Abstract
Description
Technical Field
[0001] This utility model relates to the field of workability measurement technology for self-compacting concrete, specifically to a device for measuring the workability of continuous self-compacting concrete. Background Technology
[0002] The success of self-compacting concrete preparation depends primarily on its workability. After mixing the self-compacting concrete, the fresh concrete needs to be tested for segregation resistance, fluidity, and filling properties. Only after the workability meets the standards can it be sent to the curing chamber for further testing.
[0003] Common testing methods for concrete flowability include the slump flow test and the J-ring flow test. This module typically includes a test platform and corresponding measuring tools. When using the slump flow test, the test platform is a circular flat plate. After the concrete flows into the plate from the feeding system, it naturally spreads out. By measuring the diameter of the spread concrete, its flowability can be assessed.
[0004] Existing measuring devices for concrete flowability typically use a funnel-shaped feed cylinder to deliver the concrete to the surface of a circular plate. However, segregation is prone to occur during concrete storage, leading to uneven composition and affecting flowability testing. Furthermore, self-compacting concrete possesses a certain velocity and kinetic energy during discharge; direct discharge to the receiving area generates significant impact on the circular plate. Prolonged exposure to such impacts can cause wear and cracking, reducing the equipment's lifespan. To address this issue, we propose a continuous self-compacting concrete workability measuring device. Summary of the Invention

[0007] Preferably, the control assembly further includes a rotating component, which includes a moving block. The surface of the moving block is fixedly connected to the surface of the slide rod, and the surface of the moving block is fixedly connected to one end of a spring.

[0008] Preferably, an arc plate is fixedly installed on the surface of the movable block, and a knocking block is fixedly installed on the inner wall of the arc plate. When the movable block moves, the arc plate can drive the knocking block to move laterally on the surface of the support plate.
[0009] Preferably, a vertical rod is fixedly installed on the surface of the movable block, and the surface of the vertical rod is fixedly connected to one end of the second spring. The other end of the second spring is fixedly installed on the surface of the support frame. When the movable block moves, the vertical rod can slide under the support of the second spring.
[0010] Preferably, the support frame is penetrated by a support block and slidably connected to the support block, the surface of the support block is fixedly connected to the surface of the vertical rod, and when the support block moves within the support frame, the vertical rod fixed to the surface of the support block slides synchronously.
[0011] Preferably, a motor is fixedly mounted on the surface of the support frame, the output shaft of the motor is fixedly connected to the surface of the reciprocating lead screw, and a stirring rod is fixedly mounted on the surface of the reciprocating lead screw. The output shaft of the motor can drive the reciprocating lead screw and the stirring rod to perform circular motion in the feed tank.
[0012] Preferably, the reciprocating lead screw passes through the moving ring and is threadedly connected to the moving ring. A pressure rod is fixedly installed on the surface of the moving ring.

[0013] Compared with the prior art, this utility model provides a device for measuring the workability of continuous self-compacting concrete, which has the following advantages:
[0014] 1. This continuous self-compacting concrete workability measuring device, through the setting of control components, when the support block is abutted, the vertical rod fixed on the surface of the support block will drive the moving block to slide on the surface of the support plate under the support of spring two. When the moving block moves, the sliding rod fixed on the surface of the moving block slides in the arc groove opened on the surface of the round rod. The round rod is subjected to force to drive the buffer plate to swing. Since the moving block is performing lateral reciprocating motion, the buffer plate can swing continuously at the bottom of the discharge pipe to buffer the impact force of the discharged concrete and avoid the round plate from breaking or being damaged due to excessive impact force.

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: a continuous self-compacting concrete workability measuring device, including a measuring platform 1, a circular plate 2 fixedly mounted on the surface of the measuring platform 1, a fixing rod 3 fixedly mounted on the surface of the measuring platform 1, the fixing rod 3 passing through and fixedly connected to the fixing plate 4, a support plate 5 fixedly mounted on the surface of the fixing rod 3, a feed tank 6 fixedly mounted on the surface of the support plate 5, a support frame 7 fixedly mounted on the surface of the support plate 5, and a buffer control component 8 provided on the surface of the support plate 5. The control component 8 includes: a buffer plate 81, a circular rod 82 fixedly mounted on the surface of the buffer plate 81, and the circular rod 82... The circular rod 82 passes through and is rotatably connected to the support column 83. The support column 83 is fixedly installed on the surface of the fixed plate 4. The surface of the circular rod 82 is provided with an arc-shaped groove 84, which is slidably connected to the sliding rod 85. The sliding rod 85 passes through and is slidably connected to the support column 83. The sliding rod 85 passes through and is slidably connected to the support plate 5. When the circular rod 82 is subjected to force, it drives the buffer plate 81 to swing. Since the moving block 861 performs lateral reciprocating motion, the buffer plate 81 can swing continuously at the bottom of the discharge pipe to buffer the impact force of the discharged concrete and avoid the circular plate 2 from breaking or being damaged due to excessive impact force.
[0022] The control assembly 8 also includes a rotating component 86, which comprises: a movable block 861, the surface of which is fixedly connected to the surface of the slide rod 85, and the surface of which is fixedly connected to one end of a first spring 862. The other end of the first spring 862 is fixedly mounted on the inner wall of the support plate 5. When the movable block 861 moves, it can compress the first spring 862. An arc plate 863 is fixedly mounted on the surface of the movable block 861, and a knocking block 864 is fixedly mounted on the inner wall of the arc plate 863. When the movable block 861 moves, the arc plate 863 can drive the knocking block 864 to move laterally on the surface of the support plate 5. A vertical rod 865 is fixedly mounted on the surface of the movable block 861, the surface of which is fixedly connected to one end of a second spring 866. The other end of the second spring 866 is fixedly mounted on the surface of the support frame 7. When the movable block 861 moves, the vertical rod 865 can slide under the support of the second spring 866. The support frame 7 is penetrated by and slidably connected to the support block 867. The surface of the support block 867 is fixedly connected to the surface of the vertical rod 865. When the support block 867 moves within the support frame 7, the vertical rod 865 fixed to the surface of the support block 867 slides synchronously. A motor 8612 is fixedly mounted on the surface of the support frame 7. The output shaft of the motor 8612 is fixedly connected to the surface of the reciprocating lead screw 8610. A stirring rod 8611 is fixedly mounted on the surface of the reciprocating lead screw 8610. The output shaft of the motor 8612 can drive the reciprocating lead screw 8610 and the stirring rod 8611 to perform circular motion within the feed tank 6. The reciprocating screw 8610 passes through the moving ring 869 and is threadedly connected to the moving ring 869. A pressure rod 868 is fixedly installed on the surface of the moving ring 869. The pressure rod 868 is in contact with the inner wall of the support frame 7. When the reciprocating screw 8610 rotates, the moving ring 869 can move longitudinally, and the pressure rod 868 fixed on the surface of the moving ring 869 slides synchronously on the surface of the support frame 7.
[0023] In this invention, during use, the concrete to be tested is placed into the material tank 6. After placement, the motor 8612 on the surface of the support frame 7 is started. The output shaft of the motor 8612 drives the reciprocating screw 8610 to rotate. The stirring rod 8611 fixed on the surface of the reciprocating screw 8610 stirs the raw material in the material tank 6. After stirring, the concrete in the material tank 6 is discharged through the valve at the bottom of the discharge pipe. During the discharge process, the stirring rod 8611 continues to rotate. When the stirring rod 8611 rotates, the reciprocating screw 8610 rotates synchronously, and the moving ring 869 moves longitudinally. When the pressure rod 868 fixed on the surface of the moving ring 869 moves downward, it will abut against the tangential surface of the support block 867. When the support block 867 is abutted, the vertical rod 865 fixed on the surface of the support block 867 will be supported by the spring 866, causing the moving block 861 to slide on the surface of the support plate 5. When the moving block 861 moves, the vertical rod 865 fixed on the surface of the moving block 861 will abut against the tangential surface of the support plate 5. The fixed sliding rod 85 slides within the arc-shaped groove 84 on the surface of the round rod 82. The round rod 82, under force, drives the buffer plate 81 to swing. Since the moving block 861 performs lateral reciprocating motion, the buffer plate 81 can continuously swing at the bottom of the discharge pipe to buffer the impact force of the discharged concrete, preventing the round plate 2 from breaking or being damaged due to excessive impact force. When the moving block 861 slides on the surface of the support plate 5, the arc plate 863 fixed on the surface of the moving block 861 can move synchronously. The tapping block 864 fixed on the inner wall of the arc plate 863 can continuously tap the surface of the feed tank 6 during the lateral movement, so that the concrete material in the tank can quickly fall off the inner wall of the tank, avoiding discharge blockage and material sticking, thus preventing material waste. The discharged material falls into the round plate 2. The round plate 2 is circular in shape, and the concrete can spread naturally on the round plate 2. By measuring the diameter of the spread concrete, its fluidity can be evaluated.
[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
