Abstract
Description
Technical Field
[0001] This utility model relates to the field of detection device technology, and in particular to a concrete slump detection device. Background Technology
[0002] Concrete slump mainly refers to the plasticizing and pumpability properties of concrete. Factors affecting concrete slump include changes in gradation, water content, weighing deviation of the weighing instrument, and the amount of admixtures. Often overlooked factors include cement temperature. Concrete is one of the most important civil engineering materials in modern times. It is an artificial stone material made by mixing cementitious materials, granular aggregates (also called aggregates), water, and, when necessary, admixtures and additives in a certain proportion, uniformly mixing, compacting, and curing. Concrete is characterized by abundant raw materials, low price, and simple production process, leading to its increasing use. Concrete also has high compressive strength, good durability, and a wide range of strength grades. Before use, concrete slump testing is often necessary.
[0003] An existing concrete slump testing device (announcement number: CN221804009U) has at least the following drawbacks:
[0004] In the aforementioned patent, a support plate is used to support the second servo motor, transmission rod, and first servo motor, enabling the vibration and bucket lifting operations to be completed. However, the top space of the slump bucket is relatively small, and the presence of transmission rods and mixing rods inside makes it inconvenient to add concrete to the slump bucket. Furthermore, after the concrete collapses, the support plate and other components obstruct the view, making it inconvenient to operate the measuring ruler for height detection. This makes the system inconvenient to use and presents certain limitations. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a concrete slump testing device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A concrete slump testing device includes a testing platform with a tamping rod on its top surface, a slump bucket for testing concrete slump, a feeding assembly for feeding the slump bucket, the feeding assembly including a fixing pipe fixedly installed on the top surface of the testing platform, a rotating top frame movably fitted onto the inner circular wall of the fixing pipe, a guide hopper fixedly installed on one side of the rotating top frame, a moving assembly for moving the slump bucket, a measuring assembly for testing the height of the concrete after slump, a cleaning assembly for facilitating concrete cleaning, and a leveling assembly for adjusting the levelness of the testing platform.
[0008] As a further embodiment of this utility model, the movable component includes: a support base frame, which is movably sleeved on the outer circular wall of the fixed tube. A limiting groove is formed on the bottom surface of the support base frame, and a first limiting plate is movably sleeved inside the limiting groove. A first threaded hole is formed on the top surface of the first limiting plate, and a first threaded post is threadedly connected to the inner circular wall of the first threaded hole.

The bearing is fixedly sleeved with the first threaded post, and a hand crank is fixedly installed on the top surface of the first threaded post.
[0009] As a further embodiment of this utility model, the measuring component includes: a support frame, which is fixedly installed on the top surface of the rotating top frame. The top surface of the support frame has a first circular through hole. A movable column is movably sleeved on the inner circular wall of the first circular through hole. The outer circular wall of the movable column has a scale. A spring is movably sleeved on the outer circular wall of the movable column. The top surface of the rotating top frame has a limit hole. A support tube is movably sleeved on the inner circular wall of the limit hole. The support tube is movably sleeved with the movable column. A fixing plate is fixedly installed on the bottom surface of the support tube. A fixing column is fixedly installed on the outer circular wall of the support tube.
[0010] As a further embodiment of this utility model, the cleaning component includes: a movable disk, which is disposed on the top surface of the testing platform, a fixing groove is provided on the top surface of the testing platform, and a second limiting plate is fixedly installed on the outer circular wall surface of the testing platform.
[0011] As a further embodiment of this utility model, the horizontal adjustment component includes: a plurality of second threaded holes, all of which are formed on the top surface of the testing platform, and a second threaded post is threadedly connected to the inner circular wall of the second threaded hole, and a circular level bubble is provided on the top surface of the rotating top frame.
[0012] As a further embodiment of this utility model, rotating rings are fixedly installed on the outside of both the supporting base and the rotating top frame.
[0013] As a further embodiment of this utility model, a limit ring is fixedly sleeved on the outer circular wall surface of the fixed tube.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. Through the coordinated use of the detection platform, slump bucket, tamping rod, fixing pipe, rotating top frame, and guide hopper, the system facilitates the loading of materials into the slump bucket. The top space of the guide hopper is ample for easy loading. Height measurement can be completed by pressing down the spring and moving the support pipe and fixing plate, making it convenient to use. At the same time, rotating the hand crank and the first threaded column prevents the slump bucket from tilting during upward movement. When pouring concrete into the slump bucket, it can be limited to prevent it from moving up or down, making it convenient to use and quite practical.
[0016] 2. By using the set circular level bubble, when the user needs to test the slump of the concrete, by observing the circular level bubble, the second threaded column is manually turned inside the second threaded hole to rotate the second threaded column up and down, thereby adjusting the horizontal angle of the test platform. The rotating ring is manually pushed to rotate, which drives the rotating top frame and the guide hopper to rotate, which facilitates the rotation operation. Attached Figure Description

[0027] Reference Figures 1-6A concrete slump testing device includes a testing platform 1 with a tamping rod 3 mounted on its top surface. It also includes a slump bucket 2 for testing the concrete slump, a feeding assembly for feeding the slump bucket 2, comprising a fixing pipe 4 fixedly installed on the top surface of the testing platform 1, a rotating top frame 5 movably fitted onto the inner circular wall of the fixing pipe 4, and a guide hopper 6 fixedly installed on one side of the rotating top frame 5, a moving assembly for moving the slump bucket 2, a measuring assembly for measuring the height of the concrete after slump, a cleaning assembly for facilitating concrete cleaning, and a leveling adjustment assembly. The adjustment component is used to adjust the levelness of the testing platform 1. The moving component includes: a support base 14, which is movably sleeved on the outer circular wall of the fixed tube 4. A limit groove 15 is opened on the bottom surface of the support base 14. A first limit plate 16 is movably sleeved inside the limit groove 15. A first threaded hole 17 is opened on the top surface of the first limit plate 16. A first threaded post 18 is threadedly connected to the inner circular wall of the first threaded hole 17. A second circular through hole is opened on the top surface of the support base 14. A bearing 19 is fixedly sleeved on the inner circular wall of the second circular through hole. The bearing 19 is fixedly sleeved with the first threaded post 18. A hand crank 20 is fixedly installed on the top surface of the first threaded post 18.
[0028] In use, rotating the rotating ring 28 drives the rotating top frame 5 and the guide hopper 6 to rotate, so that the guide hopper 6 is above the slump bucket 2, thereby adding concrete into the slump bucket 2 through the guide hopper 6. Then, rotating the guide hopper 6 about 180 degrees ensures that the relevant components do not interfere with the compaction operation. Then, the compaction rod 3 can be picked up to compact. Generally, concrete is added in three times and compacted three times. After compaction, manually rotating the hand crank 20 drives the first threaded column 18 to rotate, so that the first threaded column 18 and the first threaded hole 17 convert the rotational motion into linear motion. The bearing 19 supports the first threaded column 18, thereby causing the first limiting plate 16 to move upward, which in turn moves the slump bucket 2 upward, thereby gradually separating the slump bucket 2 from the concrete. Then, the concrete will collapse under the action of gravity, and subsequent measurement work can be carried out.
[0029] In this embodiment, the measuring component includes: a support frame 7, which is fixedly installed on the top surface of the rotating top frame 5. The top surface of the support frame 7 has a first circular through hole. A movable column 8 is movably sleeved on the inner circular wall of the first circular through hole. The outer circular wall of the movable column 8 has a scale. A spring 9 is movably sleeved on the outer circular wall of the movable column 8. A limit hole 10 is opened on the top surface of the rotating top frame 5. A support tube 11 is movably sleeved on the inner circular wall of the limit hole 10. The support tube 11 is movably sleeved with the movable column 8. A fixing plate 12 is fixedly installed on the bottom surface of the support tube 11. A fixing column 13 is fixedly installed on the outer circular wall of the support tube 11. The cleaning component includes: a movable disk 21, which is disposed on the top surface of the detection table 1. A fixing groove 23 is opened on the top surface of the detection table 1. A second limit plate 22 is fixedly installed on the outer circular wall of the detection table 1.
[0030] During use, the concrete collapses under gravity. Simultaneously, the rotating support base 14 is moved away, and then the rotating top frame 5 is rotated back. Holding the fixed column 13, the support tube 11 is rotated, causing the fixed plate 12 to rotate, so that the fixed plate 12 is at the top of the concrete. Then, the moving column 8 is pressed down to compress the spring 9, so that the bottom of the moving column 8 contacts the moving plate 21. The moving column 8 has a scale on its outside. Then, the moving support tube 11 drives the fixed plate 12 to rotate and adjust, so that the bottom surface of the fixed plate 12 is at the highest point of the concrete. Thus, by visually observing the position of the bottom surface of the fixed plate 12 on the scale outside the moving column 8, the height of the concrete after collapse can be obtained. After the measurement is completed, the moving column 8 is released, and the support tube 11 and the fixed plate 12 are moved upward and reset under the push of the spring 9. Then, the palm is placed inside the second threaded column 25 to lift the edge of the moving plate 21, lift the moving plate 21, and clean away the concrete. The moving plate 21 is positioned by the set second limit plate 22.
[0031] In this embodiment, the horizontal adjustment component includes: a plurality of second threaded holes 24, all of which are opened on the top surface of the testing table 1; a second threaded post 25 is threadedly connected to the inner circular wall of the second threaded hole 24; a circular spirit level 27 is provided on the top surface of the rotating top frame 5; a rotating ring 28 is fixedly installed on the outside of both the supporting base frame 14 and the rotating top frame 5; and a limit ring 26 is fixedly sleeved on the outer circular wall of the fixed tube 4.
[0032] In use, by observing the circular level bubble 27, when the user needs to test the slump of the concrete, the second threaded column 25 is manually turned inside the second threaded hole 24 to rotate the second threaded column 25, thereby moving the second threaded column 25 up and down, and thus adjusting the horizontal angle of the test platform 1. The rotating ring 28 is manually pushed to rotate, which drives the rotating top frame 5 and the guide hopper 6 to rotate, which facilitates the rotation operation.
[0033] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: By using the circular level bubble 27, when the user needs to test the concrete slump, by observing the circular level bubble 27, the user manually rotates the second threaded post 25 inside the second threaded hole 24, causing the second threaded post 25 to move up and down, thereby adjusting the horizontal angle of the testing platform 1. At this time, rotating the rotating ring 28 drives the rotating top frame 5 and the guide hopper 6 to rotate, so that the guide hopper 6 is positioned above the slump bucket 2, thereby adding concrete into the slump bucket 2 through the guide hopper 6. Then, rotating the guide hopper 6 approximately 180 degrees... The components will not interfere with the tamping operation. Therefore, simply pick up the tamping rod 3 to begin tamping. Concrete is typically added in three stages, and tamped three times. After tamping, manually rotate the hand crank 20 to rotate the first threaded post 18, converting the rotational motion of the first threaded post 18 and the first threaded hole 17 into linear motion. The bearing 19 supports the first threaded post 18, causing the first limiting plate 16 to move upwards, which in turn moves the slump bucket 2 upwards, gradually separating the slump bucket 2 from the concrete. The concrete then collapses under gravity. Simultaneously, rotate the support base 14 to move it away, and then rotate the rotating top frame 5 back. Hold the fixing post 13... The support tube 11 rotates, causing the fixed plate 12 to rotate, so that the fixed plate 12 is at the top of the concrete. Then, the moving column 8 is pressed down to compress the spring 9, so that the bottom of the moving column 8 contacts the moving plate 21. The moving column 8 has a scale on its outside. Then, the moving support tube 11 drives the fixed plate 12 to rotate and move, so that the bottom surface of the fixed plate 12 is at the highest point of the concrete. Thus, by visually observing the position of the bottom surface of the fixed plate 12 on the scale on the outside of the moving column 8, the height of the concrete after collapse can be obtained. After the measurement is completed, the moving column 8 is released. Under the push of the spring 9, the support tube 11 and the fixed plate 12 move upward and reset. Then, the palm is placed inside the second threaded column 25. The edge of the movable plate 21 can be lifted to remove the concrete. The movable plate 21 is positioned by the second limiting plate 22, thus achieving the effect of facilitating the filling of the slump bucket 2 by the user. The top space of the guide hopper 6 is sufficient for filling. The height can be measured by the pressure spring 9, the movable support tube 11 and the fixing plate 12, which is convenient for use. At the same time, by turning the hand crank 20 and the first threaded column 18, the slump bucket 2 will not tilt during the upward movement, and when concrete is poured into the slump bucket 2, it can be limited to prevent it from moving, which is convenient for use and quite practical.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
