[0033] The present application provides a portable operating platform inside a tower barrel, which is used to provide a platform for maintenance personnel to stand on and improve safety during maintenance. The specific implementation process of the present application is described as follows.

[0034] Please refer to Figures 1 to 6 , a portable operating platform inside a tower barrel provided by the present application includes:

[0035] An extended platform and a platform support. One end of the platform support is movably connected to the extended platform, and the other end is used to fix the extended platform on the wind turbine climbing ladder 12. Among them, the extended platform includes a first folding plate 01, a second folding plate 02, and a folding member 03. The first folding plate 01 is located on both sides of the second folding plate 02 respectively, and the first folding plate 01 and the second folding plate 02 are connected by the folding member 03. The first folding plate 01 can rotate around the folding member 03, and the platform support is connected to the second folding plate 02.

[0036] The extended platform is the main working area for maintenance personnel, which can carry maintenance personnel and their tools to ensure sufficient space and stability during maintenance and repair operations inside the tower barrel. When the extended platform is fixed on the wind turbine climbing ladder 12, it is horizontally arranged to ensure that maintenance personnel can stand stably. The extended platform is usually made of lightweight but strong materials, such as aluminum alloy or high-strength steel, and the surface can be covered with anti-slip materials to increase safety during operation. A safety fence or guardrail can be set at the edge of the extended platform to prevent maintenance personnel from falling.

[0037] The extended platform is specifically composed of a first folding plate 01, a second folding plate 02 and a folding member 03. The first folding plate 01 is located on both sides of the second folding plate 02 respectively. The folding member 03 allows the first folding plate 01 to rotate relative to the second folding plate 02, so as to realize the folding and unfolding of the extended platform. When in use, the first folding plate 01 is unfolded to the required width, and then the platform bracket is installed to fix the extended platform on the fan ladder 12. After use, the first folding plates 01 on both sides can be folded up, and the platform can be removed from the ladder, which is convenient for storage and transportation. In an implementable way, the platform bracket can be stored in the space formed after the first folding plates 01 on both sides are folded. The folding angle between the first folding plate 01 and the second folding plate 02 is 0-90 degrees. After folding, it can reduce the occupied space and is also convenient for transportation.

[0038] The platform bracket is used to stably install the extended platform on the ladder of the fan tower, ensuring that the extended platform can maintain balance and stability at different heights. The extended platform is fixedly connected to the fan ladder 12 through the platform bracket, and the extended platform remains horizontal. One end of the platform bracket is fixedly connected to the bottom or side of the extended platform, and the other end is firmly fixed on the fan ladder 12.

[0039] In an alternative embodiment, the platform bracket includes a first bracket 04 and a second bracket 05. A heavy-duty door hinge and a connecting column 07 are provided on the second folding plate 02. The first bracket 04 is connected to the heavy-duty door hinge, and the second bracket 05 is connected to the second folding plate 02 through the connecting column 07. The first bracket 04 and the second folding plate 02 are connected through the heavy-duty door hinge. The heavy-duty door hinge is made of high-strength metal, such as stainless steel or high-quality alloy steel, to ensure that it can bear the total weight of the platform and the personnel and tools on it, and at the same time resist weathering and corrosion. The second bracket 05 can rotate around the connecting column 07, and the position of the connecting column 07 is close to the position of the heavy plate hinge 06.

[0040] Corresponding installation holes or slots matching the heavy-duty door hinge are reserved at the corresponding positions of the first bracket 04. During the installation process, first fix one end of the heavy-duty door hinge on the first bracket 04 to ensure firmness and no looseness. Then, connect the second folding plate 02 to the other end of the heavy-duty door hinge and tightly fix it through bolts, nuts or other fastening devices. In this embodiment, the second folding plate 02 can rotate around the heavy-duty door hinge.

[0041] In an alternative embodiment, vertical plates 08 are provided at the ends of both the first bracket 04 and the second bracket 05. The vertical plates 08 are integrally formed with the first bracket 04 and the second bracket 05. The vertical plates 08 are parallel to the fan ladder 12. When connecting, the vertical plates 08 are attached to the fan ladder 12, and the vertical plates 08 and the fan ladder 12 are tightly fixed through bolts, nuts or other fastening devices.

[0042] Please continue to refer to Figure 4 , in an alternative embodiment, a groove 09 is provided on one side of the vertical plate 08 facing the fan ladder 12, so that a part of the fan ladder 12 is snapped into the groove 09. The support rods on both sides of the fan ladder 12 are I-beams, and the groove 09 on the vertical plate 08 just fits onto the I-beam, thereby improving the stability of the platform bracket and reducing the horizontal shaking. In addition to reducing horizontal shaking, the design of the groove 09 also enhances the overall structural strength of the platform bracket, making the connection between the vertical plate 08 and the fan ladder 12 more firm and capable of withstanding greater loads and impact forces. When the vertical plate 08 is placed beside the fan ladder 12 and ready to be fixed, a specific part (such as the flange or web) of the I-beam will naturally snap into the groove 09 on the vertical plate 08, which not only increases the contact area between the vertical plate 08 and the fan ladder 12, but also significantly improves the connection firmness through the physical locking effect.

[0043] In addition, when the support rods on both sides of the fan ladder 12 are square structures, the vertical plate 08 covers the support rods. This cooperation can be continued to refer to Figure 6 .

[0044] In an alternative embodiment, the present application further includes a long screw 10. The long screw 10 passes through the cross bars on the vertical plate 08 and the fan ladder 12 respectively. The long screw 10 is used to fix the vertical plate 08 on the fan ladder 12. In actual use, the long screw 10 is passed through the vertical plate 08 and the fan ladder 12 respectively, and then locked with nuts to achieve a firm connection. In a feasible way, cross bars are provided on the fan ladder 12 (the cross bars are the bars that operators step on when climbing the ladder). The middle of the cross bar is provided with a through hole. Align the vertical plate 08 on the first bracket 04 with the end of the cross bar, and pass the long screw 10 through the vertical plate 08 and the cross bar and lock it with nuts to achieve a firm connection between the first bracket 04 and the fan ladder 12, and the second bracket 05 is connected to the adjacent cross bar in the same way. In this embodiment, the cross bars connected between the first bracket 04 and the second bracket 05 are adjacent, so there is an included angle between the first bracket 04 and the second bracket 05. By setting the included angle between the first bracket 04 and the second bracket 05, a triangular-like structure can be formed between the first bracket 04, the second bracket 05 and the fan ladder 12, thereby enhancing the stability of the entire platform bracket, ensuring that the extension platform is stably fixed on the fan ladder 12, and enhancing the load-bearing capacity of the extension platform. In actual use, the first bracket 04 and the second bracket 05 are vertically aligned and are respectively fixedly connected to the fan ladder 12.

[0045] In this alternative embodiment, a protective plate 13 is provided on the side of the fan ladder 12 away from the vertical plate 08. The protective plate 13 is fixed to the fan ladder 12 by means of a long screw 10 in cooperation with a nut. During specific connection, the long screw 10 is sequentially passed through the vertical plate 08, the cross bar on the fan ladder 12, and the protective plate 13, and then the nut is screwed onto the long screw 10 on one side of the protective plate 13. After tightening, the fixing of the long screw 10 is achieved. By providing the protective plate 13, it can play a role in protecting the fan ladder 12 and also enhance the connection strength.

[0046] In an alternative embodiment, the folding member 03 is a hinge or a hinge.

[0047] In an alternative embodiment, a kick plate 11 protruding upward is provided at the edge of the first folding plate 01. The kick plate 11 is similar to the safety fence or guardrail described above and is used to prevent maintenance personnel from stepping out of the extended platform area, playing a role in safety protection.

[0048] In an alternative embodiment, anti-slip patterns are provided on the upper surface of the extended platform. By providing the anti-slip patterns, the friction between the maintenance personnel and the extended platform can be increased, thereby preventing the maintenance personnel from sliding on the extended platform and improving safety.

[0049] Compared with the prior art, the present application performs maintenance on the fan ladder, provides a platform for maintenance personnel to stand on, improves the stability and safety during maintenance, and facilitates the maintenance process.

[0050] It should be noted that the above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the scope of the present application.
