Description
Technical Field
[0001] The present application relates to the technical field of wind turbine main shaft support, and in particular to a wind turbine main shaft support seat. Background Art
[0002] The wind turbine main shaft is the core component of a wind turbine generator. It has the important task of converting the wind force received by the blades into mechanical energy and transmitting it to the generator. This energy conversion process is crucial to the efficient operation of the entire wind power generation system.
[0003] During storage and transportation, wind turbine main shafts are often supported on supports to reduce damage risk and improve stability. These supports effectively distribute the main shaft's weight and reduce direct contact with the ground or other hard surfaces.
[0004] However, traditional support blocks often use stacked wooden blocks. While this method is simple, it is inconvenient during the movement and adjustment of the wind turbine main shaft. Different wind turbine hub models may require wooden blocks of different sizes to adapt, which not only increases the complexity of preparation work but also may affect work efficiency.

[0029] The following is combined with Figure 1-Figure 2 This application is described in further detail.
[0030] The embodiment of the present application discloses a wind turbine main shaft support seat.
[0031] A wind turbine main shaft support comprises a base 1, a support base 2, a lifting assembly 3, and a support assembly 4. A guide rail system is installed within the operating area. The base 1 moves on the guide rail system via a moving unit 11. The support base 2 is located above the base 1 and can move vertically. The lifting assembly 3 is used to control the vertical movement of the support base 2. The support assembly 4 is used to support the support base 2 after it reaches a predetermined height.
[0032] When placing the wind turbine main shaft, the placement seat 2 is adjusted to the required position through the lifting component 3 according to the placement height requirement of the wind turbine main shaft, and the placement seat 2 is supported by the support component 4. Then, the wind turbine main shaft is placed on the placement seat 2.
[0033] The base 1 is made of high-strength steel and equipped with multiple rollers at its bottom. These rollers roll in conjunction with the guide rail system to ensure smooth movement of the base 1. The forward and reverse rotation of the drive motor controls the rotation direction of the rollers, thereby achieving precise movement of the base 1 along the guide rail system.
[0034] The concave design of the mounting base 2 allows for multi-point contact when the wind turbine main shaft is placed on it, providing uniform and stable support. The concave edges and support points are treated with special processes, such as chrome plating or coating with wear-resistant materials, which not only enhances durability but also significantly reduces wear caused by friction, extending the service life of the equipment.
[0035] The lifting assembly 3 consists of a drive unit 31, a control system 32, a position detection unit 33, and a guide unit 34, all electronically connected to each other for coordinated operation. The control system 32 directs the drive unit 31, precisely moving the support 2 vertically. The position detection unit 33 monitors and provides real-time feedback on the current height of the support 2, ensuring accurate lifting. The guide unit 34 ensures that the support 2 maintains the correct orientation during vertical movement, preventing deviation.
[0036] Drive unit 31 utilizes a vertically mounted hydraulic cylinder, its top connected to the bottom of base 1 and its bottom connected to the top of stand 2. Control system 32 precisely controls the cylinder's movement, achieving vertical lifting of stand 2. A multi-stage buffering mechanism within the cylinder ensures smooth lifting and lowering while also preventing shock and vibration from rapid movement.
[0037] The position detection unit 33 is equipped with an infrared ranging sensor, which is installed on the side wall of the placement seat 2. It can accurately measure and transmit the height information of the placement seat 2 to the control system 32 in real time, ensuring accurate control and feedback of the position during the lifting process.
[0038] The guide unit 34 consists of multiple vertically arranged guide rods, the bottom ends of which are fixed to the base 1. The bottom of the placement base 2 is designed with guide holes that match the guide rods. A sliding fit between the two ensures precise guidance. The guide rods are coated with a low-friction material, such as polytetraethylene (PTFE) and its compounds, which significantly reduces friction and ensures smooth sliding of the guide rods within the guide holes. To further enhance smooth sliding, the side walls of the guide holes are specially designed with oiling holes 21 for regular lubrication, reducing wear and extending the service life of the equipment.
[0039] The support assembly 4 is located between the base 1 and the placement seat 2, and is composed of a plurality of pads 41 distributed in the vertical direction. The tops of these pads 41 are in contact with the bottom of the placement seat 2, and the bottoms are in contact with the base 1, providing stable support for the placement seat 2. Positioning grooves 411 are designed on the side walls of the pads 41, which are plugged into the guide rods to ensure that the support assembly 4 can be correctly positioned. Handles 42 are installed at both ends of the pads 41 to facilitate adjustment and positioning by the operator, thereby improving the convenience and accuracy of operation. The pads 41 can also be placed on the base 1 for storage, so as to save the space occupied by the base block, and the pads 41 can also be transported by the base 1 to improve the convenience of moving the pads 41.
[0040] The implementation principle of a wind turbine main shaft support seat in an embodiment of the present application is as follows: when placing the wind turbine main shaft, the bottom roller of the base 1 rolls with the guide rail system, and is controlled by a driving motor to achieve smooth and precise movement of the base 1 along the guide rail. The placement seat 2 is designed as a concave structure, which contacts the wind turbine main shaft at multiple points to provide uniform support. Its edges and support points are specially processed to enhance durability and reduce wear. The lifting assembly 3 is composed of a drive unit 31, a control system 32, a position detection unit 33 and a guide unit 34, which work together to control the precise vertical movement of the placement seat 2. The position detection unit 33 monitors the height in real time through an infrared ranging sensor to ensure lifting accuracy. The multi-stage buffering mechanism of the driving cylinder ensures the smoothness of the lifting action and avoids impact and vibration. The low friction coefficient material and the oil filling hole 21 design of the guide unit 34 ensure the smooth sliding of the guide rod in the guide hole and reduce wear. The support assembly 4 is composed of a pad 41, which cooperates with the guide rod through a positioning groove 411 to ensure correct positioning. The handle 42 on the pad 41 is convenient for the operator to adjust, thereby improving the convenience and accuracy of operation.
[0041] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
