Description

Technical Field

[0001] This utility model relates to the field of civil engineering testing technology, and in particular to a strength testing fixture for concrete testing. Background Technology

[0002] Concrete is an artificial stone material formed by mixing cement, sand, stone, water, and other materials in a certain proportion, followed by stirring, molding, and curing. It possesses characteristics such as high compressive strength and good durability, making it one of the most fundamental structural materials in construction engineering. Strength testing equipment is used in concrete testing because the strength of concrete directly relates to the safety and stability of the building structure. This equipment can accurately measure the compressive and tensile strength indicators of concrete under stress by applying pressure and tension. Its role is to provide scientific and quantitative basis for concrete quality control, project acceptance, and structural safety assessment, ensuring that the building project meets load-bearing requirements within its design service life.

[0003] The strength testing fixtures used for concrete testing include ultrasonic detectors and rebound hammers. The ultrasonic detector in the concrete strength testing fixture mainly consists of an ultrasonic transmitting transducer, a receiving transducer, a signal amplification and processing circuit, a data acquisition and display component, and a main control unit. The transmitting transducer converts electrical signals into ultrasonic waves and transmits them into the concrete. The receiving transducer receives the ultrasonic signals propagated through the concrete and converts them back into electrical signals. The signal amplification and processing circuit amplifies weak signals and filters out interference. The data acquisition and display component records and visualizes parameters such as the propagation time and amplitude of the ultrasonic waves in real time. The main control unit coordinates the work of each component and controls the testing process according to a preset program, thereby realizing the detection and analysis of internal defects and strength of the concrete.

[0004] In the existing technology, some ultrasonic detectors in strength testing fixtures used for concrete testing require operators to manually apply coupling agent to the probe head. When applying the coating manually, it is impossible to ensure the amount of coupling agent applied to the probe head. Therefore, this strength testing fixture for concrete testing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a strength testing fixture for concrete testing, which aims to improve the problem in the prior art that requires operators to manually take the coupling agent and apply it to the probe head. When applying the coating manually, it is impossible to ensure the amount of coupling agent applied to the probe head.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A strength testing fixture for concrete testing includes an outer shell, a protective shell fixedly connected to the front interior of the outer shell, a movable rod slidably connected to the top of the protective shell, a force-applying ring fixedly connected to the outside of the movable rod, a force-applying plate fixedly connected to the bottom of the movable rod, and an adjustment component for adjusting the size fixedly connected to the front of the protective shell.

[0015] A transmission pipe is fixedly connected to the front side of the protective shell, a one-way valve is fixedly connected to the outside of the transmission pipe, and a display screen is fixedly connected to the front side of the outer shell.

[0016] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the moving rod moves, causing the force ring to move downward, which in turn causes the spring to squeeze. The moving rod drives the force plate at the bottom to move, so that the coupling agent is transmitted under the action of the transmission tube, thereby realizing the pressing and extrusion of the coupling agent. In addition, the amount of coupling agent extruded can be precisely controlled by pressing, avoiding dosage deviations caused by manual application, thereby ensuring that the amount of coupling agent used during testing is uniform and appropriate.

Under the action of the electric push block, the extruded coupling agent is evenly applied, thereby achieving uniform application to probes of different sizes. In addition, it can be adapted to various probe sizes, ensuring that different specifications of detection tools can obtain a consistent application effect, thereby avoiding the problem of uneven application caused by size differences.

[0031] 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.

[0032] Reference Figure 2 and Figure 3 This utility model provides an embodiment of a strength testing fixture for concrete testing, comprising an outer shell 1 that protects the internal structure. A protective shell 2 is fixedly connected to the front of the outer shell 1, protecting the various internal mechanical mechanisms and ensuring stable operation. A movable rod 3 is slidably connected to the top of the protective shell 2, and a force-applying ring 4 is fixedly connected to the outside of the movable rod 3. A force-applying plate 7 is fixedly connected to the bottom of the movable rod 3. The movable rod 3 receives external force and moves accordingly, causing the force-applying ring 4 to move along with it. The force-applying ring 4 applies force to other components. The force-applying plate 7 moves along with the movable rod 3 as it moves, compressing other components. An adjustment assembly for size adjustment is fixedly connected to the front of the protective shell 2.

[0033] Reference Figure 2 and Figure 4The adjustment assembly includes a second protective shell 10, the rear of which is fixedly connected to the front of a first protective shell 2. The second protective shell 10 protects the internal driving components, ensuring their stable operation, and also protects the internal adjustment assembly. Two motors 11 are slidably connected to the front of the second protective shell 10. A rotating rod 12 is fixedly connected to the driving end of each motor 11, and a gear 13 is fixedly connected to the outside of the rotating rod 12. The motors 11 are the driving source for the adjustment assembly, thereby driving the rotating rod 12 to rotate. The rotating rod 12 receives power from the motors 11, thus operating and ensuring stable rotation. The gear 13 receives the rotational force from the rotating rod 12, thus causing it to rotate. A rack 15 is fixedly connected to the inner wall of the second protective shell 10. The top inner wall of the protective shell 10 allows gear 13 to mesh with rack 15, causing rotating rod 12 to move. A moving part 14 is rotatably connected to the outside of rotating rod 12. An adjusting plate 16 is fixedly connected to the bottom of moving part 14. Moving part 14 moves with moving rod 3 during its movement, allowing adjusting plate 16 to be adjusted. Adjusting plate 16 adjusts the application range to accommodate probes of different sizes. An electric pusher block 18 is fixedly connected to the inner wall of protective shell 10. A brush plate 19 is fixedly connected to the drive end of electric pusher block 18. Electric pusher block 18 receives signals from the device and operates to stabilize it. Brush plate 19 moves under the action of electric pusher block 18, allowing brush plate 19 to evenly apply coupling agent.

[0034] Reference Figures 1 to 3The inner wall of the protective shell 2 is fixedly connected to a placement box 9, which is used to place the internal coupling agent and stabilize it. A spring 6 is fixedly connected to the bottom of the force ring 4. The spring 6 receives the pushing force of the force ring 4, thereby squeezing it back to its original position. The outer side of the force plate 7 is slidably connected to the inner wall of the placement box 9. The force plate 7 receives the pushing force of the moving rod 3, thereby squeezing the coupling agent inside the placement box 9. A fixing post 22 is fixedly connected to the top inner wall of the protective shell 2. The outer side of the spring 6 is slidably connected to the fixing post 22. The inner wall of column 22 is fixed, and column 22 protects the internal spring 6 structure, making it stable. A transmission pipe 8 is fixedly connected to the front of the protective shell 1, and a one-way valve 5 is fixedly connected to the outside of the transmission pipe 8. The transmission pipe 8 is used to transmit the coupling agent inside the placement box 9 to the next part. The one-way valve 5 is electrically driven, thereby regulating the flow rate of the coupling agent. A display screen 21 is fixedly connected to the front of the outer shell 1. The display screen 21 is used to display the data after detection. A fixing ring 23 is fixedly connected to the top of the moving rod 3. The fixing ring 23 receives... The operator's pushing force causes the moving rod 3 to move. The bottom of the fixing ring 23 contacts the top of the protective shell 2 as the moving rod 3 moves. The fixing ring 23 also limits the movement of the moving rod 3, stopping its movement. The outside of the gear 13 contacts the outside of the rack 15. The gear 13 receives the rotational force from the rotating rod 12, thus moving under the action of the rack 15. The adjusting plate 16 is slidably connected to the outside of the protective shell. At the bottom of the second protective shell 10, the adjusting plate 16 moves under the action of the moving part 14 to adjust the coating area. The bottom of the protective shell 10 is fixedly connected to the coating shell 20, where the probe is coated. The inner wall of the coating shell 20 is fixedly connected to the coating cloth 17, which receives the coupling agent transmitted by the transmission tube 8 for coating. The rear side of the adjusting plate 16 is slidably connected to the front side of the coating cloth 17, and the rear side of the adjusting plate 16 and the coating cloth 17 are sealed to prevent the coupling agent from flowing to other places.

[0035] Working principle: The operator moves the fixed ring 23, which in turn moves the moving rod 3, causing the bottom force ring 4 to move and the spring 6 to compress. At this time, the moving rod 3 moves the bottom force plate 7, which moves within the placement box 9. This causes the coupling agent in the placement box 9 to move under the action of the transfer box. Under the action of the one-way valve 5, the flow rate is controlled to ensure uniformity. After application, the operator releases the force on the fixed ring 23, and the moving rod 3 returns to its original position under the action of the spring 6. This achieves the pressing and extrusion of the coupling agent. In addition, the amount of coupling agent extruded can be precisely controlled by pressing, avoiding dosage deviations from manual application, thus ensuring that the amount of coupling agent used during testing is uniform and appropriate.

[0036] After the extruded coupling agent enters the coating cloth 17 through the transfer tube 8, the operator starts the motor 11, which drives the rotating rod 12 to rotate. The rotating rod 12 then drives the gear 13 to rotate, which, under the action of the rack 15, moves the moving part 14 on the rotating rod 12. This moves the adjusting plate 16 at the bottom to adjust the opening to fit the current probe head. At this time, the operator starts the electric push block 18, which moves the brush plate 19 to the coating cloth 17. The brush plate 19 makes the coupling agent evenly distributed on the surface of the coating cloth 17, thus achieving uniform coating for probe heads of different sizes. In addition, it can adapt to various probe head sizes, ensuring that different specifications of detection tools can obtain consistent coating effects, thereby avoiding uneven coating problems caused by size differences.

[0037] 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.
