Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of slump detection, in particular to a building concrete slump detection device. BACKGROUND

[0002] The slump of concrete mainly refers to the plasticizing performance and pumpability of concrete. The factors affecting the slump of concrete mainly include gradation variation, water content, weighing deviation of the weighing device, dosage of the admixture, and the temperature of cement which is easily ignored. The slump refers to the workability of concrete, which specifically ensures the normal construction, including the water retention, fluidity and cohesiveness of concrete. The workability refers to the performance of concrete being easy to operate and uniform and dense, which is a very comprehensive performance including fluidity, cohesiveness and water retention. The workability is mainly affected by the water consumption, water-cement ratio, sand ratio, and several aspects including cement variety, aggregate condition, time and temperature, and admixture. The slump of concrete should be determined according to the structural section of the building, the content of steel bars, the transportation distance, the pouring method, the transportation mode, the vibration capacity and the climate, should be comprehensively considered when selecting the mixing proportion, and the smaller slump should be adopted.

[0003] According to the building concrete slump detection device disclosed in the patent CN215449280U, it can be known that the existing slump cylinder needs to be inverted on the ground during detection. In order to make the concrete in the slump cylinder more uniformly and closely distributed, the concrete is shaken and shaken in a knocking manner to make the concrete shake uniformly. When the slump cylinder is lifted, a large adhesion force is generated between the inner wall of the slump cylinder and the concrete, which easily drives a part of the concrete to lift together, affects the overall free falling of the concrete, causes the measurement of the slump to deviate, and the slump directly calculated by the height of the top end is affected by the local blocky concrete. The spreading area and the shape of the concrete after the slump also affect the detection result. Therefore, the present application provides a building concrete slump detection device. SUMMARY

[0004] The present application aims to provide a building concrete slump detection device which can reduce the error caused by the uniformity and adhesion of concrete during detection and improve the detection accuracy, so as to solve the problems in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a slump testing device for building concrete, comprising a base, a sealing mechanism, a shaking mechanism, a lifting mechanism, a measuring mechanism, and a slump cylinder. A mounting frame is fixedly connected to the base, and two sets of rotating frames are rotatably connected to the outer wall of the base. The sealing mechanism includes a sealing ring fixedly installed on the base. The sealing mechanism seals the bottom end of the slump cylinder while providing an elastic fit, making it easier to generate vibration while the bottom end of the slump cylinder is sealed. The shaking mechanism includes multiple sets of impact blocks, which drive the impact blocks to sequentially impact the outer wall of the slump cylinder. The lifting mechanism, mounted on the mounting frame, generates a shaking motion. When the rotating frame rotates forward, it is linked to the shaking mechanism, simultaneously removing concrete adhering to the inner wall of the slump cylinder, reducing the adhesion between the concrete and the inner wall of the slump cylinder. When the rotating frame rotates in the reverse direction, it drives the slump cylinder to move upward rapidly, thereby pouring out the internal concrete for slump testing. The measuring mechanism, mounted on the mounting frame, is used to detect the maximum height, slump area, and overall shape of the concrete after slump, assisting in comprehensive slump calculation. This helps reduce errors caused by concrete uniformity and adhesion during testing, improving testing accuracy.

[0006] Preferably, the lifting mechanism includes an adjusting frame installed on the upper end of the rotating frame, an adjusting block slidably connected to the adjusting frame in the horizontal direction, multiple sets of fixing rods fixedly connected to the slumping cylinder, multiple sets of plug-in rods that are inserted into the fixing rods fixedly connected to the adjusting block, a certain gap between the fixing rods and the plug-in rods, a screw threadedly connected to the adjusting frame, a driving component for driving the rotating frame to rotate on the base, and a scraping component inside the slumping cylinder for reducing the adhesion between the slumping cylinder and the concrete when the slumping cylinder rotates, facilitating the lifting operation of the slumping cylinder.

[0011] Preferably, the sealing mechanism further includes a plug ring fixedly installed at the bottom end of the slump cylinder. The base has a plug groove, the plug ring is movably connected to the plug groove, the sealing ring is installed on both sides of the plug groove, and a lifting ring is slidably connected to the bottom end of the plug groove. A first spring fixedly connected to the bottom surface of the lifting ring and fixedly connected to the plug groove is used to prevent concrete from overflowing from the gap at the bottom end of the slump cylinder during the shaking process.

[0012] Preferably, the driving component includes a drive motor fixedly installed in the base, a first gear coaxially fixedly connected to the output end of the drive motor, an internal gear ring rotatably connected to the base and meshing with the first gear, two sets of rotating frames fixedly connected to the outer wall of the internal gear ring, a rotating rod rotatably connected to the rotating frame, a second gear coaxially fixedly connected to the bottom surface of the rotating rod, an external gear ring meshing with the second gear fixedly connected to the base, and a control component provided inside the rotating frame for controlling the adjusting frame to move downward and linking the impact block to perform impact vibration when rotating in the forward direction, and controlling the adjusting frame to rise rapidly when rotating in the reverse direction, so as to facilitate the rotation of the rotating frame.

[0013] Preferably, the control component includes a sleeve rod fixedly installed at the bottom end of the adjusting frame.

A fourth spring fixedly connected to the rotating frame is fixedly connected to the bottom end of the sleeve rod. A threaded groove is formed inside the sleeve rod.

[0014] Preferably, the shovel includes a first ring rotatably connected to the inner wall of the bottom end of the slump cylinder, a second ring rotatably connected to the inner wall of the upper end of the slump cylinder, a shovel plate fixedly connected between the first ring and the second ring and slidably connected to the inner wall of the slump cylinder, a plurality of limit rods fixedly connected to the lifting plate, and a plurality of limit grooves provided on the second ring for inserting into the limit rods, so as to reduce the adhesion between the slump cylinder and the concrete when the slump cylinder rotates.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. This invention provides a slump testing device for building concrete. A connector ring is inserted into a connector groove, and a lifting ring is pressed down. The two sides are sealed by the sealing rings, providing a good sealing effect on the bottom of the slump cylinder. Simultaneously, the rubber has a certain elasticity, reducing the impact on the vibration frequency and amplitude during subsequent shaking. When the slump cylinder is raised, a first spring automatically lifts the lifting ring, ensuring the upper surface of the base is relatively flat. Adjusting the position of the second ring causes the limiting rod to contact the limiting groove. Rotating the screw moves the adjusting frame to both sides of the slump cylinder, allowing the connector rod to be inserted into the gap between the fixing rod. The gap between the connector rod and the fixing rod ensures that the connector rod only drives the rotation of the fixing rod and the slump cylinder, and provides an elastic buffer space. The inclined tooth block is then inserted into the inclined tooth groove, and the concrete to be tested is injected into the feed hopper for subsequent slump testing.

[0017] 2. The present invention provides a slump testing device for building concrete. A laser emitter emits a strip of light to one side of a scale plate. This light passes precisely through the axis of the base and the center of the collapsed concrete. At this time, the light from the lower side is blocked by the concrete. The height of the collapsed concrete is the lowest mark on the scale plate illuminated by the light. At the same time, the diffusion range of the collapsed concrete can be obtained by observing the correspondence between the edge of the concrete and the annular scale groove. The detection probe is driven by a rotating frame to scan around the concrete to obtain the outline of the collapsed concrete. If the outline is a relatively smooth cone shape, it indicates that the uniformity of the concrete is good and the slump is relatively accurate.

[0018] 3. The present invention provides a slump testing device for building concrete. When concrete is added, the drive motor is started and rotated in the forward direction, driving the first gear to rotate the internal gear ring, which in turn drives the rotating rod to rotate. The guide block rotates from the threaded groove to the annular groove and continues to rotate. As the rotating frame rotates continuously, the helical tooth block pushes the helical tooth groove to rotate the rotating ring. The actuating column above the rotating ring continuously contacts the top arc surface of the impact block and pushes the impact block to compress the second spring. The rebound of the second spring pushes the impact block to impact the outer wall of the slump cylinder. The vibration makes the concrete evenly distributed inside the slump cylinder. The plug rod drives the fixing rod, so that the entire slump cylinder rotates together with the rotating frame. This allows the inner wall of the slump cylinder to be continuously scraped by the shovel plate, reducing the adhesion between the inner wall and the concrete, which facilitates subsequent lifting and demolding.

[0019] 4. The present invention provides a slump testing device for building concrete. When concrete is added to a set height, the drive motor is started to rotate in the reverse direction, which causes the rotating frame to rotate in the reverse direction. The guide block slides from the annular groove to the threaded groove, lifting the sleeve rod and lifting the rotating ring and lifting plate together. The slump cylinder is raised. When the rotating frame rotates in the reverse direction, the inclined surface of the inclined tooth block contacts the inclined tooth groove. At this time, the rotation of the inclined tooth block will not drive the rotating ring to rotate, avoiding impact and shaking during the lifting process that affects the free slump of the concrete. At the same time, the slump cylinder still rotates relative to the shovel plate when it moves upward, reducing adhesion and avoiding concrete residue, making the test results more accurate. After the structure is measured, the concrete can be removed, the slump cylinder can be lowered and the fixing of the slump cylinder can be released, and the slump cylinder can be disassembled and cleaned for the next test.

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.

[0034] Please see Figures 1-12 This invention provides a technical solution: a slump testing device for building concrete, comprising a base 1, a sealing mechanism 5, a shaking mechanism 7, a lifting mechanism 9, a measuring mechanism 10, and a slump cylinder 2. A mounting frame 3 is fixedly connected to the base 1, and two sets of rotating frames 4 are rotatably connected to the outer wall of the base 1. The sealing mechanism 5 includes a sealing ring 6 fixedly installed on the base 1, the sealing ring 6 being made of rubber. The sealing mechanism 5 seals the bottom end of the slump cylinder 2 while providing an elastic fit, making it easier to generate vibration while the bottom end of the slump cylinder 2 is sealed. The shaking mechanism 7 includes multiple sets of impact blocks 8 and a shaking device. Mechanism 7 is used to drive the impact block 8 to impact the outer wall of the slump cylinder 2 in sequence to generate vibration. Lifting mechanism 9 is installed on the mounting frame 3 and is used to link the vibration mechanism 7 when the rotating frame 4 rotates in the forward direction. At the same time, it removes the concrete adhering to the inner wall of the slump cylinder 2 to reduce the adhesion between the concrete and the inner wall of the slump cylinder 2. When the rotating frame 4 rotates in the reverse direction, it drives the slump cylinder 2 to move upward quickly, thereby pouring out the internal concrete for slump detection.

[0037] The lifting mechanism 9 includes an adjusting frame 11 installed on the upper end of the rotating frame 4. An adjusting block 12 is slidably connected to the adjusting frame 11 in the horizontal direction. Multiple sets of fixing rods 13 are fixedly connected to the slumping cylinder 2. Multiple sets of plug rods 14 that are inserted into the fixing rods 13 are fixedly connected to the adjusting block 12. There is a certain gap between the fixing rods 13 and the plug rods 14. A screw 15 that is threadedly connected to the adjusting block 12 is rotatably connected to the adjusting frame 11. A driving component 16 for driving the rotating frame 4 to rotate is provided on the base 1. A scraping component 17 is provided inside the slumping cylinder 2 for reducing the adhesion between the slumping cylinder 2 and the concrete when the slumping cylinder 2 rotates.

A lifting plate 19 is fixedly connected to the sliding rod 18. Multiple sets of impact blocks 8 are evenly installed on the lifting plate 19 and slidably connected to the lifting plate 19 in the horizontal direction. A feed hopper 20 is fixedly connected to the upper end of the lifting plate 19. A second spring 21 that is fixedly connected to the lifting plate 19 is fixedly connected to one end of the impact block 8. The other end of the impact block 8 abuts against the outer wall of the collapse cylinder 2. The end of the impact block 8 near the outer wall of the collapse cylinder 2 is arc-shaped. The lifting plate 19 is provided with an impact member 22 for driving the impact block 8 to reciprocate to impact the outer wall of the collapse cylinder 2.

[0039] The impact component 22 includes a rotating ring 23 rotatably connected to the bottom surface of the lifting plate 19. Multiple sets of actuating pins 24 for actuating one end of the arc surface of the impact block 8 are fixedly connected to the rotating ring 23. The adjusting block 12 is provided with a rotating component 25 that docks with the rotating ring 23 and drives the rotating ring 23 to rotate in one direction. The rotating component 25 includes a fixed frame 26 fixedly installed on the adjusting block 12. A helical tooth block 27 is slidably connected in the horizontal direction inside the fixed frame 26. A third spring 28 fixedly connected to the fixed frame 26 is fixedly connected to one end of the helical tooth block 27. Multiple sets of helical tooth grooves 29 that can be inserted into the helical tooth block 27 are evenly opened on the outer wall of the rotating ring 23.

[0040] The driving component 16 includes a drive motor 38 fixedly installed in the base 1. The drive motor 38 is preferably a YYHS-40. The output end of the drive motor 38 is coaxially fixedly connected to a first gear 39. An internal gear ring 40 that meshes with the first gear 39 is rotatably connected to the base 1. Both sets of rotating frames 4 are fixedly connected to the outer wall of the gear ring 40. A rotating rod 41 is rotatably connected to the rotating frame 4. A second gear 42 is coaxially fixedly connected to the bottom surface of the rotating rod 41. An external gear ring 43 that meshes with the second gear 42 is fixedly connected to the base 1. The rotating frame 4 is provided with a control component 44 for controlling the adjusting frame 11 to move down and linking the impact block 8 to perform impact vibration when rotating in the forward direction, and controlling the adjusting frame 11 to rise rapidly when rotating in the reverse direction.

[0041] The control component 44 includes a sleeve rod 45 fixedly installed at the bottom end of the adjusting frame 11. The sleeve rod 45 is slidably connected to the rotating frame 4 in the vertical direction. The sleeve rod 45 is movably sleeved with the outer wall of the rotating rod 41. A fourth spring 46 fixedly connected to the rotating frame 4 is fixedly connected to the bottom end of the sleeve rod 45. A threaded groove 47 is opened in the sleeve rod 45. An annular groove 48 communicating with the upper end of the threaded groove 47 is opened in the sleeve rod 45. A spring 46 that can communicate with the threaded groove is fixedly connected to the rotating rod 41. The guide block 49 is slidably connected to the inner wall of the annular groove 48. The shovel 17 includes a first ring 50 rotatably connected to the inner wall of the bottom end of the collapse cylinder 2. A second ring 51 is rotatably connected to the inner wall of the upper end of the collapse cylinder 2. A shovel plate 52 slidably connected to the inner wall of the collapse cylinder 2 is fixedly connected between the first ring 50 and the second ring 51. Multiple sets of limiting rods 53 are fixedly connected to the lifting plate 19. Multiple sets of limiting grooves 54 that are inserted into the limiting rods 53 are opened on the second ring 51.

[0042] First, rotate the screw 15 to move the adjusting block 12 and the plug rod 14 away from the lifting plate 19. Then, pull up the lifting plate 19 to place the collapse cylinder 2 below the lifting plate 19. Insert the plug ring 34 into the plug groove 35 and press down the lifting ring 36. The two sides are sealed by the contact of the sealing ring 6. Both the sealing ring 6 and the lifting ring 36 are made of rubber, which provides a good sealing effect on the bottom of the collapse cylinder 2. At the same time, the rubber has a certain elasticity and fit, reducing the impact on the frequency and amplitude of shaking during later shaking. At the same time, when the collapse cylinder 2 is raised, the first spring 37 automatically lifts the lifting ring 36 to ensure that the upper surface of the base 1 is sealed. In a relatively flat state, lower the lifting plate 19 and adjust the position of the second ring 51 so that the limiting rod 53 abuts against the limiting groove 54. The limiting groove 54 is equipped with a rubber pad to reduce the hard contact between it and the limiting rod 53. Then rotate the screw 15 to move the adjusting brackets 11 on both sides toward the slump cylinder 2, so that the plug rod 14 is inserted into the gap of the fixed rod 13. The gap between the plug rod 14 and the fixed rod 13 ensures that the plug rod 14 only drives the rotation of the fixed rod 13 and the slump cylinder 2, and has an elastic buffer space. Insert the inclined tooth block 27 into the inclined tooth groove 29, and then inject the concrete to be tested into the feed hopper 20 to carry out the subsequent slump test.

[0043] A beam of light is emitted from the laser emitter 30 to one side of the scale plate 31. This beam passes precisely through the axis of the base 1 and the center of the collapsed concrete. The lower beam is blocked by the concrete. The height of the collapsed concrete is indicated by the light illuminating the lowest mark on the scale plate. The diffusion range of the collapsed concrete can be determined by the correspondence between the edge of the concrete and the annular scale groove 32. The detection probe 33 is driven by the rotating frame 4 to scan the area around the concrete to obtain the outline of the collapsed concrete. If the outline is a relatively smooth cone, it indicates that the concrete has good uniformity and the slump is relatively accurate. If the center of the concrete is significantly raised and the diffusion range around it is large, it indicates that there are many large solid particles in the concrete and the mixing is not uniform enough. This results in the liquid concrete not being completely mixed and spreading directly to the surrounding area after collapse, leading to an increased diffusion range. In this case, the slump detection is relatively inaccurate, and the concrete mix ratio and mixing conditions need to be readjusted.

[0044] When concrete is added, the drive motor 38 is started and rotates forward, driving the first gear 39 to rotate the internal gear ring 40. The internal gear ring 40 drives the rotating frame 4 to rotate, while the second gear 42 rolls on the external gear ring 43, which in turn drives the rotating rod 41 to rotate. The guide block 49 rotates from the threaded groove 47 into the annular groove 48 and continues to rotate. At this time, it will not drive the lifting and lowering of the sleeve rod 45. At the same time, as the rotating frame 4 continues to rotate, the helical tooth block 27 pushes the helical tooth groove 29 to make the rotating ring 23 rotate. The actuating post 24 above the rotating ring 23 continuously contacts the top arc surface of the impact block 8 and pushes the impact block 8 to compress the second spring 21. When the actuating post After the second spring 21 rebounds, it can push the impact block 8 to impact the outer wall of the slump cylinder 2. The stable state of the second spring 21 is that the top of the impact block 8 is just in contact with the outer wall of the slump cylinder 2. As concrete is continuously added, the shaking makes the concrete evenly distributed inside the slump cylinder 2. At the same time, the limiting rod 53 ensures the fixed position of the first ring 50, the second ring 51 and the shovel plate 52. The plug rod 14 drives the fixing rod 13 so that the slump cylinder 2 rotates together with the rotating frame 4. This allows the inner wall of the slump cylinder 2 to be continuously scraped by the shovel plate 52, reducing the adhesion between the inner wall and the concrete, which is convenient for subsequent lifting and demolding.

[0045] Once the concrete has reached the set height, the drive motor 38 is activated to rotate in the reverse direction, causing the rotating frame 4 to rotate in the reverse direction. The second gear 42 and the rotating rod 41 rotate in opposite directions. Driven by the fourth spring 46, the guide block 49 slides from the annular groove 48 into the threaded groove 47, lifting the sleeve rod 45. The adjusting frame 11 moves upward, and the insert rod 14 lifts the rotating ring 23 and the lifting plate 19 together. The sliding rod 18 slides upward on the fixed clamp, and simultaneously, the insert rod 14 also lifts the slump cylinder 2. The large pitch of the threaded groove 47 ensures the rapid lifting of the slump cylinder 2. The lifting plate 19 is equipped with a control mechanism... A limiting block (not shown) for unidirectional rotation of the rotating ring 23 is provided. When the rotating frame 4 rotates in the opposite direction, the inclined surface of the helical tooth block 27 contacts the helical tooth groove 29. At this time, the rotation of the helical tooth block 27 will not drive the rotating ring 23 to rotate, thus avoiding impact and vibration during the lifting process that could affect the free collapse of the concrete. At the same time, when the slump cylinder 2 moves upward, it still rotates relative to the shovel plate 52, reducing adhesion and avoiding concrete residue, making the test results more accurate. After the structure is measured, the concrete can be removed, the slump cylinder 2 can be lowered and the fixing of the slump cylinder 2 can be released, and the slump cylinder 2 can be disassembled and cleaned for the next test.
