Description

Technical Field

[0001] This utility model relates to the technical field of ceramic tile performance testing equipment, and in particular to a ceramic tile anti-slip performance testing device. Background Technology

[0002] In the course of social development, high-quality smooth flooring materials are rapidly gaining traction in building materials consumption, and the manufacturing process of ceramic tiles is constantly innovating. With advantages such as economy, practicality, aesthetics, and ease of cleaning, ceramic tiles have gradually become the mainstream flooring material. However, as a smooth flooring material, while ceramic tiles beautify life and enhance quality of life, the safety accidents and hazards they bring are also increasingly apparent. Slips and falls are considered one of the main causes of accidents in workplaces, public places, and homes. Although slips and falls are related to various external factors, the widespread use of smooth ceramic tiles is undoubtedly one of the significant contributing factors.

[0003] The static slider method, the moving slider method, and the inclined platform method are three main test methods for detecting the anti-slip performance of ceramic tiles, but these three test methods each have the following drawbacks:

[0004] 1. Static slider method: The static slider method mainly measures the maximum static friction force of an object in a static state. However, actual slip accidents mostly occur under dynamic friction conditions (such as walking or running). The dynamic friction coefficient may differ significantly from the static value, resulting in the test results not being completely matched with the actual anti-slip requirements.

[0005] II. Moving slider method: The moving slider method measures the dynamic friction coefficient by sliding at a constant speed. However, when a person walks or runs, there are changes in acceleration, foot pressure distribution, and step frequency. The fixed sliding speed and pressure in the test may not accurately reflect the real slip risk.

[0006] III. Inclined Platform Method: Test personnel walk back and forth on an inclined surface with a certain slope, using the test specimen as a guide. The angle of the slope is gradually increased until a limit angle is reached that allows for safe walking on the slope. This limit is used as the critical angle to reflect the slip resistance of the specimen surface. Because this test method simulates actual usage scenarios, the results are relatively consistent with reality. GB / T 37798-2019 "Evaluation of Slip Resistance Grade of Ceramic Tiles" and GB / T26542-2011 "Test Method for Slip Resistance of Ceramic Tiles" provide detailed specifications for the inclined platform method. However, in actual testing, this method is quite sensitive to the weight of the test personnel. When there is a significant difference in weight between test personnel, even with standard calibration, the results are not ideal. Differences in the test personnel's weight, height, center of gravity, and walking speed all have a significant impact on the results. Furthermore, the detergent solution sprayed on the surface of the ceramic tile sample during the test increases the risk of falls for the test personnel. Although current equipment incorporates safety handrails and ropes, the protective effects are not significant.

[0007] This invention mainly addresses the problems of low accuracy in testing the anti-slip performance of ceramic tiles, significant influence from subjective human factors, and the risk of slipping and falling. Utility Model Content

[0008] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a ceramic tile anti-slip performance testing device to improve the testing accuracy and consistency, eliminate human subjective interference, and enhance the safety factor.

[0009] The technical solution adopted by this utility model to solve its technical problem is as follows: a ceramic tile anti-slip performance testing device, comprising a ceramic tile sample stage, the ceramic tile sample stage including a work surface for placing ceramic tile samples and a support frame for supporting the work surface; the work surface is equipped with a recycling water tank, a counterweight test shoe for simulating the tester's foot stepping on the ceramic tile sample, an infrared locator for collecting instantaneous displacement changes when the counterweight test shoe slides, a force sensor for collecting instantaneous force changes when the counterweight test shoe slides, and an electronic angle meter for collecting angle changes during the test; the support frame is equipped with a control panel, a water supply tank, and a drive mechanism for controlling the work surface to tilt at a standard rate; the recycling water tank and the water supply tank are connected by a water pipe, and the recycling water tank, the water supply tank, and the water pipe together form a circulating liquid supply system; the water supply tank is equipped with a water pump to provide test liquid at a standard flow rate.

[0010] More specifically, in the above technical solution, the support frame is also equipped with a cabinet.

[0011] More specifically, in the above technical solution, the weight test shoe includes a weight test shoe body, a weight rack and several weights, the weight rack is installed and fixed on the weight test shoe body, and the several weights can be added or removed and fitted on the weight rack.

[0012] More specifically, in the above technical solution, the control panel (7) is provided with buttons for controlling the opening and closing of the detection device. The buttons include an automatic button for starting all equipment components with one key and a manual button for manual control of each component individually. The manual buttons include buttons for individually controlling the opening and closing of the circulating liquid supply system, buttons for individually controlling the opening and closing of the infrared positioner, buttons for individually controlling the opening and closing of the force sensor, buttons for individually controlling the opening and closing of the electronic angler, and buttons for individually controlling the opening and closing of the drive mechanism.

[0013] More specifically, in the above technical solution, the water pipe includes a first water pipe, a second water pipe, and a third water pipe. One end of the first water pipe is connected to the second water pipe, and the other end of the first water pipe is connected to the water supply tank.

One end of the third water pipe is connected to the recycling water tank, and the other end of the third water pipe is connected to the water supply tank.

[0014] More specifically, in the above technical solution, both the first water pipe and the third water pipe are flexible pipes.

[0015] More specifically, in the above technical solution, the second water pipe is a rigid pipe.

[0016] The beneficial effects of this utility model are as follows: This utility model provides a ceramic tile anti-slip performance testing device. By using a standard counterweight test shoe to simulate the movement of a human foot on a ceramic tile sample, it replaces traditional manual testing. This effectively avoids the subjective influence of different testers' height, weight, and psychology on the test results, and significantly reduces the personal safety risks caused by testers slipping during traditional testing. The circulating liquid supply system, composed of a recycling tank, a supply tank, and water pipes, effectively saves the demand for test liquid in the anti-slip test. The instantaneous data changes when the counterweight test shoe slides are collected by a force sensor and an infrared locator to control the end of the test, greatly improving the accuracy of the test results.

[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] like Figure 1 , Figure 2 and Figure 3As shown, this utility model discloses a ceramic tile anti-slip performance testing device, comprising a ceramic tile sample stage 1. The ceramic tile sample stage 1 includes a work surface 1-1 for placing ceramic tile samples and a support frame 1-2 for supporting the work surface 1-1. The work surface 1-1 is equipped with a recovery water tank 2, a counterweight test shoe 4 for simulating a person's foot stepping on the ceramic tile sample, an infrared locator 3 for collecting instantaneous displacement changes when the counterweight test shoe 4 slides, a force sensor 6 for collecting instantaneous force changes when the counterweight test shoe 4 slides, and an electronic angler 9 for collecting angle changes during the test. The support frame 1-2 is equipped with a control panel 7, a water supply tank 8, and a drive mechanism 11 for controlling the tilt of the work surface 1 at a standard rate. The recovery water tank 2 and the water supply tank 8 are connected by a water pipe 5, and the recovery water tank 2, the water supply tank 8, and the water pipe 5 together form a circulating liquid supply system. The water supply tank 8 is equipped with a water pump to provide test liquid at a standard flow rate. The purpose of this application in collecting infrared positioning and force value changes is to be able to immediately identify the change at the moment of slippage, and then the test table immediately stops tilting and rotating, in order to control the accuracy of the detection end point. After the rotation stops, the anti-slip performance is determined by the angle of the angler. The larger the angle, the better the anti-slip performance. The angle is the tilt angle of the worktable 1-1.

[0024] Among them, cabinet 10 is also installed on support frame 1-2.

[0025] The infrared locator 3, force sensor 6, electronic angle sensor 9, cabinet 10, and drive mechanism 11 were all purchased directly from the market.

[0026] The counterweight testing shoe 4 includes a shoe body 4-1, a weight holder 4-2, and several weights 4-3. The weight holder 4-2 is fixedly mounted on the shoe body 4-1, and the weights 4-3 can be added or removed from the weight holder 4-2. The weights 4-3 are purchased directly from the market, and the total weight of the weights 4-3 meets the weight requirements of the standard. The bottom of the weight holder 4-2 is shaped similarly to a human foot.

[0027] The control panel 7 is equipped with buttons for controlling the opening and closing of the detection device. The buttons include an automatic button for starting all equipment components with one key and a manual button for manual control of each component individually. The manual buttons include buttons for individually controlling the opening and closing of the circulating liquid supply system, the infrared positioner 3, the force sensor 6, the electronic angler 9, and the drive mechanism 11.

[0028] Water pipe 5 includes a first water pipe 5-1, a second water pipe 5-2, and a third water pipe 5-3. One end of the first water pipe 5-1 is connected to the second water pipe 5-2, and the other end of the first water pipe 5-1 is connected to the water supply tank 8. The second water outlet pipe 5-2 has several water outlet holes 5-4. One end of the third water pipe 5-3 is connected to the recovery water tank 2, and the other end of the third water pipe 5-3 is connected to the water supply tank 8. The second water outlet pipe 5-2 is located on one side of the workbench 1-1, and the recovery water tank 2 is located on the other side of the workbench 1-1. When the workbench 1-1 is tilted, the second water outlet pipe 5-2 is in a higher position, and the recovery water tank 2 is in a lower position. The water coming out of the several water outlet holes 5-4 flows along the ceramic tile sample into the recovery water tank 2. The first water pipe 5-1 and the third water pipe 5-3 are both flexible pipes. Since both the first water pipe 5-1 and the third water pipe 5-3 are connected to the equipment on the workbench 1-1, and the workbench 1-1 needs to rotate, both the first water pipe 5-1 and the third water pipe 5-3 must be flexible pipes. The second water pipe 5-2 is a rigid pipe. The main purpose of this design is to provide a uniform water flow to the entire workbench 1-1.

[0029] The working principle of this application is as follows:

[0030] This application mainly consists of a ceramic tile sample stage 1, a recovery water tank 2, an infrared locator 3, a counterweight test shoe 4, a water pipe 5, a force sensor 6, a control panel 7, a water supply tank 8, an electronic angle sensor 9, a cabinet 10, and a drive mechanism 11. The recovery water tank 2, the water supply tank 8, and the water outlet pipe 5 together form a circulating liquid supply system. During the test, the water supply tank 8, driven by an internal water pump, provides test liquid at a standard flow rate through the water outlet pipe 5. The test liquid is collected by the recovery water tank 2 and input into the water supply tank 8. The counterweight test shoe 4 is equipped with a standard weight to simulate the tester's foot stepping on the ceramic tile sample. The counterweight test shoe 4 is connected to the force sensor 6, which collects the instantaneous force change when the counterweight test shoe 4 slides. The infrared locator 3 is used to collect the instantaneous displacement change when the counterweight test shoe 4 slides. The force sensor 6 and the infrared locator 3 jointly determine the end point of the test. The electronic angle sensor 9 is used to collect the angle changes during the test. After the test is started by the control panel 7, the outlet pipe 5 begins to supply test liquid at a standard flow rate and returns it to the supply tank 8 via the recovery tank 2. The work surface 1-1 of the ceramic tile sample stage 1 begins to tilt at a standard rate under the drive mechanism 11. When it tilts to a certain angle, the counterweight test shoe 4 under the standard counterweight slides. The force sensor 6 and infrared locator 3 collect the instantaneous force and displacement changes. The control panel 7 then controls the end of the test, and the electronic angle sensor 9 collects the test results. This invention mainly uses the counterweight test shoe 4 with standard counterweight to simulate the movement of a human foot on a ceramic tile sample, reducing the risk of slipping and the subjective influence of different testers on the test results. The force sensor 6 and infrared locator 3 jointly determine the end point of the test, and electronic control enables automatic control and automatic data acquisition of the test process, thereby reducing errors in the detection results and improving the accuracy of the test.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
