[0025] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features.

[0026] The following is combined with Figure 1-4 This application is described in further detail.

[0027] The utility model provides a crane maintenance platform, referring to Figure 1 and Figure 2 The crane maintenance platform includes a load-bearing platform 1 and a tool lifting mechanism 2. The load-bearing platform 1 is suitable for connecting to a crane so that workers can stand and perform crane maintenance. The tool lifting mechanism 2 is installed on the load-bearing platform 1 and is suitable for lifting parts or tools. A guardrail 11 is provided on the top of the load-bearing platform 1. A plurality of storage boxes 12 are spaced apart on the guardrail 11. Different types of fasteners or smaller parts can be placed in corresponding storage boxes 12, making it easy to quickly find the corresponding fasteners and parts for assembly after maintenance.

[0028] A reinforced support frame 13 is welded to the bottom of the platform 1 and secured to the crane. This provides stable support at all corners of the platform 1, ensuring its stability. The crane is also equipped with a climbing ladder, allowing maintenance personnel to access the platform 1 and inspect the electric hoist. A doorway adapted to the ladder's width is located on the side of the guardrail 11 near the ladder, making it easy for maintenance personnel to access the platform 1.

[0029] Reference Figure 2 and Figure 3 A baffle 14 is welded to the top of the platform 1 to prevent fasteners or parts placed on the platform 1 from rolling or being kicked to the ground during maintenance, causing loss or injuring workers below. The guardrail 11 is located inside the baffle 14, which can provide a larger space inside the guardrail 11 and also prevent the baffle 14 from interfering with maintenance personnel's operations inside the guardrail 11.

[0030] A hook 121 is fixedly mounted on the outer wall of one side of the storage box 12. The storage box 12 can be hung at any position on the guardrail 11 via the hook 121. Maintenance personnel can then move the storage box 12 according to actual conditions to locate it in the most convenient position for them, allowing them to easily place fasteners or parts into the corresponding storage box 12 during maintenance. After being hung on the guardrail 11, the storage box 12 can be located inside or outside the carrying platform 1. If the storage box 12 interferes with the maintenance personnel's movement or work on the carrying platform 1, the storage box 12 is placed outside the carrying platform 1. Otherwise, the storage box 12 is placed inside the carrying platform 1.

[0031] Reference Figure 3 and Figure 4 A telescopic assortment box 15 is placed on top of the carrying platform 1. The box 15 has multiple, disconnected storage cavities 153. The size of any of the storage cavities 153 can be adjusted by adjusting the length of the corresponding position of the telescopic assortment box 15. When the telescopic assortment box 15 is not in use, it can be folded up and stored, eliminating the need for large space on the carrying platform 1 and providing more operating space for maintenance personnel.

[0032] The telescopic assortment box 15 includes a connecting plate 151 and a bellows 152. Multiple connecting plates 151 and multiple bellows 152 are provided, with one bellows 152 positioned between two adjacent connecting plates 151. Both ends of the bellows 152 are fixedly connected to the corresponding two connecting plates 151. The bellows 152 have openings on their sidewalls for easy placement of items. Each bellows 152 forms a storage cavity 153 with its corresponding two adjacent connecting plates 151. To adjust the size of a corresponding storage cavity 153, simply pull the two adjacent connecting plates 151 to extend or retract the corresponding bellows 152, resulting in simple operation and low cost.

[0033] A storage slot 16 is provided at a corner of the top of the carrying platform 1. When the telescopic classification box 15 is in a fully folded storage state, it can be stored in the storage slot 16 for further storage. When maintenance personnel place parts on the carrying platform 1 for maintenance, they can have more space.

[0034] Reference Figure 2 and Figure 3 The tool lifting mechanism 2 includes a tool placement box 21, a connecting rope 22 and a servo motor 23. A motor bracket 17 is welded to the top of the carrying platform 1. The motor bracket 17 is located on the side where the reinforcing support frame 13 is welded and fixed to the crane, so that the carrying platform 1 can stably support the motor bracket 17. One side of the motor bracket 17 cantilevers out of the carrying platform 1 and the guardrail 11, and the body of the servo motor 23 is fixedly installed at the position where the motor bracket 17 cantilevers out of the carrying platform 1. A winding drum 24 is provided on the motor shaft of the servo motor 23, and the servo motor 23 can drive the winding drum 24 to rotate. One end of the connecting rope 22 is fixedly connected to the winding drum 24; the other end is fixedly connected to the tool placement box 21. The servo motor 23 drives the connecting rope 22 to reel or unfold to drive the tool placement box 21 to rise and fall.

[0035] If a tool is forgotten or a replacement part is missing during maintenance, the tool box 21 can be lowered from the carrying platform 1 and the ground staff can directly place the required items into the tool box 21. The tool box 21 is then raised to the supporting platform. When the connecting rope 22 is fully reeled in, the bottom surface of the tool box 21 is higher than the top surface of the carrying platform 1, making it easier for maintenance staff to take out items from the tool box 21.

[0036] The implementation principle of the crane maintenance platform of the embodiment of the present application is as follows: when maintenance personnel need to remove corresponding different parts and components and place them on the load-bearing platform 1 for maintenance, different types of fasteners or smaller parts can be classified and placed in different storage cavities 153 of different storage boxes 12 or telescopic classification boxes 15. After the maintenance is completed, the fasteners or parts can be directly taken out from the corresponding storage boxes 12 or telescopic classification boxes 15. If it is felt that the telescopic classification boxes 15 occupy space on the load-bearing platform 1 in the expanded state, the bellows 152 of each section can be retracted and the telescopic classification boxes 15 in the fully retracted state can be placed in the storage slot 16, so that maintenance personnel have more operating space to move around on the load-bearing platform 1. In addition, the storage boxes 12 can also be hung on the outer wall of the guardrail 11, further reducing the occupation of the internal space of the load-bearing platform 1.

[0037] If you forget to bring the corresponding tools or lack the parts that need to be replaced during maintenance, you can lower the tool box 21 from the carrying platform 1 and let the ground personnel directly put the required items into the tool box 21 and then raise the tool box 21 to the supporting platform. There is no need for maintenance personnel to go down to the ground again.

[0038] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present utility model.
