[0025] 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.

[0026] Please see Figures 1-4 A water-based polyurethane floor mortar abrasion resistance testing instrument includes a frame 1. A handle 11 is uniformly and fixedly installed on the top of the frame 1 in a circular shape. A fixing ring 2 is fixedly sleeved on the outer bottom ring of the frame 1. A motor 3 is fixedly installed on the top of the frame 1 between the handles 11. A transmission groove is opened inside the frame 1. The output shaft of the motor 3 is located inside the transmission groove. A transmission block 31 is rotatably sleeved at the bottom of the transmission groove. A toothed head is provided on the top of the transmission block 31. A groove matching the toothed head is opened at the end of the output shaft of the motor 3. The output shaft of the motor 3 is engaged with the outer ring of the toothed head. A universal coupling 32 is fixedly connected to the bottom of the transmission block 31. A base plate 33 is provided at the bottom of the universal coupling 32. A quick-release column 34 is provided on the top of the base plate 33. The bottom of the universal coupling 32 is fixedly connected to the top of the quick-release column 34. A symmetrical plate 35 is uniformly and circularly installed on the bottom of the base plate 33. A grinding wheel 36 is rotatably sleeved inside the symmetrical plate 35.

[0027] The base plate 33 has a water tank inside (not shown in the figure), and a drainage hole (not shown in the figure) is opened at the bottom of the base plate 33 at the grinding wheel 36. After the water tank is filled with water, the motor 3 is started, and the motor 3 drives the base plate 33 to rotate, so that the grinding wheel 36 makes contact friction with the ground. When the base plate 33 rotates, the centrifugal force will throw the water in the water tank out through the drainage hole, so that the water drips evenly on the grinding wheel 36, increasing the contact area between the grinding wheel 36 and the ground, and increasing the friction between the grinding wheel 36 and the ground.

[0028] The symmetry plate 35 is detachably installed at the bottom of the base plate 33. The grinding wheel 36 is movably installed inside the symmetry plate 35. The connection between the grinding wheel 36 and the symmetry plate 35 is detachable. Different friction media can be installed inside the symmetry plate 35. The friction media on the market are not limited to the grinding wheel 36. For example, sandpaper, fine sand, etc. The grinding wheel 36 can be replaced with sandpaper, fine sand, etc. After the symmetry plate 35 and the grinding wheel 36 are disassembled, the fine sand medium is placed between the base plate 33 and the floor grinding block, and friction is performed using the fine sand medium.

[0029] A data monitoring device is located above the cabinet 1, between the motor 3 and the handle 11. This device is not shown in the figure. It is existing technology and is connected to an external device via a data connection cable. Wear and other data can be measured by the data monitoring device. This solution will not describe the existing technology in detail.

[0030] By setting a fixed ring 2 to adapt to different ground angles, the device provides reliable support for the whole. The universal coupling 32 allows the base plate 33 to be stably attached to the ground at different angles. The tilt of the base plate 33 in any direction can be adjusted by the universal coupling 32. During rotation, it provides a stable driving force. After setting the connection between the quick-release column 34 and the universal coupling 32, the base plate 33 can be quickly replaced. This allows the device to replace base plates 33 of different sizes and shapes in different environments. Users can achieve more stable results and more accurate data during wear resistance testing.

[0031] Please see Figures 1-3 The bottom of the fixed ring 2 is uniformly fixed with support legs 21. The bottom of the support legs 21 is movably mounted with anti-slip plate 22. The top of the anti-slip plate 22 is movably mounted with stud A23. The outer ring of stud A23 is threaded. The support legs 21 have a threaded groove inside. The shape of the stud A23 matches the internal threaded groove of the support legs 21. The bottom of stud A23 is provided with a ball. The top of the anti-slip plate 22 is provided with a ball sleeve. The ball is located inside the ball sleeve. The ball sleeve can move around the outer ring of the ball. The ball sleeve is movably fitted onto the outer ring of the ball.

[0032] By rotating the stud A23 inside the support leg 21, the overall height of the device can be adjusted, allowing the bottom surface of the paved floor to make stable contact with the grinding wheel 36. Furthermore, the anti-slip plate 22 can rotate in a corresponding manner around the outer ring of the ball at the bottom of the stud A23, enabling the device to operate stably even when placed on an inclined surface.

[0033] Please see Figures 1-4The universal coupling 32 includes an upper shaft 321 and a lower shaft 322. The upper shaft 321 is fixedly connected to the bottom of the transmission block 31, and the lower shaft 322 is fixedly connected to the top of the quick-release column 34. A connecting shaft 323 is movably connected between the upper shaft 321 and the lower shaft 322. By adjusting the position of the quick-release column 34, the universal coupling 32 can adjust its angle together with the quick-release column 34, so that the bottom surface of the base plate 33 can be adapted to the grinding surface with different tilt angles.

[0034] Please see Figures 1-4 The quick-release post 34 is fixedly installed with a stud B341 at the top. The lower shaft 322 has a groove inside that matches the stud B341. The shape of the stud B341 matches the groove inside the lower shaft 322. The outer ring of the quick-release post 34 and the outer ring of the lower shaft 322 are evenly provided with a sliding groove 342 in a circular shape. A retaining strip 343 is slidably installed inside the sliding groove 342.

[0035] By sliding the locking strip 343 to the outer ring of the lower shaft 322, rotating the quick-release column 34 can make the quick-release column 34 and the base plate 33 disengage from the lower shaft 322 and fix them in place. For different working conditions, the base plate 33 of different sizes can be replaced for installation with the lower shaft 322, which facilitates disassembly and assembly.

[0036] Working principle: By rotating the stud A23 inside the support leg 21, the overall height of the device is adjusted so that the bottom surface of the grinding wheel 36 is just touching the ground. The anti-slip plate 22 adaptively rotates around the outer ring of the ball, adhering to the ground and providing stable position support for the device. By adjusting the angle of the universal coupling 32, the grinding wheel 36 is fully attached to the ground. The motor 3 is started, and the motor 3 drives the transmission block 31 to rotate through the output shaft. The transmission block 31 drives the quick-release column 34 to rotate together through the universal coupling 32, so that the grinding wheel 36 rotates in a circle on the ground. After the rotation and friction are completed, the wear of the ground is detected to obtain data. Subsequently, according to the user's rotation, the grinding wheel 36 can be removed from the inside of the symmetrical plate 35 and replaced with other friction media, such as sandpaper and fine sand, to measure the effect of different friction media on the ground.
