Description

Technical Field

[0001] The invention relates to the technical field of concrete detection, in particular to a device for detecting the working performance of high-performance concrete. Background Art

[0002] Concrete is an artificial stone material made from cementitious materials (such as cement), aggregates (sand, stone, etc.), water, and, if necessary, admixtures and additives, all mixed in specific proportions, then uniformly mixed, compacted, formed, and cured to harden. Testing the workability of high-performance concrete is crucial because it is often used in large, critical engineering structures, and its performance directly impacts construction efficiency and quality. Poor workability, such as insufficient fluidity, makes it difficult for the concrete to flow evenly within the formwork and fill every corner, leading to defects such as honeycombing, rough surfaces, and voids, which reduce the strength and durability of the structure. Poor cohesion can lead to segregation of the concrete, resulting in uneven performance across different parts and affecting the overall performance of the structure. Poor water retention can cause rapid water loss, hindering the cement hydration reaction, reducing concrete strength, and potentially causing surface cracks. Furthermore, good workability ensures smoother concrete pumping and pouring processes, reducing construction difficulty and time costs, improving efficiency, and ensuring that projects proceed as planned. Therefore, testing the workability of high-performance concrete is crucial for ensuring project quality, improving construction efficiency, and reducing costs.

[0003] In the construction industry, concrete testing is a critical step in ensuring project quality. Slump tests, Vebe consistency tests, and spread tests are common and important testing methods. However, these tests face numerous inconveniences and challenges in practice. Conducting these tests often requires the use of multiple different types of laboratory instruments, such as trowels for smoothing the concrete surface, tamping rods for compacting, and rulers for measuring relevant dimensions. This multitude of instruments not only requires frequent switching and adjustment during operation, which can easily lead to confusion and errors, but also creates significant inconvenience and difficulty in handling and organizing the numerous and diverse instruments. The slump test, in particular, is typically conducted on the ground, but construction sites often have complex and uneven surfaces. This uneven surface can cause uneven forces on the concrete within the slump cone, affecting its flow and sinking behavior. This can lead to biased test results, severely impacting the accuracy of the results and preventing the data from truly reflecting the concrete's actual performance. Furthermore, in slump tests, extracting the slump cone is subject to strict time constraints and must be completed quickly and smoothly within the allotted time. However, due to the intense testing process, any operator error, such as misalignment when extracting the slump cone, can disrupt the concrete's natural flow, causing irregular deformation and ultimately failure of the test. Once a test fails, the tester must re-prepare materials and equipment and repeat the test, significantly increasing the difficulty and time cost of the test and reducing work efficiency.

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figure 1-5 As shown, an embodiment of the present invention provides a device for detecting the working performance of high-performance concrete, including a support mechanism 1, a measuring mechanism 2, and a storage mechanism 3. The support mechanism 1 includes a support base plate 101, two horizontal bubble sensors 102 are fixedly provided on the lower end surface of the support base plate 101, and three electric telescopic rods 104 are hingedly provided on the lower end surface of the support base plate 101 at equal intervals through a ball head seat 105. The lower ends of the three electric telescopic rods 104 are fixedly provided with support legs 103. An extension plate 108 is fixedly provided at the center of the rear side of the support base plate 101, and a limiting rod 107 is threadedly connected at the center of the upper end surface of the extension plate 108.

[0024] The measuring mechanism 2 includes a measuring rod 202, with a hammer head 201 and a sliding cylinder 203 fixed at both ends of the measuring rod 202. A threaded hole 205 is formed at the center of the sliding cylinder 203 away from the measuring rod 202, and a fixed head 204 is threadedly sleeved inside the threaded hole 205.

[0025] The storage mechanism 3 includes a slump cone 303 . A limiting block 304 is fixedly provided on the rear side of the lower end of the slump cone 303 . A limiting hole 305 is provided at the center of the upper end surface of the limiting block 304 .

[0026] The two horizontal bubble sensors 102 are arranged perpendicular to each other. A single-chip microcomputer and a battery 106 are fixedly installed at the center of the lower end surface of the support base plate 101. The single-chip microcomputer is electrically connected to the battery, the horizontal bubble sensor 102 and the electric telescopic rod 104 respectively. A switch is provided on the outside of the single-chip microcomputer, and a charging port is provided on the outside of the battery. A flat surface is provided at the lower end of the measuring rod 202, and the sliding cylinder 203 is movably mounted inside the limiting rod 107. The limiting rod 107 is movably mounted inside the limiting hole 305, and handles 302 are fixedly mounted on both sides of the slump cone 303 near the upper end. A feeding hopper 301 is movably mounted on the upper end of the slump cone 303. Scale lines are provided on the outer surfaces of the measuring rod 202 and the limiting rod 107. The slump cone 303 is located on the upper end surface of the support base plate 101.

[0027] Specifically, this device integrates multiple functions, including slump testing, compaction, and measurement, into a single device, eliminating the need for frequent switching between different instruments in traditional tests. For example, the measuring rod 202 in the measuring mechanism 2 not only measures the lateral width of concrete but also smoothes the concrete surface via the flat surface at its lower end, while the tamping hammer head 201 simultaneously compacts the concrete, reducing operational complexity for the tester. The sliding cylinder 203 and the limiting rod 107 are quickly secured and adjusted via threaded holes 205 and fixed heads 204, providing simple and stable operation and avoiding test failures caused by operational errors in traditional tests.

[0028] The bubble level sensors 102 and electric telescopic rods 104 in the support mechanism 1 work together to automatically detect and adjust the levelness of the support base 101. The extension and retraction of the three electric telescopic rods 104 ensure that the support base 101 remains level even under complex ground conditions, preventing test data deviations caused by uneven surfaces. The bubble level sensors 102 are positioned perpendicular to each other, accurately detecting the horizontality of the support base 101. Adjustments to the electric telescopic rods 104 are controlled by a single-chip microcomputer and battery 106, ensuring test accuracy.

[0029] The limiting rod 107 cooperates with the limiting block 304 through the limiting hole 305 to ensure that the slump cone 303 does not deflect during extraction, maintaining the natural flow of concrete and avoiding test failures caused by deflection of the slump cone 303. The vertical design of the limiting rod 107 allows the slump cone 303 to be extracted quickly and smoothly, meeting the time requirements of the slump test and improving test efficiency.

[0030] The supporting mechanism 1, the measuring mechanism 2 and the storage mechanism 3 adopt a modular design with a compact structure, which is easy to carry and store. For example, the slump cone 303 can be easily moved by the handle 302, and the feeding hopper 301 can be movably mounted on the slump cone 303 for easy use and storage. The overall design of the device takes into account the actual conditions of the construction site, reduces the difficulty of carrying and sorting for test personnel, and improves work efficiency. The outer surfaces of the measuring rod 202 and the limiting rod 107 are both provided with scale lines, which facilitate the test personnel to quickly read the measurement data, thereby improving the accuracy and convenience of the measurement. The limiting rod 107 is used to measure the height of the concrete, and the measuring rod 202 is used to measure the lateral width of the concrete, ensuring the comprehensiveness of the test data.

[0031] Specifically, the single chip microcomputer in this technology controls the operation through the following steps to achieve leveling, ensuring that the support base plate 101 remains level under complex ground conditions, thereby improving the accuracy of the test:

[0032] Two mutually perpendicular horizontal bubble sensors 102 are fixedly mounted at the lower end of the support base 101 to detect the tilt of the support base 101 relative to the horizontal plane. The horizontal bubble sensors 102 can detect the tilt angle of the support base 101 in the X-axis and Y-axis directions in real time and send the detected data to the single-chip microcontroller.

[0033] After receiving the tilt angle data sent by the horizontal bubble sensor 102, the single chip microcomputer processes the data to determine whether the support base 101 is in a horizontal state. If the support base 101 is detected to be tilted, the single chip microcomputer calculates the required adjustment range according to the direction and angle of the tilt.

[0034] The lower end of the support base 101 is hinged with three electric telescopic rods 104 via a ball head seat 105. A support leg 103 is fixed to the lower end of each electric telescopic rod 104. The microcontroller controls the telescopic length of each of the three electric telescopic rods 104 based on the calculated adjustment range to achieve leveling of the support base 101. The microcontroller sequentially controls the telescopic extension and retraction of the three electric telescopic rods 104. For example, if the support base 101 tilts to one side, the microcontroller controls the telescopic rod 104 on that side to shorten while simultaneously extending the telescopic rod 104 on the opposite side, gradually adjusting the support base 101 to a horizontal state. During the adjustment process, the horizontal bubble sensor 102 continuously monitors the horizontal state of the support base 101 and feeds real-time data back to the microcontroller. Based on this feedback data, the microcontroller continuously adjusts the telescopic length of the electric telescopic rods 104 until the support base 101 reaches a horizontal state. When the horizontal bubble sensor 102 detects that the supporting base plate 101 is in a horizontal state, the single chip microcomputer stops adjusting and locks the position of the electric telescopic rod 104 to ensure that the supporting base plate 101 remains stable during the test.

[0035] The microcontroller has an external switch. The operator simply presses the switch, and the microcontroller automatically completes the entire leveling process, eliminating the need for manual intervention and ensuring ease of operation and efficiency. A horizontal bubble sensor 102 monitors the tilt of the support plate 101 in real time. Based on this data, the microcontroller controls the extension and retraction of the three electric telescopic rods 104, gradually adjusting the support plate 101 to a horizontal position. This automated and easy-to-use leveling process ensures both accuracy and stability in the test.

[0036] Working Principle: When in use, the scale lines on the surface of the measuring rod 202 of the measuring mechanism 2 are used to measure the horizontal width, and the limiting rod 107 is used to measure the height. At the same time, the flat surface at the lower end of the measuring rod 202 can be used to level the concrete, and the tamping hammer head 201 is used to tamping the concrete. When the sliding cylinder 203 is sleeved on the limiting rod 107 and adjusted to the appropriate position, it can be clamped and fixed by rotating the fixing head 204;

[0037] Since the limiting rod 107 is sleeved inside the limiting hole 305 of the limiting block 304 and the limiting rod 107 is designed to be vertical, it can prevent the slump cone 303 from deflecting when being pulled out upward, and can also quickly pull out the slump cone 303, making the operation more convenient.

[0038] Before use, the support mechanism 1 can be placed on the ground, and the electric telescopic rod 104 and the horizontal bubble sensor 102 can be turned on to detect the levelness through the horizontal bubble. Then, the three electric telescopic rods 104 can be extended and retracted in sequence to achieve a certain degree of leveling, so as to keep the support base plate 101 horizontal and stable. When the slump cone 303 is tested on the support base plate 101, the accuracy of the experimental data will not be affected by the uneven ground.

[0039] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
