[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the following further describes the present invention in conjunction with the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0022] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0023] Embodiment 1: As Figures 1-4 shown, the present invention provides a high-load-bearing wheel operation test mechanism, including an operating panel 1. A support 2 is fixedly installed on the top of the operating panel 1. A driving motor 3 is fixedly installed on the top of the support 2. One side of the outer wall of the driving motor 3 is fixedly installed with a driving rod 4. A limiting plate 5 is fixedly installed on the top of the operating panel 1. The outer surface of the driving rod 4 is movably inserted into the inside of the limiting plate 5. A wheel body 6 is fixedly installed on the outer surface of the driving rod 4. Two strip-shaped columns 7 are rotatably connected to the outer surface of the driving rod 4. Columns 8 are fixedly installed at the tops of the two strip-shaped columns 7. A connecting plate 9 is fixedly installed between the tops of the two columns 8. A load-bearing box 10 is fixedly installed on the top of the connecting plate 9. A plurality of load-bearing blocks 11 are placed at the bottom of the inner wall of the load-bearing box 10.

[0024] The effect achieved by the entire Embodiment 1 is that when it is necessary to test the bearing capacity of the wheel during operation, first start the drive motor 3 installed on the support 2, which drives the drive rod 4 to rotate inside the limit plate 5, thereby driving the wheel body 6 to rotate together with the drive rod 4 to achieve the operation of the wheel. Then, both strip-shaped columns 7 are rotatably connected to the drive rod 4, and columns 8 are installed on both strip-shaped columns 7, and a connecting plate 9 is installed between the tops of the two columns 8. Since two fixing plates 12 are installed on the operation board 1, limit grooves 13 are provided on one outer wall side of the two fixing plates 12, and two L-shaped limit blocks 14 installed at the bottom of the connecting plate 9 are movably embedded in the two limit grooves 13. Thus, when a bearing capacity is applied to the connecting plate 9, a bearing capacity can be applied to the connecting plate 9, the two columns 8, and the two strip-shaped columns 7, and then a downward pressure can be applied to the drive rod 4. Then, by adding load blocks 11 of different weights in the load-bearing box 10, different bearing capacities during the operation of the wheel can be achieved. Secondly, a bracket 15 is also installed on the operation board 1, and a photoelectric sensor 16 is installed on the bracket 15. The photoelectric sensor 16 detects the reflection marks or stripes on the wheel, and by emitting a light beam and receiving the reflected light, the sensor detects the change in light and generates a pulse signal. By analyzing the frequency of the pulse, the rotational speed of the wheel can be calculated, so that the rotational speed data of the wheel before and after the application of the bearing capacity can be detected and compared, thereby realizing the test of the bearing capacity during the operation of the wheel, and improving the use effect of the high-bearing-capacity wheel operation test mechanism.

[0025] Embodiment 2: As Figures 2-4 shown, two fixing plates 12 are fixedly installed on the top of the operation board 1, limit grooves 13 are provided on one outer wall side of the two fixing plates 12, L-shaped limit blocks 14 are movably embedded in the inner surfaces of the two limit grooves 13, and the tops of the two L-shaped limit blocks 14 are fixedly connected to the bottom of the connecting plate 9. A bracket 15 is fixedly installed on the top of the operation board 1, a photoelectric sensor 16 is fixedly installed on the top of the bracket 15, a temperature sensor 17 is fixedly installed on the top of the bracket 15, a controller 18 is fixedly installed on the top of the operation board 1, and one outer wall side of the controller 18 is electrically connected to the outer surface of the photoelectric sensor 16, and one outer wall side of the controller 18 is electrically connected to the outer surface of the temperature sensor 17.

[0026] The effect achieved by the entire Embodiment 2 is that since a temperature sensor 17 is also installed on the bracket 15, and the temperature sensor 17 is also electrically connected to the controller 18, as the increase in temperature is closely related to factors such as the actual load-bearing capacity of the wheel, the thermal stability of the tire material, and the presence of excessive wear or damage, etc., by detecting the temperature difference before and after the wheel runs, if the temperature rises significantly in a short period of time, it indicates that the load-bearing capacity during the wheel's operation is approaching the limit, that is, comparing the temperature data near the wheel before applying the load-bearing capacity and the temperature data near the wheel after applying the load-bearing capacity to further test the load-bearing capacity during the wheel's operation, thereby improving the use effect of the high-load-bearing wheel operation testing mechanism.

[0027] Working principle: First, when it is necessary to test the load-bearing capacity during the wheel's operation, since the rotational speed of the wheel and the temperature change on the wheel surface can be used to test the load-bearing capacity of the wheel, a bracket 15 is installed near the wheel during its operation, and a temperature sensor 17 and a photoelectric sensor 16 are installed on the bracket 15. At this time, the drive motor 3 is started to drive the drive rod 4 and the wheel body 6 to rotate, so as to realize the operation of the wheel. Then, load blocks 11 with a set weight are applied in the load-bearing box 10. Since the load-bearing box 10 is installed on the connecting plate 9, and the two L-shaped limit blocks 14 installed at the bottom of the connecting plate 9 are both movably embedded in the two limit grooves 13, a load-bearing capacity can be applied to the connecting plate 9, the two columns 8, and the two strip-shaped columns 7, and thus a downward pressure can be applied to the drive rod 4, which is equivalent to applying a load-bearing capacity during the wheel's operation. At this time, under the mutual cooperation of the photoelectric sensor 16, the temperature sensor 17, and the controller 18, then comparing the data of the rotational speed of the wheel before applying the load-bearing capacity and the rotational speed after applying the load-bearing capacity, and comparing the temperature data near the wheel before applying the load-bearing capacity and the temperature data near the wheel after applying the load-bearing capacity, the load-bearing capacity during the wheel's operation can be tested, improving the use effect of the high-load-bearing wheel operation testing mechanism.

[0028] The above is only the preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the relevant art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
