Description

Technical Field

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

[0002] Concrete testing is a crucial step in ensuring the quality of concrete products. Its main purpose is to comprehensively evaluate whether the hardness, quality, strength, and density of concrete meet design requirements through scientific and reasonable testing techniques. Concrete testing devices can make testing more convenient and efficient. Currently, concrete hardness testing typically involves fixing the material first and then using a detector. For example, patent CN220708924U discloses a concrete hardness testing device, including a C-shaped mounting base. A testing platform is fixedly connected to the upper end of the C-shaped mounting base, and a pair of simulation components are located on the upper end of the testing platform. A hardness testing head is connected to the upper internal part of the C-shaped mounting base. The above technical solution uses the simulation components to position the material and then uses the testing head for testing. However, the above simulation components are suitable for blocky or low-height materials. When the material is cylindrical, it is difficult to hold it securely and the operation is more complicated.

[0018] The following examples further illustrate the essential features and advantages of this utility model, but this utility model is not limited to the listed embodiments.

[0019] like Figures 1 to 4As shown, this embodiment of a concrete testing device includes a telescopic assembly 1 and a detector 2 connected to the telescopic assembly 1. A support platform 3 is provided below the detector 2, and a cylindrical concrete sample 10 is placed on the support platform 3. The telescopic assembly 1 drives the detector 2 downward, so that the detector 2 comes into contact with the concrete sample 10 for testing. In this embodiment, the detector is a hardness tester used to detect the hardness of the concrete sample 10. The telescopic assembly 1 includes a driver 11, a moving part 12, and a limiting assembly 4. The driver 11 is connected to the moving part 12 and drives the moving part 12 to move up and down. The driver 11 can be a cylinder. The detector 2 is mounted on the moving part 12 and moves with the moving part 12, thereby moving closer to or away from the concrete sample 10. The limiting component 4 is detachably connected to the moving part 12. The limiting component 4 and the detector 2 are spaced apart along the axial direction of the moving part 12. The limiting component 4 includes a first positioning plate 41, a second positioning plate 42, and a mounting part 43. The mounting part 43 is inserted into the moving part 12. One end of the first and second positioning plates is connected to the mounting part 43, and the other end is a free end. The first positioning plate 41 and the second positioning plate 42 are arranged opposite to each other and form a clamping space 44. The width H of the clamping space 44 gradually increases from top to bottom. The width of the bottom of the clamping space 44 is greater than the diameter of the material 10, and the width of the top of the clamping space 44 is less than the diameter of the product. In this embodiment, the first and second positioning plates are V-shaped. In the above technical solution, the material 10 is placed on the support platform 3. The driver 11 is started, and the telescopic rod of the driver 11 drives the moving part 12 downward, so that the first and second positioning plates press the material 10 from both sides to position it and prevent it from rolling. The detector 2 contacts the material 10 for detection. The above technical solution enables the positioning and detection of cylindrical parts, preventing rolling during the detection process and improving detection stability. Those skilled in the art will understand that a part-limiting structure such as an arc-shaped groove can also be provided on the support platform 3, thereby making the part more stable through upper and lower part-limiting.

[0020] In this embodiment, there are at least two detectors 2, and several detectors 2 are arranged at intervals. By using multiple detectors to detect simultaneously, the detection accuracy and range can be improved. There are at least two sets of limiting components 4, and several limiting components 4 are arranged between the detectors 2. The limiting components 4 are arranged along the axial direction of the material 10, thereby positioning at different positions and further improving stability.

[0021] In this embodiment, the movable part 12 is provided with a mounting groove 121, and the mounting part 43 is inserted into the mounting groove 121, thereby facilitating the installation of the movable part 12. The mounting part 43 is cylindrical for easy insertion. An elastic component 5 is provided between the mounting part 43 and the mounting groove 121. The elastic component 5 engages the mounting part 43 with the mounting groove 121, thereby enabling the mounting part 43 and the mounting groove 121 to engage or disengage. The elastic component 5 includes a spring 51 and a locking head 52. The spring 51 is disposed in the side groove 431 of the mounting part 43. One end of the locking head 52 presses against the spring 51, and the other end is inserted into the locking groove 122 of the movable part 12. The end of the locking head 52 is arc-shaped. The spring force of the spring 51 pushes the locking head 52 into the locking groove 122. The arc-shaped end of the locking head can apply force to the mounting part to make the locking head 52 disengage from the locking groove 122, facilitating disengagement. The support platform 3 has brackets 6 on both sides, and the area between the brackets 6 is a detection area, so that the material 10 can be roughly positioned when placed. The first positioning plate 41 and the second positioning plate 42 are positioning plates with the same structure. The inner side of the positioning plate is provided with an anti-slip part 45, thereby further improving the anti-slip effect. The anti-slip part can be made of rubber material or an anti-slip structure can be opened on the positioning plate.

[0022] The concrete testing device of this embodiment can perform positioning testing on columnar materials, avoiding rolling during the testing process and improving testing stability.

[0023] It should be noted that the above preferred embodiments are merely illustrative of the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
