Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of detection, more particularly, it relates to a floor wear resistance test device and a test method thereof. BACKGROUND

[0002] The wear resistance of floor materials is one of the important indicators for evaluating the quality of materials. However, the existing floor wear resistance tester has many limitations in the experimental process. The traditional floor wear resistance tester usually adopts a single circular motion mode, so that the experimental pressure roller can only move in a circular motion by the driving motor during the test. The movement path is single and fixed. This movement mode cannot fully simulate the complex wear conditions of floor materials in actual use, such as different direction friction, pressure changes, and different angle and curvature movement paths.

[0003] In addition, the test pressure on the ground during the test of the existing floor wear resistance tester is also fixed, which cannot simulate the dynamic pressure changes generated when different gravity objects are dragged on the floor in actual use. These factors limit the accuracy of the test results of the traditional floor wear resistance tester, and cannot fully and truly reflect the wear resistance of the floor material.

[0004] In order to solve the above problems, a floor wear resistance test device and a test method thereof are provided. SUMMARY

DETAILED DESCRIPTION

[0039] It should be noted that the embodiments and the features in the embodiments in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0040] It should be noted that, unless otherwise specified, all the technical and scientific terms used in the present application have the same meaning as that generally understood by the ordinary skilled person in the technical field to which the present application belongs.

[0041] In the present application, unless otherwise specified, the orientation such as "upper", "lower" is generally directed to the direction shown in the drawings, or is directed to the vertical, perpendicular or gravity direction; similarly, for the convenience of understanding and description, "left", "right" is generally directed to the left and right shown in the drawings; "inner", "outer" refers to the inner and outer relative to the contour of each component itself, but the above orientation words are not used to limit the present application.

[0042] Embodiment, please refer to Figure 1 - Figure 7 A floor wear resistance test device and a test method thereof, comprising a support base 1, and a driving motor 2 is fixedly installed at the top end of the support base 1, a transmission chamber 101 is formed in the bottom of the support base 1, and a transmission mechanism 3 and a heave mechanism 4 are arranged inside the transmission chamber 101, the driving motor 2 is connected with a pressure roller mechanism 5 through the transmission mechanism 3, and when the pressure roller mechanism 5 rotates with the transmission mechanism 3, the top end floats up and down by abutting against the heave mechanism 4 to change the test pressure on the ground;

[0043] The transmission mechanism 3 comprises a compound path assembly 6 arranged at the bottom end inside the transmission chamber 101, and a reduction gear assembly 7 arranged above the compound path assembly 6 and engaged with the undulating mechanism 4.

[0044] Nowadays, the floor wear resistance tester can only make the compression roller mechanism 5 move in a circular motion by the driving motor 2 during the experiment, and the movement path is relatively single, which cannot simulate the complex wear condition of the floor material in actual use, such as different direction friction and pressure change. This single movement mode may cause a large deviation between the test data and the actual wear resistance in use, so it cannot comprehensively evaluate the wear resistance of the floor.

[0045] In the present application, the support base 1 is provided with a mounting hole, and the support base 1 is fixedly installed on the ground to be tested through the mounting hole by bolts. The driving motor 2 is provided with a connecting head of a control device, and the control device is electrically connected with the driving motor 2 through wires, and then the driving motor 2 is controlled to rotate, so as to drive the compression roller mechanism 5 to rotate in multiple directions and angles on the ground to be tested, thereby simulating the friction in actual use. The wear marks and friction depth generated by the compression roller mechanism 5 rotating in multiple directions and angles on the ground to be tested are analyzed to determine the wear resistance of the floor in actual use.

[0046] Specifically, the transmission mechanism 3 and the undulating mechanism 4 are arranged in the transmission chamber 101 in an up-down distribution, and the undulating mechanism 4 is arranged above the transmission mechanism 3. The output shaft of the driving motor 2 is connected with the compound path assembly 6, and the compression roller mechanism 5 and the compound path assembly 6 are arranged in an active plug-in mode. After the support base 1 is fixed on the ground, the bottom end of the compression roller mechanism 5 generates a certain pressure value on the ground. When the driving motor 2 drives the compression roller mechanism 5 to rotate through the compound path assembly 6, the walking path of the compression roller mechanism 5 on the ground is irregular, thereby simulating the wear condition of the ground in actual use. When the compound path assembly 6 drives the compression roller mechanism 5 to move, the top end of the compression roller mechanism 5 always abuts against the undulating surface of the undulating mechanism 4, so that the compression roller mechanism 5 is pushed by the undulating surface of the undulating mechanism 4 when it moves, thereby making the compression roller mechanism 5 float up and down, and changing the test pressure of the compression roller mechanism 5 on the ground, so as to simulate the wear of the ground under different pressures in actual use.

[0047] Further, the driving motor 2 drives the undulating mechanism 4 to rotate through the reduction gear assembly 7, so that the undulating mechanism 4 slowly rotates in the transmission chamber 101, and the rotation speed of the undulating mechanism 4 and the rotation speed of the compound path assembly 6 exist a proportional difference. Through the proportional difference of the rotation speed, the pressure at the same position of each circle of the circular rotation of the compression roller mechanism 5 is not the same, thereby making the same position simulate the different pressure wear in actual use, so as to make the floor wear resistance test more consistent with the actual situation.

[0048] The support base 1 comprises a support disc 102 provided with a transmission chamber 101, a support frame 103 arranged on the circumferential sidewall of the support disc 102, and a counterweight disc 104 arranged at the top end of the support disc 102.

[0049] The counterweight disc 104 is provided with counterweight blocks 105.

[0050] The support frame 103 is welded to the circumferential sidewall of the support disc 102, and the bottom end of the support frame 103 is provided with mounting holes for fixation. The support disc 102 is supported by the support frame 103 and forms a wear-resistant test area of the compression roller mechanism 5 with the ground. The drive motor 2 is fixedly installed at the center position of the counterweight disc 104, and the output shaft of the drive motor 2 penetrates the counterweight disc 104 and the top end of the support disc 102 into the transmission chamber 101, thereby being connected with the composite path assembly 6. The bottom end of the support disc 102 is provided with an avoidance through hole communicating with the transmission chamber 101, and the diameter of the avoidance through hole is smaller than the maximum diameter of the composite path assembly 6, thereby being able to support and limit the composite path assembly 6. At the same time, the bottom end of the compression roller mechanism 5 is attached to the ground, and the top end is inserted into the composite path assembly 6. Through the design of the avoidance through hole, the compression roller mechanism 5 can rotate with the composite path assembly 6.

[0051] Further, the counterweight blocks 105 are provided with four blocks, and each of the counterweight blocks 105 is provided with a handle for taking and disassembling. The counterweight disc 104 is provided with a limiting protrusion, and the bottom of the counterweight block 105 is provided with a limiting groove corresponding to the limiting protrusion, so that the counterweight block 105 can be stably counterweighted in a ring shape after being placed on the counterweight disc 104, thereby improving the stability of the equipment.

[0052] The composite path assembly 6 comprises a center gear 601 fixedly connected with the output shaft of the drive motor 2, and a plurality of planetary gears 602 arranged at the outer circle of the center gear 601 and engaged with the center gear 601.

[0053] A plurality of tooth blocks 106 are arranged in an annular array on the inner wall of the transmission chamber 101, and the annular array of tooth blocks 106 is engaged with the planetary gears 602.

[0054] The planetary gears 602 are provided with a rotation-stopping insertion hole 603 at the center, and the compression roller mechanism 5 is movably inserted into the rotation-stopping insertion hole 603.

[0055] The diameter of the center gear 601 is smaller than the diameter of the planetary gears 602, thereby achieving the effect of deceleration, avoiding the engagement of the center gear 601 with the planetary gears 602 when the drive motor 2 rotates at high speed, and thereby avoiding the high-speed movement of the compression roller mechanism 5 on the floor. Although rapid rotation can complete more tests in a short time, it may not fully reflect the wear resistance of the floor in actual use. For example, rapid rotation may cause the material to be insufficiently filled or compacted, thereby affecting the accuracy of the test results.

[0056] The central gear 601 drives multiple planetary gears 602 through meshing to revolve around the central gear 601, and the multiple planetary gears 602 revolving mesh with the annular array of the first tooth block 106 on the inner wall of the transmission chamber 101, so that the planetary gears 602 revolve and rotate at the same time, thereby enabling the compression roller mechanism 5 inserted on the planetary gears 602 to realize the combination of the two running paths of revolution and rotation. Through the coupling of revolution and rotation, the compression roller mechanism 5 can cover a larger area and simulate different angles and curvatures of the moving path, so that the wear of the compression roller mechanism 5 on the ground is more realistic, and the wear resistance is more accurate.

[0057] The compression roller mechanism 5 includes a rotation-stopping column 501 movably inserted into the rotation-stopping insertion hole 603, a rotating disc 502 arranged at the bottom end of the rotation-stopping column 501, and multiple compression wheels 503 arranged in an annular array at the bottom end of the rotating disc 502.

[0058] The multiple compression wheels 503 are universal wheels that can adaptively adjust the angle according to the revolution and rotation, thereby ensuring that the compression wheels 503 can normally roll. If the compression wheels 503 are directional wheels, the rotation of the planetary gears 602 will cause individual compression wheels 503 in the annular array to not normally rotate in the opposite direction of the revolution, thereby causing the compression wheels 503 to be easily damaged.

[0059] The compression roller mechanism 5 further includes a movable groove 504 opened at the top end of the rotation-stopping column 501, and a return spring 505 and a top rod 506 arranged in the movable groove 504.

[0060] The top end of the top rod 506 abuts against the undulating mechanism 4.

[0061] The top rod 506 abuts against the undulating mechanism 4, thereby compressing the return spring 505, so that the reaction force of the return spring 505 pushes the rotation-stopping column 501 to move downward, thereby driving the rotating disc 502 and the multiple compression wheels 503 to abut against the ground. When the driving motor 2 drives the multiple compression roller mechanisms 5 to rotate through the composite path assembly 6 for testing, the planetary gears 602 revolve in the transmission chamber 101, thereby enabling the inserted compression roller mechanism 5 to also revolve. When revolving, the top rod 506 abuts against the undulating surface of the undulating mechanism 4, thereby changing the compression state of the return spring 505 according to the undulating surface, so as to generate different pressures on the ground surface by the multiple compression wheels 503 revolving and rotating, thereby simulating the wear of different gravity objects on the ground.

[0062] It should be pointed out that the top end side wall of the rotation stopping column 501 is provided with a anti-drop block, and the top end of the rotation stopping plug hole 603 is provided with a pressing groove, the anti-drop block and the pressing groove are movably matched, in the initial state, the anti-drop block is located at the upper end of the pressing groove, and the lower end of the pressing groove still leaves a downward space for the anti-drop block, and the interval of the downward space is greater than the height difference between the highest point and the lowest point of the undulating surface in the undulating mechanism 4.

[0063] The undulating mechanism 4 comprises an undulating plate 401 arranged above the planetary gear 602, and a pad plate 402 arranged between the undulating plate 401 and the planetary gear 602.

[0064] The undulating plate 401 and the pad plate 402 have the same diameter and are rotationally matched with the annular array of the first tooth block 106 in the transmission chamber 101, the bottom end of the undulating plate 401 is provided with a corrugated surface 403, and the annular array of the pad plate 402 is provided with a via hole 404 matched with the plug-in of the top rod 506.

[0065] The top rod 506 penetrates the via hole 404 and abuts against the corrugated surface 403 at the bottom end of the undulating plate 401 under the action of the reset spring 505, and the arrangement of the pad plate 402 makes the central gear 601 and the plurality of planetary gears 602 have better stability during driving.

[0066] The speed reduction gear assembly 7 comprises a first speed reduction gear 701 arranged on the output shaft of the driving motor 2, and a second speed reduction gear 702 rotationally installed on the top end of the inner wall of the transmission chamber 101.

[0067] The undulating plate 401 is provided with a transmission avoiding hole 405 in the center, and the inner wall of the transmission avoiding hole 405 is provided with an annular array of second tooth blocks 406 meshing with the second speed reduction gear 702.

[0068] The diameter of the first speed reduction gear 701 is smaller than that of the second speed reduction gear 702, and the transmission ratio of the first speed reduction gear 701 meshing with the second tooth block 406 through the second speed reduction gear 702 is smaller than that of the central gear 601 meshing with the planetary gear 602.

[0069] When the compression wheel 503 performs a compound path motion, the arrangement of the speed reduction gear assembly 7 makes the undulating plate 401 rotate, so that the fixed point of each circle of the top rod 506 is different in position and receives different pressure on the ground floor during each circle rotation, thereby enhancing the randomness of the wear resistance test and making the test result more consistent with the actual wear resistance effect.

[0070] The bottom end of the central gear 601 is provided with a anti-drop plate 8, and the diameter of the anti-drop plate 8 is smaller than the minimum diameter of the circle formed by the plurality of rotation stopping columns 501 on the annular array of planetary gears 602.

[0071] The anti-detachment plate 8 and the inner wall of the bottom of the transmission chamber 101 provide limiting support for multiple planetary gears 602, thereby improving the stability of the transmission.

[0072] S1. Fix the floor abrasion resistance testing device onto the ground to be tested through the mounting holes on the support base 1, ensuring that the pressure roller mechanism 5 is in close contact with the ground, and connect the drive motor 2 through the control equipment;

[0073] S2. According to the test requirements, set the parameters of the speed of the drive motor 2, the initial pressure of the pressure roller mechanism 5 on the ground, and the test duration.

[0074] S3. Start the drive motor 2 to drive the composite path component 6 to operate, thereby causing the pressure roller mechanism 5 to rotate in multiple directions on the ground to be tested. During the rotation, the pressure roller mechanism 5 will float up and down with the change of the corrugated surface 403 because the top end is always in contact with the undulating surface of the undulating mechanism 4, thereby changing the test pressure on the ground, simulating different pressure wear conditions in actual use, and thus judging and analyzing the wear resistance performance of the floor.

[0075] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
