TECHNICAL FIELD
[0001] The utility model relates to hoist device technical field, especially in a kind of wind driven generator cabin hoist device. BACKGROUND
[0002] During the assembly of wind driven generator, the traditional cabin hoist usually relies on large crane to carry out high-altitude operation, which is not only inefficient, but also has obvious deficiencies in accuracy and safety. First, when hoisting heavy components such as cabin, the traditional crane is difficult to provide sufficient stability, which can easily cause the components to shake greatly in the air, increase the risk of equipment damage, and may affect the installation accuracy. Secondly, for complex projects with extremely high installation location requirements, the traditional method often cannot achieve accurate positioning, resulting in large subsequent adjustment workload, long time consumption, and serious impact on overall construction progress and quality. Therefore, we propose a wind driven generator cabin hoist device. SUMMARY

[0007] By adopting the above technical scheme: the counterweight is fixedly installed at the rear upper end of the second moving frame, providing necessary balance effect, reducing the swing or inclination caused by load change, thereby ensuring the safety and stability of the hoisting process.

[0012] Through the above technical scheme, the second moving frame can be moved up and down along the second sliding groove by starting the forward-reverse driving motor inlaidly arranged in the stand to drive the transmission screw rod to rotate, and the position of the first moving frame can be adjusted synchronously by the traction belt, so that the height position adjustment of the wind turbine nacelle is realized.
[0013] Preferably, the hoisting body comprises a hoisting frame, the hoisting frame is fixedly arranged at a front end of the first moving frame, a moving groove is formed in a lower end of the hoisting frame, a moving block is slidably connected in the moving groove, and a lifting hook is fixedly connected to a lower end of the moving block.

[0015] Preferably, an adjusting screw rod is movably arranged in the moving groove and threadedly connected to the moving block, and a forward-reverse motor is fixedly connected to one end of the adjusting screw rod and fixedly arranged in the hoisting frame.
[0016] Through the above technical scheme, the moving block can be horizontally moved along the moving groove by driving the adjusting screw rod by the forward-reverse motor, so that the position of the lifting hook can be finely adjusted, and the wind turbine nacelle can be accurately and correctly installed to the predetermined position.
[0017] Compared with the prior art, the utility model has the following beneficial effects:
[0018] 1. By activating the forward and reverse drive motors embedded in the upright frame to drive the transmission screw to rotate, the second moving frame can move up and down along the second slide rail, and the position of the first moving frame can be adjusted synchronously with the help of the traction belt, thereby realizing the height adjustment of the wind turbine nacelle. Compared with the existing crane hoisting method, the device provided by this utility model is more stable, effectively avoiding large-scale shaking of the wind turbine nacelle during hoisting. Moreover, since the entire hoisting process is completed through mechanical control, the uncertainty caused by human operation is reduced, further improving the safety and stability of the operation, and also reducing the risk of equipment damage.
[0019] 2. By using a forward and reverse motor to drive the adjusting screw, the moving block can move horizontally along the moving slot, thereby fine-tuning the position of the hook and ensuring that the wind turbine nacelle can be accurately installed in the predetermined position. This design is particularly suitable for complex projects with extremely high installation precision requirements, ensuring perfect alignment between components, greatly improving installation quality and reducing the workload of subsequent adjustments caused by inaccurate positioning. It not only speeds up the overall construction progress but also improves the accuracy of the final assembly, laying a solid foundation for subsequent commissioning and operation.
