Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a slump detection device for engineering testing. Background Technology

[0002] A slump tester for engineering testing is an instrument used to measure the slump of concrete. By quantifying the flowability, cohesiveness, and water retention of concrete, the slump tester helps engineers assess whether the concrete is easy to work with and whether it is uniformly compacted. The device typically includes accessories such as a standard slump cone, a tamping rod, a ruler, and a trowel. In use, a concrete sample is placed into the slump cone, tamped down, and then the cone is lifted vertically. The difference in height between the slump cone and the tamping point is the slump value.

[0003] In existing technologies, most slump testing devices for engineering testing require manual stirring of the raw materials inside the device during use. However, manual stirring requires operators to exert more physical strength, which can easily lead to fatigue and affect work efficiency over a long period of time. Therefore, a slump testing device for engineering testing is proposed to solve the above problems. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1 to 3 This utility model provides an embodiment of a slump testing device for engineering testing, comprising a base plate 1 and a slump tower 2. The base plate 1 provides support to the slump tower 2, enabling stable placement of concrete inside the slump tower 2. The bottom side of the base plate 1 contacts the top side of the slump tower 2, and multiple casters are fixedly connected to the bottom side of the base plate 1, facilitating its movement to different positions. Support legs 3 are fixedly connected to both the left and right ends of the top side of the base plate 1, and handles are fixedly connected to the opposite sides of the two support legs 3. The support force provided to the support legs 3 and the handles are used to rotate and pull the support legs 3. A drive assembly for driving subsequent components is fixedly connected to the inner wall of the right end of the base plate 1. The drive assembly includes a motor 4, which is externally fixedly connected to the inner wall of the right end of the base plate 1. By fixing the motor 4, the motor 4 can operate stably as a drive source.

[0032] A rotating shaft 5 is fixedly connected to the drive end of motor 4, transmitting the rotational force of motor 4 to subsequent components. A driven shaft 6 is rotatably connected to the left end of base plate 1, allowing it to rotate stably by restricting its movement. A drive wheel 7 is fixedly connected to the outside of the drive assembly, with the rotating shaft 5 externally fixed to the inner wall of the drive wheel 7. A belt 8 is fitted around the outside of the drive wheel 7, transmitting rotational force to the drive wheel 7 via the rotating shaft 5. The drive wheel 7 then transmits the force to the belt 8, which in turn transmits the power to subsequent components. A driven wheel 9 is fixedly connected to the outside of the driven shaft 6, with the driven wheel 9 fitted inside the belt 8. After receiving the force from the belt 8, the driven wheel 9 transmits the rotational force to the driven shaft 6, causing it to rotate.

[0033] Both the drive assembly and the driven shaft 6 have a circular plate 10 fixedly connected to their top ends. The top end of the driven shaft 6 is fixedly connected to the inner wall of one of the circular plates 10. A rotating column 11 is fixedly connected to the top side of the circular plate 10. The driven shaft 6 and the rotating shaft 5 drive the circular plate 10 to rotate, which in turn drives the rotating column 11 to rotate. Force transmission blocks 12 are fixedly connected to both the left and right sides of the collapse tower 2 to transmit vibrational force to the collapse tower 2. A strip box 13 is fixedly connected to the outside of the force transmission block 12. A square plate 14 is slidably connected to the inner wall of the strip box 13. By providing support to the strip box 13, the square plate 14 can slide horizontally left and right. A striking assembly for striking the force transmission block 12 is fixedly connected to the inner wall of the square plate 14. The striking assembly includes a sliding column 15, which is fixedly connected to the outside of the square plate 14. When the sliding column 15 is subjected to force, it drives the square plate 14 to slide.

[0034] A spring 16 is fitted around the outside of the sliding column 15. Rubber rings 17 are fixedly connected to the adjacent sides of both sliding columns 15. Force plates 18 are fixedly connected to the distant sides of both impact components. The distant sides of the two sliding columns 15 are respectively fixedly connected to the adjacent sides of the two force plates 18. After receiving the thrust of the rotating column 11 through the force plates 18, the sliding columns 15 are pushed to slide together. The adjacent sides of the two rubber rings 17 are in contact with the distant sides of the two force transmission blocks 12, and the force transmission blocks 12 are impacted and vibrated through the rubber rings 17. The adjacent sides of the two force plates 18 are respectively in contact with the outside of the two rotating columns 11. A cylinder 19, the drive source, is fixedly connected to the inner wall of the support leg 3. The drive end of cylinder 19 is fixedly connected to a connecting frame 20. The two connecting frames 20 are fixedly connected to the top of the left and right sides of the collapse tower 2 respectively. The thrust of the drive end of cylinder 19 is transmitted to the connecting frame 20 through the connecting frame 20 to slide, so that the collapse tower 2 slides upward.

[0035] Reference Figure 1 and Figure 4Support plates 21 are fixedly connected to both the front and rear sides of the collapse tower 2. Fixing blocks 22 are rotatably connected to both ends of the support plates 21, providing support to the fixing blocks 22 by fixing the support plates 21. An opening plate 23 is fixedly connected to the far side of every two fixing blocks 22. The opening plate 23 can move in an arc around the fixing block 22 as its center due to the constraint of the fixing blocks 22. Support assemblies for supporting the opening plates 23 are fixedly connected to the far sides of the two support plates 21. Each support assembly includes two connecting blocks 25. The near side of every two connecting blocks 25 is fixedly connected to the far side of the two support plates 21, providing stable support to the connecting blocks 25. A rotating plate 26 is rotatably connected to the near end of every two connecting blocks 25. The rotating plate 26 can rotate around the connecting block 25 as its center due to the constraint of the connecting blocks 25. Multiple strip openings 24 are provided on the adjacent side of the two opening plates 23. The bottom end of the rotating plate 26 engages with the inside of the strip opening 24. Through the strip opening 24, the rotating plate 26 can engage with it and provide support to the opening plate 23.

[0036] Working Principle: The tested concrete is introduced into the collapse tower 2. The drive motor 4 drives the rotating shaft 5 to rotate, which in turn drives the driving wheel 7. The force of the driving wheel 7 is transmitted to the driven wheel 9 via the belt 8. The driven wheel 9 then drives the driven shaft 6 to rotate. The rotating shaft 5 and driven shaft 6 rotate synchronously, causing the circular plate 10 to rotate, which in turn drives the rotating column 11 to rotate. As the rotating column 11 rotates, it intermittently presses against the force plate 18 and pushes it to slide. The sliding of the force plate 18 then causes the sliding column 15 to slide, which in turn... The sliding rubber ring 17 slides, and the sliding column 15 also drives the square plate 14 to slide and compress the spring 16, allowing the spring 16 to store elastic potential energy. This causes the rotating column 11 to no longer press against the force plate 18, and the spring 16 to return to its original position, pushing the square plate 14 to slide. This, in turn, causes the sliding column 15 to return to its original position and pushes the rubber ring 17 to strike the force transmission block 12. The force transmission block 12 transmits the vibration force to the collapse tower 2, allowing the concrete inside the collapse tower 2 to be evenly distributed inside, thereby reducing the physical exertion required for manual operation and improving work efficiency. After assembly inside the collapse tower 2, the two cylinders 19 are driven to push the connecting frame 20 to slide. The two connecting frames 20 then drive the collapse tower 2 to slide upward, allowing the concrete inside the collapse tower 2 to collapse outward under gravity. The collapse degree is then detected by comparing the height of the concrete inside the collapse tower with the height of the collapse tower 2.

[0037] Furthermore, by holding the opening plate 23 and driving the two fixed blocks 22 to rotate around the top of the support plate 21, after the opening plate 23 rotates to a height above the horizontal line, the corresponding rotating plate 26 is then held and rotated around the connecting block 25. The other end of the rotating plate 26 that has not rotated is rotated to engage with the strip opening 24 that is opened at the bottom of the opening plate 23 at this angle. This allows the opening plate 23 to maintain a certain height to adapt to concrete of different heights, thereby improving the flexibility of the device.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
