Description

Technical Field

[0001] This application relates to the field of concrete technology, specifically to a concrete penetration resistance detection device. Background Technology

[0002] The concrete penetration resistance testing device is an instrument for determining the setting time of concrete. It is suitable for measuring the setting time of concrete mixtures with various cements, admixtures, and different concrete mix proportions. The concrete penetration resistance testing device simulates the mechanical response of concrete under external force during the setting and hardening process. It measures the change of penetration resistance over time by vertically pressing a penetration needle into the concrete sample.

[0003] For example, the patent with publication number CN220525585U discloses a concrete penetration resistance meter. This patent uses a pull-on locking column to rotate the support rod to a suitable position and push the locking column to engage in the positioning hole. Through the structure of the locking block and the base, the stability of the mortar sample bucket is increased, making it easier to install and store and increasing the stability of the device.

[0004] In actual testing, there may be situations where multiple samples need to be tested. Due to differences in concrete material mix proportions, mixing processes, curing conditions, etc., the setting time or strength development of different samples may be uneven. Therefore, it is necessary to retest the original test points to verify the consistency of the performance of the new sample with the previous sample and avoid the distortion of test results due to material fluctuations. However, when operators change samples, visual judgment bias or lack of operational skills may cause the penetration needle to fail to accurately align with the original test point, which may result in abnormal values ​​and affect the accurate judgment of concrete setting time or strength.

[0005] Therefore, it is necessary to provide a concrete penetration resistance detection device to solve the above problems.

[0006] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

Detailed Implementation

[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0035] like Figures 1-2 As shown, this application provides a concrete penetration resistance detection device, including a base 1 and a penetration mechanism 2 disposed on the upper end of the base 1. The penetration mechanism 2 is used to detect the penetration resistance of concrete.

[0036] The penetration mechanism 2 includes multiple sets of guide posts 20 fixedly installed on the upper end of the base 1. A crossbeam 27 is fixedly installed on the upper end of the guide post 20. A moving block 22 is slidably installed on the guide post 20. A screw 21 is rotatably installed on the crossbeam 27. The screw 21 is connected to the moving block 22 in a transmission connection. Thus, rotating the screw 21 can drive the moving block 22 to move up and down along the guide post 20.

[0037] Meanwhile, a handwheel 26 is fixedly installed at one end of the screw 21 so that the operator can drive the screw 21 to rotate on the crossbeam 27 through the handwheel 26, thereby driving the moving block 22 to move along the guide post 20;

[0038] A connecting rod 23 is fixedly installed on the moving block 22. A measuring instrument 24 is fixedly installed at one end of the connecting rod 23 so that readings can be obtained in a timely manner. In order to carry out the penetration test smoothly, a penetration needle 25 is detachably installed at the lower end of the measuring instrument 24. The penetration needle 25 is used to penetrate into the concrete to complete the penetration test.

[0039] like Figure 1 and Figures 3-4 As shown, in order to prevent positional deviations when manually changing samples, a switching mechanism 3 is provided on the upper end of the base 1. The switching mechanism 3 is used to switch samples in a timely manner. The switching mechanism 3 includes a first motor 30 fixedly installed at the lower end of the base 1. The output end of the first motor 30 passes through the upper end of the base 1 and is fixedly installed with a mounting plate 31. Thus, starting the first motor 30 can drive the mounting plate 31 to rotate on the upper end of the base 1.

[0040] Meanwhile, in order to prevent the sample from shifting during the switching process, a clamping assembly 32 is provided on the mounting plate 31. The clamping assembly 32 includes a second motor 324 fixedly installed at the middle position of the upper end of the mounting plate 31, and a gear 320 is fixedly installed at the output end of the second motor 324, so that starting the second motor 324 can drive the gear 320 to rotate.

[0041] Furthermore, slide rails 322 are fixedly installed on both sides of the mounting plate 31, and sliders 323 are slidably installed on the slide rails 322. At the same time, racks 321 are fixedly installed on one side of the two sets of sliders 323. The racks 321 mesh with gears 320, so that the second motor 324 can drive the racks 321 through the gears 320 to drive the sliders 323 to move relative to each other along the slide rails 322, thereby causing the sliders 323 on both sides to move closer and further away.

[0042] Meanwhile, clamping blocks 325 are fixedly installed on both sides of the slider 323, and a sample tube 326 is clamped between the clamping blocks 325. When the second motor 324 drives the gear 320 to drive the slider 323 to move closer to each other along the slide rail 322 through the rack 321, the clamping blocks 325 on the slider 323 can clamp and fix the sample tube 326. After the test is completed, it is only necessary to start the second motor 324 to drive the gear 320 in the opposite direction, which will push the slider 323 to move the clamping blocks 325 away from each other along the slide rail 322 through the rack 321, thus unlocking the sample tube 326.

[0043] It should be noted that the sample tube 326 is located directly below the penetration needle 25. When penetration testing is required, the operator can place the two sets of sample tubes 326 between the two sets of clamping blocks 325, and then start the second motor 324 to drive the gear 320 to move the two sets of clamping blocks 325 closer together to fix the sample tube 326. Then, the handwheel 26 can be driven through the screw 21 to make the moving block 22 move the penetration needle 25 into the sample tube 326, thereby conducting a penetration test on the concrete inside.

[0044] Once the first set of tests is completed, simply start the first motor 30 to drive the mounting plate 31 to move the other set of sample cylinders 326 to the lower end of the penetration needle 25 to perform the next set of tests.

[0045] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
