Description

Technical Field

[0002] A wind power torsion arm (also known as a wind turbine torsion arm or a wind turbine torque arm) is an important component in a wind power generation unit. Its main function is to convert the wind force received by the wind turbine blades into torque and then transmit it to the gearbox or generator of the wind turbine. The torsion arm is usually made of high-strength materials, such as steel or composite materials, to ensure sufficient stiffness and durability. A high-precision torsion arm usually has a higher degree of adjustability and customization, and can be adjusted and optimized according to the specific wind farm environment and the requirements of the power generation unit to achieve the best performance.

[0003] The existing high-precision wind power torsion arms are usually connected to the gearbox through flanges. The flange connection usually includes bolts and nuts, and they are fastened together to ensure a firm connection. The installation of the nut-bolt connection usually requires precise adjustment and fastening, which may increase the complexity and time cost of the installation process. Moreover, the nut-bolt connection needs to be regularly inspected and maintained to ensure the fastening state of the connecting components, especially under harsh environmental conditions, which may increase the maintenance cost and downtime of the system. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that the existing high-precision wind power torsion arms are usually connected to the gearbox through flanges, and the installation process is complex, which may increase the maintenance cost and downtime of the system.

[0005] To solve the above technical problem, a technical solution adopted by the utility model is: a high-precision wind power torsion arm, including a gearbox main body. On one side of the gearbox main body, two first fixing blocks are fixedly connected. A fixing structure is arranged on the side of the first fixing block away from the gearbox main body. The fixing structure includes a clamping block fixedly connected to the first fixing block. The middle of the clamping block is in a concave state. A second fixing block is arranged outside the clamping block. A second chamber is arranged in the second fixing block, and a sliding cylinder is arranged in the second chamber.

[0006] The utility model is further arranged such that a plurality of first through holes are formed in the sliding cylinder, and a plurality of balls are respectively arranged in the first through holes. The balls cooperate with the clamping block. The first fixing block and the clamping block are integrally arranged. The bottom end of the inner wall of the second fixing block is arranged in an inclined plane.

[0007] Through the above technical solution, since the bottom end of the inner wall of the second fixing block is inclined, when the second fixing block approaches the engaging block, the ball will be pushed towards the engaging block and stuck in the groove on the engaging block, thereby fixing the gearbox to the torque arm, ensuring the accurate alignment and firm fixation of the connecting components, reducing the risk of loosening or misalignment of the connecting components, and improving the reliability and stability of the system.

[0008] The present utility model is further configured such that a sliding shaft is fixedly connected to the top end of the sliding cylinder, a return spring is sleeved on the sliding shaft, two ends of the return spring are respectively fixedly connected to the second fixing block and the sliding cylinder, and the sliding shaft is slidably connected to the second fixing block.

[0009] The present utility model is further configured such that a fixing cylinder is fixedly connected to one end of the second fixing block away from the first fixing block, two chutes are provided on the fixing cylinder, a second through hole is provided at the top end of the second fixing block, and the second fixing block and the fixing cylinder are integrally provided.

[0010] The present utility model is further configured such that a rotating handle is rotatably connected to the top end of the second fixing block, a first chamber is provided inside the rotating handle, a lever is provided inside the first chamber, the lever fixedly penetrates through the sliding shaft, and the lever cooperates with the chute.

[0011] The present utility model is further configured such that a torque arm main body is provided on one side of the gearbox main body, connecting blocks are fixedly connected to both sides of the torque arm main body, the connecting blocks are fixedly connected to the second fixing block, and the torque arm main body and the gearbox main body are fixedly connected through a fixing structure.

[0012] Through the above technical solution, rotating the rotating handle can achieve the installation and disassembly of the gearbox and the torque arm, enabling the connection between the wind power torque arm and the gearbox to be quickly disassembled and reinstalled, facilitating maintenance personnel to quickly perform maintenance or replace components when needed, and reducing the downtime and production losses of the system.

[0013] The beneficial effects of the present utility model are as follows:

[0014] By rotating the rotating handle of the present utility model, when the lever is clamped into the lowest part of the chute and the ball is clamped into the groove on the engaging block, the fixation of the gearbox and the torque arm is achieved. The fast installation design can ensure the accurate alignment and firm fixation of the connecting components, thereby reducing the risk of loosening or misalignment of the connecting components and improving the reliability and stability of the system. In case of system failure or emergencies, rotate the rotating handle in the reverse direction, the lever moves away from the lowest part of the chute, and the ball moves away from the groove of the engaging block, then the gearbox and the torque arm can be separated, which facilitates the maintenance personnel to quickly disassemble and repair when needed, reducing the system downtime and production losses. Moreover, the overall operation does not require special tools or complex operation steps, and the maintenance personnel can perform maintenance work or replace torque arms or gearboxes of different types or specifications more quickly and simply, greatly improving the work efficiency.
