Description

Technical Field

[0001] This invention relates to the field of concrete consistency testing equipment, specifically to a testing device for detecting the consistency of high-grade concrete. Background Technology

[0002] The consistency of concrete is an important indicator of its workability, especially in the application of high-grade concrete, where its workability directly affects construction quality, pumpability, and structural formation. Slump testing, as a widely used method for detecting concrete consistency, is crucial for the accuracy of project quality control and the optimization of construction techniques.

[0003] Currently, conventional slump testing devices mainly consist of a slump cylinder, a base plate, and an auxiliary lifting structure. During the test, the slump cylinder needs to be lifted manually. During operation, the cylinder is prone to tilting or uneven force due to unstable lifting, which affects the uniformity of concrete slump and causes deviations in test results. In addition, high-grade concrete has higher viscosity and is more likely to form a strong adhesion to the inner wall of the slump cylinder, causing the concrete to not completely detach from the cylinder wall during the slump, further affecting the accuracy of the slump value. Summary of the Invention

[0004] The purpose of this invention is to provide a testing device for detecting the consistency of high-grade concrete, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a testing device for detecting the consistency of high-grade concrete, comprising a windproof box, and further comprising: A vibration mechanism is provided inside a windproof box. The vibration mechanism includes a slump cylinder installed inside the windproof box. A placement groove is provided on the top of the windproof box, and a funnel is installed in the placement groove. An annular plate is installed inside the windproof box, and several fixed annular plates are provided on the top of the annular plate. The vibration mechanism is used to drive the slump cylinder to vibrate. A blower mechanism is provided inside a windproof box. The blower mechanism includes a spiral air groove provided on the inner wall of a slump cylinder. A rectangular tube is provided inside the slump cylinder and extends to the outside of the slump cylinder. A corrugated pipe is provided on the rectangular tube. The blower mechanism is used to generate a centrifugal air film during concrete testing. A measuring mechanism is provided, which is mounted on a windproof box. The measuring mechanism includes a feed chute mounted on the windproof box, a rectangular rotating rod inside the windproof box, a circular fixing block on the rectangular rotating rod, and a return spring on the circular fixing block. The measuring mechanism is used to measure the slump value of the concrete being tested.

[0006] Furthermore, the vibration mechanism includes a placement slot on the top of the windproof box, on which a funnel is placed. The funnel is adapted to the slump cylinder. Two adaptation slots are provided on the placement slot. The vibration mechanism also includes a fixed ring plate fixedly installed on the outer wall of the slump cylinder. Several fixed sliding rods slide through the fixed ring plate, and the bottom ends of the several fixed sliding rods are fixedly connected to the ring plate.

[0007] Furthermore, each of the fixed sliding rods is fitted with a limiting spring, the bottom end of each limiting spring is fixedly connected to the annular plate, and the top end of each limiting spring is fixedly connected to the fixed annular plate.

[0008] Furthermore, a connecting plate is fixedly installed on the outer wall of the annular plate, a threaded rod is rotatably installed inside the windproof box, the top end of the threaded rod extends to the outside of the windproof box, a drive motor is fixedly installed on the top end of the threaded rod, the drive motor is fixedly connected to the windproof box, and the threaded rod threaded through the connecting plate.

[0009] Furthermore, a vibrating toothed plate is fixedly installed on the outer wall of the slump cylinder, a fixing frame is fixedly installed inside the windproof box, an installation groove is opened in the fixing frame, an adaptation spring is fixedly installed on the inner right side of the installation groove, a trapezoidal plate is fixedly installed at the right end of the adaptation spring, the trapezoidal plate extends into the vibrating toothed plate, and the vibrating toothed plate is adapted to the adaptation groove.

[0010] Furthermore, the blower mechanism includes a spiral air groove formed on the inner wall of the slump cylinder, and a rectangular tube is fixedly installed inside the slump cylinder, with the end of the rectangular tube extending outside the slump cylinder.

[0011] Furthermore, a corrugated pipe is fixedly installed at the end of the rectangular tube, and a smart fan is fixedly installed on the back of the slump cylinder. The end of the corrugated pipe extends outside the slump cylinder and communicates with the smart fan.

[0012] Furthermore, the front and back sides of the slump cylinder are respectively provided with limiting grooves, and two T-shaped limiting plates are fixedly installed on the outer wall of the annular plate. The two T-shaped limiting plates slide through the two limiting grooves and are respectively adapted to the two limiting grooves.

[0013] Furthermore, the measuring mechanism includes a feed chute opened on the top of the windproof box, a rectangular rotating rod rotatably installed inside the windproof box, a circular fixing block fixedly sleeved on the rectangular rotating rod, and a contact plate rotatably sleeved on the rectangular rotating rod.

[0014] Furthermore, a return spring is sleeved on the rectangular rotating rod, the bottom end of the return spring is fixedly connected to the circular fixing block, the top end of the return spring is fixedly connected to the contact plate, and a measuring value is set on the rectangular rotating rod.

[0015] The present invention has the following beneficial effects: (1) The present invention provides a test device for detecting the consistency of high-grade concrete. During the process of the ring plate driving the fixed sliding rod and the limiting spring to rise, the limiting spring will undergo compression deformation due to the gravity of the fixed ring plate and the slump cylinder. At the same time, the slump cylinder will drive the vibrating tooth plate to rise synchronously. When the vibrating tooth plate rises and contacts the inclined surface of the trapezoidal plate, the trapezoidal plate slides into the installation groove under the action of the inclined surface. When the trapezoidal plate is separated from the tooth groove corresponding to the current vibrating tooth plate, the trapezoidal plate will align with the next tooth groove position during the sliding process and be pushed under the elastic force of the adapting spring, and re-insert into the next tooth groove of the vibrating tooth plate. During this process, as the vibrating tooth plate continues to rise with the slump cylinder and is driven by the compression potential energy of the limiting spring, the trapezoidal plate will collide with the vibrating tooth plate each time it is inserted into a new tooth groove, thereby generating a vibration effect. This vibration helps the concrete particles inside the slump cylinder to fall off the cylinder wall, further improving the separation effect between the concrete and the cylinder wall, and effectively improving the accuracy and reliability of the slump value measurement. (2) The present invention provides a test device for testing the consistency of high-grade concrete. When in use, the windproof box is placed on a clean and flat base plate, and then the funnel is placed in the placement groove and inserted into the slump cylinder. Concrete is poured into the slump cylinder in three layers through the funnel. After each layer is poured, the tamping rod is rotated and tamped 25 times from the outside to the inside to ensure the compactness of the concrete. After all three layers of concrete are filled, the funnel is removed and the excess concrete at the top of the slump cylinder is scraped off. Then the drive motor is started, and the drive motor drives the threaded rod to rotate. The threaded rod drives the connecting plate to rise, and the connecting plate drives the annular plate to rise. At the same time, the annular plate drives the fixed ring plate, the fixed sliding rod and the limiting spring to rise synchronously. The fixed ring plate drives the slump cylinder to rise vertically. During this process, the limiting groove and the T-shaped limiting plate work together to limit the movement and ensure that the slump cylinder rises smoothly and vertically. This avoids the tilting or torque that may occur when the slump cylinder is lifted manually in the traditional way, effectively reducing the measurement deviation of the concrete slump value and improving the accuracy and reliability of the concrete consistency test. (3) The present invention provides a device for testing the consistency of high-grade concrete. Before pouring concrete into the slump cylinder, an intelligent fan is started. The intelligent fan sends gas into the spiral air groove through a corrugated pipe and a rectangular pipe. Under the cyclone effect of the cyclone generator, the airflow rotates and rises along the path of the spiral air groove and under the shape limitation of the slump cylinder. The system first starts a high-pressure pulse air curtain (pressure of 0.8 MPa) for 0.3 seconds to remove any residual particles that may exist on the inner wall of the slump cylinder. Then, a micro airflow of 0.1 MPa is maintained to form a protective layer with an airflow velocity of 2 m / s. During the process of pouring concrete into the slump cylinder, the airflow rising along the spiral air groove will form a uniform centrifugal air film between the cylinder wall and the concrete. At this time, the air pressure is increased to 0.4 MPa to effectively suppress the direct contact between the concrete and the cylinder wall and reduce the friction effect. When lifting the slump cylinder, the pressure is switched to 0.6 MPa. The rotating airflow of MPa and the centrifugal air film further promote the separation effect between the concrete and the inner wall of the slump cylinder, thereby significantly reducing the adhesion of concrete to the cylinder wall and avoiding the impact of concrete residue on the measurement accuracy of slump value. After the concrete has slumped, the air pressure is gradually reduced to the base air pressure in stages. The entire process is divided into three stages to complete the depressurization, ensuring that the system can stably and controllably return to the initial state. (4) The present invention provides a test device for detecting the consistency of high-grade concrete. When the slump cylinder descends and contacts the ground, the rectangular rotating rod is rotated to drive the contact plate to rotate synchronously, so that the bottom of the contact plate contacts the top of the slump cylinder, thereby measuring and confirming the height of the slump cylinder. Then, the rectangular rotating rod is rotated to make the contact plate rotate away from the slump cylinder. After the slump cylinder is lifted, the concrete inside collapses. At this time, the rectangular rotating rod is rotated again to adjust the position of the contact plate and press the contact plate down so that its bottom contacts the highest point of the collapsed concrete, and a second height measurement is performed. By comparing the height difference between the original height of the slump cylinder and the highest point of the collapsed concrete, the slump value of the concrete can be calculated, thereby accurately judging the consistency state of the concrete and completing the test.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-8 As shown, the present invention is a testing device for detecting the consistency of high-grade concrete, including a windproof box 1, and further comprising: The vibration mechanism is installed inside the windproof box 1. The vibration mechanism includes a slump cylinder 101 installed inside the windproof box 1. A placement groove 102 is provided on the top of the windproof box 1. A funnel 103 is provided in the placement groove 102. An annular plate 104 is provided inside the windproof box 1. Several fixed annular plates 105 are provided on the top of the annular plate 104. The vibration mechanism is used to generate vibration of the slump cylinder 101. The blower mechanism is installed inside the windproof box 1. The blower mechanism includes a spiral air groove 2 installed on the inner wall of the slump cylinder 101. A rectangular tube 201 is installed inside the slump cylinder 101 and extends to the outside of the slump cylinder 101. A corrugated tube 202 is installed on the rectangular tube 201. The blower mechanism is used to generate a centrifugal air film during concrete testing. The measuring mechanism is set on the windproof box 1. The measuring mechanism includes a feed chute 3 set on the windproof box 1, a rectangular rotating rod 301 set inside the windproof box 1, a circular fixing block 302 set on the rectangular rotating rod 301, and a return spring 303 set on the circular fixing block 302. The measuring mechanism is used to measure the slump value of the concrete being tested.

[0022] like Figure 1 , Figure 2 and Figure 4 As shown, the vibration mechanism includes a placement groove 102 on the top of the windproof box 1, a funnel 103 placed on the placement groove 102, the funnel 103 being adapted to the slump cylinder 101, and two adaptation grooves on the placement groove 102. The vibration mechanism also includes a fixed ring plate 105 fixedly installed on the outer wall of the slump cylinder 101, and a plurality of fixed sliding rods 106 sliding through the fixed ring plate 105, the bottom ends of the plurality of fixed sliding rods 106 being fixedly connected to the ring plate 104.

[0023] Place the windproof box 1 on a clean and flat base plate, then put the funnel 103 into the placement groove 102 and into the slump cylinder 101. Pour concrete into the slump cylinder 101 in three layers through the funnel 103. After each layer is poured, use a tamping rod to rotate and tamp it 25 times from the outside to the inside to ensure the compactness of the concrete. After all three layers of concrete are filled, remove the funnel 103 and scrape the excess concrete on the top of the slump cylinder 101.

[0024] like Figure 4 As shown, a number of fixed sliding rods 106 are respectively fitted with limiting springs 107, the bottom ends of the limiting springs 107 are fixedly connected to the annular plate 104, and the top ends of the limiting springs 107 are fixedly connected to the fixed annular plate 105.

[0025] During the process of the annular plate 104 driving the fixed slide bar 106 and the limiting spring 107 to rise, the limiting spring 107 will undergo compression deformation due to the gravity of the fixed annular plate 105 and the slump cylinder 101.

[0026] like Figure 3 and Figure 4 As shown, a connecting plate 108 is fixedly installed on the outer wall of the annular plate 104, and a threaded rod 109 is rotatably installed inside the windproof box 1. The top end of the threaded rod 109 extends to the outside of the windproof box 1, and a drive motor 110 is fixedly installed on the top end of the threaded rod 109. The drive motor 110 is fixedly connected to the windproof box 1, and the threaded rod 109 threadedly passes through the connecting plate 108.

[0027] Then, the drive motor 110 is started, which drives the threaded rod 109 to rotate. The threaded rod 109 drives the connecting plate 108 to rise, and the connecting plate 108 drives the annular plate 104 to rise. At the same time, the annular plate 104 drives the fixed annular plate 105, the fixed slide rod 106, and the limit spring 107 to rise synchronously.

[0028] like Figure 3 , Figure 5 and Figure 6 As shown, a vibrating toothed plate 115 is fixedly installed on the outer wall of the slump cylinder 101, and a fixing frame 111 is fixedly installed inside the windproof box 1. An installation groove 112 is opened in the fixing frame 111. An adaptation spring 113 is fixedly installed on the inner right side of the installation groove 112. A trapezoidal plate 114 is fixedly installed at the right end of the adaptation spring 113. The trapezoidal plate 114 extends into the vibrating toothed plate 115, and the vibrating toothed plate 115 is adapted to the adaptation groove.

[0029] The slump cylinder 101 drives the vibrating toothed plate 115 to rise synchronously. When the vibrating toothed plate 115 rises and contacts the inclined surface of the trapezoidal plate 114, the trapezoidal plate 114 slides into the mounting groove 112 under the action of the inclined surface. When the trapezoidal plate 114 disengages from the corresponding tooth groove of the current vibrating toothed plate 115, the trapezoidal plate 114 will align with the position of the next tooth groove during the sliding process, and will be pushed by the elastic force of the adapting spring 113, and re-enter into the next tooth groove of the vibrating toothed plate 115. During this process, as the vibrating toothed plate 115 continues to rise with the slump cylinder 101, and driven by the compressive potential energy of the limiting spring 107, the trapezoidal plate 114 will collide with the vibrating toothed plate 115 each time it is inserted into a new tooth groove, thereby generating a vibration effect. This vibration helps the concrete particles inside the slump cylinder 101 to fall off the cylinder wall, further improving the separation effect between the concrete and the cylinder wall, and effectively improving the accuracy and reliability of the slump value measurement.

[0030] like Figure 7As shown, the blower mechanism includes a spiral air groove 2 formed on the inner wall of the slump cylinder 101, and a rectangular tube 201 is fixedly installed inside the slump cylinder 101, with the end of the rectangular tube 201 extending to the outside of the slump cylinder 101.

[0031] Under the cyclone effect of the cyclone generator, the airflow rotates and rises along the path of the spiral air groove 2 and under the shape limitation of the slump cylinder 101. The system first starts a high-pressure pulse air curtain with a pressure of 0.8 MPa for 0.3 seconds to remove any residual particles that may exist on the inner wall of the slump cylinder 101. Then, a micro airflow of 0.1 MPa is maintained to form a protective layer with an airflow velocity of 2 m / s. During the process of pouring concrete into the slump cylinder 101, the airflow rising along the spiral air groove 2 will form a uniform centrifugal air film between the cylinder wall and the concrete. At this time, the air pressure is increased to 0.4 MPa to effectively suppress the direct contact between the concrete and the cylinder wall and reduce the friction effect. When lifting the slump cylinder 101, the airflow is switched to a rotating airflow of 0.6 MPa. The centrifugal air film further promotes the separation effect between the concrete and the inner wall of the slump cylinder 101, thereby significantly reducing the adhesion of concrete to the cylinder wall.

[0032] like Figure 7 As shown, a corrugated pipe 202 is fixedly installed at the end of the rectangular tube 201, and a smart fan 203 is fixedly installed on the back of the slump cylinder 101. The end of the corrugated pipe 202 extends outside the slump cylinder 101 and communicates with the smart fan 203.

[0033] Before pouring concrete into the slump cylinder 101, the intelligent fan 203 is started. The intelligent fan 203 sends gas into the spiral air trough 2 through the corrugated pipe 202 and the rectangular pipe 201.

[0034] like Figure 1 , Figure 6 and Figure 7 As shown, limit grooves 204 are respectively opened on the front and back of the slump cylinder 101. Two T-shaped limit plates 205 are fixedly installed on the outer wall of the annular plate 104. The two T-shaped limit plates 205 slide through the two limit grooves 204 and are respectively adapted to the two limit grooves 204.

[0035] The fixed ring plate 105 drives the slump cylinder 101 to rise vertically. During this process, the limiting groove 204 and the T-shaped limiting plate 205 work together to limit the movement, ensuring that the slump cylinder 101 rises smoothly and vertically. This avoids the tilting or torque that may occur when the slump cylinder 101 is lifted manually in the traditional way, effectively reducing the measurement deviation of the concrete slump value and improving the accuracy and reliability of the concrete consistency test.

[0036] like Figure 2 and Figure 8As shown, the measuring mechanism includes a feed chute 3 opened on the top of the windproof box 1, a rectangular rotating rod 301 rotatably installed inside the windproof box 1, a circular fixing block 302 fixedly sleeved on the rectangular rotating rod 301, and a contact plate 304 rotatably sleeved on the rectangular rotating rod 301.

[0037] When the slump cylinder 101 descends and contacts the ground, the contact plate 304 is rotated synchronously by rotating the rectangular rotating rod 301, so that the bottom of the contact plate 304 contacts the top of the slump cylinder 101, thereby measuring and confirming the height of the slump cylinder 101. Then, the rectangular rotating rod 301 is rotated so that the contact plate 304 is rotated to a direction away from the slump cylinder 101.

[0038] like Figure 8 As shown, a return spring 303 is sleeved on the rectangular rotating rod 301. The bottom end of the return spring 303 is fixedly connected to the circular fixing block 302, and the top end of the return spring 303 is fixedly connected to the contact plate 304. A metering value 305 is provided on the rectangular rotating rod 301.

[0039] After the slump cone 101 is lifted, the concrete inside collapses. At this time, the rectangular rotating rod 301 is rotated again to adjust the position of the contact plate 304 and press the contact plate 304 down so that its bottom contacts the highest point of the collapsed concrete. A second height measurement is then performed. By comparing the original height of the slump cone 101 with the height difference of the highest point of the collapsed concrete, the slump value of the concrete can be calculated, thereby accurately determining the consistency of the concrete and completing the test.

[0040] In use, place the windproof box 1 on a clean and flat base plate, then place the funnel 103 into the placement groove 102 and extend it into the slump cone 101. Pour concrete into the slump cone 101 in three layers through the funnel 103. After each layer is poured, use a tamping rod to rotate and tamp the concrete 25 times from the outside to the inside to ensure the compactness of the concrete. After all three layers of concrete are poured, remove the funnel 103 and scrape off any excess concrete from the top of the slump cone 101. Then start the drive motor 110, which drives the threaded rod 109. Rotation causes the threaded rod 109 to drive the connecting plate 108 to rise, which in turn drives the annular plate 104 to rise. Simultaneously, the annular plate 104 drives the fixed annular plate 105, the fixed sliding rod 106, and the limiting spring 107 to rise synchronously. The fixed annular plate 105 drives the slump cylinder 101 to rise vertically. During this process, the limiting groove 204 and the T-shaped limiting plate 205 work together to limit the movement, ensuring that the slump cylinder 101 rises smoothly and vertically, thus avoiding the tilting or torque that may occur when the slump cylinder 101 is lifted manually in the traditional way. Before pouring concrete into the slump cylinder 101, the intelligent fan 203 is activated. The intelligent fan 203 sends gas into the spiral air channel 2 through the corrugated pipe 202 and rectangular pipe 201. Under the cyclone effect of the cyclone generator, the airflow rotates and rises along the path of the spiral air channel 2, constrained by the shape of the slump cylinder 101. The system first activates a high-pressure pulse air curtain with a pressure of 0.8 MPa for 0.3 seconds to remove any residual particles that may be present on the inner wall of the slump cylinder 101. Subsequently, a micro-airflow of 0.1 MPa is maintained to form a protective layer with an airflow velocity of 2 m / s. During the pouring of concrete into the slump cylinder 101, the airflow rising along the spiral air channel 2 forms a uniform centrifugal air film between the cylinder wall and the concrete. At this point, the air pressure is increased to 0.4 MPa to effectively suppress direct contact between the concrete and the cylinder wall and reduce friction. When lifting the slump cylinder 101, the pressure is switched to 0.6 MPa. The rotating airflow of MPa and the centrifugal air film further promote the separation effect between the concrete and the inner wall of the slump cylinder 101, thereby significantly reducing the adhesion of concrete to the cylinder wall and avoiding the impact of concrete residue on the measurement accuracy of slump value. After the concrete has slumped, the air pressure is gradually reduced to the base air pressure in stages. During the upward movement of the annular plate 104, which drives the fixed slide rod 106 and the limiting spring 107, the limiting spring 107 undergoes compression deformation due to the gravity of the fixed annular plate 105 and the slump cylinder 101. Simultaneously, the slump cylinder 101 drives the vibrating toothed plate 115 to rise synchronously. When the vibrating toothed plate 115 rises and contacts the inclined surface of the trapezoidal plate 114, the trapezoidal plate 114 slides into the mounting groove 112 under the action of the inclined surface. Once the trapezoidal plate 114 disengages from the corresponding tooth groove of the current vibrating toothed plate 115, the trapezoidal plate... During the sliding process, the trapezoidal plate 114 will align with the next toothed groove and be pushed by the elastic force of the adapting spring 113, and re-engage into the next toothed groove of the vibrating toothed plate 115. During this process, as the vibrating toothed plate 115 continues to rise with the slump cylinder 101, and driven by the compressive potential energy of the limiting spring 107, the trapezoidal plate 114 will collide with the vibrating toothed plate 115 each time it engages in a new toothed groove, thereby generating a vibration effect. This vibration helps the concrete particles inside the slump cylinder 101 to fall off the cylinder wall. When the slump cone 101 descends and contacts the ground, the rectangular rotating rod 301 is rotated, causing the contact plate 304 to rotate synchronously, so that the bottom of the contact plate 304 contacts the top of the slump cone 101, thereby measuring and confirming the height of the slump cone 101. Then, the rectangular rotating rod 301 is rotated so that the contact plate 304 is rotated away from the slump cone 101. After the slump cone 101 is lifted, the concrete inside collapses. At this time, the rectangular rotating rod 301 is rotated again to adjust the position of the contact plate 304, and the contact plate 304 is pressed down so that its bottom contacts the highest point of the collapsed concrete, and a second height measurement is performed. By comparing the original height of the slump cone 101 with the height difference of the highest point of the collapsed concrete, the slump value of the concrete can be calculated.
