Description

Technical Field

[0001] This utility model relates to the field of material handling equipment technology, specifically a yaw-driven material handling device for wind turbine generators. Background Technology

[0002] Existing technology involves erecting scaffolding inside the wind turbine nacelle and using hand-operated hoists to pull and manually move the yaw drive unit for maintenance and replacement. This high-intensity work and unstable scaffolding accelerate the physical exhaustion of personnel and increase the risk of the yaw drive unit falling off, raising safety hazards. Furthermore, the limited space inside the wind turbine nacelle makes scaffolding installation and dismantling difficult, increasing working time and reducing efficiency. Unlike existing technology, this proposal can significantly reduce the labor intensity of personnel maintaining the yaw drive unit, improving work efficiency, accuracy, and safety, preventing accidents during operations. Utility Model Content

[0003] The purpose of this invention is to provide a yaw drive conveying device for wind turbine units to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a wind turbine yaw drive transport device, comprising a first support frame, a second support frame, and a first lifting beam, wherein the second support frame is fixedly connected to the side end of the first support frame, the first lifting beam is fixedly connected to the upper end of the first support frame and the second support frame, the fourth support frame is fixedly connected to the side end of the third support frame, and the third lifting beam is fixedly connected to the third support frame and the fourth support frame;

[0005] The lower ends of the first and third lifting beams are fixedly connected to the second lifting beams by the first washer and screws. The lower ends of the second lifting beams are supported by the support base. The first and third lifting beams are both equipped with trolleys. The lower end of the trolley on the first lifting beam is equipped with a first protective cover, and the lower end of the first lifting beam on the third lifting beam is equipped with a second protective cover.

[0006] Specifically, a second gasket is provided at the connection position between the second support frame and the first lifting beam for cushioning and protection.

[0007] Specifically, the lower end of the first support frame is fixed to the first frame body by a third washer and a second hexagonal nut, and the first frame body is located inside the wind turbine unit.

[0008] Specifically, the second support frame is fixed to the second frame body by the first hexagonal nut and the third washer, and the second frame body is also located inside the wind turbine.

[0009] Specifically, the connection between the first support frame and the first frame body is not horizontal, but has an inclination angle of degrees, and the first support frame supports the first lifting beam in a vertical state.

[0010] Specifically, the connection between the second support frame and the second frame body is not horizontal, but has an inclination angle of degrees, and the second support frame supports the first lifting beam in a vertical state.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] When using the tooling for replacing the yaw drive unit of a wind turbine generator set, multiple portal beams and I-beams are combined. The portal beams are fixed to the gearbox and main shaft support within the nacelle, providing sturdy and reliable mounting points for the hoists during transport of the yaw drive unit. After the portal beams and I-beams are fixed in place, the yaw drive unit is lifted by hand-operated hoists. By setting multiple hand-operated hoists on different portal beams and I-beams, the yaw drive unit can be moved alternately within the confined and complex nacelle. This significantly reduces the physical labor intensity of personnel and avoids the possibility of crushing injuries during manual handling, ensuring personnel safety and facilitating operation. It improves both work efficiency and accuracy. This solution is labor-saving, safe, and easy to install and disassemble, increasing the safety and reliability of personnel during the replacement of the yaw drive unit of the wind turbine generator set, reducing the physical exertion of maintenance personnel, and improving work efficiency.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-7 This utility model provides a technical solution: a wind turbine yaw drive transport device, including a first support frame 1, a second support frame 2, and a first lifting beam 3. The second support frame 2 is fixedly connected to the side end of the first support frame 1, and the first lifting beam 3 is fixedly connected to the upper end of the first support frame 1 and the second support frame 2. The fourth support frame 20 is fixedly connected to the side end of the third support frame 18, and the third lifting beam 19 is fixedly connected to the third support frame 18 and the fourth support frame 20.

[0023] The lower ends of the first lifting beam 3 and the third lifting beam 19 are both fixedly connected to the second lifting beam 7 via the first washer 9 and screws 10. The lower end of the second lifting beam 7 is supported by the support seat 8. Both the first lifting beam 3 and the third lifting beam 19 are equipped with trolleys 4. The lower end of the trolley 4 on the first lifting beam 3 is connected to the first protective cover 5, and the lower end of the first lifting beam 3 on the third lifting beam 19 is connected to the second protective cover 6. By simply fixing the first support frame 1 and the second support frame 2 to the bottom first frame and second frame respectively, support can be provided, thus limiting the support of the first lifting beam 3. At the same time, the third support frame 18 and the fourth support frame 20 also support the third lifting beam 19 in the same way, thereby facilitating the movement of the first lifting beam 3. The trolley 4 is equipped with an electric hoist, which can lift the first protective cover 5. The connecting rod is connected to the top of the first lifting beam 3 via screws 10. This allows for support and protection of the first lifting beam 3 from the upper position. The trolley 4 can also lift the second protective cover 6. The side end of the first lifting beam 3 is fixedly connected to the second lifting beam 7 via the support seat 8, the first gasket 9, and the screw 10, thus achieving the docking purpose and facilitating the transfer of the first protective cover 5 and the second protective cover 6. At the same time, the two trolleys 4 can manually detach the first protective cover 5 or the second protective cover 6 at the connection position and then reconnect to the side trolley 4 for continuous transmission. There is a certain height difference between the two trolleys 4, and the lower ends of the first support frame 1 and the second support frame 2 are connected to the first frame and the second frame. The first frame and the second frame are the structures originally installed on the wind turbine, which facilitates docking. The connection position is not necessarily horizontal, but the frame of the first support frame 1 and the second support frame 2 is vertical, thus providing stable support for the first lifting beam 3.

[0024] A second gasket 14 is provided at the connection position between the second support frame 2 and the first lifting beam 3 for buffer protection.

[0025] The lower end of the first support frame 1 is fixed to the first frame body by the third washer 16 and the second hexagonal nut 17. The first frame body is located inside the wind turbine unit.

[0026] The second support frame 2 is fixed to the second frame body by the first hexagonal nut 15 and the third washer 16. The second frame body is also located inside the wind turbine unit.

[0027] The connection between the first support frame 1 and the first frame is not horizontal, but has an inclination angle of 10 degrees. The first support frame 1 supports the first hanging beam 3 in a vertical state.

[0028] The connection between the second support frame 2 and the second frame is not horizontal, but has an inclination angle of 10 degrees. The second support frame 2 supports the first lifting beam 3 in a vertical state.

[0029] Working principle: When needed, the user only needs to fix the first support frame 1 and the second support frame 2 to the bottom first frame and second frame respectively to provide support and limit the support of the first lifting beam 3. At the same time, the third support frame 18 and the fourth support frame 20 also support the third lifting beam 19 in the same way, thus facilitating the movement of the first lifting beam 3. The trolley 4 is equipped with an electric hoist, which can lift the first protective cover 5. The connecting rod is connected to the top of the first lifting beam 3 by screws 10, thus providing support and protection for the first lifting beam 3 from the top. The trolley 4 can also lift the second protective cover 6. The side end of the first lifting beam 3 is fixedly connected to the second lifting beam by the support seat 8, the first washer 9, and screws 10. 7. This achieves the docking purpose, facilitating the transfer and handling of the first protective cover 5 and the second protective cover 6. At the same time, the two trolleys 4 can manually unhook the first protective cover 5 or the second protective cover 6 at the connection position, and then connect with the side trolley 4 for continuous transmission. There is a certain height difference between the two trolleys 4, and the lower ends of the first support frame 1 and the second support frame 2 are connected to the first frame and the second frame. The first frame and the second frame are the structures originally set on the wind turbine, which facilitates docking. The connection position is not necessarily horizontal, but the frame of the first support frame 1 and the second support frame 2 is vertical, thus providing stable support for the first lifting beam 3. The object is connected and lifted inside the first protective cover 5 and the second protective cover 6 to complete the work.
