[0056] A preferred embodiment is given below, and the present invention is described more clearly and completely in conjunction with the accompanying drawings.

[0057] The present embodiment provides an anti-skid test device 100, which can be used to simulate the sliding conditions in a real environment to detect the anti-skid performance of road materials. More preferably, the anti-skid test device 100 can be used to simulate the sliding conditions in a real environment to detect the anti-skid performance of ultra-thin cover materials. Ultra-thin cover is a strong ultra-thin cover that is widely used in various fields. Accurately testing the anti-skid performance of ultra-thin cover on the test device to simulate the anti-skid ability in a real environment is of great significance for selecting appropriate materials or construction.

[0058] like Figure 1 and Figure 2As shown, the anti-slip test device 100 includes a frame 30, and a loading mechanism 40 with adjustable loading force installed on the frame 30, a sliding platform 9, a sample table 13 and a horizontal driving mechanism (not shown in the figure); an ultra-thin cover material is placed on the sample table 13, and the loading mechanism 40 is arranged above the sliding platform 9. The loading mechanism 40 is used to output the loading force, and move downward to act on the sliding platform 9, or move upward to cancel the loading force acting on the sliding platform 9. At least one force sensor 6 is provided on the loading mechanism 40 or the sliding platform 9 to detect the loading force acting on the sliding platform 9 by the loading mechanism 40; a plurality of sliding members 15 and at least one displacement sensor 11 are installed at intervals on the lower surface of the sliding platform 9, the sliding member 15 is used to press the material to be tested, and the displacement sensor 11 is used to detect the sliding displacement of the material to be tested; the sliding platform 9 is configured to be able to adjust the height along the height direction A of the frame 30 according to the height of the material to be tested; the horizontal driving mechanism drives the sliding platform 9 to slide relative to the material to be tested.

[0059] Specifically, in this embodiment, the frame 30 is a metal frame 30, and a loading mechanism 40 is installed on the top of the frame 30. From top to bottom, the loading mechanism 40 includes a loading controller 20, a loading shaft 5 and a loading surface 7. The loading controller 20 can output and adjust the loading force, which is transmitted to the loading surface 7 through the loading shaft 5, and drives the loading surface 7 to move up and down. The loading surface 7 is arranged above the sliding platform 9. When the loading surface 7 moves downward and contacts the sliding platform 9, the loading force can be applied to the sliding platform 9; when the loading surface 7 moves upward and leaves the sliding platform 9, the loading force applied to the sliding platform 9 is cancelled. A sample table 13 is arranged below the sliding platform 9, and the sliding platform 9 presses the material to be tested on the sample table 13 through a sliding member 15. The frame 30 and the sample table 13 are installed on a base 12, and the base 12 stands on the ground through a plurality of legs 17. In other embodiments, according to the different structures of the test device, the loading mechanism 40 can also adopt other different structures and loading methods.

[0060] In this embodiment, the force sensor 6 is arranged on the loading mechanism 40, specifically, on the loading shaft 5, and the force sensor 6 can detect the magnitude of the loading force applied by the loading mechanism 40 on the sliding platform 9. In other embodiments, according to the different types and structures of the components of the anti-slip test device 100, and for the convenience and effective detection of the loading force, the force sensor 6 or other force detection devices can also be arranged on the sliding platform 9, for example, the force sensor 6 detects the magnitude of the loading force according to the deformation of the loading surface 7 pressing the sliding platform 9. The number of force sensors 6 can also be adjusted accordingly as needed.

[0061] The sliding member 15 is specifically a pulley 14. A plurality of pulleys 14 and a displacement sensor 11 are installed at intervals on the lower surface of the sliding platform 9. The loading force borne by the sliding platform 9 presses the pulley 14 tightly against the surface of the material to be tested (ultra-thin cover surface). The displacement sensor 11 installed on the lower surface of the sliding platform 9 and the force sensor 6 installed on the loading mechanism 40 constitute the measurement system of the anti-slip test device 100, and detect the sliding displacement value and the loading force value respectively.

[0062] The horizontal driving mechanism of this embodiment drives the sliding platform 9 to achieve the sliding of the sliding platform 9 relative to the ultra-thin cover surface. During the anti-slip test, the sample table 13 on which the ultra-thin cover surface is laid and placed moves relative to the sliding platform 9. Therefore, in other embodiments, the horizontal driving mechanism can also drive the sample table 13 to achieve the sliding of the ultra-thin cover surface relative to the sliding platform 9.

[0063] The anti-skid test device 100 outputs a loading force through the loading mechanism 40, applies it to the sliding platform 9, and presses it on the material to be tested through the sliding member 15, that is, the material to be tested is pressed on the sample table 13 with a constant pressure to simulate the load conditions in actual use. The loading force is detected by the force sensor 6 to obtain the loading force value; the sliding platform 9 or the sample table 13 is driven to slide by the horizontal driving mechanism, so that the material to be tested produces a relative sliding displacement, and the sliding displacement of the material to be tested is monitored by the displacement sensor 11 to obtain the sliding displacement value. According to the real-time monitoring to obtain the loading force value and the sliding displacement value, the anti-skid performance of the material to be tested can be comprehensively evaluated. The anti-skid test device 100 adjusts the magnitude of the loading force through the loading mechanism 40, which improves the controllability and accuracy of the loading force on the one hand, and on the other hand, can adapt to the anti-skid test needs of materials of different thicknesses corresponding to different loading force magnitudes, and can test not only thick materials but also thin materials, thereby improving the adaptability of the anti-skid test device 100. By adjusting the height of the sliding platform 9, materials of different thicknesses can be loaded, further improving the adaptability of the test materials, especially meeting the test requirements of thin materials, and being able to accurately simulate the anti-slip conditions of thin materials in real environments, thereby improving the accuracy and reliability of the test.

[0064] Among them, the pulley 14 is arranged along the sliding direction B of the sliding platform 9, and several pulleys 14 are arranged in two rows along the sliding direction B, each row has 4 pulleys 14, and the two rows of pulleys 14 are arranged at intervals and distributed around the ultra-thin covering material. In such a structure, the pulley 14 is arranged in the same direction as the sliding direction B of the sliding platform 9, so that the sliding direction of the ultra-thin covering material is consistent with the direction of the sliding friction force, and the sliding friction force effectively and accurately reflects the anti-skid performance of the ultra-thin covering material. Several pulleys 14 are arranged in at least two rows along the sliding direction B, and several sliding members 15 are distributed around the sample to be tested, so that the surface of the ultra-thin covering is evenly stressed, thereby improving the accuracy of the anti-skid test. In other embodiments, the number, number of rows, and distribution of the pulleys 14 can be adjusted as needed.

[0065] Among them, Figure 2 As shown, two positioning members 16 are provided on the sample stage 13. The positioning members 16 are specifically a protective structure protruding from the surface of the sample stage 13. The ultra-thin cover is clamped between the two positioning members 16 to protect the ultra-thin cover to be tested or to avoid interference from foreign objects. The positioning member 16 is configured to be able to adjust the height along the height direction A to meet the protection requirements of materials of different thicknesses and prevent the ultra-thin cover or other types of materials to be tested from falling off.

[0066] like Figure 1 and Figure 2 As shown, the frame 30 is provided with guide rails 8 arranged in the horizontal direction at both ends of the sliding platform 9, and the sliding platform 9 is slidably connected to the guide rails 8 to form a predetermined path for the sliding platform 9 to slide laterally (i.e., horizontally), and a sliding connection method is adopted to drive the sliding platform 9 to slide, with small resistance, reducing interference with the anti-slip test, which is beneficial to improving the accuracy of the anti-slip performance test.

[0067] The frame 30 is provided with a plurality of guide rails 8 which are arranged in parallel and spaced apart from each other, and a slot 10 which is arranged in the horizontal direction is provided on the sliding platform 9. The guide rails 8 are slidably connected to the slot 10, and the sliding platform 9 is arranged so that the slot 10 is selectively detachably connected to one of the plurality of guide rails 8. Guide rails 8 of different height levels are formed by the guide rails 8 which are arranged in parallel and spaced apart from each other, and then the slot 10 of the sliding platform 9 is selectively slidably connected to the guide rail 8, so that the sliding platform 9 can be adjusted to be connected to the target guide rail 8 of a suitable height according to the different thicknesses of the material to be tested, thereby achieving height adjustment. Such a height adjustment method is easy to operate, has a stable and reliable structure, and can achieve stable sliding on each guide rail 8 of an adjustable height, which is beneficial to the accuracy of the test data when comparing the anti-slip performance of materials of different thicknesses.

[0068] like Figure 1As shown, the length of the loading shaft 5 of this embodiment is retractable, and the two ends of the loading shaft 5 are connected to the loading controller 20 and the loading surface 7 respectively. The loading controller 20 is used to control the output of the loading force and drive the loading shaft 5 to retract along the height direction to drive the loading surface 7 to approach, press on or move away from the sliding platform 9; a force sensor 6 is provided on the loading shaft 5, and the force sensor 6 is used to detect the magnitude of the loading force transmitted by the loading shaft 5 according to the expansion and contraction change of the loading shaft 5. The loading mechanism 40 realizes the transmission of the loading force through the retractable loading shaft 5, and adjusts the magnitude of the loading force according to the extended length thereof, so that the expansion and contraction amount can be increased or decreased according to the needs of the anti-slip test or according to the hardness of the material surface, so as to ensure that the material to be tested is firmly pressed on the sample table 13. The force sensor 6 can more accurately identify the magnitude of the effective loading force according to the expansion and contraction change of the loading shaft 5.

[0069] like Figure 1 As shown, the anti-slip test device 100 also includes a controller 20, which is electrically connected to the loading mechanism 40 (specifically, the loading controller 20) and the horizontal driving mechanism, and can control the coordinated actions of each mechanism, including the size of the loading force, the order of the loading force along the height direction A and the driving force along the horizontal direction (i.e., the sliding direction B of the sliding platform), the speed of loading and sliding, and other parameters to ensure the accuracy and repeatability of the test.

[0070] The controller 20 is provided with a switch 1, a safety stop device 2 and a control display screen 3. The control body of the controller 20 is electrically connected to the switch 1, the safety stop device 2 and the control display screen 3. The switch 1, the safety stop device 2 and the control display screen 3 are all electrically connected to the loading controller 20 and the horizontal driving mechanism. The safety stop device 2 can prevent unsafe situations from happening in time, making the test safe and reliable. The control display screen 3 can display the test parameters in real time, so that the user can make adjustments in time.
