activated coral concrete. This device uses an air supply component 3, where a motor 208 drives a second gear 210 to rotate. The second gear 210 drives the meshing first gear 207 and third gear 214 to rotate. At this time, a hydraulic rod 216 drives a rotating second toothed ring 213 to mesh with a second toothed tooth 212, thereby driving a second rotating shaft 211 to rotate. The second rotating shaft 211 drives an eccentric wheel 215 to rotate, which in turn drives a piston 313 to move within the first pipe 302. The elastic force of a third spring 314 drives the piston 313 to move back and forth within the first pipe 302, thus achieving automatic air injection within the test chamber 1, improving testing efficiency and reducing human error.

[0038] like Figure 1-11As shown, the moving component 4 includes a third fixing frame 401. The outer surface of the third fixing frame 401 is fixedly connected to the outer surface of the other side of the test chamber 1.

The inner walls of the two stop blocks 407 are slidably connected to the outer surface of the first fixed shaft 405 near both ends. Two third fixed plates 408 are fixedly connected to the outer surface of each of the two stop blocks 407. The four third fixed plates 408 are grouped in pairs.

A third fixed shaft 412 is movably embedded between the inner walls of the first movable plate 410 and the second movable plate 411. Connecting blocks 413 are fixedly connected to both ends of the third fixed shaft 412. Second fixed rods 414 are fixedly connected to the outer surfaces of the two connecting blocks 413. A disc 415 is fixedly connected between the outer surfaces of the two second fixed rods 414. A fifth spring 416 is provided on one outer surface of the disc 415. One end of the fifth spring 416 is connected to the disc 415. The outer surface of the fifth spring 416 is fixedly connected to the outer surface of the third fixing frame 401. The inner wall of the slide cylinder 403 is provided with multiple round holes 417. The inner wall of the fixing cylinder 402 is provided with two opposing round grooves 418 near one end. A camera 419 is provided at one end of the slide cylinder 403. A data collection and analysis display 5 is provided on one side of the outer surface of the test chamber 1.

A sealing strip 8 is fixedly connected to one side of the outer surface of both cover plates 7.

[0039] In this embodiment, after the alkali-activated coral concrete is clamped, the camera 419 can be used to photograph the bubble content on the surface of the alkali-activated coral concrete to perform a preliminary detection of the bubble content. At this time, the camera 419 can be moved according to the size of the alkali-activated coral concrete. Pressing the disc 415 will cause the second fixing rod 414 to move and simultaneously compress the fifth spring 416. The second fixing rod 414 will cause the connecting block 413 to move, and the connecting block 413 will cause the third fixing shaft 412 to move. The third fixing shaft 412 will cause the first moving plate 410 and the second moving plate 411 to rotate. The inner wall of one side of the first moving plate 410 and the second moving plate 411 will move along... As the outer surface of the third fixed shaft 412 rotates and moves, the inner walls of the other side of the first moving plate 410 and the second moving plate 411 rotate and move along the outer surface of the second fixed shaft 409. The second fixed shaft 409 drives the third fixed plate 408 to move, and the third fixed plate 408 drives the two stops 407 to move towards each other. The inner walls of the two stops 407 slide along the outer surface of the first fixed shaft 405 and move towards each other to compress the fifth spring 416. At the same time, the outer surfaces of the two stops 407 slide against the inner walls of the circular groove 418 and the circular hole 417 in sequence until the outer surfaces of the stops 407 are no longer in contact with the inner walls of the circular groove 418 and the circular hole 417. At this time, the sliding cylinder 403 is moved, and the sliding cylinder 403 drives the camera 419 to enter. The camera 419 is moved until the distance between it and the external concrete is appropriate. At this point, the operator stops pressing the disc 415, and the fifth spring 416 pushes the disc 415 to move. The disc 415 then moves the second fixed rod 414, which in turn moves the third fixed shaft 412. The third fixed shaft 412 then rotates the first moving plate 410 and the second moving plate 411. The first and second moving plates 410 and 411 move the stop block 407. Simultaneously, the fourth spring 406 pushes the inner wall of the stop block 407 to slide along the outer surface of the first fixed shaft 405 until the two stops 407 slide into the inner walls of the circular hole 417 and the circular groove 418 in sequence. At this point, the outer surface of the stop block 407... The camera 419, in contact with the inner walls of the circular hole 417 and the circular groove 418, captures images of the outer surface of the concrete. These images are then transmitted to the data collection and analysis display 5. The device utilizes a moving assembly 4. Pressing the disc 415 moves the second fixed rod 414, which in turn moves the first moving plate 410 and the second moving plate 411. These moving plates then move the stop block 407, causing its outer surface to move out of contact with the inner walls of the circular groove 418 and the circular hole 417. At this point, the sliding cylinder 403 can be moved to adjust the camera 419 according to the size of the alkali-activated coral concrete, replacing the traditional bolt fixing method.This avoids bolt stripping issues and improves operational convenience.

[0040] The usage and working principle of this device: When using an alkali-activated coral concrete bubble content testing device, the operator places the concrete on the inner wall of the test chamber 1, between the two clamping frames 203. The motor 208 is then started, driving the output shaft 209 to rotate. The output shaft 209 drives the second gear 210 to rotate, which in turn drives the meshing first gear 207 and third gear 214 to rotate. The first gear 207 drives the first toothed ring 206 to rotate. The inner walls of the first toothed ring 206 and the first gear 207 rotate along the outer surface of the first rotating shaft 204. The outer surface of the first toothed ring 206 rotates along the inner wall of the first fixed frame 217. The third gear 214... 4 will drive the second toothed ring 213 to rotate. The inner walls of the third gear 214 and the second toothed ring 213 will rotate along the outer surface of the second rotating shaft 211. The outer surface of the second toothed ring 213 will rotate along the inner wall of the first fixed frame 217. At this time, the hydraulic rod 216 will be activated to drive the first fixed frame 217 to move towards the test box 1. The first fixed frame 217 will simultaneously drive the first toothed ring 206 and the second toothed ring 213 to move. The second toothed ring 213 will drive the third gear 214 to move away from the second toothed tooth 212. The first toothed ring 206 will drive the first gear 207 to move towards the first toothed tooth 205 until the inner wall of the first toothed ring 206 meshes with the outer surface of the first toothed tooth 205. The rotating first toothed ring 206 drives the first toothed tooth 205 to rotate, which in turn drives the bidirectional threaded rod 201 to rotate. The bidirectional threaded rod 201 drives the outer surfaces of the two sliders 202 to slide along the inner wall of the test chamber 1. The sliders 202 drive the clamping frame 203 to clamp the concrete. At this time, the motor 208 is stopped, and the camera 419 is moved to take pictures of the outer surface of the concrete to analyze the air bubble content. At this time, the disc 415 is pressed, which drives the second fixed rod 414 to move and simultaneously compresses the fifth spring 416. The second fixed rod 414 drives the connecting block 413 to move, which in turn drives the third fixed shaft 412 to move. This will cause the first moving plate 410 and the second moving plate 411 to rotate and move. The inner wall of one side of the first moving plate 410 and the second moving plate 411 will rotate and move along the outer surface of the third fixed shaft 412. The inner wall of the other side of the first moving plate 410 and the second moving plate 411 will rotate and move along the outer surface of the second fixed shaft 409. The second fixed shaft 409 will drive the third fixed plate 408 to move. The third fixed plate 408 will drive the two stops 407 to move towards each other. The inner walls of the two stops 407 will slide along the outer surface of the first fixed shaft 405 and move towards each other to compress the fifth spring 416. At the same time, the outer surfaces of the two stops 407 will successively slide against the inner walls of the circular groove 418 and the circular hole 417.Until the outer surface of the stop 407 is no longer in contact with the inner wall of the groove 418 and the hole 417, the slide cylinder 403 is moved. The slide cylinder 403 will drive the camera 419 to move until the distance between the camera 419 and the external concrete is appropriate. At this time, the camera 419 will take a picture of the outer surface of the external concrete, and the formed image will be transmitted to the data collection and analysis display 5. Then, the cover plate 7 is rotated to make the sealing strip 8 fit with the top and inner wall of the test chamber 1. At this time, the pressure inside the test chamber 1 is determined, and the pressure gauge body 6 will detect the pressure inside the test chamber 1 at this time. The motor 208 is started again to drive the second gear 210 to rotate. The second gear 210 will drive the first gear 207 and the third gear 214 to rotate. The pressure rod 216 drives the first fixed frame 217 to move towards the motor 208. The first fixed frame 217 drives the second toothed ring 213 to move towards the second toothed tooth 212 until the inner wall of the second toothed ring 213 meshes with the outer surface of the second toothed tooth 212, thereby causing the second toothed tooth 212 to rotate. The second toothed tooth 212 drives the second rotating shaft 211 to rotate, and the second rotating shaft 211 drives the eccentric wheel 215 to rotate. When the eccentric wheel 215 rotates, it drives the moving block 312 to move. The moving block 312 drives the moving shaft 311 to move. The moving shaft 311 drives the outer surface of the piston 313 to move along the inner wall of the first pipe 302, while stretching the third spring 314. At this time, the piston 313 is... When the first pipe 302 moves internally, it compresses the gas inside the first pipe 302. The increased gas pressure in the first pipe 302 pushes one side of the outer surface of the second baffle 310 away from contact with one end of the third pipe 307. When the second baffle 306 is no longer in contact with the inner wall of the second pipe 303, the outer surface of the first baffle 306 will contact the inner wall of the second pipe 303. The gas in the first pipe 302 will flow into the test chamber 1 through the interior of the third pipe 307. At the same time, the eccentric wheel 215 continues to rotate. At this time, the elastic force of the third spring 314 will drive the piston 313 to move back and forth in the first pipe 302. The piston 313 will drive the moving shaft 311 to move. The moving shaft 311 will drive the outer surface of the moving block 312 to contact the outer surface of the eccentric wheel 215. When the third spring 314 moves the piston 313, it generates suction. This suction causes one outer surface of the second baffle 310 to come into contact with one end of the third pipe 307. Simultaneously, the first baffle 306 moves, compressing the first spring 305. At the same time, the outer surface of the first baffle 306 is no longer in contact with the inner wall of the second pipe 303. At this point, external gas flows through the interior of the second pipe 303 into the interior of the first pipe 302. Then, the eccentric wheel 215 continues to rotate, again moving the moving block 312. The eccentric wheel 215 and the third spring 314 drive the piston 313 to move back and forth within the first pipe 302, thus inflating the test chamber 1. This is based on Boyle's Law and the positive pressure comparison method.The initial and final pressures inside the test chamber 1 are measured using the pressure gauge body 6, and the results are then transmitted to the data collection and analysis display 5.
