The tread panels can be used for passengers to stand and walk, and have the functions of bearing the weight of passengers and realizing personnel transportation. In order to avoid congestion caused by people staying at the entrance of the escalator, passengers need to pass through the tread panels as quickly as possible to ensure the smooth operation of the escalator.

In addition, features defined as "first" or "second" may explicitly or implicitly include one or more of the features, and are used to distinguish and describe features, without distinction of order or importance.

[0035] like Figures 1 to 9 As shown, a laboratory tread anti-slip performance testing device includes a support frame 1, a test platform 2, a driving mechanism 3 and a stepping mechanism 4;

[0036] The test platform 2 is rotatably disposed on the support frame 1, and the test platform 2 is used to place the test sample 10;

[0037] The driving end of the driving mechanism 3 is in transmission connection with the test platform 2, and the driving mechanism 3 is used to drive the test platform 2 to rotate relative to the support frame 1 to change the inclination angle of the test platform 2;

[0038] The test platform 2 is fixedly connected with an angle encoder 21, and the angle encoder 21 is used to test the tilt angle of the test platform 2;

[0039] The stepping mechanism 4 is located above the test platform 2, and the stepping mechanism 4 includes a linear motor 41, a pressure sensor 42 and a test shoe 43. The linear motor 41 is hinged to the support frame 1, one end of the pressure sensor 42 is fixedly connected to the output shaft of the linear motor 41, and the other end of the pressure sensor 42 is hinged to the test shoe 43; the linear motor 41 drives the test shoe 43 to move up and down so that the test shoe 43 steps on the surface of the test sample 10.

[0040] By setting the stepping mechanism 4, the linear motor 41 drives the test shoe 43 to reciprocate up and down. When testing, the driving mechanism 3 drives the test platform 2 to rotate, so that a certain inclination angle is formed between the test platform 2 and the test sample 10 and the horizontal plane, and the linear motor 41 drives the test shoe 43 to move downward, and the sole of the test shoe 43 moves downward in a horizontal state (at this time, the heel of the test shoe 43 is located close to the side of the test sample 10 that is inclined upward, such as Figure 5 As shown in the figure, until the heel of the test shoe 43 first contacts the test sample 10, because the pressure sensor 42 is hinged to the test shoe 43, and there is an inclination angle between the test sample 10 and the horizontal plane, under the continued driving of the linear motor 41, the forefoot of the test shoe 43 gradually steps on the test sample 10 and fits with the test sample 10, so that the test shoe 43 simulates the movement of a human foot stepping on the test sample 10. The friction force F is generated by the contact between the test shoe 43 and the test sample 10. 摩 (upward along the slope), the pressure sensor 42 can test the friction force F between the test shoe 43 and the test sample 10 at different angles. 摩 The support force F of the test shoe 43 with the slope 支 The resultant force F合 , wherein the support force F of the inclined surface on the test shoe 43 支 Vertically upward on the slope, F 合 The force value collected by the pressure sensor 42 is used in the utility model to determine whether the test shoe 43 will slide on the test sample 10 based on the reading of the pressure sensor 42 by the following method:

[0041] First, by presetting a normal pressure F 法 , this F 法 represents the pressure applied by the test shoe 43 to the test sample 10 under normal conditions, such as when the weight of a person is 60 kg. 法 When the gravity is 60kg, when the test shoe 43 steps on the surface of the test sample 10, the linear motor 41 drives the test shoe 43 to pressurize the surface of the test sample 10. The test platform 2 starts the test from 0° (or a preset angle), and gradually increases the inclination angle of the test platform 2. At each inclination angle, the stepping mechanism 4 simulates the stepping motion of a person. When the test shoe 43 contacts the surface of the test sample 10, the pressure sensor 42 starts to read the readings during the stepping motion. The following conditions exist:

[0042] 1. No sliding: When the reading F of the pressure sensor 42 is 合 Can stably reach the preset F 法 (gravity of 60 kg), that is, the linear motor 41 drives the test shoe 43 to pressurize the surface of the test sample 10 to reach F 法 (gravity at 60kg), it indicates that the friction between the test shoe 43 and the test sample 10 is large enough to prevent the test shoe 43 from sliding on the test sample 10. In this case, it is determined that no sliding occurs between the test shoe 43 and the test sample 10;

[0043] 2. Sliding condition: When the reading F of the pressure sensor 42 合 Unable to reach the preset F 法 (gravity at 60kg), or even if it is reached but cannot be maintained stably (i.e. the value cannot be increased or begins to fluctuate), that is, the linear motor 41 drives the test shoe 43 to pressurize the surface of the test sample 10 but cannot reach F 法 (gravity at 60kg), it proves that the friction between the test shoe 43 and the test sample 10 is insufficient to prevent the sliding of the test shoe 43. At this time, it is judged that the test shoe 43 will slide on the surface of the test sample 10, and the tilt angle of the test platform 2 when sliding occurs is recorded. This angle is the critical angle of slipping.

[0044] When evaluating the anti-slip performance, the larger the critical slip angle, the more stable the test shoe 43 can remain without slipping at a larger tilt angle. Therefore, the larger the critical slip angle, the better the anti-slip performance of the test sample 10.

[0045] The laboratory tread anti-skid performance testing device can simulate the movement of a person's foot stepping on a test sample, and judge whether the test shoe 43 will slide on the test sample 10 through the reading of the pressure sensor 42, thereby evaluating the anti-skid performance of the tread of the test sample 10, avoiding test deviations caused by the psychological reactions of the testers, improving the accuracy of the test, and avoiding testers from slipping and getting injured when the surface of the test sample 10 is unbalanced, effectively improving the safety of the test, and solving the technical problems of poor accuracy and poor test safety of existing laboratory anti-skid performance testing devices.

[0046] It should be noted that the tread anti-slip performance testing device used in this laboratory adopts the reading of the pressure sensor 42 to determine whether the test shoe 43 will slide on the test sample 10. There is no need to use the naked eye to judge. The operator only needs to use the reading of the pressure sensor 42 to determine whether the test shoe 43 slides. Even slight sliding can be detected, and the test accuracy is high.

[0047] like Figure 3 As shown, specifically, one end of the pressure sensor 42 away from the linear motor 41 is fixedly connected to a first hinged seat 421, and the first hinged seat 421 is provided with a first rotating shaft 4211. The inner wall of the sole of the test shoe 43 is fixedly connected to a first connecting seat 431, and the first connecting seat 431 is connected to the heel of the test shoe 43. The first connecting seat 431 is provided with a first through hole matching the first rotating shaft 4211. The first rotating shaft 4211 is inserted into the first through hole and hinged to the first connecting seat 431 to realize the articulation of the pressure sensor 42 and the test shoe 43.

[0048] like Figure 4 As shown, it is further explained that a linear module 22 is fixedly provided on the upper surface of the test platform 2 along the left-right direction, and the linear module 22 is provided with a movable table 221 that moves left and right. The upper end surface of the movable table 221 is fixedly connected with a storage platform 23, and the test sample 10 is placed on the storage platform 23. The linear module 22 drives the storage platform 23 to move left and right relative to the test platform 2.

[0049] In order to achieve the anti-slip effect, the surface of the test sample 10 is usually provided with textures during production. The depth and density of the textures at different positions may cause non-uniformity on the surface of the test sample 10 due to production errors. In order to prevent the uneven surface state of the test sample 10 from affecting the test accuracy, the placement platform 23 is provided, and the linear module 22 is provided on the upper surface of the test platform 2. The linear module 22 drives the placement platform 23 to move left and right relative to the test platform 2 to change the stepping position of the test shoe 43 on the surface of the test sample 10, so as to facilitate the anti-slip performance test of different positions of the test sample 10, so as to obtain more comprehensive and more reliable test results.

[0050] like Figure 6 As shown, the storage platform 23 moves to the lower left relative to the test platform 2, so that the test shoe 43 steps on the right side of the test sample 10. Figure 7 As shown, the storage platform 23 moves to the upper right relative to the test platform 2, so that the test shoe 43 steps on the left side of the test sample 10. The tread anti-slip performance testing device is suitable for testing non-uniform test samples.

[0051] Preferably, a guide rail 24 is fixedly provided on the upper surface of the test platform 2 along the left-right direction, the guide rail 24 and the linear module 22 are spaced apart along the width direction of the test platform 2, a slider 241 is slidably provided on the guide rail 24, and the upper end surface of the movable platform 221 and the upper end surface of the slider 241 are fixedly connected to the storage platform 23 respectively.

[0052] By setting the guide rail 24, and the guide rail 24 and the linear module 22 are spaced apart along the width direction of the test platform 2, the guide rail 24 can provide a guiding function for the storage platform 23 during the left and right movement, and provide a supporting function for the storage platform 23, thereby effectively improving the sliding stability of the storage platform 23 during the left and right sliding process.

[0053] Specifically, the horizontal plane where the upper end surface of the slider 241 is located is at the same height as the horizontal plane where the upper end surface of the moving platform 221 is located, so that when the test shoe 43 steps on the surface of the test sample 10, the test sample 10 will not be uneven, thereby ensuring the accuracy of the test.

[0054] like Figure 5 As shown, it is further explained that a placement frame 231 is provided on the upper surface of the placement platform 23 , and the test sample 10 is placed in the placement frame 231 .

[0055] By setting the placement frame 231, the test sample 10 matching the inner cavity size of the placement frame 231 is placed in the placement frame 231. The placement frame 231 can limit the test sample 10 and prevent the test sample 10 from slipping during the test, thereby ensuring the placement stability of the test sample 10 during the test.

[0056] Further explained, the driving mechanism 3 includes a driving electric cylinder 31 and a connecting plate 32, the lower end surface of the test platform 2 is connected with a connecting rod 25, the connecting rod 25 is connected to the left side of the test platform 2, and the connecting rod 25 is vertically arranged, the cylinder body of the driving electric cylinder 31 is hinged to the right side of the support frame 1, the piston rod of the driving electric cylinder 31 is fixedly connected to one end of the connecting plate 32, and the other end of the connecting plate 32 is fixedly connected to the end of the connecting rod 25 away from the test platform 2.

[0057] By setting the driving electric cylinder 31 and the connecting plate 32, the driving electric cylinder 31 is started. Since the cylinder body of the driving electric cylinder 31 is hinged to the support frame 1, the piston rod of the driving electric cylinder 31 contracts, the cylinder body of the driving electric cylinder 31 rotates, and the piston rod of the driving electric cylinder 31 drives the connecting plate 32 to move to the lower right, thereby driving the connecting rod 25 to move downward, so as to drive the test platform 2 to rotate, thereby changing the inclination angle of the test platform 2.

[0058] like Figure 8 As shown, specifically, the support frame 1 is provided with a second articulated seat 11, the second articulated seat 11 is provided with a second rotating shaft 111, the end of the linear motor 41 away from the pressure sensor 42 is provided with a second connecting seat 411, the second connecting seat 411 is provided with a second through hole 4111 matching the second rotating shaft 111, the second rotating shaft 111 is inserted into the second through hole 4111 and is hinged to the second connecting seat 411;

[0059] The right end surface of the second articulated seat 11 is connected to a limited rotation rod 112 . The limited rotation rod 112 extends downward and protrudes from the lower end surface of the second connecting seat 411 . The limited rotation rod 112 abuts against the right end surface of the linear motor 41 .

[0060] By setting the second hinge seat 11 on the support frame 1 and the second connecting seat 411 on the linear motor 41, the linear motor 41 is hinged to the support frame 1, and the linear motor 41 can rotate freely with the center of the second rotating shaft 111 as the rotation center. By setting the rotation limit rod 112, the linear motor 41 can be limited to rotate to the right. Fig. 9As shown, when the test shoe 43 slides, it will slide to the left, which is convenient for observing the sliding condition of the test shoe 43. When the test shoe 43 needs to be reset, the right end face of the linear motor 41 can be abutted against the limiting rod 112 to facilitate resetting the test shoe 43.

[0061] like Figure 4 As shown, it is further explained that the support frame 1 is respectively provided with a third connecting seat 12 on both sides of the width direction of the test platform 2, and the two ends of the width direction of the test platform 2 are respectively connected with a third rotating shaft 26, and the third rotating shaft 26 is rotatably set on the third connecting seat 12, and one of the third rotating shafts 26 is fixedly connected to the angle encoder 21.

[0062] Specifically, the third connecting seat 12 is provided with a third through hole, and the third rotating shaft 26 rotatably passes through the third through hole, wherein one of the third rotating shafts 26 is fixedly connected to the angle encoder 21 after passing through the third through hole.

[0063] By setting the third connecting seat 12, the rotational connection between the test platform 2 and the support frame 1 is realized. Specifically, a bearing is set in the third through hole, and the third rotating shaft 26 is connected to the third connecting seat 12 through the bearing. One of the third rotating shafts 26 passes through the third through hole and is fixedly connected to the angle encoder 21. The angle encoder 21 follows the test platform 2 to make a rotational motion to test the inclination angle of the test platform 2.

[0064] Specifically, the tread anti-slip performance testing device further includes a control cabinet 5 , and the control cabinet 5 is fixedly arranged on the support frame 1 .

[0065] By setting the control cabinet 5, the tread anti-skid performance test device can be operated and controlled. Specifically, the linear motor 41, the pressure sensor 42, the angle encoder 21, the linear module 22 and the driving electric cylinder 31 are electrically connected to the control cabinet 5 respectively, and the control cabinet 5 can be used to control the operation of the linear motor 41, the linear module 22 and the driving electric cylinder 31, thereby controlling the movement of the test shoe 43, controlling the position of the test shoe 43 stepping on the surface of the test sample 10 and controlling the inclination angle of the test sample 10, so as to realize automatic testing. The control cabinet 5 can also obtain the value of the pressure sensor 42 and the value of the angle encoder 21, and record the obtained values ​​for evaluating the tread anti-skid performance of the tread of the tread panel.

[0066] Preferably, an adjusting foot cup 13 is provided at the bottom of the supporting frame 1 , and the adjusting foot cup 13 is provided at a corner of the supporting frame 1 .

[0067] By providing the adjusting foot cup 13, the height of the support frame 1 can be adjusted by the adjusting foot cup 13, so as to facilitate operators to perform operations such as test sample placement, test control, inspection and maintenance on the tread anti-slip performance testing device.

These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way.
