Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, and in particular to a device for testing the performance of ready-mixed concrete. Background Technology

[0002] Ready-mixed concrete, also known as commercial concrete, refers to a concrete mixture made from cement, aggregates, water, and, as needed, admixtures and mineral additives, mixed in a specific ratio at a batching plant, measured and mixed, and then transported to the site of use within a specified time. Precise measurement and strict control of the mix proportions ensure stable and reliable concrete quality. It offers numerous advantages, allowing for the customization of special-performance concrete to meet diverse project needs, such as high-strength, high-performance, and self-compacting concrete. Simultaneously, it reduces dust and noise pollution at construction sites, contributing to environmental protection. Ready-mixed concrete is widely used in various construction projects, including high-rise buildings, bridges, roads, and water conservancy facilities, and is an indispensable material in modern construction, significantly improving construction efficiency and project quality.

[0003] Ready-mixed concrete requires ultrasonic testing because it can assess strength and uniformity in quality control, identify internal defects and detect crack depth in defect detection, determine setting time and assess durability during construction monitoring, and provide objective and accurate data as a basis for quality acceptance in project acceptance, thereby ensuring the structural safety of buildings, smooth construction, and compliance with quality requirements.

[0004] However, some existing devices cannot quickly install and disassemble ultrasonic detectors when testing the performance of ready-mixed concrete. They usually require bolts and nuts for installation and disassembly, and special tools are needed to tighten and loosen the bolts and nuts. This can affect the detection accuracy of the ultrasonic detector or cause instability in its installation, which greatly reduces the efficiency of ultrasonic detector installation and disassembly. This, in turn, has an adverse effect on the progress of the entire ready-mixed concrete performance testing work, which not only prolongs the testing cycle but also increases the project cost and time cost. Therefore, in order to address the above shortcomings, a ready-mixed concrete performance testing device is proposed to solve the above problems. Utility Model Content

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, when installing the ultrasonic detector, after the docking plate slides into the fixed frame, pressing the positioning plate causes the connecting ring to drive the fixed ring to compress the spring, allowing the locking plate to slide into the slot through the slide groove. Then, rotating the positioning plate locks it into the positioning slot, thus completing the installation. When disassembly is required, rotating the positioning plate disengages it from the positioning slot, and the spring releases its elasticity, causing the locking plate to disengage from the docking plate, allowing for quick removal of the ultrasonic detector. This eliminates the need for numerous tools, significantly shortening the maintenance and replacement time of the ultrasonic testing instrument and improving the overall efficiency of the testing device. Especially when frequently switching between different models of ultrasonic testing instruments or performing equipment maintenance, it greatly reduces equipment downtime, ensuring the continuity and efficiency of testing work.

[0025] 2. In this utility model, cylinder two drives push rod two to move the sliding plate back and forth, and the rotating rod two inside the sliding plate rotates accordingly, thereby driving the two clamping plates to open and close. This ensures the synchronicity and accuracy of the movement of the two clamping plates, so that the concrete will not be displaced or shaken due to external force or vibration during ultrasonic testing. This ensures the accuracy and reliability of the ultrasonic testing results and provides a strong guarantee for accurately evaluating the performance of ready-mixed concrete. Whether it is detecting internal structural defects in concrete or measuring its strength and other performance parameters, more accurate and reliable data can be obtained.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0034] Reference Figures 1 to 3 This utility model provides an embodiment of a ready-mixed concrete performance testing device, including an outer frame 1. The outer frame 1 serves as the main frame of the entire testing device, providing an installation foundation and working space for other components. A driving mechanism is provided on the top front side of the outer frame 1. An installation plate 4 is fixedly connected to the bottom of the driving mechanism. A quick-release mechanism is provided inside the installation plate 4. A docking plate 14 is slidably connected to the bottom of the quick-release mechanism. An ultrasonic detector 15 is fixedly connected to the bottom of the docking plate 14. A coupling pad 16 is fixedly connected to the bottom of the ultrasonic detector 15. A clamping mechanism is provided on the inner bottom side of the outer frame 1.

[0035] The quick-release mechanism includes a rotating rod 6, which is externally slidably connected to the inside of the mounting plate 4. A positioning plate 7 is fixedly connected to the top of the rotating rod 6. When the rotating rod 6 rotates, the positioning plate 7 slides or engages in the internal positioning groove 11 of the top frame 10, thereby locking or unlocking the entire quick-release mechanism. A spring 8 is sleeved on the outside of the rotating rod 6. One end of the spring 8 is fixedly connected to the bottom of the fixing ring 9, and the other end is fixedly connected to the inside of the mounting plate 4. Under normal conditions, the spring 8 is in a certain pre-compression state, and its elastic force acts between the fixing ring 9 and the mounting plate 4. This force is transmitted to the locking plate 12 through the rotating rod 6, keeping the locking plate 12 in a specific position in the locking groove 18 or the sliding groove 17, thereby achieving the engaging connection between the mating plate 14 and the fixing frame 13.

[0036] Reference Figures 2 to 4 A retaining ring 9 is rotatably connected to the outside of the rotating rod 6. The retaining ring 9 restricts the position of the spring 8 and provides partial support and guidance for the rotating rod 6, ensuring the stability of the rotating rod 6 during rotation and sliding. The external rotatable connection of the rotating rod 6 is inside the retaining ring 9, and a connecting ring 30 is fixedly connected to the outside of the rotating rod 6. When the positioning plate 7 is pressed, causing the connecting ring 30 to be squeezed downward, the retaining ring 9 will move downward with the rotating rod 6, compressing the spring 8. When the spring 8 releases its elastic force, the retaining ring 9 can stably support the spring 8 on the rotating rod 6 to return to its original shape. The top of the mounting plate 4 is fixedly connected to a top frame 10, and a positioning groove 11 is provided inside the top frame 10. The outside of the positioning plate 7 is slidably connected to the inside of the positioning groove 11. The bottom of the rotating rod 6 is fixedly connected to a locking plate 12. The bottom of the mounting plate 4 is fixedly connected to a fixing frame 13. The inside of the docking plate 14 is provided to a sliding groove 17. The outside of the locking plate 12 is slidably connected to the inside of the sliding groove 17. The docking plate 14 is the intermediate component connecting the ultrasonic detector 15 and the mounting plate 4. Its top is engaged with the fixing frame 13 through the locking plate 12, and its bottom is fixedly connected to the ultrasonic detector 15. During installation, the docking plate 14 slides in along the guide structure inside the fixing frame 13, and then is fixed by locking the locking plate 12 into the locking groove 18. During disassembly, after the locking plate 12 is disengaged from the locking groove 18, the docking plate 14 can be easily removed from the fixing frame 13, thereby realizing the quick disassembly of the ultrasonic detector 15. The docking plate 14 has a slot 18 inside, and the external locking plate 12 is rotatably connected to the inside of the slot 18. In the normal installation state, the slot 18 and the sliding groove 17 cooperate to limit the displacement of the docking plate 14 in the horizontal and vertical directions, ensuring the stability of the ultrasonic detector 15 installation. When disassembling, the locking plate 12 is disengaged from the slot 18 under the elastic force of the spring 8 and the external force, allowing the docking plate 14 to be removed from the fixing frame 13.

[0037] Reference Figures 2 to 4The driving mechanism includes cylinder 2, the bottom of which is mounted on the top front side of the outer frame 1. Cylinder 2 is the power source for driving the mounting plate 4 to move up and down. A push rod 3 is fixedly connected to the output end of cylinder 2. When cylinder 2 receives a control signal to start, push rod 3 will extend and retract according to the movement of the piston inside the cylinder. When extended, it can push the mounting plate 4 and the components connected below it to move downward, so that the ultrasonic detector 15 is closer to the concrete to be tested; when retracted, it drives the mounting plate 4 to move upward, so that the ultrasonic detector 15 is away from the concrete, realizing the lifting and lowering action control during the detection process. A guide rod 5 is fixedly connected to the top rear side of the mounting plate 4. The function of the guide rod 5 is to ensure the accuracy and stability of the movement direction of the mounting plate 4 during its up and down movement, so that it can only move vertically along the preset guide channel inside the outer frame 1, avoiding tilting or shaking that would affect the detection accuracy.

[0038] Reference Figures 3 to 5 The clamping mechanism includes a drive assembly, which includes a second cylinder 19. The second cylinder 19 is the power drive component of the clamping mechanism. The rear of the second cylinder 19 is mounted inside the rear of the outer frame 1. A push rod 20 is fixedly connected to the output end of the second cylinder 19. The drive assembly is externally fixedly connected to the bottom inside the outer frame 1. When the second cylinder 19 is activated, the push rod 20 extends and retracts. The extension and retraction of the push rod 20 causes the connected sliding plate 21 to move forward and backward. The sliding plate 21 is fixedly connected to the front of the drive assembly. Two rotating rods 22 are rotatably connected to the left and right sides of the sliding plate 21. When the sliding plate 21 moves forward and backward, the rotating rods 22 rotate around their connection point with the sliding plate 21. By changing the rotation angle, the clamping plate 23 is pushed or pulled to open and close. Two clamping plates 23 are slidably connected to the top of the outer frame 1. When the sliding plate 21 moves back and forth under the action of the push rod 20, the rotating rod 22 will rotate accordingly, thereby driving the clamping plate 23 to perform corresponding opening and closing actions. The bottom of both clamping plates 23 is fixedly connected to a limit frame 24. One of the clamping plates 23 is fixedly connected to a guide plate 25 on its left side. During the clamping process, the limit frame 24 will slide within the limit groove 29 to ensure that the clamping plate 23 can only perform horizontal opening and closing movements, and will not move vertically or in other directions, thereby improving the stability and accuracy of clamping. A guide frame 26 is slidably connected to the outside of the guide plate 25. The left side of the guide frame 26 is fixedly connected to the right side of another clamping plate 23. A guide groove 27 is opened inside the guide frame 26. A guide frame 28 is fixedly connected to the top of the guide plate 25. The outside of the guide frame 28 is slidably connected to the inside of the guide groove 27. A limit groove 29 is opened on the bottom side of the inner side of the outer frame 1. The outside of the limit frame 24 is slidably connected to the inside of the limit groove 29, thereby ensuring the stability and accuracy of the concrete clamping and preventing the concrete from shifting or shaking due to unstable clamping during the testing process, which would affect the accuracy of the ultrasonic testing results.

[0039] Working principle: When using this ready-mixed concrete performance testing device, the concrete to be tested can first be placed on the bottom inside the outer frame 1. Then, cylinder 2 19 can be activated, which drives push rod 20 and sliding plate 21 to move, thereby causing rotating rod 22 to rotate. At this time, the limiting frame 24 will slide inside the limiting groove 29, thereby allowing the two clamping plates 23 to clamp and fix the concrete. Then, cylinder 1 2 can be activated, which causes push rod 3 and mounting plate 4 to move downward, thereby allowing guide rod 5 to slide inside the outer frame 1. At this time, ultrasonic detector 15 and coupling pad 16 will move downward, thereby allowing coupling pad 16 to contact the top of the concrete. At this time, ultrasonic testing of the concrete can be performed by ultrasonic detector 15.

[0040] When the ultrasonic detector 15 needs to be quickly disassembled, the positioning plate 7 can be rotated to disengage it from the positioning groove 11. This will align the locking plate 12 with the sliding groove 17. The spring force of the spring 8 will then disengage the locking plate 12 from the docking plate 14, allowing the docking plate 14 to disengage from the fixed frame 13, thus enabling the rapid disassembly of the ultrasonic detector 15. When the ultrasonic detector 15 needs to be installed, the docking plate 14 can be aligned and slid into the fixed frame 13. Then, the positioning plate 7 can be pressed to slide into the top frame 10, causing the connecting ring 30 to move downward and press the fixed ring 9 downward. This will compress the spring 8, causing the locking plate 12 to slide into the slot 18 through the sliding groove 17. Then, the positioning plate 7 can be rotated to slide into the positioning groove 11, and the locking plate 12 will slide into the slot 18, thus locking the docking plate 14 into the fixed frame 13, enabling the rapid installation of the ultrasonic detector 15.

[0041] 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.
