Description

Technical Field

[0001] The utility model relates to the field of detection technology, in particular to a scraper strip wear testing device. Background Art

[0002] In the current field of sweeper blade testing, traditional testing methods still generally rely on manual operation. Specifically, this process involves testers holding the blade directly and rubbing it back and forth on different types of floors to evaluate its wear resistance, cleaning effect and service life. Although this method is intuitive, it has many limitations in actual application.

[0003] First, from the perspective of efficiency, manual testing is extremely time-consuming and labor-intensive. Each scraper needs to go through a repetitive and laborious friction process to collect data on the degree of wear and cleaning efficiency, which is undoubtedly a bottleneck for mass production or rapid verification of new scrapers. In addition, manual testing is difficult to achieve a continuous and uninterrupted working mode, further reducing the overall testing efficiency.

[0004] Secondly, the influence of subjective judgment cannot be ignored. Since the test results largely rely on the operator's perception and experience, different people performing the same test may come to different conclusions, which leaves doubts about objectivity and accuracy, and greatly reduces the consistency and comparability of the test results.

[0005] Furthermore, safety and labor intensity are also issues that cannot be ignored. Long-term manual friction testing not only poses a challenge to the physical strength of testers, but may also cause occupational health problems such as hand fatigue and wear and tear due to improper operation.

[0006] In view of the above background, it is particularly important to explore and develop more advanced and efficient scraper blade testing technology. The ideal alternative should be able to automate the test process, reduce human dependence, and ensure the accuracy and repeatability of the test results, providing a more scientific and systematic method support for the performance optimization and quality control of the scraper blade of the sweeper.

[0034] Specifically, the shape of the conveyor belt 2 of this embodiment is as follows: Figure 1 and Figure 2 As shown, the test mechanism 23 can be driven to rotate back and forth. For example, two test mechanisms 23 are installed on the conveyor belt 2. The movement of the conveyor belt 2 drives the test mechanism 23 to move, so that the scraper of the test mechanism 23 located below can rub against the ground to test the wear performance of the scraper. Among them, the conveyor belt 2 can be selected from the existing technology, and a fixed hole position is set. The mounting seat 3 of the test mechanism 23 can be locked in the corresponding hole position of the conveyor belt 2 by screws, bolts and other parts.

[0035] like Figures 3 to 6As shown, the test mechanism 23 of this embodiment includes a mounting seat 3 and a height adjustment component mounted on the mounting seat 3. The height adjustment component is used to adjust the height of the scraper strip, so as to adjust the contact force between the scraper strip and the ground and adjust the friction. As an implementation method of this embodiment, the height adjustment component includes a height adjustment control member 4, a base 5 and a lifting seat 6. The scraper strip is mounted on the lifting seat 6. Side plates 7 are mounted on both sides of the mounting seat 3. An installation space is formed between the two side plates 7. The base 5 is provided with a first inclined surface 8. The bottom of the lifting seat 6 is provided with a second inclined surface 9. The first inclined surface 8 is in contact with the second inclined surface 9. The base 5 and the lifting seat 6 are both located in the installation space.

[0037] Specifically, the staff changes the position of the base 5 through the height adjustment control member 4 according to the actual height requirement of the scraper strip, and the first inclined surface 8 of the base 5 cooperates with the second inclined surface 9 of the lifting seat 6. Figure 8When the base 5 moves to the right, the lifting seat 6 will rise, and the lifting seat 6 will drive the scraper to rise; when the base 5 moves to the left, the lifting seat 6 will move down, driving the scraper to move down, so as to achieve the purpose of adjusting the height of the scraper.

Among them, the adjustment member 16 can be optionally a knob, and the adjustment member 16 is passed through the side plate 7 and abutted against the tension plate 18, and the adjustment member 16 is screwed to the side plate 7. After rotating the adjustment member 16, the adjustment member 16 can push the tension plate 18 to move, thereby changing the spacing between the tension plate 18 and the fixed plate 17, that is, changing the tightness of the scraper strip.

[0041] Among them, Figure 5 , Figure 6 as well as Fig.10 As shown, the lifting seat 6 is provided with a T-shaped slot 20, and the bottom of the elastic plate 18 is provided with a first T-shaped block 21, and the first T-shaped block 21 is slidably assembled in the T-shaped slot 20; the bottom of the fixed plate 17 is provided with a second T-shaped block 22, and the second T-shaped block 22 is assembled in the T-shaped slot 20.
