[0002] Aerial work platforms are widely used in modern construction, maintenance, and other fields, and their safety is of paramount importance. Among these, the wheels are a key component, and their rigidity directly affects the platform's stability and operational safety. Therefore, the rigidity of the wheels must be tested before installation and use.

[0003] However, existing technologies typically involve long testing cycles and require bolt-mounted wheels for testing, which greatly increases the labor intensity of workers and is time-consuming and labor-intensive. Therefore, a wheel stiffness testing device for aerial work platforms has been proposed. Utility Model Content

[0007] As a preferred technical solution of this application, a first support plate is fixedly connected to one side of the fixing frame, and a first electric telescopic rod is fixedly connected to one side of the first support plate.

[0008] As a preferred technical solution of this application, a pressure sensor is fixedly connected to the output end of the first electric telescopic rod, and a first limiting block is fixedly connected to the output end of the pressure sensor.

[0010] As a preferred technical solution of this application, a control box is provided at the bottom of the fixing frame, and a control panel is fixedly connected to the back of the fixing frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In this application's solution: during use, the output end of the second electric telescopic rod is controlled via the control panel to move the first thrust ball bearing and pressure block downwards, applying pressure to the upper surface of the rubber wheel and limiting its position. Then, the first electric telescopic rod is driven by the control panel to move the pressure sensor, the first limiting block, and the rotating column to the right, making the rotating column in close contact with the surface of the rubber wheel.

A rubber wheel 6 is provided on the upper surface of the second limiting block 16. The second limiting block 16 is used to limit the position of the rubber wheel 6. The upper surface of the rubber wheel 6 is in contact with the lower surface of the pressure block 10. The pressure block 10 and the second limiting block 16 work together to limit the position of the rubber wheel 6.

[0025] Furthermore, such as Figure 3 , Figure 5 As shown, a motor 7 is fixedly connected to the upper surface of the workbench 14. The output end of the motor 7 is fixedly connected to a first gear 8 through a coupling. The outer surface of the first gear 8 meshes with the outer surface of the second gear 9. The motor 7 drives the first gear 8 to rotate.

[0026] Furthermore, such as Figure 1 , Figure 3 As shown, a first support plate 2 is fixedly connected to one side of the fixed frame 1, and a first electric telescopic rod 3 is fixedly connected to one side of the first support plate 2. The first support plate 2 serves to limit the position of the first electric telescopic rod 3.

[0027] Furthermore, such as Figure 3 , Figure 5 As shown, a pressure sensor 21 is fixedly connected to the output end of the first electric telescopic rod 3, and a first limit block 4 is fixedly connected to the output end of the pressure sensor 21.

[0030] The usage process of the wheel stiffness testing device for aerial work platforms provided by this utility model is as follows: First, place the rubber wheel 6 on the upper surface of the second limiting block 16, so that the second limiting block 16 engages with the inner wall of the rubber wheel 6, limiting the position of the rubber wheel 6. Then, control the second electric telescopic rod 12 via the control panel 18 to move it, causing the output end of the second electric telescopic rod 12 to drive the first thrust ball bearing 11 and the pressure block 10 downwards until the lower surface of the pressure block 10 is in close contact with the upper surface of the rubber wheel 6, thus limiting and fixing the rubber wheel 6. Then, drive the first electric telescopic rod 3 via the control panel 18 to move it, using the first electric telescopic rod 3 to drive the pressure sensor 21, the first limiting block 4, and the rotating column 5 to move to the right until the rotating column 5 engages with the rubber wheel 6. The surface of the rubber wheel 6 is in close contact. Based on the feedback signals from the laser displacement sensor 20 and the pressure sensor 21, the current load value and distance are determined. Simultaneously, the motor 7 is started, which drives the first gear 8 to rotate, causing the first gear 8 to mesh with the second gear 9. The second gear 9 then drives the rubber wheel 6 to rotate, simulating the working state of the rubber wheel 6 during high-altitude operations. The first limit block 4 and the rotating column 5 continue to move, applying pressure to the surface of the rubber wheel 6 and recording the data. This process serves to quickly fix the rubber wheel 6 and apply test pressure through the second electric telescopic rod 12 and the first electric telescopic rod 3, increasing detection efficiency. By rotating the rubber wheel 6, the working state during high-altitude operations is simulated, ensuring the accuracy of the experimental data.
