Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of concrete processing, and more specifically, relates to a device for detecting the slump of concrete. Background Art
[0002] The technical field of concrete processing covers the entire process of concrete production, construction, and maintenance. The production stage includes raw material preparation, batching, mixing, and transportation. The key lies in ensuring the accuracy of the concrete formula and the stability of raw material quality. Therefore, during the process of processing and batching concrete, it is necessary to frequently detect the slump of concrete. That is, by measuring the fluidity of concrete in a free state, its plasticity and fluidity during the construction process are determined to ensure that the concrete can be evenly distributed and filled in the formwork to form a structure. The detection process usually uses a slump cone. The concrete sample is loaded into the conical container, and after being vibrated in a specific manner, the conical container is removed. The slump is judged according to the flow degree of the concrete and expressed in numerical value. This value reflects the fluidity and plasticity of the concrete and directly affects the construction efficiency and quality. Slump detection is an important part of concrete mix design and quality control and is crucial for ensuring the quality of engineering buildings and the stability of structures.
[0003] In the prior art, the common process for detecting the slump of concrete is to pour the concrete into the slump cone multiple times. After each pouring, it is necessary to use a hammer-shaped object such as a stick or a tamper to hammer the concrete in the slump cone to flatten the concrete accumulation layer, and then continue to pour the concrete until the concrete exceeds the plane at the top of the slump cone. Finally, use a hammer-shaped object to flatten the concrete accumulation layer until it is flush with the top of the slump cone. The plane flush with the top of the slump cone is defined as the initial plane. Then, the slump cone is removed from bottom to top along the center line of the concrete in the direction of gravity. Finally, observe the height difference between the plane after the concrete slides down in a free state and the initial plane to evaluate the fluidity of the concrete in a free state.
[0004] In the above process, since it is easy to spill the concrete near or on the surface of the slump cone during the transfer of the concrete to the slump cone at the construction site, and it is easy for the construction workers to be interfered during the process of manually removing the slump cone. Also, the phenomenon of the inner wall of the slump cone hitting the concrete is likely to occur during the whole process, which is likely to affect the final evaluation result and increase the evaluation error. At the same time, it is difficult to find a hammering component that matches the mouth of the slump cone at the construction site, which affects the detection progress. Summary of the Utility Model

[0036] Embodiment
[0037] In the prior art, during the process of transferring concrete to the slump cone at the construction site, the concrete is often easily spilled near or on the surface of the slump cone. When the construction workers manually remove the slump cone, they are easily interfered, and during the whole process, the phenomenon of the inner wall of the slump cone hitting the concrete is likely to occur, which is likely to affect the final evaluation result and increase the evaluation error. At the same time, it is difficult to find a hammering component that matches the cone opening of the slump cone at the construction site, which affects the progress of the detection.
[0038] Based on this, in order to solve the above technical problems that concrete is likely to spill near or on the surface of the slump cone, and during the process of removing the slump cone, it is prone to interference, increasing the evaluation error and affecting the progress of detection, this embodiment provides a concrete slump detection device. For details, please refer to Figures 1-6 , including: a slump cone 1, a support frame 2, and a support rod 3. Among them, the slump cone 1 and the support frame 2 are fixed on a base, and the base can be a flat fixing plate 6. The slump cone 1 is a conical structure with both ends penetrating. Its caliber in the direction of concrete pouring is small, and the side opposite to the small caliber is the large caliber. A handle 12 is fixed at each end of the slump cone 1. The support frame 2 is arranged adjacent to the slump cone 1. A support rod 3 is rotatably connected to the top of the support frame 2 through a bearing, and the support rod 3 is perpendicular to the support frame 2. A through-flow guide cover 4 is fixed at one end of the support rod 3, and a hammering assembly 5 is fixed at the other end of the support rod 3. The hammering assembly 5 can extend into the slump cone 1 and hammer the concrete inside the slump cone 1.
[0039] In some embodiments, refer to Figure 1 , the hammering assembly 5 includes: a fixed pulley group 51, a pulling rope 52, and a counterweight 53. Among them, the fixed pulley group 51 includes a fixed pulley and a pulley seat, and the pulley seat is fixed on the support rod 3. The pulling rope 52 is arranged on the fixed pulley and can move along the rotating direction of the fixed pulley. The counterweight 53 is fixedly connected to one end of the pulling rope 52. The construction worker stretches the pulling rope 52 forcefully to lift the counterweight 53, and when the construction worker releases the pulling rope 52, the counterweight 53 hammers the concrete under the action of gravity, so as to finally flatten the conical surface at the top of the concrete.
[0040] In some embodiments, refer to [[ID=eleven]] Figures 2-3 , the support frame 2 includes a fixing part 21 and a lifting part 22. The plane presented by one end of the fixing part 21 is the same plane as the plane where the slump cone 1 is located; the lifting part 22 is placed inside the fixing part 21 and can be lifted or lowered along the axial direction of the fixing part 21. The construction worker controls the height of the lifting part 22 relative to the fixing part 21 to adapt to slump cones 1 of different heights and models, increasing the adaptability of this device. Among them, a number of limit holes 211 are provided on the fixing part 21, a limit groove 221 is provided inside the lifting part 22, a compression spring 222 is fixedly installed in the limit groove 221, a pressure ball 223 is fixed along the telescopic direction of the compression spring 222, and the pressure ball 223 can be placed on the limit hole 211 to limit the height of the lifting part 22. When it is necessary to adjust the height of the lifting part 22 relative to the fixing part 21, the construction worker presses the pressure ball 223 forcefully to make the pressure ball 223 disengage from the limit hole 211, and then stretches or contracts the lifting part 22 until the specified height, and then the pressure ball 223 extends into the specified limit hole 211. At this time, the pressure ball 223 is re-limited by the limit hole 211.
[0041] In some embodiments, referring to Figure 4 , in order to further reduce the interference of the inner wall of the slump cone 1 on the concrete, the slump cone 1 in this solution can be separated into two halves along the direction perpendicular to the concrete pouring direction. A number of fixing holes 11 are provided on the end surface of any one half, and plugging columns corresponding to the fixing holes 11 are provided on the end surface of the other half. The plugging columns can be inserted into the fixing holes 11 and be limited. In this solution, the existing way of removing the slump cone 1 is changed from the original upward removal direction to the removal direction along both ends perpendicular to the concrete pouring direction, further reducing the interference of the inner wall of the slump cone 1 on the concrete. Specifically, the construction workers can combine or separate the two halves of the slump cone 1 through the handles 12 at both ends.
[0042] In this embodiment, referring to Figure 1 and Figure 5 , the device further includes a support base 8 fixed to the fixing plate 6. A bidirectional lead screw 9 is mounted on the support base 8. Specifically, bearings are sleeved on the support base 8, and both ends of the bidirectional lead screw 9 are respectively sleeved on the bearings. At this time, the bidirectional lead screw 9 can rotate relative to the support base 8. Two sliders 10 are slidably connected to the bidirectional lead screw 9. Any one slider 10 is fixedly connected to one of the handles 12, and one end of the bidirectional lead screw 9 is fixedly connected to a handwheel 13. The bidirectional lead screw 9 is composed of two lead screws welded together relatively to form a complete bidirectional lead screw 9, and the rotation directions of the two lead screws are opposite. Since the threads on the bidirectional lead screw 9 are arranged in the reverse direction, the two sliders 10 can approach or move away from each other relatively. At this time, the construction workers can combine or separate the two halves of the slump cone 1 by rotating the handwheel 13, thereby reducing the complexity of manual operation.
[0043] In some embodiments, referring to Figure 4 , an isolation layer 14 is provided on the inner surface of the slump cone 1 to prevent the concrete from sticking to the inner wall of the slump cone 1. The isolation layer 14 is coated with a release agent to prevent the concrete from sticking to the inner wall of the slump cone 1. The isolation layer 14 can also be made of thin film plastic material.
[0044] In some embodiments, referring to Figure 6 , the slump cone 1 and the support frame 2 are respectively fixed on the trolley 7 to facilitate the movement of the device.
[0045] In this device, the slump cone 1 and the support frame 2 are usually fixed on a base, which can be the fixed plate 6 or a flat ground. Since the support rod 3 can rotate relative to the support frame 2, when it is necessary to pour concrete into the slump cone 1, the flow guide cover 4 can be rotated to the cone opening of the slump cone 1, and then the concrete is poured. Since the flow guide cover 4 is in a horn-shaped structure as a whole, the concrete can be smoothly guided into the slump cone 1 to avoid the concrete being poured onto the outer surface or near the slump cone 1. When there is no concrete interference on the outer surface of the slump cone 1, it can be quickly removed from the concrete, thereby reducing the interference of the inner wall of the slump cone 1 on the concrete and further reducing the evaluation error. When it is necessary to hammer the concrete inside the slump cone 1, the support rod 3 can be rotated to make the hammering assembly 5 connected to the support rod 3 face the cone opening of the slump cone 1, and then the construction worker can hammer the concrete by controlling the hammering assembly 5. For this reason, the construction worker does not need to search for a hammering object that matches the cone opening of the slump cone 1 on site, reducing the impact on the detection progress.
[0046] In the present utility model, unless otherwise clearly specified and defined, the first feature being "on" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. The meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0047] In the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "connection", "fixation", etc. shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection, an electrical connection, or communicable with each other; it may be directly connected, or indirectly connected through an intermediate medium, and may be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
