Description

Technical Field

[0001] The present invention relates to the technical field of concrete specimen production, and in particular to a multifunctional integrated fiber concrete automatic forming machine and a use method thereof. Background Art

[0002] Concrete specimens are key to evaluating concrete's mechanical properties and durability. Their quality significantly impacts the safety and reliability of engineering structures. This is particularly true in the field of fiber-reinforced concrete, where specimen uniformity and fiber dispersion play a crucial role in performance test results. Therefore, preparing highly consistent, compliant concrete specimens is crucial for materials research, engineering quality control, and the development of industry standards. However, laboratories currently face the following challenges when preparing fiber-reinforced concrete or conventional concrete specimens:

[0003] 1. Traditional concrete specimen preparation methods usually rely on manual operation, which is not only inefficient and lacks precision, but also increases labor intensity.

[0004] 2. The concrete raw materials in the laboratory are relatively scattered. Due to the differences in properties such as moisture content among different batches of materials, it is difficult to ensure the consistency of specimens when producing specimens in large quantities.

[0005] 3. When preparing concrete specimens in the laboratory, raw material weighing is mainly done manually, which results in large errors. Furthermore, when adding raw materials to the mixer, raw material loss is likely to occur, thus affecting the performance of the concrete.

[0006] 4. During the preparation of fiber-reinforced concrete, fiber dispersion significantly impacts concrete performance. If fibers are not evenly dispersed, they can easily form clumps, leading to an uneven internal structure in the concrete and reducing its crack resistance, toughness, and durability. Currently, fiber placement and dispersion in laboratories are mostly manual, which not only makes it difficult to ensure uniform fiber distribution but also increases operational complexity and time costs.

[0007] 5. Cleaning a concrete mixer takes a lot of time and water. If not cleaned thoroughly, the concrete remaining on the mixing blades or the inner wall of the mixing barrel may solidify, resulting in a decrease in the mixing performance of the mixer.

[0008] Therefore, a multifunctional integrated fiber concrete automatic forming machine and a method of using the same are provided to solve the above problems. Summary of the Invention

[0033] The forming mold is used to form concrete test blocks, and the eccentric vibrator is used to discharge bubbles in the unsolidified slurry to make the slurry dense.

[0034] A method for using a multifunctional integrated fiber concrete automatic forming machine specifically comprises the following steps:

[0035] S1: Automatic feeding; solid materials and fibers are fed through the screw feeder and fiber dispersion unit, liquid admixtures and water are fed through the admixture feeding unit and cleaning and water supply unit, and the feeding operation is controlled in real time by the automatic control system;

[0036] S11: screw feeder feeding;

[0037] The automated control system controls the screw feed shaft drive motor to rotate at a constant speed. The material in the storage tank is transported through the mixing box hopper into the mixing box, and the fiber is transported from the storage tank to the fiber dispersion unit. Different types of materials are added in sequence. The mixing box weight sensor electrically connected to the automated control system measures the weight in the mixing box in real time. When the weight reaches the set parameter, the automated control system controls the screw feed shaft drive motor to stop working, and the feeding is completed.

[0038] S12: fiber dispersion;

[0039] The fibers are transported from the storage tank to the fiber dispersion unit by a screw feeder, initially separated by a separation grid, and fall onto the dispersion combs. The automated control system controls the dispersion shaft drive motor to rotate the dispersion shaft. The dispersion combs on the dispersion shaft disperse the bundled fibers. The dispersed fibers enter the mixing box through the mixing box hopper. The mixing box weight sensor electrically connected to the automated control system measures the weight in the mixing box in real time. When the weight reaches the set parameter, the automated control system controls the screw feed shaft drive motor and the dispersion shaft drive motor to stop working, and the fiber feeding is completed.

[0040] S13: adding liquid admixture and water;

[0041] The automated control system controls the liquid storage tank valve controller to open the liquid storage tank valve, and the liquid admixture enters the mixing tank through the mixing tank hopper. The mixing tank weight sensor electrically connected to the automated control system measures the weight in the mixing tank in real time. When the weight reaches the set parameter, the automated control system controls the liquid storage tank valve controller to close the liquid storage tank valve and stop adding the liquid admixture. The automated control system controls the pressure pump to operate at low power, and water enters the mixing tank through the spray arm. The mixing tank weight sensor electrically connected to the automated control system measures the weight in the mixing tank in real time. When the weight reaches the set parameter, the automated control system controls the pressure pump to stop working and stop adding water.

[0042] S2: Automatic stirring. When all materials are added, the automatic control system controls the mixing box hopper control valve to close the mixing box hopper. The automatic control system controls the stirring shaft drive motor to work, and the stirring blades stir the materials in the mixing box to mix. When the set time is reached, the automatic control system controls the stirring shaft drive motor to stop working and stirring stops.

[0043] S3: mold leveling;

[0044] S31: Automatic leveling detection by laser radar. When the discharge door of the mixing box is closed, the automatic control system controls the laser radar to scan the four corner points of the forming mold below. If the laser radar scans the four corner points of the forming mold, step S32 is executed. Otherwise, the position of the forming mold is adjusted until the laser radar scans the four corner points of the forming mold.

[0045] S32: Leveling: The automated control system calculates the horizontal inclination angle of the plane formed by the four mold corner points based on the distances to the four mold corner points scanned by the laser radar, and calculates the height adjustment amount of the four leveling screws based on the horizontal inclination angle;

[0046] S4: pouring;

[0047] During pouring, each mold cavity of the forming mold is filled in sequence, and the automatic control system controls the mixing box discharge door to control the motor to drive the mixing box discharge door to open outwards. The concrete in the mixing box falls into the feeding chute through the mixing box discharge door, and then enters the forming mold through the feeding chute. During this process, the automatic control system controls the eccentric vibrator to work, and the laser radar measures the height of the upper surface of the concrete in the forming mold in real time. When the upper surface of the filled concrete reaches the plane formed by the four corner points of the forming mold initially scanned, the automatic control system controls the mixing box discharge door to control the motor to drive the mixing box discharge door to close, stopping pouring, stopping the eccentric vibrator to work, and the automatic leveling forming system moves away via the leveling system bottom plate guide rail;

[0048] S5: self-cleaning;

[0049] S51: The stirring device is self-cleaning. The automatic control system controls the pressure pump to work at full power. High-pressure water drives the spray arm to rotate. The water sprayed by the spray arm flushes the stirring box, stirring blades and stirring scrapers. The automatic control system controls the stirring shaft drive motor to work, and the stirring blades rotate around the stirring shaft.

[0050] S52: The laser radar detects the cleanliness level, and the automatic control system controls the pressure pump and the stirring shaft drive motor to stop working, controls the mixing box discharge door control motor to drive the mixing box discharge door to open outward, discharges the sewage, and controls the mixing box discharge door control motor to drive the mixing box discharge door to rotate inward of the mixing box. The laser radar scans several points in the mixing box shell. If the distances to several points are consistent with the distances measured when no material is added and the box is empty, it means that the cleaning is completed. If the distance to a certain point is less than the distance measured when no material is added and the box is empty, it means that the cleaning is not thorough, and steps S51-S52 are repeated until the cleaning is completed.

[0051] S6: demoulding;

[0052] The automated control system controls the rotating platform's rotating axis drive motor to operate, causing the rotating platform's rotating axis to rotate and the rotating platform plate to flip horizontally. Compressed air will pass through the mold's one-way valve to push out the solidified test block, and then the rotating platform plate will reset to complete demoulding.

[0053] Preferably, step S32 specifically includes the following steps:

[0054] The distances measured by the laser radar from the four corner points A, B, C, and D of the forming mold are dA, dB, dC, and dD respectively. The laser radar position is the origin O, and the height is set to h. is the pitch angle of the laser radar to the corner point, is the horizontal azimuth of the laser radar to the corner point, then the three-dimensional coordinates of each corner point (xi, yi, zi), i=A, B, C, D, are expressed as:

[0055] ;

[0056] ;

[0057] ;

[0058] Choose any three points such as A, B, and C to calculate the plane equation. First calculate two vectors:

[0059] ;

[0060] ;

[0061] Then find the normal vector :

[0062] ;

[0063] ;

[0064] ;

[0065] The plane equation is expressed as:

[0066] ;

[0067] Determine whether the plane is horizontal. The necessary and sufficient condition for the plane to be horizontal is the normal vector is the vertical direction, that is and , considering the existence of true error, if and , If the tolerance is preset, the plane is level, and if it is not level, the height of the four corner points is corrected;

[0068] The correction value of each corner point is the difference between the current height and the target horizontal plane. The average height of the current plane is calculated as , corrected displacement , positive values ​​indicate that it needs to be raised, negative values ​​indicate that it needs to be lowered, and the height correction values ​​of the four corner points are obtained 、 、 、 , adjust the height of the leveling screw nut according to the height correction value;

[0069] Finally, the moving distance of the leveling screw nut after the leveling screw rotates n times is set to 1, so that the automatic control system calculates the number of turns N that the leveling screw needs to rotate based on the distance that the four leveling screw nuts need to move in the vertical direction, that is, controls the leveling motor to drive the leveling screw to rotate N times.

[0070] Therefore, the present invention adopts the above-mentioned multifunctional integrated fiber concrete automatic forming machine and its use method, which has the following beneficial effects:

[0071] (1) By setting up a fiber dispersion unit, the bundled fibers can be dispersed, thereby ensuring uniform distribution of the fibers and reducing operational complexity and time costs;

[0072] (2) The automatic leveling molding system can realize automatic leveling of the mold and prepare concrete specimens with dimensions that meet standard requirements;

[0073] (3) The automatic feeding module works in conjunction with the automatic stirring system to clean the automatic stirring system.

[0116] Example 1

[0119] S11: screw feeder 112 feeding;

[0120] The automatic control system 4 controls the spiral feeding shaft drive motor 1123 to rotate at a uniform speed, and the material in the storage tank 111 is transported through the mixing box hopper 214 into the mixing box 21, and the fiber is transported from the storage tank 111 to the fiber dispersion unit 113; different types of materials are added in sequence, and the mixing box weight sensor 213 electrically connected to the automatic control system 4 measures the weight in the mixing box in real time. When the weight reaches the set parameter, the automatic control system 4 controls the spiral feeding shaft drive motor 1123 to stop working, and the feeding is completed.

[0121] S12: fiber dispersion;

[0122] The fibers are transported from the storage tank to the fiber dispersion unit by the spiral feeder 112, undergo preliminary separation through the separation grid 1132, and fall onto the dispersion comb teeth 1133. The automatic control system 4 controls the dispersion shaft drive motor 1135 to drive the dispersion shaft 1134 to rotate. The dispersion comb teeth 1133 on the dispersion shaft 1134 disperse the bundled fibers. The dispersed fibers enter the mixing box 21 through the mixing box hopper 214. The mixing box weight sensor 213 electrically connected to the automatic control system 4 measures the weight in the mixing box 21 in real time. When the weight reaches the set parameters, the automatic control system 4 controls the spiral feeding shaft drive motor 1123 and the dispersion shaft drive motor 1135 to stop working, and the fiber feeding is completed.

[0123] S13: adding liquid admixture and water;

[0124] The automatic control system 4 controls the liquid storage tank valve controller 1241 to open the liquid storage tank valve 124, and the liquid admixture enters the mixing tank 21 through the mixing tank hopper 214. The mixing tank weight sensor 213 electrically connected to the automatic control system 4 measures the weight in the mixing tank 21 in real time. When the weight reaches the set parameter, the automatic control system 4 controls the liquid storage tank valve controller 1241 to close the liquid storage tank valve 124 and stop adding the liquid admixture; the automatic control system 4 controls the pressure pump 132 to work at low power, and water enters the mixing tank 21 through the spray arm 134. The mixing tank weight sensor 213 electrically connected to the automatic control system 4 measures the weight in the mixing tank 21 in real time. When the weight reaches the set parameter, the automatic control system 4 controls the pressure pump 132 to stop working and stop adding water.

[0125] S2: Automatic stirring. When all materials are added, the automatic control system 4 controls the stirring box hopper control valve 2141 to close the stirring box hopper 214, and the automatic control system 4 controls the stirring shaft drive motor 224 to work. The stirring blades 222 stir the materials in the stirring box 21 to mix. When the set time is reached, the automatic control system 4 controls the stirring shaft drive motor 224 to stop working and the stirring stops.

[0126] S3: mold leveling;

[0127] S31: The laser radar 2151 performs automatic leveling detection. When the mixing box discharge door 2152 is closed, the automatic control system 4 controls the laser radar 2151 to scan the four corner points of the forming mold 321 below; if the laser radar 2151 scans the four corner points of the forming mold 321, step S32 is executed, otherwise the position of the forming mold 321 is adjusted until the laser radar 2151 scans the four corner points of the forming mold 321.

[0128] S32: Leveling. The automatic control system 4 calculates the horizontal inclination angle of the plane formed by the four corner points of the molding die 321 according to the distance scanned by the laser radar 2151, and calculates the height adjustment amount of the four leveling screw rods 3132 according to the horizontal inclination angle.

[0129] Step S32 specifically includes the following steps:

[0130] The laser radar 2151 measures the distances from the four corner points A, B, C, and D of the forming mold 321 as dA, dB, dC, and dD, respectively. The position of the laser radar 2151 is the origin O, and the height is set to h. is the pitch angle from the laser radar 2151 to the corner point, is the horizontal azimuth from the LiDAR 2151 to the corner point, then the three-dimensional coordinates of each corner point (xi, yi, zi), i = A, B, C, D, can be calculated by the following formula:

[0131] ;

[0132] ;

[0133] ;

[0134] Choose any three points such as A, B, and C to calculate the plane equation. First calculate two vectors:

[0135] ;

[0136] ;

[0137] Then find the normal vector :

[0138] ;

[0139] ;

[0140] ;

[0141] The plane equation is expressed as:

[0142] ;

[0143] Then determine whether the plane is horizontal. The necessary and sufficient condition for the plane to be horizontal is the normal vector is the vertical direction, that is and , considering the existence of true error, if and , For tolerance, such as 0.001, the plane is level. If it is not level, the heights of the four corner points are corrected.

[0144] The correction value of each corner point is the difference between the current height and the target horizontal plane. The average height of the current plane is calculated as , corrected displacement , positive value means it needs to be raised, negative value means it needs to be lowered, and the height correction values ​​of the four corner points are obtained, that is, the height correction values ​​of the leveling screw nut 3131 、 、 、 .

[0145] Finally, it is set that the moving distance of the leveling screw nut 3131 after the leveling screw 3132 rotates n times is unit 1, so that the automatic control system 4 calculates the number of turns N that the leveling screw 3132 needs to rotate based on the distance that the four leveling screw nuts 3131 need to move in the vertical direction, that is, controls the leveling motor 3133 to drive the leveling screw 3132 to rotate N times.

[0146] S4: pouring;

[0147] During pouring, each mold cavity of the forming mold 321 is filled in sequence, and the automatic control system 4 controls the mixing box discharge door control motor 2153 to drive the mixing box discharge door 2152 to open outward, and the concrete in the mixing box falls into the feeding chute 25 through the mixing box discharge door 2152, and then enters the forming mold 321 through the feeding chute 25. During this process, the automatic control system 4 controls the eccentric vibrator 322 to work, and the laser radar 2151 measures the height of the upper surface of the concrete in the forming mold 321 in real time. When the upper surface of the filled concrete reaches the plane formed by the four corner points of the forming mold 321 initially scanned, the automatic control system 4 controls the mixing box discharge door control motor 2153 to drive the mixing box discharge door 2152 to close, and the pouring is stopped. The eccentric vibrator 322 stops working, and the automatic leveling forming system 3 moves away via the leveling system bottom plate guide rail 3111.

[0148] S5: self-cleaning;

[0149] S51: The stirring device self-cleans, the automatic control system 4 controls the pressure pump 132 to work at full power, the high-pressure water drives the spray arm 134 to rotate, and the water sprayed by the spray arm 134 flushes the stirring box 21, the stirring blade 222 and the stirring scraper 223; the automatic control system 4 controls the stirring shaft drive motor 224 to work, and the stirring blade 222 rotates around the stirring shaft 221.

[0150] S52: The laser radar 2151 detects the cleanliness level, the automatic control system 4 controls the pressure pump 132 and the stirring shaft drive motor 224 to stop working, controls the mixing box discharge door control motor 2153 to drive the mixing box discharge door 2152 to open outward, and discharges sewage, controls the mixing box discharge door control motor 2153 to drive the mixing box discharge door 2152 to rotate into the mixing box 21, and the laser radar 2151 scans several points in the mixing box shell 212. If the distances to several points are consistent with the distances measured when no material is added and the box is empty, it means that the cleaning is completed. If the distance to a certain point is less than the distance measured when no material is added and the box is empty, it means that the cleaning is not thorough, and steps S51-S52 are executed again until the cleaning is completed.

[0151] S6: demoulding;

[0152] The automatic control system 4 controls the rotating platform shaft drive motor 3123 to work, so that the rotating platform shaft 3122 rotates and the rotating platform plate 3121 flips horizontally. The compressed air will pass through the mold one-way valve 323 to push out the solidified test block, and then the rotating platform plate 3121 is reset to complete the demoulding.
