Description

Technical Field

[0001] This utility model relates to the field of coating abrasion resistance testing technology, and in particular to a device for testing the abrasion resistance of road marking coatings. Background Technology

[0002] A road marking paint abrasion resistance testing device is an experimental instrument used to test the abrasion resistance of paint surfaces. For example, a paint film abrasion tester can simulate the friction between the coating and the external environment in actual use to evaluate the abrasion resistance, aging resistance and performance of the paint under different environmental conditions. This instrument is widely used in industries such as construction, transportation and automobiles, and is especially suitable for durability testing of road marking paint, floor coatings and so on. Its results help guide the quality control and optimization of paint.

[0003] Road marking paint abrasion resistance testing devices, such as paint film abrasion testers, mainly consist of a working turntable, a grinding wheel, a dust collection system, a loading system, and a control panel. The working turntable holds the paint test sample, and the abrasion wheel contacts the paint surface, generating friction through rotation to simulate the wear of the coating in actual use. The loading system controls the applied pressure, and the dust collection system removes particles generated during the test to ensure the accuracy of the test results. The control panel is used to set the rotation speed and number of rotations of the working turntable. In this way, the paint film abrasion tester evaluates the abrasion resistance of the paint under specific conditions, helping to determine the service life and durability of the coating.

[0004] Existing road marking paint abrasion resistance testing devices can effectively evaluate the abrasion resistance performance of paint under specific conditions. However, the counterweights of the loading system are usually fixed to the weighting rod by friction. When the device is running, the weighting rod will be subjected to the vibration force of the grinding wheel, causing the counterweights to move or even fall off, affecting the stability of the counterweights. Therefore, a road marking paint abrasion resistance testing device is proposed to solve the above problems. Utility Model Content

[0032] 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.

[0033] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a road marking paint abrasion resistance testing device, comprising a device housing 1, a weighted rod 2 rotatably connected to the top of the device housing 1 via a rotating seat, a quick-change assembly 4 at the other end of the weighted rod 2, a grinding wheel 3 rotatably connected to the sides of the quick-change assemblies 4 that are close to each other, and a counterweight 5 at the sides of the quick-change assemblies 4 that are far apart from each other, a connecting pipe 7 fixedly connected to the rear side of the device housing 1, a fixing assembly 8 installed on the side of the connecting pipe 7, and a dust collection pipe 21 installed on the side of the vacuum cleaner body 25, one end of the dust collection pipe 21 being connected to the connecting pipe Inside device 7, a working turntable 9 is rotatably connected to the top of the outer casing 1, and a connecting plate 6 is provided on the top of the outer casing 1. The quick-change assembly 4 includes a docking ring 10, which is fixedly connected to the side of the weight rod 2. The counterweight block 5 is connected using the docking ring 10. A fixing ring 11 is fixedly connected inside the weight rod 2. A spring telescopic rod 12 is installed on the side of the fixing ring 11. The spring telescopic rod 12 is an existing component composed of springs and telescopic rods. A pressure plate 13 is fixedly connected to the side of the spring telescopic rod 12. The pressure generated by the cooperation of the fixing ring 11 and the spring telescopic rod 12 causes the pressure plate 13 to move outward. A locking block 16 is fixedly connected inside the counterweight block 5. A sliding groove 14 is opened inside the docking ring 10. The locking block 16 is slidably connected inside the sliding groove 14 and enters the docking ring 10 from the sliding groove 14. The docking ring 10 has a slot 15 inside, and the locking block 16 is engaged with the slot 15. The pressure plate 13 moves outward to press the locking block 16 into the slot 15 and fix the position of the counterweight 5.

[0034] Reference Figure 1 , Figure 4 and Figure 5The fixing component 8 includes a fixing shell 17, which is fixedly connected to the side of the connecting pipe 7 and protects the internal structure. An insert rod 18 is slidably connected inside the fixing shell 17, and a baffle 19 is fixedly connected to the outside of the insert rod 18. Moving the baffle 19 controls the movement of the insert rod 18. A telescopic spring 20 is sleeved around the outer periphery of the insert rod 18, positioned between the fixing shell 17 and the baffle 19. The pressure generated by the cooperation of the baffle 19 and the telescopic spring 20 causes the insert rod 18 to move inward. A slot 22 is provided on the outside of the vacuum cleaner dust collection pipe 21, allowing the insert rod 18 to engage with the slot 22. As the insert rod 18 moves inward, it engages with the slot 22, maintaining the stability of the vacuum cleaner dust collection pipe 21.

[0035] Reference Figure 1 A suction pipe 23 is installed at the bottom of the connecting plate 6, and the bottom of the suction pipe 23 is set on the surface of the working turntable 9. The existing road marking paint abrasion resistance testing device is equipped with an air passage that connects the suction pipe 23 and the dust collection pipe 21 of the vacuum cleaner. The airflow of the vacuum cleaner sucks up the particles generated during operation through the suction pipe 23, so as to avoid affecting the test results. A touch screen 24 is installed on the side of the device housing 1. The speed and number of rotations of the device are controlled through the touch screen 24.

[0036] Working principle: When installing the counterweight 5, the locking block 16 is slid from the slide groove 14 into the docking ring 10. The counterweight 5 is rotated, and the pressure generated by the fixed ring 11 and the spring telescopic rod 12 causes the pressure plate 13 to press the locking block 16 into the locking groove 15. When the counterweight 5 needs to be replaced, the counterweight 5 is moved inward. After the locking block 16 is disengaged from the locking groove 15, the counterweight 5 is rotated to slide the locking block 16 out of the slide groove 14. The currently used counterweight 5 can then be removed and replaced. The above scheme can stably fix the counterweight 5, prevent it from slipping, and also allow for quick replacement of the counterweight 5, thereby improving the stability of the device operation.

[0037] Insert the vacuum cleaner dust collection tube 21 into the connecting tube 7, align the slot 22 with the insertion rod 18, and use the pressure generated by the baffle 19 and the telescopic spring 20 to move the insertion rod 18 inward and lock it into the slot 22, thus fixing the position of the vacuum cleaner dust collection tube 21 and preventing the vacuum cleaner dust collection tube 21 from coming off due to airflow during the vacuuming process, thereby ensuring the stability of the vacuuming system during device operation.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
