Description

Technical Field

[0001] This utility model belongs to the field of mechanical assembly process equipment technology, specifically relating to a fastening fixture for a fixed screw sleeve of a pitch control cabinet. Background Technology

[0002] With the increasing global demand for clean energy, wind power, as an important renewable energy source, has been widely applied and developed. To improve the performance and efficiency of wind turbine generators, precise control of the blades is necessary to adapt to different wind speeds and directions. The pitch control cabinet, as one of the core control devices of a wind turbine generator, enables precise adjustment of the blade angle, thereby improving the power generation efficiency and stability of the wind turbine generator. Pitch control technology can change the angle of attack of the airflow on the blades by adjusting the blade pitch angle, thus controlling the aerodynamic torque and power captured by the wind turbine. Under different wind speed conditions, by reasonably adjusting the blade angle, the wind turbine generator can always operate in the optimal power generation state, improving power generation efficiency. At the same time, the pitch control cabinet can also quickly adjust the blade angle in case of sudden wind speed changes or other abnormal situations, reducing the impact of wind on the generator and enhancing the stability and safety of the wind turbine generator.

[0003] Traditional manual tools require frequent disassembly from the threaded sleeve to adjust the rotation direction, which is inefficient. The pitch control cabinet has a small internal space and different threaded sleeve models. Traditional tools cannot be flexibly disassembled to adapt to different threaded sleeves, and the threads are easily damaged when tightening multiple tooling parts simultaneously.

Detailed Implementation

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0018] Example Reference Figures 1-4 This embodiment of the present invention provides a pitch control cabinet fixing screw fastening fixture, including a handle 101, a sleeve nut 102 movably connected to the bottom of the handle 101, a first extension rod 103 movably connected to the bottom of the sleeve nut 102, a ratchet assembly 104 fixedly installed at the bottom of the first extension rod 103, an extension rod assembly 105 sleeved at the bottom of the ratchet assembly 104, and a synchronization chuck assembly 106 sleeved at the bottom of the extension rod assembly 105.

[0019] Specifically, the ratchet assembly 104 includes a housing 104a fixedly installed at the bottom of the first extension rod 103, a knob 104b rotatably connected to the surface of the housing 104a, a push block 104c fixedly installed at the bottom of the knob 104b, a lever 104d rotatably installed inside the housing 104a, a spring 104e fixedly installed on the inner wall of the housing 104a, a limiting post 104f fixedly installed inside the housing 104a, a rotating post 104g rotatably connected to the inner wall of the housing 104a, a ratchet 104h fixedly installed on the surface of the rotating post 104g, and a first square tenon 104i fixedly installed at the bottom of the rotating post 104g.

[0020] Furthermore, rotating the knob 104b causes the actuating block 104c to move, pushing the lever 104d to swing and engage with the ratchet teeth of the ratchet 104h, thus achieving unidirectional movement of the ratchet 104h.

[0021] Preferably, the synchronous chuck assembly 106 includes a fixed plate 106a sleeved on the surface of the second square tenon 105c, a wrench post 106b fixedly installed on the surface of the fixed plate 106a, a T-shaped connector 106c movably connected to the side wall of the wrench post 106b, a connecting rod 106d movably connected to the side wall of the T-shaped connector 106c, and a fixing pin 106e in the inner cavity of the connecting rod 106d.

[0022] It should be noted that the four wrench posts 106b in the synchronous chuck assembly 106 are connected by a T-shaped connector 106c and a connecting rod 106d. When one of the wrench posts 106b is subjected to excessive force, it will be transmitted to the other three wrench posts 106b through the connecting rod 106d, so as to achieve uniform force distribution on the four wrench posts.

[0023] In use, the first extension rod 103 is movably connected to the handle 101 via the sleeve nut 102. The top of the outer shell 104a of the ratchet assembly 104 is fixed to the bottom of the first extension rod 103. The sleeve 105a of the extension rod assembly 105 is fitted onto the first square tenon 104i of the ratchet assembly. The fixing plate 106a of the synchronizing chuck assembly 106 is fitted onto the second square tenon 105c of the extension rod assembly. The knob 104b is rotated, the actuating block 104c moves, and the lever 104d is pushed to engage with the ratchet 104h. The T-shaped connector 106c is movably connected to the inner wall of the wrench column 106b, and the connecting rod 106d is movably connected to the inner wall of the T-shaped connector 106c, thus completing the assembly.

[0024] In summary, the coordination of the knob 104b, the actuating block 104c, and the lever 104d in the ratchet assembly 104 enables the ratchet 104h to rotate in one direction, allowing for continuous tightening of the threaded sleeves without repeated tool angle adjustments, reducing operation steps and improving efficiency. The extension rod assembly 105 is connected to the ratchet assembly 104 and the synchronous chuck assembly 106 via the first square tenon 104i and the second square tenon 105c, allowing for flexible disassembly and enhanced extensibility, making it adaptable to confined spaces and the use of different threaded sleeves. The wrench pins 106b in the synchronous chuck assembly 106 are linked to the connecting rod 106d via the T-shaped connector 106c, enabling simultaneous clamping of multiple threaded sleeves for synchronous tightening, while ensuring even force distribution on the four wrench pins 106b, preventing damage to the wrench pins 106b and the threaded sleeves.
