Description

Technical Field

[0001] This utility model belongs to the field of concrete construction engineering technology, and specifically relates to a concrete sample performance testing device. Background Technology

[0002] The concrete processing involves the use of large quantities of sand, stone, fly ash, cement, and additives. These components are mixed in specific proportions and thoroughly stirred to produce the finished concrete product. After completion, the factory typically prepares samples for performance testing.

[0003] In the prior art, such as the concrete sample performance testing device with application number 202311482905.2, there is a testing platform, a compressive strength testing component for testing the compressive strength of the concrete sample and a flexural strength testing component for testing the flexural strength of the concrete sample. The testing platform is provided with a hydraulic rod and at least two guide support columns. A movable beam is slidably provided on the guide support columns, and the output end of the hydraulic rod is connected to the lower surface of the movable beam.

[0004] In the above, the universal support bracket and universal base are arranged opposite to each other, so that both the compressive strength test component and the flexural strength test component can be installed in the test area, which to some extent reflects a good continuous testing function. However, after reading the technical solution, it is found that the sample clamp in the compressive strength test component cannot accommodate the concrete blocks, which means that the concrete blocks need to be crushed and dispersed during the test, which leads to a decrease in test efficiency and is not conducive to the comprehensive collection of concrete test data.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] This utility model embodiment proposes a concrete sample performance testing device, including a base 1; exemplarily, such as... Figures 1-3 As shown.

[0024] A bonding roller 3 is placed on the top of the base 1. A connecting plate 4 is provided on the side of the bonding roller 3. A sliding seat 5 is rotatably provided on the surface of the connecting plate 4. A straight rail 6 is slidably fitted to the bottom of the sliding seat 5. An electric push rod 7 is adapted to be installed on the side of the sliding seat 5. The bottom of the electric push rod 7 is fixedly installed to the base 1. The bonding roller 3 includes an inner cylinder 31. A screw 32 is installed through the inner cavity of the inner cylinder 31. A retaining ring 33 is sleeved on the outer surface of the screw 32. A hinge rod 34 is rotatably installed on the surface of the retaining ring 33. A support plate seat 35 is adapted to be installed on the end face of the hinge rod 34. A conical cylinder 8 is placed on the side of the bonding roller 3.

[0025] The conical cylinder 8 includes a base cylinder 81 that fits against the surface of the inner cylinder 31. A wave groove 82 is provided on the outer wall of the base cylinder 81. A barrier strip 83 is provided on the side of the wave groove 82. A rotating wheel 36 is sleeved on the end face of the screw 32.

[0026] A boss block 84 is provided on the side of the wave groove 82. The surface of the boss block 84 is provided with an inner groove 85, and the boss blocks 84 are arranged in a ring.

[0027] Specifically, through the cooperation between the base 1 and the bonding roller 3, the concrete can be evenly coated when it adheres to the surface of the conical cylinder 8, avoiding the impact of lumps of concrete on the test results. Furthermore, the cooperation between the connecting plate 4 and the sliding seat 5 ensures that the rotation of the bonding roller 3 remains relatively stable. The sliding cooperation between the electric push rod 7, the sliding seat 5 and the straight rail 6 allows the bonding roller 3 and the conical cylinder 8 to fit more tightly, resulting in higher uniformity of the concrete and better test accuracy. At the same time, the sleeve of the retaining ring 33 and the screw 32 makes the rotation of the screw 32 more uniform and also ensures the rotation and extension of the hinge rod 34. The support plate seat 35 can simultaneously support the inner cylinder 31, avoiding deformation of the inner cylinder 31 caused by concrete impact.

[0028] Furthermore, barrier strips 83 and corrugated grooves 82 are provided on the surface of the base cylinder 81 to physically divide and press the concrete, reducing the impact of concrete blockage. At the same time, additional boss blocks 84 and inner grooves 85 are provided to ensure that the concrete at the edge has a lasting rolling effect, which indirectly enhances the test results. A rotating wheel 36 is provided on the end face of the screw 32, which allows the screw 32 to rotate on its own, facilitating the rotational support of the roller 3.

[0029] The top of the barrier strip 83 is fitted with a wiping roller 9; for example, such as Figures 2-4 As shown.

[0030] The center of the erasing roller 9 is fitted with a four-corner base 10.

[0031] A reinforcing rib plate 13 is installed on the upper surface of the base 1. A pen-shaped cylinder 12 is adapted to be installed on the top of the reinforcing rib plate 13. A stabilizing part 11 is provided on the end face of the pen-shaped cylinder 12. The bottom of the stabilizing part 11 is adapted to be installed on the four corner base 10.

[0032] The conical cylinder 8 is fitted with a test ring 14, and a rangefinder 15 is mounted on the top of the test ring 14. There are several rangefinders 15.

[0033] Specifically, the combination of the barrier strip 83 and the wiping roller 9 allows the concrete to be evenly compacted by the wiping roller 9. Simultaneously, the stable mounting of the four corner bases 10 allows the wiping roller 9 to continuously remove excess concrete. Furthermore, the combination of the reinforcing plate 13, the pen-shaped cylinder 12, and the stabilizing part 11 allows the wiping roller 9 to better achieve the pressing and coating function according to the coating thickness of the concrete, which facilitates the accuracy of the test. In addition, the combination of the rangefinder 15 and the test ring 14 allows the concrete test to be continuous and efficient, which is conducive to the stability of the test.

[0034] The barrier strip 83 is a continuous curved surface; for example, such as... Figures 3-5 As shown.

[0035] The height of the barrier strip 83 is higher than the radius height of the base cylinder 81.

[0036] The base 1 is equipped with a protective cover 2 on its side, and the protective cover 2 is symmetrically distributed.

[0037] Specifically, by setting the height of the barrier strip 83 to be greater than that of the foundation cylinder 81, the concrete can be contained after being pressed, and by setting the protective cover 2, concrete can be prevented from contaminating the test personnel.

[0038] Working principle: First, concrete is pressed into the corrugated groove 82 and the inner groove 85. Then, the rotating wheel 36 is shaken to make the screw 32 rotate evenly. The rotation of the screw 32 will drive the hinge rod 34 to extend outward along the diameter. Then, the support plate seat 35 will provide stable support for the inner cylinder 31. Next, the rotation of the inner cylinder 31 can provide rotational support for the foundation cylinder 81, and compact and squeeze the concrete in the corrugated groove 82 and the inner groove 85. At the same time, the pen-shaped cylinder 12 is opened, and the pen-shaped cylinder 12 pushes the stabilizing part 11 and the four corner platform 10 to move linearly. Finally, the wiping roller 9 compacts and presses the concrete on the surface of the foundation cylinder 81 a second time to reduce the occurrence of lumps.

[0039] After the concrete is pressed, the conical cylinder 8 is removed and installed inside the test ring 14. The rangefinder 15 continuously tests the concrete data to complete the test process.
