Abstract
Description
Technical Field
[0001] This utility model relates to the field of flooring material testing technology, and in particular to a device for testing the performance of flooring construction materials. Background Technology
[0002] Flooring materials are key materials used to cover and lay building floors to improve the wear resistance, compressive strength and smoothness of the building floors. Before use, the materials usually need to undergo performance testing to ensure that the material performance is qualified.
[0003] However, in existing technologies, when testing the compressive strength of flooring materials, a 40mm x 40mm cubic sample is typically taken after curing and placed on a pressure testing device. The device applies pressure at a uniform rate until the sample breaks. During the pressure test, the cubic sample needs to be clamped and fixed to ensure that it does not shift during the pressure test. However, existing devices typically use clamping plates on both sides of the cubic sample that can be brought together, meaning the clamping force can only be applied to one side of the cubic sample. This causes the cubic sample to easily shift under pressure, resulting in deviations in the test data and affecting the smooth progress of the test. A solution is proposed to address the problems mentioned in the background technology. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a performance testing device for flooring construction materials. The aim is to improve the current method for testing the compressive strength of flooring materials. Typically, a 40mm x 40mm cubic sample is taken after curing and placed on a pressure testing device. The device applies pressure at a uniform rate until the sample breaks. During the pressure test, the cube needs to be clamped and fixed to ensure it does not shift during the pressure test. However, existing devices usually use clamping plates on both sides of the cube that can converge, meaning the clamping force can only be applied to one side of the cube. This causes the cube to easily shift under pressure, leading to deviations in the test data and affecting the smooth progress of the testing.

[0029] 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.
[0030] Reference Figures 1 to 4 As shown, one embodiment of this utility model includes a testing platform 1. Clamping rods 2 are slidably connected to both sides of the upper end of the testing platform 1. Clamping plates 3 are fixedly connected to one end of each clamping rod 2. Roller sets 20 are rotatably connected to both sides of the clamping rods 2. A fixing frame 12 is fixedly connected to the upper end of the testing platform 1. A hydraulic cylinder 13 is fixedly connected to the upper end of the fixing frame 12. A pressure head 14 is fixedly connected to the output end of the hydraulic cylinder 13. Support legs 9 are fixedly connected to all four sides of the lower end of the testing platform 1. The lower end of the test platform 1 is provided with a clamping mechanism, which includes an electric push rod 16. One side of the electric push rod 16 is fixedly connected to the lower end of the test platform 1. The lower ends of the two clamping rods 2 are fixedly connected with toothed rods 18. One end of each toothed rod 18 is fixedly connected with a reinforcing rib 21. The lower end of the test platform 1 is rotatably connected with a first gear 17. The outer surface of the first gear 17 meshes with one side of each of the two toothed rods 18. The output end of the electric push rod 16 is fixedly connected to one side of one of the toothed rods 18.
[0031] In this embodiment, when testing the performance of the flooring material, a 40mm×40mm material cube can be placed on the testing platform 1. Then, by activating the electric push rod 16, one of the toothed rods 18 can be moved, which in turn drives the first gear 17 meshing with it to rotate. At the same time, the other toothed rod 18 meshing on the other side will also move, thereby driving the clamping rod 2 fixedly connected to it to move. The moving clamping rod 2 can drive the clamping plate 3 to converge, and the clamping plate 3 clamps the material to be tested. At the same time, the clamping plate 3 adopts a V-shaped structure design. This method allows the clamping plate 3 to clamp the material to be tested simultaneously on all four sides of the material to be tested when the device is fixing the material to be tested. This makes the clamping force on the material to be tested more uniform, improves the stability of the material after clamping, and makes the device more stable when performing testing.
[0032] Example 2, as Figures 1 to 3 As shown, protective covers 10 are provided on both sides of the upper end of the testing platform 1. Connectors 8 are fixedly connected to both sides of the two protective covers 10. Visible tempered glass 11 is fixedly connected to one side of the two protective covers 10. A bidirectional lead screw 7 is rotatably connected to one side of the testing platform 1. One end of two connectors 8 is threadedly connected to the outer surface of the bidirectional lead screw 7. A second gear 4 is fixedly connected to the middle of the bidirectional lead screw 7. A mounting bracket 15 is fixedly connected to one side of the lower end of the testing platform 1. A third gear 5 is rotatably connected to one side of the mounting bracket 15. The outer surface of the second gear 4 meshes with the outer surface of the third gear 5. A motor 6 is fixedly connected to one side of the mounting bracket 15. The output end of the motor 6 is fixedly connected to one side of the third gear 5. A slide rod 19 is fixedly connected to the other side of the testing platform 1. The outer surface of the slide rod 19 is slidably connected to one end of two other connectors 8.
[0033] In this embodiment, during the testing process, the starting motor 6 can drive the third gear 5 to rotate, which in turn drives the second gear 4 meshing with it to rotate. At this time, the second gear 4 can drive the bidirectional lead screw 7 to rotate, which in turn drives the threaded connecting piece 8 to move. The moving connecting piece 8 can drive the protective cover 10 fixedly connected to it to move. By merging the two protective covers 10, the area around the testing device is protected. This reduces the influence of surrounding factors on the testing data and also prevents the material from splashing when it is crushed under excessive pressure, thus preventing the flying debris from hitting the testing personnel.
[0034] Working Principle: When using the device, a 40mm x 40mm material cube is placed on the testing table 1 and clamped. After closing the protective cover 10, the hydraulic cylinder 13 is activated to push the pressure head 14 to pressurize the material. While clamping the material, the electric push rod 16 moves one of the toothed rods 18, which in turn rotates the meshing gear 17. Simultaneously, the other toothed rod 18 on the other side moves, thus moving the clamping rod 2 fixedly connected to it. The moving clamping rod 2 causes the clamping plate 3 to converge, clamping the material. The clamping plate 3 employs a V-shaped structure design, ensuring that the clamping plate remains firmly in place when the device is fixing the material. 3. The V-shaped clamping plate 3 can simultaneously clamp all four sides of the material to be tested, making the clamping force on the material more uniform and improving the stability of the material after clamping. This makes the device more stable during testing. When the protective cover 10 is closed, the starting motor 6 can drive the third gear 5 to rotate, which in turn drives the second gear 4 to rotate. At this time, the second gear 4 can drive the bidirectional lead screw 7 to rotate, which in turn drives the threaded connecting piece 8 to move. The moving connecting piece 8 can drive the protective cover 10 fixedly connected to it to move. By merging the two protective covers 10, the area around the testing device is protected. This reduces the influence of surrounding factors on the test data and also prevents the material from splashing when it breaks under overpressure, thus preventing the flying debris from hitting the testing personnel.
