Description

Technical Field

[0001] This utility model relates to the field of civil engineering testing and inspection instruments and equipment, and in particular to a testing device based on the concrete strength test in civil engineering. Background Technology

[0002] Concrete strength testing equipment is used to accurately determine the compressive and tensile mechanical properties of concrete, verifying whether they meet design standards and specifications. This provides data support for project quality control and experimental basis for concrete mix optimization and process improvement. It helps prevent structural collapses due to insufficient strength, ensuring the safety of buildings throughout their lifespan. Real-time monitoring allows for timely adjustments to construction processes, reducing rework costs and improving construction efficiency.

[0003] The concrete strength testing device applies axial pressure to the concrete specimen using a press. Sensors collect pressure values ​​and specimen deformation data in real time. When the specimen fails, the peak pressure corresponds to the compressive strength, and the strength value is calculated in combination with the specimen size. The rebound hammer uses a spring rod to impact the concrete surface and calculates the strength by the correlation between rebound energy and surface hardness.

[0004] In existing technologies, some concrete strength testing devices simply place the concrete on a workbench. However, when manually placing the test block, it is not aligned with the center of the workbench, causing the test block to deviate from directly below the hydraulic rod, resulting in an offset of the load application point and uneven stress distribution on the surface of the test block. Therefore, a testing device based on civil engineering concrete strength testing is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a testing device based on the concrete strength test in civil engineering. It aims to improve the problem in the prior art where the test block is not aligned with the center of the workbench when it is manually placed, which causes the test block to deviate from the center of the hydraulic rod and the load application point to shift, resulting in uneven stress distribution on the surface of the test block.

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

[0007] A testing device for concrete strength testing in civil engineering includes a workbench. A rotating column is fixedly connected to the inner wall of the workbench. Two transmission rods are rotatably connected to the outer wall of the rotating column. Rotating rods are rotatably connected to both ends of the two transmission rods. Clamping blocks are rotatably connected to the top of the multiple rotating rods. A slide rail is fixedly connected to the inner wall of the workbench. A cylinder is fixedly connected to the inner wall of the workbench. A side cover is detachably connected to the rear side of the workbench. A disassembly assembly for disassembly is installed on the inner wall of the workbench.

[0008] As a further description of the above technical solution:

[0009] The disassembly assembly includes a housing, the outer wall of which is detachably connected to the inner wall of the workbench, a control rod slidably connected to the inner wall of the housing, and a wedge block fixedly connected to the other end of the control rod. The outer wall of the housing is detachably connected to the inner wall of the side cover.

[0010] As a further description of the above technical solution:

[0011] An elastic spring is fixedly connected to the outer wall of the wedge block, and the other end of the elastic spring is fixedly connected to the inner wall of the outer shell.

[0012] As a further description of the above technical solution:

[0013] The inner wall of the workbench is fixedly connected with multiple telescopic springs, and the other end of each telescopic spring is fixedly connected with a connecting rod.

[0014] As a further description of the above technical solution:

[0015] The bottom of the connecting rod is fixedly connected to a plurality of limiting blocks, and the outer walls of the plurality of limiting blocks are in contact with the outer wall of the wedge block;

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

[0017] The inner wall of the workbench is fixedly connected to a slide rail, the bottom of the transmission rod is slidably connected to the inner wall of the slide rail, the inner wall of the slide rail is provided with a groove, and the inner wall of the transmission rod is slidably connected to the inner wall of the groove.

[0018] As a further description of the above technical solution:

[0019] The other end of the cylinder is fixedly connected to the bottom of the transmission rod, and the outer wall of the worktable is provided with multiple sliding grooves, and the bottom of the rotating rod is slidably connected to the inner wall of the sliding groove.

[0020] As a further description of the above technical solution:

[0021] A top plate is fixedly connected to the top of the workbench, and a hydraulic rod is fixedly connected to the bottom of the top plate. A control panel is installed on the outer wall of the workbench, and multiple control buttons are provided on the inner wall of the workbench.

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

[0023] 1. In this utility model, the cylinder is started, and the start of the cylinder drives the bottom of the transmission rod to slide inside the sliding groove opened on the inner wall of the slide rail, thereby realizing the rotation of the transmission rod. The rotation of the transmission rod drives the top of the rotating rod to slide on the inner wall of the sliding groove. At this time, the rotating rod will slide according to the trajectory of the sliding groove, thereby moving the clamping block towards the center, thereby fixing the concrete and preventing the concrete from shifting during testing. This would cause the load applied by the hydraulic rod and hydraulic cylinder to be unevenly transmitted to the surface of the test block, causing the test block to be prematurely damaged by local pressure, thus affecting the evaluation of concrete quality.

[0024] 2. In this utility model, pressing the control lever causes the wedge block to move, and the movement of the wedge block causes the limiting block to move towards the outer wall of the outer shell. The movement of the limiting block, controlled by the telescopic spring, causes the connecting rod to move towards the inner wall of the worktable, thereby causing the limiting block to disengage from the inner wall of the outer shell. At this time, the side cover is not fixed inside the worktable, thus completing the disassembly of the side cover from the rear side of the worktable, so as to control the wedge block to squeeze the limiting block out and complete the disassembly.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a testing device for concrete strength testing in civil engineering, comprising a workbench 1, which serves as a basic support structure to support various components. A rotating column 5 is fixedly connected to the inner wall of the workbench 1, providing a rotational support point for a transmission rod 6. Two transmission rods 6 are rotatably connected to the outer wall of the rotating column 5, and the two transmission rods 6 are symmetrically arranged to achieve balanced transmission. Rotating rods 7 are rotatably connected to both ends of the two transmission rods 6, and the transmission rods 6 and rotating rods 7 are rotatably connected to achieve motion transmission. Clamping blocks 8 are rotatably connected to the top of the multiple rotating rods 7, and the rotating rods 7 drive the clamping blocks 8 to move to clamp the concrete. A slide rail 4 is fixedly connected to the inner wall of the workbench 1, providing a sliding track for the bottom of the transmission rods 6.

[0034] A cylinder 3 is fixedly connected to the inner wall of the workbench 1. The cylinder 3 serves as a power source to drive the transmission rod 6 to move. A side cover 9 is detachably connected to the rear side of the workbench 1. The side cover 9 is used to close the rear side of the workbench 1 and facilitate maintenance. A disassembly assembly for disassembly is installed on the inner wall of the workbench 1. The disassembly assembly enables the quick disassembly of the side cover 9. A slide rail 4 is fixedly connected to the inner wall of the workbench 1. Again, the fixed setting of the slide rail 4 is emphasized. The bottom of the transmission rod 6 is slidably connected to the inner wall of the slide rail 4. The bottom of the transmission rod 6 slides along the inner wall of the slide rail 4 to achieve displacement before rotation. A groove 2 is opened on the inner wall of the slide rail 4. The groove 2 provides a rotation guide path for the bottom of the transmission rod 6. The inner wall of the transmission rod 6 is slidably connected to the inner wall of the groove 2. The bottom of the transmission rod 6 slides in the groove 2 and rotates around the rotating column 5.

[0035] The other end of the cylinder 3 is fixedly connected to the bottom of the transmission rod 6. The cylinder 3 and the bottom of the transmission rod 6 are fixedly connected to directly transmit power. The outer wall of the workbench 1 is provided with multiple sliding grooves 18. The sliding grooves 18 provide a moving track for the top of the rotating rod 7. The bottom of the rotating rod 7 is slidably connected to the inner wall of the sliding groove 18. The bottom of the rotating rod 7 moves along the inner wall of the sliding groove 18 to realize the displacement of the top clamping block 8. The top of the workbench 1 is fixedly connected to the top plate 17. The top plate 17 provides installation support for the hydraulic rod 21. The bottom of the top plate 17 is fixedly connected to the hydraulic rod 21. The hydraulic rod 21 is used to apply the test load to the concrete. The outer wall of the workbench 1 is equipped with a control panel 19. The control panel 19 is used to centrally control the operation of each component. The inner wall of the workbench 1 is provided with multiple control buttons 20. The control buttons 20 are the input components for specific control commands.

[0036] Reference Figure 1 , Figure 4 and Figure 5 The disassembly assembly includes a housing 15, which serves as the main structure of the disassembly assembly. The outer wall of the housing 15 is detachably connected to the inner wall of the workbench 1. The detachable connection between the housing 15 and the inner wall of the workbench 1 facilitates installation and maintenance. A control rod 16 is slidably connected to the inner wall of the housing 15. The control rod 16 can slide on the inner wall of the housing 15 to achieve displacement transmission. A wedge block 13 is fixedly connected to the other end of the control rod 16. The control rod 16 and the wedge block 13 are fixedly connected and move synchronously. The outer wall of the housing 15 is detachably connected to the inner wall of the side cover 9. The detachable connection between the housing 15 and the inner wall of the side cover 9 allows the side cover 9 to be combined with the disassembly assembly.

[0037] An elastic spring 12 is fixedly connected to the outer wall of the wedge block 13. The elastic spring 12 provides the wedge block 13 with a reset elastic force. The other end of the elastic spring 12 is fixedly connected to the inner wall of the outer shell 15. The two ends of the elastic spring 12 are respectively connected to the wedge block 13 and the outer shell 15 to realize the reset function. Multiple telescopic springs 10 are fixedly connected to the inner wall of the worktable 1. The telescopic springs 10 provide elastic support and movement control for the limit block 11. The other end of the telescopic spring 10 is fixedly connected to the connecting rod 14. The telescopic spring 10 and the connecting rod 14 are connected to transmit elastic force. Multiple limit blocks 11 are fixedly connected to the bottom of the connecting rod 14. The connecting rod 14 drives the limit blocks 11 to move to realize the limit fixation of the side cover 9. The outer walls of the multiple limit blocks 11 are in contact with the outer wall of the wedge block 13. The limit blocks 11 and the wedge block 13 realize displacement transmission and locking through the contact of the outer walls.

[0038] Working principle: When concrete load testing is required, the concrete is placed on the top of the workbench 1. At this time, the cylinder 3 is activated. The activation of the cylinder 3 drives the bottom of the transmission rod 6 to slide inside the groove 2 opened in the inner wall of the slide rail 4, thereby realizing the rotation of the transmission rod 6. The rotation of the transmission rod 6 drives the top of the rotating rod 7 to slide on the inner wall of the sliding groove 18. At this time, the rotating rod 7 will slide according to the trajectory of the sliding groove 18, thereby moving the clamping block 8 towards the center, thus fixing the concrete and preventing the concrete from shifting during testing. This would cause the load applied by the hydraulic cylinder to be unevenly transmitted to the surface of the test block, causing the test block to be prematurely damaged by local pressure, thus affecting the concrete quality assessment.

[0039] When the workbench 1 needs to be inspected, the control lever 16 is pressed. The pressing of the control lever 16 causes the wedge block 13 to move. The movement of the wedge block 13 causes the limiting block 11 to move towards the outer wall of the outer shell 15. Through the control of the telescopic spring 10, the movement of the limiting block 11 causes the connecting rod 14 to move towards the inner wall of the workbench 1, thereby causing the limiting block 11 to disengage from the inner wall of the outer shell 15. At this time, the side cover 9 is not fixed inside the workbench 1, thus completing the disassembly of the side cover 9 from the rear side of the workbench 1, which facilitates the inspection of the inner wall of the workbench 1. The elastic spring 12 is used to control the sliding of the wedge block 13 on the inner wall of the outer shell 15, so as to control the wedge block 13 to squeeze the limiting block 11 out, thereby completing the disassembly.

[0040] 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.
