A first limiting component 8 is provided inside the movable groove 7. A second limiting component 3 is provided at the bottom of the inner wall of the support frame 2. A control plate 10 is fixedly installed on the front of the right outrigger 4.
[0023] refer to Figure 2 The adjustment assembly 6 includes a dual-head motor 61, a bidirectional screw 62, an adjustment plate 63, and an adjustment groove 64. The dual-head motor 61 is fixedly installed at the bottom of the base 1. The transmission rod of the bidirectional screw 62 is connected to the output end of the dual-head motor 61. The adjustment plate 63 is threadedly connected to the surface of the bidirectional screw 62. The adjustment groove 64 is opened at the top of the base 1 and is provided in two sets. The top of the adjustment plate 63 passes through the adjustment groove 64 from bottom to top and is fixedly connected to the bottom of the movable plate 5.
[0024] As a technical optimization of this utility model, the adjustment component 6 set at the bottom of the base 1 drives the bidirectional screw 62 to rotate through the output end of the double-head motor 61. The rotation of the bidirectional screw 62 drives the adjustment plate 63 to move and adjust inside the adjustment groove 64. When the adjustment plate 63 moves, it drives the moving plate 5 to move synchronously, which facilitates the moving plate 5 to push the support sleeve 3 to move, thereby supporting the pulleys of different sizes.
[0025] refer to Figure 3 The first limiting component 8 includes a first limiting groove 81 and a first limiting plate 82. The first limiting groove 81 is opened inside the front and rear sides of the movable groove 7 and is connected to the movable groove 7. The first limiting plate 82 is movably installed inside the first limiting groove 81. A movable block 11 is movably installed inside the movable groove 7. The outer side of the movable block 11 is fixedly connected to the inner side of the first limiting plate 82.
[0026] As a technical optimization of this utility model, the second limiting component 3 is set inside the movable groove 7. The movable block 11 moves inside the movable groove 7, which drives the first limiting plate 82 to move. The movement of the first limiting plate 82 cooperates with the first limiting groove 81 to limit the movement of the movable block 11, thereby preventing the movable block 11 from deviating during movement and affecting the balance of the support sleeve 3.
[0027] refer to Figure 3 The second limiting component 3 includes a second limiting groove 91 and a second limiting plate 92. The second limiting groove 91 is opened at the bottom of the support frame 2 and is provided with two sets. The two sets of second limiting plates 92 are movably installed inside the second limiting groove 91. The bottom of the second limiting plate 92 is fixedly connected to the top of the movable plate 5.
[0028] As a technical optimization of this utility model, the second limiting component 3 is set at the bottom of the inner wall of the support frame 2. The second limiting plate 92 moves synchronously with the moving plate 5. When the second limiting plate 92 moves, it cooperates with the second limiting groove 91 to limit the movement of the top of the moving plate 5, thereby preventing the moving plate 5 from tilting when it moves.
[0029] refer to Figure 3 A first side plate 12 is fixedly installed on the outer side of the movable plate 5. A cylinder 13 is fixedly installed on the top of the first side plate 12. A second side plate 14 is fixedly installed on the bottom of the movable block 11. The bottom of the second side plate 14 is fixedly connected to the output end of the cylinder 13.
[0030] As a technical optimization of this utility model, the cylinder 13 is installed on the first side plate 12 located on the outside of the movable plate 5. The output end of the cylinder 13 pushes the second side plate 14 to move and adjust. When the second side plate 14 moves, it drives the movable block 11 to move synchronously, thereby facilitating the adjustment of the support sleeve 3 by the movable block 11.
[0031] refer to Figure 1 A support rod 15 is fixedly installed on the inner side of the movable block 11. The end of the support rod 15 away from the movable block 11 is fixedly connected to the outer side of the support sleeve 3. A connecting groove 16 is provided on the inner side of the support sleeve 3.
[0032] As a technical optimization of this utility model, the support rod 15 is set inside the movable block 11. The movable block 11 moves to drive the support rod 15 and the support sleeve 3 to move synchronously. The pulley shaft is inserted through the connecting groove 16 inside the support sleeve 3, thereby supporting the pulley.
[0033] refer to Figure 2 and Figure 3 The control panel 10 has a control button 17 fixedly installed on its front side. The control button 17 is electrically connected to the dual-head motor 61 and the cylinder 13 via wires.
[0034] As a technical optimization of this utility model, the control button 17 located on the front of the control panel 10 can be used to start and stop the dual-head motor 61 and the cylinder 13, thereby facilitating the support of the pulley and making it easier to inspect the pulley.
[0035] The working principle and usage process of this utility model are as follows: In use, pressing the control button 17 starts the cylinder 13, which pushes the second side plate 14 to move and adjust via the start output. As the second side plate 14 moves, it drives the movable block 11 to move synchronously. The movable block 11 moves within the movable groove 7, causing the first limiting plate 82 to move. The movement of the first limiting plate 82, in conjunction with the first limiting groove 81, limits the movement of the movable block 11, thus preventing it from shifting and affecting the balance of the support sleeve 3. The movement of the movable block 11 drives the support rod 15 and the support sleeve 3 to move synchronously, and the pulley shaft is connected via the connecting groove 16 inside the support sleeve 3, thereby balancing the pulley. The wheels provide support. Pressing control button 17 starts the dual-head motor 61, which drives the bidirectional screw 62 to rotate through its output. The rotation of the bidirectional screw 62 causes the adjusting plate 63 to move and adjust within the adjusting groove 64. When the adjusting plate 63 moves, it drives the moving plate 5 to move synchronously, which facilitates the moving plate 5 to push the movable block 11, support rod 15, and support sleeve 3 to move, thereby supporting pulleys of different sizes. The movement of the moving plate 5 drives the second limiting plate 92 to move synchronously. When the second limiting plate 92 moves, it cooperates with the second limiting groove 91 to limit the movement of the top of the moving plate 5, thereby preventing the moving plate 5 from tilting during movement.
[0036] In summary: This support frame for pulley detection in lifting machinery, by setting up a double-headed motor 61, a first limiting groove 81, and a second limiting groove 91, drives a bidirectional screw 62 to rotate via the output end of the double-headed motor 61. The rotation of the bidirectional screw 62 causes the adjusting plate 63 to move within the adjusting groove 64 for adjustment. When the adjusting plate 63 moves, it drives the moving plate 5 to move synchronously, thus facilitating the movement of the support sleeve 3 to support pulleys of different sizes. The movement of the movable block 11 within the movable groove 7 drives the first limiting plate 82 to move. The movement of the first limiting plate 82, in conjunction with the first limiting groove 81, limits the movement of the movable block 11, thereby preventing the movable block from moving. 11. When moving, deviation occurs, affecting the balance of the support sleeve 3. The movement of the moving plate 5 drives the second limiting plate 92 to move synchronously. When the second limiting plate 92 moves, it cooperates with the second limiting groove 91 to limit the movement of the top of the moving plate 5, thereby preventing the moving plate 5 from tilting during movement. This solves the problem that because the support frame cannot adapt to pulleys of different sizes, the pulleys may be subjected to uneven force distribution during the testing process, thus accelerating the wear of the pulley grooves. This wear not only affects the service life of the pulleys, but may also cause more serious mechanical failures. Every time a different size pulley is replaced, the support frame needs to be readjusted or replaced, which will greatly increase the preparation time and workload for testing and reduce the overall testing efficiency.
