[0002] The construction of wind turbine towers is a key link in the installation of wind power generation facilities, especially the construction process of concrete towers, which usually requires the use of large-scale lifting equipment to hoist each section of the tower. In traditional construction methods, after each section of the tower is hoisted, a crane is needed to lift the operating platform to the height of the new tower. This process not only increases the construction period, but also increases safety hazards and equipment utilization costs. The hoisting process usually needs to be operated in a complex construction environment, and because the platform lifting and hoisting need to be coordinated, the cumbersome operation and high risk put higher demands on construction personnel. With the development of the wind power industry, higher requirements are put forward for construction efficiency, construction period and safety. Therefore, seeking a new operating platform that can reduce the number of hoisting times, improve construction efficiency and improve safety has become an urgent need in the industry.

[0030] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Figures 1 to 3 An embodiment of a self-climbing operating platform for wind turbine concrete tower construction of the present invention is shown. The self-climbing operating platform for wind turbine concrete tower construction of this embodiment includes a lower platform assembly 10, an upper platform assembly 20, and a lifting drive assembly for driving the lower platform assembly 10 and the upper platform assembly 20 to rise and fall relative to each other. The lower platform assembly 10 is provided with a first connecting assembly for detachably connecting to a concrete tower 30 and a fence 12 for climbing to the upper platform assembly 20, and the upper platform assembly 20 is provided with a second connecting assembly for detachably connecting to the concrete tower 30.

[0032] The self-climbing operating platform for wind turbine concrete tower construction in this embodiment, the lower platform assembly 10 and the upper platform assembly 20 can be fixed to the concrete tower 30 through the first connecting assembly and the second connecting assembly respectively, and can be automatically lifted and lowered efficiently in a complex construction environment with the driving force of the lifting drive assembly, eliminating the need for multiple lifting operations in traditional construction, reducing the reliance on large lifting equipment, improving the efficiency of concrete tower 30 construction, and reducing the complexity and safety risks of lifting operations. The fence 12 can protect the safety of the workers on the lower platform assembly 10 on the one hand, and can also serve as a convenient climbing passage, making it convenient for the workers to climb to the upper platform assembly 20, thereby optimizing the use function of the platform; the upper platform assembly 20 is not only an important component for achieving self-climbing, but can also effectively block sunlight, etc., thereby improving the construction environment of the workers on the lower platform assembly 10 and providing more comfortable working conditions.

[0033] Furthermore, in this embodiment, the lower platform assembly 10 is further provided with a safety cage 13. The safety cage 13 can be used as a protective facility under special circumstances, which can effectively prevent workers from falling during the lifting process, further improving the safety guarantee in high-altitude operations.

[0034] As a preferred embodiment, the safety cage 13 is provided with a closable safety door (not shown in the figure). After the staff enters the safety cage 13, the safety door is closed to form a relatively closed protection structure, further improving safety.

[0035] Further, in this embodiment, the lower platform assembly 10 includes a lower platform 11, the fence 12 is arranged along the edge of the lower platform 11, the safety cage 13 is arranged in the middle of the lower platform 11, and the upper platform assembly 20 includes a ring-shaped upper platform 21, the upper platform 21 is located on the inner side of the fence 12, and the safety cage 13 is located on the inner side of the upper platform 21. This arrangement ensures that the upper platform 21 will not hinder the fence 12 and the safety cage 13 from rising and falling with the lower platform 11, and the structure is reasonable and effective.

[0036] Furthermore, in this embodiment, the lifting drive assembly includes a rack 14 provided on the lower platform 11, a rotating drive member 22 provided on the upper platform 21, and a gear 23 connected to the rotating drive member 22, the rack 14 is located on the inner side of the upper platform 21, and the gear 23 is meshed with the rack 14. The rotating drive member 22 can be, for example, an electric motor or a hydraulic motor, which can drive the gear 23 to rotate forward and reverse. When the upper platform 21 is connected and fixed to the concrete tower 30 through the second connecting assembly, the rotating driving member 22 drives the gear 23 to rotate, which can drive the rack 14 to rise, and the rack 14 then drives the lower platform 11, the fence 12 and the safety cage 13 to rise as a whole; on the contrary, when the lower platform 11 is connected and fixed to the concrete tower 30 through the first connecting assembly, the rotating driving member 22 drives the gear 23 to rotate in the opposite direction, which can rise along the rack 14, and then drives the upper platform 21 to rise as a whole. By controlling the rotation speed and the gear transmission ratio, it is possible to achieve efficient and accurate lifting (including lifting speed and position, etc.) in a complex construction environment, ensuring the safety and reliability of the platform during the construction process. Of course, in other embodiments, the relative lifting of the lower platform assembly 10 and the upper platform assembly 20 can also be achieved with the help of a cylinder, an oil cylinder, etc.

[0037] As a preferred embodiment, two groups of lifting drive components are provided and arranged relatively on both sides of the safety cage 13 , and the structure has good symmetry and balance, which is conducive to achieving smooth and stable lifting of the lower platform component 10 and the upper platform component 20 .

[0038] As a preferred embodiment, the first connection assembly includes a plurality of lower chains 15, which are arranged at intervals along the circumference of the lower platform assembly 10 (specifically, arranged at intervals along the circumference of the lower platform 11). Connectors such as hooks and rings can be provided on the inner wall of the concrete tower 30, and each lower chain 15 is connected to a corresponding hook, ring or other connector, respectively, so that the lower platform 11 can be reliably fixed and easily disassembled.

[0039] As a preferred embodiment, the second connection assembly includes a plurality of upper chains 24, which are arranged at intervals along the circumference of the upper platform assembly 20 (specifically, arranged at intervals along the circumference of the upper platform 21). Each upper chain 24 is connected to a corresponding hook, ring or other connecting member on the inner wall of the concrete tower 30, so that the upper platform 21 can be effectively fixed and easily disassembled.

[0040] like Figures 4 to 7 As shown, the process of self-climbing of the self-climbing operating platform for wind turbine concrete tower construction of the present invention comprises the following steps:

[0041] 1) If Figure 4As shown, when the entire operating platform is in the first section of the concrete tower 30, the entire operating platform is fixed to the inner wall of the first section of the concrete tower 30 through the lower chain 15. In this state, the staff can complete the relevant construction work of the first section of the concrete tower 30 on the lower platform 11. The upper platform 21 can effectively block the sunlight, etc., and provide a cool working environment for the staff.

[0042] 2) If Figure 5 As shown, after the relevant construction work of the first section concrete tower 30 is completed, the second section tower concrete 30 is hoisted using a crane. The staff climbs to the height of the second section concrete tower 30 through the fence 12 and fixes the upper chain 24 to the inner wall of the second section concrete tower 40.

[0043] 3) If Figure 6 As shown, after the upper chain 24 is fixed, the connection between the lower chain 15 and the first section of the concrete tower 30 is released. The staff enters the safety cage 13, closes the safety door, starts the rotary drive 22, and uses the gear 23 and rack 14 mechanism to pull the lower platform 11 to the height of the upper platform 21.

[0044] 4) The staff enters the upper platform 21, fixes the lower chain 15 to the inner wall of the second concrete tower 30, and releases the connection of the upper chain 24. After the operation is completed, the staff re-enters the safety cage 13 and closes the safety door.

[0045] 5) If Figure 7 As shown, the rotary drive member 22 rotates in the opposite direction, and the upper platform 21 is lifted to a predetermined height through the gear 23 and the rack 14 mechanism. After completion, the workers enter the lower platform 11 to carry out the relevant construction work of the second section of the concrete tower 30. The entire lifting process needs to ensure that the platform is lifted and lowered smoothly and remains stable, so as to ensure the safety of the workers.

[0046] 6) After the relevant construction work of the second section tower 30 is completed, repeat steps 2 to 5 until the construction of all concrete towers 30 is completed.

[0047] Through the above steps, the self-climbing operating platform for wind turbine concrete tower construction of the present invention can significantly improve the efficiency of concrete tower 30 construction, reduce dependence on lifting equipment, reduce safety risks during construction, optimize the working environment, and provide an efficient and safe solution for wind turbine tower construction.
