Technical Field
[0001] This utility model relates to the field of durability testing equipment, and more specifically, to a durability testing device for tires of aerial work platforms. Background Technology
[0002] After a period of use, the rubber wheels of aerial work platforms may experience wear or aging. In particular, after a collision, pieces of rubber may come off, affecting normal use and, in severe cases, impacting the stability of the aerial work platform and posing a certain risk to the user's work safety.
[0003] After reviewing the literature, it was found that current vehicle durability testing is time-consuming and labor-intensive, and the cost and operating costs of conventional testing equipment are relatively high. In addition, because the obstacle positions of some existing testing equipment are fixed, the device cannot simulate the friction phenomenon of tires under different environments, such as gravel roads with a gravel height of 10-20mm and speed bumps with a height of 20mm. This reduces the comprehensiveness of the test data. Therefore, we have made improvements and proposed a tire durability testing device for aerial work platforms. Utility Model Content

[0028] Example 1
[0029] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 A durability testing device for aerial work platform tires includes a workbench 1, which is an existing structure and will not be described in detail here. A turntable 2 is provided on the top of the workbench 1. The turntable 2 can be rotated by an external power device. The top of the workbench 1 can hold the aerial work platform and place the tire on the top of the turntable 2, so that the turntable 2 can perform durability testing on the aerial work platform tires. An adjustment groove 3 is provided on the top of the turntable 2. A moving block 6 is slidably connected inside the adjustment groove 3. A support plate 9 is fixedly connected to one side of the moving block 6. A moving groove 7 is provided on the top of the turntable 2. The surface of the support plate 9 is slidably connected to the inside of the moving groove 7. A guide groove 10 is provided on the top of the moving block 6. A transmission adjustment device is provided inside the guide groove 10.
[0030] The transmission adjustment device includes a connecting frame 18, the surface of which is slidably connected to the inside of the guide groove 10. The cross-section of the connecting frame 18 is U-shaped. The top of the moving block 6 is provided with a mounting plate 8, and the inside of the mounting plate 8 is provided with a sliding adjustment groove 14. The surface of the connecting frame 18 is slidably connected to the inside of the sliding adjustment groove 14. An obstacle block 15 is fixedly connected to the top of the connecting frame 18. The obstacle block 15 can rub the tire and enable the device to test the tire. An extension plate 17 is fixedly connected to one side of the mounting plate 8. The extension plate 17 is fixedly installed on the top of the support plate 9 by bolts, which fixes the position of the mounting plate 8 and the obstacle block 15 and makes the installation and disassembly of the mounting plate 8 more convenient.
[0031] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the top of the movable block 6 is provided with a mounting positioning groove 12, and the bottom of the mounting plate 8 is fixedly connected with a mounting positioning block 13. The surface of the mounting positioning block 13 is slidably connected to the inside of the mounting positioning groove 12. The cross-sections of the mounting positioning block 13 and the mounting positioning groove 12 are both trapezoidal. Through the mutual cooperation of the mounting positioning groove 12 and the mounting positioning block 13, the positioning and installation of the mounting plate 8 is more convenient.
[0032] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a protrusion 5 is fixedly connected to the top of the turntable 2. The position of the protrusion 5 is fixed so that the tire can be subjected to routine durability tests. The inside of the adjustment groove 3 is rotatably connected to a threaded rod 4 extending to the outside of the turntable 2. The surface of the threaded rod 4 is connected to the internal thread of the moving block 6. The position of the moving block 6 can be adjusted by the operator rotating the threaded rod 4. At the same time, the position of the moving block 6 can be fixed again by bolts passing through the inside of the support plate 9, so that the position of the moving block 6 is more stable.
[0033] Example 2
[0034] The aerial work platform tire durability testing equipment provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the lower surface inside the guide groove 10 is inclined, so that when the connecting frame 18 moves inside the guide groove 10, the lower surface inside the guide groove 10 can cause the connecting frame 18 to move upward, thereby adjusting the height of the obstacle block 15 and enabling the device to simulate different road conditions, thus improving the range of application of the device and enabling the device to test tires more comprehensively.
[0035] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a limiting groove 11 is provided inside the guide groove 10. The limiting groove 11 is inclined and is set inside the guide groove 10. The limiting groove 11 is parallel to the lower surface of the guide groove 10. A limiting block 16 is fixedly connected to the side of the connecting frame 18 near the limiting groove 11. The surface of the limiting block 16 is movably connected to the inside of the limiting groove 11. The limiting block 16 can move inside the limiting groove 11. Through the cooperation of the limiting groove 11 and the limiting block 16, the connecting frame 18 can move more smoothly. At the same time, the position of the connecting frame 18 is restricted, and the connecting frame 18 can cooperate more smoothly with the sliding adjustment groove 14, making the position adjustment of the device more convenient.
[0036] The usage process of the aerial work platform tire durability testing equipment provided by this utility model is as follows: The worker places the aerial work platform on the top of the workbench 1 and the tire on the top of the turntable 2, so that the turntable 2 can perform durability testing on the aerial work platform tire. The worker rotates the threaded rod 4, which can adjust the position of the moving block 6. Through the cooperation of the mounting positioning groove 12 and the mounting positioning block 13, the positioning and installation of the mounting plate 8 is more convenient. The obstacle block 15 can rub against the tire, and the device can test the tire. At the same time, because the lower surface inside the guide groove 10 is inclined, when the connecting frame 18 moves inside the guide groove 10, the lower surface inside the guide groove 10 can make the connecting frame 18 move upward, and the height of the obstacle block 15 can be adjusted. The device can simulate different road conditions, thereby improving the application range of the device and enabling the device to test the tire more comprehensively.
