Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of a hub operation platform for a wind turbine generator set, in particular to a hub assembly operation platform for a wind turbine generator set. Background Art
[0002] With the development and upgrading of current wind turbine generator sets, the hub structure of the unit gradually increases in size and height. There is no platform or foothold for workers to stand inside the hub, and the unique three-sided structure of the hub makes it easy to cause difficulties in installing internal components.
[0003] The existing internal assembly operation method is to place a lift truck inside the hub and operate on the platform of the lift truck. It can only meet the installation of components on one side, and the corner positions of the three-sided structure of the hub cannot be reached. When installing components on the other two sides, since the lift truck cannot turn inside the hub, it is necessary to lift the hub, rotate the hub or turn the lift truck, and then lower the hub to continue the operation. This method occupies the crane resources for a long time, has low efficiency, and frequent lifting of the hub is prone to safety accidents. Content of the Utility Model
[0004] The purpose of the utility model is to provide a hub assembly operation platform for a wind turbine generator set to solve the deficiencies in the prior art, enabling the operation platform to be radially lifted and horizontally unfolded, effectively solving the problems of no foothold for operators to stand, operation height, and installation of components at the included angle positions of the three-sided structure, reducing the installation difficulty, improving work efficiency, and eliminating potential safety hazards.
[0005] To achieve the above purpose, the technical solution provided by the utility model is: a hub assembly operation platform for a wind turbine generator set, including a chassis, a first flap, a first flap support, a second flap, a second flap support, a lifting platform, and a lifting mechanism; a hexagonal chassis platform is provided at the top of the chassis, a middle vacancy is provided in the middle of the chassis platform, and the lifting mechanism is installed in the middle vacancy and connected to the lifting platform; the first flap and the second flap are rotatably installed at the edge of the chassis platform, and the first flap and the second flap are arranged at intervals along each side of the chassis platform. The length of the second flap is greater than that of the first flap. The two ends of the first flap support are respectively connected to the first flap and the chassis, and the two ends of the second flap support are respectively connected to the second flap and the chassis.
[0006] Further, the first flap is a rectangular flap.
[0007] Further, the second flap is a triangular flap.
[0008] Furthermore, the lifting mechanism includes an electric winch and a chain sling. The electric winch is electrically connected to a power source. A steel wire rope is wound around the outside of the electric winch. One end of the steel wire rope is connected to the chain sling, and the other end of the chain sling is fixed inside the hollow position. The electric winch is connected to the lifting platform through a transmission rod.
[0009] Furthermore, the wind turbine hub assembly operation platform further includes a telescopic ladder. One end of the telescopic ladder is connected to the bottom of the chassis, and the other end of the telescopic ladder passes through the hollow position and is connected to the lifting platform.
[0010] Compared with the prior art, the present invention has the following advantages and beneficial effects:
[0011] Compared with the traditional hub assembly operation method of placing a lifting vehicle, the present invention can avoid occupying more resources, improve work efficiency, reduce operation safety risks. At the same time, the horizontally deployed flap can realize the installation of components at the middle height inside the hub and meet the operation requirements at the three included angle positions of the hub, while the radially lifting platform can realize the installation of components at the middle and upper heights inside the hub and meet the installation requirements of components at various heights inside the hub.

[0015] The present invention will be further described below in conjunction with specific embodiments.
[0016] Refer to Figures 1 to 3 As shown, the wind turbine hub assembly operation platform provided in this embodiment includes a chassis 1, a first flap 2, a first flap support 3, a second flap 4, a second flap support 5, a lifting platform 6, a lifting mechanism a, and a telescopic ladder 9;
[0017] At the top of the chassis 1, there is a hexagonal chassis platform 101. In the middle of the chassis platform 101, there is a hollow position. The lifting mechanism a includes an electric winch 7 and a chain sling 8. The electric winch 7 is electrically connected to a power source (not shown in the figure). A steel wire rope is wound around the outside of the electric winch 7. One end of the steel wire rope is connected to the chain sling 8, and the other end of the chain sling 8 is fixed in the hollow position. The electric winch 7 is connected to the lifting platform 6 through a transmission rod. One end of the telescopic ladder 9 is connected to the bottom of the chassis 1, and the other end of the telescopic ladder 9 passes through the hollow position and is connected to the lifting platform 6;
[0018] The first flap 2 and the second flap 4 are rotatably installed at the edge of the chassis platform 101, and the first flap 2 and the second flap 4 are arranged at intervals along the six sides of the chassis platform 101. The first flap 2 is a rectangular flap, and the second flap 4 is a triangular flap. The length of the second flap 4 is greater than the length of the first flap 2. Therefore, the second flap 4 can be used as an extended platform to extend to the three corners inside the hub b, and the first flap 2 can be used as another extended platform to extend to the three surfaces inside the hub b for operators to perform installation operations. Both ends of the first flap support 3 are respectively connected to the first flap 2 and the chassis 1, and both ends of the second flap support 5 are respectively connected to the second flap 4 and the chassis 1.
[0019] The specific usage method of the wind turbine hub assembly operation platform is as follows: Place the operation platform at the corresponding work station, lift the hub b, and lower it until it covers the operation platform. Open the first flap 2 and the second flap 4, and support them with the first flap support 3 and the second flap support 5. Then, the lifting platform 6 performs the lifting function through the lifting mechanism a. The operator climbs to the top of the lifting platform 6 through the telescopic ladder 9. The first flap 2 and the second flap 4 are used to install the middle-layer components inside the hub b; the second flap 4 is used to install the components at the three-sided included angle position inside the hub b; adjust the lifting height of the lifting platform 6 to install the middle-layer and upper-layer components inside the hub b.
