Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine construction, in particular to a wind turbine hoisting support device and a hoisting system. Background Art

[0002] The installation of wind turbines requires the use of large lifting equipment, which has a large weight and large outer dimensions. Since wind turbine installation sites are often located in complex terrain and meteorological conditions, especially mountain wind farms located in high-altitude areas, with large terrain undulations, steep terrain, and complex roads, it will cost a lot of money and time to transport large lifting equipment to the lifting point.

[0003] At present, the tower hoisting of mountain wind turbine generators is completed by the cooperation of the main crane (such as ZCC13000 crawler crane) and the auxiliary crane (such as 100t truck crane) with super-large hoisting capacity. During the hoisting, after the safety conditions are confirmed, the main crane and the auxiliary crane start to lift synchronously; the two cranes work in coordination, and the flanges always remain out of contact with the ground until the tower is erected. When the tower is a certain height above the ground (the distance from the ground is sufficient, and the tower can be turned over), the auxiliary crane side always keeps the height above the ground basically unchanged to cooperate with the lifting. The main crane continues to lift until the tower is basically in an upright state, the auxiliary crane is unloaded, the auxiliary crane rigging is released, and the main crane is erected. In order to ensure that the main crane and the auxiliary crane can perform normal hoisting operations, as well as the entry, exit and turning of the transportation equipment, a wind turbine hoisting platform with sufficient area is required, and the overall flatness and bearing capacity of the platform are required to be high. Most of the mountain wind turbines are located on the main ridge or branch ridge at a high altitude. Due to the special geographical location, the lifting platform site needs to be excavated and leveled according to the on-site terrain conditions, involving a large amount of excavation and backfilling work.

[0004] It can be seen that the current wind turbine hoisting scheme still has room for improvement. It should be optimized to improve the convenience of hoisting operations, while ensuring the stable progress of hoisting work, reducing equipment investment, thereby reducing the requirements for the construction site and avoiding major site damage. Therefore, a more reasonable technical solution should be proposed to solve the technical problems existing in the existing technology. Utility Model Content

[0005] In order to overcome at least one of the defects mentioned above, the utility model proposes a wind turbine hoisting support device and a hoisting system. The support device can assist in supporting the long components of the wind turbine (such as the tower), and the horizontal to vertical hoisting operation can be quickly completed, thereby improving the convenience of the hoisting operation. Only one main crane is needed to complete the operation, which also reduces the hoisting foundation construction before hoisting and the damage to the environment.

[0006] In order to achieve the above purpose, the hoisting system disclosed in the utility model can adopt the following technical solutions:

[0007] A wind turbine hoisting support device includes a first support seat and a second support seat arranged on a hoisting foundation, the first support seat and the second support seat are both provided with a supporting curved surface for fitting against the cylindrical wall of a hoisting member, the second support seat includes a fixed portion and a deflection portion, the deflection portion fits against the cylindrical wall of the hoisting member and deflects with the hoisting member, and the fixed portion is provided with a supporting structure for supporting the bottom surface of the hoisting member.

[0008] The above-disclosed lifting support device supports the elongated lifting parts, and applies supporting force from both ends of the lifting parts to keep the lifting parts stably placed. During the lifting process, the second support seat can support the deflected lifting parts in real time until they reach the final upright state. This greatly improves the convenience of lifting support, simplifies the coordination of lifting equipment, and reduces the requirements for the lifting working environment.

[0009] Further, in the present invention, the structure of the first support seat can be constructed in a variety of forms, which are not limited to the only one. Here, an optimization is made and one feasible option is proposed: the first support seat includes a first mounting portion and a first supporting portion, and the supporting curved surface is located on the first supporting portion. When such a solution is adopted, the first mounting portion can be constructed as a platform-shaped structure, and the first supporting portion can be constructed as a supporting wall structure.

[0010] Furthermore, the structure of the second support seat can be optimized, and one feasible option is proposed here: the deflection portion of the second support seat forms a supporting curved surface, and also forms an abutment portion for abutting the bottom surface of the hanging member. When such a solution is adopted, the deflection portion can adopt a wall-type structure, and the abutment portion can be integrally formed with the deflection portion.

[0011] Furthermore, in the present invention, the structure of the abutment portion is not limited solely, and an optimization is performed here and one of the feasible options is proposed: the abutment portion forms an inner curved surface coaxial with the supporting curved surface of the second support seat, the radius of the inner curved surface is smaller than the supporting curved surface, and an abutment surface for abutting the bottom of the hanging part is formed between the inner curved surface and the supporting curved surface.

[0012] Furthermore, the support structure in the utility model can be constructed in various forms, which are not limited to the only one. Here, an optimization is made and one feasible option is proposed: the support structure includes a support platform arranged on the fixed part, when the deflection part is deflected to the horizontal, the height of the support platform is equal to the height of the abutment part, and the support platform and the abutment part support the bottom of the hanging part at the same time. When such a solution is adopted, the support platform can adopt a long strip structure.

[0013] The above content discloses a supporting device, and the utility model also provides an overall lifting system.

[0014] A wind turbine hoisting system adopts the support device described above, including a hoisting foundation, on which a first support seat and a second support seat are arranged in a straight line; and also includes a hoisting machine, which is connected to the top of the hoisting part through a hoisting connection assembly.

[0015] Furthermore, the number of the hoisting machines is one.

[0016] Furthermore, the hoisting connection assembly includes a hoisting rope and a connecting flange.

[0017] The utility model also discloses a hoisting method of the hoisting system:

[0018] A method for hoisting a wind turbine generator, using the hoisting system described above, comprises:

[0019] Smooth out a hoisting foundation surface from the surrounding environment of the installation location, and install a first support seat and a second support seat on the hoisting foundation surface;

[0021] The lifting member is lifted by the lifting machine and deflected upward, and the deflection portion and the abutment portion of the second support seat are kept in close contact with the lifting member until the lifting member is deflected to stand upright;

[0022] Fix the lifting parts to complete the lifting.

[0023] Furthermore, during the hoisting process, the hoisting machine always applies a vertical upward force to the hoisting member, and the lifting point is always located directly above the upper end of the hoisting member.

[0024] Compared with the prior art, some beneficial effects of the technical solution disclosed in the utility model include:

[0025] The utility model supports the long strip hoisting parts through the supporting device and can deflect with the long strip hoisting parts, which greatly improves the convenience of hoisting, reduces the investment and use of equipment, reduces the requirements for the hoisting environment and site, and reduces the damage to the environment.
